Abstract:
The Eating Disorder Inventory-2 (EDI-2) and Bulimia Test-Revised (BULIT-R) have demonstrated strong reliability and validity in college students and adults. Although used in adolescent samples, little is known about the psychometric properties of these measures for adolescents. The reliability, factor structure, and mean levels of five EDI-2 scales and the BULIT-R were evaluated over 3 years. Data were collected yearly from two samples of adolescent females, one recruited from three public middle schools (n = 239, mean baseline age = 12.8) and one from two public high schools (n = 119, mean baseline age = 15.9). Results provide strong evidence for the reliability and stability of these measures. Mean levels of both measures appeared remarkably consistent over the 3 years. These results provide evidence of good psychometric performance for these scales in adolescence. The lack of change in these measures raises questions about the developmental trajectory of these variables through adolescence.
