Evaluation of the effects of a psychosocial intervention on mood, coping, and quality of life in cancer patients.

It was hypothesized that participation in a psychosocial intervention incorporating meditation, social support, positive thinking, and a low-fat, vegetarian diet would have beneficial effects on mood, coping, and quality of life (QOL) in cancer patients. This article describes the sociodemographic, medical, and psychological characteristics of participants in a psychosocial intervention designed for cancer patients. It also describes program impact in terms of Profile of Mood States, Mini-Mental Adjustment to Cancer, and Functional Assessment of Chronic Illness Therapy. Compliance with program recommendations for 3 months and effects on adjustment were also explored. Improvements in all measures were found at program completion, with spiritual well-being particularly linked to improvement in QOL. The results suggest that the program has significant beneficial effects on adjustment but that these may not be fully maintained at follow-up, possibly because of difficulty in incorporating program recommendations into everyday life, increasing disease severity, and lack of accountability.
