    Community Knowledge and Acceptance of Larviciding for Malaria Control in a Rural District of East-Central Tanzania

    The use of microbial larvicides, a form of larval source management, is a less commonly used malaria control intervention that nonetheless has significant potential as a component of an integrated vector management strategy. We evaluated community acceptability of larviciding in a rural district in east-central Tanzania using data from 962 household surveys, 12 focus group discussions, and 24 in-depth interviews. Most survey respondents trusted in the safety (73.1%) and efficacy of larviciding, both with regards to mosquito control (92.3%) and to reduce malaria infection risk (91.9%). Probing these perceptions using a Likert scale provides a more detailed picture. Focus group participants and key informants were also receptive to larviciding, but stressed the importance of sensitization before its implementation. Overall, 73.4% of survey respondents expressed a willingness to make a nominal household contribution to a larviciding program, a proportion which decreased as the proposed contribution increased. The lower-bound mean willingness to pay is estimated at 2,934 Tanzanian Shillings (approximately US$1.76) per three month period. We present a multivariate probit regression analysis examining factors associated with willingness to pay. Overall, our findings point to a receptive environment in a rural setting in Tanzania for the use of microbial larvicides in malaria control. © 2014 by the authors; licensee MDPI, Basel, Switzerland.

    Estimating willingness to pay: Do health and environmental researchers have different methodological standards?
    (Applied Economics, 2013-06-01) Özdemir, S; Johnson, FR
    Health and environmental economists have been employing Stated-Preference (SP) methods such as conjoint analysis or contingent valuation to estimate the monetary value of public health interventions and environmental goods and services. However, the quality of data and the validity of results are sensitive to a number of decisions researchers make. The aim of this study is to compare the degree of the current consensus among active researchers in the rapidly evolving area of SP methods in health and environmental valuation. We surveyed researchers who have published manuscripts on SP methods in the last 10 years. Researchers were presented with hypothetical SP studies with different attributes. They were first asked which study they would recommend to use to inform policy decisions, and then asked which study has better-quality. Our results show that good-practice SP methods vary among study features and among researchers with different amounts and kinds of research experience. Although health researchers had specific preferences on which study features were better, their quality judgements were not very consistent with their judgements about the acceptability of studies for policy analysis. On the other hand, environmental researchers had similar preferences over the study attributes for the two types of questions. © 2012 Copyright Taylor and Francis Group, LLC.
