Using a longitudinal cluster-randomized controlled design, we examined whether the effects of Competencies for Adolescents with a Healthy Sexuality (COMPAS), an evidence-based sexual health promotion intervention, differ by adolescents' sexual experience. Participants were 699 students aged 14-16, 45.9% were sexually experienced, and assessed in the baseline, posttest, and 12- and 24-month follow-ups. All were recruited from 10 schools that were randomly assigned to the COMPAS program and waiting-list groups (WLG). Using an intent-to-treat analyses, longitudinal changes in psychosocial and behavioral outcomes were explored using generalized estimating equations. Compared to the WLG, COMPAS had a positive impact on six of the seven psychological and behavioral outcomes. Non-sexually experienced reported more favorable HIV-related attitudes, higher condom use intention, lower number of sexual partners, and higher condom use than those sexually experienced. Findings support the importance of implementing sex education actions before adolescents get involved in their first intimate relationships in order to achieve greater impact.
采用纵向聚类随机对照设计，我们考察了基于证据的促进青少年性健康的干预措施——青少年健康性行为能力（COMPAS）是否会因青少年的性经验而产生不同的效果。参与者为 699 名年龄在 14-16 岁的学生，其中 45.9%有过性经验，并在基线、后测以及 12 个月和 24 个月的随访中进行评估。所有参与者均来自 10 所学校，这些学校被随机分配到 COMPAS 项目组和等待名单组（WLG）。采用意向性治疗分析，使用广义估计方程探讨了心理和行为结果的纵向变化。与 WLG 相比，COMPAS 对七个心理和行为结果中的六个产生了积极影响。无性经验者报告称，与有性经验者相比，他们对 HIV 的态度更积极，使用避孕套的意愿更高，性伴侣的数量更少，使用避孕套的频率更高。研究结果支持在青少年开始第一次亲密关系之前实施性教育行动的重要性，以便取得更大的效果。
