Dataset: The Autism Treatment Network Registry (ATN)

Basic Information
Dataset Full Name The Autism Treatment Network Registry
Dataset Acronym ATN

The Autism Treatment Network Registry (ATN) is a collaboration between Autism Speaks and a network of hospitals, physicians and researchers at 17 sites across the U.S and Canada. It is centered around clinical and health related research  and developed to improve care for children with autism spectrum disorder (ASD) and promote best practices in interdisciplinary medical care. Behavioral and medical data from the care and outcomes of children seen in the network facilities is stored in the registry database. The registry contains de-identified data aggregated across all sites on over 7,000 children diagnosed with ASD ages 2 – 17 ½ .

Although primarily cross sectional data the ATN also includes some longitudinal follow-up data for a subset of 672 consenting to participate in the Registry Call Back Assessment (RCBA) collected between 2015-2017. The RCBA included a battery of assessments designed to track the trajectory of major medical co-morbidities (sleep, GI distress, anxiety, hyperactivity and anthropometrics) and their relationships with behavioral and functional outcomes. RCBA data includes: physical exam, diagnoses and problems, medical and behavioral treatment, and behavioral, cognitive, and communication measures. RCBA data will become available on 1/18/2019.
