A Comprehensive Meta-Analyses of the Nomological Network of Psychological Capital (PsyCap)

This paper presents the most rigorous meta-analysis undertaken to date of empirical literature examining antecedents and outcomes related psychological capital (PsyCap), moderators these relationships. We investigated seven leadership styles as PsyCap (authentic, ethical, servant, empowering, transactional, transformational, abusive leadership), five (burnout, turnover intentions, work engagement, performance, satisfaction), impact four (country sample origin, cultural characteristics, industry type, research design). Our analysis (2007–2020) examined 244 studies (254 independent samples over 96000 participants), which is twice large previous meta-analyses. To optimize quality reliability findings, we corrected for artefacts included heterogeneity, sensitivity, publication bias analyses. results provide several new findings beyond found that transactional were all positively associated with PsyCap, empowering transformational being strongest weakest. The demonstrated was negatively burnout. Country origin moderated relationships, except servant leadership. Additionally, characteristics (e.g., power distance, masculinity, long-term orientation, uncertainty avoidance) conceptual Study design also moderate PsyCap—work engagement relationship. Collectively, offer extended insights into antecedents, outcomes, theoretical practical implications are discussed.
