Using focus groups to develop contingent valuation scenarios—A case study of womenʹs groups in rural Nepal

The construction of a contingent valuation (CV) scenario forms a critical component of willingness-to-pay (WTP) survey design, especially when working across diverse cultural and socio-economic settings. However, the methods used to develop CV scenarios have not been well reported in the health economics literature. This paper begins by describing how qualitative methods can be used to develop CV surveys. It then presents a case study illustrating how focus groups were used to develop a CV survey to value a womenʹs group intervention in rural Nepal. A series of focus group discussions were conducted with three stakeholder groups. These were used to determine the most appropriate description of the good to be valued and the means by which payment would be elicited. These methods were very helpful in designing the survey tool and choosing the key attributes to describe the intervention. They also familiarised field workers with the concept of WTP. Further work of this kind will help to highlight additional advantages and limitations of qualitative approaches to survey design.
