SCHOOL EFFECTIVENESS AND SCHOOL IMPROVEMENT, vol.22, no.3, pp.335-349, 2011 (SSCI)
Organizational citizenship behavior (OCB) has been associated with organizational effectiveness in many studies. Therefore, it is important to learn more about how these behaviors can be improved in schools. Creating a reliable and valid measure of OCB that has conceptual equivalence across cultures is a first step in understanding and accumulating systematic knowledge of this construct. This study sought to validate in a Turkish school context a three-dimensional conceptualization and measurement of OCB created by Somech and Drach-Zahavy (2000). A confirmatory factor analysis of data from a sample of 710 school teachers supported the hypothesized factorial structure of the scales. In addition, 3 subscales correlated with an organizational commitment measure in the expected magnitude and direction, which provides evidence of the predictive validity of the scales.
