Specifically, it seeks to explain how self-efficacy influences employees’ thought patterns and emotional reactions, which in turn enable them to cope with work and family demands, and ultimately achieve work–life balance and work engagement. Design/methodology/approach – Structural equation modelling (SEM) of survey data obtained from a heterogeneous sample of 1,010 Australian employees is used to test the hypothesised chain mediation model. Findings – The SEM results support the hypothesised model. Self-efficacy was significantly and negatively related to work and family demands, which in turn were negatively associated with work–life balance. Work–life balance, in turn, enabled employees to be engaged in their work. Research limitations/implications – The findings support the key tenets of social cognitive theory and conservation of resources (COR) theory and demonstrate how self-efficacy can lead to work–life balance and engagement despite the presence of role demands. Study limitations (e.g., cross-sectional research design) and future research directions are discussed. Originality/value – This study incorporates COR theory with social cognitive theory to improve understanding of how self-efficacy enhances work–life balance and work engagement through a self-fulfilling cycle in which employees achieve what they believe they can accomplish, and in the process, build other skills and personal resources to manage work and family challenges.Data collection for this research was supported by the Australian Research Council Discovery Project under Grant DP0770109.application/pdfen-AU© 2017 Emerald Publishing LimitedWork engagementwork-life balanceWork psychologyHuman resource managementself-efficacyRole demands201710.1108/IJM-11-2015-01892020-11-23
