The CASP-19 is an age-specific measure of quality of life. It comprises four domains: control, autonomy, self-realisation and pleasure, and is widely used in large cohort studies in temperate climates. Our objective was to translate the CASP-19 into Bahasa Malaysia and validate it for use in older Malaysians in their three commonly used languages of English, Bahasa Malaysia and Traditional Chinese. CASP-19 showed good internal consistency and test-retest reliability with acceptable construct validity compared with the 12-item short-form health survey. Factor analysis found the best fit for the Taiwanese five-domain model. The validity of CASP-19 may be limited by cultural differences.
