Jackson and Schuler (1985) revisited: A meta-analysis of the relationshipsbetween role ambiguity, role conflict, and job performance

We conducted a metal-analysis of correlations between role ambiguity and jo b performance and role conflict and job performance. Previous meta-analyses of these role constructs and performance relationships (e.g., Jackson & Sc huler; 1985) were limited by small sample sizes and sparse reporting of rel iability estimates in primary studies. The present study used a comprehensi ve database with a larger sample size and a distribution of interrater reli abilities to extend the previous findings. We also tested moderator hypothe ses proposed but not conducted by Jackson ann Schuler: Results revealed a n egative relationship (rho = -.21) between role ambiguity and job performanc e with moderating influences due to job type and rating source. A negligibl e relationship (rho = -.07) was observed for role conflict and job performa nce, a finding consistent across job types and rating sources. Conclusions were that role ambiguity ought not to Dr dismissed as an unimportant variab le ill the job performance domain. (C) 2000 Elsevier Science Inc. All right s reserved.
