title: Validity and limitations of the Brazilian version of the Composite International Diagnostic Interview (CIDI 2.1).
abstract: OBJECTIVE
  To study the concurrent validity of the Brazilian Composite International Diagnostic Interview 2.1 using as gold standard the clinical diagnoses based on the ICD-10 criteria and the Longitudinal, Expert, All Data (LEAD) procedure.
  
  
  METHODS
  The sample was composed of 185 subjects selected at psychiatric hospitals, psychiatric outpatient units, the community, and primary care services. These individuals were intentionally selected according to 9 diagnostic groups.
  
  
  METHODS
  Composite International Diagnostic Interview (CIDI-core) version 2.1 (paper-and-pencil) administered by 16 trained interviewers.
  
  
  METHODS
  concurrent validity of diagnoses of the Composite International Diagnostic Interview 12-month.
  
  
  RESULTS
  Values found for sensitivity and specificity in each diagnosis were: alcohol-related disorders (79.5%/97.2%); psychoactive substance-related disorders (77.3%/100%); schizophrenia and other psychotic disorders (28.6%/93.9%); manic episode and bipolar affective disorder (38.9%/96.4%); depressive disorder (82.5%/ 93.8%); phobic-anxiety disorder (80.6%/93.5%); obsessive-compulsive disorder (18.2%/98.9%); somatoform disorder (41.7%/90.8%); eating disorder (45.5%/100.0%).
  
  
  CONCLUSIONS
  The Composite International Diagnostic Interview proved to be valid for diagnoses of alcohol-related disorders, psychoactive substance-related disorders, depressive disorder and phobic-anxiety disorder. The probable explanations for the poor performance for the other diagnoses were: necessity of some clinical judgement by the lay interviewer; difficulty to use the Probe Flow Chart; interviewees' difficulty of understanding; and lack of mechanisms to certify the veracity of the information.
