“…Furthermore, research documents a strong link between substance use and illegal activity (Ford & Rigg, 2015; Silva, Schrager, Kecojevic, & Lankenau, 2013) and between substance use and HIV/STI risk (Aalsma, Tong, Wiehe, & Tu, 2010; Teplin, Mericle, McClelland, & Abram, 2003). As youth under community supervision are frequently disconnected from services and may miss school-based or other community-located HIV/STI interventions, juvenile community supervision agencies are uniquely positioned to provide HIV/STI testing and prevention programming to a high-risk group of vulnerable youth (Elkington et al, 2015). Access to timely HIV prevention, including Pre-Exposure Prophylaxis (PrEP), can reduce risk of HIV infection among youth under community supervision, and early identification (i.e., HIV testing) with prompt referral to treatment for youth who are found to be living with HIV and STIs, may reduce the transmission of the infections in their communities (Allen, Gordon, Krakower, & Hsu, 2017; Donenberg, Emerson, & Kendall, 2018; Donenberg, Emerson, Mackesy-Amiti, & Udell, 2015; Godin et al, 2003; Tolou-Shams, Stewart, Fasciano, & Brown, 2010).…”
