Perceived competencies, peer group affiliation, and risk behavior among early adolescents.

This study examined the role of self-esteem and peer group membership in risk behavior among 183 8th graders in a multiethnic school. The hypothesis was that domain-specific rather than global self-esteem would be associated with "crowd" membership that in turn would be related to risk behavior. Data were gathered through informant interviews and individual surveys. Domain-specific self-esteem was related to crowd affiliation as well as to alcohol and cigarette use; global self-esteem was not related. Crowd affiliation related to alcohol use and sexual behavior after controlling for the effects of demographic and self-esteem variables, but crowd membership did not fully mediate the relationship between self-esteem and risk behavior. Availability of alcohol and cigarettes mediated the relationship between crowd affiliation and use of these substances. Findings support growing evidence that multiple adolescent peer groups exist and that group membership is closely tied to behavior.
