In this study, we explore a 100 years of Work and Organizational Psychology. To do this, we carry out a bibliometric performance and network analysis to understand the evolution structure and the most important themes in the field of study. To perform the BNPA, 8,966 documents published since 1919 were exported from the Web of Science and Scopus databases. The SciMAT software was used to process data and to create the evolution structure, the strategic diagram, and the thematic network structure (...) of the strategic themes of the field of WOP. We identified 29 strategic clusters and discuss the most important themes and their relationship with other clusters. This research presents the complete evolution of the field of study, identifying emerging themes and others with a high degree of development. We hope that this work will support researchers and future research in the field of WOP. (shrink)
