Clinical Trial Summary

The aim of this study is to examine the utility of neuroimaging technique to evaluate pre-exposure prophylaxis (PrEP) promotion messages for men who have sex with men (MSM) at risk of HIV in Baltimore.

Description:

This study will examine the utility of neuroimaging technique to evaluate PrEP promotion messages for MSM at risk of HIV in Baltimore. The investigators hypothesize that participants viewing top messages developed via open contests will show higher brain activation in the Medial Prefrontal Cortex (MPFC) regions than those viewing messages developed by a social marketing approach. The investigators further hypothesize brain activation in the MPFC regions is significantly more correlated with PrEP behavioral intention, initiation, and action than self-reported message effectiveness.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	change of neural activity	change of the ratio of oxygenated (O2HB) to deoxygenated (HHB) hemoglobin in the Medial Prefrontal Cortex (MPFC) regions measured by functional near infrared spectroscopy (fNIRS)	20 seconds between participants start and finish reviewing the messages
Primary	change of willingness and behavioral intention to take PrEP	questions on willingness and behavioral intention to take PrEP. Participants will be asked, "Suppose that PrEP is at least 90% effective in preventing HIV when taken daily. How likely would you be to take PrEP if it were available for free?" with responses ranging from "I would definitely take it" to "I would definitely not take it." Participants will be asked, "PrEP is currently available with a prescription from your doctor and research has shown that a majority of insurance companies cover most or all of the costs of PrEP. Do you plan to begin PrEP?" Response options range from "Yes, I will definitely begin taking PrEP" to "No, I definitely will not begin taking PrEP."	30 days between baseline and follow up
Secondary	PrEP action and initiation	questions on "Have you spoken with a provider about PrEP during the past 30 days?" and "Have you started taking PrEP during the past 30 days?"	30-day follow up
