A total of 140 first-semester college students (109 females, 31 males) completed an anonymous survey early in their first semester; the survey assessed 18 potential predictors of hooking up that were identified from theory and past research. At the end of their first semester, students again responded to a survey and provided data on their oral and vaginal sex hookup behavior (occurrence and number of partners), distress, and self-esteem. Baseline and follow-up data were linked using unique codes that protected participants' anonymity. Pre-college hookup patterns, peak intoxication level, and situational triggers for hookups were consistent predictors of oral and vaginal sex hookup behavior (and number of hookup partners) in the first semester of college. Penetrative sex hookups increased psychological distress for females, but not for males. Implications for education and intervention as well as suggestions for future research are discussed.

Any romantic/sexual coupling can generate feelings of hurt and regret, but a study at Syracuse University suggests that, far from feeling victimized, women who hook up are typically assertive actors. The researchers (Fielder & Carey, 2010) asked 118 women undergraduates why they’d hooked up:

I wanted to have sex: 80%

It was an impulsive decision: 58%

I felt attracted to the guy: 56%

I was drunk: 51%

The guy really wanted it: 33%

I wanted to feel desirable: 29%

(Respondents could cite more than one reason.)

Do Hook-Ups exploit women?

Why do you think penetrative sex hookups increased psychological distress for females, but not for males?
