We investigate how good survey questions about different topics are, across different countries and languages. We particularly focus on estimating the measurement quality of survey questions (defined as the product of reliability and validity) by means of Multitrait-Multimethod (MTMM) experiments. Thus, we design and implement such MTMM experiments in several surveys, such as the European Social Survey, the Gesis Panel, the Norwegian Citizen Panel and many more. Data from these experiments are analysed using advanced structural equation models. Results are used to provide guidelines about how to best formulate survey questions in different contexts, but also to correct for the remaining measurement errors. Furthermore, we also investigate how to best design, estimate and test the fit of MTMM experiments.
Moreover, we do research on how to predict the measurement quality of survey question based on the question characteristics. This research has led to the Survey Quality Predictor (SQP) software, a free license online software that can predict the measurement quality of questions in more than 20 languages. We maintain and improve SQP constantly, by developing new features of the software, redefining the characteristics that are used for predictions, testing different methods of meta-analyses, etc. SQP is an ongoing research project in which anyone interested can collaborate.
