Dialectical behavior therapy for adolescents with bipolar disorder: results from a pilot randomized trial.

OBJECTIVE: The purpose of this study was to conduct a pilot randomized trial of dialectical behavior therapy (DBT) versus psychosocial treatment as usual (TAU) for adolescents diagnosed with bipolar disorder (BP).

METHODS: We recruited participants 12-18 years of age with a primary BP diagnosis (I, II, or operationalized not otherwise specified [NOS] criteria) from a pediatric specialty clinic. Eligible patients were assigned using a 2:1 randomization structure to either DBT (n=14) or psychosocial TAU (n=6). All patients received medication management from a study-affiliated psychiatrist. DBT included 36 sessions (18 individual, 18 family skills training) over 1 year. TAU was an eclectic psychotherapy approach consisting of psychoeducational, supportive, and cognitive behavioral techniques. An independent evaluator, blind to treatment condition, assessed outcomes including affective symptoms, suicidal ideation and behavior, nonsuicidal self-injurious behavior, and emotional dysregulation, quarterly over 1 year.

RESULTS: Adolescents receiving DBT attended significantly more therapy sessions over 1 year than did adolescents receiving TAU, possibly reflecting greater engagement and retention; both treatments were rated as highly acceptable by adolescents and parents. As compared with adolescents receiving TAU, adolescents receiving DBT demonstrated significantly less severe depressive symptoms over follow-up, and were nearly three times more likely to demonstrate improvement in suicidal ideation. Models indicate a large effect size, for more weeks being euthymic, over follow-up among adolescents receiving DBT. Although there were no between-group differences in manic symptoms or emotional dysregulation with treatment, adolescents receiving DBT, but not those receiving TAU, evidenced improvement from pre- to posttreatment in both manic symptoms and emotional dysregulation.

CONCLUSIONS: DBT may offer promise as an adjunct to pharmacotherapy in the treatment of depressive symptoms and suicidal ideation for adolescents with BP. The DBT focus on commitment to treatment may be important for the treatment of early-onset BP. Larger controlled trials are needed to establish the efficacy of this approach, examine impact on suicidal behavior, and demonstrate cost effectiveness.
