Cognition and aging

Cognitive functioning of older adults


In the table below, entries in the left column refer to the related documentation, while the numbers in the cells of columns LASA-B to LASA-I refer to the corresponding LASA-data files (e.g. '022' in column B-G refers to 'LASAB022', 'LASAC022', 'LASAD022', 'LASAE022', 'LAS2B022', and 'LASAG022' respectively). Underlined entries are hyperlinks, hovering with your mouse over the underlined wave names will show you the years in which the corresponding measurements took place.

For LASA-3B (cohort 3, Baseline), and LASA-MB (Migrants 1st cohort, Baseline) some files are not yet available since processing of the underlying data is still in progress. In 2015 a new measurement has been started containing respondents from cohorts 1, 2, and 3: the I-wave (still in progress). Note that the MB-cohort which was examined in 2013-2014 has its own sampling frame.

Blue data files: no links to variable information available, in most cases due to copyrighted © material.

More details about the LASA-waves, see LASA-introduction.
* Some of the MB-data and most of the I-data are not yet available.

* Files in the 700 series contain data from telephone interviews held with respondents, while files in the 600 series contain data from telephone interviews held with proxies. In wave C however, the same questionnaire was used for both respondent and proxy; data was stored in the 600 series.
