The Influence of Peer Groups on Sexual Behavior among Tenth-Grade Students

Abstract

Adolescence is a transitional period characterized by biological, cognitive, and social changes. During this phase, peer groups exert strong influence, often shaping values, attitudes, and behaviors including those related to sexuality. This study aimed to analyze the effect of peer group involvement on the sexual behavior of tenth-grade students. A quantitative analytic design with a cross-sectional approach was employed. A total of 30 students were selected through accidental sampling. Data were analyzed using paired sample t-tests to examine differences in sexual behavior between students actively involved in peer groups and those who were not. Findings indicated that 70% of students who participated in peer groups engaged in sexual behaviors such as kissing, petting, and physical intimacy, compared to 40% of students not in peer groups. Statistical analysis revealed a significant effect of peer group membership on adolescent sexual behavior (p = 0.000, < 0.05). Peer groups significantly affect the sexual behavior of adolescents. Strengthening reproductive health education and parent–adolescent communication is critical to prevent risky sexual practices. Schools should integrate extracurricular activities and peer education programs that promote healthy relationships and responsible sexual decision-making.
