Development and validation of the Measure of Supporting Co

It is important to understand the experiences of elderly people with dementia and their family caregivers. 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
