The DSM-5 reduces this triad to a dyad – impairment of social interaction and communication (now be regarded as one combined domain) and restricted repetitive and stereotyped patterns of behavior (Wing et al., 2011). The basic triad of impairments underlying Autism has included: impairment of social interaction, impairment of communication, and restricted repetitive and stereotyped patterns of behavior. The aim of the new DSM-5 is to improve diagnostic criteria that are not precise, such as combining subgroups of ASD and reducing diagnoses currently called “Not Otherwise Specified”. The DSM-IV-TR describes Pervasive Developmental Disorder (PDD) as a “diagnostic umbrella”, with five subtypes: 1) Autistic Disorder 2) Asperger’s Disorder 3) Rett’s Disorder 4) Childhood Disintegrative Disorder and 5) PDD-NOS (“Not-Otherwise-Specified”). The result of this process includes changes in the criteria for the diagnosis of Autism Spectrum Disorders (ASDs), and these changes have certainly evoked some questions, concerns and confusion among parents, professionals, and educators. The revision process also includes conducting extensive literature reviews, attending a series of planning conferences in partnership with the World Health Organization and the National Institutes of Health, and soliciting feedback from professionals and educators (APA, 2011 Wing, Gould, & Gillberg, 2011). From 2008-2010, the DSM-5 Task Force and Work Group members have examined the current edition (DSM-IV-TR) to determine:1) what components meet the needs of clinicians 2) what components do not meet the needs of clinicians and 3) how to address these needs (APA, 2011). Advances in neurology, genetics, and behavioral science have expanded our knowledge of identification, assessment, and treatment of individuals with mental health disorders.ĭSM revisions are the combined efforts of a work group comprised of clinical experts in various areas of diagnosis. Since the publication of DSM-I in 1952, a standard review process has led to revised DSM editions over the past two decades. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) debuted at the American Psychiatric Association (APA) annual meeting in May 2013.
