Alcohol-related problems have been frequently identified as an important risk factor for early sexual activity (Carroll & Carroll, 1995; Fergusson & Lynskey, 1996; Graves & Leigh, 1995; Iacono & McGue, 2002; Mott, Fondel, Hu, Kowaleski-Jon, & Menaghan, 1996; Poulson, Eppler, Satterwhite, Wuensch, & Bass, 1998). Nearly 20% of youth report drinking alcohol the first time they had sexual intercourse (Cooper, Peirce, & Huselid, 1994), and approximately 25% of sexually active youth consumed alcohol or drugs the most recent the time they had sexual intercourse (Centers for Disease Control and Prevention, 2002). Past findings also link conduct disorder and substance use disorders with elevated rates of sexual intercourse that is unprotected or performed in exchange for money or drugs (Booth & Zhang, 1997; Mezzich et al., 1997; Whitmore, Mikulich, Ehlers, & Crowley, 2000).
