Mental health literacy and academic performance (MHLAP) in high school students: a randomized clinical trial protocol

BACKGROUND

Mental health literacy is a promising avenue of intervention for addressing the development of psychopathology, as well as its associated consequences, such as a decrease in academic performance. The current study aims to test the effectiveness of such an intervention in high school students, focusing on two main formats of delivery: (1) automated and (2) blended.

METHODS

To achieve this aim, a randomized clinical trial with direct comparisons at three time points between three conditions (automated, blended, and waitlist) was designed. Power analyses yielded a necessary sample size of 264 high school students. The participants will be selected from Romanian high schools.

DISCUSSION

The current study aims to contribute to the mental health literacy literature by testing the effectiveness of an educational intervention concerning mental health in terms of its benefits for reducing psychopathology and increasing academic performance. The success of such an intervention bears important implications for addressing mental health in the educational system.

How to reduce anxiety symptoms through individual sport in youth: A longitudinal study over 8-month observation

Background

Anxiety symptoms are widely observed among the youth, and engagement in sports has been demonstrated to mitigate these symptoms. Nonetheless, the effectiveness of specific sports and the potential moderating role of psychological factors, such as self-esteem and self-efficacy, on the influence of sports on anxiety, remains to be elucidated. This study was designed to longitudinally assess the impact of sports participation on anxiety symptoms among young individuals.

Methods

The study encompassed 163 university students, with a male predominance of 81.6%, and explored the influence of sport-related factors (such as mastery of table tennis skills, level and engagement) and psychological aspects (including self-efficacy, self-esteem and resilience) on anxiety symptoms, employing an 8-month longitudinal approach. Physical activity, sedentary and sleep behaviour, along with age, body mass index (BMI), and sex, were accounted for as confounding variables.

Results

The study found that high table tennis performance score was found to buffer the development of anxiety symptoms in students with decreased self-esteem in an exploratory moderation model. Self-esteem and self-efficacy were negatively associated with the development of anxiety symptoms, whereas physical activity factors did not have a direct effect.

Conclusion

This study highlights the potential of table tennis as a form of sport to alleviate anxiety symptoms in university students, particularly among those with decreased self-esteem. Future research should address the study's limitations and explore the potential moderating effects of other psychological factors. Overall, these findings suggest a potential new approach to treating anxiety symptoms among university students.

Prevalence and incidence of personality disorders among children and adolescents in Danish mental health services: a nationwide register study

A few epidemiological studies have examined personality disorders (PDs) among children and adolescents in secondary mental health services. This study aims to describe the prevalence and incidence of PDs among children and adolescents who have attended Danish child and adolescent psychiatric services (CAPS). Using register-based data, we studied all patients under the age of 18 years who were admitted to in- and outpatient CAPS (N = 115,121) in Denmark from 2007 to 2017. A total of 4952 patients were diagnosed with a PD during the study period. The mean prevalence was 859 patients per year, and the mean incidence was 274 patients per year, including an increased incidence and prevalence of borderline, anxious, and unspecified PDs over the decade. The number of patients diagnosed with PDs increased from 700 to 851 per year, but the proportion of patients with PDs compared to all psychiatric diagnoses decreased from 4.2% to 2.8% over the study period. The PD population had an older age (14.8 years vs. 11.3 years; p < 0.001), a higher likelihood of being female (74% vs. 44%; p < 0.001), and four times more contacts with the psychiatric emergency departments than other patients with a psychiatric diagnosis. Future studies should focus on (a) implementing further epidemiological studies in different countries; (b) tracking diagnostic practices to facilitate comparisons and provide feedback for training clinicians and raising awareness; and (c) estimating trajectories of PDs, including costs within the CAPS, to facilitate informed decision-making regarding the future organization and provision of services to these children, adolescents, and their families.

Outcomes of Best-Practice Guided Digital Mental Health Interventions for Youth and Young Adults with Emerging Symptoms: Part I. A Systematic Review of Socioemotional Outcomes and Recommendations

Youth-specific digital mental health interventions (DMHI) represent an emerging field of study, and aim to increase access, improve socioemotional outcomes, and, where required, support triage to targeted interventions. However, prior reviews have reported inconsistent findings on the clinical effectiveness of such interventions in young adults (12-25 years). Further, shortfalls remain for the impact of guided interventions based on the mode of delivery and the type of human support personnel (e.g., professional or peer) guiding the intervention. In response, this systematic review, co-designed with Australia's leading mental health organization, aims to assess the effectiveness of guided digital programs in improving youth socioemotional outcomes. Included studies involve young people experiencing mental ill-health, receiving brief (i.e., 1-12 sessions), digitally delivered (at least partially) psychological interventions that were guided or partially guided, tested in a type of experimental study, with a socioemotional outcome. Specific socioemotional outcomes examined were depression, anxiety, stress, wellbeing, mindfulness, and quality of life. A systematic search of the contemporary published and grey literature identified 22,482 records with 32 relevant records published between 2018 and 2023. A narrative synthesis guided integration of findings. Results demonstrated strong evidence for the effectiveness of guided interventions on socioemotional outcomes (i.e., depression, anxiety, stress) yet these effects were short-lived. When factoring in the use of different control groups (i.e., active vs. inactive), inconsistent effects were observed for the socioemotional outcomes of depression, anxiety, and stress. The mode of delivery (i.e., asynchronous, synchronous, combined) and the type of human support personnel did not appear to impact socioemotional outcomes. Results indicate efficacious brief digital interventions for depression and anxiety include refresher/follow-up content, goal setting content, and relapse prevention content. In contrast, poor efficacy is associated with interventions that include homework tasks, self-monitoring, and log-keeping content.PROSPERO, ID CRD42023405812.

Mental disorders in former street-working boys

The continuity of mental disorders in street-working children is rarely studied. This study therefore investigated homotypic continuity, recurrence of the same disorder, and heterotypic continuity, when a new disorder follows on the previous, of mental disorders from childhood to adulthood in street-working boys from Duhok City, Kurdistan Region of Iraq. Mental disorders were assessed by structured diagnostic interviews in 40 street-working boys in 2004-2005 and again in 2021, when the participants' mean ages were 12.1 (SD 1.8) and 29.7 (SD 2.3), respectively. Mental disorders were common; 24 participants (60%) satisfied the criteria for at least one diagnosis at baseline and 28 (70%) at follow-up. Comorbidity increased from 1.2 (SD 1.4) disorders initially to 2.5 (SD 1.8) at follow-up. Only anxiety disorders showed homotypic continuity. Depressive disorders exhibited the greatest increase over time whereas externalizing disorders exhibited a decreasing tendency. The number of mental disorders in adulthood was related to the number of mental disorders in childhood but not to the number of childhood traumas experienced, having previously worked for more than two hours per day, having worked for over two years on the streets, or having at least one dead parent as a child. Parental ratings on the Child Behaviour Check List (CBCL) from childhood were also unrelated to the number of adult disorders. More longitudinal studies with bigger samples of both genders are needed to fully evaluate the continuity of mental disorders in street-working children and to determine whether the number of mental disorders in childhood is a stronger predictor of being mentally disordered in adult life than psychosocial risk factors or experiences of internalizing or externalizing symptoms in childhood.

Sex-specific associations between co-exposure to multiple metals and externalizing symptoms in adolescence and young adulthood

Externalizing disorders, such as attention-deficit/hyperactivity disorder (ADHD), account for the majority of the child/adolescent referrals to mental health services and increase risk for later-life psychopathology. Although the expression of externalizing disorders is more common among males, few studies have addressed how sex modifies associations between metal exposure and adolescent externalizing symptoms. This study aimed to examine sex-specific associations between co-exposure to multiple metals and externalizing symptoms in adolescence and young adulthood. Among 150 adolescents and young adults (55% female, ages: 15-25 years) enrolled in the Public Health Impact of Metals Exposure (PHIME) study in Brescia, Italy, we measured five metals (manganese (Mn), lead (Pb), copper (Cu), chromium (Cr), nickel (Ni)) in four biological matrices (blood, urine, hair, and saliva). Externalizing symptoms were assessed using the Achenbach System of Empirically Based Assessment (ASEBA) Youth Self-Report (YSR) or Adult Self Report (ASR). Using generalized weighted quantile sum (WQS) regression, we investigated the moderating effect of sex (i.e., assigned at birth) on associations between the joint effect of exposure to the metal mixture and externalizing symptoms, adjusting for age and socioeconomic status. We observed that metal mixture exposure was differentially associated with aggressive behavior in males compared to females (β = -0.058, 95% CI [-0.126, -0.009]). In males, exposure was significantly associated with more externalizing problems, and aggressive and intrusive behaviors, driven by Pb, Cu and Cr. In females, exposure was not significantly associated with any externalizing symptoms. These findings suggest that the effect of metal exposure on externalizing symptoms differs in magnitude between the sexes, with males being more vulnerable to increased externalizing symptoms following metal exposure. Furthermore, our findings support the hypothesis that sex-specific vulnerabilities to mixed metal exposure during adolescence/young adulthood may play a role in sex disparities observed in mental health disorders, particularly those characterized by externalizing symptoms.

Concussion Symptoms and Neurocognitive Performance of Children and Adolescents on Antidepressants

INTRODUCTION/PURPOSE

There is a well-established association between preexisting depression/anxiety and greater postconcussion symptom burden, but the potential impact of antidepressant medications has not been fully explored. The primary objective of this study was to compare preinjury/baseline and postinjury concussion symptom scores and neurocognitive performance of athletes on antidepressant medications, both with healthy controls and with those with depression/anxiety not on antidepressants.

METHODS

This is a cross-sectional study using data collected from 49,270 junior and high school athletes from computerized neurocognitive assessments (Immediate Post-Concussion Assessment and Cognitive Test [ImPACT]) administered between 2009 and 2018 held by the Massachusetts Concussion Management Coalition. The main outcome measures were symptom scores and neurocognitive performance measures, all of which were assessed both at baseline and postinjury. Statistical analysis included analysis of variance and Tukey pairwise comparisons for continuous variables and Fisher's exact test for categorical variables. Multivariate regression models were used to adjust for potential confounding variables.

RESULTS

Both at baseline and postinjury, athletes with depression/anxiety had mean total symptom scores that were more than double that of healthy controls regardless of antidepressant use. Although there were no significant differences in neurocognitive performance at baseline, depression/anxiety was associated with small but significant decreases in postinjury visual memory and visual motor scores.

CONCLUSIONS

Both at baseline and after sustaining a concussion, young athletes with depression/anxiety experience significantly greater symptom burden compared with healthy controls regardless of antidepressant use.

Navigating the Modern Landscape of Social Media: Ethical Considerations for Research With Adolescents and Young Adults

Engagement on social media among adolescents and young adults (AYAs) is almost universal. AYAs use social media for socialization, connection, and expression, as well as to obtain news and information. Adolescence and young adulthood also represent developmental periods characterized by the emergence of risk behaviors and many forms of psychopathology. Given that risk behaviors and mental health depictions are often displayed and observed online, social media platforms have become an optimal research tool to examine AYA behaviors that may not be visible offline. Social media platforms have the potential to increase recruitment and retention, especially among hard-to-reach, and understudied youth, and to connect AYA with resources for risk behaviors and mental health in a more naturalistic setting. Despite these advantages, the limited consensus on social media ethics across institutions and internal review boards, and the rapidly evolving features on each platform has made it difficult to develop study protocols, navigate and adapt to platform changes, and predict ethical issues that may arise in the context of research. Thus, the purpose of this manuscript is to discuss ethical considerations specific to AYA in social media research. Two research approaches, self-report and observational, are discussed with a focus on informed consent, privacy, and confidentiality. The goal of this manuscript is to highlight the nuances associated with social media research, and the implications for the promotion of ethical practices when adopting social media as a research tool to improve our understanding of AYA behavior.

Non-parental Childcare During Early Childhood and Problem Behaviour Trajectories from Ages 5 to 14 Years

Using data from the nationally representative Millennium Cohort Study, this study examined the association between age of starting and weekly hours in formal childcare between birth and 5 years with internalising and externalising behaviour trajectories from ages 5 to 14 years in England (N = 6194 children). Associations were analysed using multilevel general linear regression models, with adjustment for socio-economic position, maternal mental health, demographics, and child temperament. Later entry was associated with more internalising behaviours at age 14 years. Children who spent > 40 h per week in childcare between birth and 3 years displayed more externalising behaviour at 5 years than children who did not attend childcare. Controlling for socio-economic position and parental mental health attenuated findings.

Clinical effectiveness of drop-in mental health services at paediatric hospitals: A non-randomised multi-site study for children and young people and their families - study protocol

BACKGROUND

Despite the high prevalence of mental health difficulties in children and young people with long-term health conditions (LTCs), these difficulties and experiences are often overlooked and untreated. Previous research demonstrated the effectiveness of psychological support provided via a drop-in mental health centre located in a paediatric hospital. The aim of this prospective non-randomised single-arm multi-centre interventional study is to determine the clinical effectiveness of drop-in mental health services when implemented at paediatric hospitals in England.

METHODS

It is hypothesised that families who receive psychological interventions through the drop-in services will show improved emotional and behavioural symptoms. Outcomes will be measured at baseline and at 6-month follow-up. The primary outcome is the difference in the total difficulties score on the Strengths and Difficulties Questionnaire (SDQ) reported by parent or child at 6 months. Secondary outcomes include self and parent reported Paediatric Quality of Life Inventory (PedsQL), self-reported depression (PHQ-9) and anxiety measures (GAD-7) and family satisfaction (CSQ-8).

DISCUSSION

This trial aims to determine the clinical effectiveness of providing psychological support in the context of LTCs through drop-in mental health services at paediatric hospitals in England. These findings will contribute to policies and practice addressing mental health needs in children and young people with other long-term health conditions.

Fearlessness as an Underlying Mechanism Leading to Conduct Problems: Testing the INTERFEAR Model in a Community Sample in Spain

Conduct problems (CP) in childhood and adolescence have a significant impact on the individual, family, and community. To improve treatment for CP, there is a need to improve the understanding of the developmental pathways leading to CP in boys and girls. Prior research has linked the child's fearlessness and callous-unemotional (CU) traits, as well as experiences of parental warmth and punitive parenting, to CP. However, few studies have tested the interplay of these factors in contributing to future CP development. The present study aimed to test the InterFear model, which suggests that fearlessness in early childhood leads to CP through an indirect pathway involving low positive parenting, high negative/punitive parenting, and callous-unemotional (CU) traits. The sample included 2467 Spanish children (48.1% girls; Mage = 4.25; SD = 0.91), followed up across a five-year period. Besides a direct association between fearlessness in early childhood and future CP, the results found an indirect pathway whereby fearlessness reduces positive parenting and increases punitive parenting, which contributes to the development of CU traits and sets the stage for CP in later childhood. The specific indirect effect from fearlessness to CP via CU traits accounted for most of the variance, suggesting the existence of a temperamental pathway independent of parental variables. Further, two additional indirect pathways, exclusive of fearlessness, were identified, which started with low parental warmth and positive parenting, leading to CP via CU traits. These findings support the InterFear model, demonstrating multiple pathways to CP with the involvement of fearlessness, parenting practices, and CU traits. This model might play a pivotal role in the development of targeted prevention and intervention strategies for CP.

Mental health status among children and adolescents in one-child and multichild families: a meta-analysis of comparative studies

PURPOSE OF REVIEW

Controversy remains about the difference in mental health status among children and adolescents between one-child and multichild families in China. Thus, we conducted a meta-analysis of studies comparing mental health status between both groups and explored their potential moderating factors.

RECENT FINDINGS

Totally, 113 eligible studies encompassing 237 899 participants (one-child families: 83 125; multichild families: 154 774) were included. The pooled SMD of SCL-90 total score was -0.115 [95% confidence interval (95% CI): -0.152; -0.078; I2  = 86.9%]. Specifically, children and adolescents from one-child families exhibited lower scores in terms of somatization (SMD = -0.056; 95% CI: -0.087; -0.026), obsessive-compulsive symptoms (SMD = -0.116; 95% CI: -0.154; -0.079), interpersonal sensitivity (SMD = -0.140; 95% CI: -0.171; -0.109), depression (SMD = -0.123; 95% CI: -0.159; -0.088); anxiety (SMD = -0.121; 95% CI: -0.151; -0.092); phobic anxiety (SMD = -0.124; 95% CI: -0.166; -0.081); paranoid ideation (SMD = -0.040; 95% CI: -0.070; -0.009); and psychoticism (SMD = -0.119; 95% CI: -0.148; -0.089). Study publication year was significantly associated with differences in mental health status between both groups ( P  = 0.015).

SUMMARY

Children and adolescents from one-child families had better mental health status compared to those from multichild families in China. Future studies should investigate the underlying factors contributing to such mental health differences, and the potential interventions that could address these mental health problems.

Psychometric properties and normative data of the Latvian and Russian language versions of the strengths and difficulties questionnaire (SDQ) in the Latvian general adolescent population

OBJECTIVES

Mental health screening instruments are essential in population health research and clinical practice. The strengths and difficulties questionnaire (SDQ) self-report version has been widely used across the globe to screen for mental health problems in adolescent populations. This study aimed to explore the psychometric properties of the Latvian and Russian language versions of the SDQ in a representative sample of a general population of Latvian adolescents and establish the population-based normative scores.

MATERIALS AND METHODS

This analysis was based on data from the international Health Behaviour in School-aged Children study year 2017/2018 Latvian database. The sample comprised 2683 Latvian and 1321 Russian-speaking 11-, 13-, and 15-year-old adolescents.

RESULTS

Significant language-based variance was observed in the mean scores of the externalising subscales of the SDQ, with Latvian-speaking adolescents reporting higher levels of conduct problems and hyperactivity. The reliability was satisfactory (ordinal alpha >0.7) only for the prosocial behaviour, emotional, internalising problems, and total difficulties subscales, while conduct, hyperactivity, peer, and externalising problems scales demonstrated lower internal consistency (ordinal alpha 0.5-0.7). Confirmatory factor analysis (CFA) did not support the hypothesised narrow-band five-factor or broad-band three-factor structure of the SDQ. The normative banding scores were calculated for both language variants.

CONCLUSIONS

This study suggests that the self-report SDQ must be used cautiously in Latvian adolescents because some SDQ subscales lack reliability. When used in population research, the internalising subscales seem more reliable than the externalising ones. More research is needed regarding the reliability of the SDQ in clinical adolescent populations.

Promoting adolescent sleep and circadian function: A narrative review on the importance of daylight access in schools

Adolescent sleep disturbances and circadian delays pose significant challenges to mood and daytime functioning. In this narrative review, we explore the impact of light on sleep and highlight the importance of monitoring and managing light exposure in adolescents throughout the day and night. The benefits of daylight exposure in mitigating sleep and circadian disruptions are well-established; however, interventions targeting access to daylight in adolescents remain understudied and underutilized. The primary aim of this narrative review is to bring attention to this gap in the literature and propose the need for institutional-level interventions that promote access to daylight, especially considering adolescents' early school start times and substantial time spent indoors on weekdays. School-led interventions, such as active commuting to school and outdoor curriculums, have promising effects on sleep and circadian rhythms. Additionally, practical measures to optimize natural light in classrooms, including managing blinds and designing conducive environments, should also be considered. While future studies are necessary to facilitate the implementation of interventions, the potential for these school-level interventions to support adolescent sleep health is evident. Aiming for integration of individual-level regulation and institutional-level intervention of light exposure is necessary for optimal outcomes.

Association Between Parental Absence and Depressive Symptoms in Adolescence: Evidence From a National Household Longitudinal Survey

Longitudinal evidence demonstrating the association between parental absence and depressive symptoms in adolescence is limited. The present study aimed to explore this relationship in a Chinese national representative sample. This research was based on the China Family Panel Studies and included 1481 subjects. Depressive symptoms were assessed using the self-reported Center for Epidemiologic Studies Depression questionnaire. A multiple logistic regression model with a generalized estimating equation was used to test the association between parental absence and adolescent depressive symptoms. In the baseline year, 2012, 29.03% and 43.75% of adolescents had maternal and paternal absence, respectively. The prevalence of depressive symptoms increased from 23.23% to 28.12% in subsequent years. After controlling for covariates, maternal absence was positively associated with depressive symptoms (odds ratio 1.69, 95% confidence interval 1.06-2.68). Maternal absence led to depression in adolescents. It may be beneficial for adolescents with depression to spend more time with their mothers.

The Research on Risk Factors for Adolescents' Mental Health

There is a growing tendency for mental health disorders to emerge during adolescence. These disorders impair emotional, cognitive, and behavioral functioning, such as unsatisfying peer relationships, disruptive behavior, and decreased academic performance. They also contribute to vulnerability in later adulthood which negatively influences life-long well-being. Thus, research into etiology is imperative to provide implications for prevention and intervention within family and school practices. It is suggested that the onset of psychological disorders, such as depression and anxiety, is closely related to stress levels and patterns of stress reaction. Therefore, considerable research has investigated the link between hereditary factors, economic status, dispositional vulnerability, social relationships, and stress levels. The current study examines existing evidence and identifies multifaceted risk factors for adolescents' mental problems across three layers, including individual traits and personality, family status and practices, as well as peer relationships, and school climate. It is also suggested that factors from these three perspectives interact and are closely interconnected, directly or indirectly contributing to adolescent psychopathology. The implications for future development of prevention and intervention programs, as well as therapy, are discussed.

Association between pre-dementia psychiatric diagnoses and all-cause dementia is independent from polygenic dementia risks in the UK Biobank

BACKGROUND

Psychiatric disorders have been associated with higher risk for future dementia. Understanding how pre-dementia psychiatric disorders (PDPD) relate to established dementia genetic risks has implications for dementia prevention.

METHODS

In this retrospective cohort study, we investigated the relationships between polygenic risk scores for Alzheimer's disease (AD PRS), PDPD, alcohol use disorder (AUD), and subsequent dementia in the UK Biobank (UKB) and tested whether the relationships are consistent with different causal models.

FINDINGS

Among 502,408 participants, 9352 had dementia. As expected, AD PRS was associated with greater risk for dementia (odds ratio (OR) 1.62, 95% confidence interval (CI), 1.59-1.65). A total of 94,237 participants had PDPD, of whom 2.6% (n = 2519) developed subsequent dementia, compared to 1.7% (n = 6833) of 407,871 participants without PDPD. Accordingly, PDPD were associated with 73% greater risk of incident dementia (OR 1.73, 1.65-1.83). Among dementia subtypes, the risk increase was 1.5-fold for AD (n = 3365) (OR 1.46, 1.34-1.59) and 2-fold for vascular dementia (VaD, n = 1823) (OR 2.08, 1.87-2.32). Our data indicated that PDPD were neither a dementia prodrome nor a mediator for AD PRS. Shared factors for both PDPD and dementia likely substantially account for the observed association, while a causal role of PDPD in dementia could not be excluded. AUD could be one of the shared causes for PDPD and dementia.

INTERPRETATION

Psychiatric diagnoses were associated with subsequent dementia in UKB participants, and the association is orthogonal to established dementia genetic risks. Investigating shared causes for psychiatric disorders and dementia would shed light on this dementia pathway.

Technology-Enhanced BPT for Early-Onset Behavior Disorders: Improved Outcomes for Children With Co-Occurring Internalizing Symptoms

OBJECTIVE

Early-onset behavior disorders (BDs) are common and costly. The evidence-base for Behavioral Parent Training (BPT), the standard of care for early intervention for BDs in young children, is well-established; yet, common comorbidities such as internalizing symptoms are common and their impact, not well understood. The goal of the current study was to examine the potential for technology to improve BPT effects on observed parenting and child behavior outcomes for families of children recruited for clinically significant problem behavior who also presented with relatively higher internalizing symptoms.

METHOD

Families with low incomes (N = 101), who are overrepresented in statistics on early-onset BDs, were randomized to an evidence-based BPT program, Helping the Noncompliant Child (HNC), or Technology-Enhanced HNC (TE-HNC). Children were ages 3 to 8 years (55.4% were boys). Child race included White (64.0%), Black or African American (21.0%), more than one race (14.0%), and Hispanic/Latinx (13.9%).

RESULTS

Families in both groups evidenced improvement in internalizing symptoms at posttreatment; however, TE-HNC yielded the greatest improvement in positive parenting and child compliance at posttreatment and follow-up for children with the highest internalizing symptoms at baseline.

CONCLUSIONS

TE-HNC resulted in improved parenting and child behavior outcomes for children with elevated levels of co-occurring internalizing symptoms at baseline relative to standard HNC. We posit that these added benefits may be a function of TE-HNC, creating the opportunity for therapists to personalize the treatment model boosting parent skill use with more complex presentations, although a formal test of mediation will be important in future work.

Mental disorders and discrimination: A prospective cohort study of young twin pairs in Germany

Background

Mental disorders and perceived discrimination share common risk factors. The association between having a mental disorder and experiencing discrimination is well-known, but the extent to which familial factors, such as genetic and shared environmental factors, might confound this association, including sex differences in familial confounding, remains unexplored.

Aims

We investigated potential unmeasured familial confounding in the association between mental disorders and perceived discrimination using a matched twin study design.

Method

We examined data from 2044 same-sex twin pairs (n = 4088) aged 16-25 years from the German population-based study 'TwinLife'. We applied random-effects logistic regression to within-individual and within-and-between pair models of the association between mental disorder and perceived discrimination, and used likelihood ratio tests (LRTs) to compare these models. Multivariable models were adjusted for body mass index, educational attainment, and life satisfaction.

Results

There were 322 (8.1%) participants with a diagnosed mental disorder, and 15% (n = 604) of the cohort reported having experienced discrimination in the previous 12 months. Mental disorder and discrimination were associated in the adjusted within-individual model (adjusted odds ratio = 2.19, 95% confidence interval: 1.42-3.39, P<0.001). However, the within-and-between pair model showed that this association was explained by the within-pair mean (aOR = 4.24, 95% CI: 2.17-8.29, P<0.001) and not the within-pair difference (aOR = 1.26, 95% CI: 0.70-2.28, P = 0.4) of mental disorder. Therefore, this association was mostly explained by familial confounding, which is also supported by the LRTs for the unadjusted and adjusted models (P<0.001 and P = 0.03, respectively). This familial confounding was more prominent for males than females.

Conclusions

Our findings show that the association between mental disorder and discrimination is at least partially explained by unmeasured familial factors. Designing family-based healthcare models and incorporating family members in interventions targeted at ameliorating mental ill-health and experiences of discrimination among adolescents may improve efficacy.

Evaluation of Retinal Nerve Fiber Layer, Ganglion Cell Thickness, and Macular Thickness in Children With Comorbid Specific Learning Disorder and Attention-Deficit Hyperactivity Disorder

PURPOSE

To investigate the changes in ocular optical coherence tomography (OCT) findings in the comorbidity of attention-deficit hyperactivity disorder (ADHD) and specific learning disorder (SLD).

METHODS

This study included 40 individuals diagnosed as having ADHD along with comorbid SLD, 40 individuals diagnosed as having only ADHD, and 40 individuals with no psychiatric disorders. OCT assessments were performed on eyes of the participants to obtain retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, and macular thickness measurements.

RESULTS

In total, 240 eyes were evaluated. The right and left eyes were not significantly different in terms of RNFL, GCL, and macular thickness within groups (P > .05). RNFL thickness was measured and compared across four quadrants (superior, inferior, temporal, and nasal). Although these values were not significantly different between the groups (P > .05), RNFL was observed to be thinner in children with comorbid ADHD and SLD in all quadrants. Similarly, GCL and macular thickness measurements were also not different between the groups (P > .05).

CONCLUSIONS

Considering that retinal nerve fibers can be seen as an extension of the brain in the embryologic context, the results showed that OCT findings alone are not sufficient to detect the changes in ADHD and SLD comorbidity. The authors suggest that OCT is more useful in the etiology and follow-up of neurodegenerative diseases rather than neurodevelopmental disorders.

Leveraging the interpersonal context of child development to promote family resilience: A universal prevention approach from preconception through early childhood

Significant mental health problems affect one in five youth in the United States; in tandem with the child mental health epidemic, parents in the United States report high and rising rates of burnout and mental health challenges of their own. Multiple well-established theoretical perspectives demonstrate the high degree of interdependence between children's and their parents' mental health, including intergenerational transmission, prenatal programming, attachment, and temperament and self-regulation theories. Drawing on these perspectives, we argue that a universal prevention approach that centers the development of psychopathology within the context of the parent-child dyad can promote resilience and arrest emerging mental health problems for children and their parents, during sensitive developmental windows (e.g., preconception through early childhood). Derived from this integrated theoretical framework, we review empirical support for the following targets to promote family resilience: screening for current and historical parent risk factors and resilience resources; strengthening healthy, reciprocal social ties; and supporting youth socioemotional skill acquisition. Our review of the literature highlights how improvements in these areas can have cascading benefits across development, for both parents and their children, as well as for future generations. We conclude with actionable, empirically-supported recommendations that can have profound impacts on these targets through changes in federal and state policies, community healthcare settings, and early childhood education and care programs. To achieve enduring, multigenerational impacts, societal and community-level policies, programs, and practices must interweave efforts to support child mental health with efforts to promote parent adjustment and wellbeing.

Incidence of mental health conditions following pediatric hospital admissions: analysis of a national database

Introduction

Despite increasing survival of children following hospitalization, hospitalization may increase iatrogenic risk for mental health (MH) disorders, including acute stress, post-traumatic stress, anxiety, or depression. Using a population-based retrospective cohort study, we assessed the rates of new MH diagnoses during the 12 months after hospitalization, including the moderating effects of ICU exposure.

Study design/methods

This was a retrospective case control study using the Truven Health Analytics insurance database. Inclusion criteria included children aged 3-21 years, insurance enrollment for >12 months before and after hospital admission. We excluded children with hospitalization 2 years prior to index hospitalization and those with prior MH diagnoses. We extracted admission type, ICD-10 codes, demographic, clinical, and service coordination variables from the database. We established age- and sex-matched cohorts of non-hospitalized children. The primary outcome was a new MH diagnosis. Multivariable regression methods examined the risk of incident MH disorder(s) between hospitalized and non-hospitalized children. Among hospitalized children, we further assessed effect modification from ICU (vs. non-ICU) stay, admission year, length of stay, medical complexity, and geographic region.

Results

New MH diagnoses occurred among 19,418 (7%) hospitalized children, 3,336 (8%) ICU-hospitalized children and 28,209 (5%) matched healthy controls. The most common MH diagnoses were anxiety (2.5%), depression (1.9%), and stress/trauma (2.2%) disorders. Hospitalization increased the odds of new MH diagnoses by 12.3% (OR: 1.123, 95% CI: 1.079-1.17) and ICU-hospitalization increased these odds by 63% (OR: 1.63, 95% CI: 1.483-1.79) as compared to matched, non-hospitalized children. Children with non-complex chronic diseases (OR: 2.91, 95% CI: 2.84-2.977) and complex chronic diseases (OR: 5.16, 95% CI: 5.032-5.289) had a substantially higher risk for new MH diagnoses after hospitalization compared to patients with acute illnesses.

Conclusion

Pediatric hospitalization is associated with higher, long-term risk of new mental health diagnoses, and ICU hospitalization further increases that risk within 12 months of the acute episode. Acute care hospitalization confers iatrogenic risks that warrant long-term mental and behavioral health follow-up.

Across ages and places: Unpredictability of maternal sensory signals and child internalizing behaviors

BACKGROUND

Patterns of sensory inputs early in life play an integral role in shaping the maturation of neural circuits, including those implicated in emotion and cognition. In both experimental animal models and observational human research, unpredictable sensory signals have been linked to aberrant developmental outcomes, including poor memory and effortful control. These findings suggest that sensitivity to unpredictable sensory signals is conserved across species and sculpts the developing brain. The current study provides a novel investigation of unpredictable maternal sensory signals in early life and child internalizing behaviors. We tested these associations in three independent cohorts to probe the generalizability of associations across continents and cultures.

METHOD

The three prospective longitudinal cohorts were based in Orange, USA (n = 163, 47.2 % female, Mage = 1 year); Turku, Finland (n = 239, 44.8 % female, Mage = 5 years); and Irvine, USA (n = 129, 43.4 % female, Mage = 9.6 years). Unpredictability of maternal sensory signals was quantified during free-play interactions. Child internalizing behaviors were measured via parent report (Orange & Turku) and child self-report (Irvine).

RESULTS

Early life exposure to unpredictable maternal sensory signals was associated with greater child fearfulness/anxiety in all three cohorts, above and beyond maternal sensitivity and sociodemographic factors. The association between unpredictable maternal sensory signals and child sadness/depression was relatively weaker and did not reach traditional thresholds for statistical significance.

LIMITATIONS

The correlational design limits our ability to make causal inferences.

CONCLUSIONS

Findings across the three diverse cohorts suggest that unpredictable maternal signals early in life shape the development of internalizing behaviors, particularly fearfulness and anxiety.

Maternal autistic traits and anxiety in children with typical development in Chinese families: a moderated mediation model of mothers' negative emotional expressions and child gender

Background

Prior studies have focused on the effects of maternal autistic traits on children with autism, but little attention has been paid to the effects of maternal autistic traits on typically developing children, while the mechanisms of the effects are not clear.

Objective

Given that, a moderated mediation model was conducted to examine the association between maternal autistic traits and typically developing children's anxiety and the underlying mechanisms.

Methods and results

Participants were 648 mother-child dyads in which these children had no autistic siblings. Mothers reported their autistic traits and negative emotional expressions in the family and children's anxiety. The results indicated that children's anxiety was predicted by maternal autistic traits. Mediating analysis revealed that mothers' negative emotional expressions partially mediated the association between their autistic traits and children's anxiety. The findings also indicated that child gender moderated the relationship between maternal emotional expressions and children's anxiety. Specifically, anxiety in girls was more strongly predicted by negative emotional expressions from their mothers than in boys.

Conclusion

These results have important theoretical and practical implications for reducing the adverse effect of maternal autistic traits on children's anxiety, especially for girls. The present study also reveals that maternal negative emotional expression is an important mechanism. Causal conclusions cannot be drawn based on cross-sectional research design, so it is necessary to conduct longitudinal studies in the future.

Effectiveness of Online and Remote Interventions for Mental Health in Children, Adolescents, and Young Adults After the Onset of the COVID-19 Pandemic: Systematic Review and Meta-Analysis

BACKGROUND

The prevalence of mental illness increased in children, adolescents, and young adults during the COVID-19 pandemic, while at the same time, access to treatment facilities has been restricted, resulting in a need for the quick implementation of remote or online interventions.

OBJECTIVE

This study aimed to give an overview of randomized controlled studies examining remote or online interventions for mental health in children, adolescents, and young adults and to explore the overall effectiveness of these interventions regarding different symptoms.

METHODS

A systematic literature search was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines using PubMed, PsycInfo, Psyndex, Embase, and Google Scholar. A meta-analysis was conducted using a random effects model to calculate overall effect sizes for interventions using standardized mean differences (SMDs) for postintervention scores.

RESULTS

We identified 17 articles with 8732 participants in the final sample, and 13 were included in the quantitative analysis. The studies examined different digital interventions for several outcomes, showing better outcomes than the control in some studies. Meta-analyses revealed significant medium overall effects for anxiety (SMD=0.44, 95% CI 0.20 to 0.67) and social functioning (SMD=0.42, 95% CI -0.68 to -0.17) and a large significant effect for depression (SMD=1.31, 95% CI 0.34 to 2.95). In contrast, no significant overall treatment effects for well-being, psychological distress, disordered eating, and COVID-19-related symptoms were found.

CONCLUSIONS

The qualitative and quantitative analyses of the included studies show promising results regarding the effectiveness of online interventions, especially for symptoms of anxiety and depression and for training of social functioning. However, the effectiveness needs to be further investigated for other groups of symptoms in the future. All in all, more research with high-quality studies is required.

Longitudinal Associations Between Pet Relationship Quality and Socio-Emotional Functioning in Early Adolescence

Adolescence is a key developmental period for socio-emotional skills, and companion animal relationships may be one potential source of emotional support and resilience during this time. This study used longitudinal data from 940 pet-owning adolescents, collected over four time points, from youth in the Northeastern United States. We assessed whether pet relationship quality (indexed by relationship satisfaction, companionship, and emotional disclosure) predicted trajectories of loneliness, social anxiety, and depression. Results indicated that high satisfaction with a pet relationship was associated with more favorable trajectories, but companionship (i.e., regarding frequency of interacting with the pet) was not related significantly to socio-emotional functioning. High levels of disclosure to a pet were linked with less favorable trajectories for loneliness and depression, but not related to social anxiety. These results suggest that a pet relationship can, in some cases, be associated positively with socio-emotional development, but that there is significant complexity in these associations. Families, educators, and practitioners should take a nuanced approach to understanding individual adolescent-pet relationships as a contextual asset for specific youth.

Preschoolers and anxiety: The effect of parental characteristics

PROBLEM

Anxiety is a common phenomenon among children that can lead to adverse developmental outcomes. A challenging parent-child relationship and its characteristics may negatively impact the development of a child's internalizing problems. However, theoretical models on children's anxiety have not fully emphasized the contribution of parenting and environmental factors. Therefore, the aim of this study is to explore the possible correlations between parenting styles and other parental characteristics with children's anxiety.

METHODS

The sample consisted of 443 parents of preschool children who completed the Parenting Styles and Dimension Questionnaire and the Child Behavior Checklist 1.5-5. The univariate analysis included differences between demographic groups, assessed with independent sample t-tests. Associations between demographic evidence and child anxiety were estimated using χ2 tests. Binomial logistic regression analysis assessed the most important parenting characteristics contributing to a child's anxiety.

FINDINGS

A total of 24.6% of the children had borderline or clinical symptoms of anxiety. Parents whose children were anxious were more permissive than parents of nonanxious children (p < 0.001). Mothers were more authoritative compared to fathers. In addition, permissive parenting style increased the probability of a child's anxiety and maternal permissive style emerged as a significant predictor of anxiety in preschoolers (p < 0.003).

CONCLUSIONS

This study revealed that the permissive parenting style is associated with anxiety in preschool children. Furthermore, the maternal permissive style was identified as a predictor of anxiety. Future research may address its causal effect on anxiety and other behavioral problems, focusing on multiple perspective relationships and cultural dimensions.

Profiles of interpersonal relationship qualities and trajectories of internalizing problems among Chinese adolescents

Adolescence is a significant period for the formation of relationship networks and the development of internalizing problems. With a sample of Chinese adolescents (N = 3,834, 52.01% girls, Mage = 16.68 at Wave 1), the present study aimed to identify the configuration of adolescents' relationship qualities from four important domains (i.e., relationship quality with mother, father, peers, and teachers) and how distinct profiles were associated with the development of internalizing problems (indicated by depressive and anxiety symptoms) across high school years. Latent profile analysis identified a five-profile configuration with four convergent profiles (i.e., relationship qualities with others were generally good or bad) and one "Father estrangement" profile (i.e., the relationship quality with others were relatively good but that with father was particularly poor). Further conditional latent growth curve analysis indicated the "Father estrangement" profile was especially vulnerable to an increase in the internalizing problems as compared with other relationship profiles. This study contributes to understanding the characteristics of interpersonal relationship qualities and their influences on adolescent internalizing problems in a non-Western context. Results were further discussed from a culturally specific perspective.

Autism Spectrum Disorder and Anxiety Among Transgender Youth: Use of the Social Communication Questionnaire (SCQ)

Autism spectrum disorder (ASD) and ASD symptoms are overrepresented among gender-diverse youth across studies. Gender-diverse and ASD youth are at risk for anxiety, but anxiety is unclear among gender-diverse youth with ASD. The Social Communication Questionnaire (SCQ) is a commonly used ASD screener, including in multidisciplinary gender-affirming programs, but scholars have disagreed on the most optimal cut-off score. To date, no study has investigated the sensitivity and specificity of its established cut-off score of 15 with a sample of transgender youth. Gaining more accurate information about the utility of ASD screening tools with gender diverse youth is critical in order to help refer youth to needed services. Among a sample of 325 transgender youth, this study sought to determine an optimal cut-off score for the SCQ, the prevalence of ASD and ASD symptoms, and the relationship between ASD and anxiety within this population. The current study found that a lower cut-off score of 11 yielded optimal sensitivity and specificity (i.e., the best balance of accurately identifying individuals with ASD based on the screener), and analyses found an overrepresentation of ASD (5.2%) and ASD traits (12.1%). Transgender youth with ASD or ASD symptoms had higher anxiety, and all youth perceived themselves as more anxious than their parents. Future research is needed to identify the needs of this population, with particular consideration for the lived experiences of gender diverse and transgender youth.

Implementation of an Electronic Mental Health Platform for Youth and Young Adults in a School Context Across Alberta, Canada: Thematic Analysis of the Perspectives of Stakeholders

BACKGROUND

Youth, aged 15 to 24 years, are more likely to experience mental health (MH) or substance use issues than other age groups. This is a critical period for intervention because MH disorders, if left unattended, may become chronic and serious and negatively affect many aspects of a young person's life. Even among those who are treated, poor outcomes will still occur for a percentage of youth. Electronic MH (eMH) tools have been implemented in traditional MH settings to reach youth requiring assistance with MH and substance use issues. However, the utility of eMH tools in school settings has yet to be investigated.

OBJECTIVE

The objective of this study was to gain an understanding of the perspectives of key school staff stakeholders regarding barriers and facilitators to the implementation of the Innowell eMH platform in secondary schools across the province of Alberta, Canada.

METHODS

Guided by a qualitative descriptive approach, focus groups were conducted to elicit stakeholder perspectives on the perceived implementation challenges and opportunities of embedding the Innowell eMH platform in secondary school MH services. In total, 8 focus groups were conducted with 52 key school staff stakeholders.

RESULTS

Themes related to barriers and facilitators to youth and school MH care professional (MHCP) capacity in implementing and using eMH tools were identified. With respect to youth capacity barriers, the following themes were inductively generated: (1) concerns about some students not being suitable for eMH services, (2) minors requiring consent from parents or caregivers to use eMH services as well as confidentiality and privacy concerns, and (3) limited access to technology and internet service among youth. A second theme related to school MHCP barriers to implementation, which included (1) feeling stretched with high caseloads and change fatigue, (2) concerns with risk and liability, and (3) unmasking MH issues in the face of limited resources. In contrast to the barriers to youth and MHCP capacity, many facilitators to implementation were discussed. Youth capacity facilitators included (1) the potential for youth to be empowered using eMH tools, (2) the platform fostering therapeutic relationships with school personnel, and (3) enhancing access to needed services and resources. MHCP capacity facilitators to implementation were (1) system transformation through flexibility and problem-solving, (2) opportunities for collaboration with youth and MHCPs and across different systems, and (3) an opportunity for the continuity of services.

CONCLUSIONS

Our findings highlight nuanced school MHCP perspectives that demonstrate critical youth and MHCP capacity concerns, with consideration for organizational factors that may impede or enhance the implementation processes for embedding eMH in a school context. The barriers and facilitators to implementation provide future researchers and decision makers with challenges and opportunities that could be addressed in the preimplementation phase.

[Sports and Physical Exercise Therapy in the Treatment of Mental Health Issues in Children and Adolescents]

Sports and Physical Exercise Therapy in the Treatment of Mental Health Issues in Children and Adolescents Abstract: Mental disorders are among the most common chronic diseases in childhood and adolescence in Germany and worldwide. The health benefits of a physically active lifestyle during adolescence are well documented. Furthermore, a growing body of evidence suggests a positive impact of physical activity on mental health and emotional well-being. Longitudinal studies also show an association between physical activity and reduced risk of developing a mental disorder. Therefore, therapeutic exercise plays an important role in child and adolescent psychiatry. High-quality randomized-controlled trials are needed to substantiate the described effects.

Mindfulness-enhanced parenting programmes for improving the psychosocial outcomes of children (0 to 18 years) and their parents

BACKGROUND

Emotional and behavioural difficulties (EBD) in children are common, characterised by externalising or internalising behaviours that can be highly stable over time. EBD are an important cause of functional disability in childhood, and predictive of poorer psychosocial, academic, and occupational functioning into adolescence and adulthood. The prevalence, stability, and long-term consequences of EBD highlight the importance of intervening in childhood when behavioural patterns are more easily modified. Multiple factors contribute to the aetiology of EBD in children, and parenting plays an important role. The relationship between parenting and EBD has been described as bidirectional, with parents and children shaping one another's behaviour. One consequence of bidirectionality is that parents with insufficient parenting skills may become involved in increasingly negative behaviours when dealing with non-compliance in children. This can have a cyclical effect, exacerbating child behavioural difficulties and further increasing parental distress. Behavioural or skills-based parenting training can be highly effective in addressing EBD in children. However, emotional dysregulation may intercept some parents' ability to implement parenting skills, and there is recognition that skills-based interventions may benefit from adjunct components that better target parental emotional responses. Mindful parenting interventions have demonstrated some efficacy in improving child outcomes via improvements in parental emotion regulation, and there is potential for mindfulness training to enhance the effectiveness of standard parent training programmes.

OBJECTIVES

To assess the effectiveness of mindfulness-enhanced parent training programmes on the psychosocial functioning of children (aged 0 to 18 years) and their parents.

SEARCH METHODS

We searched the following databases up to April 2023: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL Plus, PsycINFO, Sociological Abstracts, Social Sciences Citation Index, Conference Proceedings Citation Index - Social Science & Humanities, AMED, ERIC, ProQuest Dissertations & Theses, Cochrane Database of Systematic Reviews, Campbell Collaboration Library of Systematic Reviews, as well as the following trials registers: ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). We also contacted organisations/experts in the field.

SELECTION CRITERIA

We included randomised and quasi-randomised trials. Participants were parents or caregivers of children under the age of 18. The intervention was mindfulness-enhanced parent training programmes compared with a no-intervention, waitlist, or attentional control, or a parent training programme with no mindfulness component. The intervention must have combined mindfulness parent training with behavioural or skills-based parent training. We defined parent training programmes in terms of the delivery of a standardised and manualised intervention over a specified and limited period, on a one-to-one or group-basis, with a well-defined mindfulness component. The mindfulness component must have included mindfulness training (breath, visualisation, listening, or other sensory focus) and an explicit focus on present-focused attention and non-judgemental acceptance.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane procedures.

MAIN RESULTS

Eleven studies met our inclusion criteria, including one ongoing study. The studies compared a mindfulness-enhanced parent training programme with a no-treatment, waitlist, or attentional control (2 studies); a parent training programme with no mindfulness component (5 studies); both a no-treatment, waitlist, or attentional control and a parent training programme with no mindfulness component (4 studies). We assessed all studies as being at an unclear or high risk of bias across multiple domains. We pooled child and parent outcome data from 2118 participants to produce effect estimates. No study explicitly reported on self-compassion, and no adverse effects were reported in any of the studies. Mindfulness-enhanced parent training programmes compared to a no-treatment, waitlist, or attentional control Very low certainty evidence suggests there may be a small to moderate postintervention improvement in child emotional and behavioural adjustment (standardised mean difference (SMD) -0.46, 95% confidence interval (CI) -0.96 to 0.03; P = 0.06, I2 = 62%; 3 studies, 270 participants); a small improvement in parenting skills (SMD 0.22, 95% CI 0.06 to 0.39; P = 0.008, I2 = 0%; 3 studies, 587 participants); and a moderate decrease in parental depression or anxiety (SMD -0.50, 95% CI -0.96 to -0.04; P = 0.03; 1 study, 75 participants). There may also be a moderate to large decrease in parenting stress (SMD -0.79, 95% CI -1.80 to 0.23; P = 0.13, I2 = 82%; 2 studies, 112 participants) and a small improvement in parent mindfulness (SMD 0.21, 95% CI -0.14 to 0.56; P = 0.24, I2 = 69%; 3 studies, 515 participants), but we were not able to exclude little to no effect for these outcomes. Mindfulness-enhanced parent training programmes compared to parent training with no mindfulness component Very low certainty evidence suggests there may be little to no difference postintervention in child emotional and behavioural adjustment (SMD -0.09, 95% CI -0.58 to 0.40; P = 0.71, I2 = 64%; 5 studies, 203 participants); parenting skills (SMD 0.13, 95% CI -0.16 to 0.42; P = 0.37, I2 = 16%; 3 studies, 319 participants); and parent mindfulness (SMD 0.11, 95% CI -0.19 to 0.41; P = 0.48, I2 = 44%; 4 studies, 412 participants). There may be a slight decrease in parental depression or anxiety (SMD -0.24, 95% CI -0.83 to 0.34; P = 0.41; 1 study, 45 participants; very low certainty evidence), though we cannot exclude little to no effect, and a moderate decrease in parenting stress (SMD -0.51, 95% CI -0.84 to -0.18; P = 0.002, I2 = 2%; 3 studies, 150 participants; low certainty evidence).

AUTHORS' CONCLUSIONS

Mindfulness-enhanced parenting training may improve some parent and child outcomes, with no studies reporting adverse effects. Evidence for the added value of mindfulness training to skills-based parenting training programmes is suggestive at present, with moderate reductions in parenting stress. Given the very low to low certainty evidence reviewed here, these estimates will likely change as more high-quality studies are produced.

Mindfulness Training Enhances Students' Executive Functioning and Social Emotional Skills

More research is needed to understand the effects of school-based mindfulness programs in the years before adolescence, which represent a critical juncture and transitional period of development. The present study investigated mindfulness with elementary school students using random assignment and objective measures. The sample included 292 5th graders from 21 classrooms randomly assigned to an 8-week mindfulness training or wait-list control group. Students were assessed at pre- and post-intervention on behavioral measures of executive functioning and teacher-rated social emotional competence, along with end of year social-emotional learning report card grades. Analyses using hierarchal linear modeling found that students in the intervention group demonstrated significant gains on a computerized task of cognitive flexibility, and end of year social-emotional learning grades controlling for prior year grades, but not teacher reported social emotional competence. Taken together these findings point to a simple, yet promising method for bolstering students' cognitive and social emotional skills.

Reasons for non-participation of children and adolescents in a large-scale school-based mental health project

Background

Non-participation in mental health studies is an under-explored but very important topic. Investigating reasons for non-participation holds promise for the planning of future study designs and recruitment strategies. This study aimed at investigating reasons for children and adolescents (C&A) not participating in a school-based mental health research project.

Methods

Data collection took place within the school-based recruitment of a large-scale multi-site project ("ProHEAD-Promoting Help-seeking using E-technology for Adolescents") in Germany. Participants were N = 534 C&A aged ≥ 12 years attending secondary schools. The present cross-sectional study analyzed anonymous survey data of C&A who themselves or whose parents, respectively, did not provide written consent to participate in the mental health research project. The questionnaire consisted of 14 items covering potential reasons for non-participation, and four free text fields. Besides descriptive statistics, free text field answers were analyzed using qualitative content analysis.

Results

Students indicated an average of M = 2.94 (SD = 1.75) reasons for their non-participation in the project. In the descriptive analysis of indicated items, the three most frequently reported reasons for non-participation included students reporting to not be concerned by the topic "mental health" (n = 290, 54.3%), not having returned the consent form to the teacher (n = 175, 32.8%), and not having time for participation (n = 149, 27.9%). In the qualitative content analysis, the most frequently assigned categories were organizational reasons (n = 216, 57.1%), general disinterest in study participation (n = 139, 36.8%), and personal attitudes toward the topic "mental health" (n = 84, 22.2%), such as not being concerned with the topic "mental health" (n = 23, 6.1%) or being too concerned with the topic "mental health" (n = 16, 4.2%).

Conclusion

The study provides unique insights into reasons for C&A and their caregivers not participating in a large federally funded mental health research project. The results suggest that in order to increase participation rates, stigma should be reduced, parents as well as teachers should be involved where possible, and the use of incentives might be helpful. The study highlights the importance of assessing reasons for non-participation, especially in online intervention studies on mental health.

Psychometric properties of the Distress Questionnaire-5 (DQ5) for measuring psychological distress in adolescents

Screening for psychological distress may assist in identifying at-risk adolescents. While several measures of adolescent psychological distress have been used, most have limited or suboptimal psychometric properties. This study aimed to assess the psychometric properties of the Distress Questionnaire-5 (DQ5), a brief measure of psychological distress, in a large community-based sample of adolescents. Data for the study (n = 3117) were drawn from the baseline and 6-week follow-up assessments of the Future Proofing Study, which collected data from three cohorts of Year 8 students (M = 13.9 years; 48% female) between August 2019 and May 2022. Participants completed the DQ5 at each measurement occasion, as well as measures of depression, generalised and social anxiety, and suicidal ideation. The DQ5 had good fit to a unidimensional construct, with standardised factor loadings ranging between 0.69 and 0.90. The scale had strong criterion (AUC ranged from 0.84 to 0.93) and predictive (AUC ranged from 0.81 to 0.87) validity when compared against indicators for depression, generalised anxiety, social anxiety and suicidal ideation. The DQ5 cut-point of ≥14 had 80% sensitivity and 90% specificity for identifying adolescents meeting symptom thresholds for any of the assessed mental health conditions. Changes in DQ5 scores over 6 weeks had moderate associations with changes in other symptom scales, suggesting sensitivity to change. In conclusion, the DQ5 demonstrates strong psychometric properties and is a reliable measure of psychological distress in adolescents. Given its brevity and ease of interpretation, the DQ5 could be readily used in schools to screen for psychological distress in students.

Depressive Symptoms and Their Longitudinal Impact on Physical Activity and Sedentary Behaviors Among Mexican-Heritage Youth

The purpose of this study is to examine the longitudinal impact of depressive symptoms on physical activity (PA) levels, sedentary behavior, and screen time among first-generation, Mexican-heritage youth. Mexican-heritage families were recruited by promotoras de salud from colonias in Hidalgo County, Texas. Participants (n = 200 youth, 116 families in final sample) completed at-home, interviewer-administered surveys once during the summer (June-July) and once during the fall (August-December). Youth PA and sedentary behaviors were assessed using a validated 7-day recall instrument. The validated Center for Epidemiology Studies-Depression Child scale was used to assess depression symptoms. Linear mixed-effects models were used to analyze the relationships of PA and sedentary behavior with depressive symptoms. Results showed that those depression symptoms were significantly associated with decreased number of self-reported minutes of sitting and screen time over time in the full sample and among male youth. Depression symptoms also significantly decreased the number of self-reported active and moderate to vigorous PA minutes over time among male youth. Researchers can build on our findings by identifying the mechanisms driving the relationships between depression and PA/sedentary behavior. Public health-programing efforts should intentionally consider the impact that depressive symptoms have on PA.

Expectations and perspectives of cognitive behavioural therapy for childhood anxiety and related disorders

BACKGROUND

Anxiety disorders are the most frequently diagnosed psychiatric conditions in children and adolescents. Cognitive behavioural therapy (CBT) is a well-established and effective treatment for anxiety and related disorders across the lifespan. Expectations of psychotherapy have been demonstrated to affect outcomes, yet there is sparse existing literature on adolescent patient and parent perspectives of CBT prior to engagement with treatment.

AIMS

This study aimed to qualitatively explore the expectations and perceptions of CBT for anxiety and related disorders among adolescent patients and parents.

METHOD

Fourteen adolescent patients and 16 parents participated in semi-structured individual interviews or focus groups consisting of 2-3 participants. Interview transcripts were analysed using inductive analysis.

RESULTS

Three themes were identified: worries about CBT, expectations and knowledge of the CBT process, and the role of parents and families. Overall, we found that adolescents and parents had generally positive views of CBT. The outset of CBT saw adolescents and parents express concern about stigma as well as the ambiguity of CBT. Parents continued to express a lack of understanding of what CBT entailed during their child's treatment course.

CONCLUSION

These results suggest that both adolescents and parents would benefit from early discussion and reinforcement of expectations for CBT treatment. Further research efforts are warranted and should be directed towards determining appropriate expectations for parental involvement in a child's CBT course and effective communication of treatment expectations to both adolescents and parents.

Caregiver adverse childhood experiences and preschool externalizing problems: The role of factors that contribute to caregiver resilience

BACKGROUND

Preschool children with externalizing problems are at risk for short- and long-term difficulties and preschool externalizing problems (PEP) are influenced by several caregiver factors. One such factor is caregiver adverse childhood experiences (ACEs). Researchers have investigated how caregiver ACEs are related to PEP by identifying risk factors to account for this association. However, research on caregiver factors associated with fewer PEP is limited. Particularly, factors that contribute to caregiver resilience may be adaptive caregiver characteristics that negatively relate to PEP, even when adjusting for caregiver ACEs.

OBJECTIVE

The present study sought to address a gap in the literature by examining the impact of different types of factors that contribute to caregiver resilience (e.g., caregiver social-ecological factors or caregiver positive childhood experiences) as promotive factors of lower PEP.

PARTICIPANTS AND SETTING

Participants included 125 caregiver-child dyads recruited from the community.

METHOD

Participating caregivers completed measures of their own and their child's demographic information, caregiver ACEs, caregiver social-ecological factors, caregiver positive childhood experiences, and PEP.

RESULTS

Overall, positive caregiver childhood experiences (r = -0.25, p < .01), and not caregiver social-ecological factors (r = -0.13, p = .15), demonstrated a significant negative association with PEP. However, this relation became statistically non-significant when adjusting for caregiver ACEs (β = -0.12, p = .20).

CONCLUSIONS

Given the association between caregiver ACEs and PEP, this study highlights the importance of assessing a caregiver's ACEs, specifically when working with caregivers seeking parent training for disruptive child behaviors. There should be a continued focus on ecological and family strengths and differential impacts as they relate to PEP.

The burden of psychological distress and unhealthy dietary behaviours among 222,401 school-going adolescents from 61 countries

We aimed to calculate the sex-specific prevalence of psychological distress and unhealthy eating habits among adolescents across countries and regions, and to explore their potential associations. We used data from the Global School-Based Health Survey (GSHS) for 61 countries. Psychological distress was defined based on the existence of ≥ 2 factors from the following: loneliness, anxiety, suicide ideation, suicide planning, and suicide attempt. Four unhealthy dietary behaviours were examined: inadequate fruit intake, inadequate vegetable intake, daily consumption of soft drinks, and weekly fast-food consumption. We used random-effects meta-analysis to estimate the overall and regional pooled prevalence. Mixed-effect multilevel logistic regressions were used to estimate adjusted odds ratios (aORs) of unhealthy dietary behaviours in relation to psychological distress. Among 222,401 school-going adolescents (53.3% girls), the prevalence of psychological distress was 17.9%, with girls reporting higher than boys (20.8% vs. 14.9%). Adolescents in the African region reported the highest prevalence (22.5%), while those in the South-East Asia region reported the lowest (11.3%). The prevalence of inadequate fruit intake, inadequate vegetable intake, daily soft drink consumption, and weekly fast-food consumption was 37.0%, 28.5%, 50.0%, and 57.4% respectively. Psychological distress was associated with inadequate fruit intake (pooled aOR = 1.19, 95% CI 1.17-1.23), inadequate vegetable intake (pooled OR = 1.19, 1.16-1.22), daily consumption of soft drinks (pooled aOR = 1.14, 1.12-1.17), and weekly consumption of fast food (pooled aOR = 1.12, 1.09-1.15). Our findings indicate a substantial variance in the burden of psychological distress and unhealthy dietary behaviours across different regions. Adolescents experiencing psychological distress were more likely to have unhealthy dietary habits.

Serum Biomarkers to Mild Cognitive Deficits in Children and Adolescents

Intellectual disability (ID) is a condition characterized by significant limitations in both cognitive development and adaptive behavior. The diagnosis is made through clinical assessment, standardized tests, and intelligence quotient (IQ). Genetic, inflammation, oxidative stress, and diet have been suggested to contribute to ID, and biomarkers could potentially aid in diagnosis and treatment. Study included children and adolescents aged 6-16 years. The ID group (n = 16) and the control group (n = 18) underwent the Wechsler Intelligence Scale for Children (WISC-IV) test, and blood samples were collected. Correlations between biomarker levels and WISC-IV test scores were analyzed. The ID group had an IQ score below 75, and the values of four domains (IQ, IOP, IMO, and IVP) were lower compared to the control group. Serum levels of FKN, NGF-β, and vitamin B12 were decreased in the ID group, while DCFH and nitrite levels were increased. Positive correlations were found between FKN and the QIT and IOP domains, NGF and the QIT and IMO domains, and vitamin B12 and the ICV domain. TNF-α showed a negative correlation with the ICV domain. Our study identified FKN, NGF-β, and vitamin B12 as potential biomarkers specific to ID, which could aid in the diagnosis and treatment of ID. TNF-α and oxidative stress biomarkers suggest that ID has a complex etiology, and further research is needed to better understand this condition and develop effective treatments. Future studies could explore the potential implications of these biomarkers and develop targeted interventions based on their findings.

Emotional and social functioning after stroke in childhood: a systematic review

PURPOSE

To provide an overview of the effects of pediatric stroke on emotional and social functioning in childhood.

METHODS

A literature review was completed in accordance with the Preferred Reporting Items for Systematic Reviews. A systematic search of studies on internalizing problems and social functioning after pediatric stroke in PsycInfo, PsycArticles, and PubMed databases was conducted from inception to November 2021. A total of 583 studies were identified, and 32 met the inclusion criteria.

RESULTS

The review suggests that children after stroke are at risk of developing internalizing problems and a wide range of social difficulties. Internalizing problems are often associated with environmental factors such as family functioning and parents' mental health. In addition, a higher risk of developing psychosocial problems is associated with lower cognitive functioning and severe neurological impairment.

CONCLUSIONS

The assessment of psychological well-being and social functioning after pediatric stroke is helpful to provide adequate support to children and their families. Future studies are needed to better investigate these domains and to develop adequate methodologies for specific interventions.Implication for rehabilitationThis paper reviews research concerning emotional and social functioning following pediatric stroke in order to provide helpful information to clinicians and families and to improve rehabilitation pathways.Emotional and social functioning should be addressed during post-stroke evaluation and follow-up, even when physical and cognitive recovery is progressing well.Care in pediatric stroke should include volitional treatment and address emotional and social issues.

Effectiveness of unified protocol for trans diagnostic treatment in children with anxiety disorders: A randomized control trial

BACKGROUND

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children (UP-C) is a theory-derived approach that can target the common underlying processes, such as the cognitive, emotional, and behavioral processes in emotional disorders in children aged 8-12 years. This study aimed to investigate UP-C's efficacy in treating children's anxiety disorders compared to cognitive behavior therapy (CBT).

MATERIALS AND METHODS

In this randomized control trial (RCT), with pre-test, post-test, and follow-up, 34 participants aged 8-12 with anxiety disorders were selected through the restricted randomization method and allocated to intervention (UP-C) or control (CBT) groups by random allocation rule. UP-C group consisted of 15 weekly individual sessions, and CBT included 16 weekly individual sessions. The Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA) and The Screen for Child Anxiety Related Disorders (SCARED-71) were completed in the pre-test, post-test, and three-month follow-up stages. The data of participants were analyzed using the repeated measure analysis of variance. A P- value under. 05 was regarded as significant.

RESULTS

Based on the repeated measures ANOVA, UP-C, and CBT significantly reduced anxiety symptoms (P = .002) and emotional suppression (P = .032). Moreover, UP-C and CBT significantly increased emotion regulation (P = .000) and cognitive reappraisal (P = .000).

CONCLUSION

The individual UP-C can be effective as anxiety-oriented CBT in treating anxiety disorders. Also, in the three months follow-up, the UP-C's effects were more stable and progressive than the CBT.

Review: Recommendations for male-friendly counselling with adolescent males: A qualitative systematic literature review

BACKGROUND

There are growing calls to tailor counselling practices for adolescent males, a population reluctant to engage in psychological treatment despite concerning rates of mental illness. The objective of this systematic review (PROSPERO: CRD4202125547) was to collate and synthesise recommendations for individual counselling with adolescent males (12-18 years).

METHOD

The databases Psychology and Behavioural Science Collection, PsycArticles, PsycINFO, Academic Search Complete, EBSCO eBook Collection, Wiley Science Collection, Taylor and Francis Collection and ProQuest One Academic were searched for articles published between 1995 and November 2021. The quality of evidence was assessed using the JBI critical appraisal checklists, and thematic analysis was employed to synthesise findings across the literature.

RESULTS

A total of 1625 texts were identified, of which 16 met the inclusion criteria. Generated themes included (a) therapist knowledge of masculinity, gender socialisation, and male-relational styles; (b) necessity of therapists to address masculinity in the therapeutic space; and (c) customising engagement and treatment practices to appeal to adolescent males.

CONCLUSIONS

The themes highlighted the unique developmental, and sociocultural considerations practitioners should be aware of when working with young men. Through a multicultural counselling competency framework, masculinity and adolescent male identity are expressions of diverse sociocultural identities that psychological assessment and intervention should ideally be tailored to suit. The findings of the review suggest that empirical research focusing on the experiences of adolescent males receiving psychological treatment is sparse. Further research is needed to inform the development of practicable, gender-sensitive adaptions to counselling practice for young men.

School-Based Mental Health Service Utilization Through the COVID-19 Pandemic and Beyond

BACKGROUND

We examined trends in mental health service utilization before, during, and in the immediate return to in-person learning throughout the COVID-19 pandemic.

METHODS

Retrospective chart review was assessed for changes in odds of any visit being a mental health encounter from five school-based health centers from the 2018-2019 to the 2021-2022 school years. Data are limited to the in-person school year from mid-August to early June.

RESULTS

Data were assessed from 1239 students seen through 2256 visits over the 4 school years (Mage  = 12.93). The odds of any visit being related to a mental health encounter increased each school year, with the 2020 to 2021 and 2021 to 2022 school years having significant increases in odds (both compared to the first and to the antecedent school year). In addition, during the 2019 to 2020 and 2020 to 2021 school years, the odds of a repeated mental health encounter significantly increased from year to year.

CONCLUSIONS

Findings indicate a steadily increasing number of mental health service utilization needs among adolescent students that was significantly exponentiated throughout the COVID-19 pandemic.

Psychosocial interventions for teenagers with adolescent idiopathic scoliosis: A systematic literature review

OBJECTIVES

Psychosocial interventions can improve teenagers' self-esteem, mental health and bracing compliance. There is a need to compile available evidence of psychosocial care in adolescent idiopathic scoliosis. This systematic review aimed to identify and evaluate the effects of existing interventional studies of psychosocial care for the adolescent idiopathic scoliosis population.

METHODS

A comprehensive search of relevant literature published from the inception to March 2023 was conducted using nine databases. A google scholar search was performed on 1 July 2023, to update the searching results. Two reviewers independently assessed the methodological quality and extracted details of the included studies. Given the heterogeneity of the selected articles, the findings were synthesized narratively without conducting a meta-analysis.

RESULTS

Four randomized controlled trials reported in six articles involving 385 teenagers were included. The interventions appeared acceptable with high recruitment rates and low dropout rates reported. Psychosocial interventions had shown significant positive effects on postoperative pain, engagement in daily and social activities as well as brace use, coping abilities and anxiety.

CONCLUSION

Psychosocial interventions are generally feasible and acceptable among the adolescent idiopathic scoliosis population and have produced positive effects on a variety of physical and psychosocial outcomes. Study findings need to be interpreted with caution due to the limited number of available articles and the methodological concerns of the reviewed articles.

PRACTICAL IMPLICATIONS

Well-designed clinical trials are warranted in people from cultural backgrounds to develop and implement effective psychosocial interventions for teenagers with adolescent idiopathic scoliosis, not only for those at the post-surgery stage but also for those receiving conservative treatment.

The role of threat anticipation in the development of psychopathology in adolescence: findings from the SIGMA Study

Childhood adversity is associated with psychopathology. First evidence in adults suggests that threat anticipation, i.e., an enhanced anticipation of unpleasant events creating an enduring sense of threat, may be a putative mechanism linking childhood adversity to psychopathology. This study aimed to test the indirect effect of childhood adversity on psychopathology via threat anticipation in a large community sample of adolescents. We measured childhood trauma and bullying victimization (as indicators of childhood adversity), threat anticipation, general psychopathology and prodromal psychotic symptoms in adolescents aged 12-16 years (full sample size N = 1682; minimum sample size in the complete case sample N = 449) in wave I of the SIGMA study. We found strong evidence that childhood adversity (e.g. childhood trauma, adj. β (aβ) = 0.54, p < .001) and threat anticipation (e.g. aβ = 0.36, p < .001) were associated with general psychopathology and prodromal psychotic symptoms. Moreover, there was evidence that the association between childhood adversity, general psychopathology and prodromal psychotic symptoms is mediated via pathways through threat anticipation (e.g. childhood trauma, aβindirect effect = 0.13, p < .001). Threat anticipation may be a potential mechanism linking childhood adversity and psychopathology in adolescents.

Psychological disorders and suicide attempts in youths during the pre-COVID and post-COVID era in a Taiwan pediatric emergency department

Background

The COVID-19 pandemic has had a significant impact on pediatric patients, increasing their vulnerability to psychological fragility. The aim of this study was to investigate the epidemiology and clinical spectrum of pediatric psychological fragility and suicide attempts in the emergency department (ED) before and after the onset of the COVID-19 outbreak.

Methods

A total of 340 pediatric patients admitted to the ED for psychological fragility between 2019 and 2022 were retrospectively collated and categorized according to three periods: pre pandemic, pandemic, and post pandemic. Epidemiological and clinical information were analyzed and compared among the three groups. Moreover, patients with suicidal ideation or suicidal attempts and types of substance use disorders in children with suicidal attempts sent to the ED were analyzed.

Results

The proportion of psychological fragility increased during the pandemic period (0.4%) and the post-pandemic period (0.8%) compared to that in the pre-pandemic period (0.28%). Suicide ideation was the highest before the pandemic period (0.04%), while suicidal attempts were the highest in the post pandemic period (0.42%). Significantly elevated trends in suicide attempts involving overdose and injury were observed among the three groups (p < 0.05). Intensive care unit (ICU) admission rates increased significantly after the COVID-19 outbreak (p < 0.05), and major depressive disorder was the most common psychological fragility in the ED in all three groups.

Conclusion

An increase in the proportion of pediatric psychological fragility in the ED was noted in the post pandemic period than before or during the pandemic. With higher rates of ICU admissions and an increase in suicide attempts among children and adolescents during the pandemic compared to before or after the pandemic, it is of utmost importance to provide mental health support to this vulnerable population in order to prevent suicide attempts in the event of a new global outbreak of infectious diseases.

Effectiveness of Virtual Reality in Anxiety and Pain Management in Children and Adolescents Receiving Cancer Treatment: A Systematic Review and Meta-analysis of Randomized Controlled Trials

TRIALS

The study aimed to investigate the effect of virtual reality interventions on relieving pain and anxiety in children and adolescents receiving cancer treatment. A search that involved Cochrane Library (comprising Cochrane Central Register of Controlled Trials (CENTRAL)), PubMed, ProQuest, MEDLINE, Web of Sciences, Science Direct, and Scopus electronic databases covering the records from January 1, 2000 up to May, 2023 was conducted to determine randomized controlled trials that could be included in our study. The results of the search were limited to "anxiety and pain, adolescents, children, virtual reality, cancer." Of the 160 articles that were reached during the search, seven were found eligible based on inclusion criteria. Hedges' g effect size was calculated for each article. Random effects model was used to test effect sizes and moderator variables. The registration number of this meta-analysis on PROSPERO is CRD42022304737. The outcomes were pain and anxiety. Compared with standard care, virtual reality had a medium and significant effect on anxiety (g = 0.60, 95% CI: [- 1.05 - 0.15]) and pain (g = - 0.667, 95% CI: [- 1.08- -0.24]). In addition, age has been identified as an important moderator in the use of virtual reality in pain management. This meta-analysis shows that virtual reality applications are effective interventions for reducing pain and anxiety in the field of pediatric oncology. However, it is necessary to carry out randomized controlled trials that have large samples for evidence-based virtual reality applications in pediatric oncology.

Psychological factors and pain medication use in adolescents with chronic pain

OBJECTIVE

The purpose of this study was to examine (1) the associations of anxiety, depressive symptoms, and pain catastrophizing with pain medication use in adolescents with chronic pain and (2) the extent to which these associations differed as a function of adolescents' sex.

METHODS

Cross-sectional data from 320 adolescents 12-18 years of age with chronic pain were drawn from an epidemiological study on pediatric chronic pain conducted in Reus (Catalonia, Spain). Participants were asked to provide sociodemographic information and respond to measures assessing pain (location, frequency, intensity, and interference), pain medication use, anxiety, depressive symptoms, and pain catastrophizing. Point biserial correlations were conducted to examine univariate associations between the psychological variables and pain medication use. Hierarchical logistic regression analysis was used to examine these associations while controlling for demographic characteristics, pain intensity, and pain interference.

RESULTS

Anxiety, depressive symptoms, and pain catastrophizing were significantly associated with pain medication use in univariate analyses. Regression analysis identified pain catastrophizing as a unique independent predictor of pain medication use after controlling for the effect of demographic variables (sex and age), pain intensity, and pain interference (odds ratio = 1.1, P < .05). No moderating effect of adolescents' sex on the associations between psychological factors and pain medication use was found.

CONCLUSIONS

Adolescents with chronic pain with higher levels of pain catastrophizing use pain medications more often. Research to examine the impact of interventions targeting pain catastrophizing on pain medication use among adolescents with chronic pain would be an important next step.

Developmental Trajectory of Body Weight in Youths at Risk for Major Mood Disorders

Importance

Mood disorders are associated with increased body weight, especially in females, but it remains unknown when the weight increase starts.

Objectives

To examine sex-specific weight trajectories associated with familial mood disorder risk and determine the age at which youth at familial risk for mood disorders begin to diverge in weight from controls.

Design, Setting, and Participants

This community-based, single-center, acceleration cohort study of youth at familial risk for mood disorders and controls with yearly follow-ups (mean [SD], 5 [2.1] years) from January 1, 2014, to December 31, 2022, assessed 394 unaffected female and male offspring (aged 3 to 20 years) of parents with or without a mood disorder. Parents with mood (depressive or bipolar) disorders were recruited through adult mental health services. Parents of control participants were matched on age and socioeconomic factors and recruited through acquaintance referrals or schools.

Exposures

The youth in the familial mood risk group had at least 1 parent with a major mood disorder, whereas control youth did not have a parent with a mood disorder.

Main Outcomes and Measures

Body mass indexes (BMIs) were calculated as weight in kilograms divided by height in meters squared from measured weight and height at annual assessments and then converted to age- and sex-adjusted z scores (zBMIs). Repeated-measure regressions examined the association between zBMI and age in youth at familial risk of mood disorders and controls while accounting for sex. Sensitivity analyses accounted for socioeconomic status, prematurity, and birth weight.

Results

Of 394 participants (mean [SD] age, 11.5 [3.6] years; 203 [51.5%] female), youths at familial risk for mood disorders showed overall no difference in body weight (β = 0.12; 95% CI, 0.01-0.24) from controls. A sex-specific difference was detected, with females at familial risk showing a rapid peripubertal increase in body weight, leading to significantly increased zBMIs at 12 years and older compared with controls (β = 0.57; 95% CI, 0.31-0.82) independent of socioeconomic status, prematurity, or birth weight. Males did not differ from controls at any age.

Conclusions and Relevance

In this cohort study, females with a family history of mood disorders were prone to weight gain starting around puberty and predating mood disorder onset. Early interventions aiming to prevent adverse mental and physical outcomes in this vulnerable group need to start in childhood.
