Special Issue Information

Dear Colleagues,

Adolescence and young adulthood are critical developmental stages marked by profound physical, emotional, and social changes. During this period, individuals begin to explore their identities, form intimate relationships, and engage in sexual behaviours that may have significant and lasting implications for their health and well-being. The intersection between sexual behaviour and health outcomes—including mental health, sexual and reproductive health, and social development—has become an increasingly important area of study in public health and the behavioural sciences.

This Special Issue aims to advance interdisciplinary knowledge on sexual behaviour and its health-related consequences among adolescents and young adults. We welcome original research, systematic reviews, and theoretical contributions that examine topics such as sexual initiation, contraception use, STI prevention, gender identity, sexual orientation, consent, digital sexual behaviours, and the role of education and policy. We also encourage submissions that consider the impact of social determinants of health, cultural contexts, and intersectionality.

By fostering a multidimensional and global perspective, this Special Issue seeks to promote evidence-based strategies and inclusive policies that support safe, informed, and healthy sexual development. Contributions from diverse disciplines and geographical contexts are especially welcome to deepen our understanding and inform future research, practice, and advocacy.

Introduction: Women and LGBTQ+ undergraduates face higher rates of sexual assault and rape compared to cisgender male peers—the overwhelming majority of perpetrators. Federal policies have aimed to curb campus sexual violence, yet questions remain about the efficacy of consent education, particularly among cisgender heterosexual men. Methods: This study surveyed 1567 undergraduate students at a large Northeastern public university in 2017 and 2022. Responses to a nine-item consent scale were analyzed by gender, sexuality, and demographic factors. Results: Cisgender heterosexual (cis-het) men had poorer understanding of consent compared to women and LGBTQ+ students, both in 2017 and 2022. Cis-het men’s consent scores showed no improvement, and for some items worsened from 2017 to 2022, while other groups showed significant improvements in recognizing the nuances of consent. Conclusions: Findings suggest that, despite increased focus on sexual assault prevention and social awareness campaigns like #MeToo, cisgender heterosexual men’s understanding of consent has not improved, highlighting the persistent challenge in shifting deeply ingrained beliefs about consent. Educational efforts should address these beliefs more directly, focusing on transforming societal norms around masculinity and sexual entitlement. Policy Implications: These results underscore the need for more comprehensive, gender-transformative education on consent. Current programs primarily focus on victims rather than perpetrators, which fails to address the root causes of sexual violence. To reduce sexual assault, consent education, delivered K-12 and in higher education, must consistently challenge harmful gender norms and promote equitable relationships. More targeted strategies are necessary to engage cisgender heterosexual men in these discussions. Full article
