Abstract
In this research on the one hand we analyzed the relationship that exists in terms of motivational persistence and the Big Five dimensions and, on the other hand, organizational citizenship behavior (OCB). The results show that the conscientiousness has been identified as being in a significant positive relationship with OCB. This result is consistent with the data provided by previous researchers. The results also indicate that three conscientiousness facets are in a positive relationship with OCB. These three conscientiousness facets are self-efficacy, cautiousness and orderliness. Agreeableness was not identified as being associated with OCB. At the level of the relationship between motivational persistence factors and OCB, we have identified a significant positive relationship with only one factor: current purpose pursuing. The OCB model has two variables that work best as predictors: high scores with regard to current purpose in terms of the pursuing-motivational persistence factor, and low scores in terms of the imagination-facet of openness to experience.
