Current danger takes priority

Ongoing abuse, severe dissociation with loss of safety or suicidal intent may make an ordinary therapy session unsafe.

Action: Assess the immediate threat, establish a safety plan and arrange emergency or safeguarding intervention where necessary before proceeding with trauma-memory processing.

Purpose and principles

Select trauma-focused psychological treatment using age, symptom burden, elapsed time and trauma context, while preserving safety, consent and appropriate therapeutic pacing.

Trauma-focused treatment addresses the persistent sense of current threat associated with intrusive memories, avoidance, heightened arousal and altered trauma-related meanings. A traumatic experience may be remembered as if it is occurring now, and reminders can trigger intense bodily and emotional responses. Avoidance can limit opportunities to update those meanings or reconnect with ordinary life. Assessment should nevertheless distinguish post-traumatic symptoms from ongoing external danger. A person who remains at risk from an assailant needs practical protection as well as psychological treatment.

Trauma-focused CBT is a family of validated interventions, including cognitive therapy for PTSD, cognitive processing therapy, prolonged exposure and narrative exposure therapy. The specific manual guides memory processing and work on meanings such as guilt, shame, loss or anger. Treatment also includes psychoeducation, strategies for arousal and flashbacks, safety planning, reduction of avoidance and restoration of social or occupational functioning. It is delivered by trained practitioners with continuing supervision. Discussing a traumatic event supportively is different from delivering the complete intervention.

Key points

  • Do not routinely require a detailed trauma narrative in an initial general clinical consultation; establish needs, safety and willingness to discuss the event.
  • For adults with acute stress disorder or clinically important PTSD symptoms within the first month, NICE recommends individual trauma-focused CBT.
  • Offer individual trauma-focused CBT to adults with PTSD or clinically important symptoms presenting more than one month after trauma.
  • Consider EMDR at one to three months after non-combat trauma if the adult prefers it, and offer EMDR beyond three months after non-combat trauma.
  • Adult trauma-focused CBT and EMDR usually involve eight to twelve sessions; more may be needed after multiple traumas.
  • For children aged seven to seventeen, consider EMDR beyond three months only if they do not respond to or engage with trauma-focused CBT.
  • Do not offer psychologically focused debriefing to prevent or treat PTSD.

Indications, selection and cautions

Intrusions and present threat

Nightmares, flashbacks or intense reactions to reminders may make a past event feel current, with avoidance and hypervigilance restricting everyday functioning.

Trauma-related meanings

Persistent beliefs about guilt, permanent damage or universal danger can maintain distress; explore their personal meaning without forcing premature detailed disclosure.

Dissociation during contact

Detachment, blank periods or loss of orientation may require grounding, a slower pace and specialist assessment of how safely the person can remain engaged.

Developmental presentation

Children may show trauma-related play, behavioural change, sleep disturbance or separation difficulties rather than a fluent adult account of intrusive memories.

Continuing exposure

Unsafe accommodation, coercion or repeated traumatic events can sustain symptoms and must be addressed in the formulation and immediate support plan.

Red flags requiring action

  • Disclosure of ongoing violence or an immediate threat to a child or vulnerable adult requires an appropriate safeguarding response alongside trauma treatment.

Assessment before treatment

  1. 01
    Trauma and symptom assessmentFirst step
    Why
    Establish clinically important symptoms, functional impact and relevant event timing.
    Interpretation and limitations
    Ask sensitively about the event category, when it occurred and current difficulties; a detailed forensic narrative is not necessary to identify treatment and safety needs.
  2. 02
    Risk and safeguarding review
    Why
    Identify current danger, self-harm risk and responsibilities towards dependants.
    Interpretation and limitations
    Separate memory-triggered alarm from a continuing threat while taking both seriously; explain limits of confidentiality and agree a plan appropriate to the actual risk.
  3. 03
    Comorbidity and engagement assessment
    Why
    Recognise depression, substance misuse, dissociation and barriers to treatment.
    Interpretation and limitations
    Determine what needs concurrent or prior treatment and what can be managed within trauma therapy; avoid blanket exclusion based solely on a comorbid diagnosis.
  4. 04
    Baseline outcome and preference review
    Why
    Choose an acceptable intervention and track changes meaningful to the person.
    Interpretation and limitations
    Use an appropriate validated PTSD measure alongside sleep, relationships and daily functioning, and discuss the practical demands and timing-specific evidence for available therapies.

Treatment approach

01Adult treatmentApply the time-specific recommendationFirst stepAn adult reports PTSD or clinically important post-traumatic symptoms after assessment of immediate needs.+
  1. 1Offer trauma-focused CBT for acute stress disorder or clinically important symptoms within one month, and for PTSD or clinically important symptoms presenting beyond one month.
  2. 2PreferredFor non-combat trauma, discuss EMDR as a consideration at one to three months when preferred and as an offered option beyond three months.
  3. 3Arrange treatment with a trained supervised practitioner using a validated manual, usually over eight to twelve sessions and longer when the formulation indicates additional need.
02Child pathwayUse developmentally appropriate trauma careA child or young person has persistent clinically important symptoms after a traumatic event.+

Complications, monitoring and follow-up

  • Check distress and orientation before ending a session, and ensure the person understands their agreed grounding and between-session support plan.
  • Track nightmares, avoidance and functional restrictions as well as questionnaire change, because improvement may occur unevenly across symptom domains.
  • Review self-harm, suicidality and continuing exposure whenever circumstances change or trauma work reveals a previously unrecognised threat.
  • Ask whether the treatment pace and target memories remain acceptable, distinguishing expected transient distress from sustained deterioration that requires reformulation.
  • Plan for anniversaries, treatment endings and future reminders, including how to seek renewed help if intrusive symptoms begin limiting life again.

Special situations

Debriefing is not early treatment

A prescribed psychologically focused debriefing session is not equivalent to a validated trauma-focused intervention offered to someone with clinically important symptoms.

EMDR includes preparation

Self-calming, target selection, phased processing and review are essential parts of the intervention; isolated eye movements do not establish protocol fidelity.

Avoid blanket stabilisation delays

Practical safety and engagement work should answer specific needs, with review of when trauma treatment can proceed rather than indefinite postponement.

Trauma type qualifies recommendations

The NICE adult EMDR timing recommendations specify non-combat trauma, so they should not be presented as identical universal rules for every exposure.

Common pitfalls

  1. 01

    Offering compulsory detailed retelling immediately after trauma as though psychologically focused debriefing prevents PTSD.

  2. 02

    Describing EMDR as the routine initial therapy for every traumatised child without the age, timing and prior CBT qualifications.

  3. 03

    Treating a flashback-management technique as a substitute for a complete evidence-based trauma treatment.

  4. 04

    Overlooking current abuse because all fear is attributed to a past traumatic memory.

Authoring stateComplete draftClinical stateAwaiting reviewJurisdictionUnited Kingdom
Eye movement desensitisation and reprocessing is delivered in phases. The therapist establishes preparation and self-calming skills, identifies target memories and associated beliefs, and uses repeated bilateral stimulation while the person engages with the target. Eye movements are usual, but taps or tones may be appropriate or preferred, including for visual impairment. The purpose is to reduce the distress attached to the memory and develop more adaptive beliefs, with review of remaining triggers and future coping. EMDR should follow a validated manual; bilateral stimulation alone is not a complete treatment.

Timing and population change the NICE recommendation. An adult with acute stress disorder or clinically important PTSD symptoms within one month should be offered individual trauma-focused CBT. Beyond one month, offer individual trauma-focused CBT for PTSD or clinically important symptoms. For non-combat-related trauma, consider EMDR between one and three months if the adult prefers it, and offer it after three months. Both adult interventions typically involve eight to twelve sessions, with additional sessions for clinical need such as multiple traumatic exposures. These are treatment recommendations, not a requirement to wait while severe symptoms or risk remain unaddressed.

Children and young people follow a separate pathway. Within the first month, consider active monitoring or individual trauma-focused CBT for under-eighteens with acute stress disorder or clinically important PTSD symptoms. Beyond one month, consider individual trauma-focused CBT for ages five to six. For ages seven to seventeen, consider it at one to three months and offer it beyond three months. Child trauma-focused CBT usually involves six to twelve sessions, with more when clinically indicated. Consider EMDR for ages seven to seventeen beyond three months only after non-response to or non-engagement with trauma-focused CBT. Adapt treatment to development and involve safe carers appropriately; they may also need separate support.

For subthreshold symptoms in the first month, active monitoring with follow-up within a month is an option. This differs from compulsory psychological debriefing, which NICE advises against for prevention or treatment of PTSD. Care should allow choice and control over disclosure. Comorbid depression is often treated by addressing PTSD first, but severe depression that prevents trauma work or creates significant risk may need priority. Substance misuse should not by itself exclude a person from PTSD treatment; dissociation, emotional dysregulation and unstable circumstances require an individual engagement and safety plan.

    1. 1Allow additional time to establish trust, identify barriers and agree practical measures for staying safe during and between sessions.
    2. 2Coordinate treatment of severe depression, substance-related problems or housing danger as clinically indicated without making an unsupported permanent exclusion from trauma therapy.
    3. 3Prepare for treatment ending, rehearse coping with anniversaries and reminders, and arrange booster sessions or further support when needed.
