The Relationship of Rejection Sensitivity to Depressive Symptoms in Adolescence: The Indirect Effect of Perceived Social Acceptance by Peers

Rejection sensitivity (RS), the tendency to expect, perceive and overreact to rejection from others, has been linked to children's and adolescents' increased vulnerability to depressive symptoms, negatively affecting their perceptions of the quality of their relationship with their peers. The aim of this study is to examine (a) the indirect effect of perceived peer social acceptance in the relationship between RS and depressive symptoms in a sample of Greek adolescents, (b) the differential effect of the different components of rejection sensitivity (angry and anxious RS) on the model, and (c) possible gender differences. The sample of the study consists of 295 adolescents (139 boys, 156 girls, Mage = 14.20, SD = 1.60) residing in the greater Heraklion Prefecture area. Data collection was carried out using self-report questionnaires that measured demographic characteristics, self-perceptions about their peer relationships (self-perception profile for adolescents/SPPA), susceptibility to rejection (children's rejection sensitivity questionnaire/CRSQ), and depressive symptoms (children's depression inventory/CDI). Results showed that (a) RS was positively related to depressive symptoms and negatively related to adolescents' perceptions of their relationships, (b) relationship perceptions were negatively related to depressive symptoms, and gender differences were also found, (c) perceived social acceptance by peers was found to have an indirect effect in the relationship between RS and depressive symptoms, with girls showing a greater effect, and (d) differences were observed in the mediating model between the components of RS, with the mediating effect of perceptions being higher in the model with anxious RS, which appears to confirm previous theoretical postulations. The results of this study highlight the importance of adolescents' perceptions of their peer relationships in the occurrence of depressive symptoms during this developmental period, especially in youths with anxious rejection sensitivity.

Peer victimization and adolescent problematic social media use: The mediating role of psychological insecurity and the moderating role of family support

Peer victimization is a serious risk factor for the development of problematic social media use (PSMU) among adolescents. However, little is known about the mediating and moderating mechanisms underlying this association. The current study tested whether psychological insecurity mediated the relation between peer victimization and PSMU, and whether this mediating process was moderated by family support among adolescents. A large sample of 1506 Chinese adolescents (M_age = 13.74 years, SD = 0.98) completed self-report measures regarding peer victimization, psychological insecurity, family support, and PSMU. After controlling for age, gender, and family economic status, results indicated that increased peer victimization was associated with higher psychological insecurity, which in turn predicted a greater incidence of PSMU. Moreover, family support moderated the first part of the mediation process, such that the relation between peer victimization and psychological insecurity was exacerbated for adolescents with high family support. This study advanced the current understanding of the mediating and moderating mechanisms associating peer victimization with PSMU among adolescents.
