title: Attention problems versus conduct problems as six-year predictors of problem scores in a national sample.
abstract: OBJECTIVE
  To test the extent to which attention problems, the continuation of early comorbid conduct problems, and overall initial problems account for poor outcome scores on the Child Behavior Checklist and related measures 3 and 6 years after initial assessment.
  
  
  METHODS
  The course of attention and conduct problems was investigated in a nationally representative US sample assessed three times over 6 years, using standardized ratings of attention, conduct, and other problems and gender-specific scores for defining deviance.
  
  
  RESULTS
  Subjects deviant on both attention and conduct problems scored significantly higher on behavior problems at outcome than did those deviant on only attention problems or conduct problems. After controlling for initial conduct problems, initial attention problems made little unique contribution to later conduct problems. Predictive patterns were similar across gender and age groups.
  
  
  CONCLUSIONS
  Both boys and girls who show a combination of attention and conduct problems are at particular risk for the persistence of conduct problems.
