Impact of health behaviours and deprivation on well-being in a national sample of English young people

The relationship between adolescent sleep duration and exposure to school bullying: the masking effect of depressive symptoms

Background

Adolescents who suffer from school bullying are often accompanied by problems such as sleep disorders and depression. However, it remains unclear how depressive symptoms and sleep assessments such as sleep duration interact in the specific mechanisms of exposure to school bullying.

Objective

To understand the role of sleep duration, depressive symptoms on school bullying in adolescents and the mediating role of sleep duration in this context.

Methods

A total of 1730 adolescents were selected from Xinjiang province, China by stratified cluster random sampling in 2020, and their demographic characteristics, exposure to school bullying, depressive symptoms, and sleep duration were investigated by questionnaire. Multifactorial logistics regression analyses were performed to examine the effects of sleep duration and depressive symptoms on school bullying. Furthermore, the bootstrap method was used to explore the mediating effect and masking effect of depressive symptoms between sleep duration and school bullying by PROCESS macro in SPSS 26.0.

Results

A total of 16.42% of adolescents suffered from school bullying and 12.25% showed depressive symptoms. Multifactorial logistics regression analyses revealed that possible depression and depression increase the risk of exposure to school bullying compared to normal group. Sleep duration less than 8 h and between 8 and 10 h are protective factors for exposure to three types of school bullying relative to those who sleep more than 10 h. Additionally, sleep duration affected exposure to school bullying through depressive symptoms (β = 0.011) and depressive symptoms masked the effect between sleep duration and exposure to school bullying with an effect of 60.17%. The masking effect remained stable after adjusting for gender, age, ethnicity, body mass index, and exercise intensity (indirect effect = -0.017, 95%CI: -0.026 to -0.009).

Conclusion

Depressive symptoms may be a risk factor for exposure to school bullying, while moderate and inadequate sleep duration may be protective factors for exposure to all three types of school bullying simultaneously. The effect of sleep duration on adolescents' exposure to school bullying was affected by the masking effect of depressive symptoms, and appropriate sleep duration and a positive and healthy mindset were beneficial in reducing the occurrence of school bullying.

Latent classes of adolescent health behaviour, social covariates and mental wellbeing: a longitudinal birth cohort study

BACKGROUND

Adolescent mental wellbeing has been declining in the United Kingdom for over a decade. Expansion of services to support the mental wellbeing of young people is a public health priority and a core component of the National Health Service's Long-Term Plan. In this paper, we leverage secondary analysis of a very large longitudinal dataset (#BeeWell) to generate insights regarding different patterns of health behaviour, their covariates, and consequences for mental wellbeing one year later.

METHODS

A Latent Class Analysis was conducted using data on physical activity, sleep, and eating habits collected in 2021 from 18,478 Year 8 pupils from Greater Manchester (United Kingdom) to (1) identify distinct latent classes of adolescent health behaviour; (2) establish factors likely to be associated with latent class membership; and (3) determine whether latent class membership contributes to variance in self-reported mental wellbeing one year later.

RESULTS

A three-class solution was identified as an excellent fit to the data, discriminating between: the Wellness Weary (n = 2,717; 15%); the Balanced Bunch (n = 7,377; 40%); and the Green and Dream Team (n = 8,384; 45%). Several factors significantly influenced class membership. Most notably, socio-economic disadvantage and social media use were linked with less favourable health behaviour patterns, whilst cisgender heterosexual girls were likely to endorse healthier patterns. After adjusting for covariates, the Green and Dream Team reported significantly greater mental wellbeing than the Balanced Bunch one year later. However, there was no difference between the Balanced Bunch and the Wellness Weary, signalling that health behaviours may support mental wellbeing, but only among the healthiest young people.

CONCLUSIONS

Beyond advancements in fundamental understanding, our findings yield significant translation opportunities through their use and application in health, education, and allied professional settings designed to support young people.

Adolescents' interactive electronic device use, sleep and mental health: a systematic review of prospective studies

Optimal sleep, both in terms of duration and quality, is important for adolescent health. However, young people's sleeping habits have worsened over recent years. Access to and use of interactive electronic devices (e.g., smartphones, tablets, portable gaming devices) and social media have become deep-rooted elements of adolescents' lives and are associated with poor sleep. Additionally, there is evidence of increases in poor mental health and well-being disorders in adolescents; further linked to poor sleep. This review aimed to summarise the longitudinal and experimental evidence of the impact of device use on adolescents' sleep and subsequent mental health. Nine electronic bibliographical databases were searched for this narrative systematic review in October 2022. Of 5779 identified unique records, 28 studies were selected for inclusion. A total of 26 studies examined the direct link between device use and sleep outcomes, and four reported the indirect link between device use and mental health, with sleep as a mediator. The methodological quality of the studies was generally poor. Results demonstrated that adverse implications of device use (i.e., overuse, problematic use, telepressure, and cyber-victimisation) impacted sleep quality and duration; however, relationships with other types of device use were unclear. A small but consistent body of evidence showed sleep mediates the relationship between device use and mental health and well-being in adolescents. Increasing our understanding of the complexities of device use, sleep, and mental health in adolescents are important contributions to the development of future interventions and guidelines to prevent or increase resilience to cyber-bullying and ensure adequate sleep.

The associations between screen time and mental health in adolescents: a systematic review

BACKGROUND

Adolescents have extensive use of screens and, they have common complains related to mental health. Here a systematic review was done to understand the association between screen time and adolescent's mental health.

METHOD

This review was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA. An update search was performed in January 2023 with the following keywords: "screen time," "adolescent," and "mental health" on PubMed, PsycINFO and Scopus databases.

RESULTS

50 articles were included, most have found associations between screen exposure and mental health in adolescents. The most used device by adolescents was the smartphone and the use on weekdays was associated with diminished mental well-being. Social media use was negatively associated with mental well-being and, in girls, associated at higher risk for depression.

CONCLUSION

Excessive screen time in adolescents seems associated with mental health problems. Given the profusion and disparity of the results, additional studies are needed to clarify elements such as the screen content or the interaction of adolescents with different screen devices.

Dose-response associations between modifiable lifestyle behaviours and anxiety, depression and psychological distress symptoms in early adolescence

OBJECTIVE

To investigate associations between key modifiable lifestyle behaviours (sleep; physical activity; fruit, vegetable and sugar-sweetened beverage consumption; screen time; alcohol use and tobacco use) and mental health among early adolescents in Australia.

METHODS

Cross-sectional self-report data from 6,640 Year 7 students (M_age:12.7[0.5]; 50.6% male, 48.9% female, 0.5% non-binary) from 71 schools in New South Wales, Queensland and Western Australia were analysed using multivariate linear regression adjusting for sociodemographic factors and school-level clustering.

RESULTS

All examined behaviours were associated with anxiety, depression and psychological distress (p≤0.001), with the lowest mental health symptom scores observed in participants who slept 9.5-10.5 hours per night; consumed three serves of fruit daily; consumed two serves of vegetables daily; never or rarely drank sugar-sweetened beverages; engaged in six days of moderate-to-vigorous physical activity per week; kept daily recreational screen time to 31-60 minutes; had not consumed a full standard alcoholic drink (past six months); or smoked a cigarette (past six months).

CONCLUSIONS

Targeting modifiable risk behaviours offers promising prevention potential to improve adolescent mental health; however, further longitudinal research to determine directionality and behavioural interactions is needed.

IMPLICATIONS FOR PUBLIC HEALTH

While Australian Dietary, Movement and Alcohol Guidelines target physical health, findings indicate similar behaviour thresholds may offer mental health benefits.

The association between resilience resources, contextual factors and mental health status: a national population-based study

Background

Although a range of risk factors have been linked with poor mental health across the population, the underlying pathways leading to mental ill health remain unclear. There is a need to investigate the effects and interplay of both protective and risk factors. This population-based study aimed to explore the effects of individual and contextual factors on mental health status. Record-linkage was implemented between health and lifestyle data drawn from HealthWise Wales (HWW), a national population health survey of people > 16 years who live or access their healthcare in Wales, and treatment data from primary healthcare records. Mental health status was assessed using three different measures, including the self-reported MHI-5 and WEMWBS scales and mental health treatment in electronic healthcare records (EHR).

Result

Using cross-sectional data from 27,869 HWW participants aged over 16 years, lifestyle factors, resilience, social cohesion and neighbourhood attraction were associated with mental health across all measures. However, compared to contextual factors, the cluster of individual factors was more closely associated with poor mental health, explaining more of the variance across all measures used (MHI-5: 9.8% versus 5.4%; WEMWBS: 15.9% versus 10.3%; EHR: 5.5% versus 3.0%). Additional analysis on resilience sub-constructs indicated that personal skills were the most closely correlated with poorer mental health.

Conclusion

Mental health status was more closely linked with individual factors across the population than contextual factors. Interventions focusing on improving individual resilience and coping skills could improve mental health outcomes and reduce the negative effect of contextual factors such as negative neighbourhood perceptions.

Cross-sectional associations of schoolchildren's fruit and vegetable consumption, and meal choices, with their mental well-being: a cross-sectional study

BACKGROUND

Poor mental well-being is a major issue for young people and is likely to have long-term negative consequences. The contribution of nutrition is underexplored. We, therefore, investigated the association between dietary choices and mental well-being among schoolchildren.

METHODS

Data from 7570 secondary school and 1253 primary school children in the Norfolk Children and Young People Health and Well-being Survey, open to all Norfolk schools during October 2017, were analysed. Multivariable linear regression was used to measure the association between nutritional factors and mental well-being assessed by the Warwick-Edinburgh Mental Well-being Scale for secondary school pupils, or the Stirling Children's Well-being Scale for primary school pupils. We adjusted all analyses for important covariates including demographic, health variables, living/home situation and adverse experience variables.

RESULTS

In secondary school analyses, a strong association between nutritional variables and well-being scores was apparent. Higher combined fruit and vegetable consumption was significantly associated with higher well-being: well-being scores were 3.73 (95% CI 2.94 to 4.53) units higher in those consuming five or more fruits and vegetables (p<0.001; n=1905) compared with none (n=739). The type of breakfast or lunch consumed was also associated with significant differences in well-being score. Compared with children consuming a conventional type of breakfast (n=5288), those not eating any breakfast had mean well-being scores 2.73 (95% CI 2.11 to 3.35) units lower (p<0.001; n=1129) and those consuming only an energy drink had well-being scores 3.14 (95% CI 1.20 to 5.09) units lower (p=0.002; n=91). Likewise, children not eating any lunch had well-being scores 2.95 (95% CI 2.22 to 3.68) units lower (p<0.001; 860) than those consuming a packed lunch (n=3744). In primary school analyses, the type of breakfast or lunch was associated with significant differences in well-being scores in a similar way to those seen in secondary school data, although no significant association with fruit and vegetable intake was evident.

CONCLUSION

These findings suggest that public health strategies to optimise the mental well-being of children should include promotion of good nutrition.

Associations between psychological wellbeing, depression, general anxiety, perceived social support, tooth brushing frequency and oral ulcers among adults resident in Nigeria during the first wave of the COVID-19 pandemic

INTRODUCTION

The aims of this study were to determine the associations between psychological wellbeing, and the frequency of tooth brushing and presence of oral ulcers during the COVID-19 pandemic; and to identify the mediating roles of psychological distress (general anxiety and depression) and perceived social support in the paths of observed associations.

METHODS

This cross-sectional study recruited 996 adults in Nigeria between June and August 2020. Data collected through an online survey included outcome variables (decreased frequency of tooth brushing and presence of oral ulcers), explanatory variable (psychological wellbeing), mediators (general anxiety symptoms, depression symptoms and perceived social support) and confounders (age, sex at birth, educational and employment status). Multivariate logistic regression was used to determine the risk indicators for the outcome variables. A path analysis was conducted to identify the indirect effect of mediators on the association between the outcome and explanatory variables.

RESULTS

Of the 966 respondents, 96 (9.9%) reported decreased tooth-brushing frequency and 129 (13.4%) had oral ulcers during the pandemic. The odds of decreased tooth-brushing during the pandemic decreased as the psychological wellbeing increased (AOR: 0.87; 95% CI: 0.83-0.91; p < 0.001) and as generalized anxiety symptoms increased (AOR: 0.92; 95% CI: 0.86-0.98; p = 0.009). The odds of having an oral ulcer was higher as the generalized anxiety symptoms increased (AOR: 1.15; 95% CI: 01.08-1.21; p < 0.001). Only generalized anxiety (indirect effect: 0.02; 95% CI: 0.01-0.04; P = 0.014) significantly mediated the relationship between wellbeing and tooth-brushing accounting for approximately 12% of the total effect of wellbeing on decreased toothbrushing. Generalized anxiety (indirect effect 0.05; 95% CI: - 0.07-0.03; P < 0.001) also significantly mediated the relationship between wellbeing and presence of oral ulcer accounting for 70% of the total effect of wellbeing on presence of oral ulcer. Depressive symptoms and perceived social support did not significantly mediate the associations between psychological wellbeing, decreased frequency of tooth brushing and the presence of oral ulcers.

CONCLUSION

Patients who come into the dental clinic with poor oral hygiene or oral ulcers during the COVID-19 pandemic may benefit from screening for generalized anxiety and psychological wellbeing to identify those who will benefit from interventions for mental health challenges.

Association between Physical Activity and Sleep Difficulties among Adolescents in Germany: The Role of Socioeconomic Status

We examined sleep difficulties among adolescents in Germany and the association with physical activity (PA). Furthermore, we analyzed whether the association varied with the socioeconomic status (SES) among adolescent girls and boys in Germany. Using data from the German Health Interview Examination Survey for Children and Adolescents (KiGGS) study (Wave 2), 6599 adolescents aged 11 to 17 years were included in the analyses. We conducted sex-stratified logistic regression analyses. Dependent variables were unrecommended sleep duration (defined as a duration of sleep that does not meet the recommended duration), sleep-onset difficulties, trouble sleeping, and daytime sleepiness. Most adolescent girls and boys reported sleep difficulties. While no associations between PA and sleep difficulties were observed, a significant interaction between PA and SES was found for sleep duration in boys and daytime sleepiness in girls. Thus, adolescents with low SES had fewer sleep difficulties if they met the recommendation for PA, compared with those in other SES groups. In Germany, a large proportion of adolescents have sleep difficulties. We found that the experience of sleep difficulties varied according to PA, sex, and the family SES. Future sleep promotion programs should consider these differences.

Heterogeneity of Research Results: A New Perspective From Which to Assess and Promote Progress in Psychological Science

Heterogeneity emerges when multiple close or conceptual replications on the same subject produce results that vary more than expected from the sampling error. Here we argue that unexplained heterogeneity reflects a lack of coherence between the concepts applied and data observed and therefore a lack of understanding of the subject matter. Typical levels of heterogeneity thus offer a useful but neglected perspective on the levels of understanding achieved in psychological science. Focusing on continuous outcome variables, we surveyed heterogeneity in 150 meta-analyses from cognitive, organizational, and social psychology and 57 multiple close replications. Heterogeneity proved to be very high in meta-analyses, with powerful moderators being conspicuously absent. Population effects in the average meta-analysis vary from small to very large for reasons that are typically not understood. In contrast, heterogeneity was moderate in close replications. A newly identified relationship between heterogeneity and effect size allowed us to make predictions about expected heterogeneity levels. We discuss important implications for the formulation and evaluation of theories in psychology. On the basis of insights from the history and philosophy of science, we argue that the reduction of heterogeneity is important for progress in psychology and its practical applications, and we suggest changes to our collective research practice toward this end.

A pre-evaluation of psychological factors may positively affect the outcomes of smoking cessation treatments: A comparison in terms of smoking behavior

INTRODUCTION

The aim of this study was to compare smoking behavior in out-patients in terms of psychological factors with a view to supporting cessation treatment.

METHODS

We conducted a cross-sectional and analytical study through face-to-face interviews by the primary care physician with 765 volunteer participants who applied to our hospital for any reason between March and July 2019. The questionnaire administered had two parts: questions about sociodemographic characteristics and usage of tobacco and tobacco products, and questions of the UCLA Loneliness Scale, Multidimensional Scale of Perceived Social Support (MSPSS), Warwick-Edinburgh Mental Wellbeing Scale (WEMBS), and Fagerström Test for Nicotine Dependence (FTND).

RESULTS

The study was completed with 765 participants of which 53.1% (n=406) were female and 46.9% (n=359) male. Multidimensional perceived social support scale mean score of the participants was 69.9±15.2 (min=12, max=84). There was a significant relation between mean MPSS and mean WEMBS (p<0.05). As nicotine scores increased, the mean scores both in MPSS and WEMBS decreased (p<0.05).

CONCLUSIONS

We suggest that the results of the psychometric preliminary evaluations should be customized for individuals applying to smoking cessation clinics and that including the individual's close social connections in the process can facilitate the decision to quit, thus increase smoking cessation rates.

"Girls Aren't Meant to Exercise": Perceived Influences on Physical Activity among Adolescent Girls-The HERizon Project

Background. Adolescent girls are less active than boys, with approximately 10% of girls in Ireland and the United Kingdom meeting the minimum recommended daily physical activity (PA) guidelines. This study investigated factors perceived to influence PA among adolescent girls from low socioeconomic areas in order to inform the design of a future intervention (The HERizon Project). Methods. A total of 48 adolescent girls (13–18 years) from low socioeconomic areas of the United Kingdom and Ireland participated in focus groups (n = 8), to explore perspectives of physical activity and the influence of gender within this. Focus groups were thematically analyzed and interpreted within a socioecological framework. Results. Most girls enjoyed PA and were aware of its benefits. They identified both barriers and facilitators to PA at intrapersonal (fear of judgement and changing priorities WITH age), interpersonal (changing social pressures and support from others) and organizational (delivery of PE) levels. Gender inequality was a multilevel factor, crossing all socioecological levels. Conclusion. Although many adolescent girls enjoy PA, their experiences appear to be limited by a fear of judgement and an overarching sense of gender inequality. Future interventions, such as the HERizon Project, should address influences at intrapersonal, interpersonal and organizational levels to promote positive PA experiences for adolescent girls.

Sleep Duration, Sleep Quality and Physical Activity, but Not Sedentary Behaviour, Are Associated with Positive Mental Health in a Multi-Ethnic Asian Population: A Cross-Sectional Evaluation

BACKGROUND

We assessed the associations of sleep, physical activity and sedentary behaviour with positive mental health (PMH) in the multi-ethnic population of Singapore.

METHODS

The Singapore Health 2 study is a nationally representative cross-sectional survey among residents aged 18-79 years. A PMH instrument was administered to 1925 participants to obtain total PMH and six sub-component scores. Self-rated sleep duration, sleep quality, sedentary behaviour and physical activity were assessed. Multivariable linear regression analyses were conducted.

RESULTS

The mean age of the participants was 40.1 (SD 14.3) years. Sleep duration (≥8 h/night: β = 0.17,95% CI: 0.02-0.32; 7-< 8 h/night: β = 0.17,95% CI: 0.03-0.30 versus <6 h/night, p = 0.002), sleep quality (very good: β = 0.45,95% CI: 0.29-0.60; fairly good: β = 0.20,95% CI: 0.06-0.33 versus very/fairly bad; ptrend < 0.001) and physical activity (high: β = 0.19,95% CI: 0.05-0.32; moderate: β = 0.15, 95% CI: 0.03-0.27 versus low; ptrend < 0.001) were directly associated with total PMH. Sedentary behaviour was not significantly associated with PMH. Sleep duration, sleep quality and physical activity were directly associated with the PMH sub-components 'emotional support' and 'personal growth and autonomy'.

CONCLUSIONS

Duration and quality of sleep and physical activity were directly associated with PMH in an urban Asian population. These findings support incorporating sleep and physical activity interventions to improve population mental health.

Implications of personality and parental education on healthy lifestyles among adolescents

Several studies have shown an association between personality and health status. The aim of this study was to evaluate the association between personality traits, parental education and health-related lifestyles in a cohort of Spanish adolescents. This is a longitudinal study with a source population of 1,123 third-year students (aged 14-15) in secondary schools in Spain. At the baseline evaluation sociodemographic variables, parental education and personality (Big Five Questionnaire for Children) were collected. At 18 months of follow-up health related lifestyles, including adherence to a healthy diet (KidMed index), tobacco and alcohol consumption, physical exercise, sleep problems and recreative screen and social network time were collected. A total of 824 adolescents (73.4%) completed the 18 months assessment and 695 (84.3%) presented valid data. Higher conscientiousness was associated to a lower risk for non-adherence to Mediterranean diet (OR = 0.7, 95% CIs=0.5-0.9), tobacco (OR = 0.5, 95% CIs=0.3-0.7) and alcohol consumption (OR = 0.6, 95% CIs=0.5-0.8), excessive use of screens (OR = 0.7, 95% CIs=0.5-0.9) and social network sites (OR = 0.7, 95% CIs=0.5-0.8). Higher levels of extraversion was significantly related to a lower risk of physical inactivity (OR = 0.7, 95% CIs=0.6-0.9), but they are at a higher risk of low adherence to Mediterranean diet (OR = 1.3, 95% CIs=1.0-1.7), tobacco (OR = 2.7, 95% CIs=1.7-4.3) and alcohol consumption (OR = 1.9, 95% CIs=1.5-2.4) and excessive use of social network sites (OR = 1.6, 95% CIs=1.3-1.9). High levels of emotional instability were associated with tobacco consumption (OR = 1.5, 95% CIs=1.0-2.2) and sleep problems (OR = 2.0, 95% CIs=1.5-2.7). Finally, we found an association with lower parental education and adolescents' low adherence to Mediterranean diet (OR = 1.6, 95% CIs=1.0-2.4) and sleep problems (OR = 1.8, 95% CIs=1.0-3.0). Cluster analysis of health-related behaviours indicated the presence of two different clusters (unhealthy and healthy adolescents) that were associated with personality traits. Conscientiousness, extraversion, emotional instability and parental education are independent factors associated with the acquisition of adolescent healthy lifestyles.

Community disadvantage, inequalities in adolescent subjective well-being, and local social relations: The role of positive and negative social interactions

Studies identify the existence of inequalities in adolescent subjective well-being (SWB) across levels of community socio-economic disadvantage. One posited explanation is that community disadvantage harms SWB through undermining positive social relations among residents (often termed social capital). However, social relations can be both positive and negative; for example, social interactions between residents can be friendly or unfriendly, or involve being helped or harmed. Little work has explored negative social relations in communities and their impact on SWB. This study therefore examines the role that local negative social relations may play, alongside positive relations, in understanding inequalities in SWB across communities. Data are taken from a nationally representative survey of 16-17-year olds in England in 2015. Applying multilevel models, findings demonstrate that adolescents living in more disadvantaged communities exhibit lower SWB. In line with current theories, part of this association can be accounted for by weaker positive social relations: the results show that while positive local interactions are important for youth SWB (primarily via higher neighbour trust), young people in more disadvantaged communities report fewer local positive social interactions. However, the models also demonstrate that part of the negative association between community disadvantage and SWB is also accounted for by stronger negative social relations: the results show that negative local interactions are harmful for youth SWB (both directly, and indirectly via lower neighbour-trust), and young people in disadvantaged communities report more frequent negative local social interactions. Importantly, the negative indirect-effect of community disadvantage via increasing negative social interactions is almost twice as strong as the negative indirect-effect of disadvantage via reducing positive interactions. Taken together, community disadvantage appears to harm SWB not only by reducing positive relations but also increasing negative relations. These form dual, independent, social relations pathways through which community disadvantage affects SWB.

Youth Engagement, Positive Interethnic Contact, and 'Associational Bridges': A Quasi-Experimental Investigation of a UK National Youth Engagement Scheme

Affective interethnic ties are highly effective for improving out-group attitudes, especially during adolescence. Yet, young people face several obstacles to developing such ties in society. One potential means of fostering greater interethnic connectivity is through youth engagement: that is, formal, organized social participation in groups, clubs, or activities. However, little is still known about its effectiveness; especially for overcoming structural obstacles to contact in society, such as residential segregation. This study has two aims: to robustly examine whether youth engagement can build positive interethnic contact among young people; and, to perform the first systematic test of whether sites of engagement can act as “Associational Bridges”, providing greater opportunities for contact among youth from more segregated environments. To pursue these aims, the study exploited a unique data opportunity to perform a quasi-experimental analysis of a large-scale, nationally-implemented youth engagement scheme in the United Kingdom. The study uses pre-test/post-test data on N = 1371 participants (M_age = 16.7; 63% Female; 36% non-White) and N = 1946 propensity-score matched controls (M_age = 16.7; 62% Female; 36% non-White). Applying a (matched) difference-in-difference approach, the findings demonstrate that participation led to an increase in affective interethnic ties, which were evident at least 4–6 months after involvement had ended. Participation also had a stronger positive impact on youth from more residentially segregated areas: although joining the scheme with fewer interethnic ties, post-participation they reported just as many ties as their peers from less segregated areas. However, participation had no difference in effects for youth from more or less ethnically diverse areas. Youth engagement may thus be an effective tool for fostering positive contact; particularly among those from more segregated environments. However, attention should be paid to the design and recruitment practices of engagement programs to understand which structural barriers to contact in society they can overcome.
