NCT ID: NCT03584282

Last Updated: 2024-06-05

Results Overview

Self-reported likelihood to recommend the text messaging intervention, via survey response, among those who received the text messaging intervention (may have been in the Standard of care group or the Peer Navigation group). Only participants who received the text messaging intervention are included in the analysis group.

Measure
Standard of Care/Text Messaging
Participants in this group will receive the standard of care the text messaging intervention. Text Messaging: The text messaging intervention will send three text messages per day from a library. One will be a reminder to take PrEP, one will include PrEP information, and the third will have the content of the participant's choosing from categories of harm reduction messages and health information. Participants will also select the time period to receive these texts. Study intervention groups changed over time - the original study design was a 2 x 2 factorial design with peer navigation, text messaging, both interventions, and standard of care arms. However, with slow enrollment, reports of text messaging being a possible barrier to enrollment, and a smaller anticipated effect compared to peer navigation, the intervention groups were collapsed to a comparison of peer navigation (whether or not text messaging was included) compared to standard of care.
Peer Navigation
Participants in this group will receive the peer navigator intervention. Peer Navigation: The peer navigation intervention will provide support from a peer that is responsive to a participant's individualized needs. Peer support may include phone call reminders, help refilling PrEP prescriptions, transit assistance, or other referrals.
