Purpose: This study aimed to determine the effect of professional self-concept on job satisfaction and occupational turnover among EMT paramedics working in medical institutions. Methods: The data collected from 161 EMT-paramedics in this descriptive correlation study using an online questionnaire form were analyzed using the SPSS 25.0 for windows statistical program. Results: The professional self-concept of the subjects was 3.78±0.61, job satisfaction rate was 3.53±0.71, and occupational turnover was 2.51±1.12 (missing value 18). Multiple regression analysis was conducted to determine the effect of professional self-concept on job satisfaction and the results were found to be statistically significant in terms of satisfaction (β=0.581, p<.001), and communication (β=0.257, p<.001). The degree to which professional self-concept explained job satisfaction was about 62% (R2=0.620). Analysis to determine the effect of professional self-concept on occupational turnover showed significant results in terms of satisfaction (β=-0.468, p<.001), and the degree to which it explained occupational turnover was about 26.6% (R2=0.266). Conclusion: The study confirmed that higher the professional self-concept, higher the job satisfaction and the lower the occupational turnover. Setting the scope of work and establishing a self-concept through professional education are necessary to increase satisfaction with work.
