Psychological capital and work–home enrichment: job crafting as a mediator

Purpose Based on the Job Demands-Resources theory, this study investigates whether psychological capital (PsyCap) is a precursor of the one-directional work-to-home enrichment (WHE) process through a parallel mediation mechanism enabled by promotion-focused job crafting components. Design/methodology/approach A cross-sectional study was conducted on 231 Romanian employees. Data were analyzed using structural equation modeling (SEM). Findings PsyCap (what I can do) is an antecedent of all three promotion-focused job crafting behaviors (what I actually do) and WHE. Two specific job crafting dimensions – increasing social job resources and increasing challenging job demands – fully mediate the link between PsyCap and WHE. Increasing structural job resources does not predict WHE. Originality/value This study identifies PsyCap as an antecedent of WHE. It also uncovers underlying behavioral mechanisms that enable the transfer of resources from the work role to individuals' home role by investigating job crafting components as distinct dimensions. As such, it gives practitioners a clearer understanding of which behaviors they should seek to cultivate for employees to potentiate their home role through aspects of their job.
