Outcome measures
Primary outcome
The main endpoint of this study is the relative importance of the selected attributes in the CBC analysis, expressed in the utility of each individual attribute.
Utilities indicate how much the difference between the levels of one attribute affects the decision of a subject to take part in a screening program.
Secondary outcome
Expected utility scores for existing screening methods. This is the expected utility for an existing screening method for EAC, which can be calculated by applying its current characteristics to the utility function.
- Expected uptake of EAC screening using various screening methods.
- Differences in preference structures among subgroups in the population.
- Willingness To Pay.
Background summary
To explore preferences for EAC screening tests attributes and screening test, a survey with a choice-based conjoint analysis will be conducted. Subjects will be asked on their preferences for aspects of EAC screening methods. Each individual will answer 12 discrete choice questions presenting two hypothetical tests comprised of 5 attributes.
Study objective
patient preferences
Study design
time frame: 8 months
Intervention
Choice-based conjoint analysis (CBC)
CBC analyses involve surveys in which respondents are asked to choose between hypothetical alternatives defined by a set of differing attributes. The method is based on the idea that goods and (health care) services can be described by their characteristics, also called attributes, and each attribute is assigned a range of predefined dimensions called attribute-levels. The levels of attributes will be varied systematically in a series of questions and respondents will choose the option that they prefer for each question.
Ultimately, CBC analysis can determine which attributes are driving patients preferences, the trade-offs people make between attributes and how changes in attributes can lead to changes in preferences and screening uptake.
