ABSTRACT
Role conflict and ambiguity has been the subject of both early and frequent research in the social psychological approach to occupational stress. The uncertainty model clearly associates role ambiguity with environmental information deficiency and labels the person's inability to predict as uncertainty. Role ambiguity and conflict are the results of conflicting and ambiguous expectations. Role overload is the result of a sum of expectations of activities that exceeds what is reasonable or possible. The theory of the psychological contract usually focuses on the so-called implicit contract between the person and the organization, emphasizing the fact that there are expectations beyond those in the written contract. The relationship of Person-Environment (P-E) Fit theory to the psychological contract is obvious. What is not so obvious is that P-E Fit theory is related to the role stressor category of occupational stress. The specific relationship between fit and strain may vary according to the specific type of fit being examined.
