DSM-5 Criteria for PTSD Explained

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the standard mental health diagnostic reference used by clinicians worldwide. The DSM-5 was released in 2013, and a revised version called DSM-5-TR (Text Revision) was published in 2022. The VA uses DSM-5-TR criteria to evaluate PTSD claims as of 2026.

Understanding the 8 diagnostic criteria for PTSD (labeled A through H) helps veterans understand what evidence supports their claim, what symptoms to discuss with mental health providers, and how the C&P examiner evaluates eligibility.

01
DSM-5-TR Overview

The DSM-5-TR (Text Revision) is the current diagnostic standard used by mental health professionals to diagnose mental disorders. The original DSM-5 was published in 2013; the TR revision was published in March 2022 and reflects updated diagnostic criteria, clinical descriptions, and research evidence.

For PTSD specifically, DSM-5-TR maintains the core 8-criterion structure introduced in DSM-5, with refinements to clinical descriptions and minor updates to symptom specifications.

The VA officially incorporated DSM-5 criteria into the rating regulations, replacing the older DSM-IV criteria. Compensation and Pension examinations, treatment records, and rating decisions all rely on DSM-5-TR for PTSD diagnoses.

02
Criterion A, Exposure to Trauma

Criterion A requires exposure to actual or threatened death, serious injury, or sexual violence in one or more of the following ways:

• Directly experiencing the traumatic event: Combat, attack, accident, assault
• Witnessing in person the event as it occurred to others: Seeing injury, death, attack on others
• Learning that the event occurred to a close family member or close friend: Violent or accidental death applies
• Experiencing repeated or extreme exposure to aversive details of the event: Common for first responders, medics, mortuary personnel

Note: Witnessing through media (TV, news) does not generally qualify unless work-related (such as professional duties involving exposure to such media). The trauma must be sufficiently severe; not all stressful events qualify.

For VA claims, Criterion A corresponds to the in-service stressor requirement. Combat exposure, MST, and other documented service-related trauma typically satisfy Criterion A.

03
Criterion B, Intrusion Symptoms

Criterion B requires one or more intrusion symptoms associated with the traumatic event, beginning after the event:

• Recurrent, involuntary, intrusive distressing memories of the event
• Recurrent distressing dreams related to the event
• Dissociative reactions (flashbacks) in which the person feels or acts as if the event were recurring
• Intense or prolonged psychological distress at exposure to internal or external cues that symbolize or resemble the event
• Marked physiological reactions to internal or external cues that symbolize or resemble the event

These are the "re-experiencing" symptoms most people associate with PTSD: nightmares, flashbacks, intrusive memories.

04
Criterion C, Avoidance

Criterion C requires persistent avoidance of stimuli associated with the traumatic event, beginning after the event, as evidenced by one or both of:

• Avoidance of, or efforts to avoid, distressing memories, thoughts, or feelings about or closely associated with the traumatic event
• Avoidance of, or efforts to avoid, external reminders (people, places, conversations, activities, objects, situations) that arouse distressing memories, thoughts, or feelings about or closely associated with the traumatic event

Avoidance is often a defining feature of PTSD. Veterans avoid news coverage of war, refuse to discuss service, avoid people or places that remind them of the event, or avoid emotional experiences entirely.

05
Criterion D, Negative Cognitions and Mood

Criterion D requires two or more negative alterations in cognitions and mood associated with the traumatic event:

• Inability to remember important aspects of the traumatic event (typically due to dissociative amnesia, not head injury or substances)
• Persistent and exaggerated negative beliefs about oneself, others, or the world
• Persistent, distorted cognitions about the cause or consequences of the event leading to blame of self or others
• Persistent negative emotional state (fear, horror, anger, guilt, shame)
• Markedly diminished interest or participation in significant activities
• Feelings of detachment or estrangement from others
• Persistent inability to experience positive emotions

These criteria added in DSM-5 reflect the broader emotional and cognitive impact of PTSD that DSM-IV captured less directly. Many veterans with PTSD experience these symptoms but did not previously identify them as PTSD-related.

06
Criterion E, Arousal and Reactivity

Criterion E requires two or more marked alterations in arousal and reactivity associated with the traumatic event, beginning or worsening after the event:

• Irritable behavior and angry outbursts (with little or no provocation) typically expressed as verbal or physical aggression toward people or objects
• Reckless or self-destructive behavior
• Hypervigilance
• Exaggerated startle response
• Problems with concentration
• Sleep disturbance

These "hyperarousal" symptoms are central to PTSD. Hypervigilance, exaggerated startle, and sleep disturbance are particularly common in veterans.

07
Criterion F, Duration

Criterion F requires that the duration of disturbance (the symptoms from criteria B, C, D, and E) is more than 1 month.

This duration requirement distinguishes PTSD from Acute Stress Disorder (ASD), which has the same symptoms but lasts less than 1 month. ASD is a diagnosis sometimes given shortly after a traumatic event; if symptoms persist beyond 1 month, the diagnosis is updated to PTSD.

For VA claims, the 1-month duration must be clearly documented. Treatment records over 1+ months establish the criterion.

08
Criterion G, Functional Impairment

Criterion G requires that the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

This criterion ensures PTSD reflects genuine functional impact, not just symptoms in isolation. For VA rating purposes, the severity of this functional impairment determines the rating percentage under 38 CFR § 4.130.

09
Criterion H, Not Due to Other Causes

Criterion H requires that the disturbance is not attributable to the physiological effects of a substance (e.g., medication, alcohol) or another medical condition.

The diagnosing clinician must rule out other causes that could explain the symptoms. Substance use, TBI, mood disorders, and other conditions are considered. PTSD diagnosis is appropriate when the symptoms exceed what would be expected from these other causes.

Note: PTSD can coexist with substance use disorders and other conditions; Criterion H ensures the PTSD symptoms are not simply explained by another cause.

10
DSM-IV vs DSM-5 Changes

DSM-5 made important changes from DSM-IV that affect PTSD diagnosis:

• Removed the requirement that the response involve intense fear, helplessness, or horror (DSM-IV Criterion A2). The current criterion is based on the nature of the trauma exposure, not the emotional response
• Reorganized the criteria into 4 symptom clusters (intrusion, avoidance, negative cognitions/mood, arousal/reactivity) instead of 3
• Added the criterion of negative cognitions and mood (Criterion D)
• Expanded the list of intrusion symptoms
• Added avoidance as a separate criterion from numbing
• Added the "dissociative subtype" of PTSD for individuals with prominent depersonalization or derealization symptoms
• Created separate criteria for PTSD in children 6 years and younger

For veterans previously diagnosed under DSM-IV, the DSM-5-TR re-evaluation may identify additional symptoms (particularly under Criterion D) that were not previously recognized as PTSD-related.

11
How the VA Applies DSM-5-TR

The VA uses DSM-5-TR criteria in compensation and pension contexts:

• C&P examinations: Examiners use DSM-5-TR criteria to confirm PTSD diagnosis
• Disability Benefits Questionnaires (DBQs): PTSD DBQs are organized around DSM-5-TR criteria
• Treatment records: VA treatment records reference DSM-5-TR diagnoses
• Rating decisions: Rating decisions discuss whether DSM-5-TR criteria are met
• Service connection determinations: The in-service stressor (Criterion A) is documented separately, but the other criteria are met by current clinical evidence

For veterans pursuing PTSD claims, ensure your treating provider documents each of the 8 criteria specifically. A nexus letter or DBQ that addresses each criterion strengthens the claim significantly.
