Study Summary
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. Participants can separately consent for an optional baseline brain magnetic resonance imaging (M
