Cognitive functioning

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-J (K in progress) refer to the corresponding LASA-data files (e.g. ‘022‘ in column B-G refers to ‘LASAB022‘, ‘LASAC022‘, ‘LASAD022‘, ‘LASAE022‘, ‘LAS2B022‘, and ‘LASAG022‘ respectively).  Table entries are hyperlinks. Hovering  over the waves in the header will show the years in which the corresponding measurements took place.

For more details about the LASA-waves, see Design LASA.

Note that some of the data are not yet available (in red).

* 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.
