The new edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5®) 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.
Used by clinicians and researchers to diagnose and classify mental disorders, the criteria are concise and explicit, 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.
New features and enhancements make DSM-5® easier to use across all settings. Learn more about some of the new organization and features of the DSM-5 and the diagnostic differences between DSM-IV-TR and DSM-5 below.

For further clinical evaluation and research, the APA is offering a number of “emerging measures” in Section III of DSM-5. These patient assessment measures were developed to be administered at the initial patient interview and to monitor treatment progress, thus serving to advance the use of initial symptomatic status and patient reported outcome (PRO) information, as well as the use of “anchored” severity assessment instruments. Instructions, scoring information, and interpretation guidelines are included. Clinicians and researchers may provide APA with feedback on the instruments’ usefulness in characterizing patient status and improving patient care.
