Analysing mediating effects underlying the relationships between P–O fit, P–J fit, and organisational commitment

Abstract

Person–Organisation fit (P–O fit) and Person–Job fit (P–J fit) are important predictors of employees’ commitment to their organisations. Yet little is known about the underlying mediating variables that account for these relationships. Based on assumptions derived from Social Exchange Theory (SET) and Social Identity Theory (SIT), the present study predicts that the effects of P–J fit and P–O fit on employee commitment are mediated by job satisfaction and organisational identification, respectively. An online survey (N = 432 employees) was used to test the proposed relationships using a series of path models in AMOS. As expected, P–O fit and P–J fit are positively related to affective, normative, and continuance commitment, with P–O fit showing stronger effects than P–J fit. Organisational identification and job satisfaction completely mediate the effects of fit on the commitment facets. Evidence of differential effects for P–O fit and P–J fit suggest that different forms of fit operate in different ways to influence facets of organisational commitment. This knowledge can be helpful for advancing the integration of SIT and SET in the context of the employee–organisation relationship and for designing interventions to foster organisational commitment.
