We conducted a systematic review and meta-analysis to determine the effect of changes to the Diagnostic and Statistical Manual (DSM)-5 on autism spectrum disorder (ASD) and explore policy implications. We identified 418 studies; 14 met inclusion criteria. Studies consistently reported decreases in ASD diagnosis (range 7.3–68.4 %) using DSM-5 criteria. There were statistically significant pooled decreases in ASD [31 % (20–44), p = 0.006] and DSM-IV-TR subgroups of Autistic disorder [22 % (16–29… 

How has DSM-5 Affected Autism Diagnosis? A 5-Year Follow-Up Systematic Literature Review and Meta-analysis

A 5-year follow-up systematic review and meta-analysis to determine change in frequency of autism spectrum disorder (ASD) diagnosis since diagnostic and statistical manual 5 (DSM-5) publication and explore the impact of Social Communication Disorder suggests smaller decreases in ASD diagnoses compared to earlier reviews.

Comparing Diagnostic Outcomes of Autism Spectrum Disorder Using DSM-IV-TR and DSM-5 Criteria

Testing the psychometric properties of the DSM-5 model and determined how well it performed across different gender, IQ, and DSM-IV-TR sub-type revealed good model fit across gender and IQ.

The Effects of DSM-5 Criteria on Number of Individuals Diagnosed with Autism Spectrum Disorder: A Systematic Review

Visual analyses of subgroups using harvest plots found the greatest decreases among high-functioning populations with IQs over 70 and/or previous diagnoses of PDD-NOS or Asperger’s disorder.

DSM-5 Changes and the Prevalence of Parent-Reported Autism Spectrum Symptoms in Fragile X Syndrome

Assessment of parent-reported autism symptomology in fragile X syndrome suggests the importance of subthreshold SCI symptoms for individuals with FXS in ASD diagnoses, and Relaxing the social communication criteria by one symptom count led to a threefold increase in those meeting criteria for ASD.

An evaluation of the clinical application of the DSM-5 for the diagnosis of autism spectrum disorder

This paper reviews the major changes to diagnostic criteria from DSM-IV-TR to DSM-5 and emphasizes how these changes are hypothesized to impact prevalence rates, as well as trends in characteristics of individuals who would have met previous criteria for ASD but no longer qualify for a diagnosis under DSM- 5.

Comparison of DSM-IV-TR and DSM-5 Criteria in Diagnosing Autism Spectrum Disorders in Singapore

The DSM-IV-TR performed slightly better than DSM-5 when applied concurrently against the best estimate clinical diagnoses for 110 children referred for diagnostic assessments of Autism Spectrum Disorder in a Singaporean outpatient speciality clinic, and more participants with a PDD-NOSbest estimate clinical diagnosis were misclassified on DSM- 5.

A Meta-analysis of DSM-5 Autism Diagnoses in Relation to DSM-IV and DSM-IV-TR

This appears to be the first meta-analysis study which has incorporated articles on the percentage of people with a Diagnostic and Statistical Manual of Mental Disorders-Forth Edition (DSM-IV) autism

How well are DSM-5 diagnostic criteria for ASD represented in standardized diagnostic instruments?

Differences in interpretation of DSM-5 criteria provide a challenge for symptom operationalization which will be most effectively overcome by consensus, testing and reformulation.

Brief Report: Investigating the Implications of Applying the New DSM-5 Criteria for Diagnosing Autism Spectrum Disorder in a Preschool Population in Singapore

The overall concordance rate of ASD diagnosis on the DSM-IV-TR and DSM-5 was higher than that reported in other studies.



Brief Report: Comparability of DSM-IV and DSM-5 ASD Research Samples

Utilizing combined ADOS/ADI-R data, 93 % of participants met DSM-5 criteria, which suggests likely continuity between DSM-IV and DSM- 5 research samples characterized with these instruments in combination.

Exploring the Proposed DSM-5 Criteria in a Clinical Sample

Concerns are raised that the new DSM-5 criteria for Autism Spectrum Disorder may miss a number of children who would currently receive a diagnosis, who had significantly lower levels of cognitive and adaptive skills and greater autism severity but were similar in age.

Comparison of ICD-10R, DSM-IV-TR and DSM-5 in an Adult Autism Spectrum Disorder Diagnostic Clinic

Investigation of whether ASD diagnostic outcome varied when DSM-5 was used compared to ICD-10R and DSM-IV-TR in a clinical sample of 150 intellectually able adults found reduced rates of ASD diagnosis may mean some ASD individuals will be unable to access clinical services.

A comparison of diagnostic criteria on the Autism Spectrum Disorder Observation for Children (ASD-OC)

Many children who are currently diagnosed with ASD may no longer be diagnosed, despite having significant impairments roughly equal to those who meet DSM-5 criteria.

Brief Report: An Exploratory Study Comparing Diagnostic Outcomes for Autism Spectrum Disorders Under DSM-IV-TR with the Proposed DSM-5 Revision

Of the 111 participants who received an ASD diagnosis under DSM-IV-TR, 26 did not meet DSM-5 criteria, and the majority of these had received a DSM- IV-TR PDD-NOS diagnosis.

Diagnostic procedures in autism spectrum disorders: a systematic literature review

A systematic review addressing the accuracy, reliability, validity and utility of reported diagnostic tools and assessments for autism spectrum disorders revealed levels of accuracy very similar to the correct classification rates for the current ‘gold standard’ diagnostic procedure.
