The current study was designed to gain a better understanding of the nature of the relationship between substance use and sexual risk taking within a community sample of women (N = 1,004). Using confirmatory factor analysis, the authors examined the factor structure of sexual risk behaviors and substance use to determine whether they are best conceptualized as domains underlying a single, higher order, risk-taking propensity. A 2 higher order factor model (sexual risk behavior and substance use) provided the best fit to the data, suggesting that these 2 general risk domains are correlated but independent factors. Sensation seeking had large general direct effects on the 2 risk domains and large indirect effects on the 4 first-order factors and the individual indicators. Negative affect had smaller, yet still significant, effects. Impulsivity and anxiety were unrelated to sexual health risk domains.
Keywordssexual risk taking; alcohol drinking patterns; drug usage; sensation seeking; negative affect Numerous studies have shown that high levels of substance use and risky sexual behaviorssuch as drinking in conjunction with sex, and sex with a casual and/or a risky partner-are associated with each other (Cooper, 2002;Guo et al, 2002). In addition, both health-risk domains are associated with negative sexual outcomes, including sexually transmitted infections (STIs; Corbin & Fromme, 2002) and sexual assault (Kilpatrick, Acierno, Resnick, Saunders, & Best, 1997). Although the empirical relationship is well documented, the nature of the association is less well understood. The purpose of the current article is to identify the factor structure of measures of risky sexual behavior and substance use in women and to examine personality characteristics associated with these behaviors.Early studies, including male and female adolescents and adults, have revealed that the variance among measures of risky behaviors can be adequately explained by a single first-order factor, labeled "unconventionality" (e.g., Donovan & Jessor, 1985 (Fromme, Katz, & Rivet, 1997).In the current study, using multiple indicators of risk domains, we first wanted to determine whether sexual risk and substance use would be best represented by two first-order domains (Cooper et al., 2003;McGee & Newcomb, 1992) or as three first-order domains, with alcohol and drug use being distinct (Fromme et al., 1997). After the first-order domains were identified, we then wanted to confirm that a single higher order factor (health risk taking) would account for the variance among them (Cooper et al., 2003;McGee & Newcomb, 1992). In addition, because many researchers have used drinking and/or drug use concurrent with sexual intercourse as a risk marker for STI (see, e.g., Cooper, 2002), we included measures of alcohol and drug use with sex to determine whether they are best used as indicators of sexual risk taking, substance use, or both.Because personality characteristics are likely to influence women's risk-taking behavior (Cooper et al., 2003), we exami...
