The research will determine (i) if a course of problem solving therapy (PST) and Brief Behavioral Therapy for Insomnia (BBTI), with boosters, reduces incidence of major depressive episodes over 12 months relative to usual care, and (ii) the extent to which behavioral therapies achieve these effects through enhancement of protective factors, such as greater self-efficacy, better targeting of services to address needs, and greater control over home environments.
