Course Description:

In recent years the amount of data that can be brought to bear on issues of human aging has grown considerably. Specifically, comparable data are now available for selected birth cohorts that are separated by widely varying historical circumstances. Although the majority of these data sets are cross-sectional, roughly comparable longitudinal data on diverse birth cohorts are available as well. The availability of such multiple surveys involving different cohorts offers rich opportunities for cross-cohort validation of findings previously demonstrated only on single cohorts.

To capitalize on the availability of these multiple data sets, sophisticated methodological and statistical techniques must be employed to address a number of thorny conceptual and technical problems, including the following: the lack of exact comparability across waves within surveys as well as across surveys themselves; relating macro-level variables that change over time to relationships at the micro level; and the comparison of differently incomplete estimates of complex models obtained from a variety of data sets. These are the broad issues that will be addressed in the workshop, which is targeted for those actively engaged in or contemplating the secondary analysis of multiple data sets.

A preliminary list of specific topics to be covered in the one-week workshop includes: (1) an overview of the available multiple data sets and a conceptual framework for ransacking them; (2) the analysis of repeated cross-sectional surveys, including traditional approaches to resolving the age-period-cohort problem and newer cohort replacement techniques; (3) multi-level models and the relationships between macro- and micro-level variables; (4) multi-method multi-trait analysis and composite approaches to measurement comparability; (5) configural and factorial invariance in measurement models; and (6) the analysis of incomplete data within survey waves, across survey waves within data sets, and across multiple data sets.

To facilitate the learning process, the workshop will consist of a traditional didactic segment, coupled with hands-on experience using multiple data sets. The morning (3-hour) and early afternoon (1.5-hour) sessions will be devoted to lecture. The late afternoon (2-hour) sessions will involve the computer laboratory, which provides high-end Internet- linked computers reserved for workshop participants. Several examples using different multiple data sets will be keyed to each specific topic. At the end of each daily laboratory session, there will be a half-hour review and question-and-answer period.

Participants will be provided with the course outline, readings, examples, data sets, and codebooks in advance in a three-ring binder and on an accompanying CD-ROM. Multiple data sets will be selected that represent the full range of situations likely to be encountered, from the simplest case of fully replicated repeated cross-sectional surveys of the same population (e.g., pooled data from the General Social Surveys [GSS]), to the more complicated case of not-fully replicated cross-sectional surveys of the same population (e.g., the Studies on Aging [SOA-I and SOA-II]); to the even more complicated case of not-fully replicated longitudinal surveys of somewhat different populations (e.g., the Established Populations for the Epidemiologic Study of the Elderly [EPESE]); to the rather complex case of not-fully replicated longitudinal surveys of rather different age cohorts (e.g., the HRS and AHEAD).
