Outline of Final Research Achievements

We examined the validity of the use of a housing environment assessment that can assess a combination of physical capacities and the housing environment for older adults requiring long-term care services in Japan. In Study 1, a scoping review was conducted to elucidate the validation process of the housing assessments that had already been scientifically validated in Asian countries or regions. Two assessments were found, but these were not verified for the criterion-related validity. In Study 2, housing environment assessments were classified based on the International Classification of Functioning, Disability, and Health. However, it was impossible to categorize the housing environment items because of differences in the level of abstraction. Therefore, we used the classification framework developed in Study 1, and eight of the nine items could be classified. We finalized the housing environment assessment that was validated in Japan through this research project.

Academic Significance and Societal Importance of the Research Achievements

日本における妥当性検証を経た住環境評価指標を完成させることができた。既存の住環境評価指標は、転倒予防を目的に住環境ハザードを評価することに主眼を置いている中で、本評価指標では要介護高齢者のアクセシビリティを評価することが可能となる。今後、スコアリングの妥当性、信頼性を検証し、本評価指標を用いた調査が行えれば、住環境の危険性を認知するだけでなく、要介護高齢者の残存能力を生かす住環境アクセシビリティの視点からの住環境政策への提言につながる。日本ではほとんど行われていない住環境アクセシビリティの実態把握につながるという点で本研究成果は学術的、社会的に意義がある。
