Abstract:
The implementation of strategies to achieve an ideal work-life balance (WLB) is increasingly regarded as crucial for enhancing worker well-being and productivity. This study aimed to develop the Work Life Efficacy Scale (WLES) and validate its reliability and validity in measuring self-efficacy in managing WLB. The WLES was developed through extensive interviews with 10 corporate employees and a literature review to ensure content validity. Data were collected through an online survey with 1412 working-age individuals. The scale's content validity, structural validity, internal consistency, criterion-related validity, and construct validity were assessed. Results supported a three-factor structure based on factor loadings, communality, and uniqueness, and demonstrated good model fit with excellent fit indices, supporting structural validity. High internal consistency was also noted. Convergent validity was supported, and discriminant validity was generally supported, despite partial overlap observed. Criterion-related validity was confirmed by positive correlations with life satisfaction, work productivity, work engagement, and work-family balance, and a negative correlation with turnover intention. Overall, the WLES is an effective new work-life efficacy scale encompassing work-life autonomy and harmony toward achieving an ideal WLB. It could serve as an important resource for organizations seeking to increase employee satisfaction and retention through improved WLB management.
