The influence of peers and peer norms is a significant health determinant of adolescent sexual activity, yet little is known in health education about differences between peer pressure and friend pressure on adolescents. The objective of this study was to investigate differences between social norms among friends and social norms among peers and determine if differences influence adolescents’ sexual risk perceptions. As a secondary data analysis of the 2006 Adolescent Health Risk Behaviors Survey data, this study included 915 adolescents in grades 8, 10, and 12 who completed questions pertaining to perceived sexual activity rates and perceived risks from having unprotected sex. T-tests, analyses of variance, and linear regression analyses indicated that adolescents perceived a difference between social norms among peers and social norms among friends and that these differences influenced risk perceptions differently. Future research should explore how social norms among friends influence adolescents’ risk behaviors and how to incorporate this focus into effective and efficient sex education efforts.
