The emotion dysregulation inventory: Psychometric properties and item response theory calibration in an autism spectrum disorder sample.

This paper describes a new measure of poor emotional control called the Emotion Dysregulation Inventory (EDI). Caregivers of 1,755 youth with ASD completed candidate items, and advanced statistical techniques were applied to identify the best final items. The EDI is unique because it captures common emotional problems in ASD and is appropriate for both nonverbal and verbal youth. It is an efficient and sensitive measure for use in clinical assessments, monitoring, and research with youth with ASD.
