“…The majority of sexual assaults among college students are perpetrated not by intimate partners but by classmates, friends, acquaintances or “hook-ups” (Fisher, Cullen, and Turner, 2000; Flack et al, 2007; Littleton and Breitkopf, 2006). Intimate partners are significantly less likely than acquaintances to use drugs and alcohol as a sexual aggression tactic (Cleveland, Koss, and Lyons, 1999; Koss, Dinero, Seibel, and Cox, 1988), relying instead on the easy access afforded by the relationship, sexual precedence, and verbal persuasion to obtain sex from an unwilling partner (see Livingston, Buddie, Testa, and VanZile-Tamsen, 2004).…”
