ATTENTION EUROPEAN UNION (EU) RESIDENTS:

Effective May 2018, the General Data Protection Rules (GDPR) apply to participants who are currently residing in EU countries. Our legal team continues to evaluate how to best comply with GDPR; at this time, we have been advised to limit contact with EU residents for data collection. Thus, if you are a current EU resident, you should not proceed any further. Later, if the legal team provides final guidance for GDPR compliance that involves contact with EU residents, you will be contacted.

Questionnaire responses will remain strictly confidential and will be used only for medical statistical purposes. For further information on confidentiality and privacy, please click here.
If you have any questions, please click here to send us an e-mail or send an email to us directly at guts@channing.harvard.edu or call us at (617) 525-2279, 9am-4pm Eastern time.
