The Berlin Aging Studies (BASE)

Dynamic Modeling of Longitudinal Change and Mortality

During the 20th century, average life expectancy nearly doubled. More and more individuals in current cohorts of older individuals experience additional years of life between the ages of 70 and 100+. What do these added years mean in terms of levels of functional capacity and quality of life? What are the constraints on mental and physical capacities in the last years of life? Given the heterogeneity of aging trajectories and outcomes, longitudinal studies of individual development are crucial in providing answers to these questions. Since 1989, members of the Center for Lifespan Psychology have been investigating age- and death-related changes in psychological functioning from age 70 to 100+ in the context of the Berlin Aging Study I (BASE). Recently, a new focus has been added by establishing BASE-II to address antecedents of healthy aging. Both BASE and BASE-II are collaborative, multidisciplinary studies that involve collaborators from other institutions inside and outside Berlin. In the following, we summarize recent developments in both studies.
