The purpose of this project was to develop a short-term, theory-based intervention for patients with self-reported limited self-efficacy to perform coping behaviors. Cancer patients with low coping self-efficacy were randomly assigned to a treatment (N = 66) or control condition (N = 68). The treatment, Mastery Enhancement Therapy, was based on self-regulation and self-efficacy theories. Measures of coping self-efficacy, functional status, depression, quality of life, and adjustment were administered at baseline, after session two, after the final (fourth) session, and at 3 months post-treatment. Control participants completed the measures at about the same time intervals. Treatment participants reported highly significant immediate post-treatment improvement in self-efficacy for coping compared to controls, although controls improved by 3 months post-treatment. However, treatment participants with lower levels of functional status benefited more than controls on depression and adjustment at follow-up. Mastery Enhancement Therapy is a time-limited treatment that increases coping efficacy and subsequently adjustment during active medical treatment, and appears to warrant a large-scale RCT with patients with below average coping self-efficacy and moderate to high symptoms.
