Past research reporting a relationship between parent-child communication about sex and similarity in sexual attitudes between late adolescents and their parents studied late adolescents who were still residing with their parents. The present study attempted to determine whether this relationship was present in college students who were living away from home. Ohio State University main and regional campus students (N=355) and their parents completed questionnaires which measured sexual attitudes, sexual knowledge, sexual behavior, and amount of family communication about sex. Regardless of whether they lived at home or not, and regardless of which campus they attended, the students in this study exhibited the same pattern of attitude similarity that had been found in the past. Students in high communication families had attitudes which were more similar to those of their parents than did the students in the low communication group, regardless of proximity to parents or campus attended. While this study supports the view that parent-child communication about sex is related to adolescents' sexual values, it does not lend much support to the idea that family decisions about sexuality result in less adolescent sexual activity or in a greater use of effective contraception.
