| Abstract: | Objective: To develop and evaluate an instrument to assess severity in anorexia nervosa (AN), the Clinician Administered Staging Instrument for Anorexia Nervosa (CASIAN). Method: Candidate items for the CASIAN were developed in three phases (domain, content, and item generation) followed by a pilot study. The psychometric properties of the resultant 34-item questionnaire were investigated in cross-sectional and longitudinal samples ( N = 171) with DSM-IV AN and subthreshold AN. Results: Item and factor analysis procedures resulted in a refined 23-item CASIAN comprising of six factors ('Motivation,' 'Weight,' 'Illness Duration,' 'Obsessionality,' 'Bulimic Behaviors,' and 'Acute Issues'). The CASIAN had high internal consistency (.811), test-retest (.957), and interrater reliability (.973). Preliminary support for the convergent, discriminant, concurrent, and predictive validity of the CASIAN was found. Discussion: The CASIAN is a psychometrically sound instrument. Further studies are needed to confirm the factor structure and assess its clinical and research utility. © 2011 by Wiley Periodicals, Inc. (Int J Eat Disord 2012) [ABSTRACT FROM AUTHOR] |
