National study of school psychologists’ use of evidence-based assessment in autism spectrum disorder. This framework provides confidence in the consistency of prevalence classifications of ASD and may be further applied to improve consistency of ASD diagnoses in clinical settings.Īiello, R., Ruble, L., & Esler, A. Classification of DSM-5 ASD by mapping specific exemplars from evaluation records by a diverse group of clinician raters is feasible and reliable. 60–.79 to excellent ≥ .80 Kappa values) across sex, race/ethnicity, and cognitive levels for both phases. Interrater reliability for each of the DSM-5 diagnostic categories and overall ASD classification was high (defined as very good. Clinicians applied the diagnostic exemplars to child behavioral descriptions in existing evaluation records to establish initial reliability standards and then for blinded clinician review in one site (phase 1) and for two ADDM Network surveillance years (phase 2). Clinicians completed an iterative process to map specific exemplars from the CDC Autism and Developmental Disabilities Monitoring (ADDM) Network criteria for ASD surveillance, DSM-5 text, and diagnostic assessments to each of the core DSM-5 ASD criteria. This means the categories of autistic disorder, Asperger’s disorder, and PDD-NOS will no longer be used-instead the diagnosis of ASD will be used.This paper describes a process to define a comprehensive list of exemplars for seven core Diagnostic and Statistical Manual (DSM) diagnostic criteria for autism spectrum disorder (ASD), and report on interrater reliability in applying these exemplars to determine ASD case classification. This change was made because research indicates the categories that were under PDD cannot be reliably distinguished. Additionally, the DSM-5 does not have any categories under ASD so all individuals meeting the diagnostic criteria will fall under one autism spectrum. In the DSM-5 the term ASD has replaced PDD. The fifth edition of the DSM was released in May 2014. In the DSM-IV, PDD included five types or categories: autistic disorder, Asperger’s disorder, childhood disintegrative disorder, Rett syndrome, and pervasive developmental disorder-not otherwise specified (PDD-NOS). PDD is the diagnostic classification in the DSM-IV (4th edition of the most widely used diagnostic manual of mental disorders). Are there different types of ASD?ĪSD used to be called Pervasive Developmental Disorder (PDD). The American Academy of Pediatrics recommends that all children be screened for ASD at 18 and 24 months of age. An experienced professional can diagnose ASD in toddlers as young as 18 to 24 months of age, but often ASD is not diagnosed until 3 to 5 years of age or later, after the window of opportunity for very early intervention. The second stage is a comprehensive diagnostic evaluation usually conducted by a multidisciplinary team that gathers information from an interview and structured observation.Įarly detection means earlier access to intervention. The first stage is screening, usually by doctors at well-child visits using validated screening checklists that parents fill out. The diagnosis can involve a two-stage process. These features include the absence of or delays in typical developmental milestones and the presence of unusual behaviors. The diagnosis is based on behavioral symptoms or features. Diagnosing ASD can be difficult because there are no blood or other medical tests.
