Our specific aim is to conduct a pilot randomized controlled trial (n = 40) with depressed primary care patients who will receive either antidepressant treatment as usual (aTAU) + sTVi vs aTAU + attention control videos. Assessments will occur at baseline, 4 (post-treatment) and 12 weeks (follow-up). We will examine feasibility and acceptability of sTVi (e.g., uptake and completion of sTVi, engagement with videos, and understanding of key ACT principles), the attention control videos, and this research design. We will examine treatment differences (within relevant confidence intervals) on outcomes (e.g., depression severity). We will examine change in potential mechanisms, i.e., ACT-consistent coping strategies derived from key ACT principles.
