Abstract:
The research was a cross-sectional study with the objective of studying factors influencing the organizational commitment of registered nurses in a university hospital in Thailand. The studied sample were 354 registered nurses who had been working in the hospital for not less than one year. Data was collected by using questionnaires between 15-30 June 2555 B.E. There were 341 returned questionnaires (96.33%), statistical analysis of the data was done by using descriptive statistics, chisquare and binary logistic regression. The study found that the registered nurses in the university hospital in Thailand had high level of: working motivation, perception of organizational climate and organizational commitment. Factors which were associated with organizational commitment (p < 0.05) were age, marital status, working position, duration of work, working motivation factors and perception of organization climate. Factors which had influence over the organizational commitment of the registered nurses were duration of work, working motivation factors in aspects of the work itself and achievement, perception of organizational climate in aspects of context. These factors could influence the variation of organizational commitment of the registered nurses by 35 percent (p < 0.05). Thus the administration should promote and support working motivation factors and the perception of organization climate by creating a working value for the registered nurses, specific to the identity of the hospital. Thus the registered nurses would be working with enthusiasm at work, have trust in the organization, make sacrifices and be willing to work, have a positive attitude, be loyal and remain working with the organization.
