Diagnostic and Statistical Manual of Mental Disorders, 5th Edition: DSM-5

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders, the taxonomic and diagnostic tool published by the American Psychiatric Association (APA). In the United States, the DSM serves as the principal authority for psychiatric diagnoses. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has practical importance. The DSM-5 is the only DSM to use an Arabic numeral instead of a Roman numeral in its title, as well as the only living document version of a DSM.

The DSM-5 is not a major revision of the DSM-IV-TR but there are significant differences. Changes in the DSM-5 include the reconceptualization of Asperger syndrome from a distinct disorder to an autism spectrum disorder; the elimination of subtypes of schizophrenia; the deletion of the “bereavement exclusion” for depressive disorders; the renaming of gender identity disorder to gender dysphoria; the inclusion of binge eating disorder as a discrete eating disorder; the renaming and reconceptualization of paraphilias, now called paraphilic disorders; the removal of the five-axis system; and the splitting of disorders not otherwise specified into other specified disorders and unspecified disorders.

Many authorities criticized the fifth edition both before and after it was published. Critics assert, for example, that many DSM-5 revisions or additions lack empirical support; inter-rater reliability is low for many disorders; several sections contain poorly written, confusing, or contradictory information; and the psychiatric drug industry may have unduly influenced the manual’s content, given many DSM-5 workgroup participants had ties to pharmaceutical companies.[2]

This new edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5), used by clinicians and researchers to diagnose and classify mental disorders, is the product of more than 10 years of effort by hundreds of international experts in all aspects of mental health. Their dedication and hard work have yielded an authoritative volume that defines and classifies mental disorders in order to improve diagnoses, treatment, and research. This manual, which creates a common language for clinicians involved in the diagnosis of mental disorders, includes concise and specific criteria intended to facilitate an objective assessment of symptom presentations in a variety of clinical settings inpatient, outpatient, partial hospital, consultation-liaison, clinical, private practice, and primary care.
