A number of reports in the literature have shown the value of exercise programs in reducing depression among psychiatric patients. Most of these papers have dealt with outpatients; this paper recounts a study of hospitalized inpatients who elected to participate in a six-week exercise program. After six weeks, participants showed significant decreases in their levels of reported depression, and nonsignificant trends toward a decrease in anxiety and an increase in their sense of accomplishment. The program did not ameliorate many disturbing feelings, such as anger and fear, nor did it elicit a wide range of positive affects such as cooperation and feelings of acceptance. However, the authors conclude that a well-designed exercise program has enough potential benefit to make it a regular part of a psychiatric inpatient program.
