Abstract
There is a paucity of literature documenting how the constructs of the Information–MotivationBehavioral Skills (IMB) model are aected by exposure to technology-based HIV prevention programs. Guy2Guy, based on the IMB model, is the rst comprehensive HIV prevention program delivered via text messaging and tested nationally among sexual minority adolescent males. Between June and November 2014, 302 14–18year old gay, bisexual, and/or queer cisgender males were recruited across the US on Facebook and enrolled in a randomized controlled triatesting Guy2Guy versus an attentionmatched control program. Among sexually inexperienced youth, those in the intervention were more than three times as likely to be in the Higmotivationgroup at follow-up as control youth (aOR = 3.13; P value = 0.04). The intervention eect was not signicant when examined separately for those who were sexually active. HIV information did not signicantly vary by experimental arm at 3months 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 reected 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.
