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.
This purpose of this article is to explore differences by gender and school grade in patterns of association among social influences and tobacco use. Data from the 1999 (N = 15,038) and 2000 (N = 35,828) National Youth Tobacco Survey (American Legacy Foundation, 1999, 2000), a nationally representative, repeated cross-sectional survey, were used in the analysis. The authors compared effects on adolescent smoking. Direct paths from social environment to current smoking increased from middle school to high school. Indirect paths with social image mediating this relationship revealed a smaller increase. The pattern was constant across subsamples. Social image of smokers mediated the influence of social environment on adolescent smoking. Social image had a greater effect on smoking among middle school boys and high school girls.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
