ABSTRACT
The Adult longitudinal research program, designed to measure the effect of aging on consumer behavior, is based on an integrated framework utilizing research from numerous disciplines. This chapter describes the research methodology, theoretical foundation, variables related to aging and consumer behavior, and implications from such a research program. The sampling methodology followed the total response method suggested by Dilman. A first-class mailing was sent several months prior to the administration of the questionnaire to correct for address changes and prepare panel members for the upcoming questionnaire. Although the notion of consumer life structure has parallels with lifestyle research, few psychographic items were utilized because there are few a priori predictions that can be made using psychographics. More importantly, there is no substantial theoretical foundation for lifestyles, especially in the context of aging. The Adult Longitudinal Panel utilized the approach of using variables suggested by previous theory and research rather than being a data-driven study with no theoretical underpinnings.
