Existing literature indicates that job characteristics, job satisfaction, organizational commitment, and organizational citizenship behavior are very important for effective organizational functioning. Previous research on citizenship behaviors made limited contribution to the literature, since it ignored the relationships between job characteristics and citizenship behaviors together with the influences of job satisfaction and organizational commitment. The present study attempted to test a new integrative model of the relationships among job characteristics, job satisfaction, organizational commitment, and organizational citizenship behaviors. The main purpose of the present study was to examine the effects of job characteristics on organizational citizenship behaviors. While examining the role of job characteristics, the mediating roles of job satisfaction and organizational commitment were taken into account in order to better understand how job characteristics affect the exhibition of citizenship behaviors. The secondary purpose was to investigate the effects of job characteristics on job satisfaction and organizational commitment, and the effects of job satisfaction and organizational commitment on citizenship behaviors. A sample of 300 employees from 60 companies was selected. The data was collected at the location of the firms by using a survey instrument. The employees rated the items that measured task characteristics, job satisfaction, and organizational commitment. Later, the information on organizational citizenship behavior of employees was collected from the employees’ supervisors. Hierarchical regression analyses were performed on the data. In general, the findings showed that some job characteristics might be the antecedents of job satisfaction and the aggregate variable job scope was positively associated with organizational commitment, and these work attiudes predicted organizational citizenship behaviors positively. Specifically, in line with the expectations, the job characteristics of task identity, autonomy, and aggregate job scope were positively associated with the work attitude of job satisfaction. The aggregate job scope was positively associated with the work attitude of organizational commitment although no single job characteristic was significantly associated with organizational commitment. In turn, job satisfaction and organizational commitment were positively associated with the citizenship dimensions of courtesy and sportsmanship. In addition to these, organizational commitment was positively associated with the citizenship dimension of conscientiousness and aggregate citizenship behavior. However, no significant direct association was found between job characteristics and citizenship behaviors. Therefore it was not possible to test the intervening effects of work attitudes on the relationships between job characteristics and citizenship behaviors. The study’s results are discussed together with the implications, strengths and limitations. Some suggestions for future research are made.
