回復期リハビリテーション病棟脳卒中患者における，抑うつ症状と意味のある作業の満足度，自己効力感との関連

Relationship between depressive symptoms, satisfaction with meaningful occupation, and self-efficacy for stroke patients in the recovery rehabilitation phase

要旨：本研究では，回復期リハビリテーション病棟（以下，回復期病棟）入院中の脳卒中後うつ症状（以下，PSD）患者において，意味のある作業の満足度が自己効力感の変化量を媒介し，うつ症状を軽減するかを調査した．72名の対象者の入院時と退院時間における，うつ症状，意味のある作業の満足度，自己効力感のスコアの変化量について媒介分析を行った．その結果，意味のある作業の満足度は，自己効力感を媒介することなく，うつ症状に有意な直接効果を示した（β＝−2.5，95%CI［−4.2，−0.86］，p＝0.004）．この結果から，意味のある作業の満足度は，回復期病棟におけるPSDの軽減に寄与する可能性が示唆された．

　The aim of this study was to verify whether satisfaction with meaningful occupation mediates self-efficacy and reduces depressive symptoms for post-stroke depression (PSD) patients in the recovery rehabilitation phase. We used a mediation analysis of the change in depressive symptoms, satisfaction with meaningful occupation, and self-efficacy scores between admission and discharge in 72 patients. The results showed that satisfaction with meaningful occupation had a significant direct effect on depressive symptoms without mediating self-efficacy (β=−2.5, 95%CI [−4.2, −0.86], p=0.004). The results suggest that satisfaction with meaningful occupation may contribute to the reduction of PSD in the recovery rehabilitation phase.
