Malaysia aims to be one of the developed nations by year 2020; therefore, it is crucial to gauge the quality of working life in a parallel manner using a well-established Work-Related Quality of Life (WRQoL) Scale. The goal of this study is to describe the validity and psychometric properties of the Malay WRQoL Scale in Malaysian population.
A total of 572 respondents took part in this cross-sectional study giving a 97% response rate. The reliability of the Malay WRQoL Scale was assessed using the test retest reliability analysis after a 2-week period. Both the interclass correlation (ICC) and Cronbach's alpha were within acceptable levels. However in the validity analysis, the exploratory factor analysis only revealed 5 factors instead of 6 in the original scale.
The Malay WRQoL scale has demonstrated to have the appropriate psychometric properties and can therefore be used in Malaysia to assess the quality of working life.
