The nature and dimensionality of organizational citizenship behavior: A critical review and meta-analysis.

This article reviews the literature on organizational citizenship behavior (OCB) and its dimensions as proposed by D. W. Organ (1988) and other scholars. Although it is assumed that the behavioral dimensions of OCB are distinct from one another, past research has not assessed this assumption beyond factor analysis. Using meta-analysis, the authors demonstrate that there are strong relationships among most of the dimensions and that the dimensions have equivalent relationships with the predictors (job satisfaction, organizational commitment, fairness, trait conscientiousness, and leader support) most often considered by OCB scholars. Implications of these results are discussed with respect to how the OCB construct should be conceptualized and measured in the future.
