Social competence and social support as mediators between comorbid depressive and conduct problems and functional outcomes in middle school children

This study examined the roles of social competence and social support as potential mediators of the association between psychopathology and functional outcomes in a middle school sample (n = 521). Participants were stratified into four psychopathology risk groups (depression only, conduct problems only, comorbid depression and conduct problems, low symptoms) based on screening during early 6th grade. Functional outcomes were 6th grade point average (GPA) and parent rating of global adaptive functioning in their 7th grade student. Low levels of social competence were found to mediate the association between symptoms and both lower grades and global functioning for adolescents with depressive symptoms alone and with comorbid symptoms, but not for those with conduct problems alone. Lack of social support mediated the association between psychiatric symptoms and lower grades for adolescents with depression alone and comorbid symptoms, but not for those with conduct problems alone. These findings suggest that intervention to improve social competence and social support may enhance functional outcomes, especially for youth with depressive symptoms or comorbid depressive and conduct symptoms.
