Purpose: This study aimed to identify the levels of intolerance of uncertainty, rumination, self-disclosure, social support, and post-traumatic growth (PTG) among nurses at regional trauma centers. It sought to understand the relationships between these variables and determine how intolerance of uncertainty, rumination, self-disclosure, and social support influence PTG in these nurses. Methods: This study employed a cross-sectional survey design. Nurses with a minimum of three months of experience working in emergency rooms, intensive care units, and wards at five Regional trauma centers nationwide were chosen as participants. Data collection was conducted via online questionnaires from June 18, 2025, to July 17, 2025, resulting in a final total of 162 questionnaires for analysis. The questionnaire consisted of 113 items, including 9 on general characteristics, 19 on traumatic event experiences, 16 on PTG, 14 on intolerance of uncertainty, 20 on rumination, 10 on self-disclosure, and 25 on social support. The data collected were analyzed using SPSS WIN 29.0, employing descriptive statistics, t-tests, one-way ANOVA, Pearson's Correlation, and Multiple Regression analysis. Results: The results of this study are as follows 1. The average age of participants was 29.94 ± 5.01 years, and the majority were female (85.2%). Most participants reported having no religion (73.5%) and were unmarried (60.5%). The most common work setting was trauma intensive care units (42.6%). Participants had an average of 6.85 ± 5.14 years of total clinical experience, with 3.90 ± 3.20 years on average in their current department. Most participants held the position of staff nurse (92.0%), and 96 participants (59.3%) reported working in their preferred department. 2. The mean scores for key variables were as follows: traumatic event experience, 46.04 ± 8.73 (out of 76); intolerance of uncertainty, 35.31 ± 10.05 (out of 70); rumination, 39.04 ± 14.15 (out of 60); self-disclosure, 37.98 ± 14.03 (out of 70); and social support, 102.35 ± 15.00 (out of 125). The mean score for posttraumatic growth was 50.60 ± 13.70 (out of 80). Among the subfactors, the average item score for Changes in Self-Perception was the highest at 3.38±0.96, and Increased Spiritual or Religious Interest was the lowest at 2.25±1.28. 3. Analysis of differences in posttraumatic growth according to general characteristics revealed no statistically significant differences based on gender (t=-0.46, p=.652), age (F=2.33, p=.077), religion (t=1.17, p=.244), marital status (t=-1.13, p=.260), current department (F=0.16, p=.856), total clinical experience (F=2.40, p=.094), experience in current department (F=1.35, p=.263), job position (t=-0.77, p=.441), or preferred department (t=1.65, p=.101). 4. Posttraumatic growth showed statistically significant positive correlations with deliberate rumination (r=.29, p<.001), self-disclosure (r=.26, p<.001), and social support (r=.54, p<.001). 5. The factors influencing posttraumatic growth were social support (β=.50, p<.001) and deliberate rumination (β=.30, p<.001), and these variables explained 35.4% of the variance in posttraumatic growth. Conclusion: This study identified deliberate rumination and social support as factors influencing post-traumatic growth among nurses working in regional trauma centers. Based on these findings, it is expected that developing and implementing programs to enhance deliberate rumination and social support could contribute to promoting posttraumatic growth in nurses.
