Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of participant DUFB use over time, as assessed by an interviewer-administered survey using structured open-ended questions
Time Frame: 5 months
Use of DUFB at baseline assessed with yes/no response. At each of the the 3 follow-up surveys waves (1.5 months, 3 months, and 5 months), participants will be asked if they have used DUFB in the past month (yes/no), and if yes, how many times.
