title: The use of the GBI in a population of adolescent offspring of parents with a bipolar disorder.
abstract: OBJECTIVE
  To assess the psychometric properties and the usefulness of the General Behavior Inventory (GBI) in the adolescent age range.
  
  
  METHODS
  The GBI, the Schedule for Affective Disorders and Schizophrenia for School Age Children, Kiddie-SADS-Present and Lifetime Version (K-SADS-PL) and the Youth Self-Report (YSR) were used to assess 117 adolescents of a bipolar parent twice with an interval of 14 months. Based on the K-SADS results, the bipolar offspring were assigned to one of three groups: with mood disorders, with non-mood disorders, and with no disorders.
  
  
  RESULTS
  Principal component analyses resulted in the same two-factor solution as reported for adults. The Depression scale of the GBI discriminated between adolescents with a DSM-IV mood disorder, a non-mood disorder and no disorder on Axis I. Significant correlations between GBI scales and the corresponding Internalizing and Externalizing scales of the YSR showed convergent validity.
  
  
  CONCLUSIONS
  The GBI can be used in the adolescent age range as a self-report to discriminate mood disorders from non-mood disorders or no disorders.
