Abstract

Early intervention may increase the likelihood that students with depressive symptoms complete degree requirements and reduce the likelihood of negative outcomes associated with depression in adults. The goal of this study was to assess the efficacy of a 1-session version of Brief Behavioral Activation Treatment for Depression-Revised (BATD-R; Lejuez, Hopko, Acierno, Daughters, & Pagoto, 2011) with university students with mild-to-moderate depressive symptoms. Participants (N = 39) were randomly assigned to either a clinical or a control group. Participants completed measures of depression, negativity bias, mindfulness, and experiential avoidance at pre-intervention, two-week follow-up, and one-month follow-up. Both ITT and study completer analyses were conducted. There was a significant main effect of session, such that depression scores decreased from Session 1 to Session 2 and increased from Session 2 to Session 3. Depression scores at Session 3 were significantly lower than scores at Session 1. No significant differences were identified for condition at any time, suggesting that factors other than the intervention were causing the changes in depression scores. Implications for theory and practice are discussed.
