Comprehensive sexuality education for fraternity-affiliated undergraduates: a pilot program to improve sexual and reproductive health knowledge, attitudes, and communication.

: Comprehensive sexuality education (CSE) allows for informed and healthy decisions. College students often lack understanding of sexual and reproductive health (SRH). Conversations and Pizza (CAP), an interactive curriculum, was designed to address gaps in CSE and improve SRH outcomes. 66 fraternity affiliated undergraduate students. A six-session intervention discussed gender norms, biology, consent, harassment, and bystander intervention. Pre- and post-quantitative surveys assessed attitudes and behaviors; plus-delta format was used for qualitative feedback. Qualitative data reflected engagement. Post-intervention, multiple measures improved (McNemar p < 0.05): perceived self-efficacy in consent and peer norms (4/8 measures), bystander intervention (5/6), and awareness of harassment (2/5). Participants reported more conversations with partners (pregnancy and STI prevention, 50% to 75%); human papillomavirus (HPV) vaccination receipt increased (60% to 93%, McNemar p < 0.001). Reproductive health outcomes improved in this pilot, laying the groundwork for continued testing. CAP is a successful pilot program that can be evaluated for a variety of groups and formats.
