終末期がん患者に対する作業療法士の実践自己評価尺度の開発—妥当性・信頼性の検討

Development of the Self-Rating scale of Occupational Therapists for Terminal Cancer (SROT-TC): Examination of validity and reliability

要旨：本研究は終末期がん患者に対する作業療法士の実践自己評価尺度を開発する目的で信頼性，妥当性を検討した．緩和ケア病棟入院料届け出受理施設の作業療法士246名分を分析対象とした．結果，カテゴリカル探索的因子分析より20項目5因子構造が推定された．カテゴリカル確認的因子分析により適合度指標RMSEA＝0.067，CFI＝0.958，TLI＝0.951であり良好な構造的妥当性を有していた．ω係数＝0.8〜0.92で内的一貫性も確保された．基準関連妥当性は相関を認めたが弱かった．今後，本尺度と作業療法士の作業参加状況との関連性の検討が課題である．

　The purpose of this study was to develop the Self-Rating scale of Occupational Therapists for Terminal Cancer (SROT-TC), and to examine its reliability and validity. We analyzed 246 occupational therapists at the admission fee notification facilities in palliative care wards. As a result, five factor structures consisting of 20 items were estimated based on categorical exploratory factor analysis. The goodness-of-fit index shown by categorical confirmatory factor analysis revealed a root mean square error of approximately 0.067, a comparative fit index of 0.958, and a Tucker-Lewis index of 0.951, indicating good structural validity. Internal consistency reliability was also ensured with ω of 0.8-0.92. The criteria-related validity showed weak correlation. Future studies need to examine the relationship between the SROT-TC and occupational participation status among occupational therapists.
