Abstract

Despite significant public health concerns, the association between problematic peer relations (e.g., bullying) and psychopathology remains unclear. Thus far research has suggested three possible models of this association: that peer relations lead, or are a risk factor for symptoms of psychopathology (interpersonal risk model); lag, or are a consequence of psychopathology (interpersonal scar model); or both lead and lag psychopathology (transactional model). We additionally propose and test the hypothesis that peer relations may be a leading or lagging indicator of psychopathology depending on the developmental period (developmental model). Measures of youth’s peer relations (as reported by a parent and teacher on the MacArthur Health and Behavior Questionnaire (HBQ)) and clinical symptoms (as indicated by a clinician on a semi-structured clinical interview (PAPA/CAPA)) were assessed at up to 6 time points between the ages of 3 and 11. We used bivariate latent change score models to identify leading/lagging longitudinal relationships between different aspects of children’s peer relations (peer victimization, peer-directed aggression, social withdrawal, and prosocial behavior) and dimensions of psychopathology (depression, anxiety, and externalizing symptoms). Results indicated that peer victimization was a significant leading indicator of depression from early childhood into early adolescence, and aggression of externalizing symptoms (specifically in late childhood/early adolescence). Findings emphasize bullying (both as a victim or perpetrator) as a substantial risk factor for depression and externalizing disorders, even beyond established risk factors such as adverse life events, socioeconomic status, and psychiatric family history.
