DSM-5 Guide: Categories, Diagnostic Criteria, and How It's Used

This is the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), the official international manual which mental health professionals in the U.S. use to diagnose mental disorders. The manual was last updated in 2013 by the American Psychiatric Association, as the DSM-5-TR (Text Revision). It has 22 categories of disorders and standardized diagnostic criteria. The DSM-5 is the official guidebook for the federal government on diagnosing and reporting mental health issues, and it is used by clinicians, researchers, and insurance companies.

What Is the DSM-5?

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA) in May 2013, is the fifth edition of the manual. It is the common guide to diagnosing mental health disorders in the USA. Every known mental disorder is listed in the manual with the symptoms, length of time they have to be present and the conditions that have to be met to arrive at a diagnosis.

Let's take a look at the DSM-5. The latest edition is the DSM-5-TR (Text Revision), which was released in March 2022. There are 22 categories of mental disorders, and about 300 specific diagnoses. The DSM-5-TR introduced the new Prolonged Grief Disorder and updated more than 70 sets of criteria with clarifications. The U.S. federal government recognizes the DSM-5-TR as its official manual for diagnosing and reporting mental disorders, per the National Board for Certified Counselors. The manual is used by clinicians along with ICD-10-CM codes for insurance billing.

For more than 70 years the DSM has been the most influential diagnostic tool in psychiatry. In 1952 the first edition was published. The categories and criteria are updated on the basis of the latest research in each new edition. To get mental wellness tools and self-care tips, visit August AI.

DSM-5 vs DSM-5-TR: What Changed?

The DSM-5-TR is not a new version! It is a text revision of the DSM-5, akin to the way in which the DSM-IV-TR was a text revision of the DSM-IV. APA Publishing published the TR on March 18, 2022.

The most significant difference in the DSM-5 TR from the earlier versions is the inclusion of a new disorder—Prolonged Grief Disorder (PGD)—in Section II. A new diagnosis is one that is used for individuals who have experienced the death of someone close for at least 12 months and who have been dealing with a persistent, pervasive grief, which is causing clinically significant distress. Some of the signs are strong desire, emotional suffering, significant decrease in emotional experiences and problems with adapting to everyday life.

Other DSM-5 TR changes documented by the Annals of Indian Psychiatry include:

• Over 70 modified diagnostic criteria sets with clarifications

• New symptom codes for suicidal behavior and nonsuicidal self-injury

• Updated ICD-10-CM codes throughout the manual

• Revised text descriptions based on a literature review since 2010

• Refined definitions of attenuated forms of delusion, hallucination, and disorganized speech

• Updated language to avoid implying relationships (e.g., "in the context of relationship with an individual with prominent delusions")

The APA also publishes online supplements (September 2022, September 2023, September 2024) to keep the manual current between major revisions. The online version is considered the authoritative version at any given time, per editor Michael B. First, MD.

The 22 DSM-5 Categories of Mental Disorders

The DSM 5 categories organize mental disorders into 22 chapters. Each chapter groups related conditions to help clinicians compare and differentiate similar disorders.

1. Neurodevelopmental Disorders (e.g., autism spectrum disorder, ADHD)

2. Schizophrenia Spectrum and Other Psychotic Disorders

3. Bipolar and Related Disorders

4. Depressive Disorders (e.g., major depressive disorder, persistent depressive disorder)

5. Anxiety Disorders (e.g., generalized anxiety disorder, panic disorder)

6. Obsessive-Compulsive and Related Disorders

7. Trauma- and Stressor-Related Disorders (e.g., PTSD, Prolonged Grief Disorder)

8. Dissociative Disorders

9. Somatic Symptom and Related Disorders

10. Feeding and Eating Disorders (e.g., anorexia nervosa, bulimia nervosa, binge-eating disorder)

11. Elimination Disorders

12. Sleep-Wake Disorders

13. Sexual Dysfunctions

14. Gender Dysphoria

15. Disruptive, Impulse-Control, and Conduct Disorders

16. Substance-Related and Addictive Disorders

17. Neurocognitive Disorders (e.g., dementia, delirium)

18. Personality Disorders (e.g., borderline, narcissistic, antisocial)

19. Paraphilic Disorders

20. Other Mental Disorders

21. Medication-Induced Movement Disorders and Other Adverse Effects of Medication

22. Other Conditions That May Be a Focus of Clinical Attention

These DSM 5 categories make it easier for clinicians to think through differential diagnosis: ruling out similar conditions before settling on the most accurate diagnosis. Each category contains specific disorders with their own symptom criteria.

How DSM-5 Diagnostic Criteria Work

DSM 5 diagnostic criteria follow a consistent structure for each disorder. To meet criteria for a diagnosis, a person must show specific symptoms for a specific duration, with those symptoms causing clinically significant distress or impairment in important areas of functioning.

A typical diagnostic entry includes:

• A. Symptom criteria. The specific symptoms, often presented as a list with a minimum number required (e.g., "5 of 9 symptoms" for Major Depressive Disorder).

• B. Duration requirement. How long symptoms must persist (e.g., at least 2 weeks for depression, 6 months for generalized anxiety).

• C. Impairment requirement. The symptoms must cause significant distress or impair social, occupational, or other important functioning.

• D. Exclusion criteria. Symptoms cannot be better explained by another condition, substance use, or medical issue.

• Specifiers. Additional codes for severity (mild, moderate, severe) and features (e.g., "with anxious distress").

For Major Depressive Disorder, for example, a person must have 5 of 9 listed symptoms (including either depressed mood or loss of interest) for at least 2 weeks. The symptoms must cause significant distress or impairment and cannot be explained by substance use, medication, or another medical condition. These DSM 5 diagnostic criteria standards help different clinicians arrive at consistent diagnoses for the same patient.

DSM-5 vs ICD-11: Two Systems, Different Uses

The DSM 5 vs ICD 11 question matters because both systems classify mental disorders, but they serve different purposes. The DSM-5-TR is published by the American Psychiatric Association. The ICD-11 is published by the World Health Organization and came into effect on January 1, 2022.

A 2021 World Psychiatry analysis by First and colleagues found substantial overlap but meaningful differences. The two systems compared 104 diagnostic entities. The researchers rated 20 disorders (19.2%) as having major differences, 42 disorders (40.4%) as having minor differences, 10 disorders (9.6%) with minor differences due to greater DSM-5 specification, and 31 disorders (29.8%) as essentially identical.

Key DSM 5 vs ICD 11 differences include:

• Functional impairment. The DSM-5 requires functional impairment as a diagnostic criterion. The ICD-11 does not always require it.

• Categories. 19 ICD-11 disorder categories do not appear in DSM-5; 7 DSM-5 categories do not appear in ICD-11.

• New ICD-11 categories. Complex PTSD, prolonged grief disorder, gaming disorder, and compulsive sexual behavior disorder were introduced in ICD-11.

• Geographic use. The DSM-5 dominates U.S. clinical practice; the ICD-11 is used globally for health statistics and billing in most other countries.

The two systems are now closer than at any time since the ICD-8 and DSM-II, per Psychiatric Times. Differences are largely based on differing priorities and interpretations of the same evidence.

How Psychologists Use DSM-5 in Practice

Understanding how psychologists use DSM 5 helps explain why the manual matters. Clinicians use it daily for several purposes.

Diagnostic assessment. Psychologists, psychiatrists, social workers, and counselors use DSM-5 criteria to evaluate symptoms during clinical interviews. Standardized criteria help different clinicians reach consistent conclusions about the same patient.

Treatment planning. The evidence-based treatments will vary depending on the diagnosis. If a clinician believes that a client has major depression disorder, he or she might try cognitive behavioral therapy, interpersonal therapy, or antidepressants. DBT may be indicated by a diagnosis of borderline personality disorder.

Insurance and billing. U.S. insurance companies need a DSM-5 diagnosis (ICD-10-CM code) in order to authorize mental health treatment. This renders the DSM-5 a critical tool in clinical practice for the U.S. health care system.

Communication. A DSM-5 diagnosis provides a common language to clinicians for discussing cases. If the patient is treated by several providers, the diagnosis aids in keeping everyone on the same page.

Research. The populations reported in this research are defined according to the criteria of the DSM-5. This means that research even on generalized anxiety disorder is being conducted with the same kind of people.

The DSM-5 is also used for forensic evaluations, disability determinations, and educational planning by mental health professionals. Clinicians use the manual along with their clinical judgment, life context, and treatment goals.

Limitations and Critiques of DSM-5

The DSM-5 has faced criticism since its 2013 release. Some critics say that it relies on symptom checklists which may overlook the reasons for mental distress. Other examples indicate that diagnostic categories might vary from edition to edition due to committee decisions and not necessarily new biological evidence.

A shared issue: many diseases have similar symptoms which make it hard to make a clean diagnosis. A large number of people suffer from more than one disorder at the same time (comorbidity).

Some of the criticisms were taken up by including text on cultural factors, sex/gender, suicide risk, and prevalence by group at the end of the DSM-5-TR. The basic categorical model, however, remains. In certain aspects, the ICD-11 has progressed toward a more dimensional approach, some researchers believe to be more clinically relevant.
