Query: Pilot Testing an Artificial Intelligence Algorithm That Selects Homeless
  Youth Peer Leaders Who Promote HIV Testing   Objective. To pilot test an artificial intelligence (AI) algorithm that
selects peer change agents (PCA) to disseminate HIV testing messaging in a
population of homeless youth. Methods. We recruited and assessed 62 youth at
baseline, 1 month (n = 48), and 3 months (n = 38). A Facebook app collected
preliminary social network data. Eleven PCAs selected by AI attended a 1-day
training and 7 weekly booster sessions. Mixed-effects models with random
effects were used to assess change over time. Results. Significant change over
time was observed in past 6-month HIV testing (57.9%, 82.4%, 76.3%; p < .05)
but not condom use (63.9%, 65.7%, 65.8%). Most youth reported speaking to a PCA
about HIV prevention (72.0% at 1 month, 61.5% at 3 months). Conclusions. AI is
a promising avenue for implementing PCA models for homeless youth. Increasing
rates of regular HIV testing is critical to HIV prevention and linking homeless
youth to treatment.
