Overview

Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can affect those who have experienced or observed a traumatic incident, sequence of events, or combination of circumstances.

In the general population, the lifetime prevalence of PTSD is approximately 3.9% worldwide.

PTSD impacts not only the individual experiencing the condition but also the family and loved ones around them. It might be difficult to live with someone who has PTSD. Even the most devoted family members may suffer from living with someone who is easily frightened, experiences nightmares, or shuns social situations.

Friendships and intimate family ties may be difficult for trauma survivors suffering from PTSD. In turn, these symptoms may affect how a loved one reacts to the trauma survivor. PTSD symptoms can lead to issues with trust, intimacy, communication, and problem-solving.¹

Treatment for PTSD can often eliminate symptoms. Some people may have symptoms less frequently or with less intensity. Following treatment, patients will have acquired new coping mechanisms for their symptoms. The quality of life is often improved for those who receive treatment, such as Cognitive Behavioural Therapy (CBT).²

Understanding PTSD

PTSD most usually arises following an extensive traumatic experience or after a particularly stressful, upsetting or stressful life event.³

Some examples of events/experiences that may lead to the onset of PTSD may include:

• War and military conflict
• Serious and life-threatening health conditions
• Death of loved ones
• Physical and/or sexual abuse 
• Childhood trauma
• Traumatic events in the workplace
• Traumatic events in childbirth 

PTSD is not limited to these causes, however, they are some of the most common risk factors.

PTSD can trigger an array of symptoms, which can be categorised into mental or physical.^4,5

Some common examples of these symptoms are:

• Life-like flashbacks
• Intense and realistic nightmares
• Physical pain manifestations
• Hypervigilance
• Difficulty sleeping/lack of sleep
• Symptoms of anxiety 
• Fight, flight, or freeze response
• Symptoms of avoidance 

A person's capacity to work, carry out daily tasks, and interact with friends and family can all be impacted by PTSD. When a person with PTSD tries not to think or feel to shut out terrible memories, they might frequently come across as aloof or uninterested. This may prevent them from engaging in family activities or turning down offers of assistance. Family members may feel abandoned as a result of this.

Overview of CBT

Of all the psychotherapies, CBT is the most widely used and thoroughly researched. It is a fusion of behavioural therapy and cognitive therapy, two different therapeutic modalities. It's a type of talking therapy where your thoughts and behaviours can be altered to manage your challenges better.^6,7

As CBT is a talking therapy, it can be used flexibly and adapted for different mental health conditions. By breaking down large problems into smaller ones, cognitive behavioural therapy (CBT) seeks to help you cope with them more constructively. It searches for achievable ways to elevate your mood every day. When it comes to PTSD, CBT aims to assist the sufferer in rethinking how they perceive themselves, their capacity for coping, and traumatic events.

Key components of CBT for PTSD

One of the primary components of CBT when treating PTSD is psychoeducation. This particular method helps the patient to understand their PTSD and normalise their reactions. The therapist helps the patient understand trauma and its aftereffects, including the emotional and behavioural reactions that it frequently elicits in people. This also entails assisting them with behaviour control techniques.^8.9

Another key component is exposure therapy. By exposing patients to their traumatic memories in a secure setting, this kind of intervention helps them confront and manage their worries. Exposure can take the form of writing, seeing individuals or locations that bring up memories of the trauma, or mental images.

Exposing the person to the environment containing the feared situation can also be accomplished through virtual reality, which creates a virtual environment that mimics the traumatic experience. The traumas in this method are often introduced gradually with the hope of helping the patient’s reactions to become less sensitive over time, which is also known as systematic desensitisation.

Cognitive processing skills may also be involved as part of the patient's therapy. Trauma can be quite perplexing to people, and they may find it difficult to process the events healthily. Therapists can assist people in identifying and correcting false beliefs about it and comprehending the connection between behaviours, thoughts, and feelings. This encourages the patient to challenge their negative results and change their maladaptive beliefs.

Finally, the patient will be taught to build their coping skills through stress inoculation training (SIT). SIT teaches coping mechanisms to handle the stress that may accompany PTSD to lessen anxiety. SIT is a treatment that can be used alone or in conjunction with other CBT modalities.

Teaching people to respond to their symptoms differently is the major objective. This is accomplished by providing several coping mechanisms, such as muscular relaxation, assertiveness training, breathing retraining, cognitive restructuring, and more.

This therapeutic process is continued for as long as the patient needs and a plan is made, which sets goals and expectations for the patient to work towards while monitoring their progress and making any relevant adjustments.

Effectiveness of CBT

Current research shows that CBT has been certified as a safe and effective intervention for PTSD, but it can also be coupled with some complications:

• Comorbidities or other co-existing medical conditions 
• Patients dropping out of therapy
• Adverse effects, although this is an area that is not highly reported 
• Online therapy may not be as effective as face-to-face CBT

In comparison to other supportive therapies, such as Eye Movement Desensitisation and Movement (EMDR), research shows that CBT is superior and more effective. In a particular review, CBT was shown to have significantly higher remission rates.¹⁰ Some therapies also had similar compliance and efficacy rates as CBT, namely cognitive therapies and exposure therapy (ET).¹⁰

Research also shows that CBT is effective in the long-term for PTSD, although most data only spans 12 months post-treatment, so more data needs to be collected. In terms of relapse, CBT aims to combat this by identifying the patient’s triggers, building their coping skills, and challenging their negative beliefs.

Aside from this, some studies show that non-response to CBT for PTSD can be as high as 50%, and for these patients, a skilled therapist may be needed to explore their comorbidities, emphasising the importance of completing this therapy with a qualified and trained healthcare professional.⁹

Considerations and challenges of CBT

CBT is flexible in ways that it can be tailored to the individual, however, due to the complex nature of PTSD and other mental health conditions, there can be some complications and limitations for the healthcare professional administering the treatment, such as:

Cultural sensitivity

It is imperative for therapists to possess cultural sensitivity and awareness regarding the distinct cultural elements that can impact trauma expression and experience. By attempting to incorporate an understanding of a client's ethnic, linguistic, racial, and cultural heritage into treatment, culturally sensitive practitioners are urged to build skills and practices that are responsive to clients' various worldviews and cultural backgrounds.¹¹

Comorbidity

PTSD and other mental health issues like depression or drug use disorders frequently coexist. A thorough treatment strategy and collaboration with other healthcare providers are necessary to address comorbidities.

Resistance and avoidance

Resistance or avoidance behaviours are common in PTSD sufferers, and they can impede the healing process. It is essential to address these behaviours in a secure therapy setting. This may involve building a rapport with the patient before jumping straight into the CBT so that they feel safe.

Summary

To sum up, CBT is a fundamental component of the all-encompassing treatment of PTSD. It provides a methodical and evidence-based strategy to manage the complex interactions between cognitive distortions, avoidance behaviours, and the emotional distress brought on by trauma. The focus that CBT places on cognitive restructuring, exposure therapy, and developing skills highlights how effective it is at assisting people with PTSD to achieve beneficial results.

However, it's important to recognise some boundaries. During therapy, resistance, avoidance, and the intense emotional memories associated with trauma may present difficulties. To effectively navigate the complex and varied nature of PTSD experiences, therapists need to maintain a high level of competency and practise cultural sensitivity. Comorbidities emphasise even more the necessity of a team-based, comprehensive approach to treatment.
