Abstract

The Work–Life Boundary Enactment Scale (WLBES), developed by Wepfer et al. (2018), measures the extent to which individuals behaviourally integrate or segment work and personal life through two dimensions: work-to-life integration and life-to-work integration. Although the WLBES has been used in several Indonesian studies, we found no prior study that tested its factor structure with a confirmatory approach in an Indonesian working population. This study examined the factorial validity of the Indonesian-adapted WLBES, one component of construct validity, using Confirmatory Factor Analysis (CFA). A total of 629 full-time employees in Indonesia (422 women, 67.09%; 207 men, 32.91%; aged 18–42 years) were recruited through convenience sampling. Data were analyzed in LISREL 8.80. Unidimensionality was tested with a separate one-factor CFA for each dimension; a joint two-factor model was not estimated. For work-to-life integration, χ²(5) = 27.68, p < .001, RMSEA = 0.086, CFI = 0.99, SRMR = 0.028. For life-to-work integration, χ²(5) = 28.75, p < .001, RMSEA = 0.089, CFI = 0.99, SRMR = 0.022. Incremental and residual-based indices indicated good fit, while RMSEA indicated marginal fit. All ten items had significant standardized factor loadings (0.61–0.83; t > 1.96). Cronbach's alpha was 0.844 for work-to-life integration and 0.864 for life-to-work integration. These results provide initial support for the unidimensionality of each WLBES dimension and for adequate internal consistency in this convenience sample. Convergent and discriminant validity, the joint two-factor structure, and measurement invariance were not examined and should be tested in future research.
