Application of Discrete-Choice Experiment Methods in Tobacco Control: A Systematic Review

Abstract

BackgroundEconomic evidence relating to tobacco control is generally derived from the cost effectiveness of smoking-cessation programs or the economic impact of tobacco-induced disease, based on revealed-preference data. However, empirical estimates from stated-preference data on tobacco users’ preferences, smoking behaviour and smoking cessation aids using analytical techniques such as discrete-choice experiments (DCEs) could be important for policy decision making in tobacco control.ObjectivesOur objective was to review the practice and utility of DCE methodology across nicotine- and tobacco-related issues, particularly smoking and smoking-cessation behaviour, anti-smoking policies and preferences for smoking-cessation aids.MethodsWe searched the PubMed, MEDLINE and ECONLIT databases for full-text original research articles on tobacco-related issues published between January 2000 and April 2016 that used a DCE method. We summarised the evidence and methodological characteristics of DCEs according to Lancsar and Louviere, 2008.ResultsOur review of the 12 eligible studies showed that DCE methodology was used to elicit smoker preferences and to evaluate tobacco-control policies. The majority of the studies were published in the last 5 years. The areas of application were smoking cessation, smoking behaviour, electronic cigarette use, water-pipe smoking and tobacco packaging. Monetary attributes were the most influential attributes in all studies. The design of the DCEs varied.ConclusionDCE studies of tobacco-related issues were methodologically consistent with guidelines proposed for conducting health-related DCEs.Electronic supplementary materialThe online version of this article (doi:10.1007/s41669-017-0025-4) contains supplementary material, which is available to authorized users.

Sustainable Diet Dimensions. Comparing Consumer Preference for Nutrition, Environmental and Social Responsibility Food Labelling: A Systematic Review

“…As the majority of reviewed studies were choice experiments an assessment form was designed to appropriately assess these studies. Criteria were based on the "good-practice" checklist of Lancsar and Louviere [33]; a method used in two recent systematic reviews of choice experiment literature where the criteria were also adapted to suit reviewed studies [34,35]. Two criteria relating to single dimensional attribute criteria and suitability of econometric choice model were excluded to avoid disadvantaging the alternative study designs included.…”

To “Vape” or Smoke? Experimental Evidence on Adult Smokers

“…We conduct a discrete choice experiment (DCE) in a sample of adult tobacco cigarette smokers to help address these information gaps. DCE, a stated preference technique, is increasingly employed by economists to study tobacco‐related products (Buckell, Marti, and Sindelar ; Czoli et al ; Ida and Goto ; Kenkel et al ; Marti , ; Pesko et al ; Regmi et al ; Shang et al ). These methods are grounded in consumer choice theory established by Lancaster ().…”

Physical Activity in the Daily Life of Adolescents: Factors Affecting Healthy Choices from a Discrete Choice Experiment

“…This study investigates adolescents’ preferences by means of a discrete choice experiment (DCE). Discrete choice models represent a class of experiments widely applied in the fields of marketing, transport, as well as in environmental, labor and health economics and policy [ 84 , 85 , 86 , 87 , 88 ]. They are ultimately intended to extrapolate respondents’ preferences starting from their stated preferences in hypothetical scenarios [ 89 ].…”
