Aim: This study aimed to determine the psychological resilience and secondary traumatic stress levels of surgical nurses experiencing an earthquake and providing care to earthquake victims and to draw attention to this issue. Materials and Methods: The study with a descriptiveand cross-sectional design was conducted with 370 surgical nurses from a university hospital experiencing the earthquake and providing care to victims between May and July 2023. Data were collected by the researcher through face-to-face interviews using the Personal Information Form, the Psychological Resilience Scale(PRS), and the Secondary Traumatic Stress Scale Turkish Form (STSS). Results: The nurses scored 55.1±9.9 (min: 9, max: 83) on PRS, with sub-dimension scores of 17.8±3.9 (min: 2, max: 28) for commitment, 17.4±3.4 (min: 5, max: 27) for control, and 20.4±4.5 (min: 1, max: 29) for challenge. The STSS score was 54±12.3 (min: 17, max: 85). A weak, negative, and significant correlation was found between STSS levels (54±12.3) and PRS levels (r=-0.131, p<0.05). Conclusions: The study found high levels of secondary traumatic stress in surgical nurses who were earthquake victims and provided care to other earthquake victims. Higher stress levels were associated with lower levels of psychological resilience.
