Abstract

The main focus of this study was to investigate the relationship between the dependent variables of affective, continuance, and normative commitment and job satisfaction, job characteristics, role characteristics, and selected demographic variables. This study also aimed to make a comparison between police officers and first and mid-level supervisors of the Turkish National Police in order to test whether there was a difference between their commitment levels. The final purpose was to examine the moderating role of growth need strength (GNS) and the mediating role of overall job satisfaction between the five job characteristics and three components of organizational commitment. A total of 1,429 police officers and police supervisors were obtained and selected from various departments. An electronic survey was used to gather data from the target population. Eighteen hypotheses were developed and tested through various statistical analyses. The results revealed that role conflict and role ambiguity were inversely related to affective commitment. A positive significant relationship existed between affective commitment and tenure, task significance, autonomy, and intrinsic and extrinsic job satisfaction. The relationship between continuance commitment and education, autonomy, and role conflict were significant. Number of children, task significance, role ambiguity, intrinsic and extrinsic job satisfaction all made significant contributions to the variance in normative commitment. There was a significant difference in the level of affective, continuance, and normative commitment between police officers and mid-level supervisors and between first level supervisors and police officers. Overall job satisfaction was found to be a mediator between all five job characteristics and affective and normative commitment. Finally, GNS was a moderator between task identity and affective commitment, skill variety and continuance commitment, and job characteristics of autonomy and job feedback and normative commitment. On the whole, findings of this study revealed important theoretical, policy, and practical implications. Through an examination of the various aspects of organizational commitment and an in-depth investigation of the relationships between specific variables to components of organizational commitment, this study help researchers understand all aspects of organizational commitment from the perspective of police officers and police supervisors.
