Abstract: | We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined. |
