ABSTRACT
BACKGROUND: Emotion dysregulation is a transdiagnostic construct associated with multiple mental health conditions and shown to be an amenable target for treatment. The original Emotion Dysregulation Inventory (EDI) was created as a proxy-report measure validated in autistic and nonautistic youth. The goal of the current study was to develop a self-report version, the EDI-Self-Report (EDI-SR), that captures a first-person perspective and creates the option of multi-reporter measurement from adolescence through adulthood.
METHODS: Using methods developed by the Patient-Reported Outcomes Measurement Information System (PROMIS), potential items and response options were written and tested in cognitive interviews. Two samples (996 participants who are autistic or have other intellectual and developmental disabilities and 1,000 participants selected to be representative of the US census as a nonclinical comparison group) completed the initial item pool. Items were assessed using exploratory and confirmatory factor analyses, item response theory analyses, concurrent calibrations, convergent correlations with comparable legacy measures, internal consistency reliability, and test-retest reliability.
RESULTS: Exploratory factor analyses suggested splitting Reactivity and Dysphoria items for confirmatory factor analyses and subsequent analyses. Following analyses, a 25-item Reactivity scale, a 7-item Dysphoria scale, and a 6-item Reactivity short-form scale were finalized. EDI-SR subscales showed convergent validity and superior total information when compared with similar measures, strong internal consistency reliability, and good test-retest reliability.
CONCLUSIONS: The EDI-SR provides an efficient, precise measure of ED in autistic individuals, individuals with other intellectual and developmental disabilities, and a US census-matched representative sample, and allows for multi-reporter assessment in clinical and research contexts.
