Abstract

As job stress is now one of the biggest health-related problems in the workplace, several education programs for supervisors have been conducted to reduce job stress. We conducted a supervisor-based randomized controlled trial to evaluate the effects of an education program on their subordinates' psychological distress and job performance. The subjects were 301 employees (46 supervisors and 255 subordinates) in a Japanese sake brewery. First, we randomly allocated supervisors to the education group (24 supervisors) and the waiting-list group (22 supervisors). Then, for the allocated supervisors we introduced a single-session, 60-min education program according to the guidelines for employee mental health promotion along with training that provided consulting skills combined with role-playing exercises. We conducted pre- and post-intervention (after 3 months) surveys for all subordinates to examine psychological distress and job performance. We defined the intervention group as those subordinates whose immediate supervisors received the education, and the control group was defined as those subordinates whose supervisors did not. To evaluate the effects, we employed a repeated measures analysis of variance (ANOVA). Overall, the intervention effects (time x group) were not significant for psychological distress or job performance among both male (p=0.456 and 0.252) and female (p=0.714 and 0.106) subordinates. However, young male subordinates engaged in white-collar occupations showed significant intervention effects for psychological distress (p=0.012) and job performance (p=0.029). In conclusion, our study indicated a possible beneficial effect of supervisor education on the psychological distress and job performance of subordinates. This effect may vary according to specific groups.
