入院うつ病患者に対する作業療法の効果—気分や不快な思考の改善と満足度との関係─

The effect of occupational therapy on depressed inpatients: Relationship between improvement in mood and distressing thoughts and sense of satisfaction

要旨：本研究の目的は，うつ病患者に対する作業療法の気分改善効果や不快な思考低減効果と，入院期間の関係を検討することである．対象者は精神科病院に入院中のうつ病患者105名．入院日数90日以内の回復期群と91日以上の慢性期群に分け，作業療法前後の気分および不快な思考体験とその反応を比較し，満足度との関係を分析した．気分と不快な思考の改善効果は回復期群でより良好であり，対象者の満足度に影響を与えていた．入院うつ病患者に対する作業療法において，ポジティブな気分を促す活動，集中をもたらし不快な思考を低減できるような活動の有効性が示唆された．

　The purpose of this study is to investigate the effects of occupational therapy on the improvement of moods and distressing thoughts on depressed patients. 105 depressed inpatients were classified into two groups: a) a convalescent stage group consisting patients who had been in hospital for 90 days or less, and b) a chronic stage group consisting patients who had been in hospital for 91 days or more. We analyzed their moods, distressing thoughts and their reactions to them, and their sense of satisfaction before and after occupational therapy. Occupational therapy improved their moods and reduced their distressing thoughts, and the effects on the convalescent stage group were better than that of a chronic stage group. The effects were also related to their satisfaction. Activities that lead to positive moods or reduced distressing thoughts with sufficient concentration may be effective occupational therapy for depressed inpatients.
