古典的テスト理論による日本版ADL-focused Occupation-based Neurobehavioral Evaluation（A-ONE）の信頼性と妥当性の検討

Reliability and validity of the Japanese version of the ADL-focused Occupation-based Neurobehavioral Evaluation (A-ONE) through classical test theory

要旨：日本版ADL-focused Occupation-based Neurobehavioral Evaluation（A-ONE）の信頼性と妥当性を古典的テスト理論に基づいて検討した．日本版A-ONEは，5領域22項目の日常生活活動（ADL）観察を通して，ADLを妨げている神経行動学的障害を同定する評価法である．20名の脳血管障害（CVA）患者に対して，評価者内信頼性および評価者間信頼性を検討し高いkappa係数を認めた．36名のCVA患者に日本版A-ONEと既存のADL評価および各種神経心理学的検査を実施し，併存的妥当性を検討し両者間に中等度以上の相関を認めた．これらにより，日本版A-ONEの信頼性と妥当性が確認できたと考える．今後は，CVA患者以外の対象者も含め検討していく．

　The reliability and validity of the Japanese version of the ADL-focused Occupation-based Neurobehavioral Evaluation (A-ONE J) was examined. A-ONE J can be used to evaluate both performances of activities of daily living (ADL) tasks (5 domains 22 items) and neurobehavioral problems that interfere with ADL task performances among clients with neurological disorders. Inter-rater and intra-rater reliability were examined among 20 stroke clients, and we found a high kappa coefficient. Concurrent validity was tested with 36 stroke clients. We found moderate and high correlation coefficients between A-ONE J and ADL evaluation, as well as between A-ONE J and neuropsychological tests. Our recommendations for future studies include expansion of composition, including more diverse diagnostic categories other than stroke.
