Deficits in Emotional Clarity and Vulnerability to Peer Victimization and Internalizing Symptoms Among Early Adolescents

Neuroanatomical landscapes: Delineating the cortical signatures of pediatric major depressive disorder and bipolar disorder

Pediatric mood disorders, including Major Depressive Disorder (MDD) and Bipolar Disorder (BD), exhibit overlapping symptomatology and complex neurodevelopmental trajectories, necessitating a comprehensive investigation of their neuroanatomical underpinnings. This study aimed to characterize structural brain differences in children with MDD and euthymic BD using high-resolution structural magnetic resonance imaging (MRI). A total of 51 children (aged 10-14 years) were categorized into MDD, euthymic BD, and typically developing (TD) controls. Utilizing advanced surface-based morphometry, we examined four cortical features: fractal dimension, gyrification, sulcal depth, and cortical thickness, to delineate disorder-specific and shared neuroanatomical alterations. Additionally, we explored the interaction between white matter volumetrics and these surface-based metrics to assess its modulatory role in structural brain differences. Our results revealed significant cortical alterations, with distinct and overlapping patterns in both MDD and BD. The findings demonstrated disruptions in cortical complexity, folding patterns, and sulcal morphology, particularly in regions implicated in emotion regulation and cognitive processing. These structural variations provide critical insights into the neurodevelopmental alterations associated with pediatric mood disorders. By integrating multiple morphometric parameters, this study offers a comprehensive framework for understanding the neuroanatomical changes in MDD and BD, contributing to more precise diagnostic biomarkers. The results underscore the importance of incorporating surface-based morphometry and white matter interactions in future research to refine early diagnosis and targeted interventions for mood disorders in children.

Prospective Relations between Life Stress, Emotional Clarity, and Suicidal Ideation in an Adolescent Clinical Sample

OBJECTIVE

Although life stress has been linked to adolescent suicidal ideation, most past research has been cross-sectional, and potential processes characterizing this relation remain unclear. One possibility may be a lack of emotional clarity. Informed by stress generation, the current study examined prospective relations between episodic life stress, lack of emotional clarity, and suicidal ideation in an adolescent clinical sample.

METHODS

The sample consisted of 180 youths (Mage = 14.89; SD = 1.35; 71.7% female; 78.9% White; 43.0% sexual minority) recruited from a psychiatric inpatient facility. Suicidal ideation severity was assessed at baseline and 18-month follow-up. Lack of emotional clarity and life stress were assessed at baseline, as well as 6-, and 12-month follow-ups. Two random-intercepts cross-lagged panel models were created to estimate within-person relations for variables of interest.

RESULTS

At the within-person level, lack of emotional clarity at baseline predicted greater 6-month impact of interpersonal dependent stressors (b = 0.29, p = .012, 95% CI [0.07, 0.52]), which subsequently predicted a greater 12-month lack of emotional clarity (b = 0.41, p = .005, 95% CI [0.12, 0.70]). Next, a 12-month lack of emotional clarity but not interpersonal dependent stress, predicted greater 18-month suicidal ideation (b = 0.81, p = .006, 95% CI [0.23, 1.30]; R2 = .24, p < .001). No significant relations were found for the lack of emotional clarity and independent stress.

CONCLUSIONS

Results support the stress generation hypothesis and suggest that future research should be conducted evaluating whether bolstering youth's understanding of their emotional experiences may reduce subsequent suicidal ideation.

Psychophysiological Factors Moderate Amygdala-Prefrontal Connectivity Linked to Perceived Peer Victimization and Depressive Symptoms in Preadolescent Migrant Children

Background: As a sense of an intense stressor, perceived peer victimization can cause adverse effects on mental health, like depressive symptoms. Yet, little is known about the neurobiological mechanisms underlying how perceived peer victimization causes and maintains depressive symptoms in preadolescence. Methods: Here we investigate the effects of peer victimization on amygdala subregional functional connectivity in 101 preadolescent migrant children, and their relations to depressive symptoms and potential protective factors of self-esteem and daily cortisol. Further control analyses were conducted to verify whether there are any specific effects in migrant children compared to 54 age-matched preadolescent children from nonmigrant background. Results: Children with higher perceived peer victimization exhibited greater intrinsic functional connectivity of the amygdala with the middle frontal gyrus extending into the superior frontal gyrus. Perceived peer victimization could account for an indirect association between amygdala hyperconnectivity and depressive symptoms. Moderated mediation analyses revealed that basolateral amygdala connectivity with the superior frontal gyrus acted as a neural marker linking peer victimization and greater risk for depressive symptoms only in preadolescent children with low self-esteem or low daily cortisol. Conclusions: These findings suggest that considering neurobiological vulnerability and psychophysiological factors may gain a nuanced understanding of the adverse effects of perceived peer victimization on depressive symptoms, a risk for internalizing pathology. This study could inform personalized intervention strategies to prevent or ameliorate depressive symptoms in this disadvantaged population.

Impact of Bullying Victimization on Chinese College Students' Suicidal Tendency: The Moderating Effect of Teachers' Emotional Support and Family Support

Objective

To explore the influence of bully victims on the suicidal tendencies of college students, and the moderating role of teacher emotional support and family support in the relationship between bully victims and college students' suicidal tendencies, in order to provide a reference for the effective intervention of college students' suicide behavior.

Methods

Based on a survey of 15,560 college students. Multiple stepwise regression and Interaction analysis explore the impact of the bully victimization on college students' suicidal tendencies and the moderating role of family support and teacher emotional support in the relationship between the bully victim and college students' suicidal tendencies.

Results

This study found that the Suicidal Tendencies score of college students was 19.79 points, indicating that some college students have a risk of suicidal tendencies; secondly, verbal bullying (β = 0.084, P <0.001), physical bullying (β = 0.222, P <0.001) and social relationship bullying (β = 0.122, P <0.001) have a positive and significant impact on the suicidal tendencies of college students; in addition, family support and teacher emotional support have a significant regulatory effect on the bully victim and college students Suicidal Tendencies and family support. The regulating effect was significantly higher than that of teacher emotional support.

Conclusion

Chinese college students have the risk of suicidal tendencies; peer bullying victimization is an important reason for affecting college students' suicidal tendencies, teacher emotional support is a protective factor for bully victims to affect college students' suicidal tendencies, and family support has a significant moderating effect on the bully victim and college students' suicidal tendencies. Therefore, it is necessary to actively adopt home-school linkage and home-school communication to reduce campus violence and increase the psychological resilience of college students.

Maternal depressive symptoms and children's academic performance: sex differences in the mediating role of school experiences

BACKGROUND

Maternal depressive symptoms (MDSs) are negatively associated with children's academic performance, with stronger effects sometimes reported in boys. However, few studies have tested the mechanisms of this association. We examined the mediating role of school engagement and peer victimization in this association and tested for sex differences.

METHODS

Participants were 1173 families from a population-based longitudinal Canadian study. MDSs were self-reported annually using the Centre for Epidemiologic Studies Depression Scale (child's age: 5 months to 5 years). Data on mediators (peer victimization, cognitive, behavioral, and emotional school engagement) were reported annually from ages 6-10 by multiple informants including children, parents, and teachers using items from validated scales. Mathematics, reading, and writing exam scores at age 12 were obtained from standardized exams administered by Québec's Ministry of Education and Teaching. Structural equation modeling was used to test mediation by school experiences in boys and girls.

RESULTS

Exposure to MDSs was negatively associated with mathematics, reading, and writing scores in girls and with mathematics only in boys. Cognitive and behavioral engagement significantly mediated the association between MDSs and mathematics, reading, and writing scores in girls. There were no significant mediators for boys.

CONCLUSIONS

Prevention and intervention strategies aiming to improve school engagement might be beneficial for daughters of mothers experiencing depressive symptoms. Further research is needed to replicate these findings and to identify the mechanisms explaining this association in boys.

Social emotional ability development (SEAD): An integrated model of practical emotion-based competencies

Social emotional abilities (i.e., specific skills), defined as the set of cognitive abilities, emotion-based knowledge, and behavioral competencies (i.e., skill levels) that facilitate adaptively employing prosocial processes and behaviors (i.e., "actions"), such as emotional regulation and sympathetic and empathetic response behaviors, is contemporarily modeled and measured as emotional intelligence. This conceptualization can be problematic, however, as the two concepts are not the same and traditional methods of measuring emotional intelligence can have limited practical utility. The social emotional ability development (SEAD) theoretical model introduced in this treatise represents a pragmatic and simplified approach to the development of social emotional ability and competency as abstracted from constructs of emotional intelligence, social intelligence, and sociocultural learning theory. Further, the SEAD model reaches beyond the individual as the unit of analysis to explore, conceptualize, differentiate, investigate, and define the hierarchal, bi-directional, and contextual nature of the dimensions of social emotional ability within close relationships. Implications for how the SEAD model can be used by researchers, practitioners, educators, individuals, families, and couples across a broad spectrum of domains and interventions are discussed.

Relational Victimization and Internalizing Problems: Moderation of Popularity and Mediation of Popularity Status Insecurity

Extensive research has consistently shown an association between relational victimization and internalizing problems among adolescents. However, limited information is available about the underlying peer status related factors that may mediate or moderate this association. Using a short-term longitudinal design with a six-month interval between the two waves, this study examined whether popularity status insecurity mediated the associations between relational victimization and internalizing problems and whether this mediational process was moderated by popularity status among 447 (250 girls) Chinese 7th and 8th graders. The findings of this study show that popularity status insecurity mediated the longitudinal associations between relational victimization and the two internalizing problems, depressive symptoms and anxiety, but only for adolescents with relatively low popularity. This study reveals the moderated mediation processes explaining the impact of relational victimization on adolescents' mental health.

Examining the association between bullying victimization and prescription drug misuse among adolescents in the United States

BACKGROUND

Although studies have examined the association between bullying victimization and adolescent substance behaviors, there is a dearth of research investigating the association between bullying victimization and prescription drug misuse. The objective of this study was to examine the cross-sectional association between bullying victimization and prescription drug misuse among adolescents.

METHODS

Data for this study came from the 2017 Youth Risk Behavior Survey. A sample of 9974 adolescents aged 14-18 years (50.1% female) were analyzed using binary logistic regression with prescription drug misuse as the outcome variable and bullying victimization as the main explanatory variable.

RESULTS

Of the 9,974 adolescents, 13.1% misused prescription drugs. One in ten adolescents were victims of both school bullying and cyberbullying, 5.1% were victims of only cyberbullying, 9% were victims of only school bullying, and 75.8% experienced neither school bullying nor cyberbullying victimization. In the binary logistic regression model, adolescents who experienced both school bullying and cyberbullying victimization had 1.66 times higher odds of misusing prescription drugs (AOR = 1.66, p < .001, 95% CI = 1.34-2.06) and adolescents who experienced only school bullying victimization had 1.30 times higher odds of misusing prescription drugs (AOR = 1.30, p < .05, 95% CI = 1.02-1.64). Being lesbian, gay, or bisexual; feeling sad or hopeless; cigarette smoking; binge drinking; cannabis use; and illicit drug use were statistically significantly associated with prescription drug misuse.

CONCLUSIONS

Understanding the association between bullying victimization and prescription drug misuse could contribute to early identification of adolescents who may misuse prescription drugs.

A technology-augmented intervention to prevent peer violence and depressive symptoms among at-risk emergency department adolescents: Protocol for a randomized control trial

BACKGROUND

Peer violence and depressive symptoms are increasingly prevalent among adolescents, and for many, use the emergency department (ED) as their primary source of healthcare. Brief in-person interventions and longitudinal text-message-based interventions are feasible, acceptable, and may be effective in reducing peer violence and depressive symptoms when delivered in the ED setting. This paper presents the study design and protocol for an in-ED brief intervention (BI) and text messaging program (Text).

METHODS

This study will be conducted in a pediatric ED which serves over 50,000 pediatric patients per year. Recruitment of study participants began in August 2018 and anticipated to continue until October 2021. The study will enroll 800 adolescents (ages13-17) presenting to the ED for any reason who self-report past-year physical peer violence and past-two week mild-to-moderate depressive symptoms. The study will use a factorial randomized trial to test both overall intervention efficacy and determine the optimal combination of intervention components. A full 2 × 2 factorial design randomizes patients at baseline to 1) BI or no BI; and 2) Text or no Text. Peer violence and depressive symptoms improvements will be measured at 2, 4, and 8 months through self-report and medical record review.

DISCUSSION

This study has important implications for the progress of the greater field of mobile health interventions, as well as for adolescent violence and depression prevention in general. This proposal has high clinical and public health significance with high potential scalability, acceptability, and impact.

Emergency department text messaging for adolescent violence and depression prevention: A pilot randomized controlled trial

This study's purpose was to evaluate feasibility and acceptability, obtain preliminary efficacy data, and evaluate predictors of improvement with iDOVE, a technology-augmented violence and depression prevention intervention for high-risk adolescents seen in the emergency department (ED). We conducted a pilot randomized controlled trial (RCT) with 116 English-speaking adolescents (ages 13-17 years), presenting to the ED for any reason, who reported past-year physical peer violence and current depressive symptoms. The cognitive-behavioral therapy- and motivational interviewing-based intervention consisted of a brief in-ED intervention session and 8 weeks of automated text-message daily mood queries and tailored responses. The control was a brief in-ED presentation and twice-weekly text messages on healthy behaviors. Follow-up was conducted at 8 and 16 weeks. Descriptive statistics, bivariate comparisons, mixed-effects longitudinal regression models, and latent class models (LCMs) were calculated. iDOVE had high acceptability and feasibility, with 86% of eligible youth consenting (n = 116), 95% completing 8-week follow-up, and 91% completing 16-week follow-up. High quantitative and qualitative satisfaction were reported by intervention and control participants. Comparing intervention to control, improved depressive symptoms (p = .07) and physical peer violence (p = .01) were observed among the more symptomatic youth in the intervention group (but no difference in symptoms between full intervention and control groups). LCMs showed that intervention responsiveness correlated with lower mood (measured through daily text messages) at Day 7 of the intervention. This RCT of a technology-augmented intervention shows high feasibility and acceptability and a promising signal of reduced violence among the highest-risk participants.

Peer Relationship Outcomes of School-Age Children Born Very Preterm

OBJECTIVES

To characterize the friendship networks, peer relationships, and bullying experiences of 12-year-old children born extremely preterm (EPT; 23-27 weeks of gestation), very preterm (VPT; 28-32 weeks of gestation), and full term (FT; 38-41 weeks of gestation), and to identify child characteristics placing children at risk of peer problems.

STUDY DESIGN

A regional cohort of 44 EPT, 60 VPT, and 109 FT born children were followed prospectively to 12 years of age. The nature of children's close friendships, peer relations, and bullying experiences were assessed using a multimethod approach, including parent, teacher, and child report.

RESULTS

Across all measures, children born EPT had more peer social difficulties than children born VPT and FT. They were more likely to report no close friendships (5%-14% EPT vs 0%-3% VPT/FT), dissatisfaction with their peer network (16% vs 1%-2%), and less time interacting face-to-face with friends (16%-23% vs 5%-8%). They were also 3 times more likely to be rated by their parents and teachers as experiencing problems relating to peers (P ≤ .001). In contrast, rates of chronic bullying (≥2 times/week) were similar for EPT and VPT children (12%-14% vs 4% FT). Emotional problems, inattention/hyperactivity, and motor deficits were associated with an increased risk of peer relationship problems, whereas higher body mass index, delayed pubertal development, vision problems, and inattention/hyperactivity problems were associated with frequent bullying.

CONCLUSIONS

With the exception of bullying, risks of peer social difficulties were greatest among children born EPT. Peer social relationships should be monitored as part of longer term developmental surveillance and support.

Peer victimization and substance use: Understanding the indirect effect of depressive symptomatology across gender

OBJECTIVE

Peer victimization in school is common, with emerging literature suggesting that it may also increase risk for substance abuse. Yet, little is known about the underlying mechanisms within this risk pathway. The objective of this study is to use a prospective 3-wave design to examine the mediating role of depressive symptomatology on the relationship between peer victimization and substance use, as well as examine if the pathway varies based on gender.

METHOD

801 youth between 6th and 12th grade completed surveys across three years, which included measures on school peer victimization, depression symptomatology and substance use. Models tested the mediational pathway between victimization, depressive symptoms, and substance use. Models were stratified by gender.

RESULTS

Controlling for grade and the effect of each variable across waves, a significant indirect effect of peer victimization on substance use through depressive symptoms was found for females, with a non-significant indirect effect for males.

CONCLUSION

Results suggest that female youth who are victimized by peers engage in substance use behaviors, at least in part, due to increases in depressive symptoms. Given its effect on depression, female victims may therefore benefit from coping skills training that targets emotion regulation and distress tolerance skills in order to combat increased risk for substance use behaviors as a coping response to their victimization. Further research is warranted to better understand the risk pathway for male youth who also experience peer victimization.

Understanding Emotion in Adolescents: A Review of Emotional Frequency, Intensity, Instability, and Clarity

Adolescence is a time of transition from childhood to adulthood during which significant changes occur across multiple domains, including emotional experience. This article reviews the relevant literature on adolescents’ experience of four specific dimensions of emotion: emotional frequency, intensity, instability, and clarity. In an effort to examine how emotional experiences change as individuals approach adulthood, we examine these dimensions across ages 10 to 19, and review how the emotional functioning of adolescents compares to that of adults. In addition, we explore whether and how gender and puberty explain age differences in emotional experience. Finally, we discuss how these findings could inform future research on both the typical trajectory of emotional experience and the development of psychopathology in adolescence.

Emotional clarity development and psychosocial outcomes during adolescence

Past research on emotional clarity (EC), the ability to identify and label one's own emotions, has illustrated an association between EC deficits and poor psychosocial outcomes during the adolescent years. Although past research has connected EC to psychosocial outcomes during adolescence in cross-sectional and longitudinal designs, no studies have traced the trajectory of EC over time to determine the developmental course of the construct during adolescence. Thus, this study investigated how EC developed over five years during adolescence and what factors were associated with the developmental trajectory of emotional clarity. Participants included a diverse sample of 640 adolescents (M age at Time 1 = 12.55 years; 53.0% female; 52.2% African American; 48.0% eligible for free school lunch). Results indicated that EC tended to decrease over adolescence, and females, on average, had a steeper decline of EC over time than males. The trajectory of EC predicted psychosocial outcomes, including depression and well-being. Results are discussed with the ultimate goal of informing novel prevention and intervention programs to promote adaptive emotional functioning during an influential time in human development.

The mediating effect of depressive symptoms on the relationship between bullying victimization and non-suicidal self-injury among adolescents: Findings from community and inpatient mental health settings in Ontario, Canada

Although bullying victimization has been linked to a number of behavioral and emotional problems among adolescents, few studies have investigate the mechanism through which bullying victimization affect non-suicidal self-injury. The objectives of this study were to examine the effect of bullying victimization on non-suicidal self-injury and the mediating effect of depressive symptoms on the relationship between bullying victimization and non-suicidal self-injury among adolescents. Data for this study came from the interRAI Child and Youth Mental Health dataset. A total of 1650 adolescents aged 12-18 years (M =14.56; SD =1.79; 54.2% males) were analyzed. Binary logistic and Poisson regression models were conducted to identify the mediating effect of depressive symptoms on the relationship between bullying victimization and non-suicidal self-injury. Of the 1650 adolescents studied, 611 representing 37% engaged in non-suicidal self-injury and 26.7% were victims of bullying. The effect of bullying victimization on non-suicidal self-injury was partially mediated by depressive symptoms after adjusting for the effect of demographic characteristics, history of childhood abuse, social support, and mental health diagnoses. The contribution of bullying victimization and depression to non-suicidal self-injury adds to the case for the development of trauma-focused interventions in reducing the risk of non-suicidal self-injury among adolescents.

Trait Emotional Intelligence Related to Bullying in Elementary School Children and to Victimization in Boys

While Healthy People 2020 calls for a reduction of bullying among high school students as a public health priority, earlier intervention supported by Occupational Therapists may be warranted. The current study investigated the prevalence of bullying behaviors within an elementary school, compared the experiences of victims with those of perpetrators, and determined when and for whom Trait Emotional Intelligence is a predictor of bullying and victimization. Elementary school children ( n = 235) in Grades 3 to 5 completed the Forms of Bullying Scale-Victim, the Forms of Bullying Scale-Perpetrator, and the Trait Emotional Intelligence Questionnaire-Child Short Form. The prevalence of bully-only perpetration was 3.0%, of victimization-only was 48.5%, and of bully-victimization was 10.4%. Trait Emotional Intelligence was negatively associated with bullying. Trait Emotional Intelligence was negatively associated with victimization in boys, but not girls. The findings are discussed within the need to provide instruction and services to students at an early age.

Peer Victimization and Depressive Symptoms Among Rural-to-Urban Migrant Children in China: The Protective Role of Resilience

Peer victimization can have a profound effect on children’s wellbeing and is a known risk factor for depression in childhood. Migrant children experience peer victimization at higher rates than non-migrant peers; however, limited research has examined psychological factors that may serve to reduce depression risk for this group. In particular, no studies have yet investigated whether resilience, including personal characteristics, and a strong social support network, may moderate the relationship between peer victimization and depressive symptoms for migrant children. This study utilized a latent interaction model to examine the effect of resilience on the relationship between peer victimization and depressive symptoms among 721 rural-to-urban migrant children in Beijing, China. Results indicated that peer victimization was positively associated with depressive symptoms. Resilience was found to be a protective factor for depressive symptoms and also mitigated the effects of peer victimization on depressive symptoms. Exploratory analyses suggest that enrollment in private migrant schools may be linked with poorer psychosocial outcomes for Chinese migrant children. Strengthening the internal resilience and social supports for all migrant children may be an effective strategy to lower their risk for depression. Implications for intervention are discussed.
