Bridges, JFP, Hauber, AB, Marshall, D, et al. Conjoint Analysis Applications in Health—a Checklist: A Report of the ISPOR Good Research Practices for Conjoint Analysis Task Force.Value Health 2011;14:403-13.
Background: The application of conjoint analysis (including discretechoice
experiments and other multiattribute stated-preference methods)
in health has increased rapidly over the past decade. A wider
acceptance of these methods is limited by an absence of consensusbased
methodological standards. Objective: The International Society
for Pharmacoeconomics and Outcomes Research (ISPOR) Good Research
Practices for Conjoint Analysis Task Force was established to
identify good research practices for conjoint-analysis applications in
health. Methods: The task force met regularly to identify the important
steps in a conjoint analysis, to discuss good research practices
for conjoint analysis, and to develop and refine the key criteria for
identifying good research practices. ISPOR members contributed to
this process through an extensive consultation process. A final consensus
meeting was held to revise the article using these comments,
and those of a number of international reviewers. Results: Task
force findings are presented as a 10-item checklist covering: 1) research
question; 2) attributes and levels; 3) construction of tasks; 4) experimental
design; 5) preference elicitation; 6) instrument design; 7) datacollection
plan; 8) statistical analyses; 9) results and conclusions; and
10) study presentation. A primary question relating to each of the 10
items is posed, and three sub-questions examine finer issues within
items. Conclusions: Although the checklist should not be interpreted
as endorsing any specific methodological approach to conjoint analysis,
it can facilitate future training activities and discussions of good
research practices for the application of conjoint-analysis methods in
health care studies.
Keywords: conjoint analysis, discrete-choice experimental, economic evaluation, good research practice.
