title: Mother and teacher reports of ADHD symptoms: DSM-IV Questionnaire data.
abstract: OBJECTIVE
  Diagnosis of attention-deficit/hyperactivity disorder (ADHD) is thought to be best accomplished by a multimodal approach. In many research and clinical settings, such extensive procedures may not be feasible. A screening instrument that could identify children meeting necessary (but not sufficient) criteria would permit selection of subgroups for more resource-intensive diagnostic procedures.
  
  
  METHODS
  The Diagnostic Rating Scale (DRS) was completed by the mothers and teachers of 124 children referred to hospital-based clinics and 225 nonreferred children. The authors performed principal components analysis (PCA) on the questionnaire, compared the scores obtained by children from the 2 samples, and examined age and gender effects. Diagnoses derived from the DRS were not validated against structured diagnostic interviews.
  
  
  RESULTS
  PCAs replicated the DSM-IV symptom combinations. Children from the referred sample exhibited more symptoms (p < .001) than children from the community sample. Boys were overrepresented among the children who received DRS-derived ADHD diagnoses. Girls were more likely (92%) to receive a diagnosis of ADHD, predominantly inattentive subtype, than other ADHD diagnoses.
  
  
  CONCLUSIONS
  The results of this study provide preliminary support for the validity of the parent and teacher DRS as time- and resource-efficient screening instruments for examining symptoms associated with ADHD.
