Purpose: This study aimed to identify the effects of emotional intelligence and self-leadership on job satisfaction among physician assistant nurses. Methods: The participants were 146 physician assistant nurses working at two university hospitals. Data were collected from August 1-September 31, 2020 and analyzed through t-test, ANOVA, Scheffé test, Pearson correlation, and hierarchical regression analysis using SPSS/WIN version 26.0. Results: Factors affecting job satisfaction were self-leadership (β=.30, p=.003), “less than 1 year of experience as a physician assistant nurse” (β=.27, p=.025), and emotional intelligence (β=.25, p=.007), and the explanatory power was 34.4% (F=6.03, p<.001). Conclusion: Our study shows that self-leadership and emotional intelligence play a significant role in the job satisfaction of physician assistant nurses; thus, strengthening these two factors is crucial to improve the nurses’ job satisfaction. The results of this study may serve as basic data for the development of strategies to enhance job satisfaction among physician assistant nurses.

Purpose: This study aimed to identify the predictors of psychological well-being in middle-aged female workers by examining the relationship between positive psychological capital, job stress, and job satisfaction. Methods: Data were collected from 145 middle-aged female workers. A self-report questionnaire was used to assess the level of positive psychological capital, job stress, job satisfaction, and psychological well-being. SPSS/WIN version 23.0 was employed for data analysis. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficient, and multiple regression. Results: The most significant predictors of psychological well-being in the participants were positive psychological capital, living standards, and hobby. These explained 39% of the variance for psychological well-being. Conclusion: We found that positive psychological capital, living standards, and hobby influenced the participants’ psychological well-being. Therefore, to improve middle-aged female workers’ psychological well-being, developing a program based on positive psychological capital management is necessary.
