Combining Qualitative and Quantitative Methods in Health Research with Minority Elders: Lessons from a Study of Dementia Caregiving

Abstract

The merits of combining qualitative and quantitative methods are well known. While used often in evaluation research, a combined methods approach is rarely used in health studies with minority elders. This approach can be particularly useful for overcoming theoretical and recruitment problems specific to health research with minority elders. A cross-cultural study of family caregiving for demented-affected elders is presented to show how issues of rigor, theory building, language, and cultural adaptation of diagnostic tools can be effectively dealt with using combined methods. Specifically, the authors found qualitative data valuable in ensuring the cultural appropriateness of quantitative measures and in confirming causal relationships to which quantitative data pointed. They also found applying quantitative data collection techniques to qualitative data collection to be useful in theory building and in overcoming some of the reliability problems associated with qualitative data.
