This study uses contingency management, specifically $10 financial incentives for participation in SARS-CoV-2 testing and $10 for participating in COVID-19 vaccination. It also uses a motivational enhancement intervention which is a brief conversation with clients to improve intrinsic motivation for testing and vaccination. Thus, the clinical trials portion of this study is a randomized control trial (N = 349) in which 177 participants will be assigned to contingency management plus the Connect2Test intervention and 172 will be assigned to the contingency management alone (i.e. services as usual). There will be a per site quota to ensure there are relatively equivalent numbers of participants per site to avoid site-specific biases. The data collection software (e.g., Qualtrics, PowerBI) will randomly assign individuals to condition in real time, after a participant consents to participate in the study.
