Objective: To screen and create a list of adult volunteers in good health for participation in research studies conducted at the National Institutes of Health (NIH) in Bethesda, Maryland. Develop a normative set of structural and functional brain MRI scans that are linked to healthy research volunteer characteristics. Maximize scientific impact of data from volunteers by broadly sharing with other researchers.

Study Population: Adult males and females in general good health who are 18 years of age and older.

Design: Adult individuals who are interested in participating in NIMH IRP clinical studies as a healthy research volunteer can directly visit or be directed to visit the study website where they will first consent electronically and then complete a set of online self-report measures. Items may include: demographic information, mental health symptoms, disability status, substance use patterns, handedness and clinical/family history. Individuals who are flagged based on predetermined responses to survey items will be further screened by a member of the study clinical team. If found to be ineligible for the study because of a clinically significant or unstable medical or mental health condition, these individuals will be referred back to the community and/or given information about NIMH clinical studies for which they may be eligible. Respondents with no flags or who pass through additional screening will be scheduled for an in-person assessment. During the outpatient appointment and after in-person informed consent, participants will receive a brief clinical interview to screen for current medical and mental conditions, and risk for self-harm. They will complete assessments of psychological, emotional, physiologic, biological and cognitive functioning. Participants will undergo a physical exam and be asked to provide blood and urine samples for routine clinical labs as well as additional blood samples for future secondary analysis that could include genetic or biomarker assays. Participants can separately consent for an optional baseline brain magnetic resonance imaging (MRI) scan and an optional magnetoencephalography (MEG) exam. All consent forms will explicitly inform participants that if enrolled in the study, their de-identified data will be broadly and publicly shared through NIH-approved data repositories. Participants in this recruitment and characterization study will then be placed on a list of healthy research volunteers from which other NIMH IRP studies may recruit according to the inclusion and exclusion criteria in their respective IRB-approved protocols.

Outcome Measures: Outcome measures may include demographic data, mental and medical history and symptoms, results of psychological, emotional, physiologic, biological, and cognitive testing, physical exam and MRI findings.
