Peer victimisation during adolescence and its impact on depression in early adulthood: prospective cohort study in the United Kingdom

Associations between Unsociability and Peer Problems in Chinese Children and Adolescents: A Meta-Analysis

Research has shown that unsociability, reflected as a personal choice, is not necessarily associated with socio-emotional problems in Western countries. However, the associations between unsociability and peer problems are consistently evident in Chinese culture, yet the strength and direction in these associations are mixed. The present study aimed to examine whether unsociability is associated with peer problems and explored the potential moderators among the associations. A meta-analysis was conducted using publications that measured unsociability and peer problems. A total of 21 articles involving 43 effect sizes from 12,696 Chinese children and adolescents were included. The results revealed that (1) unsociability was positively associated with peer problems (r = 0.32, p < 0.001) among children and adolescents. (2) Informants (i.e., self-reports, peer nominations, teacher ratings, and parent ratings) and living areas (i.e., urban, suburban, and rural areas) significantly moderated the associations between unsociability and peer problems. Specifically, the associations were stronger for peer-nominated unsociability, self-reported peer problems, and samples in suburban areas. These findings shed light on unsociability linked to higher levels of peer problems among Chinese children and adolescents. Still, the influences are unique to peer problems and moderated by both data sources and environmental factors.

Perceived friend support buffers against symptoms of depression in peer victimized adolescents: Evidence from a population-based cohort in South Korea

BACKGROUND

Peer victimization is associated with an increased risk for depression, but there is less evidence on how certain factors such as friend support can buffer this association. This study investigated the associations between friend support and depressive symptoms among victimized and non-victimized adolescent girls and boys from South Korea.

METHODS

Participants includes 2258 students from the Korean Children and Youth Panel Survey, a nationally representative sample of middle school students in South Korea. Self-reported perceived friend support, depressive symptoms and peer victimization were measured using validated scales during middle school year 3 (mean age= 15.7 years).

RESULTS

The association between peer victimization and depressive symptoms varied by sex (p for sex by peer victimization interaction<0.05). Peer victimization was more strongly associated with same year depressive symptoms in girls (β=0.55) than boys (β=0.24). After controlling for key confounders, including prior year mental health symptoms, higher levels of friend support were found to attenuate the association between peer victimization and depressive symptoms (p for friend support by peer victimization interaction <0.05). Peer victimization was associated with more depressive symptoms for adolescents with low and moderate friend support, but not those with high friend support.

LIMITATIONS

Peer victimization, depressive symptoms, and friend support, were self-reported and measured the same year.

CONCLUSIONS

Friend support protects victimized South Korean adolescents from the negative effect of peer victimization on depressive symptoms, hence contributes to closing the gap in depression between victimized and non-victimized adolescents.

Relationships between family functioning, parenting and peer victimization in adolescent depression: A cross-sectional study

OBJECTIVE

Major depressive disorder (MDD) in adolescence is a prevalent mental health problem with a complex etiology and a rising incidence. The aim of the study investigated functioning of family, attitudes of parents, and peer victimization in adolescents with MDD and to compare those with healthy adolescents.

METHODS

The study was designed as a multi-center, cross-sectional, case-control study. 98 adolescents diagnosed with MDD and 99 healthy controls were recruited for the study. Beck depression inventory, parental attitude research instrument (PARI) tool, family assessment device (FAD), and multidimensional peer victimization scale (MPVS) were applied to all participants. Descriptive, correlational, and bivariate group comparisons were used in analyses.

RESULTS

The average ages of adolescents with MDD and control adolescents were 14.7 (S.D.=1.5) and 15.0 (S.D.=1.6) years, respectively. Females formed 74.5% of youth with MDD (vs. 70.3% of controls). The groups were similar in terms of socio-demographic features (all p>0.05). Adolescents with MDD had significantly elevated scores in FAD subscales except problem solving, PARI rejection of homemaking, marital conflict, and authoritarian subscales, and all MPVS subscales. Adolescents with MDD also displayed significant positive correlations between all MPVS subscales and FAD subscales except FAD problem-solving.

CONCLUSION

This cross-sectional, multi-center study suggests that family dysfunction and peer victimization may be higher in youth with MDD. Although cross-sectional design precludes evaluation of causality, it may be prudent to evaluate family functions as well as peer victimization of depressed youth.

The vicious circle of social exclusion and psychopathology: a systematic review of experimental ostracism research in psychiatric disorders

Social exclusion (ostracism) is a major psychosocial factor contributing to the development and persistence of psychiatric disorders and is also related to their social stigma. However, its specific role in different disorders is not evident, and comprehensive social psychology research on ostracism has rather focused on healthy individuals and less on psychiatric patients. Here, we systematically review experimental studies investigating psychological and physiological reactions to ostracism in different responses of psychiatric disorders. Moreover, we propose a theoretical model of the interplay between psychiatric symptoms and ostracism. A systematic MEDLINE and PsycINFO search was conducted including 52 relevant studies in various disorders (some of which evaluated more than one disorder): borderline personality disorder (21 studies); major depressive disorder (11 studies); anxiety (7 studies); autism spectrum disorder (6 studies); schizophrenia (6 studies); substance use disorders (4 studies); and eating disorders (2 studies). Psychological and physiological effects of ostracism were assessed with various experimental paradigms: e.g., virtual real-time interactions (Cyberball), social feedback and imagined scenarios. We critically review the main results of these studies and propose the overall concept of a vicious cycle where psychiatric symptoms increase the chance of being ostracized, and ostracism consolidates or even aggravates psychopathology. However, the specificity and stability of reactions to ostracism, their neurobiological underpinnings, determinants, and moderators (e.g., attachment style, childhood trauma, and rejection sensitivity) remain elusive.
