Guy2Guy (G2G)
Guy2Guy (G2G) is a 6-week HIV prevention program delivered daily via text messaging to 14-18 year old males who self-identify as gay, bisexual, and/or queer. In addition to program content, participants were paired with another participant (i.e., a Text Buddy) with whom they can text throughout the program to provide support; and an on-demand advice line, G2Genie, which shares information about condoms, sex, relationships, and the LGBT (lesbian, gay, bisexual, transgender) community.
Content is guided by the Information-Motivation-Behavioral Skills (IMB) model and focuses on: HIV information, motivations to engage in HIV preventive behavior, communication skills, behavioral skills (e.g., using a condom; HIV testing); and healthy/unhealthy relationships. Behavioral skills content was reinforced using brief online videos. The intervention is 5 weeks long. A "booster" is delivered 6-weeks post-intervention end and reviews the topics. Content is tailored by sexual experience.
|
Healthy Lifestyle Control
The attention-matched control arm message content consists of information publicly available online related to living a healthy lifestyle. Content discussed includes: STD (sexual transmitted diseases) information, nutrition and sleep hygiene, self-esteem and body image, bullying, and drugs and alcohol. The control arm is 6-weeks in length (Week 6 is a review booster) and is delivered via text messaging. Messages are didactic and not tailored to user sexual experience. Additionally, the Text Buddy and G2Genie intervention program components are not available.

Guy2Guy (G2G) is a 6-week HIV prevention program delivered daily via text messaging to 14-18 year old males who self-identify as gay, bisexual, and/or queer. In addition to program content, participants were paired with another participant (i.e., a Text Buddy) with whom they can text throughout the program to provide support; and an on-demand advice line, G2Genie, which shares information about condoms, sex, relationships, and the LGBT community.
Content is guided by the Information-Motivation-Behavioral Skills (IMB) model and focuses on: HIV information, motivations to engage in HIV preventive behavior, communication skills, behavioral skills (e.g., using a condom; HIV testing); and healthy/unhealthy relationships. Behavioral skills content was reinforced using brief online videos. The intervention is 5 weeks long. A "booster" is delivered 6-weeks post-intervention end and reviews the topics. Content is tailored based upon whether one is abstinent or sexually active.
