MEASURING THE VALIDITY AND RELIABILITY OF THE WORK ABILITY-PERSONAL RADAR QUESTIONNAIRE USING MALAY LANGUAGE VERSION
Publication Date : 01/09/2019
The rising number of older workers in the global workforce has become a new challenge while at the same time triggering anxiety among employers with the question “how well will the workers in the near future perform concerning work demand, health and mental resources?”. Previous studies have shown the influence of age in the late phases of an individual’s work and conflict between ageing workers and the workplace. While age may not be considered a constraint in performing job task in most jobs, it is contrary when it comes to firefighting. The ageing process may indirectly increase the prevalence of work-limiting disabilities and affect work capacity and performance especially in a physically demanding job like firefighters. Thus, measuring their workability is pivotal. In this study, the Work Ability-Personal Radar (WA-PR) instrument adopted using a newly revised and modified Malay language version to assess the workability among Malaysian firefighters. As such, this paper aimed at examining the validity and reliability of WA-PR as an instrument using the Exploratory Factor Analysis (EFA) and Cronbach’s Alpha. Results from the study of WA-PR in Malay version, which have been translated and tested known as Keupayaan Kerja-Radar Peribadi (KK-RP), suggests that it can be employed and has paved the way for future studies on workability in the Malaysian context. The WA-PR instruments validated among the respondents. KK-RP showed an adequate psychometric property, making it suitable to be employed in investigating the workability level in the Malaysian context. The finding significantly can be applied in public and private sectors in Malaysia to investigate work ability among employees at the workplace.
