Berlin Aging Study II (BASE-II)

One of the most salient aspects of aging is its heterogeneity. Some individuals maintain their health and preserve their cognitive abilities into advanced ages, whereas others show precipitous and early decline. To understand the mechanisms that produce this diversity of outcomes, we need to follow the trajectories of aging individuals over time. With this goal in mind, researchers from Berlin and Tübingen initiated the Berlin Aging Study II (Bertram et al., 2014). Like BASE, BASE-II was set up as a multidisciplinary and multi-institutional longitudinal study that captures a wide range of different functional domains. Geriatrics and internal medicine as well as immunology, psychology, genetics, sociology, and economics are among the disciplines involved. The study received financial support from the Federal Ministry of Education and Research. The recruitment of the BASE-II cohort, which was completed in 2013, resulted in a consolidated baseline sample of 1,600 older adults aged 60 to 80 years and of 600 younger adults aged 20 to 35 years (Bertram et al., 2014). Data from this baseline sample can be linked to the German Socio-Economic Panel Study (SOEP), a longitudinal panel survey that is representative of the German population, to estimate sample selectivity. See BASE-II in SOEP.

After extensive piloting, a comprehensive battery of cognitive tests and a psychological questionnaire were added to the baseline protocol in March 2013. The cognitive test battery is distributed across two testing sessions. It includes various facets of episodic memory as well as measures of working memory, cognitive control, fluid intelligence, reading skills, and decision making. It also includes a newly developed measure of subjective health, the subjective health horizon (SHH), to assess participants’ motivation to engage in explorative and novel activities (Düzel et al., 2016). The psychological questionnaire contains measures of self-reported health, well-being, personality, stress, coping, and of attitudes toward aging.
