The primary outcome was depression severity, measured by BDI scores at 2-week intervals from intervention start at 0 weeks until intervention end at 8 weeks. Secondary outcomes were self-efficacy and self-esteem, measured respectively by scores on the General Self-Efficacy Scale (GSES) and the Rosenberg Self-Esteem Scale (RSES) at 0 weeks and at 8 weeks. Blinded assessors analyzed outcome data from both intervention groups, testing whether change in outcome measures would be statistically comparable between the two groups.
