Trauma-Focused Psychological Therapies for PTSD and Complex PTSD: Understanding CBT, EMDR and Specialist Care



BY: Bloomfield Health / July 6, 2026


Trauma-Focused Psychological Therapies for PTSD and Complex PTSD

Experiencing trauma can change the way we think, feel and relate to the world. While many people gradually recover after difficult experiences, others develop post-traumatic stress disorder (PTSD) or complex post-traumatic stress disorder (CPTSD), conditions that can significantly affect relationships, work, sleep and emotional wellbeing.

The good news is that PTSD and CPTSD are highly treatable. Research consistently shows that trauma-focused psychological therapies are among the most effective treatments available, helping many people achieve meaningful and lasting recovery.

At Bloomfield Health, we are delighted to welcome Dr Perera-Delcourt, Principal Clinical Psychologist, whose extensive experience in trauma-focused therapies further strengthens our specialist trauma service.

What are PTSD and Complex PTSD?

PTSD can develop following exposure to a traumatic event such as:

  • Serious accidents
  • Physical or sexual assault
  • Military combat
  • Medical trauma
  • Natural disasters
  • Witnessing traumatic events

Symptoms commonly include:

  • Intrusive memories or flashbacks
  • Nightmares
  • Avoidance of reminders
  • Hypervigilance
  • Feeling constantly on edge
  • Difficulties with concentration and sleep

Complex PTSD (CPTSD), recognised in the International Classification of Diseases (ICD-11), usually develops after prolonged or repeated interpersonal trauma, such as childhood abuse, domestic abuse, trafficking, torture or captivity.

In addition to the core symptoms of PTSD, people with CPTSD often experience:

  • Persistent difficulties regulating emotions
  • Deep feelings of shame or worthlessness
  • Difficulties trusting others or maintaining relationships
  • A negative sense of self
  • Problems feeling safe, even when objectively safe

Many individuals with CPTSD have also developed understandable coping strategies that helped them survive earlier adversity but may no longer be helpful in the present.

Why Trauma-Focused Therapy Matters

Not all therapy is specifically designed to treat trauma.

While supportive therapy can provide valuable emotional support, evidence consistently shows that trauma-focused psychological therapies are most effective at treating PTSD because they directly help the brain process traumatic memories rather than simply talking about them.

The National Institute for Health and Care Excellence (NICE) recommends trauma-focused psychological therapies as the first-line treatment for PTSD whenever appropriate.

Two of the most well-established approaches are:

  • Trauma-Focused Cognitive Behavioural Therapy (TF-CBT)
  • Eye Movement Desensitisation and Reprocessing (EMDR)

Trauma-Focused Cognitive Behavioural Therapy (TF-CBT)

Trauma-Focused CBT is a structured, evidence-based treatment that helps people understand how traumatic experiences continue to influence thoughts, emotions, physical sensations and behaviour.

Rather than asking someone to “forget” what happened, TF-CBT aims to help the brain recognise that the trauma belongs in the past rather than feeling as though it is happening in the present.

Treatment is carefully paced and may include:

  • Developing a shared understanding (formulation) of how trauma affects the individual
  • Learning skills to manage anxiety and emotional distress
  • Identifying and gently challenging unhelpful beliefs such as guilt, shame or self-blame
  • Processing traumatic memories in a safe and structured way
  • Reducing avoidance of reminders that keep PTSD going
  • Rebuilding confidence, relationships and everyday functioning

For people with complex trauma, therapy often also includes work on emotional regulation, interpersonal difficulties and rebuilding a stable sense of self.

What is EMDR?

Eye Movement Desensitisation and Reprocessing (EMDR) is another highly effective, evidence-based treatment for PTSD.

During EMDR, the therapist helps the individual recall aspects of a traumatic memory while simultaneously engaging in bilateral stimulation, most commonly guided eye movements, although tapping or auditory tones may also be used.

Researchers believe this process helps the brain reprocess memories that have become “stuck” following trauma, allowing them to be stored more adaptively.

People often report that after successful EMDR:

  • Memories become less vivid and emotionally overwhelming
  • Flashbacks reduce
  • Feelings of fear, shame or helplessness lessen
  • They are able to think about the event without feeling as though they are reliving it

Although the exact neurobiological mechanisms continue to be investigated, EMDR has one of the strongest evidence bases for treating PTSD and is recommended by NICE and many international clinical guidelines.

Treating Complex PTSD Requires More Than One Technique

Complex PTSD often requires a broader, individualised approach.

Many people benefit from a phase-based model of treatment, which may include:

Phase 1: Stabilisation

Developing emotional regulation skills, improving safety, strengthening relationships and building resilience before trauma processing begins.

Phase 2: Trauma Processing

Using therapies such as trauma-focused CBT or EMDR to process traumatic memories.

Phase 3: Reintegration

Supporting people to reconnect with valued activities, relationships, identity and future goals.

Treatment is always tailored to the individual. Some people move quickly through these phases, while others benefit from spending longer developing stability before processing traumatic memories.

Experience at the Centre for Anxiety Disorders and Trauma (CADAT)

Before joining Bloomfield Health, Dr Perera-Delcourt worked at the Centre for Anxiety Disorders and Trauma (CADAT) at the South London and Maudsley NHS Foundation Trust.

CADAT is one of the UK’s leading specialist psychological treatment centres for anxiety disorders and trauma-related conditions. Based within the internationally recognised Maudsley Hospital, the service provides highly specialised assessment and treatment for individuals with complex presentations that often require advanced psychological expertise.

The service has played an important role in developing and evaluating evidence-based treatments for PTSD, obsessive-compulsive disorder, health anxiety, panic disorder and other anxiety disorders. It is closely linked with King’s College London and has contributed significantly to international research into cognitive behavioural therapies.

Experience within a nationally recognised specialist service means clinicians gain extensive expertise in delivering complex, evidence-based psychological interventions to individuals with severe or longstanding difficulties.

An Integrated Approach to Trauma Care

At Bloomfield Health, we recognise that recovery from trauma is rarely one-size-fits-all.

Our multidisciplinary team includes consultant psychiatrists, clinical psychologists and psychotherapists who work together when appropriate to provide comprehensive assessment and treatment.

Where clinically indicated, treatment may include:

  • Psychological assessment and formulation
  • Trauma-focused CBT
  • EMDR
  • Compassion-Focused Therapy
  • Psychiatric assessment where diagnosis is uncertain or symptoms overlap with other conditions
  • Medication where appropriate
  • Collaborative care for complex trauma presentations

Our aim is always to provide evidence-based care that is compassionate, collaborative and tailored to the individual.

Taking the First Step

Many people delay seeking help because they worry that talking about trauma will make things worse.

A skilled trauma therapist works carefully and collaboratively, ensuring treatment proceeds at a pace that feels manageable and safe. Therapy is never about forcing someone to revisit experiences before they are ready.

With the right support, recovery is possible. Many people find they not only experience fewer symptoms but also regain confidence, reconnect with relationships and develop a renewed sense of purpose.

If you would like to learn more about trauma-focused therapy or arrange an assessment, our team would be pleased to discuss how we may be able to help.
