A longitudinal study of heterosexual relationships, aggression, and sexual harassment during the transition from primary school through middle school

The period of early adolescence witnesses the onset of interest in heterosexual relationships. Prior to this period, youngsters spend much of their free time with same-sex peers. In the present longitudinal, multimethod study, two dimensions of heterosexual relationships were examined: cross-sex interaction and cross-sex aggression. We examined the extent to which youngsters interacted with peers of the opposite sex, as well as self-reported dating frequency. Cross-sex aggression was also examined. It was predicted that cross-sex interactions would increase with time and that youngsters would use playful strategies to initiate cross-sex interactions. Aggression was measured through self-report, direct observations, and adult completed checklists. It was predicted that both boys and girls would target opposite-sex peer for aggression. Lastly, a mediational model of sexual harassment was proposed whereby dating frequency in the middle of sixth grade would mediate the relation between bullying at the start of seventh grade and sexual harassment at the end of seventh grade. A sample of rural sixth and seventh grade students was studied across their first 2 years of middle school. Predictions were, for the most part, supported. Results are discussed in terms of the role of activity settings as specifying peer youngsters' interactions. (C) 2001 Elsevier Science Inc. All rights reserved.
