Moreover, the maintenance of family caregivers¡¯ satisfaction with co-occupation is important to ensure that they intend to continue providing care. This study developed and validated the Measure of Supporting Co-occupation, which assesses co-occupation involving elderly people with dementia and their family caregivers. This study used a cross-sectional design and questionnaire survey. Participants were recruited from 21 institutions. Descriptive statistics were calculated for the following domains: ¡®evocation of the story of co-occupation¡¯, ¡®intention to continue co-occupation¡¯ and ¡®preferred co-occupation¡¯. The construct validity and reliability of the ¡®intention to continue co-occupation¡¯ domain were examined using exploratory factor analysis, confirmatory factor analysis and Cronbach¡¯s alpha. The criterion-related validity of the ¡®intention to continue co-occupation¡¯ was examined by means of correlations with other scales. There were 115 pairs of participants. Good criterion-related validity and internal consistency were confirmed for the ¡®intention to continue co-occupation¡¯ domain. However, confirmatory factor analysis showed insufficient model fitness. The ¡®intention to continue co-occupation¡¯ domain is not ready for clinical application due to insufficient model fitness, it is necessary to revise the Measure of Supporting Co-occupation %K Caregiving %K dementia %K outcome assessment %U https://journals.sagepub.com/doi/full/10.1177/0308022618771539
