Core Study Questionnaire
TSS conducts a recurrent core survey to collect basic socio-demographic, behavioral, and attitudinal information across various fields of research. The core questionnaire aims to make this information available to the scientific community and prevent commissioned questionnaires from repeating basic questions (e.g., education level and media consumption).
