Issues in the Design of Discrete Choice Experiments
The use of preference-elicitation tasks—in particular, discrete choice experiments (DCEs)—in health economics has grown significantly in recent decades . The most widely used DCE approach asks respondents to consider a series of hypothetical choices between alternatives (here called choice tasks), and to specify which alternative they prefer. The use of choice tasks in other areas—especially psychology, transportation, marketing and agriculture—has a more established history. Health preference studies have been conducted for about as long [2, 3], but not to the same extent; the relatively late uptake in preference evidence in health is surprising in some regards as patient and population values concerning health have always been key components of a range of questions from health policy to clinical practice, and often cannot be directly observed, a problem exacerbated by the lack of a perfectly competitive market . Though there is broad consensus on the value...
