For the research master course on Structural Equation Modeling, students formed groups and theorized about factor structures in short questionnaires. After “pre-registering” all theorized models, they now need to collect data. Your help in answering these questionnaires is very much appreciated! Each questionnaire is 9 – 12 items so it should not take long. Please fill in all questionnaires, or take a random sample of questionnaires to fill in!
