Frequently Asked Questions

What happens after I complete the online surveys?

Study staff will review the responses and may call you to clarify responses or ask additional questions. If you are eligible to participate in the next phase of the study and are in the Washington, D.C. metro area, you will be contacted to schedule a clinical assessment visit.

What will happen in the clinical assessment visit?

The outpatient visit will take place at the NIH Clinical Center in Bethesda, MD and last approximately 2 hours. You will be asked to consent to the clinical assessment and consider the optional MRI or MEG. The visit will include psychological and cognitive assessments, a mental health evaluation, a physical exam, and blood and urine tests. Following the clinic visit, you will be notified if you are eligible to be included on the list of healthy research volunteers. You could later elect to have an optional brain scan (MRI) and/or optional MEG, and can learn about additional NIMH study opportunities. Participation is voluntary. You can opt-out of the study at any time.

Additional travel information will be provided after scheduling your in-person appointment. One component of the clinical assessment, the mental health evaluation, may be conducted via telehealth.

What does it cost to participate?

The study is free and study procedures are provided at no cost. Participants will be compensated for each component of the clinical assessment.

Is the study confidential?

Yes, all questionnaire responses, data, and study information are confidential and secure. The data collected for this study has no personal identifiable information.

Can I participate in other NIMH studies?
