要旨：本研究は，筆者らが開発した「作業に焦点を当てた作業療法実践自己効力感尺度」の信頼性・妥当性を検討した．対象は日本国内の作業療法士と作業療法学生とし，オンラインアンケートを用いて246名の回答を得た．探索的因子分析の結果，31項目3因子構造であることが推察された．この予測をもとに共分散構造分析を実施したところ，適合度指標CFI＝.911で十分な適合度が確認され，RMSEA＝.096は適合度が良いとは言えなかったが，一定の妥当性が確認された．各因子のCronbach's αは.970〜.981で内的整合性が保たれていた． This study investigated the reliability and validity of “The Scale of Self-Efficacy of Occupation focused Practice.” Subjects were registered occupational therapists and occupational therapy students in Japan. Effective responses were provided from 246 subjects using a web questionnaire. Factor analysis revealed 31 items and 3 factor structures. Covariance structure analysis based on this prediction indicated confirmation of model fitness with the goodness-of-fit index CFI=.911, while RMSEA=.096 was not a good fit. However, a certain level of construct validity was confirmed. Internal consistency reliability was evaluated using Cronbach's α coefficient. Cronbach's α of each factor were .970-.981, indicating that our developed scale was reliable and valid.
