Network Analysis of Sexual Sensation Seeking, Internalized Homophobia, and Social Norms Among Men Who Have Sex with Men with Different Sexual Partner Types

Abstract

Men who have sex with men (MSM) are at disproportionate risk for developing sexually transmitted infections (STIs) such as HIV. Understanding the relationships among factors related to risky sexual behaviors, such as internalized homophobia, sexual sensation seeking, and individual and community norms, among MSM with different sexual partner types may contribute to designing targeted interventions for reducing risky sexual behaviors and STI transmission. We conducted a cross-sectional study recruiting 781 MSM in Sichuan Province, China. All participants were divided into groups with and without sexual partners, groups with regular and casual sexual partners, and groups with only male and both male and female partners in the past 6 months. Network analysis was used to analyze the relationships among dimensions of self-reported sexual sensation seeking, internalized homophobia, and social norms in different groups. Of 781 MSM, 606 (77.6%) had sexual partners in the past 6 months, and among these participants, 429 (70.8%) had casual sexual partners, and 103 (17.0%) had both male and female sexual partners. The complex and intensive relationships between dimensions were mainly observed in networks of MSM with any type of sexual partners, with individual norms (dimension of social norms) presenting strongly negative relationships with fresh feeling (dimension of sexual sensation seeking) and homosexuality morality (dimension of internalized homophobia). One dimension of sexual sensation seeking (i.e., fresh feeling) and two dimensions of internalized homophobia (i.e., homosexuality morality and self-identification) were relatively central variables in most groups, especially for those with casual sexual partners. Our study highlights the role of individual norms in restraining sensation seeking, internalized homophobia, especially among MSM with sexual partners. Intervention targeting these central variables may contribute to reduced risky sexual behaviors and further slow the spread of STIs in MSM.
