Abstract

Objective This study aimed to construct and validate the Work-Related Quality of Life Scale-2 (WRQoLS-2) for use in Indonesia.

Methods A cross-cultural adaptation process, including forward and backward translations by multilingual experts, ensured linguistic and conceptual equivalence of the items. Six nursing experts assessed the content validity, and the reliability was tested using Cronbach’s alpha, Intraclass Correlation Coefficients (ICCs), and Spearman rank correlation coefficients among 38 registered nurses.

Results The Indonesian WRQoLS-2 showed strong content validity (S-CVI/Ave of 0.97, S-CVI/AU of 0.84) and high internal consistency (Cronbach’s alpha: 0.955-0.961). The ICC analysis yielded an overall ICC of 0.921, indicating excellent reliability. Most dimensions showed positive Spearman correlations, with the exception of three items in the Stress at Work dimension, which were revised and retested. The revised items confirmed that there were no comprehension issues vis-à-vis the questionnaire.

Conclusions Overall, the Indonesian version of the WRQoLS-2 proved to be a valid and reliable tool for assessing the quality of work life among hospital personnel in Indonesia.
