The survey research method is a commonly used social science data collection technique. It has recently received expanded application in research on life-span human development, particularly in the area of adult development and aging (Campbell, Abolafia, & Maddox, 1985; Cutler, 1979; Markides, Liang, & Jackson, 1990). The purpose of this chapter is to explore conceptual and methodological issues in the application of survey research methods to the study of life-span human development.
