Differences in motives for condom use and their implications for understanding frequency of use were investigated in a random, biracial (Black, White) sample of heterosexuals, aged 17 to 25 years (n = 902). Results indicated that sexually active young adults-regardless of race, age, gender, or relationship status-were more likely to use condoms to prevent pregnancy than to prevent disease. Reasons for use mediated the effects of relationship status on condom use per se and moderated the effects of attitudinal and perceptual variables on condom use. Finally, comparisons among condom users motivated by different prevention goals and nonusers (n = 388) revealed that differences among user subgroups were nearly as numerous and, in some cases, more robust than differences between users and nonusers. These findings indicate that condom users comprise distinct subgroups, defined in part by their underlying motives for use, and highlight important conceptual and empirical reasons to distinguish among them.

The implications of a functionalist perspective for understanding sexual risk taking are explored. Key motivational dimensions thought to underlie human behavior (viz., approach vs. avoidance, autonomy vs. relatedness) were used to identify 4 broad domains of sexual motivations and to develop a measure of specific motives within each of these domains. Data from both college student and community samples are used to demonstrate the psychometric adequacy of these scales and to show that having sex for different reasons predicts distinctive patterns of sexual risk taking both cross-sectionally and longitudinally: that selection into specific types of sexual relationships partially mediates these effects; and that these needs may be differentially expressed, or even suppressed, depending on relationship context. Results provide strong support for the functionalist perspective on behavior and indicate that an adequate understanding of sexual risk-taking behavior must take into account the various needs and goals that such behavior can serve.
