Individual differences, psychological contract breach, and organizational citizenship behavior: A moderated mediation study

This study examines two competing theories. Self-enhancement theory predicts that self-esteem and equity sensitivity (narrow traits) increase the perception of psychological contract breach and engage less in organizational citizenship behavior (OCB), whereas self-consistency theory predicts that these two traits attenuate the perception of psychological contract breach and engage more in OCB. Agreeableness and Conscientiousness (broad traits) are expected to moderate the mediation. This study employs moderated mediation analysis to test a sample of 204 supervisor–subordinate dyads from two theme parks in northern and central Taiwan. The results show that employees high in self-esteem are less likely to perceive psychological contract breach and engage more in OCB, confirming self-consistency theory. The results also show that this mediation is observed when Agreeableness and Conscientiousness are higher than when they are lower. Theoretical and practical implications are discussed.
