• Abstract: This study focused on the domain of interpersonal relationships, examining the association between intolerance of uncertainty on individuals’ interpersonal relationship satisfaction and its underlying psychological mechanisms. A serial mediation model involving self-expansion preference and self-concept clarity was constructed. A sample of 328 college students participated in this study, and a cross-sectional design was employed to investigate the relationships among these variables. The results indicated that intolerance of uncertainty significantly and negatively predicted individuals’ interpersonal relationship satisfaction. Both self-expansion preference and self-concept clarity independently mediated the relationship between intolerance of uncertainty and interpersonal relationship satisfaction. Moreover, the serial indirect effect through self-expansion preference and self-concept clarity was significant, such that intolerance of uncertainty reduced interpersonal relationship satisfaction sequentially by constraining self-expansion preference and decreasing self-concept clarity. These findings extend the application of intolerance of uncertainty theory to a novel domain and offer potential intervention pathways, centered on modifying cognitive appraisal and motivational processes, for enhancing college students’ interpersonal relationship satisfaction, particularly for those with high levels of intolerance of uncertainty. 本研究聚焦人际关系领域，考察难以忍受不确定性对个体人际关系满意度的影响及其内在心理机制，构建了自我扩展偏好与自我概念清晰性的链式中介模型。研究以328名大学生为研究对象，应用横断设计调查了各变量之间的关联，结果表明：难以忍受不确定性对人际关系满意度存在显著的负向预测作用；自我扩展偏好与自我概念清晰性分别在二者之间起独立中介作用；自我扩展偏好与自我概念清晰性的链式中介作用显著，即难以忍受不确定性依次通过抑制自我扩展偏好和降低自我概念清晰性，最终损害人际关系满意度。研究结果拓展了难以忍受不确定性理论的应用领域，同时为提升大学生人际关系满意度，尤其是针对高难以忍受不确定性群体的干预，指明了认知与动机导向的潜在路径。
