Can Cognitive-Behavioral Therapy Be Optimized With Parent Psychoeducation? A Randomized Effectiveness Trial Of Adolescents With Major Depression In Puerto Rico

This is a longitudinal randomized control trial on the impact of adding a parent psychoeducation intervention (TEPSI) as part of cognitive-behavioral therapy (CBT) for adolescents with Major Depressive Disorder (MDD) in a Puerto Rican sample. We tested the efficacy of adding 8 group sessions of TEPSI to 12 sessions of individual CBT on reducing depressive symptoms, MDD diagnosis, and improving family functioning. Participants (n = 121) were randomized to individual CBT with or without TEPSI. No main group effects were found for most patient domains including depression symptoms, as well as presence of adolescent's MDD diagnosis at posttreatment. Results did show a main effect of CBT over time for depression symptoms, suicide ideation, family criticism, and the presence of MDD diagnosis decreasing from pre- to postintervention. A year post treatment, almost 70% of adolescents in both conditions (CBT and CBT + TEPSI) remained in remission. A main effect was obtained for treatment in the adolescent's perception of familism and family emotional involvement. The primary hypothesis that family psychoeducation would optimize CBT for depression in adolescents was not supported. Both conditions yielded similar clinical end points. The culturally adapted CBT was found effective with Latino/a adolescents showing clinically significant improvements from pretreatment to posttreatment and remained stable at a 1-year follow-up. Regarding family outcomes, adolescents in CBT + TEPSI remained stable from pretreatment to posttreatment on family emotional involvement, while adolescents in CBT-alone showed an increase. The implication of these findings is discussed.
