Teenage drinking is a topic of much concern, with risky sexual behavior among the more immediate risks of personal harm (CASA, 1999). During adolescence, alcohol use and misuse is associated with early sexual onset (Bailey, Pollock, Martin, & Lynch, 1999; Kinsman, Romer, Furstenburg, & Schwarz, 1998; Kowaleski-Jones & Mott, 1998; Lammers, Ireland, Resnick, & Blum, 2000; Mott & Haurin, 1988; Small & Luster, 1994), greater frequency of sexual intercourse (Poulin & Graham, 2001), and history of multiple sexual partners (Bailey et al., 1999; Howard & Wang, 2004; Lowry, Holtzman, Truman, Kann, Collinsm, & Kolbe, 1994; Santelli, Brener, Lowry, Bhatt, & Zabin, 1998). In many studies (but not all, c.f., CASA, 1999), inconsistent or ineffective use of contraception is also reported (Fergusson & Lynskey, 1996; Fortenberry, Costa, Jessor, & Donovan, 1997; Hingson, Strunin, Berlin, & Heeren, 1990) and these behaviors together increase risk for sexually transmitted infection (STI), unplanned pregnancy, and early childbearing (Kirby, 2002; Manlove, Terry, Gitelson, Papillo, & Russell, 2000).
