The causes of organizational citizenship behavior: a motivational analysis.

This study addressed the role of motives in organizational citizenship behavior (OCB). Three motives were identified through factor analyses: prosocial values, organizational concern, and impression management. Scales that measured these motives and other variables known to covary with OCB were administered to 141 municipal employees and were correlated with self-, peer, and supervisor ratings of 5 aspects of OCB. Relative to the other motives, prosocial values motives were most strongly associated with OCB directed at individuals, and organizational concern motives were most strongly associated with OCB directed toward the organization. Each of the motives accounted for unique amounts of variance in OCB. The results suggest that motives may play an important role in OCB.
