Collective psychological capital: A systematic review and meta-analysis of studies adopting the Psychological Capital Questionnaire

This paper presents a novel systematic review and meta-analysis of the empirical literature on collective Psychological Capital at the team and organisational levels. In doing so, it complements previous reviews that have focused exclusively on individual-level psychological capital. Drawing on empirical research from published and unpublished studies conducted between 2007 and 2024 that used the Psychological Capital Questionnaire, this paper provides an understanding of the nomological network of variables related to collective psychological capital at both the team and organisational levels. Findings from the meta-analyses demonstrate that shared leadership and leader humility are positively associated with team-level psychological capital. They also indicate that team-level psychological capital is positively related to outcomes including team performance, team innovation, team learning, and organisational citizenship behaviour. Based on these findings, a future research agenda is proposed to facilitate both theoretical and empirical advances in knowledge of collective psychological capital.
