Autism spectrum disorder, diagnostic disagreement in a developmental perspective


Considerably attention has been devoted to developing standardized methods for diagnosing autism. Research instruments such as ADI-R and ADOS-G have contributed to our knowledge regarding behavioral characteristics in preschool children. Both tools are considered as gold standard in diagnosing autism. However, in specific instances the instruments are over or under diagnosing autism and for these reasons it is established that using clinical diagnosis takes precedence in cases of disagreement. However little research has explored the characteristics of children for whom there are diagnostic disagreement, either between clinicians or between different diagnostic measures of autism. There is still little information about inter-rater reliability for diagnosing autism in young children. Forty-seven children (33 M:14 F) were recruited through the healthcare services in Oslo County. None had a diagnosis at the time of their assessment. 76.6 % were first met at the primary health care level and had not been evaluated by specialists earlier. The mean chronological age for the total sample was 27.0 months (sd=6.2), and the mean mental age (MA) was 13.2 months (sd=3.4). Data were collected during the children's evaluations and two clinicians made independent clinical diagnostic judgments of the children. The other clinician observed the administration of the ADOS and rated each child according to a checklist based on the DSM-IV criteria for Autism as well as scoring presence/absence of behaviors. The clinicians agreed in 88% of the children whether the child was within or outside the autism spectrum. The Corrected Kappa for expected value was 0.83 of 0.85 maximum possible. When comparing children within the autism spectrum, the clinicians agreed in 79.1% of the children concerning subgroups in the spectrum. The Corrected Kappa for expected value was 0.53 of maximum possible 0.89. The children with diagnostic disagreement had specific characteristics.
