Phase II is a feasibility study of the revised CBT and MM manuals. Phase II involves similar procedures as Phase I; sites assigned to COMB will implement the revised CBT and MM manuals. Participants at TAU sites will receive treatment for depression that is typical at that site. As in Phase I, psychopharmacological and psychosocial interventions will not be standardized and participants may receive any depression treatment recommended by the site clinicians while on study. Depression symptoms and treatment regimens for all participants will be documented for 24 weeks. Additionally, all Phase II participants will have 2 follow-up visits at weeks 36 and 48. Again, site staff and participants at COMB sites will participate in an exit interview. The findings from these interviews will be used to revise both CBT and MM manuals at the end of Phase II.
