About IAN Research Data

IAN Research offers de-identified data to qualified research studies throughout the world. In addition, IAN provides a code book and phone and email support. Please note that there is a cost for these services.

IAN Research now has more than 54,000 consented participants. A variety of data about individuals with ASD, siblings, and parents is gathered through a series of online questionnaires. Some of these questionnaires are standardized, such as the Social Responsiveness Scale, while others on topics such as pregnancy, treatments, and parental depression are developed in partnership with subject matter experts.
