Two samples of 6th to 12th graders from separate communities were given measures of peer conformity dispositions (willingness to accede to peer pressure), perceptions of peer pressure, and selfreported frequency of behavior concerning two major aspects of teenage life: peer involvement (degree of socializing with friends) and misconduct (drug/alcohol use, sexual intercourse, and minor delinquent behavior). Respondents perceived less peer pressure toward misconduct than peer involvement and also were comparatively less willing to follow peers in misconduct. Nevertheless, perceived peer pressure and conformity disposition accounted for more of the variance in self-reported misconduct than in self-reported peer involvement. Age differences were modest and varied among measures and samples. The samples also differed in the magnitude of perceived pressures and conformity dispositions as well as in the degree to which these variables were associated with self-reported behavior. The findings reveal a complexity in adolescent conformity that bears elaboration in future research.

Many researchers have speculated about the role peer groups play in adolescent development, but few have examined teenagers' own perspective on the importance of group affiliations. The two studies reported here, involving 1,300 7th to 12th graders in three Midwestern U.S. communities, assessed teenagers' valuation of belonging to a “crowd” as well as the reasons they cited to support or oppose crowd affiliation. The importance of crowd affiliation declined across age. Younger adolescents generally favored membership, emphasizing the crowd's ability to provide emotional or instrumental support, foster friendships and facilitate social interaction. Older respondents expressed dissatisfaction with the conformity demands of crowds and felt their established friendship networks obviated the need for peer group ties. The importance of crowd affiliation was not related to the strength of respondents' sense of identity but did vary significantly with their willingness to conform to peers and the centrality of their position in peer groups or the type of crowd to which they belonged. Findings emphasized that adolescent peer groups can serve multiple functions, whose salience shifts with age.
