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.

Background: Nursing care, encompassing the physical, psychospiritual, sociocultural, and environmental aspects of care, should ensure patients' comfort in both chemotherapy and transarterial chemoembolization (TACE) treatment. Objective: The aim of this study was to examine the canonical correlations between perceived symptoms and interferences, barriers to symptom management, and comfort care in nurses caring for chemotherapy and TACE patients. Methods: This cross-sectional study surveyed 259 nurses caring for patients undergoing chemotherapy (n = 109) and TACE (n = 150).Fisher exact test, t tests, χ 2 tests, Pearson correlations, and canonical correlations were performed. Results: In the chemotherapy nurse group, higher perceived symptoms (R values = 0.74), higher perceived interference (R values = 0.84), and higher barriers to pain management (R values = 0.61) were associated with higher physical (R values = 0. 58) and psychological (R values = 0.88) comfort care. In the TACE nurse group, the higher the perceived symptoms and perceived interference, the lower the perceived barriers to pain management, and lower barriers to nausea/vomiting management were associated with higher physical, psychological, sociocultural, and environmental care.Conclusions: Nurses caring for TACE patients reported lower perceived symptom interference and comfort care, including physical, psychological, and environmental aspects, than those caring for chemotherapy patients. In addition, there was a canonical
