Drivers of vaccine decision-making in South Africa: A discrete choice experiment Universiteit Hasselt KU Leuven Universiteit Antwerpen
To increase vaccination coverage, it is essential to understand the vaccine decision-making process. High population coverage is required to obtain herd immunity and to protect vulnerable groups in terms of age (e.g. the very young) or health (e.g. immunodeficiency). Vaccine confidence and coverage in South Africa are relatively low, opening the window for sustained outbreaks of vaccine-preventable diseases in a country facing one of the most ...
Farmers’ preferences for cotton cultivation characteristics : a discrete choice experiment in Burkina Faso Universiteit Gent
While a fierce debate about the advantages and disadvantages of genetically modified crops is ongoing, it is surprising that farmers are often not consulted. In Burkina Faso, where insect resistant Bollgard II (R) cotton (further termed Bt cotton) was commercially released in 2008, studies highlight that cotton producers are in general satisfied with the reduction in insecticide use while the economic benefits are a source of controversy. To ...
What nutrition label to use in a catering environment?: a discrete choice experiment Universiteit Gent
To tax or to ban? A discrete choice experiment to elicit public preferences for phasing out glyphosate use in agriculture Universiteit Antwerpen
In 2023, the European Union will vote on the reauthorization of glyphosate use, renewed in 2017 despite concern on impacts on the environment and public health. A ban is supported by several Member States but rejected by most farmers. What are citizens’ preferences to phase out glyphosate? To assess whether taxation could be an alternative to a ban, we conducted a discrete choice experiment in five European countries. Our results reveal that the ...
Comparing Discrete Choice Experiment with Swing Weighting to Estimate Attribute Relative Importance: A Case Study in Lung Cancer Patient Preferences KU Leuven
INTRODUCTION: Discrete choice experiments (DCE) are commonly used to elicit patient preferences and to determine the relative importance of attributes but can be complex and costly to administer. Simpler methods that measure relative importance exist, such as swing weighting with direct rating (SW-DR), but there is little empirical evidence comparing the two. This study aimed to directly compare attribute relative importance rankings and weights ...
Public preferences for prioritizing preventive and curative health care interventions: a discrete choice experiment. KU Leuven Universiteit Antwerpen
BackgroundSetting fair health care priorities counts among the most difficult ethical challenges our societies are facing.ObjectiveTo elicit through a discrete choice experiment the Belgian adult population's (18-75 years; N = 750) preferences for prioritizing health care and investigate whether these preferences are different for prevention versus cure.MethodsWe used a Bayesian D-efficient design with partial profiles, which enables considering ...
How to reform western care payment systems according to physicians, policy makers, healthcare executives and researchers: a discrete choice experiment KU Leuven Universiteit Gent Universiteit Antwerpen
BACKGROUND: Many developed countries are reforming healthcare payment systems in order to limit costs and improve clinical outcomes. Knowledge on how different groups of professional stakeholders trade off the merits and downsides of healthcare payment systems is limited. METHODS: Using a discrete choice experiment we asked a sample of physicians, policy makers, healthcare executives and researchers from Canada, Europe, Oceania, and the United ...
No Such Thing as a Free-Rider? Understanding Drivers of Childhood and Adult Vaccination through a Multicountry Discrete Choice Experiment KU Leuven Universiteit Antwerpen
Increased vaccine hesitancy and refusal negatively affects vaccine uptake, leading to the reemergence of vaccine preventable diseases. We aim to quantify the relative importance of factors people consider when making vaccine decisions for themselves, or for their child, with specific attention for underlying motives arising from context, such as required effort (accessibility) and opportunism (free riding on herd immunity). We documented ...
Quantifying the public's view on social value judgments in vaccine decision-making: A discrete choice experiment. KU Leuven Universiteit Antwerpen
Vaccination programs generate direct protection, herd protection and, occasionally, side effects, distributed over different age groups. This study elicits the general public's view on how to balance these outcomes in funding decisions for vaccines. We performed an optimal design discrete choice experiment with partial profiles in a representative sample (N = 1499) of the population in the United Kingdom in November 2016. Using a panel mixed ...
