Abstract
In this article, the authors demonstrate how qualitative methods can form a foundation for quantitative research by improving instrument validity, informing the data collection process, and improving cost-effectiveness in a study of physician decision making. To test terminology, applicability, and comprehension of a quantitative questionnaire for doctors in the United States and United Kingdom, each country's researchers conducted physician focus groups with questions organized around the experiment, including (a) validity of video vignettes of actor “patients,” (b) population accessibility, (c) level of remuneration, (d) appropriate endorsement figure, and (e) question comprehension. Focus group data collected during instrument development and fieldwork planning streamlined processes and achieved cost efficiencies and effectiveness for the overall study. Beyond simply adding a post hoc qualitative component to an already free-standing quantitative methodology, focus groups were used in the study formulation, where the qualitative methodology was integrated into the process of developing a valid survey instrument.Keywords
