This study examined relationships among job scope, perceived fit between job demands and ability, and stress. Data on scope and stress were provided by 418 full-time employees. Ratings of job complexity from the Dictionary of Occupational Titles (DOT) and the Occupational Prestige Index (OP) also measured job scope. All three job scope measures had a U-shaped curvilinear relationship with emotional exhaustion. Anxiety had a negative association with incumbent-reported job scope but none with the DOT and OP measures. Perceived demands-ability fit moderated the relationship between the DOT and OP measures and stress. People with complex jobs who perceived fit experienced less exhaustion and anxiety than those perceiving misfit.
