Purpose : The purpose of this study was to identify the degree of occupational therapists' professional identity and examine the correlation between empowerment and burn out. We also investigated the effects of the occupational therapists' professional identity on empowerment and burn out. Through these assessments, we aimed to highlight the importance of professional identity and find methods to improve empowerment and reduce burn out in occupational therapists. Methods : The study was conducted from October 19 to from November 11, 2023. General characteristics, professional identity, empowerment, and burn out were examined using frequency analysis and descriptive statistics. The correlation between these factors was analyzed using Pearson's correlation coefficient. Multiple regression analysis was used to identify factors influencing empowerment and burn out. An α value =.05 was used to verify statistical significance. Results : First, Professional identity was an average 3.24±.37. Second, a significant correlation was found between professional identity and empowerment (r=.417, p<.01) and burn out (r=-.377, p<.01). As a result of the relationship between professional identity sub-factors and empowerment in professional organization (r=.270, p<.01),, belief in self-regulation (r=.258, p<.01), vocational consciousness (r=.348, p<.01), and belief in autonomy (r=.308, p<.01) showed a statistically significant correlation. Professional identity sub-factors were significantly correlated with burnout, professional organization (r=-.199, p<.05), belief in public service (r=-.153, p<.05), belief in self-regulation (r=-.334, p<.01), vocational consciousness (r=-.250, p<.01), and belief in autonomy (r=-.293, p<.01) showed a significant correlation. Third, professional identity sub-factors influencing empowerment were vocational consciousness (β=.154, p<.05) and belief in autonomy (β=.135, p<.05), and those influencing burnout were belief in self-regulation (β=-.389, p<.01) and belief in autonomy (β=-.244, p<.01). Conclusion : The study findings demonstrated that professional identity affects empowerment and burn out. Therefore, continuous study on the professional identity of occupational therapists is warranted.
