It made use of the 203 fraternity and sorority members of the 11 recognized fraternities/sororities in the University of Northern Philippines, Vigan City, Ilocos Sur. The study made use of the descriptive-correlational method of research. The profile of the respondents in terms of fraternity/sorority affiliation, course, age, and sex was correlated with their antisocial personality. Based on the findings of the study, the age of the respondents is a significant factor that influenced their antisocial personality along social capacity and their overall antisocial personality. The overall antisocial personality of the respondents is average, while the social involvement and social responsibility dimensions were low. The social capacity and social relations of the respondents, on the other hand, is average. As a result of the study, topics on fraternity/sorority operations should be included in the orientation program of the Office of Student Affairs to expose the students about the existence and operation of fraternities/sororities in the university; the same office should conduct regular activities like sports and cultural competitions where the fraternity/sorority members can take part in order to eliminate their antisocial personality; it should set a menu of activities from which the fraternities/sororities can choose to implement on the basis of their capacity; and it should be ready to provide all the necessary assistance needed by the fraternities.
