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.
