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.

Outcome Measures

Primary Outcomes (2)

  • The Number of Condomless Sex Acts at 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.

    3-months post-intervention

  • Percent of Boys Reporting Abstinence at 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.

Study Arms (2)

Guy2Guy (G2G)

EXPERIMENTAL

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.

Behavioral: Guy2Guy (G2G)

Healthy Lifestyle Control

NO INTERVENTION

The attention-matched control arm message content consists of information publicly available online related to living a healthy lifestyle. Content discussed includes: STD 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.

Interventions

Guy2Guy (G2G)BEHAVIORAL

G2G is a text messaging-based healthy sexuality and HIV prevention program specifically for 14-18 year old GBQ adolescent males. 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 is reinforced using brief online videos. The intervention is 5 weeks long. A "booster" is delivered 6-weeks post-intervention end and reviews the topics covered in the intervention. G2G content is tailored based upon whether one is abstinent or sexually active.

Limitations and Caveats

All data were collected via self-report questionnaires, so may be affected by recall and social desirability bias. The sample may not be representative of gay and bisexual youth who use the Internet less frequently or are not 'out' on social media.
