Interest in health promotion has resulted in various programs designed to enhance health and prevent disease through changes in lifestyles. The effects of a widely used stress management program were analyzed in two studies. In the first study, office employees in treatment (N=21) and control (N=24) groups were administered the State-Trait Anxiety Inventory, the Profile of Mood States, the Individual Profile of Stressors, the Stress Locus of Control, and a Job Satisfaction index. Questionnaires were administered before the first stress management session, following the 12-week program, and 12 weeks after the second testing. Physiological scores were also measured. The results revealed that between the first and second testings, treatment subjects improved significantly more than control subjects on measures of trait anxiety, tension, depression, fatigue, confusions, external stress control, and job satisfaction. No significant differences were found between treatment and control groups by the third testing although in many cases both had improved. In the second study, hospital employees (N=87) enrolled in the stress management program completed the five questionnaires used in the first study and the General Well-Being Questionnaire again at three 12-week intervals. Subjects' test scores were found to have improved significantly at the second and third testings as compared to the pre-intervention scores. These findings suggest that the stress management program did produce beneficial changes although the specific reasons for improvement may be difficult to assess. (NB)
