Brief summary

The proposed MyPEEPS Mobile intervention is a novel and evidence-driven intervention using mobile technology to deliver HIV prevention information specifically developed for at-risk young men who have sex with men (YMSM). This will be the one of the first studies to test the efficacy of a scaled-up, mobile version of an existing human immunodeficiency virus (HIV) prevention intervention originally developed for, designed by, and piloted for, a diverse group of YMSM. MyPEEPS Mobile will be tested in an randomized controlled trial with racially and ethnically diverse HIV-negative or unknown status YMSM aged 13-18 at four geographically diverse sites: Birmingham, Chicago, New York City, and Seattle, allowing for increased generalizability of findings.

Detailed description

Men who have sex with men (MSM) bear a greater burden of HIV/AIDS than any other population group in the US, comprising only 2% of the population but 56% of individuals living with HIV/AIDS. Although much of the increased incidence in HIV has been reported among YMSM, especially among racial and ethnic minority groups, and is linked to high-risk sexual behavior, there remains a dearth of evidence-based HIV prevention interventions for YMSM - and none that address racially/ethnically diverse YMSM. To address this need, this study leverages mobile technology and MyPEEPS, an existing theory-driven, multi-ethnic, group-level, evidence-based intervention for diverse YMSM. MyPEEPS is a manualized curriculum, comprised of 6 modules focusing on key intermediate social and personal factors, including knowledge (e.g., correct way to use a condom), self-efficacy for safer sex, interpersonal communication skills and behavioral skills. MyPEEPS is one of the only HIV prevention interventions in the literature that focuses on diverse adolescent MSM. Long-term sustainability of face-to face, group-level behavioral interventions, such as MyPEEPS, have been problematic for dissemination in at-risk populations, particularly among young racial and ethnic minority groups. In response to this challenge, the investigators propose to translate MyPEEPS from a face-to-face, group-based curriculum to a mobile, responsive-driven web-based platform, accessible by smartphone or other web-enabled devices, to increase accessibility and scalability for diverse YMSM. The ubiquitous nature of mobile phones in daily life, especially among 13-18 year olds, has created opportunities for health interventions in a portable format with enhanced privacy. Using a participatory approach, this study will incorporate user-centered design in the translation of the MyPEEPS intervention onto a mobile platform.

MeasureTime frameDescription
Condom Use ErrorsBaseline, 3, 6, and 9 months (Intervention group); Baseline, 3, 6, 9, and 12 months (Delayed Intervention group)The condom errors survey is a 12-item questionnaire was adapted to reflect a 6-week recall period. A sample question is when you used condoms during the last six weeks, how often was the condom put on the wrong side up so that it had to be flipped over? Response options ranged from 0=Never to 2=Always. Question scores ranged 0-2, values averaged and total scores ranged from 0 to 2, with lower values indicating fewer condom use errors.
Self-efficacy for Safer Sex and Situational Temptation for Unsafe SexBaseline, 3, 6, and 9 months (Intervention group); Baseline, 3, 6, 9, and 12 months (Delayed Intervention group)Participants were asked to respond to 10 questions assessing self-efficacy in practicing condom use and safer sex communication with a partner. A sample item is if I didn't want to have sex with my partner, I would be able to say no. Response options ranged from 1=Strongly agree to 4=Strongly disagree. Question scores ranged 1-4, values averaged and total scores ranged from 1 to 4, with lower values indicating higher self-efficacy

Response options ranged from 0=Never to 2=Always. Question scores ranged 0-2, values averaged and total scores ranged from 0 to 2, with lower values indicating fewer condom use errors.

Time frame: Baseline, 3, 6, and 9 months (Intervention group); Baseline, 3, 6, 9, and 12 months (Delayed Intervention group)

Population: The analytic sample included 760 of the 764 participants enrolled because 1 participant was enrolled in error (ineligible age) and withdrawn from the study prior to randomization and 3 participants were excluded from the analytic sample due to missing or invalid data.
