The necessity for multiple sources of information including skilled clinical observation and reports from parents/caregivers/teachers is highlighted by the need to meet a higher proportion of criteria. Requiring two symptom manifestations for repetitive behavior and fixated interests improves specificity of the criterion without significant decrements in sensitivity. Secondary data analyses were conducted on social/communication symptoms to determine most sensitive and specific clusters of symptoms and criteria descriptions for a range of ages and language levels.Merging social and communication domains requires new approach to criteria.In DSM-IV, multiple criteria assess same symptom and therefore carry excessive weight in making diagnosis.Several social/communication criteria were merged and streamlined to clarify diagnostic requirements. Decision based on literature review, expert consultations, and workgroup discussions confirmed by the results of secondary analyses of data from CPEA and STAART, University of Michigan, Simons Simplex Collection databases.Providing examples for subdomains for a range of chronological ages and language levels increases sensitivity across severity levels from mild to more severe, while maintaining specificity with just two domains.Requiring both criteria to be completely fulfilled improves specificity of diagnosis without impairing sensitivity.Delays in language are not unique nor universal in ASD and are more accurately considered as a factor that influences the clinical symptoms of ASD, rather than defining the ASD diagnosis.Deficits in communication and social behaviors are inseparable and more accurately considered as a single set of symptoms with contextual and environmental specificities.Fixated interests and repetitive behaviors.Because autism is defined by a common set of behaviors, it is best represented as a single diagnostic category that is adapted to the individual's clinical presentation by inclusion of clinical specifiers (e.g., severity, verbal abilities and others) and associated features (e.g., known genetic disorders, epilepsy, intellectual disability and others.) A single spectrum disorder is a better reflection of the state of knowledge about pathology and clinical presentation previously, the criteria were equivalent to trying to "cleave meatloaf at the joints".Differentiation of autism spectrum disorder from typical development and other "nonspectrum" disorders is done reliably and with validity while distinctions among disorders have been found to be inconsistent over time, variable across sites and often associated with severity, language level or intelligence rather than features of the disorder.New name for category, autism spectrum disorder, which includes autistic disorder (autism), Asperger's disorder, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified. Symptoms must be present in early childhood (but may not become fully manifest until social demands exceed limited capacities)
Excessive adherence to routines and ritualized patterns of behavior.Stereotyped motor or verbal behaviors, or unusual sensory behaviors.Restricted, repetitive patterns of behavior, interests, and activities, as manifested by at least TWO of the following: Failure to develop and maintain peer relationships appropriate to developmental level.Marked deficits in nonverbal and verbal communication used for social interaction:.Proposed revisions Autism Spectrum DisorderĬlinically significant, persistent deficits in social communication and interactions, as manifest by all of the following: Please continue to check this site for updates to criteria and for more information about the development process. We thank you for your interest in DSM-5 and hope that you use this opportunity not only to learn more about the proposed changes in DSM-5, but also about its history, its impact, and its developers. As part of the development process, the preliminary draft revisions to the current diagnostic criteria for psychiatric diagnoses are now available for public review.
