Clinical Deterioration Assessment in Eating Disorders Test - Symptoms and Signs
This brief self-report measure is used to evaluate psychosocial impairment associated with eating disorder symptoms. The Clinical Deterioration Assessment in Eating Disorders helps characterize the extent to which symptoms interfere with day-to-day functioning across relevant life domains.
The instrument contains 16 items and typically takes about 3 minutes to complete. Items assess perceived impact on emotional well-being, cognitive functioning, and social and interpersonal functioning. Scores are commonly used to support clinical formulation and to monitor change over time; the measure is not designed to establish a diagnosis. The Clinical Deterioration Assessment in Eating Disorders was developed by Bohn and Fairburn.
