title: Study IV: concurrent validity of the DSM-IV revised Children's Interview for Psychiatric Syndromes (ChIPS).
abstract: OBJECTIVE
  To determine validity of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) revised Children's Interview for Psychiatric Syndromes (ChIPS) in inpatient children and adolescents.
  
  
  METHODS
  Participants were 47 psychiatric inpatients 6-12 (n = 23) and 12 to 18 years of age (n = 24). ChIPS was administered to all participants. The Diagnostic Interview for Children and Adolescents-Revised-Child Version (DICA-R-C) was administered to 40 participants. Discharge diagnoses were recorded for all participants. Kappas, low base rate kappas, and percentage agreement were used to assess diagnostic agreement between sources for 18 disorders.
  
  
  RESULTS
  ChIPS/DICA-R-C kappas could not be calculated for two disorders because of 100% agreement on their absence. Fourteen of 16 kappas were significant (p < 0.05). The remaining 2 of 16 disorders had 98% agreement (kappax = 0.494, p < 0.157). When ChIPS results were compared with discharge diagnoses, sensitivity for each disorder averaged 70%, whereas specificity averaged 84%. When disagreements occurred between all three sources, ChIPS was somewhat more likely than DICA-R-C to agree with discharge diagnoses (27% versus 22%). Analysis were repeated for children and adolescents, then for boys and girls. Boys and children had fewer significant ChIPS and DICA-R-C kappa coefficients compared with girls and adolescents; this appeared to be related to the fewer number of diagnoses they endorsed. ChIPS/clinician agreement was similar for boys and girls as well as for children and adolescents. Administration time was less for ChIPS than for DICA-R-C (p < 0.08).
  
  
  CONCLUSIONS
  Psychometric properties of the DSM-IV revised ChIPS compare favorably with that of other structured interviews. ChIPS appears to work well for adolescents as well as children.
