Problems with comparability of existing survey data

  • Survey questions on the same topic (e.g. happiness or life satisfaction) often differ in response format (e.g. a 3-point or a 5-point scale). This complicates comparison across surveys and over time; a large body of incomparable data has gathered dust in the archives of survey agencies.
  • Survey studies often have different language versions, e.g. the World Values Survey uses questionnaires in 50 different languages. This language variation also complicates comparison: will the response option 4 ‘pretty happy’ on a 5-point scale for English speaking respondents be the same as for Chinese respondents ticking the same option 4 labelled as:  相当快乐 in their questionnaire?

At the Erasmus University Rotterdam, we have developed two new techniques for scale homogenization. We did this in the context of comparative happiness research, but the techniques are also applicable for other fields of research, such as survey studies on health or political attitudes.
