Abstract
The purpose of this study was to investigate how to maintain the mental health of staff members working at social welfare facilities caring for patients with mental disabilities. Our special focus was work control and work generated stress. A total of 175 staff members completed the evaluators for work stress level, work control (both method control and goal control), job dissatisfaction. Analysis of the results showed that work stress levels were affected by the weight and difficulty of the job. The results of three ways ANOVA indicated that the interaction between having control of work methodology and goals moderated job dissatisfaction. The staff member's mental health was best maintained in a work environment where control of both work methods and goal setting were in their own hands.
