Study of the Role of Personality Factors in Organizational Citizenship Behaviors

Organizational citizenship behavior (OCB) as a non-mandatory cooperation with others significantly influences an organization’s performance and social capital. In this paper it has been attempted to study the role of personality traits based on the Big Five model namely, extraversion, agreeableness, conscientiousness, openness to experience and neuroticism in the performing of organizational citizenship behavior, while Altruism, civic virtue, organizational conscientiousness, courtesy and sportsmanship were regarded as the main OCB dimensions. Correlation analysis on data from 56 employees of “Bank Mellat” of Tehran, revealed that there was a significant relationship between personality characteristics and OCB. The present study suggests that conscientiousness, agreeableness and emotional stability positively affect OCB. Also according to the regression model conscientiousness is the best factor to predict OCB. The current research demonstrates that neuroticism is negatively related to OCB, since it diminishes a person's ability to avoid complaining while facing organizational problems
