Preferences and willingness to pay for STBBI testing study

Initiative summary

This study is using discrete choice experiments (DCEs), a well-established stated preference methodology, to evaluate the relative importance of different aspects of testing for different communities. The study team is also evaluating the willingness of these groups to trade-off between these aspects.  

The team is developing and conducing two DCEs as part of this project. A qualitative study through focus groups or interviews with the key populations, including current and potential testing users (the gay, bisexual and other men who have sex with men (GBMSM) community; African, Caribbean, and Black (ACB) community; Indigenous groups; sex workers; and drug users) will first be conducted to determine the main attributes and levels required for the DCE design. The first DCE will then be conducted and administered among members of the general public. This will determine the most important attributes of testing options for broad populations and the public acceptance of these options. The second DCE will be administered to a sample of each of the five key populations listed above.

Initiative objectives and goals

This project’s goal is to get a better understanding of testing preferences, both among the general public and within key populations, to support policy and program planning for STBBI testing.

The role of this initiative to end the HIV epidemic

A better understanding of testing preferences can support more effective planning for STBBI testing delivery and access.

Meaningful engagement with people with lived experience

Through an initial qualitative study, the researchers are aiming to use focus groups or semi-structured interviews with 3 to 8 participants from each of the key populations. For the discrete choice experiments, the researchers plan to recruit 5000 to 10000 public members and a minimum of 300 individuals from each key population.
