Interpersonal Factors, Peer Relationship Stressors, and Gender Differences in Adolescent Depression.

Girls (vs. boys) exhibit higher levels of co-rumination and affective empathy, but not excessive reassurance-seeking. The prevalence of different forms of peer relationship stressors (e.g., peer victimization) varies by gender depending on the specific type. Evidence is mixed regarding gender differences in the association between peer victimization and depression. Gender differences in the association between peer victimization and depression not only depend on peer victimization subtype but also on the country. Most studies were conducted in non-clinical samples, highlighting the need for future research to assess major depressive disorder (not just depressive symptoms). Future research should also assess interpersonal factors (e.g., co-rumination) and peer relationship stressors together.
