IAN Research offers de-identified data to qualified researchers on a limited basis. Please note that there is a cost for these services. In addition, IAN provides a code book (see links below).

IAN Research has more than 54,000 consented participants. A variety of data about individuals with ASD, siblings, and parents was 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.
