Although quantitative methods used in epidemiology and biostatistics are useful for assessing health care needs and the effects of research interventions on improved health status, qualitative methods have long been advocated as the approach of choice to assess health behaviors. Unfortunately, many qualitative methods used are cumbersome and not easily measurable. The author presents an approach, foldback analysis, that combines better the rich detail provided by qualitative studies with the numerical preciseness of quantitative analysis. The individual methods used in the foldback process are not new, but the multimethod combination and sequence is distinct. This article presents the methodology discussing each subprocess and describing the experiences of the author using foldback analysis in health behavior research in cross-cultural settings.
