Objectives: Professional identity, which is a subjective evaluation of self-determination, has been studied as an important factor in determining job satisfaction. Organizational commitment can be expected to play an important role in the relationship between professional identity and job satisfaction. The study was aimed to examine mediating effect of organizational commitment of physician assistants in the relationship between professional identity and job satisfaction. Methods: The participants of this study were 124 nurses who agreed to participate in the study among physician assistants working at two university hospitals located in B metropolitan city and Y city. The measurement tools included a questionnaire on professional identity, organizational commitment, and job satisfaction. Descriptive statistics, t-test, ANOVA, Kruskal-Wallis test, partial correlation coefficients, and multiple regression were used to analyze results. Results: The mean score of professional identity was 3.36 ± 0.42, organizational commitment was 3.28 ± 0.54, and job satisfaction was 3.12 ± 0.38. There were significant positive partial correlations between professional identity and organizational commitment (r = 0.56, p < 0.001), professional identity and job satisfaction (r = 0.65, p < 0.001), and organizational commitment and job satisfaction (r = 0.61, p < 0.001). Organizational commitment was a mediator between professional identity and job satisfaction. Conclusions: Based on this study, organizational commitment promotion strategies to improve job satisfaction are needed. These results will contribute to development of education program of a physician assistant and promotion of quality of medical services.

The purpose of this study was to examine the relationship of psychosocial wellbeing status and self leadership with job satisfaction of fire officers. The effects of these variables on job satisfaction were also examined. Methods: The study design was a descriptive, correlational design. For this study, data were collected from 189 fire officers in B metropolitan city, K and Y cities. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and multiple regression analysis with SPSS 21.0 program. Results: The results showed that job satisfaction had a significant correlation with psychosocial wellbeing status (r=-.38, p<.001) and self leadership (r=.26, p<.001). Psychosocial wellbeing status had a significant correlation with self leadership(r=-.47, p<.001). Multiple regression analysis for job satisfaction revealed that the most powerful predictor was psychosocial wellbeing status followed by self leadership. Pychosocial wellbeing status, self leadership, age, marital status and current job task career explained 25.0% of the variance in job satisfaction. Conclusion: Findings indicate that various factors are related to the job satisfaction of fire officers. Based on the results of this study, further development and application of programs to improve fire officers' job satisfaction are needed.
