Parent-teacher concordance for DSM-IV attention-deficit/hyperactivity disorder in a clinic-referred sample.

ABSTRACT

OBJECTIVE: To examine concordance between parent and teacher reports of DSM-IV attention-deficit/hyperactivity disorder (ADHD) and its symptoms. METHOD: Parents and teachers of 74 clinically referred children were interviewed using the ADHD module of the Diagnostic Interview Schedule for Children. Parent-teacher agreement for the diagnosis of ADHD and its subtypes, as defined in DSM-IV, as well as parent-teacher concordance of in-school ADHD symptoms, was examined. RESULTS: Agreement between parents and teachers was found to be relatively poor, with virtually no agreement for individual ADHD subtypes. Diagnoses based on either parent or teacher report frequently yielded a diagnosis of either inattentive or hyperactive-impulsive subtype of ADHD. However, when cross-informant data were used to form diagnoses, these subtypes became relatively rare, with most cases meeting criteria for ADHD combined type. In addition, parent reports of in-school behavior were more highly correlated with their own reports of their child's behavior at home than with teacher reports of their child's behavior in school. CONCLUSIONS: These data suggest that the diagnosis of ADHD inattentive or hyperactive-impulsive subtype based on data from a single informant may be of questionable validity, and they point to the importance of using multiple informants when diagnosing this disorder in clinically referred samples.
