- Brief Summary
The purpose of this study is to examine whether Guy2Guy (G2G), a text messaging-based healthy sexuality and human immunodeficiency virus (HIV) prevention program intervention for 14-18 year gay, bisexual and queer men, is associated with HIV preventive behavior (e.g., condom use) compared to an attention-matched control group.
- Detailed Description
Adolescent men who have sex with men (AMSM) are disproportionately affected by HIV. They account for almost 70% of HIV diagnoses among all young people and are the only risk group with an increasing number of HIV/AIDS diagnoses. Despite this disproportionate burden, current HIV prevention programs focus primarily on adults and heterosexual youth. As such, there is an urgent need for evidence-based HIV prevention programs targeting AMSM. Because issues affecting sexual health decisions among AMSM are unique, intervention programs cannot be translated from heterosexually focused interventions. Instead, they need to be designed from the ground up to ensure appropriately tailored content that resonates with the target population. Evidence-based HIV prevention programs targeting AMSM are urgently needed.
The Guy2Guy (G2G) intervention is a text messaging-based HIV prevention program designed for the specific needs of adolescent males who self-identify as gay, bisexual, or queer (GBQ) and are between the ages of 14-18 years. The intervention will be tested in a randomized controlled trial against an attention-matched control group which receives text messages about healthy lifestyle (e.g., exercise, nutrition). A total of 300 GBQ adolescent males will be into the study using an online recruitment strategy. The study is being conducted by researchers at the Center for Innovative Public Health Research and Northwestern University.
The primary efficacy outcome measures are unprotected sex acts and abstinence at 3-months follow-up. The investigators hypothesize that those in the G2G intervention will be significantly more likely to be engage in HIV preventive behavior (e.g., use condoms when having vaginal/anal sex) at 3-months follow-up compared to the attention-matched control group. Secondary efficacy outcomes include unprotected sex acts and abstinence at 3-month follow-up by sexual experience groups (i.e., ever had sex versus never had sex at baseline), HIV testing rates, and unprotected sex acts and abstinence at intervention end (5 weeks post enrollment) for those in the intervention versus control groups; and for participants who were sexually experienced and inexperienced at baseline, separately.
If effective, G2G has promise to be quickly and cost-effectively implemented to scale to help to curb the spread of HIV infection among AMSM long into adulthood.

Group Intervention Description Guy2Guy (G2G) Guy2Guy (G2G) 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 are 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 lesbian, gay, bisexual, transgender (LGBT) community.
- Primary Outcome Measures
Name Time Method Percent of Boys Reporting Abstinence at 3-months Post-intervention 3-months post-intervention At 3 months post intervention participants were asked whether or not they had had vaginal and anal sex in the past 90 days. Those who said no to both were coded as abstinent. The relative difference of abstinence (neither engaging in anal nor vaginal sex) was examined in the intervention versus control group.
The Number of Condomless Sex Acts at 3-months Post-intervention 3-months post-intervention The relative difference of unprotected anal and/or vaginal sex acts in the intervention versus control group at 3-months post-intervention. The count was truncated at 10 or higher to correct for over-dispersion.
- Secondary Outcome Measures
Name Time Method Percent of Boys Reporting Abstinence at 5 Weeks Post-enrollment Intervention-end (5 weeks post-randomization) The relative difference of abstinence (neither engaging in anal nor vaginal sex) in the intervention versus control group at intervention end (5 weeks post enrollment).
Number of Unprotected Sex Acts Among Sexually Experienced Boys at 5 Weeks Post-enrollment Intervention end (5-weeks post enrollment) The relative difference of unprotected anal and/or vaginal sex acts in the intervention versus control group intervention end (5 weeks post enrollment) among youth who have ever had sex at baseline
Percent of Boys Reporting Abstinence Among Sexually Experienced at 5 Weeks Post-enrollment Intervention end (5-weeks post enrollment) At 5 weeks post-enrollment, participants were asked whether or not they had had vaginal and anal sex since the beginning of the program. Those who said no to both were coded as abstinent. The relative difference of abstinence (neither engaging in anal nor vaginal sex) was examined among youth who have ever had sex at baseline in the intervention versus control groups.
Number of Unprotected Sex Acts Among Sexually Experienced at 3-months Post-intervention 3-months post-intervention The relative difference of unprotected anal and/or vaginal sex acts in the intervention versus control group at 3-months post-intervention among youth who have ever had sex at baseline
Number of Unprotected Sex Acts Among Sexually Inexperienced at 3-months Post-intervention 3-months post-intervention The relative difference of unprotected anal and/or vaginal sex acts in the intervention versus control group at 3-months post-intervention among youth who have never had sex at baseline
Percent of Boys Reporting Abstinence Among Sexually Experienced at 3-months Post-intervention 3-months post-intervention At 3 months post intervention participants were asked whether or not they had had vaginal and anal sex in the past 90 days. Those who said no to both were coded as abstinent. The relative difference of abstinence (neither engaging in anal nor vaginal sex) was examined among youth who have ever had sex at baseline in the intervention versus control groups.
Percent of Boys Reporting Abstinence Among Sexually Inexperienced at 3-months Post-intervention 3-months post-intervention At 3 months post intervention participants were asked whether or not they had had vaginal and anal sex in the past 90 days. Those who said no to both were coded as abstinent. The relative difference of abstinence (neither engaging in anal nor vaginal sex) was examined among youth who have never had sex at baseline in the intervention versus control groups.
Percent of Sexually Active Boys Reporting an HIV Test in the Past 3 Months at 3-months Post-intervention 3-months post-intervention The relative difference of HIV testing over the past 3 months in the intervention versus control group at 3-months post-intervention among those who had ever vaginal or anal sex with a penis at baseline
Number of Condomless Sex Acts at 5 Weeks Post-enrollment Intervention end (5-weeks post enrollment) Relative difference of unprotected sex acts at intervention end (5 weeks post enrollment) for those in the intervention versus control groups
Number of Unprotected Sex Acts Among Sexually Inexperienced Boys at 5 Weeks Post-enrollment Intervention end (5-weeks post enrollment) The relative difference of unprotected anal and/or vaginal sex acts in the intervention versus control group at at intervention end (5 weeks post enrollment) among youth who have never had sex at baseline
Percent of Boys Reporting Abstinence Among Sexually Inexperienced at 5 Weeks Post-enrollment Intervention end (5 weeks post enrollment) At 5 weeks post-enrollment, participants were asked whether or not they had had vaginal and anal sex since the beginning of the program.
