Background: Major Depressive Disorder (MDD) is a disabling mood disorder, profoundly affecting a large number of adolescent’s quality of life. To date, no obvious treatment of choice for MDD in adolescents is available and progress in the treatment of depressed adolescents will have important public health implications. Attachment-Based Family Therapy (ABFT), as the only empirically supported family therapy model designed to treat adolescent depression, aims to repair interpersonal ruptures and rebuild an emotionally protective parent-child relationship.Objective: To study the effectiveness of ABFT compared with treatment as usual (TAU) delivered within child- and adolescent mental health services (CAMHS) to adolescents with MDD.Method: Sixty adolescents (86.7% girls), aged 13-18 years (M = 14.9, SD = 1.35), with MDD referred to two CAMHS were randomized to receive 16 weeks of ABFT or TAU. ABFT consisted of weekly therapy sessions (family/individual or both) according to the treatment manual. TAU was not monitored. Primary outcomes were assessed clinician-rated by blinded evaluators (Hamilton Depression Scale, HAMD)at baseline and post-treatment with the Hamilton Depression Scale (HAMD).and Sself-reported (Beck Depression Inventory-II, BDI-II) depressive symptoms were assessed at baseline and post-treatment by blinded evaluators for HAMD and at baseline, and after 4, 6, 8, 10,12, 14, and 16 weeks for BDI-II. Analyses were performed according to intent-to-treat principles.Results: At post-treatment, clinician-rated remission rates on the HAMD (5 % in ABFT and 3.33% in TAU, p =1, OR=1.54, Fisher’s exact test) and self-reported symptoms of depression on the BDI-II did not differ significantly between groups (X2[2, N = 60] =0.06 , p = 0.97). In both treatment groups participants reported significantly reduced depressive symptoms, but the majority (63.3 %) of adolescents were still in the clinical range after 16 weeks of treatment.Conclusion: ABFT was not associated with more favorable outcomes thannot superior to TAU. Remission and response rates were low in both groups, suggesting none of the treatments were effective in treating MDD in adolescents. Findings must be viewed in the context of the study’s limitations and implementation challenges. These finding scall forContinued efforts to improve treatment for MDD in outpatient clinics are warranted . Policies on implementation of evidence based treatments already available are essential. Future research may focus onshould examine moderators of and mechanisms for individual differences to treatment response, as well as the feasibility and cost-effectiveness of implementing treatment models which may require extensive training and expertise to yield clinically meaningful improvements in non-research settings.Trial Registration: Clinicaltrials.gov identifier: NCT01830088https://clinicaltrials.gov/ct2/show/NCT01830088?term=Villab%C3%B8&draw=2&rank=1 Date of registration: April 12, 2013
