To arrive at these weights, we used a discrete choice experiment (DCE) reported in this study. More details here - www.linkedin.com/feed/update/... Great collaboration with Instituto Nacional de Saúde as part of the Maputo Sanitation Trial. [5/5]

If a given population thinks that avoiding disgust is more important than avoiding shame, then the weights should reflect this, e.g. 0.22 for disgust and 0.18 for shame instead of 0.20 for both. [4/n]

The 5 answers are combined as an index ranging 0-1, but the five attributes are not weighted equally. Why? Because for a measure to be used cost-effectiveness or benefit-cost analysis, attributes should be weighted according to people's values. [3/n]

The SanQoL-5 is a validated index which measures people’s experience of sanitation with 5 questions about privacy, disgust, safety, shame, and disease – more details on the website [www.sanqol.org] [2/n]
