title: Psychometric properties of the clinical impairment assessment: norms for young adult women.
abstract: OBJECTIVE
  This study aimed to investigate the initial psychometric properties and to establish norms for the Clinical Impairment Assessment (CIA v. 3.0) among a nonclinical sample of young adult women.
  
  
  METHODS
  The CIA is a brief, 16-item self-report measure designed to assess psychosocial impairment due to eating disorder features over the past 28 days. We administered the CIA and the Eating Disorder Examination-Questionnaire (EDE-Q v. 6.0) to 438 university women (mean age = 25 years).
  
  
  RESULTS
  Participants' mean global CIA score was 6.4 (SD = 7.5; range 0-40). Acceptable levels of internal consistency (Cronbach's alpha = 0.94) and 1-week test-retest reliability were observed. Significant correlations were found between the CIA and the EDE-Q total and subscale scores (Spearman rhos = 0.58-0.79), indicating that greater levels of impairment were associated with higher levels of eating disorder psychopathology.
  
  
  CONCLUSIONS
  Results demonstrated satisfactory psychometric properties of the CIA among a sample of young adult women, suggesting the utility of the CIA to measure impairment due to eating disorder features in nonclinical samples.
