Abstract

OBJECTIVE: This study aimed to determine the psychometric properties of the Bahasa Malaysia (BM) version of the Older Americans Resources and Services-Instrumental Activities of Daily Living (OARS-IADL) questionnaire among older persons in Malaysia.

METHODS: The English version of OARS-IADL was translated to BM. The psychometric properties of the BM version of OARS-IADL were tested among older persons attending a health-care facility.

RESULTS: Two hundred and seventy-one older persons participated in the study. The mean age of participants was 67.7 ± 6.1 years. Internal consistency of the items was good (Cronbach's alpha, >0.7). Exploratory factor analysis revealed a single dimension with item factor loadings of >0.5. Confirmatory factor analysis results confirmed a single-factor model (AVE > 50%, CR > 0.7 and CR > AVE).

CONCLUSION: The BM version of the OARS-IADL questionnaire is a valid and reliable instrument that can be used to assess the IADL among older persons in Malaysia.
