Although much has been written concerning the sexual harassment of university students, no research has yet directly examined the behaviors of university professors themselves. The present study describes the responses of 235 male faculty members of a prestigious, research-oriented university who responded to a survey inquiring about social and sexual interaction among faculty and students. Although the majority of the responses focused on mentoring and social interactions, a sizable minority (26%) reported sexual involvement with women students. In addition to item frequencies, a structural analysis of the phenomenon of academic harassment is presented, and discussed in the context of the subjects' responses to an open-ended invitation to comment on the study.
