Focus group methodology in the development of a survey to measure physician use of cancer staging systems.
Accurate classification and staging of cancers enables physicians to select appropriate treatments, to evaluate outcomes of health management more reliably, to compare and interpret statistics reported from various institutions on a local, regional, national and international basis more consistently and to assist exchanges of information between different centers of treatment. This paper examines group interview methodology to develop the first-ever survey of Canadian cancer care specialists pertaining to staging systems. It is shown how the responses provided by participants contributed to the formulation of testable hypotheses and shaped the development of survey questions. As well, experiences are shared regarding the technical issues that arose using the focus group technique with physicians. In conclusion, there is a brief discussion of how the use of staging classification systems might be understood from the perspective of diffusion theory and social marketing (i.e., how information about cancer staging has been communicated and disseminated.
