A Pilot Study of Brief, Stepped Behavioral Activation for Primary Care Patients with Depressive Symptoms.

In a prior pilot study with primary care patients experiencing depressive symptoms, we observed positive outcomes for a behavioral activation protocol involving one visit and three calls. We aimed to pilot test a stepped version with flexible numbers of contacts. Fifteen primary care patients scoring 5-14 on the Patient Health Questionnaire-9 engaged in the three-tiered telephone-based intervention: (1) two calls (15-20 min each); (2) one 30-60 min encounter followed by two calls; and (3) one to six calls. Participants completed assessments at pre-treatment, post-treatment, and three months later. Participants improved from baseline to post-treatment and three months later for depressive symptoms, anxiety symptoms, and disability. Most participants (9 of 15) engaged in the first tier only, averaging less than one hour of contact, and reported benefits and high satisfaction. This intervention showed preliminary evidence of feasibility, acceptability, satisfaction, and benefits, warranting further pilot testing with primary care personnel.
