DSM-IV vs DSM-5 diagnostic criteria for toddlers with Autism

Abstract

The proposed DSM-5 will result in far fewer persons being diagnosed with ASD. These results replicate findings from two previous studies, with older children/adolescents and adults. As a result of these new criteria, far fewer people will qualify for needed autism services.

Application of the Final DSM-5 Criteria for Young Children with Autism Spectrum Disorder

“…For example, Matson et al [4] reported that 48% of toddlers with PDDs did not meet the new criterion, ASD. Several studies have also shown that a considerable percentage (8.8%~53.8%) of children with PDDs diagnoses did not meet ASD [2][3][4][5][6][7][8][9][10][11] (Table 3). Table 3: Characteristics of the previous studies *Reduction means the number (or rate) of cases who lost the ASD diagnosis in the draft or in relaxed rules.…”

“…Before the final version of DSM-5 was released in May 2013, several investigations with the proposed draft had been done [2][3][4][5][6][7][8][9][10][11]. These preliminary studies showed that a considerable percentage (8.8%~53.8%) of children with PDDs diagnoses did not meet the new criterion of ASD.…”

Autism assessment tools in the transition from DSM-IV to DSM-5

“…In a series of studies, using a variety of different diagnostic instruments and modalities, but neither ADI-R nor ADOS, Matson and colleagues showed 32 % of children [10] and 36 % of adults [11] with DSM-IV PDD did not meet the criteria for DSM-5 ASD. In a larger study on toddler with developmental disability, the same group measured a 47 % decrease in the diagnosis of a DSM-5 ASD compared to DSM-IV PDD group (24 % for the DSM-IV autistic disorder, and 88 % of the PDD-NOS) [12]. On the same sample the authors also showed that by relaxing the algorithm (i.e.…”

Transition from Pervasive Developmental Disorders to Autism Spectrum Disorder: Proposed Changes for the Upcoming DSM-5

“…[7,8,21] DSM-IV-TR'deki YGB tanı ölçütleri ile DSM-5'teki yeni otizm spektrum bozukluğu ölçütlerini karşılaştıran çalışmalar da, belirgin otizm belirtilerine sahip olmalarına karşın bazı çocuk ve ergenlerin yeni sisteme göre tanı alamayabileceğini göstermiş-tir. [16,22,23,24] DSM-5 Nörogelişimsel Bozukluklar Çalışma Grubu, bu araştırmaların bazılarını yöntemsel sınırlılıkları nedeniyle eleştirmiş ve yapıla-cak değişikliklerin otizm tanı ölçütlerinin özgüllüğünün yanı sıra duyarlılığını arttırmayı da hedeflediğini vurgulamıştır. [23,25] Yeni otizm spektrum bozukluğu tanısında toplumsal etkileşim ve iletişim güçlükleri alanlarının birleştirilmesine tamamen karşı çıkılmasa bile, bu deği-şikliğin konuşma ve dil ile ilgili sorunlara yetersiz ilgi gösterilmesi ile sonuçla-nabileceğine dair uyarılar olmuştur.…”
