In order to explore the current status and relationship of college students’ cyber-ostracism,
psychological security and interpersonal communication, 364 college students were investigated by using
Cyber-Ostracism Questionnaire for College Students, Security Questionnaire and College Students
Interpersonal Relationship Integrated Diagnostic Scale. The results showed that: (1) The incidence
of cyber-ostracism of college students is low, the psychological security is at a medium level and the
interpersonal disturbance is more serious. (2) Cyber-ostracism has a significant negative correlation with
psychological security, but a significant positive correlation with interpersonal disturbance; There was
a significant negative correlation between psychological security and interpersonal disturbance. (3) The
combination of psychological security and cyber-ostracism can significantly predict college students’
real interpersonal disturbance. The results show that cyber-ostracism increases the risk of interpersonal
disturbance, while psychological security reduces the risk of interpersonal disturbance. The purpose
of this study is to provide theoretical basis for promoting interpersonal communication among college
students from the psychological aspect
