Abstract: Functional evaluation of individuals with dementia has long been recognized as an essential element of rehabilitation process. The aim of this study is to establish the validity and reliability of the Chinese version of the Activities of Daily Living Questionnaire (ADLQ-CV). The Activities of Daily Living Questionnaire is a 28-item informant-rated measure designed to assess the functional performance in basic and instrumental activities of daily living in the dementia population. The content validity of the ADLQ-CV was determined using an expert panel. Three items including home maintenance, home repair and organizations, were identified as less culturally relevant and representative for Hong Kong Chinese elderly, and hence these items were eliminated. The 25-item ADLQ-CV was administered to primary family care-givers of 125 community-dwelling older adults with dementia. A factor analysis yielded six factors that closely resembled the six subscales proposed by the original authors of the scale. The ADLQ-CV demonstrated excellent convergent validity with the Chinese version of the Disability Assessment for Dementia (r = - 0.917, p<0.01). The internal consistency of the ADLQ-CV was good (Cronbach's alpha = 0.813). The test-retest reliability was excellent (ICC = 0.998) and excellent inter-rater reliability (ICC = 0.997) of the ADLQ-CV was obtained. The ADLQ-CV shown a significant negative association with the global mental state (r = - 0.799, p<0.01), yet, it did not correlate with age, gender or educational level of individuals with dementia. The findings suggest that the ADLQ-CV is a valid and reliable instrument to evaluate the functional capabilities of older Hong Kong Chinese adults with dementia.
