Path: Psychological Trauma, Step 1. This article places the DSM-5-TR criteria for posttraumatic stress disorder within the wider range of ways people may respond after trauma.

PTSD is one specific, clinically defined pattern that can follow trauma. Trauma-related effects can be broader. They may affect emotional, cognitive, physical, social, or day-to-day functioning without forming the exact pattern required for a PTSD diagnosis. The presence or absence of PTSD therefore does not, by itself, describe the full impact of an experience.

In trauma-informed contexts, trauma concerns an event or set of circumstances, how it is experienced, and its effects. PTSD is a particular diagnosis with a defined exposure requirement, symptom pattern, duration threshold, functional-impact requirement, and exclusion criterion.

Many people have strong stress reactions after trauma and improve over time. Some develop PTSD. Others may experience different or subthreshold difficulties, including depression, anxiety, substance-related problems, grief, sleep disruption, physical stress reactions, or changes in relationships and daily functioning. Not meeting every PTSD criterion does not mean that distress is unimportant, and exposure to trauma does not make PTSD inevitable.

Scope of this summary

The criteria below apply to adults, adolescents, and children older than six. DSM-5-TR provides a separate, developmentally adapted criteria set for children six years and younger. A PTSD diagnosis requires all of Criteria A through H, including the stated symptom thresholds.

This is a learner-friendly paraphrase, not the copyrighted diagnostic text and not a self-scoring instrument.

Criterion A: Qualifying traumatic exposure

There must be exposure to actual or threatened death, serious injury, or sexual violence through at least one of these routes:

  • Directly experiencing the event.
  • Witnessing the event in person as it happened to someone else.
  • Learning that such an event happened to a close family member or close friend. When actual or threatened death is involved, it must have been violent or accidental.
  • Repeated or extreme exposure to distressing details of traumatic events, commonly through professional duties. Exposure through media does not ordinarily qualify unless it is work-related.

Criterion A is the exposure gate for this particular diagnosis. It should not be treated as a universal definition of every experience that may be understood as traumatic in trauma-informed practice.

Criterion B: Intrusion symptoms

At least one trauma-related intrusion symptom beginning after the event:

  • Involuntary, distressing memories.
  • Distressing dreams related to the event.
  • Dissociative re-experiencing, such as flashbacks.
  • Intense or prolonged psychological distress when encountering reminders.
  • Marked bodily reactions to reminders.

Criterion C: Avoidance

At least one persistent form of avoidance:

  • Avoiding memories, thoughts, or feelings connected with the event.
  • Avoiding external reminders, such as people, places, conversations, activities, objects, or situations.

Criterion D: Negative changes in cognition and mood

At least two changes beginning or worsening after the event:

  • Difficulty remembering an important part of the event, typically because of dissociative amnesia rather than head injury, alcohol, or drugs.
  • Persistent, exaggerated negative beliefs or expectations about oneself, other people, or the world.
  • Persistent, distorted blame of oneself or others for the event or its consequences.
  • A persistent negative emotional state.
  • Markedly reduced interest or participation in important activities.
  • Feeling detached or estranged from others.
  • Persistent difficulty experiencing positive emotions.

Criterion E: Changes in arousal and reactivity

At least two changes beginning or worsening after the event:

  • Irritability, angry outbursts, or aggression.
  • Reckless or self-destructive behavior.
  • Hypervigilance.
  • An exaggerated startle response.
  • Difficulty concentrating.
  • Sleep disturbance.

Criterion F: Duration

The pattern represented by Criteria B through E lasts for more than one month.

Criterion G: Clinical significance

The disturbance causes clinically significant distress or interferes with social life, work, or another important area of functioning.

Criterion H: Exclusion

The disturbance is not attributable to a substance, medication, or another medical condition.

What the criteria do and do not tell us

These criteria answer a specific diagnostic question: whether a person's presentation fits the DSM-5-TR pattern called PTSD. They do not measure the full seriousness, meaning, or impact of an experience, and they do not determine whether distress deserves recognition or support.

People can experience substantial trauma-related difficulties without meeting every PTSD threshold. Reactions differ between people and may change over time. A symptom list also cannot establish the diagnosis on its own. Assessment requires clinical judgment, differential diagnosis, developmental and cultural context, and consideration of other possible explanations.

Additional DSM-5-TR specifiers

After the full PTSD criteria are met, clinicians may specify with dissociative symptoms when persistent or recurrent depersonalization or derealization is present. They may specify with delayed expression when the full criteria are not met until at least six months after the event, although some symptoms may begin earlier.

Educational boundary

This article is an educational summary, not a screening or diagnostic tool. DSM-5-TR criteria are intended to be applied with clinical judgment by appropriately trained and authorized professionals. If trauma-related reactions are persistent, distressing, or interfering with daily life, consider consulting a qualified mental-health professional. In an immediate safety crisis, contact the appropriate local emergency or crisis service.
