The request form for ethical clearance (EASHW dual use committee University Antwerp, 'aanvraagformulier), the original methodology ('protocol') as well as appendix 1 to 5 submitted together with the request and, finally, the letter containing the ethical clearance itself.
We refer the reader specifically to appendix 3: debriefing statement of the study. As the study cannot disclose its subject initially it is very important to inform them afterwards as much as possible about the actual status of Tourette Syndrome research.
