Thank you for your interest in research at UNC.

Welcome Researchers

The purpose of this page is to provide information to researchers about Core services and how to access them.

Who We Are

The Research Participant Registry (RPR) Core is a research unit within the Carolina Institute for Developmental Disabilities (CIDD) . The RPR Core supports research projects on developmental disabilities at UNC. The Core has four registries:

The Child Development Registry is a Triangle-area registry (NC counties: Wake, Durham, Chatham, Orange, and Alamance) of typically developing infants and children. Investigators can use this registry to recruit participants and age matched control subjects, and to pilot test assessment measures and protocols.

The UNC Autism Registry is a state-wide registry of children and adults with autism spectrum disorders.

The Fragile X Registry is a national registry of children and adults with FXS.

Intellectual and Developmental Disorders Registry is a registry of adults and children with specific syndromes such as Angelman, Down, Prader-Willi, Rett, Turner, Williams, and others. It also includes individuals with developmental delay, ADHD, communication delay and intellectual disabilities.

For approved/registered researchers, the Registry can assist with recruitment, public relations and referral source development, and grant preparation.  Please refer to the Policies and Procedures document for more information.

Services Provided by the Core

The RPR Core is available to approved Intellectual and Developmental Disabilities Research Center (IDDRC) researchers to recruit participants for their research.

We accomplish this by:

  • Contacting potential participants from the three active registries;
  • Assisting with grant preparation, providing fee estimates for core services, a sample description, a letter of support, and consultation on recruitment strategies and materials;
  • Advertising studies at conferences, presentations, and community referral sites;
  • Disseminating research findings to registry members and the public.

Using the Core

UNC researchers who have been approved for IDDRC membership are eligible to access core services. Contact Dr. Gabriel Dichter to inquire.

The time to apply for access to the RPR Core is during grant preparation. Researchers must have approval from the Core Director before writing the Registry into a grant proposal. The registries are in high demand, and access is prioritized by the funding source (NIH being highest) and date of service request to the RPR Core.

Complete the Registry Service Request Form

How can I get access to research participants?

What information is available in the Registry about participants?

Each of the three registries have contact information and limited demographic information for individuals or parents of children. The Autism and FXS registries also have diagnostic/medical confirmation of ASD or FXS diagnosis. This information is confidential and used only to determine eligibility for studies. It cannot be released to research projects.

What does it cost?

Fees are necessary to support the cost of maintaining the registries. The Director will send information about rates when he receives your Service Request form.

When does my access to the Registry expire?

Permission to recruit from the Registry is granted for a specific project/study for the duration of that project. 

How do I get matched with potential participants?

The Registry manager will conduct a query of the database and send referrals for your study.  We will forward reply forms from individuals who want to participate.

If my study is longitudinal, will families be asked to participate in other research projects through the Registry?

Families who are participating in a research study will not be contacted for another study until their participation in the first study has ended to prevent negatively affecting data collected for either study. Exceptions may be made with the consent of the PI.

What do I need to communicate to my IRB if I want to use the Registry?

Reference the Registry as a recruitment source in your IRB application. The Registry is reviewed and approved by the UNC IRB, Study #01-0843 and Study #07-0279.

What do I have to report after recruiting participants from the Registry?

You will provide monthly updates of the participants' status in your study including whether they enrolled or declined, were excluded and why, consented to participate, and when they completed the study.  You are also responsible for providing a summary of your study's findings to each participant.

Can I ask families permission for my research project to contact them again in the future?

The Consent Agreement with Registry participants specifies that they will be contacted by the Registry so that they may accept or decline to participate confidentially.  You may request that participants give permission to be contacted again, but you may not contact them again yourself before checking their availability with the Registry manager. Research participants are a shared resource, and some participants may not be re-contacted for various reasons (e.g., they are involved in another study, they decline to participate in your study).
