| Outline of Final Research Achievements |
To clarify effects of cognitive behavioral therapy (CBT) on depression in a workplace, we conducted randomized controlled trials (RCTs) in several enterprises. Participants were employees who worked at companies in metropolitan area of Tokyo and attended annual health examinations for two years. As results, degrees of pre-post score changes, Center for epidemiologic studies depression scales (CES-D), were significantly greater (p = 0.02) in the CBT group than in the control group, although the CES-D scores in the control group significantly increased during the study intervention. The 6-week CBT program was modified to attempt in the other study group, and significant improvement was observed for tension-anxiety (d = 0.37) and for fatigue (d = 0.60) as well. It was suggested that CBT intervention is effective in the improvement of depression as well as other psychological conditions in a workplace.
