title: Interrater agreement for the schedule for affective disorders and schizophrenia epidemiological version for school-age children (K-SADS-E).
abstract: OBJECTIVE
  The main objective of this study was to assess the interrater agreement for the Schedule for Affective Disorders and Schizophrenia Epidemiological version for School-Age Children (K-SADS-E).
  
  
  METHODS
  Four interviewers being trained with the K-SADS-E scored independently 29 videotaped interviews performed with psychiatric outpatients in the ADHD Outpatient Clinic at Hospital de Clínicas de Porto Alegre. Interrater agreement analysis was performed using the kappa coefficient (k).
  
  
  RESULTS
  Kappa coefficients were.93 (p<.001) for affective disorders,.9 (p<.001) for anxiety disorders,.94 (p<.001) for attention-deficit/hyperactivity disorders and disruptive behavior disorders.
  
  
  CONCLUSIONS
  These findings suggest an excellent interrater agreement for the diagnosis of several mental disorders in childhood and adolescence by the Brazilian Portuguese version of the K-SADS-E.
