Cultural Adaptation and Validation of the Japanese Environmental Assessment Tool-Higher Care

The Japanese cultural adaptation of the Australian Environmental Assessment Tool-Higher Care (J-EAT) was developed for use in Japan’s small-scale living facilities. This study aimed to validate the J-EAT. Twenty-five dementia care experts (7 gerontologists and 18 facility care workers) participated in assessing J-EAT content validity. The final version of J-EAT contained 81 items; of those, 74 met the CVI threshold for relevance. The findings indicated different perspectives between the two expert groups. Validation of the J-EAT was confirmed as an appropriate tool for Japan’s small-scale living facilities to evaluate the environment to enhance residents’ quality of life.
