Most research on person-environment fit (PE fit) takes a static approach and examines the effect of fit measured at one point in time on employee attitudes and behaviors measured at a later point in time. Recognizing the potential reverse causality (i.e., employee attitudes, behavior, and performance influence perceived fit), this study proposes a model that involves the reciprocal relationships; that is, (1) fit influences job satisfaction and job performance and (2) job satisfaction and job performance influence fit. Drawing on data collected from new hires three times over five months, we analyzed the reciprocal relationships among person-job fit (PJ fit), job satisfaction, and job performance using cross-lagged panel modeling. Our analysis supported the positive, reciprocal relationship between PJ fit and job satisfaction. Our study highlights the importance of the dynamic perspective to understand the antecedents and consequences of fit.
