We describe the sexual risk behaviors, psychological distress, and substance use of 102 late adolescent girls and identify predictors of protected and unprotected vaginal sex. Participants completed questionnaires assessing hypothesized predictors and then daily behavioral diaries for 12 weeks. Protected intercourse was predicted by baseline sexual behavior, greater knowledge, positive condom attitudes, lower perceived condom-use difficulty, greater condom-use intentions, more drinking days, less binge drinking, less Ecstasy use, and lower psychological distress. Unprotected intercourse was predicted by baseline sexual behavior, binge drinking, Ecstasy and opiate use, fewer drinking days, and fewer daily drinks. These findings suggest that psychological distress, substance use, and sexual risk behavior are interconnected and should be considered collectively in interventions for adolescent females.

(2006) examined the relationship between patterns of risk behaviors (i.e., smoking, sex, drug, and alcohol use) and depressive symptoms. Overall, girls experienced more depressive symptoms than boys, and every risk behavior was related to increased depressive symptoms. Although their study was limited by its cross-sectional design, it provides evidence of the prominent nature of depressive symptoms in a nationally representative sample of adolescent girls.

NIH Public AccessThe clustering of sexual and substance use behaviors was also observed in a recent study of clients attending an STD clinic (50% female); in this sample of patients with documented sexual risk behaviors, one-third of the females were also classified as having a substance use disorder (Cook et al., 2006). Other investigators have reported a significant association between substance use and risky sex in teens as young as 12-15 years (Bachanas et al., 2002). The co-occurrence of substance use and risky sex has not been found universally, however; for example, drinking before sex was not related to unprotected sex in girls attending an STD clinic (Fortenberry, Orr, Katz, Brizendine, & Blythe, 1997) nor in college students (deVisser & Smith, 2001).In summary, psychological distress and depressive symptoms, substance use, and sexual health are often intertwined in girls from early to late adolescence and their interconnectedness needs to be clarified. To reduce the incidence of HIV in adolescent girls, health educators and other interventionists must develop effective, theoretically-driven gender-tailored interventions that target the determinants of sexual risk behavior (Fishbein, 2000).
