Dataset: Interactive Autism Network (IAN)

Basic Information
Dataset Full Name Interactive Autism Network
Dataset Acronym IAN

The Interactive Autism Network (IAN) data is based on online surveys collected from a network of children and adults with autism spectrum disorder (ASD) and their families accessed through IAN web-based portals. Surveys are completed directly by either parents/caregivers of individuals with Autism, or adults with Autism. IAN participants are recruited primarily through social media, ASD related events, and networking between families of persons with ASD. Participants have the opportunity to complete baseline questionnaires, standardized instruments as well as one-time surveys. 

The IAN surveys collect a variety of data including items related to diagnosis, behavior, family, environment, and services received as well as special one-time topical surveys. Participating parents report on their child’s progress over time and adults with ASD share information about their experiences and needs. This approach provides researchers with a number of participant and participant proxy reported outcomes. 

IAN data serves as a research database as well as a research registry to help connect people with autism and their families to clinical research studies.  Based on the information that families and researchers provide, IAN works to match families to research studies recruiting around the country. 

Note: The IAN research registry closed on June 30, 2019 and are no longer enrolling participants or collecting new data. The de-identified data set is available to researchers on a limited basis (see data access below).
