Attrition and Generalizability of Cognitive Aging Studies - A Population-Based Perspective

Research project Determining the extent and consequences of different inclusion mechanisms are crucial for establishing generalizability of results beyond the study sample.

In the proposed project we will identify possible inclusion mechanism and study how estimates of cognitive performance are influenced by attrition prior to assessment. The combination of data from a longitudinal study on cognition, health, and aging (the Betula study) and Swedish register data will provide unique opportunities to study possible selection mechanisms and their implications.
