BACKGROUND Understanding which attributes of colorectal cancer (CRC) screening tests drive older adults' test preferences and choices may help improve decision making surrounding CRC screening in older adults. MATERIALS AND METHODS To explore older adults' preferences for CRC-screening test attributes and screening tests, we conducted a survey with a discrete choice experiment (DCE), a direct...

In contrast to the classical discrete choice experiment, the respondent in a rank-order discrete choice experiment, is asked to rank a number of alternatives instead of the preferred one. In this paper, we study the information matrix of a rank order nested multinomial logit model (RO.NMNL) and introduce local D-optimality criterion, then we obtain Locally D-optimal design for RO.NMNL models in...

We conduct a discrete choice experiment (DCE) to determine how important aid effectiveness is to people relative to other criteria for choosing countries to support with bilateral foreign aid. We find that aid effectiveness is important, on a par with recipient-country need as proxied by the level of hunger and malnutrition. Both criteria are more important than others.

BACKGROUND The provision of additional information is often assumed to improve consumption decisions, allowing consumers to more accurately weigh the costs and benefits of alternatives. However, increasing the complexity of decision problems may prompt changes in information processing. This is particularly relevant for experimental methods such as discrete choice experiments (DCEs) where the r...

Purpose The purpose of this study was to assess patient preferences regarding pharmacological treatment attributes for bipolar depression using a discrete choice experiment (DCE). Methods Adult members of an Internet survey panel with a self-reported diagnosis of bipolar depression were invited via e-mail to participate in a web-based DCE survey. Participants were asked to choose between hypo...

BACKGROUND There is growing evidence of a reluctance to allocate health care solely on the basis of maximizing quality-adjusted life years (QALYs). Stated preference methods can be used to elicit preferences for efficiency vs. equity in the allocation of health-care resources. OBJECTIVE To compare discrete choice experiment (DCE) and constant-sum paired comparison (CSPC) methods for eliciting...
