Drawing on the compatibility principle in attitude theory, we propose that overall job attitude (job satisfaction and organizational commitment) provides increasingly powerful prediction of more integrative behavioral criteria (focal performance, contextual performance, lateness, absence, and turnover combined). The principle was sustained by a combination of meta-analysis and structural equations showing better fit of unified versus diversified models of meta-analytic correlations between those criteria. Overall job attitude strongly predicted a higher-order behavioral construct, defined as desirable contributions made to one's work role (r ؍ .59). Time-lagged data also supported this unified, attitude-engagement model.Job attitudes and job performance are perhaps the two most central and enduring sets of constructs in individual-level organizational research. Yet, a longstanding debate persists about the nature and the strength of relationships between these fundamental predictors and criteria (Austin & Villanova, 1992;Brief, 1998;Johns, 1998;Judge, Thoreson, Bono, & Patton, 2001). An elemental question remains: How important are job attitudes for predicting and understanding job performance in particular, and work role-directed behaviors in general?Authors of early qualitative reviews concluded that only weak support existed for the relationship between one principal attitude, job satisfaction, and supervisor ratings or output measures of job performance (e.g., Brayfield & Crockett, 1955). A common inference in those reviews was that job attitudes were more strongly related to absence, turnover, and other forms of work role withdrawal than they were to in-role performance (e.g., Herzberg, Mausner, Peterson, & Capwell, 1957;Vroom, 1964). Subsequent quantitative reviews also failed to show job attitudes as having strong predictive utility. One meta-analysis reported a lackluster value (ˆϭ .17) as the best estimate of the correlation between satisfaction and performance (Iaffaldano & Muchinsky, 1985). Another review showed organizational commitment bore a weaker relationship to job performance (ˆϭ .14) than to at least one withdrawal behavior, turnover (ˆϭ Ϫ.28;Mathieu & Zajac, 1990). Consequently, the pendulum of causal potency has swung away from job attitudes (at least until recently; see Judge et al. [2001]). One widely held view is that attitudes are inconsistent or epiphenomenal forces in work behavior (e.g., Locke & Latham, 1990): they explain only 3-4 percent of performance variance and have little practical importance for managers.The current article subjects that view to empirical scrutiny via comprehensive and comparative tests. In doing so, we attempt to contribute to management knowledge in five ways. First, we investigate and more fully map the individual-level criterion space (i.e., a set of work behaviors valued by organizations [Austin & Villanova, 1992]) by bringing four original meta-analyses to the literature, estimating the connections between contextual performance and (1) lateness, (2) a...
