Fifty-two non-treatment-seeking methamphetamine-using men who have sex with men were enrolled in Project Tech Support, an open-label pilot study to evaluate whether exposure to theory-based [social support theory (SST), social cognitive theory (SCT), and health belief model (HBM)] text messages could promote reductions in HIV sexual risk behaviors and/or methamphetamine use. Multivariable analyses revealed that increased relative exposure to HBM or SCT (vs. SST) text messages was associated with significant reductions in the number of HIV serodiscordant unprotected (i.e., without a condom) anal sex partners, engagement in sex for money and/or drugs, and frequency of recent methamphetamine use; additionally, increased relative exposure to HBM (vs. SCT or SST) messages was uniquely associated with reductions in the overall number of non-primary anal sex partners (all p ≤ 0.05, two-tailed). Pilot data demonstrated that text messages based on the principles of HBM and SCT reduced sentinel HIV risk and drug use behaviors in active methamphetamine users.
52名不寻求治疗的男男性行为甲基苯丙胺使用者参与了“技术支持项目”，这是一项开放标签的试点研究，旨在评估接触基于理论的（社会支持理论[SST]、社会认知理论[SCT]和健康信念模型[HBM]）短信是否能促进减少艾滋病毒性风险行为和/或甲基苯丙胺使用。多变量分析显示，与SST相比，接触HBM或SCT短信的相对增加与艾滋病毒血清学不一致的无保护（即不使用避孕套）肛交性伴侣数量、为钱和/或毒品进行性行为以及近期甲基苯丙胺使用频率的显著减少有关；此外，与SCT或SST相比，接触HBM短信的相对增加与非主要肛交性伴侣总数的减少有独特关联（所有p≤0.05，双侧）。试点数据表明，基于HBM和SCT原则的短信减少了活跃甲基苯丙胺使用者中的哨点艾滋病毒风险和药物使用行为。
