摘要
目的：本研究评价2GETHER关系教育和艾滋病预防项目对年轻男性伴侣降低艾滋病风险的效果。方法：我们进行了一个随机对照试验2GETHER相对于一个注意匹配和高度活跃的积极影响增强计划的夫妇。我们从2017年到2021年将128对年轻男性夫妇（N = 256）随机分为2GETHER组或对照组。在基线和12个月时测量主要生物医学结果（即直肠衣原体和淋病），在12个月的随访中每3个月测量一次自我报告的无安全套肛交。次要结果是其他艾滋病毒预防和危险行为、关系功能和药物使用。我们在MPlus中使用多层模型来解释二元聚类和随时间变化的个人内部变化。时间的影响（对于自我报告的结果）使用夫妇间水平的潜在增长曲线进行建模。结果：我们观察到不同情况下的结果没有差异，但12个月内的结果有显著变化。在这两种情况下，直肠性传播感染和自我报告的无避孕套肛交的发生率都显著下降。我们还观察到，在12个月的时间里，两种情况下的艾滋病毒检测显著增加，关系沟通改善，酒精相关问题减少。结论：参与2GETHER和积极情感增强计划的夫妇在HIV风险的生物医学和行为指标上都有所改善，在关系沟通方面也有所改善，但没有治疗效果，我们不能断定干预是否有改善。以夫妻为基础的促进联系的项目，包括关系教育和积极影响增强，具有降低年轻夫妇感染艾滋病毒风险的巨大潜力。（PsycInfo Database Record (c) 2025 APA，版权所有）。
Randomized controlled trial of a relationship education and HIV prevention program for young male couples: Biomedical and behavioral outcomes.
Objective: This study evaluated the efficacy of the 2GETHER relationship education and HIV prevention program for young male couples in reducing the risk for HIV.
Method: We conducted a randomized controlled trial of 2GETHER relative to an attention-matched and highly active positive affect enhancement program for couples. We randomized 128 young male couples (N = 256) to 2GETHER or control from 2017 to 2021. Primary biomedical outcome (i.e., rectal chlamydia and gonorrhea) was measured at baseline and 12 months and self-reported condomless anal sex was measured every 3 months across 12-month follow-up. Secondary outcomes were other HIV prevention and risk behaviors, relationship functioning, and substance use. We used multilevel models in MPlus to account for clustering with dyads and within-person change over time. Effects of time (for self-reported outcomes) were modeled using latent growth curves at the between-couple level.
Results: We observed no differences between conditions in outcomes, but there was a significant change in outcomes across 12 months. Rates of rectal sexually transmitted infections and self-reported condomless anal sex decreased significantly in both conditions. We also observed significant increases in HIV testing, improvement in relationship communication, and reduction in alcohol-related problems in both conditions across 12 months.
Conclusion: Couples in both the 2GETHER and positive affect enhancement programs showed improvement in biomedical and behavioral indicators of HIV risk, as well as improvement in relationship communication, but without a treatment effect we cannot conclude improvement resulted from the interventions. Couple-based programs that promote connectedness, including relationship education and positive affect enhancement, have a strong potential to reduce young couples' HIV risk.
