title: Eating disorder symptom severity scale: a new clinician rated measure.
abstract: This study describes the development and validation of the clinician-rated Eating Disorder Symptom Severity Scale (EDS(3)), created to address a gap in measurement options for youth with eating disorders. The EDS(3) is modeled on the Childhood Severity and Acuity of Psychiatric Illness Scales (Lyons, J. S, 1998). Factor analysis revealed a 5-factor solution and accounted for 78% of the variance, and internal consistency within the subscales was good (Cronbach alphas: 0.69 to 0.93). The EDS(3) is a valid and reliable measure designed for clinicians to help assess the severity of a youth's eating disorder and to facilitate outcomes research.
