Appendix 2.2: Which sampling methodology (TLS or RDS) is more appropriate for the Key Population? If the answer is “Yes” to questions 1-4, TLS might be a preferred methodology: 1. Do individuals in the target population frequent venues?
2. Could the target population be identified at these venues?
3. Could the target population be accessed at these venues without drawing them unwanted attention?
4. Will all sub-groups within the population be captured at these venues?
If the answer is “Yes” to questions 5-8, RDS might be a preferred methodology: 5. Are individuals in the target population well-networked?
6. Will participants in the population be willing to recruit their peers into the study?
7. Do all sub-populations interact with each other to form a single network?
8. Can members of the target population identify each other?
