Evaluating the Efficacy of Behavioral Activation Among Spanish-Speaking Latinos

Although MDD is very treatable, the lack of empirically-supported treatments precludes this population's access to quality mental health care. Following the promising results of a small open-label pilot study in which we tested the efficacy of Behavioral Activation Treatment for Depression (BATD) in a sample Latinos with Spanish-speaking preference, we conducted a randomized control trial (RCT; N = 46) that compared BATD (N = 23) to supportive counseling (N = 23) across various domains, including depression, BATD proposed mechanisms (activity level and environmental reward), and non-specific psychotherapy factors.

Results indicated that relative to SC, BATD led to greater decreases in depressive symptoms over time (p = 0.04) and greater MDD remission at the end of treatment and at the one-month follow-up (p = 0.01). Activity level (p = 0.01) and environmental reward (p = 0.05) showed greater increases over time among participants who received BATD compared to SC. Further, proposed BATD mechanisms of change did not correspond over time with depressive symptomatology.
