Understanding the Role of Person-Group Fit in Driving Job Performance: A Focus on the Interaction of PG Fit

This study explores how the interactive relation of person-group (PG) fit affects job performance. From the standpoint of situation strength theory, this study hypothesizes an interactive effect of PG fit content dimensions such as value and personality fit as boundary conditions, on the relationship between PG demands-abilities (DA) fit and job performance. Our analysis finds that when the boundary condition of fit (value and personality fit) is low, the main effect of DA fit on job performance is positive. In contrast, the main effect is negative when the boundary condition is high. The present study also reexamines new phenomena often overlooked in fit studies, providing practical implications for organizational research.
