Data source

In the first three lidA study waves (2011, 2014, 2018), participants were interviewed about their work and health in their own homes in a computer-assisted interview (CAPI). In the fourth wave (2022/23), due to the pandemic, the surveys were conducted either by a computer-assisted interview (CAPI) in their home or by a computer-assisted interview by phone (CAPI by phone). They also received a questionnaire about their current attitude towards life, which they could complete themselves. A hand grip test was additionally carried out in waves 1 and 2.

If the interviewee agreed, data linkage from external data sources was possible (see contents below). Each data source requires written consent.

- Individual administrative data from the German Federal Employment Agency was linked* in all waves.

- Individual data from the statutory pension insurance was included in waves 3 and 4*.

- Furthermore, data from the respective health insurances was linked* to the survey data on an individual basis in waves 1 and 2.

* In each case, only with written consent.

Survey data from wave 1 and 2 (reduced version without the individual data provided by Federal Employment Agency and by the health insurances) is available as a Scientific Use File for interested researchers at the Forschungsdatenzentrum FDZ (Research Data Centre) of the Federal Employment Agency of the IAB since 2016.
