Remarks
The National Institute of Mental Health Data Archive (NDA) is a collection of research data repositories including the National Database for Autism Research (NDAR), the Research Domain Criteria Database (RDoCdb), the National Database for Clinical Trials related to Mental Illness (NDCT), and the NIH Pediatric MRI Repository (PedsMRI). The NDA infrastructure was established initially to support NDAR, but has grown into an informatics platform that facilitates data sharing across all of mental health and other research communities.
