- Abstract
We conducted 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 (SCD). For 33 included studies, use of DSM-5 criteria suggests decreases in diagnosis for ASD [20.8% (16.0–26.7), p < 0.001], DSM-IV-TR Autistic Disorder [10.1% (6.2–16.0), p < 0.001], and Asperger's [23.3% (12.9–38.5), p = 0.001]; pervasive developmental disorder-not otherwise specified decrease was not significant [46.1% (34.6–58.0), p = 0.52]. Less than one-third [28.8% (13.9–50.5), p = 0.06] of individuals diagnosed with DSM-IV-TR but not DSM-5 ASD would qualify for SCD. Findings suggest smaller decreases in ASD diagnoses compared to earlier reviews. Future research is needed as concerns remain for impaired individuals without a diagnosis.
