回復期リハビリテーション病棟における認知機能障害者のQOLに対するADL，作業適応，性格特性の影響—構造方程式モデリングを用いた検討

Effects of ADL, occupational adaptation, and personality on QOL of patients with cognitive impairment in convalescent rehabilitation wards: A structural equation modeling approach

要旨：本研究の目的は，認知機能障害者のQOLに対して，ADL，作業適応，性格特性がどのように影響するのかを検証することである．対象者は回復期リハビリテーション病棟に入棟している87名とした．横断研究デザインを用い，先行研究に基づいて作成した仮説モデルを構造方程式モデリングで検討した．結果，最終モデルの適合度はCFI＝0.927，RMSEA＝0.051となった．標準化係数はADLからQOLが0.56，作業適応からQOLが0.54となり，有意となった．認知機能障害者のQOLに対して，作業適応の向上を図ることが，ADLの向上と同程度の影響を与えることが明らかとなった．

　The purpose of this study was to verify the effects of ADL, Occupational adaptation, and personality on the QOL of cognitively impaired patients. The subjects were 87 patients in a recovery phase rehabilitation ward. A cross-sectional research design was used, and a hypothetical model based on previous studies was examined by structural equation modeling. As a result, the appropriateness of fit of the final model was CFI=0.927 and RMSEA=0.051. The standardized coefficients were 0.56 for ADL to QOL and 0.54 for Occupational adaptation to QOL, which were significant. It was found that improving Occupational adaptation had as much effect on the QOL of cognitively impaired patients as improving ADL.
