- Studies that develop methods to better define clinical phenotypes, including sources of variability, in IDD, with particular focus on characteristic components of behavior and cognition; measurement tools to assess cognitive and behavioral development; tests that highlight abilities and disabilities, including tests for specific subpopulations (e.g., specific inborn errors of metabolism and syndromes such as Down, Fragile X, Prader-Willi, and Williams).
- Studies involving early interventions (biological, behavioral, educational, environmental) for infants born at risk for IDD; research into strategies for early intervention; follow-up of high-risk infants and children whose risk is due to biomedical conditions such as low birthweight and/or conditions of environmental deprivation; studies of intergenerational effects and outcomes for children whose parents have conditions associated with IDD; effects of teen pregnancy on at-risk infant outcome.

- Neurodevelopmental and longitudinal studies that characterize the neuropathogenesis and inherent variability in IDD to develop specific hypotheses about the initial (primary) abnormality, and to address the degree to which phenotypic variation impacts upon postnatal brain development.
- Studies to follow the developmental trajectories of different brain functions and their influence on developing cognitive and motor skills; such studies might use techniques of imaging, electrophysiology, pharmacology, molecular biology, and behavioral science.

- Studies of socio-ecological processes: individuals with IDD from various cultural and ethnic groups in multiple settings (naturalistic observation); ethnographic research, life history reporting, and systematic observation of specific activities.
- Studies of hyperaggressive, destructive, and self-injurious behavior in humans and animal models, including pharmacological and behavioral treatments; stereotypic behaviors; lack of adherence associated with IDD in family and educational settings.
- Studies of the epidemiology of IDD: analytic and case-control studies of etiology; incidence and prevalence; follow-up over the life span for outcomes.
- Studies that examine and evaluate behavior, life styles, health needs, and health disparities of affected individuals that could affect mortality and morbidity throughout the life span.
- Studies that develop and utilize assistive devices (e.g., computer software, hand-held devices, and touch screen computers) to help individuals with IDD to learn and communicate.
Requirements for IDDRC Users
To become a member of our Center, investigators (comprising faculty of The Children's Hospital of Philadelphia and the University of Pennsylvania) must have at least one NIH-funded research project in areas related to intellectual disabilities. The Center leadership determines if the project meets the IDDRC criteria and warrants the use of one or more core facilities. If the project is approved, the Center submits a recommendation to the Intellectual and Developmental Disabilities Research Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). Investigators who do not meet our eligibility requirements may still use our Core facilities as a non-member (at higher rates). For additional information, please access the Core sites.
Citing the Center and NIH Public Access Compliance
To support our ongoing funding, IDDRC members are expected to cite our Center (“Intellectual and Developmental Disabilities Research Center” - NIH/NICHD U54 HD086984) in all publications that result from work supported by one or more of our Core facilities.
The submission methods page of the NIH Public Access Policy website includes links to the following lists:
- Journals that automatically post NIH-supported papers to PMC (Method A)
- Journals and publishers that accept special arrangements from authors to post the paper directly to PMC (Method B)
- Publishers that will submit manuscripts to NIHMS (Method D)
Method C is when authors or their designee submit the manuscript to NIHMS. PDFs of step by step instructions with screen shots can be found here:
To associate a manuscript with an IDDRC Core in NIHMS, please use grant number U54HD086984 and search for the appropriate Core Director:
- Robert Schultz: Clinical Translational Core (Core B)
- Mary Putt: Biostatistics and Bioinformatics Core (Core C)
- Michael Robinson: Analytical Neurochemistry Core (Core D)
- Timothy Roberts: Neuroimaging and Neurocircuitry Core (Core E)
- Zhaolan (Joe) Zhou: Preclinical Models Core (Core F)
To apply for membership, please send the completed
application and your NIH biosketch (with 1-2 sentences in the personal statement about how your work is relevant to IDD) to the Center Administrator, Kristen Pidgeon, at
