Changes in Adolescent Heterosexual Behaviors from the 1980s to the Present in Various Western Countries: A Systematic Review

Abstract

Adolescence is a stage of significant intrapersonal and interpersonal changes, influenced by cultural and historical shifts. This study aims to analyze the changes in heterosexual behaviors among adolescents in Western countries over the past 50 years approximately. For this purpose, we conducted a systematic review following the PRISMA model, utilizing the online databases EBSCO, WoS, and Scopus, covering the period from 1980 to 2024, across ten European countries. The review focused on studies published in scientific journals with regional or national samples. In addition to the 30 selected studies, three more were included due to their relevance as cited in the selected articles. Despite the considerable methodological heterogeneity, the results showed a relative stabilization of the differences in sexual behaviors of boys and girls throughout time. Those differences were more evident in Southern European countries. Some changes were also noted, such as the delay in the initiation of the first sexual intercourse, a trend observed over the last decade. The findings are discussed in terms of the sexual script theory, highlighting the importance of these mental frameworks in the heteronormative sexual socialization of boys and girls. Future research should emphasize the diversity of heterosexual behaviors, their significance, and the emotional experiences that accompany them.
