Study conducted to determine the validity of the Chinese version of the Challenging Behavior Scale (CCBS) when used to assess clients with dementia in residential care settings. The CCBS was designed to measure resident behaviors in long term care facilities. The assessment defines challenging behavior as “behavior of such an intensity, duration, or frequency that the physical safety of the person or another is placed in serious jeopardy, or behavior which is likely to seriously limit or deny access to ordinary community facilities.” The assessment covers both global and specific behaviors in residents with dementia such as lack of occupation, agitation, aggression, eating, and sleep issues. These behaviors are explained in plain terms, as the CBS can be used by both trained and untrained formal caregivers, which makes it especially useful in residential settings. A total of 125 people from three residential care facilities in Hong Kong participated in the study. The CCBS was administered together with the Cantonese version of Mini-Mental State Examination, the Clinical Dementia Rating, the Disability Assessment for Dementia, and the Neuropsychiatric Inventory in order to explore the relationships between challenging behavior and important clinical correlates. The CCBS was found to have good internal consistency, inter-rater reliability, and good test-retest reliability. Challenging behaviors were found to be associated with male gender, cognitive impairment, functional disability, neuropsychiatric symptoms, and higher caregiver workload. Ultimately, the CCBS was found to be a valid and reliable measure to assess challenging behavior among people with dementia in residential care settings in a local Chinese community. The measure was also found to be useful in evaluating the challenges faced by formal caregivers during daily care of clients with dementia. This study was conducted in residential facilities in the Tuen Mun district in Hong Kong from August 2004 to July 2005.
