Qualitative research: what does it have to offer to the gerontologist?

The growing challenges of promoting health and managing illness in an ever-changing health care system require an arsenal of research approaches. Qualitative methods have a long tradition in disciplines such as sociology and anthropology and are being used with greater frequency as interdisciplinary health-related disciplines attempt to understand and explain complex problems. The purpose of this article is to define and describe the main features of qualitative research and to examine ways in which this methodology is relevant and useful in gerontological studies. A concise comparison of quantitative and qualitative methods is made, and suggestions are provided for when qualitative approaches are useful. A review of the three most common approaches is provided. Most important, references are provided for those gerontologists interested in learning more about qualitative research methods.
