Trial Outcomes & Findings for A Pragmatic Clinical Trial of MyPEEPS Mobile to Improve HIV Prevention Behaviors in Diverse Adolescent MSM (NCT NCT03167606)

NCT ID: NCT03167606

Last Updated: 2023-02-23

Results Overview

The number of condomless anal sex acts (CASA) will be evaluated at all time points using the AIDS-Risk Behavior Assessment (ARBA) adapted for YMSM. At each timepoint, participants were asked to report the past 3 month number of insertive and receptive anal sex acts during which condoms were not used.

Measure
Immediate Intervention
Study participants randomized to the immediate intervention arm will have access to the MyPEEPS Mobile from the baseline visit to 3-month follow-up visit. They will continue with follow-up visits at 6 months and 9 months, but will no longer have access to the MyPEEPS Mobile past the 3-month follow-up visit.

Delayed Intervention
Study participants randomized to the delayed intervention arm will complete visits at baseline, 3 months, 6 months, 9 months, and 12 months. They will have access to the MyPEEPS Mobile from the 9-month follow-up visit until the 12-month follow-up visit.

SECONDARY outcome

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sample included 760 of the 764 participants enrolled because 1 participant was enrolled in error (ineligible age) and withdrawn from the study prior to randomization and 3 participants were excluded from the analytic sample due to missing or invalid data.

Participants responded to the statement "I plan to use PrEP as a strategy to reduce my risk for HIV infection during the next three months" with response values ranging from 1=Very true to 4=Very untrue. Mean values were calculated for each group at each timepoint.

Immediate Intervention
n=379 Participants
Study participants randomized to the immediate intervention arm will have access to the MyPEEPS Mobile from the baseline visit to 3-month follow-up visit. They will continue with follow-up visits at 6 months and 9 months, but will no longer have access to the MyPEEPS Mobile past the 3-month follow-up visit. MyPEEPS Mobile: Mobile technology to deliver HIV prevention information specifically developed for at-risk YMSM.
Delayed Intervention
n=381 Participants
Study participants randomized to the delayed intervention arm will complete visits at baseline, 3 months, 6 months, 9 months, and 12 months. They will have access to the MyPEEPS Mobile from the 9-month follow-up visit until the 12-month follow-up visit.

OTHER_PRE_SPECIFIED outcome

Timeframe: 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.

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

OTHER_PRE_SPECIFIED outcome

Timeframe: 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.

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.
