Documentation of the BASE-II Data

The BASE-II data are documented in a codebook. This is intended to be used as an instrument to assist researchers who would like to apply for the use of BASE-II data for a specific research project.

The codebook (with the original items partly in German) provides an overview of the variables available in BASE-II for which you can apply. To access the codebook please contact the members of the specific research units or the coordinator of the study (see contact details on the right).

 

Applying for the Use of BASE-II Data

You can apply for BASE-II data in the following way (Please find the documents in the box on the right):

  1. Application: The application comprises an abstract, a working plan, and the required variables. It is advisable to ensure that you contact and inform all project partners involved before you hand in the application form. The application is the basis for the contract and the BASE-II Steering Committee needs to agree on it. ([1] Application).
  2. Data protection policy: Because the BASE-II Data are not completely anonymized you need to deliver a data protection policy in which you describe the storing and usage of the data. It needs to be signed by the data protection officer of your research unit/institution. For advice you can contact the data protection coordinator of the Max Planck Institute for Human Development, Thomas Feg, who can check your protection statement beforehand. An information sheet on data protection is provided, which explains which information you need to include in a data protection policy ([2] Information sheet in data protection).
  3. Data protection statement: All users of BASE-II data have to send a signed data protection statement to us ([3] Data Protection Form).
  4. Contract: If all conditions are  fullfilled a contract regarding the data transfer will be drawn up by BASE-II ([4] Data Transfer Contract).

BASE-II Publication Requirements

Please use the BASE-II publication list on this website to find out which topics have already been worked on.

For all publications it is necessary to include the following reference:

“This article [poster, presentation, report] uses data from the Berlin Aging Study II (BASE-II) which has been supported by the German Federal Ministry of Education and Research under grant numbers 16SV5537/16SV5837/16SV5538/16SV5536K/01UW0808/01UW0706. The Responsibility for the contents of this publication lies with its author[s].”

If possible the following BASE-II publications should be mentioned in the metholodical part of the publication:
