Why is it that quantitative and qualitative researchers on health issues often have divergent findings and conclusions? Exploration of such differences can be a useful way of bringing separate intellectual enclaves in medical sociology together and also can stimulate future inquiries. Some differences can be resolved by more precise definitions, by comparable frequency and timing of measurement, and by careful evaluation of meaning contexts. The triangulation of methods, using diaries as a bridge between surveys and qualitative measurement, offers particular promise. Improved theory on the relationships of method to data, and more attention to behavioral sequences and the social context of measurement, can serve as a stimulant to innovative solutions.
