| The potential link between Hackman and Oldham's job characteristic model and organizational citizenship behavior (OCB) was examined in a sample of 211 employees in four organizations, representing a wide variety of jobs. Four competing theories were examined using a structural equation modeling approach, looking at both direct and indirect (via critical psychological states or job satisfaction) relationships between job characteristics and OCB. Employees rated their jobs, critical psychological states, and satisfaction using the Job Diagnostic Survey. In addition, supervisors provided ratings of OCB for a subset of 182 employees. Skill variety and task significance were the only core job characteristics significantly related to OCB. The data best supported the model in which job characteristics were indirectly related to OCB via increased critical psychological states. No model accounted for significant variance in OCB, suggesting that other situational and individual differences variables may play a larger role in explaining OCB. |
