うつ状態勤労者の復職支援を目的とした集団精神療法の効果

Effectiveness of Group Psychotherapy in Workers with Depression

抄録

　うつ病やうつ状態による休職者が増加しているが，復職後の再休職率が高いことが知られている。そのため現在リワーク活動が全国の精神科関連施設などで行われている。しかし，リワーク活動期間が長く，多くの勤労者を対象にできないといった課題も挙げられる。当院では復職支援を目指した短期集団精神療法プログラムを行っている。今回48例のうつ状態で休職となった勤労者を対象に短期集団精神療法の効果について検討した。プログラム受講後に48例中34例(70.8％)が復職可能となった。復職した勤労者の34例中30例(88.2％)が1年間の復職継続が可能だった。

　本結果から短期集団精神療法プログラムは一部の患者には有用であると考えられた。

Even after the depressive state has been improved, it can still be difficult for patients with depression to re-join at work. The aim of this study was to investigate the long-term effectiveness of 9-session weekly group psychotherapy on patients with depression. A total of 48 patients with depression were enrolled. There were 45 male participants and 3 female participants. The group psychotherapy involved 9 weekly 1.5-hour group sessions. The Hamilton Depression Scale (HAM-D) and Social Adaptation Self-evaluation Scale (SASS) were used to evaluate the patients before and after completion of the study. This study was approved by the Ethics Committee of the University of Occupational and Environmental Health. The main findings were as follows：(1) All participants finished all 9 sessions. (2) 70.8% of the participants returned to work. (3) After group psychotherapy, the average HAM-D score and SASS scores were significantly improved. (4) 88.2% of the participants who returned to work continued working. These findings demonstrate that group psychotherapy for workers with depression reduces depressive symptoms and social adaptation and helps them to continue working.
