A considerable amount of research has been and continues to be conducted concerning the determinants of individual job performance. A number of diverse perspectives have formed the basis of this research, including theories involving general abilities, motivation, feedback, leadership, and group processes. There is clearly a need for an integration of these theoretical perspectives so that researchers can gain a better understanding of the direct and indirect relationships associated with job performance. This article proposes a conceptual framework to guide researchers interested in the causal modeling of job performance.For a number of years, researchers in the field of organizational behavior and human resources management have been interested in understanding, predicting, and finding ways of enhancing job performance. Indeed, job performance is the single most pervasive outcome variable in microorganizational behavior research (Staw, 1984). Despite this degree of interest, the determination of job performance still remains an elusive phenomenon. The purpose of this article is to bring together the diverse literature in this area and to provide new research directions.There are several reasons for taking a closer look at the determinants of job performance. First, a number of researchers and reviewers of the literature have criticized studies for being too narrow in focus and involving too few antecedent variables (Blumberg & Pringle, 1982;Griffin, Requests for reprints should be sent to
