Developing a Methodological Research Program for Longitudinal Studies: Proceedings of a Workshop—in Brief.

One of the strategic objectives of the National Institute on Aging (NIA) is to "support the development of population-based data sets, especially from longitudinal studies, suitable for analysis of biological, behavioral, and social factors affecting health, well-being, and functional status through the life course." To contribute to that objective and to inform the development of a methodological research program for longitudinal studies, the Committee on National Statistics held a public workshop in June 2017. The discussion focused on challenges that are specific to the types of longitudinal studies supported by NIA and aimed to identify areas of methodological research that could be pursued in order to benefit from emerging methods, new techniques, or other opportunities to enhance the data and increase data collection efficiency. This publication summarizes the presentations and discussions from the workshop.
