Abstract
OBJECTIVE: To conduct a randomized controlled trial to evaluate the preliminary efficacy of family-based interpersonal psychotherapy (FB-IPT) for treating depression in preadolescents (aged 7-12 years) as compared to child-centered therapy (CCT), a supportive and nondirective treatment that closely approximates the standard of care for pediatric depression in community mental health. METHOD: Preadolescents with depression (N = 42) were randomly assigned FB-IPT or CCT. Pre- and posttreatment assessments included clinician-administered measures of depression, parent- and child-reported depression and anxiety symptoms, and parent-child conflict and interpersonal impairment with peers. RESULTS: Preadolescents receiving FB-IPT had higher rates of remission (66.0% versus 31%), a greater decrease in depressive symptoms from pre- to posttreatment, and lower depressive symptoms at posttreatment (R(2) = 0.35, ΔR(2) = 0.22; B = -8.15, SE = 2.61, t[37] = -3.13, p = .002, F(2) = 0.28) than did preadolescents with depression receiving CCT. Furthermore, preadolescents in the FB-IPT condition reported significant reductions in anxiety and interpersonal impairment compared with preadolescents in the CCT condition. Changes in social and peer impairment from pre- to posttreatment were associated with preadolescents' posttreatment depressive symptoms. There was a significant indirect effect for decreased social impairment accounting for the association between the FB-IPT and preadolescents' posttreatment depressive symptoms. CONCLUSION: Findings indicate FB-IPT is an effective treatment for preadolescent depression and support further investigation of interpersonal mechanisms by which FB-IPT may reduce preadolescent depression.
