Self-esteem as moderator of the relationship between expectancies and job performance

Abstract

Examined the implication of A. K. Korman's 1970 consistency hypothesis for predictions of work behavior, derived from L. Porter and E. Lawler's expectancy model, and evaluated the feasibility of moderating the expectancy-performance relationship with relevant variables. 367 male and female managerial-level employees were subgrouped by self-esteem scores (Ghiselli's Self-Assurance Scale), and correlations between expectancies and job performance were computed. 16 of 22 correlations for the high-self-esteem groups were higher. However, only 5 of the differences were significant, thereby providing equivocal support for the consistency hypothesis. Results indicate that moderator variables may be relevant to predictions of performance with expectancy measures. (23 ref) (PsycInfo Database Record (c) 2025 APA, all rights reserved)
