Patients’ preferences for esophageal cancer screening strategies

Subjects will be asked on their preferences for aspects of EAC screening methods.

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.
