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

Abstract: A growing body of research has raised concerns about the number of individuals diagnosed with autism spectrum disorder (ASD) according to DSM-IV-TR who may no longer qualify for diagnoses under the new DSM-5 criteria, published in May 2013. The current study systematically reviews 25 articles evaluating samples according to both DSM-IV-TR and DSM-5 ASD criteria. Consistent with previous reviews, the majority of included studies indicated between 50 and 75% of individuals will maintain diagnoses. We conducted v… Show more

“…Children with more subtle ASD, with less well-defined or ambiguous features, are more likely to present at an older age or during adolescence to other services in Singapore instead. This is consistent with findings from other studies raising concerns that the DSM-5 is less likely to be confirmatory for ASD in those with Asperger's disorder or a higher cognitive ability (IQ C 70) (McPartland et al 2012;Taheri and Perry 2012;Smith et al 2015;Volkmar and Reichow 2013;Mattila et al 2011). Even so, it is argued that a diagnostic criteria need to function well for all subtypes, age and presentations of individuals with a given disorder.…”

“…In a recent systematic review conducted by Smith et al (2015), majority of the included literature reported that between 50 to 75 % of individuals with ASD will maintain the diagnosis. The decrease in ASD diagnosis from DSM-IV-TR to DSM-5 occurred most for individuals with Asperger's disorder or PDD-NOS, and this pattern was consistent across age bands of below 5, 6-10 years, and above 11 years old for the individuals included in the study.…”

“…In contrast, almost all (92 %) children with a DSM-IV diagnosis of autistic disorder had a DSM-5 ASD diagnosis. Consistently, Smith et al (2015) reported in a systematic review that in half of the studies less than 25 % of the children with PDD-NOS met DSM-5 criteria for ASD, whereas rates were much higher for children with an autistic disorder. Compared to children with an ASD diagnosis according to both the DSM-IV and DSM-5, children with a DSM-IV ASD diagnosis who did not meet DSM-5 ASD criteria were characterized by relatively low levels of RRB symptoms and milder levels of social communication impairment in our study.…”

“…The pattern of elevations in withdrawn behaviors, thought, and social problems was distinct from that seen in youth with BD, but similar to that observed in other ASD cohorts. 17,33 The impact of revisions to diagnostic criteria (of ASD and other disorders) in DSM-5 on these findings may warrant future attention 34 . Second, this study did not explore or control for effects related to ADHD comorbidity.…”
