PURPOSE The purpose of this study was to explore whether adolescent-perceived family functioning moderates the depression treatment effects on suicidal ideations.
METHODS This is a nonpreregistered exploratory secondary analysis of the TADS RCT, which included four treatment groups: fluoxetine, CBT, their combination, and placebo. A random coefficients regression model with posteriori CONTRAST statements was conducted to examine the effects of depression treatment on adolescents' suicidal ideations over time (N = 439). Baron and Kenny's (1986) and Kraemer et al.'s (2002) approach was followed to explore family functioning as a potential moderator of the treatment effects on suicidal ideations over time.
RESULTS Adolescents in the four treatment groups did not differ significantly in their suicidal ideations at initial status; however, those in the combination group had faster reduction in suicidality. Family functioning moderated the relationship between depression treatment and adolescents' suicidal ideations. In particular, the results revealed that for adolescents who reported positive family functioning (n = 249), treatment had a significant impact on their suicidal ideations over time. However, for adolescents who reported negative family functioning (n = 190), type of treatment did not have a differential effect on improvement in severity of suicidal ideation over time.
CONCLUSION Findings provided evidence that the process by which depression treatment impacts adolescents' suicidality is contingent upon their family environment. Family-centered approaches to adolescent depression treatment are recommended.
