Abstract: Objective To explore the characteristics of interpersonal harassment and its influencing factors in freshmen and sophomores.Methods With stratified cluster sampling,1 103 freshmen and sophomores were selected from universities in Gansu province and surveyed with Interpersonal Relationship Assessment Scale,Interpersonal Sensibility Scale extracted from Symptom Checklist 90 (SCL-90),Coping Style Scale,and Social Adaptation Scale between March and April 2015.Results The overall average scores of the students' interpersonal harassment,interpersonal sensibility,coping style,and social adaptation were 9.62±5.07,1.89±0.68,0.49±0.12,and 86.17±9.31,respectively.The score of interpersonal harassment in the male students was significantly higher than that in the female students (t=2.645,P<0.01).The score of interpersonal harassment was positively correlated to interpersonal sensibility,coping style,and social adaptation in the students significantly (r=0.549,P<0.01;r=0.253,P<0.01;r=0.113,P<0.01);the canonical correlation coefficient between interpersonal harassment and interpersonal sensibility was 0.565(P<0.001).Multivariate linear regression showed that interpersonal sensibility,coping style,and social adaptation could altogether explain 31.5% of the variance of interpersonal harassment among the students.Conclusion Some extent of interpersonal harassment exists and is influenced by interpersonal sensibility and coping style among freshmen and sophomores.
