Effects of the Learning Together intervention on bullying and aggression in English secondary schools (INCLUSIVE): a cluster randomised controlled trial

Association of sedentary time with school bullying among adolescents in 74 countries: A population-based study

BACKGROUND

Numerous studies have demonstrated the association between sedentary behavior and bullying among adolescents. However, few have explored the "dose-response" relationship between the frequency of sedentary behavior and school bullying. We aimed to evaluate the "dose-response" relationship between leisure sedentary time and school bullying among adolescents.

METHODS

We used data from the most recent Global School-based Student Health Survey (GSHS), conducted between 2009 and 2019 from 74 countries. Multivariable logistic regression analysis was employed to investigate the association between leisure sedentary time and school bullying.

RESULTS

A total of 222,172 adolescents aged 12-17 years from 74 countries were included. Overall, 29.8 % of adolescents reported having sedentary time ≥ 3 h/d, and 14.9 % reported experiencing school bullying. Compared with sedentary time < 1 h/d, increased sedentary time (except for 1-2 h/d: OR = 1.02, 95 % CI = 0.83-1.24) were associated with school bullying (3-4 h/d: OR = 1.16, 95 % CI = 1.01-1.34; ≥5 h/d: OR = 1.40, 95 % CI = 1.23-1.58).

LIMITATIONS

The data assessing school bullying and sedentary time were derived from self-reported survey questionnaires, potentially introducing recall bias.

CONCLUSIONS

School bullying is still widespread globally, and is associated with an extended period of leisure sedentary time. Efforts to reduce sedentary behavior among adolescents may potentially make a substantial impact on reducing the incidence of school bullying.

Patterns of intra-cluster correlation coefficients in school-based cluster randomised controlled trials of interventions for improving social-emotional functioning outcomes in pupils: a secondary data analysis of five UK-based studies

BACKGROUND

The cluster randomised trial (CRT) design is increasingly used to evaluate the impact of school-based interventions for improving social-emotional functioning outcomes in pupils. Good knowledge is required on plausible values of the intra-cluster correlation coefficient (ICC) of the outcome to calculate the required sample size in such studies. Using data from five school-based CRTs in the UK, we estimate, and describe patterns in, ICCs for social-emotional functioning outcomes.

METHODS

Mixed effects linear regression models were fitted to estimate the ICC and variance components. Estimates for baseline data were obtained by fitting "null" models that had no predictor variables; estimates at follow-up were adjusted for trial arm status.

RESULTS

Five hundred and twenty-nine (529) ICCs were estimated. Variation across clusters in the outcomes was present at the school, year group and classroom levels. Overall, the ICCs were not markedly different between the primary and secondary school settings. Most of the school- and classroom-level ICCs were less than 0.04 for pupil-reported outcomes and less than 0.035 for parent-reported outcomes; a notable exception for pupil-reported outcomes was for outcomes that reflect a common experience shared by children, such as school climate, where the ICCs were as large as 0.1. The ICCs for teacher-reported outcomes (up to 0.1 at the school level and 0.2 at the classroom level) were larger than for pupil- and parent-reported outcomes. In the CRT that allocated schools to trial arms and only sampled one classroom from each school, the nominal school-level ICCs for teacher-reported outcomes took values up to 0.25. ICCs for teacher-reported measures of internalising behaviour problems and pro-social behaviour were larger than for externalising behaviour problems.

CONCLUSIONS

When randomising school clusters, sub-sampling of lower-level clusters such as classrooms should be accounted for in the sample size calculation. Teacher-reported ICCs are likely to be greater than those for pupil- and parent-reported outcomes as teachers will often provide data for many or all pupils in a given school or classroom. Differences across reporter type and across outcomes need to be considered when specifying plausible values of the ICC to calculate sample size.

Staff motivation and schools' capacities to sustain an intervention to prevent bullying and promote wellbeing in English secondary schools: a qualitative study

Introduction

Discontinuing effective school health interventions prevents new practices from reaching wider student populations and wastes investment in implementation. While reviews have consistently identified facilitators and barriers to the sustainment of school health interventions, the social processes underlying sustainment remain unclear. We explored the post-trial sustainment of "Learning Together," a whole-school intervention, found to be effective in preventing bullying and promoting wellbeing in English secondary schools. We examined how staff and students described its sustainment in the 2 years post-trial, what factors staff referred to in explaining their motivation to sustain it, and how schools' capacities affected sustainment.

Methods and materials

Learning Together involved training staff in restorative practice (RP) and supporting schools to implement a staff-student action group and a social and emotional learning curriculum. Using a case-study design, we collected qualitative data from five schools: staff and student interviews 1-year post-trial; staff interviews 2 years post-trial; and descriptive data from the original trial's process evaluation. The General Theory of Implementation guided our thematic analysis.

Results

No school sustained the intervention in its entirety. RP was continued by some individuals in all schools and was sustained at school-level in one school. The curriculum and action groups were discontinued in all schools, although actions initiated by the groups were sustained in two schools. Staff motivation to sustain components was affected by their perceived effectiveness, and individual motivations to sustain RP differed from whole-school commitment to sustaining the approach. Schools' capacities to sustain Learning Together were affected by: the prioritization of academic learning time; the frequent implementation of new initiatives; the timeliness of interventions with school improvements plans; and leadership engagement. Schools needed support to disseminate RP knowledge and skills school-wide and ensure consistent practice, and turnover adversely impacted on knowledge transfer.

Discussion

Sustainment was an intentional, labor-intensive, social process. Intervention developers should consider whether/how interventions are designed to work alongside, replace, or can refine existing practices, and should support schools to mainstream evidence-based interventions to sustain them at school-level.

An Ongoing Teacher Professional Development Programme to Enhance Critical Health Literacy Pedagogies and Assessment

ISSUE ADDRESSED

Health literacy is an important asset for adolescents to develop through engagement in schooling and curriculum. The few studies that have focused on teachers, health literacy pedagogies and assessment, show that teachers find it difficult to enhance students' critical health literacy levels and to measure students' health literacy knowledge and capabilities using valid models. The aim of this study was to develop a longer-term PD programme for secondary school teachers to enhance their ability to plan for critical health literacy learning and to co-design with teachers a curricular model for assessing health literacy.

METHODS

Two face-to-face (F2F) PD sessions and two online PD sessions were scheduled with three participating specialist Health and Physical Education (HPE) teachers, seven HPE programmes were deductively analysed using Nutbeam's health literacy hierarchy and the Australian Curriculum: HPE outcomes and content.

RESULTS

Analysis showed that interactive learning activities were dominant (64%), compared with functional (4%) and critical learning activities (4%). The co-designed curriculum model for measuring student health literacy was also developed for use in Australian schools. The resultant rubric is informed by Nutbeam's model, Broder et al.'s definition and Bloom's taxonomy.

CONCLUSION

To our knowledge, this is the first ongoing teacher PD programme that has embedded co-design processes for teachers and researchers to design a curricular health literacy assessment model for Australian and international HPE programmes. SO WHAT?: The valid measurement and assessment of child and adolescent health literacy has largely been ignored in previous research. This study is the first attempt to co-design a curricular health literacy assessment for secondary schools that can be used by teachers and health professionals.

Utilizing the CFIR framework for mapping the facilitators and barriers of implementing teachers led school mental health programs - a scoping review

BACKGROUND

Ample evidence has been generated regarding the effectiveness of school-based mental health interventions as part of the continuum of care for children and capacity building of teachers to deal with the emotional and behavioral challenges of students. The increasing trend of utilization of teachers as the natural support system of children and the huge financial impact of public health interventions highlights the need to review all available evidence regarding multilevel factors that facilitate or pose a challenge to the provision of School Mental Health Programs (SMHP) using teachers as providers. The current review aims to map extracted evidence under the Consolidated Framework for Implementation Research (CFIR) domains to support future implementation research on school-based mental health services.

METHODS

The scoping review included experimental, qualitative studies, and systematic reviews involving teacher-led mental health programs conducted in the school setting to improve the socio-emotional well-being of children and adolescents irrespective of time and geographical limitations. All (published and unpublished) evidence in English from Pubmed, Cochrane database of systematic reviews and clinical trials, Scopus, and Science Direct was searched using keywords and Boolean combinations and extracted using study designs, place of study, year of publication, sample size, and target population. A qualitative analysis of implementation facilitators and barriers cited by the studies was carried out and mapped on CFIR.

RESULTS

This review identified barriers and facilitators of implementation across school-based mental health Programs in 29 studies. The major emerging themes were those related to the inner setting of the organization, the process of implementation, and the characteristics of individuals involved in implementation. These included the availability of structural characteristics, positive school culture, organizational readiness, committed leadership, and beliefs of the providers.

CONCLUSION

Findings highlight the need for early assessment of contextual factors acting as barriers and facilitators and careful execution following realistic planning and stakeholders' engagement to ensure the success of SMHP.

School Suspension as a Predictor of Young Adult Homelessness: The International Youth Development Study

School suspension in adolescence has been shown to predict homelessness in young adulthood, suggesting that it may be a point of intervention to reduce young adult homelessness. Under zero tolerance policies, school suspension is more common in the United States relative to Australia. Multilevel modeling of cross-national longitudinal data from the International Youth Development Study tested prospective associations between adolescent problem behaviors, student-perceived likelihood of suspension/expulsion, school-level behavior management policy, and young adult homelessness. Population-based samples of participants from Washington State (United States) and Victoria (Australia) were surveyed at ages 13, 14, 15 (2002-2004), and 25 years (2014-15; n = 1945; 51% female). Over half of the young adults who reported homelessness within the previous year at age 25 had experienced school suspension. Individual-level school suspension in middle school predicted young adult homelessness. Higher levels of adolescent rebelliousness, non-violent and violent antisocial behavior, and substance use predicted a higher likelihood of school suspension at the person-level and were indirectly related to increased risk for homelessness at age 25. School behavior management policy was not related to a history of school suspension at either the person- or school-level once individual factors were controlled. Findings demonstrate the importance of school suspension as a risk factor for future homelessness and suggest that prevention programming that aims to mitigate substance use, antisocial behaviors, and school suspension may help to reduce young adult homelessness.

Evaluating a whole-school approach to addressing gender-based violence in Scottish secondary schools (Equally Safe at School): a study protocol for a type I hybrid effectiveness-implementation trial

INTRODUCTION

Equally Safe at School (ESAS) is a whole-school intervention to reduce gender-based violence (GBV) in secondary school. ESAS comprises self-assessment, student-led action group, two-tier staff training, curriculum enhancement and policy review. Schools set up key activities in Year 1 and embed them in Year 2. GBV, including sexual harassment, is common in secondary schools and disproportionately affects young women and lesbian, gay, bisexual, transgender and queer youth.

METHODS AND ANALYSIS

We will evaluate the effectiveness, cost-effectiveness, mechanisms of action and implementation of ESAS. We will recruit 36 schools across Scotland. The evaluation comprises three linked studies:Study 1: Pragmatic cluster randomised trial with 1:1 school allocation to either immediate ESAS intervention start (intervention schools) or 12-month delayed intervention start (control schools). Our primary outcome of student experience of sexual harassment will be measured at 12 months post-randomisation. Analysis of primary and secondary outcomes (student and school level) will be conducted on an intention to treat (ITT) basis comparing schools according to their original allocation.Study 2: Mixed-methods evaluation. Study 2A: Longitudinal follow-up will assess primary, secondary and intermediate outcomes at baseline, 12 months and 24 months of follow-up. Study 2B: Systems and realist-informed process evaluation will assess intervention and control school context, fidelity, dose and reach, acceptability and actor response, and how this varies by school and students. We will also assess implementation processes and mechanisms of action (beneficial or harmful), including if and how change is embedded over time, and if and how ESAS helps schools leverage other assets and resources.Study 3: Economic evaluation to assess the within-trial and longer term cost-effectiveness of ESAS.The methods include surveys in three out of six year groups (Years 2, 4 and 6) in all schools (baseline, 12 months and 24 months of follow-up); interviews with staff, students and other stakeholders; activity observations; brief surveys with key actors and analysis of trial documentation.

ETHICS AND DISSEMINATION

Ethical approval by University of Glasgow MVLS Ethics Committee (200220268). Findings will be disseminated via multiple channels to researchers, GBV and education sector stakeholders, study participants and the public.

Systematic Review and Meta-analysis of the Effectiveness of Whole-school Interventions Promoting Mental Health and Preventing Risk Behaviours in Adolescence

Adolescence is a vulnerable period for the onset of mental disorders and risk behaviours. Based on the Health-Promoting Schools Framework, whole-school interventions offer a promising strategy in this developmentally-sensitive cohort, through championing a systems-based approach to promotion and prevention that involves the key stakeholders in an adolescent's life. The evidence-base surrounding the effectiveness of whole-school interventions, however, remains inconclusive, partly due to the insufficient number of studies in previous meta-analyses. An updated systematic review and meta-analysis was thus conducted on the effectiveness of whole-school interventions promoting mental health and preventing risk behaviours in adolescence. From 12,897 search results, 28 studies reported in 58 publications were included. Study characteristics and implementation assessments were synthesized across studies, and quality appraisals and meta-analyses performed. Analyses identified a significant reduction in the odds of cyber-bullying by 25%, regular smoking by 31% and cyber-aggression by 37% in intervention participants compared to the control. Whole-school interventions thus offer substantial population health benefits through the reduction of these highly-prevalent issues affecting adolescents. The non-significant findings pertaining to the remaining eleven outcomes, including alcohol use, recreational drug use, anxiety, depression and positive mental health, are likely attributable to suboptimal translation of the Health-Promoting Schools Framework into practice and inadequate sensitivity to adolescents' local developmental needs. Given the ongoing challenges faced in the implementation and evaluation of these complex interventions, this study recommends that future evaluations assess the implementation of health-promoting activities in both intervention and control conditions and actively use this implementation data in the interpretation of evaluation findings.Preregistration: A pre-registered PROSPERO protocol (ID: CRD42023491619) informed this study.

Associations of Perceived School and Year Group Climate with Mental Health Among Children Aged 7-to-11 Years

Schools are an important setting for interventions to improve mental health. There is growing evidence that school climate - sometimes expressed as the perceptions that children have about the relationships, safety, values, and beliefs within their school - can impact child mental health. Poor child mental health is associated with feelings of distress as well deficits in functioning. However, while most studies have focused on school climate, climate at lower levels of nesting, including year group, may be important. Cross-sectional data on emotional and behavioural difficulties from 32,606 children in primary schools in Wales (ages 7-11, year groups 3-6) were collected via a school survey, delivered online and within the classroom environment to all children who consented, and analysed using multilevel modelling. Models were then extended to consider how aggregated measures of year group and school climate are associated with mental health outcomes. The unadjusted variance partition coefficients (VPCs) indicated that 2.8% of the variance in emotional difficulties and 3.2% in behavioural difficulties were attributable to differences in the year group, while school-level differences represented 2.4% and 3.5%, respectively. More positive year group and school climate were associated with more positive mental health outcomes. School and year group climate are independently associated with primary school children's mental health. Interventions to support mental health should aim to optimise the whole school climate, as well as climate within year group clusters.

Public engagement to refine a whole-school intervention to promote adolescent mental health

Background

Despite high rates of adolescent mental health problems, there are few effective school-based interventions to address this. Whole-school interventions offer a feasible and sustainable means of promoting mental health, but few have to date been evaluated. Previously we trialled the Learning Together intervention comprising local needs assessment, student and staff participation in decision-making, restorative practice, and a social and emotional skills curriculum. This was effective not only in preventing bullying (primary outcome), but also in promoting mental well-being and psychological functioning (secondary outcomes).

Objective

We aimed to adapt Learning Together to develop Learning Together for Mental Health, focused on promoting mental health. This paper reports on how we refined and elaborated intervention materials to produce the Learning Together for Mental Health intervention including through patient and public involvement and engagement.

Design

We reviewed evidence to inform choice of the curriculum component and the contents of our needs assessment survey. We conducted patient and public involvement and engagement with school staff and students, and children and young people from the National Children's Bureau to adapt the intervention. We also conducted a systematic review of reviews to inform a menu of evidence-based actions, but this is reported separately.

Setting

Southern England.

Participants

Patient and public involvement and engagement was conducted with four staff and five students from one secondary school, and a group of two school senior leadership team members from different schools, and about eight children and young people who were members of the Young National Children's Bureau.

Interventions

None.

Results

We refined and elaborated our initial plans for Learning Together for Mental Health to generate an intervention supported by full materials, training and external facilitation. We focused needs assessment on mental health, added a menu of evidence-based whole-school mental health actions, and switched to a different social and emotional skills curriculum. We retained restorative practice and staff/student involvement in decisions. No further refinements were made to the intervention theory of change or overall approach. Patient and public involvement and engagement was useful, but not all suggestions were acted on either because some participants suggested dropping pre-determined elements (e.g. needs survey) or because suggestions (e.g. to include aromatherapy) lacked evidence of effectiveness.

Limitations

Not all of our engagements with patient and public involvement and engagement stakeholders were sustained over time. Our patient and public involvement and engagement work was affected by its having occurred within the recovery period from COVID-19 when schools were more stressed than normal. We had planned for the school involved in patient and public involvement and engagement to be above average in student free-school-meals eligibility, but the school initially recruited dropped out at the last minute. Its replacement had a lower-than-average rate of free-school-meal entitlement.

Conclusions

This paper reports on the process of adaptation and reflects on the various ways in which engagement and evidence review were useful in this process. We found that it is possible to refine interventions and elaborate them to provide full materials and support via processes drawing on evidence review and patient and public involvement and engagement. The latter proved valuable in informing refinement of Learning Together for Mental Health in terms of ensuring its feasibility, acceptability, and inclusiveness. However, in our opinion, not all suggestions from patient and public involvement and engagement can or should be acted on, especially when they do not align with the evidence base.

Future work

A feasibility study to optimise the intervention and assess whether progression to a full trial is justified.

Qualitative study of the feasibility and acceptability of implementation, and potential mechanisms of Learning Together for Mental Health, a whole-school intervention aiming to promote mental health and wellbeing in secondary schools

BACKGROUND

Despite high rates of adolescent mental-health problems, there are few effective whole-school interventions to address this. Whole-school interventions offer a feasible and sustainable means of promoting mental health. We previously evaluated the Learning Together (LT) intervention which was effective in preventing bullying (primary outcome), promoting mental well-being, psychological functioning, and reducing substance use (secondary outcomes). We adapted LT to develop Learning Together for Mental Health (LTMH) with a new menu of evidence-based actions to address mental health and an enhanced SEL curriculum.

METHODS

We undertook a feasibility study of LTMH, a whole-school intervention featuring needs assessment, student and staff participation in decision-making via action groups selecting actions from an evidence-based menu, restorative practice, and a SEL and resilience skills curriculum between 2022 and 2023. This article examines the feasibility, acceptability, and potential mechanisms of LTMH, qualitatively, drawing on interviews and focus groups with 49 students in years 8 and 10, and 20 staff across four state secondary schools in southern England.

RESULTS

The intervention was feasible and acceptable to implement. In terms of feasibility, the SEL curriculum was the most challenging to implement and was not prioritised by schools that had existing social and emotional learning lessons. Training and external facilitation were well-rated. Some schools struggled with the resourcing and workload implications of implementing actions from the evidence-based menu. Some aspects were not clear. Some staff were not aware that the various components worked together. Needs reports were not easy to understand for all. Students were generally supportive of restorative practice and SEL lessons. Data supported a potential mechanism involving increased school belonging and developing practical knowledge and skills to manage emotions and relationships. The intervention has little potential for harm.

CONCLUSIONS

The intervention is ready for phase III trial with minor adaptations. A phase III trial of effectiveness is justified.

Relationship between physical exercise, bullying, and being bullied among junior high school students: the multiple mediating effects of emotional management and interpersonal relationship distress

OBJECTIVE

This paper investigates the relationships between physical activity (PA), school bullying, emotion regulation self-efficacy (ERS), and interpersonal relationship distress (IRD) among junior high school students. It also examines the underlying mechanisms of school bullying to provide insights into reducing adolescent bullying and to lay the groundwork for preventing and controlling aggressive behaviors.

METHODS

A survey was conducted on 484 students (240 males, 12.18 ± 0.8 years) from 4 secondary schools using the Physical Activity Rating Scale (PARS), Emotional Management Self-Efficacy Scale (EMSS), Interpersonal Relationship Distress Scale (IRDS), and Campus Bullying Scale (CBS) to examine the effects among the variables. A stratified random sampling method was used to select the sample, and data were collected with a structured questionnaire. The data were analyzed using SPSS 24.0 and AMOS 24.0 statistical software. The analysis included Pearson correlation analysis, structural equation modeling, and bias-corrected percentile Bootstrap methods.

RESULTS

(1) PA negatively predicts IRD, which in turn has an indirect effect on bullying (PA → IRD → Bullying), ES = -0.063. Additionally, EM and IRD act as mediators between PA and school bullying (PA → EM → IRD → Bullying), ES = 0.025. (2) PA negatively predicts IRD, which has an indirect effect on being bullied (PA → IRD → Being bullied), ES = -0.044. EM and IRD serve as chain mediators between PA and being bullied (PA → EM → IRD → Being bullied), ES = -0.071.

CONCLUSION

PA can positively predict bullying, but it can be mitigated through EM to reduce IRD, thereby decreasing the occurrence of campus bullying and being bullied.

'Walk Buds': A walking intervention to increase physical activity, physical fitness, and emotional wellbeing, in 9-13 year old children with intellectual disabilities. Results of a clustered randomised feasibility trial

BACKGROUND

Children with intellectual disability are less physically active and more sedentary than typically developing peers. To date no studies have tested the feasibility of a school-based walking intervention for children with Intellectual Disability.

METHOD

A clustered randomised controlled trial (cRCT), with an embedded process evaluation, was used to test the feasibility of a school-based walking intervention. Eight schools (n = 161 pupils aged 9-13 years) were randomised into either an intervention arm or an 'exercise as usual' arm. Measures included physical activity, physical fitness and emotional wellbeing. Baseline and 3-month follow-up data were collected.

RESULTS

The 'Walk Buds' intervention was found to be acceptable to teaching staff and pupils, with an uptake rate of the walking sessions offered of 84%.

CONCLUSION

A number of challenges were experienced, relating to the COVID-19 pandemic, and difficulties collecting accelerometer data. Barriers, facilitators and required changes identified through the mixed methods process evaluation are discussed.

Antibullying Interventions in Schools: Assessing the Evidence Base

OBJECTIVE

This systematic review used established rating criteria to describe the level of evidence for interventions aimed at preventing or reducing bullying perpetration and victimization in schools, synthesized the evidence for students from racially and ethnically diverse backgrounds, and reviewed the literature for available information to conduct an economic analysis of the interventions.

METHODS

Major databases, gray literature, and evidence-base registries were searched to identify studies published from 2008 through 2022. The authors rated antibullying intervention models as having high, moderate, or low evidence depending on the number and rigor of studies with positive findings.

RESULTS

Overall, 80 articles reporting on 71 original research studies describing a total of 48 antibullying interventions met the inclusion criteria for this review. Two schoolwide interventions received a high-evidence rating: the KiVa (Kiusaamista Vastaan) Antibullying Program and the Friendly Schools program. Multilevel interventions with components at the levels of school, classroom, and individual student most consistently showed strong evidence for reducing bullying behavior in elementary and middle school grades. Four interventions yielded positive effects in reducing bullying and victimization among diverse samples of students.

CONCLUSIONS

Antibullying interventions can reduce bullying in schools. Some interventions show effectiveness with students from racially and ethnically diverse backgrounds. The gains relative to per-student costs were in the range that is considered cost-effective. Most implementation costs are spent on staff training and support. Research on successful implementation of whole-school interventions and additional synthesis of evidence pertaining to program structures would further advance the antibullying evidence base.

How do schools influence the emotional and behavioural health of their pupils? A multi-level analysis of 135 schools in the Born in Bradford inner city multi-ethnic birth cohort

PURPOSE

To estimate variation in emotional and behavioural problems between primary schools in Bradford, an ethnically diverse and relatively deprived city in the UK.

METHODS

We did a cross-sectional analysis of data collected from 2017 to 2021 as part of the 'Born In Bradford' birth cohort study. We used multilevel linear regression in which the dependent variable was the Strengths and Difficulties Questionnaire (SDQ) total score, with a random intercept for schools. We adjusted for pupil-level characteristics including age, ethnicity, socioeconomic status, and parental mental health.

RESULTS

The study included 5,036 participants from 135 schools. Participants were aged 7-11 years and 56% were of Pakistani heritage. The mean SDQ score was 8.84 out of a maximum 40. We estimated that the standard deviation in school-level scores was 1.41 (95% CI 1.11-1.74) and 5.49% (95% CI 3.19-9.37%) of variation was explained at school level. After adjusting for pupil characteristics, the standard deviation of school-level scores was 1.04 (95% CI 0.76-1.32) and 3.51% (95% CI 1.75-6.18%) of variation was explained at school level. Simulation suggested that a primary school with 396 pupils at the middle of the distribution has 63 pupils (95% CI 49-78) with a 'raised' SDQ score of 15 + /40; and shifting a school from the lower to the upper quartile would prevent 26 cases (95% CI 5-46).

CONCLUSION

The prevalence of emotional and behavioural problems varies between schools. This is partially explained by pupil characteristics; though residual variation in adjusted scores may suggest that schools have a differential impact on mental wellbeing.

Sedentary Behavior and School Bullying in Adolescents: An Analysis Based on a National Survey in Colombia

BACKGROUND

Sedentarism has been associated with poorer mental health, greater likelihood of bullying and suicide risk; however, studies with national coverage are needed to characterize contexts and allow comparisons between nations. The aim of this study was to examine the association between sedentary lifestyles with bullying in the social context of Colombian adolescents.

METHODS

Cross-sectional study with 78,772 adolescents aged 13-17 years participating in the 2017 National School Health Survey. Sedentary behavior was defined as sitting for 3+ hours/day of leisure time, while bullying was identified by self-report of being victimized 1+ times/month. Relative frequencies were estimated and, using a log-binomial regression model, prevalence ratios (PR) were calculated.

RESULTS

A total of 15.31% of students reported being victims of bullying. A higher probability to be bullied was estimated in sedentary adolescents (PR: 1.18; 95% CI: 1.09-1.29), as well as in females, ethnic minorities, those who went hungry in the last month due to lack of food, students with health problems, and private schools.

CONCLUSIONS

Bullying was related with sedentary leisure time, gender, ethnicity, type of educational institution, and presence of health problems. Being a multicausal phenomenon, bullying demands policies and programs with a greater focus on the most vulnerable groups.

Trends in adolescent emotional problems in Wales between 2013 and 2019: the contribution of peer relationships

BACKGROUND

Epidemiological evidence shows a substantial increase in adolescent emotional problems in many countries, but reasons for this increase remain poorly understood. We tested change in emotional problems in a national sample of young people in Wales in 2013, 2017 and 2019 using identical symptom screens, and examined whether trends were accounted for by changes in youth friendship quality and bullying.

METHODS

The present study of 230,735 11-16-year olds draws on repeat cross-sectional data obtained on three occasions (2013, 2017 and 2019) in national school-based surveys in Wales (conducted by the School Health Research Network). Emotional problems were assessed with a brief validated symptom screen (the SCL-4).

RESULTS

There was a significant increase in emotional problem scores between 2013 and 2019 (b[95% CI] = 1.573 [1.380, 1.765]). This increase was observed for all ages and was more pronounced for girls than boys (interaction b [95% CI] = 0.229 [0.004, 0.462]) and for young people from less affluent families (interaction b [95% CI] = -0.564[-0.809, -0.319]). Of the total sample, 14.2% and 5.7% reported frequent face-to-face and cyberbullying respectively. There were modest decreases in friendship quality and increases in rates of bullying between 2013 and 2019, but accounting for these changes did not attenuate estimates of the population-level increase in emotional problems.

CONCLUSIONS

This study provides evidence of a substantial increase in emotional problems among young people in Wales, particularly for young people from less affluent backgrounds. Changes in bullying or friendship quality did not explain this increase.

School Connectedness and Adolescent E-cigarette Susceptibility in an Urban Sample of Middle and High School Students

Adolescent school connectedness generally protects from risk behaviors such as tobacco use; however, its relationship to e-cigarette use is unclear. This study examines the relationship between adolescent school connectedness and e-cigarette susceptibility in a diverse longitudinal sample. This secondary analysis of a school-based intervention surveyed 608 middle (66%) and high school (34%) students from 10 schools at 3 time points over 1 year. At baseline, respondents had a mean age of 14 years, 54% were female, and 71% were BIPOC (Black, Indigenous, People of Color). Logistic regression models examined unadjusted and adjusted associations between school connectedness (both baseline and concurrent) and e-cigarette susceptibility over time. E-cigarettes represented the most prevalent form of current nicotine-containing product use in spring 2019 (2.3%), and most respondents reported no e-cigarette susceptibility (69%). E-cigarette susceptibility remained relatively stable during the study. Higher baseline school connectedness levels were associated with lower odds of e-cigarette susceptibility over time. Similarly, higher concurrent school connectedness scores were associated with lower odds of e-cigarette susceptibility over time: spring 2019 (OR, 0.39; 95% CI, 0.32, 0.47), fall 2019 (OR, 0.49; 95% CI, 0.34, 0.72), and spring 2020 (OR, 0.64; 95% CI, 0.47, 0.87). Findings were similar for middle and high school students and did not differ significantly after adjusting for other covariates. Adolescents' school connectedness appears to protect from e-cigarette susceptibility over time, underscoring the importance of promoting positive school experiences to reduce adolescent risk e-cigarette use.

Violence outcomes in later adolescence with the Good School Toolkit-Primary: a nonrandomized controlled trial in Uganda

BACKGROUND

We sought to determine whether the Good School Toolkit-Primary violence prevention intervention was associated with reduced victimisation and perpetration of peer and intimate partner violence four years later, and if any associations were moderated by sex and early adolescent: family connectedness, socio-economic status, and experience of violence outside of school.

METHODS

Drawing on schools involved in a randomised controlled trial of the intervention, we used a quasi-experimental design to compare violence outcomes between those who received the intervention during our trial (n = 1388), and those who did not receive the intervention during or after the trial (n = 522). Data were collected in 2014 (mean age 13.4, SD 1.5 years) from participants in 42 schools in Luwero District, Uganda, and 2018/19 from the same participants both in and out of school (mean age 18, SD: 1.77 years). We compared children who received the Good School Toolkit-Primary, a whole school violence prevention intervention, during a randomised controlled trial, to those who did not receive the intervention during or after the trial. Outcomes were measured using items adapted from the International Society for the Prevention of Child Abuse and Neglect Child Abuse Screening Tool-Child Institutional. We used mixed-effect multivariable logistic regression, with school fitted as a random-effect to account for clustering.

RESULTS

1910 adolescents aged about 16-19 years old were included in our analysis. We found no evidence of an average long-term intervention effect on our primary outcome, peer violence victimization at follow-up (aOR = 0.81, 95%CI = 0.59-1.11); or for any secondary outcome. However, exposure to the intervention was associated with: later reductions in peer violence, for adolescents with high family connectedness (aOR = 0.70, 95% CI 0.49 to 0.99), but not for those with low family connectedness (aOR = 1.07, 95% CI 0.69 to 1.6; p-interaction = 0.06); and reduced later intimate partner violence perpetration among males with high socio-economic status (aOR = 0.32, 95%CI 0.11 to 0.90), but not low socio-economic status (aOR = 1.01 95%CI 0.37 to 2.76, p-interaction = 0.05).

CONCLUSIONS

Young adolescents in connected families and with higher socio-economic status may be better equipped to transfer violence prevention skills from primary school to new relationships as they get older.

The Social and Emotional Education and Development intervention to address wellbeing in primary school age children: the SEED cluster RCT

Background

Stronger social and emotional well-being during primary school is positively associated with the health and educational outcomes of young people. However, there is little evidence on which programmes are the most effective for improving social and emotional well-being.

Objective

The objective was to rigorously evaluate the Social and Emotional Education and Development (SEED) intervention process for improving pupils' social and emotional well-being.

Design

This was a stratified cluster randomised controlled trial with embedded process and economic evaluations. Thirty-eight primary schools were randomly assigned to the SEED intervention or to the control group. Hierarchical regression analysis allowing for clustering at school learning community level was conducted in R (statistical package).

Setting

The SEED intervention is a whole-school intervention; it involved all school staff and two cohorts of pupils, one starting at 4 or 5 years of age and the second starting at 8 or 9 years of age, across all 38 schools.

Participants

A total of 2639 pupils in Scotland.

Intervention

The SEED intervention used an iterative process that involved three components to facilitate selection and implementation of school-based actions: (1) questionnaire completion, (2) benchmarked feedback to all staff and (3) reflective discussions (all staff and an educational psychologist).

Main outcome measure

The primary outcome was pupils' Strengths and Difficulties Questionnaire-Total Difficulties Score when pupils were 4 years older than at baseline.

Results

The primary outcome, pupils' Strengths and Difficulties Questionnaire-Total Difficulties Score at follow-up 3, showed improvements for intervention arm pupils, compared with those in the control arm [relative risk -1.30 (95% confidence interval -1.87 to -0.73), standardised effect size -0.27 (95% confidence interval -0.39 to -0.15)]. There was no evidence of intervention effects according to deprivation: the results were significant for both affluent and deprived pupils. Subgroup analysis showed that all effect sizes were larger for the older cohort, particularly boys [relative risk -2.36 (95% confidence interval -3.62 to -1.11), standardised effect size -0.42 (95% confidence interval -0.64 to -0.20)]. Although there was no statistically significant difference in incremental cost and quality-adjusted life-years, the probability that the intervention is cost-effective at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year was high, at 88%. Particularly valued mechanisms of the SEED intervention were its provision of time to reflect on and discuss social and emotional well-being and its contribution to a culture of evaluating practice.

Limitations

It was a challenge to retain schools over five waves of data collection.

Conclusions

This trial demonstrated that the SEED intervention is an acceptable, cost-effective way to modestly improve pupil well-being and improve school climate, particularly for older boys and those with greater levels of psychological difficulties. It was beneficial during the transition from primary to secondary school, but this diminished after 6 years. The SEED intervention can be implemented alongside existing systems for addressing pupil well-being and can be complementary to other interventions.

Future work

Assess whether or not the SEED intervention has a beneficial impact on academic attainment, is transferable to other countries and other organisational settings, would be strengthened by adding core training elements to the intervention process and is transferable to secondary schools. Understand the gender differences illustrated by the outcomes of this trial. Conduct further statistical research on how to handle missing data in longitudinal studies of complex social interventions.

Development of a school-based programme for mental health promotion and prevention among adolescents in Nepal and South Africa

Introduction

Adolescence is a critical time for mental health promotion and prevention and establishing healthy behaviours. Implementing universal, school-based psychosocial interventions can improve short- and long-term health trajectories for adolescents. While these interventions may offer important opportunities for fostering skills and relationships, few school-based interventions have been developed for and tested in low- and middle-income countries (LMICs) where adolescent mental health needs may be significant and under-served. This manuscript details the development of a multi-component, universal school-based intervention, Health Action in ScHools for a Thriving Adolescent Generation (HASHTAG), for adolescents aged 12-15 years in Nepal and South Africa.

Methods and results

We describe HASHTAG's development over four phases, combining methods and results as each phase was iteratively conducted between 2018 and 2021. Phase 1 included a systematic review and components analysis, building from WHO guidelines for adolescent mental health. Seven components were strongly supported by the evidence: emotional regulation, stress management, mindfulness, problem-solving, interpersonal skills, assertiveness training, and alcohol and drug education. Phase 2 encompassed site selection, theory of change development, and formative research engagements; research teams in each site engaged adolescents and key adult stakeholders to identify priorities for intervention. Stakeholders voiced preferences for external facilitators and key content and delivery for intervention sessions. These findings informed Phase 3, a draft manual of HASHTAG, including a whole-school component, called Thriving Environment in Schools, and a classroom-based, six-session component, Thrive Together. In Phase 4, participants engaged in consultative workshops to review and contextualise content by country, preparing HASHTAG for implementation in a feasibility trial. Minor adaptations were made in Nepal, including using school nurses and adjusting take-home materials; both country's workshops identified practical considerations for implementing activities.

Conclusions

HASHTAG was designed around core evidence-based components to increase translatability across LMICs, while enabling country-specific tailoring to enhance feasibility. Future research will test whether this multi-component, whole-school approach can improve adolescent mental health.

Statistical analyses of ordinal outcomes in randomised controlled trials: a scoping review

BACKGROUND

Randomised controlled trials (RCTs) aim to estimate the causal effect of one or more interventions relative to a control. One type of outcome that can be of interest in an RCT is an ordinal outcome, which is useful to answer clinical questions regarding complex and evolving patient states. The target parameter of interest for an ordinal outcome depends on the research question and the assumptions the analyst is willing to make. This review aimed to provide an overview of how ordinal outcomes have been used and analysed in RCTs.

METHODS

The review included RCTs with an ordinal primary or secondary outcome published between 2017 and 2022 in four highly ranked medical journals (the British Medical Journal, New England Journal of Medicine, The Lancet, and the Journal of the American Medical Association) identified through PubMed. Details regarding the study setting, design, the target parameter, and statistical methods used to analyse the ordinal outcome were extracted.

RESULTS

The search identified 309 studies, of which 144 were eligible for inclusion. The most used target parameter was an odds ratio, reported in 78 (54%) studies. The ordinal outcome was dichotomised for analysis in 47 ( 33 % ) studies, and the most common statistical model used to analyse the ordinal outcome on the full ordinal scale was the proportional odds model (64 [ 44 % ] studies). Notably, 86 (60%) studies did not explicitly check or describe the robustness of the assumptions for the statistical method(s) used.

CONCLUSIONS

The results of this review indicate that in RCTs that use an ordinal outcome, there is variation in the target parameter and the analytical approaches used, with many dichotomising the ordinal outcome. Few studies provided assurance regarding the appropriateness of the assumptions and methods used to analyse the ordinal outcome. More guidance is needed to improve the transparent reporting of the analysis of ordinal outcomes in future trials.

Bullying fosters interpersonal distrust and degrades adolescent mental health as predicted by Social Safety Theory

Social Safety Theory predicts that socially threatening experiences such as bullying degrade mental health partly by fostering the belief that others cannot be trusted. Here we tested this prediction by examining how peer bullying in childhood impacted adolescent mental health, and whether this effect was mediated by interpersonal distrust and several other commonly studied mediators-namely diet, sleep and physical activity-in 10,000 youth drawn from the UK's Millennium Cohort Study. Youth bullied in childhood developed more internalizing, externalizing and total mental health problems in late adolescence, and this effect was partially mediated by interpersonal distrust during middle adolescence. Indeed, adolescents who developed greater distrust were approximately 3.5 times more likely to subsequently experience clinically significant mental health problems than those who developed less distrust. Individual and school-based interventions aimed at reducing the negative impact of bullying on mental health may thus benefit from bolstering youths' sense of trust in others.

School climate and school identification as determinants of smoking conventional cigarettes or vaping among adolescents in China: Stress-coping mediation mechanisms

INTRODUCTION

Smoking conventional cigarettes or vaping (SV) poses significant health threats to adolescents. School climate and school identification are key elements of the school environment and potential factors of SV. Based on the Stress Coping Theory, the mediations between school climate/school identification and SV, via perceived stress/active coping, were examined.

METHODS

A cross-sectional survey was conducted among secondary school students from February to March 2022 in Taizhou, China. Structural equation modeling was used.

RESULTS

The prevalence of SV among the 7526 participants was 4.7% (singular use of conventional cigarettes: 3.2%; singular use of electronic cigarettes: 3.6%; dual use: 2.1%). School climate, school identification, and active coping were positively, and perceived stress (family stress, academic stress, and peer-related stress) were negatively associated with SV. The association between school climate and SV was fully mediated via: 1) school climate → perceived stress → SV; 2) school climate → active coping → SV; and 3) school climate → perceived stress → active coping → SV. The effect sizes were 52.1%, 43.8%, and 6.3%, respectively. Similar partial mediation mechanisms were found between school identification and SV, with relatively small effect sizes (<10%).

CONCLUSIONS

This study observed the prevalence of SV among Chinese secondary school students. School climate and school identification had both significant direct and indirect (via perceived stress/active coping) effects on SV. Positive school environments may reduce students' stress and promote active coping. The stress coping mechanisms explained the association between school climate and SV better than between school identification and SV.

School-based interventions TO Prevent Dating and Relationship Violence and Gender-Based Violence: STOP-DRV-GBV systematic review

Background

Schools have a duty of care to prevent violence between students but a significant amount of dating and relationship violence and gender-based violence occurs in schools. These are important public health issues with important longitudinal consequences for young people.

Objectives

To understand functioning and effectiveness of school-based interventions for the prevention of dating and relationship violence and gender-based violence.

Review methods

We undertook a mixed-methods systematic review to synthesise different types of evidence relating to school-based interventions for the prevention of dating and relationship violence and gender-based violence to understand if, how and in what ways these interventions are effective. We searched 21 databases and 2 trial registers and undertook forwards and backwards citation chasing, author contact and other supplementary search methods. Searches identified all literature published to June 2021. All screening was undertaken in duplicate and independently, and we quality appraised all included studies.

Results

We included 247 reports (68 outcome evaluations, 137 process evaluations). Synthesis of intervention components produced an intervention typology: single-component, curricular, multicomponent, and multilevel programmes. Synthesis of intervention theories suggested that interventions aiming to increase students' sense of school belonging and sense of safety in the school building could encourage increased learning of prosocial skills and increased prosocial peer norms, and so potentially reducing dating and relationship violence and gender-based violence. Synthesis of factors affecting delivery highlighted school organisation and leaders who believed in the importance of addressing dating and relationship violence/gender-based violence, along with time and resources to deliver the interventions. The ease with which the intervention could be delivered and modified was also important. Meta-analysis found stronger evidence for intervention effectiveness in reducing dating and relationship violence than for gender-based violence, with significant long-term impacts on dating and relationship violence victimisation and perpetration, and some evidence that interventions in high-income countries could be effective for reducing victimisation and perpetration of gender-based violence in the long-term. Impacts on knowledge and attitudes were primarily short-term. Network meta-analysis did not suggest superiority of any intervention type. Moderation evidence suggested interventions reduced dating and relationship violence perpetration in boys more than girls, but reduced gender-based violence perpetration more in girls. Metaregression by intervention component did not explain heterogeneity in effectiveness, but qualitative comparative analysis suggested that reducing perpetration was important to reducing victimisation, and that perpetration could be reduced via focus on interpersonal skills, guided practice and (for gender-based violence) implementation of social structural components.

Limitations

Despite an exhaustive search, trials may have been missed and risk of publication bias was high for several analyses.

Conclusions

This is the most comprehensive systematic review of school-based interventions for dating and relationship violence and gender-based violence to date. It is clear that the prevention of dating and relationship violence and gender-based violence in schools will require longer-term investment to show benefit.

Future work

Future research is needed to understand why intervention effectiveness appears stronger for dating and relationship violence than gender-based violence.

Whole-school interventions promoting student commitment to school to prevent substance use and violence, and improve educational attainment: a systematic review

Background

Whole-school interventions modify the school environment to promote health. A subset of these interventions promotes student commitment to school to prevent substance (tobacco, alcohol, other drugs) use and/or violence. A previous review identified the theory of human functioning and school organisation as a comprehensive theory of such interventions, and found evidence that these interventions reduce substance use and/or violence.

Objectives

The objectives were to search for, appraise and synthesise evidence to address the following questions: (1) What whole-school interventions promoting student commitment to school to prevent substance use and/or violence have been evaluated, what intervention subtypes are apparent and how closely do these align with the theory of human functioning and school organisation? (2) What factors relating to setting, population and intervention affect implementation? (3) What are the effects on student substance use, violence and educational attainment? (4) What is the cost-effectiveness of such interventions? (5) Are intervention effects mediated by student commitment to school or moderated by setting or population?

Data sources

A total of 56 information sources were searched (in January 2020), then an updated search of 48 of these was carried out (in May 2021). Reference lists were also searched and experts were contacted.

Review methods

Eligible studies were process/outcome evaluations of whole-school interventions to reduce student violence or substance use among students aged 5-18 years attending schools, via actions aligning with the theory of human functioning and school organisation: modifying teaching to increase engagement, enhancing student-staff relationships, revising school policies, encouraging volunteering or increasing parental involvement. Data extraction and quality assessments used existing tools. Theory and process reports were synthesised qualitatively. Outcome and economic data were synthesised narratively; outcome data were meta-analysed.

Results

Searches retrieved 63 eligible reports on 27 studies of 22 interventions. We identified four intervention subtypes focused on student participation in school-wide decisions, improving staff-student relationships, increasing engagement in learning and involving parents. The theories of change of most intervention subtypes aligned closely with the theory of human functioning and school organisation, and informed refinement of an intervention theory of change. Theories of change for interventions increasing learning engagement did not align with this theory, aiming instead to increase school commitment primarily via social skills curricula. Factors influencing the implementation included whether or not interventions were tailorable, workable and well explained. Interventions with action groups comprising staff/students, etc. and providing local data were well implemented. Implementation was also affected by whether or not schools accepted the need for change and staff had the resources for delivery. Meta-analyses suggest small, but significant, intervention effects in preventing violence victimisation and perpetration, and substance use. There was sparse and inconsistent evidence of moderation and some evidence of mediation by student commitment to school. Two economic evaluations suggested that there is the potential for the interventions to be cost-effective.

Limitations

The quality of the studies was variable and the economic synthesis was limited to two studies.

Conclusions

Whole-school interventions aiming to promote student commitment to school share similar theories of change and factors affecting implementation. They have the potential to contribute to preventing violence and substance use among young people. Future trials should aim to optimise intervention effectiveness by better theorisation, and assess implementation and effect moderators and mediators.

An Analysis of the Association between School Bullying Prevention and Control Measures and Secondary School Students' Bullying Behavior in Jiangsu Province

(1) Background: China released regulations on school bullying prevention and control in 2017; however, current research on school bullying in China focuses on exploring influencing factors and lacks empirical research on the effectiveness of anti-bullying policies in schools. The objective of this study was to use an empirical model to explore the association between bullying prevention and control measures and secondary school students' bullying victimization and multiple bullying victimization in Chinese schools. (2) Methods: Data were derived from the 2019 Surveillance of Common Diseases and Health Influencing Factors among Students in Jiangsu Province. The school's bullying prevention and control measures, which was the independent variable, were obtained in the form of a self-report questionnaire and consisted of five measures: the establishment of bullying governance committees, thematic education for students, thematic training for parents, special investigations on bullying, and a bullying disposal process. Bullying victimization and multiple bullying victimization, which was the dependent variable, were obtained through a modified version of the Olweus bullying victimization questionnaire. In order to better explain the differences in the results, this study constructed multilevel logistic regression models to test the association between school bullying prevention and control measures and the rates of bullying victimization and multiple bullying victimization among secondary school students at both the school level and the student level. Meanwhile, this study constructed five models based on the null model by sequentially incorporating demographic variables, physical and mental health variables, lifestyle variables, and bullying prevention and control measures in schools to verify this association. (3) Results: A total of 25,739 students were included in the analysis. The range of bullying victimization rates for students in the different secondary schools in this study was between 6.8% and 37.3%, and the range of multiple bullying victimization rates was between 0.9% and 14.8%. The establishment of bullying disposal procedures was strongly associated with a reduction in bullying victimization (OR = 0.83, 95%CI: 0.71-0.99, p < 0.05). Establishing bullying disposal procedures was not significantly associated with multiple bullying victimization rates (OR = 0.89, 95%CI: 0.73-1.09, p > 0.05). The establishment of a bullying governance committee, thematic education for students, thematic training for parents, and special surveys on bullying were not significantly associated with bullying victimization rates or multiple bullying victimization rates (all p > 0.05). (4) Conclusions: Among the current bullying prevention and control measures for secondary school students in China, the establishment of a bullying disposal process was conducive to reducing the rate of bullying victimization, but it was ineffective in reducing the rate of multiple bullying victimization, and the other preventive and control measures did not achieve the purpose of anti-bullying in schools.

The association between academic pressure and adolescent mental health problems: A systematic review

BACKGROUND

Academic pressure is a potential contributor to adolescent mental health problems, but international evidence on this association has never been synthesised.

METHODS

We conducted the first systematic review of the association between academic pressure and adolescent depression, anxiety, self-harm, suicidality, suicide attempts and suicide. We searched MEDLINE, PsycINFO, ERIC and Web of Science (core collection) up to November 24, 2022, for studies of school-going children or adolescents, which measured academic pressure or timing within the school year as the exposure and depression, anxiety, self-harm, or suicidal ideation, attempts or suicide as outcomes. Risk of bias was assessed using the Mixed Methods Appraisal Tool. We used narrative synthesis to summarise the evidence. The review was prospectively registered with PROSPERO (CRD42021232702).

RESULTS

We included 52 studies. Most studies assessed mixed anxiety and depressive symptoms (n = 20) or depressive symptoms (n = 19). Forty-eight studies found evidence of a positive association between academic pressure or timing within the school year and at least one mental health outcome.

LIMITATIONS

Most studies were cross-sectional (n = 39), adjusted for a narrow range of confounders or had other limitations which limited the strength of causal inferences.

CONCLUSIONS

We found evidence that academic pressure is a potential candidate for public health interventions which could prevent adolescent mental health problems. Large population-based cohort studies are needed to investigate whether academic pressure is a causal risk factor that should be targeted in school- and policy-based interventions.

Pattern of lifestyle behaviors and associated risk of being bullied at schools: A latent class analysis of 25,379 adolescents in Jiangsu Province of China

School bullying is a worldwide problem. Although previous studies examined the association between different lifestyle behaviors and bullying victimization, the complex co-occurrence of these behaviors was not identified, and their association with the risk of being bullied remains unclear. We aimed to identify the behavioral patterns of adolescents and to explore their association with bullying victimization. This cross-sectional study employed data from the "Surveillance for Common Diseases and Health Risk Factors among Students" project implemented in Jiangsu Province of China in 2019, and a total of 25,379 school-enrolled students were included. We used a latent class analysis to identify behavioral patterns and a regression mixture model to explore various demographic characteristics, such as age, sex, and family structure in relation to bullying victimization across different patterns. We considered respondents having targeted behaviors, including smoking, alcohol consumption, illicit drug use, sugar consumption, no fruit consumption, low physical activity, electronic media use, and insufficient sleep. Four behavioral patterns were identified, including the "adolescents without apparent targeted behaviors" (19.65%), "substance and electronic media users" (12.76%), "typical electronic media users" (54.49%), and "typical substance users" (8.10%). The risk of being bullied was the highest in the "substance and electronic media users" (probability: 0.33), tripled that in "adolescents without apparent targeted behaviors" (odds ratio: 3.60, 95% confidence interval: 3.01-4.30). Risk of being bullied was reduced for those "substance and electronic media users" living with a nuclear family. Behavioral patterns and their association with being bullied differ between groups of school-aged adolescents. To better inform decision-making based on the current real-world findings, the implementation of bullying prevention programs could target specific behavioral patterns.

Protocol to evaluate the effectiveness and cost-effectiveness of an environmental nutrition and physical activity intervention in nurseries (Nutrition and Physical Activity Self Assessment for Child Care - NAP SACC UK): a multicentre cluster randomised controlled trial

BACKGROUND

One in seven UK children have obesity when starting school, with higher prevalence associated with deprivation. Most pre-school children do not meet UK recommendations for physical activity and nutrition. Formal childcare settings provide opportunities to deliver interventions to improve nutritional quality and physical activity to the majority of 3-4-year-olds. The nutrition and physical activity self-assessment for childcare (NAP SACC) intervention has demonstrated effectiveness in the USA with high acceptability in the UK. The study aims to evaluate the effectiveness and cost-effectiveness of the NAP SACC UK intervention to increase physical activity, reduce sedentary time and improve nutritional intake.

METHODS

Multi-centre cluster RCT with process and economic evaluation. Participants are children aged 2 years or over, attending UK early years settings (nurseries) for ≥ 12 h/week or ≥ 15 h/week during term time and their parents, and staff at participating nurseries. The 12-month intervention involves nursery managers working with a Partner (public health practitioner) to self-assess policies and practices relating to physical activity and nutrition; nursery staff attending one physical activity and one nutrition training workshop and setting goals to be achieved within 6 months. The Partner provides support and reviews progress. Nursery staff receive a further workshop and new goals are set, with Partner support for a further 6 months. The comparator is usual practice. Up to 56 nurseries will be stratified by area and randomly allocated to intervention or comparator arm with minimisation of differences in level of deprivation.

PRIMARY OUTCOMES

accelerometer-assessed mean total activity time on nursery days and average total energy (kcal) intake per eating occasion of lunch and morning/afternoon snacks consumed within nurseries.

SECONDARY OUTCOMES

accelerometer-assessed mean daily minutes of moderate-to-vigorous physical activity and sedentary time per nursery day, total physical activity on nursery days compared to non-nursery days, average serving size of lunch and morning/afternoon snacks in nursery per day, average percentage of core and non-core food in lunch and morning/afternoon snacks, zBMI, proportion of children who are overweight/obese and child quality-of-life. A process evaluation will examine fidelity, acceptability, sustainability and context. An economic evaluation will compare costs and consequences from the perspective of the local government, nursery and parents.

Whole-school interventions promoting student commitment to school to prevent substance use and violence: a systematic review

OBJECTIVES

Whole-school interventions that promote student commitment to school are a promising modality to reduce health inequalities through school-level change; however, evidence for the effectiveness of these interventions in improving policy-relevant health outcomes, such as substance use and violence, has not been comprehensively synthesised.

STUDY DESIGN

This was a systematic review and meta-analysis.

METHODS

We searched 20 databases and a range of other sources to identify randomised trials meeting our intervention definition and reporting substance use and violence outcomes. Extracted effect estimates were meta-analysed using robust variance estimation with random effects, separating effects <1 year from baseline and effects at or more than 1 year from baseline.

RESULTS

We included 18 evaluations with varying risk of bias. Pooled effects suggested significant impacts on short-term (odds ratio [OR] = 0.85, 95% confidence interval [CI] 0.76, 0.96) and long-term (OR = 0.79, 95% CI 0.65, 0.98) violence perpetration, short-term (OR = 0.84, 95% CI 0.72, 0.98) and long-term (OR = 0.85, 95% CI 0.73, 0.99) violence victimisation, and short-term (OR = 0.83, 95% CI 0.70, 0.97) and long-term (OR = 0.79, 95% CI 0.62, 0.998) substance use outcomes, with effects relatively stable between short-term and long-term analyses. Stratifying substance use meta-analyses by type (e.g. smoking, alcohol) did not impact results. All meta-analyses had substantial heterogeneity.

CONCLUSION

Although diverse in content, interventions appear effective with respect to the review outcomes and as a form of universal prevention. Future research should consider contextual contingencies in intervention effectiveness, given considerable policy and practice interest in these interventions and the need to support schools in effective decision-making as to intervention choice.

The Impact of Restorative Practices on the Use of Out-of-School Suspensions: Results from a Cluster Randomized Controlled Trial

The overuse of exclusionary discipline practices, such as out-of-school suspensions (OSS), has consistently been documented over several decades. The resulting racial discipline disparities and the negative outcomes related to OSS have led policy makers and educators to consider other approaches to school discipline. One such approach, which has gained increasing use in the USA, is restorative practices (RP). However, despite its popularity, the experimental evidence base of the effects of RP and suspensions is extremely limited. To add to this knowledge base, we present findings from a cluster randomized controlled trial with 18 K-12 schools in an urban district in the US Northeast with 5878 students. Multilevel regression results, after 1 year of the intervention, showed no differences in the likelihood of suspension between students in the intervention and control schools and that the effects of the intervention did not vary by race/ethnicity, gender, or student disability status. However, for students in the intervention group, we show reductions in the likelihood of receiving an OSS for students who had previously been suspended.

What happens when a whole-school health promotion research trial ends? a case study of the SEHER program in India

Background

Health promotion interventions that are developed and evaluated by researchers and other external providers are at risk of not being sustained beyond the initial implementation period. When delivered by a lay school health worker, the SEHER study of a whole-school health promotion intervention in Bihar, India was found to be feasible, acceptable and effective in improving school climate and student health behaviors. The objective of this case study is to describe the decision-making processes, barriers, and enablers to continuing the SEHER intervention following its official closure.

Methods

For this exploratory qualitative case study, data were collected from four government-run secondary schools, two of which continued SEHER and two of which discontinued it after official closure. Thirteen school staff were interviewed, and 100 girls and boys (aged 15-18  years old) participated in eight focus groups discussing their experiences of the process of continuing the intervention (or discontinuing) following its official closure. Thematic analysis was conducted in NVivo 12 using grounded theory.

Results

No school sustained the intervention as originally delivered in the research trial. In two schools, the intervention was adapted by selecting sustainable components, whereas in two others it was discontinued altogether. We identified four interrelated themes that explained the complex decision-making process, barriers, and enablers related to program continuation: (1) understanding of the intervention philosophy among school staff; (2) school capabilities to continue with intervention activities; (3) school attitudes and motivation about implementing the intervention, and; (4) the education policy environment and governance structures. Suggestions for overcoming barriers included adequate resource allocation; training, supervision, and support from external providers and the Ministry of Education; and formal government approval to continue the intervention.

Conclusion

Sustaining this whole-school health promotion intervention in low-resource school settings in India depended on individual, school and government factors as well as external support. These findings suggest that health interventions will not necessarily become embedded in a school's operations merely because they are designed as a whole-school approach or because they are effective. Research should identify the resources and processes required to balance planning for future sustainability while awaiting trial results about an intervention's effectiveness.

A qualitative exploration of stakeholder perspectives on the implementation of a whole school approach to mental health and emotional well-being in Wales

Early intervention to support mental health and well-being of school-aged children may be of significant benefit in preventing escalation of mental health problems in later life. While there are limitations to current understanding of the best ways for schools to support mental well-being, a whole school approach (WSA), involving all those who are part of the school system in creating and sustaining a supportive environment where health is prioritized, may be effective. This research explored stakeholder views of this approach, as part of a contract commissioned by the Welsh Government to conduct an evaluability assessment of a WSA. Semistructured focus groups and interviews were completed with stakeholders from the health and education sectors, as well as parents, to explore how a WSA may operate in a Welsh context and barriers and facilitators to potential implementation and outcomes. Findings suggest that existing pressures on schools may impact implementation of a WSA, with school staff already time poor and many staff experiencing their own mental well-being challenges. Implementation may be supported by clear guidance at local and national levels, funding for staff time and training and stakeholder involvement at all stages. Long-term monitoring and evaluation are also needed to understand system changes.

[Public mental health from an international perspective: from "shifting the curve" to inclusion of vulnerable populations]

In recent years, efforts in the field of public mental health have increased that seek to promote mental health and mental health literacy at population level and yield advances in the prevention, treatment and care of mental health conditions. This paper provides an overview of contemporary conceptualisations of indicators and determinants of public mental health as well as population-based intervention strategies from an international perspective. Current conceptual and methodological challenges of so-called high-risk, whole-population and vulnerable population strategies are critically discussed. Future efforts in research, policy and practice need to address fundamental causes of social and health inequalities, drawing on all societal fields, to contribute to improving population mental health.

Cost-utility analysis of the UPRIGHT intervention promoting resilience in adolescents

BACKGROUND

As mental health in adulthood is related to mental status during adolescence, school-based interventions have been proposed to improve resilience. The objective of this study was to build a simulation model representing the natural history of mental disorders in childhood, adolescence and youth to estimate the cost-effectiveness of the UPRIGHT school-based intervention in promoting resilience and mental health in adolescence.

METHODS

We built a discrete event simulation model fed with real-world data (cumulative incidence disaggregated into eight clusters) from the Basque Health Service database (609,381 individuals) to calculate utilities (quality-adjusted life years [QALYs]) and costs for the general population in two scenarios (base case and intervention). The model translated changes in the wellbeing of adolescents into different risks of mental illnesses for a time horizon of 30 years.

RESULTS

The number of cases of anxiety was estimated to fall by 5,125 or 9,592 and those of depression by 1,269 and 2,165 if the effect of the intervention lasted 2 or 5 years respectively. From a healthcare system perspective, the intervention was cost-effective for all cases considered with incremental cost-utility ratios always lower than €10,000/QALY and dominant for some subgroups. The intervention was always dominant when including indirect and non-medical costs (societal perspective).

CONCLUSIONS

Although the primary analysis of the trial did not did not detect significant differences, the UPRIGHT intervention promoting positive mental health was dominant in the economic evaluation from the societal perspective. Promoting resilience was more cost-effective in the most deprived group. Despite a lack of information about the spillover effect in some sectors, the economic evaluation framework developed principally for pharmacoeconomics can be applied to interventions to promote resilience in adolescents. As prevention of mental health disorders is even more necessary in the post-coronavirus disease-19 era, such evaluation is essential to assess whether investment in mental health promotion would be good value for money by avoiding costs for healthcare providers and other stakeholders.

School-Based Nursing Interventions for Preventing Bullying and Reducing Its Incidence on Students: A Scoping Review

Incidents of bullying have increased on students in schools. This has a negative impact such as mental health problems and risk of suicide. Interventions related to bullying are still focused on being carried out independently. Meanwhile, collaborative interventions between nurses and the school are needed to acquire maximum results in preventing and reducing the incidence of bullying. The purpose of this study is to describe school-based nursing interventions in preventing and reducing the incidence of bullying among students at school. This study used scoping review with a search strategy using the PRISMA Extension for Scoping Review process to find the articles. The PubMed, CINAHL, and Scopus electronic databases were searched. We found 12 articles from 594 articles in 3 databases which discussed nursing interventions based on school to prevent and reduce incidence of bullying in students. The studies included are design randomized control trials and quasi experiments. The samples with the range of 40-7121 respondents. We classified the school-based nursing interventions being three methods, there are Game programs, physical activity programs, training programs, and peer-group programs. The content of interventions are psychoeducation, empathy training, counseling, and self-management. This study shows that school-based nursing interventions can be an option in preventing and reducing the incidence of bullying among students at school.

School-based mental health promotion: A global policy review

Objectives

Schools are increasingly recognized as important settings for mental health promotion, but it is unclear what actions schools should prioritize to promote student mental health and wellbeing. We undertook a policy review of global school-based mental health promotion policy documents from United Nations (UN) agencies to understand the frameworks they use and the actions they recommend for schools.

Methods

We searched for guidelines and manuals from UN agencies through the World Health Organization (WHO) library, the National Library of Australia and Google Scholar, from 2000 to 2021, using various combinations of search terms (e.g., mental health, wellbeing, psychosocial, health, school, framework, manual, and guidelines). Textual data synthesis was undertaken.

Results

Sixteen documents met inclusion criteria. UN policy documents commonly recommended a comprehensive school-health framework aimed at integrating actions to prevent, promote, and support mental health problems within the school community. The primary role of schools was framed around building enabling contexts for mental health and wellbeing. Terminology was relatively inconsistent across different guidelines and manuals, particularly around how comprehensive school health was conceptualized, which included aspects of scope, focus, and approach.

Conclusion

United Nations policy documents are oriented toward comprehensive school-health frameworks for student mental health and wellbeing that include mental health within wider health-promoting approaches. There are expectations that schools have the capabilities to deliver actions to prevent, promote and support mental health problems.

Implication

Effective implementation of school-based mental health promotion requires investments that facilitate specific actions from governments, schools, families, and communities.

Evaluation of the whole school restorative practices project: One-year impact on discipline incidents

The current study addressed the need for experimental research on Restorative Practices (RP) in its evaluation of the Morningside Center for Teaching Social Responsibility's Whole School RP Project. The study was conducted in a large Northeastern city using a cluster randomized controlled design in 18 elementary, middle, and high schools. In a single year, before the COVID-19 pandemic, and with data from 5878 students, the study found that overall, students in the RP Project schools were less likely to receive a discipline incident record (11.1%) as compared to students in the comparison schools (18.2%). However, differential treatment effects based on sex, race/ethnicity, and disability status were not found. The findings suggest prevention efforts are a cornerstone of practice/policy reforms to reduce the use of exclusionary discipline. Findings also suggest multi-year initiatives are needed to address discipline disparities.

School-based interventions for preventing dating and relationship violence and gender-based violence: A systematic review and synthesis of theories of change

School-based interventions for preventing dating and relationship violence (DRV) and gender-based violence (GBV) are an important way of attempting to prevent and reduce the significant amount of DRV and GBV that occurs in schools. A theoretical understanding of how these interventions are likely to cause change is essential for developing and evaluating effectiveness, so developing an overarching theory of change for school-based interventions to prevent DRV and GBV was the first step in our systematic review. Theoretical data were synthesised from 68 outcome evaluations using methods common to qualitative synthesis. Specifically, we used a meta-ethnographic approach to develop a line-of-argument for an overarching theory of change and Markham and Aveyard's (2003, Social Science & Medicine, 56, 1209) theory of human functioning and school organisation as a framework for structuring the concepts. The overall theory of change generated was that by strengthening relationships between and among staff and students, between the classroom and the wider school, and between schools and communities, and by increasing students' sense of belonging with student-centred learning opportunities, schools would encourage student commitment to the school and its values, prosocial behaviour and avoidance of violence and aggression. The theory of human functioning informed our understanding of the mechanisms of action but from our analysis we found that it required refinement to address the importance of context and student agency.

Research Review: Do antibullying interventions reduce internalizing symptoms? A systematic review, meta-analysis, and meta-regression exploring intervention components, moderators, and mechanisms

BACKGROUND

Effective antibullying interventions may reduce the impact of bullying on young people's mental health. Nevertheless, little is known about their effectiveness in reducing internalizing symptoms such as anxiety or depression, and what factors may influence intervention effects. The aim of this systematic review, meta-analysis, and metaregression is to assess the effects of school-based antibullying interventions on children's and adolescent's internalizing symptoms. The secondary aims are to explore potential moderators, intervention components, and reductions in bullying as mediators of intervention effects on internalizing symptoms.

METHODS

We searched nine databases: PsycINFO, Web of Science, ERIC, SCOPUS, CINAHL, Medline, Embase, ProQuest, and Cochrane Library, and performed an author search of included studies in English from January 1983 to April 2021. We included studies that evaluated school-based antibullying interventions using controlled designs and reporting on both bullying and internalizing outcomes. Random-effects and metaregression models were used to derive Hedges g values with pooled 95% CIs as estimates of effect size and to test associations between moderator variables and effect size estimates. Path analysis was used to test potential mediation using effect size measures of victimization, perpetration, and internalizing outcomes. Quality and risk of bias were assessed using Cochrane collaboration tools.

RESULTS

This review included 22 studies with 58,091 participants in the meta-analysis. Antibullying interventions had a very small effect in reducing overall internalizing symptoms (ES, 0.06; 95% CI, 0.0284 to 0.1005), anxiety (ES, 0.08; 95% CI, 0.011 to 0.158), and depression (ES, 0.06; 95% CI, 0.014 to 0.107) at postintervention. The reduction in internalizing symptoms did not vary significantly across geographic location, grade level, program duration, and intensity. The intervention component 'working with peers' was associated with a significant reduction, and 'using CBT techniques' was associated with a significant increase in internalizing outcomes. Bullying victimization and perpetration did not mediate the relationship between intervention condition and internalizing outcomes.

CONCLUSIONS

Antibullying interventions have a small impact on reducing internalizing symptoms. Ongoing development of antibullying interventions should address how best to maximize their impact on internalizing symptoms to safeguard young people from the damaging mental health outcomes of bullying.

The role of school connectedness in the prevention of youth depression and anxiety: a systematic review with youth consultation

Background

School connectedness reflects the quality of students’ engagement with peers, teachers, and learning in the school environment. It has attracted attention from both the health and education sectors as a potentially modifiable protective factor for common mental health problems. However, the extent to which school connectedness may prevent the onset of youth depression or anxiety or promote their remission is unclear. This systematic review examined evidence for prospective relationships between school connectedness and depression and anxiety, and the effect of interventions to improve school connectedness on depression and anxiety.

Methods

We searched MEDLINE, PsycINFO, PubMed, and ERIC electronic databases for peer-reviewed quantitative longitudinal, or intervention studies published from 2011–21 in English examining relationships between school connectedness and anxiety and/or depression. Participants were 14–24 years old when depression and anxiety outcomes were assessed in any education setting in any country. We partnered with five youth advisers (aged 16–21 years) with lived experience of mental health problems and/or the schooling system in Australia, Indonesia, and the Philippines to ensure that youth perspectives informed the review.

Results

Our search identified 3552 unique records from which 34 longitudinal and 2 intervention studies were ultimately included. Studies were primarily from the United States of America (69.4%). Depression and anxiety outcomes were first measured at 14 years old, on average. Most studies found a significant protective relationship between higher levels of school connectedness and depressive and/or anxiety symptoms; more measured depression than anxiety. A few studies found a non-significant relationship. Both intervention studies designed to increase school connectedness improved depression, one through improvements in self-esteem and one through improvements in relationships at school.

Conclusions

These findings suggest that school connectedness may be a novel target for the prevention of depression and anxiety. We were not able to determine whether improving school connectedness promotes remission in young people already experiencing depression and anxiety. More studies examining anxiety, diagnostic outcomes, and beyond North America are warranted, as well as intervention trials.

Method of Nursing Interventions to Reduce the Incidence of Bullying and Its Impact on Students in School: A Scoping Review

The bullying of students in schools can have a negative impact on students. The impact of bullying can take the form of anxiety, low psychological well-being, low social adjustment, psychological distress, and risk of suicide. Incidents of bullying are still considered normal, and there has not been a focus on reducing their incidence and impact. The purpose of this study is to describe nursing interventions to reduce the incidence of bullying and its impact on students at school. This study used the scoping review method and literature reviews via CINAHL, PubMed, and ProQuest databases. The keywords used in English were "bullying OR cyberbullying OR aggression" AND "students OR school students" AND "school OR schools" AND "nursing intervention". The criteria for articles in this study were: full texts, student populations and samples, randomized control trials or quasi-experiment research designs, use of the English language, and the publication period of the last 10 years (2013-2022). We found 11 articles discussing nursing interventions to reduce the incidence of bullying and its impact on students in schools. There are four types of interventions that can be provided to students, namely, prevention programs, activities programs, peer group programs, and resilience programs. Most of the articles used randomized control trials and quasi-experiment designs. The samples in the articles analyzed were in the range of 50-7121 students. These four types of interventions can reduce the incidence of bullying and its impact on students at school, and in addition, they can improve the social skills and mental health of students, for example, by increasing their self-efficacy, resilience, and adaptive coping. There are four nursing interventions to reduce the incidence of bullying and its impact on students in schools, namely, the prevention program, activities program, peer group program, and resilience program.

How are parenting practices associated with bullying in adolescents? A cross-sectional study

BACKGROUND

Parenting styles have been previously associated with bullying, but some parenting practices have not received strong attention in the literature. We aimed to assess how parenting practices are associated with cyberbullying and traditional bullying involvement in adolescents.

METHOD

A cross-sectional survey of 2,218 secondary-school students in London (UK) was conducted. The Olweus Bully/Victim Questionnaire and the Alabama Parenting Questionnaire (APQ-child form) were used.

RESULTS

Positive parenting significantly protected against cyberbullying involvement but not against traditional bullying. Inconsistent discipline was associated with being a cyberbully but not being a traditional one. Lower levels of monitoring were associated with being a cyberbully, a cyberbully-victim, a traditional bully, or a traditional bully-victim.

CONCLUSIONS

Parenting practices seem to be more relevant in cyberbullying than traditional bullying. Effective parenting practices such as positive parenting deserve attention as a potentially modifiable factor to protect against cyberbullying involvement. Ineffective parenting practices such as inconsistent discipline are relevant in cyberaggression, whereas poor monitoring is associated with both cyberbullying and traditional bullying. Clinical and research implications are discussed.

Depression in young people

Depression rates in young people have risen sharply in the past decade, especially in females, which is of concern because adolescence is a period of rapid social, emotional, and cognitive development and key life transitions. Adverse outcomes associated with depression in young people include depression recurrence; the onset of other psychiatric disorders; and wider, protracted impairments in interpersonal, social, educational, and occupational functioning. Thus, prevention and early intervention for depression in young people are priorities. Preventive and early intervention strategies typically target predisposing factors, antecedents, and symptoms of depression. Young people who have a family history of depression, exposure to social stressors (eg, bullying, discordant relationships, or stressful life events), and belong to certain subgroups (eg, having a chronic physical health problem or being a sexual minority) are at especially high risk of depression. Clinical antecedents include depressive symptoms, anxiety, and irritability. Evidence favours indicated prevention and targeted prevention to universal prevention. Emerging school-based and community-based social interventions show some promise. Depression is highly heterogeneous; therefore, a stepwise treatment approach is recommended, starting with brief psychosocial interventions, then a specific psychological therapy, and then an antidepressant medication.

Components Related to Long-Term Effects in the Intra- and Interpersonal Domains: A Meta-Analysis of Universal School-Based Interventions

The aims of the present meta-analysis were to (1) examine long-term effects of universal secondary school-based interventions on a broad range of competencies and problems and (2) analyze which intervention components were related to stronger or weaker intervention effects at follow-up. Fifty-four studies of controlled evaluations (283 effect sizes) reporting on 52 unique interventions were included. Long-term intervention effects were significant but small; effect sizes ranged from .08 to .23 in the intrapersonal domain (i.e., subjective psychological functioning) and from .10 to .19 in the interpersonal domain (i.e., social functioning). Intervention components were generally related to effects on specific outcomes. Some components (e.g., group discussions) were even related to both stronger and weaker effects depending on the assessed outcome. Moreover, components associated with long-term effects differed from those associated with short-term effects. Our findings underscore the importance of carefully selecting components to foster long-term development on specific outcomes.

Safety Risks of Primary and Secondary Schools in China: A Systematic Analysis Using AHP–EWM Method

Owing to the frequent accidents in primary and secondary schools (PSS) in China in the past decades, a systematic analysis of indicators influencing safety risks in PSS is critical to identifying preventive measures. A two-hierarchy structure of indicators was identified by analyzing various cases, intensive interviews, and related previous literature. A combination of the analytic hierarchy process and the entropy weight method was developed to synthetically assess the primary and secondary risk indicators through a case study of Ma Shan School in China. The results are as follows: (1) the primary risk indicators, namely, natural disasters, public health, facility safety, accidental injury, public security, school bullying, and individual health constitute the evaluation framework of the safety risks in PSS. (2) Public health risks and accidental injury risks are the most critical factors that should be prioritized. In addition to providing academic implications, several managerial implications are proposed for these stakeholders to reduce the safety risks in PSS.

Relationship between school bullying and mental health status of adolescent students in China: A nationwide cross-sectional study

INTRODUCTION

School bullying, as a public health problem, has been linked to many emotional disorders. However, the overall status of school bullying among adolescent students in China is unknown. This nationwide study aimed to investigate school bullying in China and evaluate the relationships between school bullying and mental health status.

METHODS

A total of 15, 415 middle and high school students were enrolled in this study through multistage stratified cluster random sampling. Multinomial logistic regression models were used to examine the association between school bullying and mental health status and the analysis was stratified by gender.

RESULTS

Students were divided into four groups: 2.72%, bully/victims; 1.38%, bullies; 10.89%, victims; 85.01%, uninvolved. Compared with uninvolved students, students with anxiety symptoms, non-suicidal self-injury and suicide ideation had a higher risk of being involved in school bullying and were more likely to be bully/victims, bullies, and victims. Stratified analysis indicated that boys with anxiety symptoms and non-suicidal self-injury risks tended to be bullies, victims and bully/victims. However, for girls, bullying others or being bullied was related to anxiety symptoms and suicide ideation.

CONCLUSION

Our study indicated that school bullying is still a health problem in the adolescent students of China, and is related to many mental health problems. Intervention programs are in urgent need to help the students involved in school bullying, both in terms of their mental and physical health.
