Abstract

Background/aim: The Lawton Instrumental Activities of Daily Living Scale is a tool often used to assess independence among elderly at home. Its suitability to be used with the elderly population in Malaysia has not been validated. This current study aimed to assess the validity and reliability of the Lawton Instrumental Activities of Daily Living Scale – Malay Version to Malay speaking elderly in Malaysia. Methods: This study was divided into three phases: (1) translation and linguistic validity involving both forward and backward translations; (2) establishment of face validity and content validity; and (3) establishment of reliability involving inter-rater, test-retest and internal consistency analyses. Data used for these analyses were obtained by interviewing 65 elderly respondents. Results: Percentages of Content Validity Index for 4 criteria were from 88.89 to 100.0. The Cronbach α coefficient for internal consistency was 0.838. Intra-class Correlation Coefficient of inter-rater reliability and test-retest reliability was 0.957 and 0.950 respectively. Conclusions: The result shows that the Lawton Instrumental Activities of Daily Living Scale – Malay Version has excellent reliability and validity for use with the Malay speaking elderly people in Malaysia. This scale could be used by professionals to assess functional ability of elderly who live independently in community.
