Organizational Citizenship Behavior (OCB) involves discretionary behavior, not required or formally rewarded, that has positive consequences for the organization. The main goal of this study was to examine the role of personality dimensions as predictors of employee's engagement in help and voice OCB. Sample was integrated by 335 Argentinean employees, which were asked to complete a battery of questionnaires including demographic items, Eysenck Personality Questionnaire and Help and Voice OCB scales developed by Van Dyne and his colleagues. Stepwise regression analysis revealed that extraversion was the best predictor of the voice behavior, and emotional stability was the best predictor when help behavior was the criterion. Results partially supported the hypothetical relationship between psicoticism and voice behavior, since non psychotic tendencies only emerged as predictors of voice among females. New research agenda designed to further our understanding of personality-OCB linkages is proposed.
