To help us protect participant privacy, we have obtained a Certificate of Confidentiality from the National Institutes of Health. The researchers can use this Certificate to legally refuse to disclose information that may identify a participant in any federal, state, or local civil, criminal, administrative, legislative, or other proceedings, for example, if there is a court subpoena. The researchers will use the Certificate to resist any demands for information that would identify a partcipant. There is one exception to the promise of confidentiality: if we see or are told that someone is planning to harm themselves or someone else, we will disclose this information to the proper authorities.
