Depressive symptoms are common during adolescence. Failure at school often relates to low self-efficacy that, in turn, is associated with depressive symptoms. Several studies have supported the role of friends in counteracting depression in adolescence. The present study tested a mediation model in which the indirect effect between school achievement and depressive symptoms, mediated by perceived self-efficacy, was moderated by peer relationships at school. Self-report questionnaires were administered to 1004 adolescents aged 14 to 18 years (M = 15.5; SD = 1.2).

Purpose: The purpose of this study was to extend our knowledge of the relationship between quantitative and qualitative job insecurity and performance. On the basis of stress theories, we hypothesised that qualitative job insecurity (QLJI) would mediate the negative effect of quantitative job insecurity (QTJI) on two different indicators of performance: task performance (TP) and counterproductive work behaviours (CPWBs). In addition, the authors hypothesised that the effect of QTJI on QLJI would be moderated by the economic sector (public vs private) in which employees worked.
