Outline of Final Research Achievements

This study developed the Toileting Behaviour Evaluation (TBE), a novel assessment tool designed to evaluate each component of toileting behavior in patients with cognitive and perceptual dysfunction. The reliability and validity of the scale were confirmed using both classical test theory and Rasch analysis. Additionally, using the TBE, we assessed toileting behavior in stroke patients and identified key factors influencing the ability to pull up lower garments, a common area of difficulty. Predictive values for functional outcomes were also explored. Based on these findings, a preliminary support program was drafted to guide clinical interventions in toileting rehabilitation.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は、従来の評価尺度では把握が困難であったトイレ動作の詳細な分析を可能にする新たな評価尺度（TBE）を開発し、その心理測定特性を理論的・統計的に検証した点にある。また、動作ごとの困難性や予後予測因子の解明により、エビデンスに基づく作業療法の実践に貢献する。社会的意義としては、高齢化が進む中で在宅生活を支えるトイレ動作支援の質を向上させ、退院支援や在宅介護の現場での実用的な支援策の構築に寄与する点が挙げられる。
