Career decision-making difficulties are a common challenge for college students, which can hinder their transition from education to employment. Based on the Social Cognitive Model of Career Self-Management, this study explored how social support was related to career decision-making difficulties. A total of 991 vocational college students participated in this cross-sectional quantitative study. Social support was measured through the Perceived Social Support Scale, career decision-making self-efficacy with the Career Decision-Making Self-Efficacy Questionnaire, job search clarity via the Job Search Clarity Questionnaire, career decision-making difficulties using the Career Decision-Making Difficulties Questionnaire, and proactive personality by the Proactive Personality Scale. The results showed that: Job search clarity partially mediates the relationship between social support and career decision-making difficulties. The indirect effect was significant, β = −0.08, p

职业决策困难是大学生面临的普遍挑战，会阻碍其完成从学业到职业的过渡。本研究基于职业自我管理社会认知模型（Social Cognitive Model of Career Self-Management），探讨了社会支持与职业决策困难之间的关联。本次横断面量化研究共招募991名高职院校学生参与。研究采用领悟社会支持量表（Perceived Social Support Scale）对社会支持进行测量，通过职业决策自我效能量表（Career Decision-Making Self-Efficacy Questionnaire）评估职业决策自我效能，借助求职清晰度问卷（Job Search Clarity Questionnaire）评定求职清晰度，以职业决策困难问卷（Career Decision-Making Difficulties Questionnaire）衡量职业决策困难程度，并使用主动性人格量表（Proactive Personality Scale）测量主动性人格。研究结果表明：求职清晰度在社会支持与职业决策困难之间发挥部分中介作用，间接效应显著，β = −0.08，p
