There is a paucity of literature documenting how the constructs of the Information-Motivation-Behavioral Skills (IMB) model are affected by exposure to technology-based HIV prevention programs. Guy2Guy, based on the IMB model, is the first comprehensive HIV prevention program delivered via text messaging and tested nationally among sexual minority adolescent males. Between June and November 2014, 302 14-18 year old gay, bisexual, and/or queer cisgender males were recruited across the US on Facebook and enrolled in a randomized controlled trial testing Guy2Guy versus an attention-matched control program. Among sexually inexperienced youth, those in the intervention were more than three times as likely to be in the "High motivation" group at follow-up as control youth (aOR = 3.13; P value = 0.04). The intervention effect was not significant when examined separately for those who were sexually active. HIV information did not significantly vary by experimental arm at 3 months post-intervention end, nor did behavioral skills for condom use or abstinence vary. The increase in motivation to engage in HIV preventive behavior for adolescent males with no prior sexual experience is promising, highlighting the need to tailor HIV prevention according to past sexual experience. The behavioral skills that were measured may not have reflected those most emphasized in the content (e.g., how to use lubrication to reduce risk and increase pleasure), which may explain the lack of detected intervention impact.

目的:本研究旨在探讨信息-动机-行为技能(IMB)模型的结构如何受到基于技术的 HIV 预防项目的影响。 Guy2Guy 是首个基于 IMB 模型的综合性 HIV 预防方案,通过短信向性少数青少年男性提供,并在全国范围内进行了测试。
方法:2014 年 6 月至 11 月,美国通过 Facebook 招募了 302 名 14-18 岁的男同性恋、双性恋和/或顺性别男青年,他们参与了一项随机对照试验,比较了 Guy2Guy 与注意力匹配的对照组。
结果:在无性行为经验的青年中,干预组在随访时处于“高动机”组的可能性是对照组的三倍以上(aOR=3.13;P 值=0.04)。对于有性行为的青年,干预效果不显著。干预结束后 3 个月,HIV 知识在实验组间没有显著差异,性行为技能( condom 使用和禁欲)也没有显著差异。
结论:对于没有性行为经验的青少年男性,参与 HIV 预防行为的动机增加是有希望的,这突出表明需要根据过去的性行为经验来调整 HIV 预防措施。测量的行为技能可能没有反映出方案内容中最强调的技能(例如,如何使用润滑剂来降低风险和增加快感),这可能解释了干预效果未被检测到的原因。
