Effects on mood of a life-styles program for the rehabilitation of injured workers

This study reports an examination into the effects on daily mood of participation in a life-styles program by injured workers. In the current prospective study, 14 participants completed the Memorial University Mood Scale (MUMS) prior to starting the program, at 1 month, 2 months, and at 3 months. They also completed the Memorial University Scale of Happiness (MUNSH) prior to entry and after three months. There were significant improvements on the MUMS subscales of positive mood and vigor as well as overall mood. There were no changes in negative mood. Neither the positive nor the negative dispositional subscales of the MUNSH revealed any change. The results were interpreted as indicating strong psychologic benefits of the life-styles program for injured workers and are also consistent with a recently proposed two-factor state/trait model of well-being.
