心理危机是伴随着危机事件的发生而出现的一种心理失衡状态。各种迹象表明，随着改革开放的深入，竞争意识的增强，人们的“心理负荷”不断增加，心理危机日益增多。就大学生群体而言，心理危机也是一个不可忽视的问题。频繁发生的大学生杀人、自杀、校园暴力等现象都是大学生心理危机的外在表现。 本文在对心理危机及其相关概念进行文献研究的基础上，以西安科技大学随机抽取的600名大学生为研究对象，采用青少年生活事件量表、危机脆弱性测验问卷、危机处理方式问卷、自我压弹量表、社会支持量表等研究工具，对大学生的心理危机源、危机脆弱性以及影响危机脆弱性的因素进行了实证研究。 研究结果表明：学业压力和人际关系压力是两类最重要的大学生心理危机源；就危机脆弱性而言，36.6%的同学在面临危机时会出现不平衡的状态，10.2%的同学在面临危机时可能非常脆弱；自我压弹能力、危机处理方式、社会支持与危机脆弱性具有显著的相关关系。 在实证调查的基础上，本文还对大学生心理危机的干预策略进行了研究，提出了一些有针对性的干预措施。

Mental crisis means a state of temporary psychological unbalance taking place after a precipitating event. With the intensifying of social competition, there is evidence that people's ‘mental load’ has aggravated constantly and mental crisis increased gradually. As to university students, it also cannot be ignored. Murdering,suicide, violence frequently committed by university students are all evidences of mental crisis of them. Based on the study of related documents, this paper made a demonstration study on the headsprings and frangibility of university students, as well as factors affecting their frangibility. The testees of the survey were randomly selected from Xi’an University of Science and Technology, and the testing papers are ASLEC, ER’89, SSRS and questionnaires of crisis frangibility and crisis coping method. The result of the survey shows that stress from school work and interpersonal relations are the most important headsprings of university students' mental crisis. As far as frangibility is concerned, 36.6% of them are like to lose their balance in face of crisis events, and 10.2%of them may be very frail. And there is a negative correlativity between frangibility and ego resilience, crisis coping method, and social support. At the same time, this paper also raised some contraposing strategies on the ground of the statistics.
