title: Parent and child contributions to diagnosis of mental disorder: are both informants always necessary?
abstract: OBJECTIVE
  To examine the unique cases contributed by parent and child informants to diagnostic classification, with the goal of identifying those diagnoses for which either or both informants are needed.
  
  
  METHODS
  The authors examined survey data from the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study, a 4-community epidemiology survey of 9- to 17-year-old children and their parents. Parent-child dyads (1,285 pairs) were independently interviewed by lay persons with the Diagnostic Interview Schedule for Children; a subset of these pairs (n = 247) were also interviewed by clinicians. Agreement between parents and children was examined with respect to levels of impairment, need for/use of services, and clinicians' diagnoses.
  
  
  RESULTS
  Parents and children rarely agreed on the presence of diagnostic conditions, regardless of diagnostic type. Nonetheless, most child-only- and parent-only-identified diagnoses were similarly related to impairment and clinical validation, with 2 exceptions: child-only-identified attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD).
  
  
  CONCLUSIONS
  Overall findings suggest that most "discrepant" diagnoses (those reported by one but not the other informant) reflect meaningful clinical conditions. In some instances, however, diagnoses reported by one but not the other informant should be treated with caution, as they may not reflect the full diagnostic condition (e.g., possibly child-only-identified ADHD or ODD). Further research is needed to determine the salience of child-only- or parent-only-reported cases.
