Throughout the nine month baseline data collection period we will maintain a sampling frame of VDTs from which to recruit participants. Sampling frames will be updated monthly, with the addition of sporadically occurring VDTs and the removal of VDTs that are no longer viable (have failed to yield sufficient eligible participants or are infeasible due to practical constraints). Each month, after the sampling frame is updated, VDTs will be randomly selected and placed on the sampling event calendar. At the time of each sampling event, trained staff will systematically approach (e.g. every third woman appearing to be 15 years or older) potential participants who enter a predefined sampling area of the venue. Potential participants will be screened to determine eligibility. Members of the target population who meet all of the eligibility criteria and who agree to participate in the study will then complete informed consents prior to enrollment. They will self-administer the study questionnaire, and will be offered an incentive valued at $10 for their time.
