The purpose of this study is to investigate the relations of college students among a degree of interpersonal offense, closeness with offenders and forgiveness in the universities. This study selected 1009 college students as subjects. The instruments of this study include degree of interpersonal offense scale, closeness scale and forgiveness scale. The data was analyzed by frequency distribution, t-test, one-way ANOVA, Pearson product-moment correlation and multiple regressions. The results of research are as the following：
1.70.2% of the college students have ever suffered from interpersonal offense - mainly from acquaintances and classmates, secondly, bosom friends, and thirdly, partners; in addition, bosom friends, partners, acquaintances and classmates have severest effects on them (victims) in terms of a degree of offense.
2.College students suffered from interpersonal offense tend to destroy the safety level, by contrast, do little damage to the intimacy level; speaking of the forgiveness for offenders’ behaviors, they are rarely to take revenge on the offenders, and furthermore it is more difficult for them to be confronted with offenders positively.
3.There is no difference for male or female college students in perceiving the degree of interpersonal offense and forgiving the offenders; the religious belief can make individuals perceive that the degree of interpersonal offense is lower.
4.While college students suppose they recover from hurt one day, interpersonal offense is reagrded as a lower scale and they readily forgive offenders.
5.As far as the type of offense of college students, psychological hurt accounts the greatest percentage. Further, victims with physical injuries consider that they suffered from a high degree of interpersonal offense and it is hardest for them to forgive offenders in comparisons with other victims.
6.Subjects suffered from offense which was occurred about 4 years ago (on average), 20 years ago (the farthest) and 5 months ago (the nearest). While the offense was occurred within six months and more than seven years, college students perceive the deepest degree of interpersonal offense and feel more tough to forgive offenders; on the other hand, whilst the offense was occurred between six months and 1 year and between 4 and 7 years, victims tend to forgive offenders during these two periods.
7.It is more difficult for college students to forgive offenders whereas they perceive a deeper degree of interpersonal offense as well as more alienation from offenders; a degree of interpersonal offense plays an essential role in predicting forgiveness of college students.
8.Esteem in a degree of interpersonal offense is the prediction on the presence of positive in forgiveness. In contrast, intimacy in a degree of interpersonal offense is the prediction on the absence of negative in forgiveness.
Based on the above results, in my research some related advice is proposed for the future researches, health education and counseling.
