Fehldiagnose Aufmerksamkeitsdefizit- und Hyperaktivitätssyndrom?: Empirische Befunde zur Frage der Überdiagnostizierung

Abstract

Although it is assumed both by healthcare professionals as well as by public opinion that attention deficit hyperactivity disorder (ADHD) is widely overdiagnosed, so far there is little empirical evidence to support this presumption. However, the presented study shows clear evidence for an overdiagnosis of ADHD. Furthermore, the data demonstrate that based on identical symptoms, boys more often receive a diagnosis for ADHD than girls. A false ADHD diagnosis also correlates with a recommendation for medical and psychotherapeutic treatment. One explanation for misdiagnosis is the fact that therapists in the course of diagnosis, as with other everyday decision-making processes, are influenced by heuristics. The most common heuristics that can lead to misdiagnosis are the representativeness heuristic and the availability heuristic. Such mistakes could be avoided by clearly following diagnostic criteria and the use of structural interviews. © 2012 Springer-Verlag.
