About

The goal of this project is to train community mental health therapists in behavioral activation (BA) treatment for major depressive disorder and then to conduct a study examining the feasibility of evaluating the effectiveness of BA in this setting.

Full description

After finalizing a 9-session BA treatment model for major depressive disorder in the Community Mental Health Center (CMHC) setting, the final treatment manual will be used to train clinicians in BA at the CMHC through workshops and training cases.

Upon completion of training and certification of adequate implementation of BA, a total of 80 patients with MDD will be randomly assigned in a 3:1 ratio to 9 sessions of BA or treatment-as-usual (TAU) at the CMHC. Feasibility will be assessed in terms of (1) percent of eligible patients who refuse randomization, (2) percent of patients who complete 9 sessions of BA treatment, (3) percent of BA homework assignments that are completed, (4) percent of monthly assessments obtained, and (5) patient ratings of credibility and alliance in BA treatment. The ability of CMHC therapists to adequately implement BA will be assessed by rating taped sessions on BA adherence and competence scales. In addition to feasibility/acceptability of BA and TAU, this study is designed to test whether theoretically important targets of BA change over the course of BA treatment, and whether such changes are associated with changes in depressive symptoms. The target measures will be assessed at baseline, month 1, month 2, and month 3. To support the potential role of these targets as the mechanisms of change in BA, change in the target variables will be examined in relation to change in depression symptoms. The investigators will also pilot a potential moderator of treatment effects (trait reward processing, as measured at baseline using the Effort-Expenditure for Rewards Task) to include this potential moderator in a subsequent fully-powered study with the long-term goal of identifying the types of patients most responsive to BA.

80 participants in 2 patient groups

behavioral activation

Experimental group

Description:

The core principles of the BA model are: (1) the key to changing how people feel is helping them change what they do, (2) changes in life can lead to depression, and short-term coping strategies may keep people stuck over time, (3) the clues to figuring out what will be antidepressant for a particular client lie in what precedes and follows the client's important behaviors, (4) structure and scheduling of activities should follow a plan, not a mood, (5) change will be easier when starting small, (6) activities that are naturally reinforcing should be emphasized, (7) the therapist should act as a coach, (8) a problem-solving empirical approach should be emphasized with recognition that all results are useful, (9) patients should be encourages to not just talk, do! (10) possible and actual barriers to activation should be examined. Patients can also receive medications in this arm.

Treatment:

Behavioral: behavioral activation

treatment-as-usual

Other group

Description:

Patients will receive psychotherapy (and potentially medications) as part of treatment-as-usual provided in the CMHC setting.

Treatment:

Behavioral: treatment-as-usual
