Consulting on Harmonization of Survey Instruments

Social science surveys often collect data from similar samples or using similar survey designs, but in different countries or at different times. When combined, these data offer additional insights. When this is the goal, it is necessary to first harmonise the data in order to make them comparable with each other. We offer tailor-made advice on harmonising your data.

Our Consulting Services on Harmonization

Harmonization of Substantive Variables

How can we make data that was collected with different instruments comparable? We provide advise on the harmonization of substantive variables measured with different instruments, in particular in the following areas:

  • Assessing the comparability of different instruments
  • Assessing the consequences of lack of comparability
  • Harmonization of substantive variables measured with different instruments; especially latent constructs, such as values, attitudes, intentions, emotions, or personality traits

Harmonization of Socio-Structural Variables

In survey research, socio-structural varaibles are important evaluation criteria, as they make relevant social groups and thus the social structure of societies visible. We offer information and advice on the coding of socio-structural variables as well as on their harmonization across samples, e.g. for cross-national comparison. Our focus is on the measurement of education, occupational coding as well as the measurement of socio-cultural background.
