This study examined whether the effect of person-situation discrepancy on situational commitment was moderated by a person's self adjustment to the situation. The unit of inquiry consisted of dyadic working relationships between supervisors and subordinates, where the supervisors represented significant situations for the subordinates. It was hypothesized that self-adjustment interacts with person-situation discrepancy to affect situational commitment negatively. Contrary to the prediction, the results showed that the sign of the interactive effect was positive, indicating that the negative effect of personsituation discrepancy on situational commitment became less pronounced for those subordinates who had gone through greater self-adjustment in interacting with their supervisors. The meanings of the findings and directions for future research are discussed.
