A Feasibility Study of Behavioral Activation for Major Depressive Disorder in a Community Mental Health Setting. Issue 1 (January 2021) - Crits-Christoph, Paul
Abstract: Behavioral activation (BA) is a well-supported treatment approach, but little research has been conducted on the effectiveness of this treatment within publicly funded community mental health settings. We examined the feasibility of conducting a randomized trial examining the effectiveness of nine sessions of BA as a treatment for major depressive disorder (MDD) in a community mental health clinic (CMHC) setting. Following adaptation of a BA manual and training of BA therapists, 80 patients seeking treatment at a CMHC were randomized, with a 3:1 randomization rate of BA to nine sessions of treatment as usual (TAU). Feasibility assessments indicated that only one eligible patient refused randomization and, of patients who attended at least one session, the median number of sessions was six for the BA group and eight for the TAU group. Of three postbaseline monthly assessments, 71.3% (171/240) were successfully obtained. On average, patients in the BA condition completed homework assignments 83.9% of the time. Treatment fidelity ratings indicated that substantially more BA techniques were delivered in the BA group compared to the TAU group ( d = 2.11). Measures of BA mechanisms improved significantly over time and these changes were significantly associated with change in depressive symptoms. These results indicate that it is feasible to conduct a randomized study of BA for MDD in a CMHC setting. In addition, the study reconfirmed the potential importance of theory-relevant BA mechanism variables. Following these findings, further investigation into the effectiveness of BA in this setting is needed. Highlights: We tested the feasibility of evaluating behavioral activation (BA) in a community mental health clinic (CMHC). The median number of sessions was six for BA and eight for treatment as usual (TAU). Patients receiving BA completed homework assignments 83.9% of the time. Substantially more BA techniques were delivered in BA compared to TAU. BA mechanism variables improved over time.
