Abstract

Objectives: The Brief Ageing Perceptions Questionnaire (B-APQ) has five domains that explore views about own ageing. The aim of this study was to validate the B-APQ for use among older adults in Malaysia and to explore socio-demographic variations in ageing self-perceptions.Method: Older adults aged 50 years and above were randomly selected to complete a set of questionnaires. Cronbach's α was used to measure internal consistency, while corrected item-total correlations and correlation with DASS-21 and the CASP-19 scores were employed to assess convergent and discriminant validity. Confirmatory Factor Analysis (CFA) was conducted to confirm the factorial structure of the B-APQ. Difference in self-perceptions of ageing across socio-demographic variables was assessed.Results: Internal consistency for each of the domains was good. Item-total correlations within each domain were strong (>0.6) or very strong (>0.8). Convergent and discriminant validity were supported by significant correlations with DASS-21 depression and CASP-19 scores. CFA results indicated good model fit with the original B-APQ model. Presence of chronic illness also has a significant impact on B-APQ domain scores.Conclusion: The B-APQ is a valid and reliable instrument which can be used to assess self-perceptions of ageing among older Malaysian adults.
