Contingency Management
Yoked Contingency Management
Participants will submit a urine sample every Monday, Wednesday, and Friday for 8 weeks (a total of 24 urine samples). Samples will be tested for stimulant metabolites. Increasingly valuable incentives will be provided for urine samples that lack metabolites of stimulant drugs. Participants reporting recent (i.e., < 48 hours) exposure to HIV viral inoculum will have the opportunity to initiate Truvada (1 pill daily for 28 days).
Participants will submit a urine sample every Monday, Wednesday, and Friday for 8 weeks (a total of 24 urine samples). Samples will be tested for stimulant metabolites. Incentives will be provided to participants independent of stimulant drug use and determined in the same rate and timing as a randomly selected participant in the active CM condition. Participants reporting recent (i.e., < 48 hours) exposure to HIV viral inoculum will have the opportunity to initiate Truvada (1 pill daily for 28 days).
