ABSTRACT
OBJECTIVE:
To quantify stated preferences for latrine use and construction in Amhara, Ethiopia, using Discrete Choice Experiments (DCEs).METHODS:
We conducted image-based DCEs to assess preferences for latrine use (stratified by gender) and construction (among men only) in Amhara, Ethiopia. Preference was quantified using a conditional logistic model to estimate utilities and corresponding odds ratios associated with a set of latrine attributes.RESULTS:
For latrine use, tin roof, handwashing stations and clean latrines had the highest relative utility coefficients. Tin roof was preferred to no roof for use (Women OR 3.68, 95% CI 3.18-4.25; Men OR 3.75, 95% CI 3.21-4.39) and new latrine construction (5.92, 5.04-6.95). Concrete slabs, a critical aspect of improved sanitation, was not preferred to dirt floors for use (Women 0.87, 0.75-1.00; Men 1.03, 0.88-1.20), but was preferred for new construction (1.52, 1.30-1.78). We did not observe any trends in preference for direct (monetary) or indirect cost (labour days), so we were not able to elicit trade-offs between latrine attributes and these costs for the construction of new latrines.CONCLUSION:
Our findings suggest similar latrine use preferences between men and women. We found that tin roofs are the most strongly preferred latrine characteristic, but concrete slabs, commonly promoted in sanitation programmes, were not preferred for use. We demonstrate the utility of DCEs to elicit stated preferences for latrine use and construction among community members who have myriad motivations for using and making improvements to their sanitation facilities, including the ease of cleaning and hygiene, durability, or privacy and comfort.Palavras-chave
