This study aimed to explore the mediating effect of Borderline Personality Traits (BPT) on the relationship between self-compassion and rejection sensitivity with interpersonal problems. <strong>Method:</strong> This cross-sectional study employed a descriptive-correlational design analyzed through path analysis to test mediation effects. The statistical population comprised students from Tabriz Azad Medical Sciences University during the second quarter of 2024. A total of 200 individuals were recruited using a convenience sampling method. Study measures were the Self-Compassion Scale, the Interpersonal Problems Questionnaire, the Rejection Sensitivity Scale, and the Borderline Personality Disorder Scale. Data analysis was performed using Pearson's correlation coefficient with SPSS-26 and path analysis with AMOS-20. <strong>Results:</strong> The findings revealed that interpersonal problems had a significant negative correlation with self-compassion and a positive correlation with rejection sensitivity. Additionally, BPT were significantly associated with interpersonal problems. Path analysis indicated that rejection sensitivity (p=0.05, β= -0.21) and self-compassion (p = 0.05, β = -0.58) indirectly influenced interpersonal problems through borderline traits. The model demonstrated a good fit with the data. <strong>Conclusion:</strong> The findings show that rejection sensitivity and self-compassion indirectly influence interpersonal problems through BPT. The findings underscore the potential for developing targeted interventions to address interpersonal difficulties. https://www.behavsci.ir/article_223973_bf9c9e49c53237be999cca14efe1cc23.pdf
