ABSTRACT

Aim: This study aims to develop items of a home modification assessment based on Korean home and life styles based on a Delphi survey. Methods: A literature review regarding a home modification assessment was conducted and a professional focus-group was established. The participants went through a review of items, descriptive opinions were collected, and the items were scrutinized through an active discussion. A modified Delphi method was applied in this study. The first Delphi was conducted for a total of 13 of the occupational therapists and professors who are currently working in the home modification field. Finally, the final items were selected and the stability, convergence, consensus and content validity ratio (CVR) were calculated. Results: At the initial item construction, the items were separated into multi-unit and detached house types. There were no deleted items after the first Delphi, the expressions were polished, and some of the items were immerged and a new item was added. Finally, 56 items of 9 domains for the multi-unit type were confirmed and 62 items of the 10 domains for the detached house type were confirmed after the second Delphi survey. The average CVR was 0.99; stability, 0.12; convergence, 0.26; and consensus, 0.89 among the multi-unit type items. In addition, the average CVR was 1.00; stability, 0.11; convergence, 0.28; and consensus, 0.72 among the detached house type items. Conclusion: This study was conducted to develop the items of home safety and fall issues based on Korean home and life styles. The items established through a validation by a Delphi survey were highly valid and stable for use in clinical practice in Korea.
