Objective. To examine preferences for HIV test methods using conjoint analysis, a method used to measure economic (utilities). Data Sources. Self‐administered surveys at four publicly funded testing locations in San Francisco, California, between November 1999 and February 2000 ( n =365, 96 percent response rate). Study Design. We defined six important attributes of tests their levels (location, price, ease collection, timeliness/accuracy, privacy/anonymity, counseling). A fractional...
Abstract Aims Medication non‐adherence is particularly common in patients with Type 2 diabetes. We constructed a discrete‐choice experiment to examine the relative importance of oral glucose‐lowering medication features and estimate likely effect effectiveness side effects on adherence diabetes UK USA. Methods Preferences were elicited using cross‐sectional, web‐enabled survey. Patients self‐reported physician‐made diagnosis diabetes, who currently taking medications recruited through an...
Best-worst scaling (BWS), also known as maximum-difference scaling, is a multiattribute approach to measuring preferences. BWS aims at the analysis of preferences regarding set attributes, their levels or alternatives. It stated-preference method based on assumption that respondents are capable making judgments best and worst (or most least important, respectively) out three more elements choice-set. As true discrete choice experiments (DCE) generally, avoids weaknesses rating ranking scales...
Background: Medication nonadherence is high among patients with bipolar disorder, and may lead to poor clinical outcomes, decreased quality of life, increased resource utilization. Objective: To investigate the factors associated assess effect patient-stated preferences on stated adherence hypothetical medications. Research Design: A choice-format stated-preference Web survey was administered. In each choice question, were asked choose 2 or 3 different Each question followed by a asking...
Independent applications of open-ended and dichotomous-choice formats are compared using tests means, estimating joint likelihood functions nonparametric distributions. The null hypothesis no difference in the estimates central tendency cannot be rejected for two out three data sets, while estimated standard deviations significantly different all sets. In addition, actual means exceed those from comparable synthetic suggesting either questions underestimate values or bid structures may lead...
Objective. To compare and contrast methods findings from two approaches to valuation used in the same survey: measurement of “attitudes” using simple rankings ratings versus “preferences” conjoint analysis. Conjoint analysis, a stated preference method, involves comparing scenarios composed attribute descriptions by ranking, rating, or choosing scenarios. We explore possible explanations for our focus groups conducted after quantitative survey. Methods. A self‐administered survey, measuring...
This study uses stated-preference (SP) analysis to measure willingness pay (WTP) reduce acute episodes of respiratory and cardiovascular ill health. The SP survey employs a modified version the health state descriptions used in Quality Well Being (QWB) Index. four attributes are symptom, episode duration, activity restrictions cost. Preferences elicited using two different formats: graded-pair discrete-choice. formats cause subjects focus on evaluation strategies. Combining elicitation...
A specialized survey of Maine households' responses to information about the risks associate d with radon concentrations in their homes and water supplies was use evaluate how they form risk perceptions. The findings support a modified Bayesian learning model describe individual s used revise Moreover, dividuals who took some mitigating actions reported lower percep tions after that action. overall results are potentially importan t programs as policy instruments for r eduction because...
