reported that personality measures are weaker predictors of OCB when compared to attitudinal predictors (Organ & Ryan, 1995). Task characteristics such as feedback, routinization, and intrinsic satisfaction are found to be significantly related to altruism, courtesy, conscientiousness, sportsmanship, and civic virtue. Positive relationships were found between both task feedback and intrinsic satisfaction and OCB, while a negative relationship was found between task routinization and OCB. Even though task characteristics have been found to predict OCB, some debate exists as to whether this is a direct effect or a relationship mediated by job satisfaction (Todd & Kent, 2006). Leadership behaviors have also been found to be an important predictor of OCB. These behaviors fall into four categories: transformational leadership behavior, transactional leadership behavior, behaviors having to do with the path-goal theory of leadership, and behaviors having to do with the leader-member exchange theory. Transformational leadership behaviors, including articulating a vision, providing an appropriate model, fostering the acceptance of group goals, high performance expectations, and intellectual stimulation, have significant positive relationships with Organ's dimensions of OCB. Two types of behaviors representative of transactional leadership style, contingent reward behavior and non-contingent punishment behavior, have significant relationships with Organ's dimensions of OCB. Additionally, both the supportive leadership and leader role clarification aspects of the path-goal theory of leadership are positively related to OCB. Podsakoff et al. (2000) found that leader-member exchange was positively related to altruism and an overall composite measure of OCB. Consequences During the early 1990s, scholars gained real momentum in the area of OCB with regard to empirical research. Empirical research regarding the consequences of OCBs has focused on two main areas: organizational performance and success and managerial evaluations of performance and reward allocation. Some evidence also exists on the impacts of OCB on the employees themselves. Organizational performance and success Multiple studies and meta-analyses have been conducted to look at the relationship between OCBs and organizational performance and success. Podsakoff and MacKenzie (1994, as cited in Organ et al., 2006) looked at an insurance agency and found that the OCBs civic virtue and sportsmanship were both significantly related to indices of sales performance. Podsakoff, Ahearne, and MacKenzie (1997, as cited in Organ et al., 2006) examined paper mill workers and found that helping behavior was significantly related to product quality. MacKenzie, Podsakoff, and Ahearne (1996, as cited in Organ et al., 2006) found that civic virtue and helping behavior were
