Complex Post-Traumatic Stress Disorder (Complex PTSD or cPTSD) represents a profound and multifaceted condition categorised within the trauma and stressor-related disorders in the ICD-11. Emerging out of exposure to severe, repetitive, or prolonged traumatic events, such as long-term abuse, violence, or profound neglect, cPTSD encapsulates not only the core symptoms of PTSD, which include re-experiencing traumatic events, avoidance of trauma-related stimuli, and hypervigilance, but also extends to deeper psychological disturbances. There is a good self-help guide at NHS Inform (Scotland).

What distinguishes cPTSD from standard PTSD is its broader impact on the victim’s psychological framework. Individuals suffering from cPTSD experience significant difficulties in emotional regulation, characterised by persistent feelings of sadness, explosive anger, or subdued emotional responsiveness. The disorder also deeply affects the victim’s self-perception and interpersonal relationships, instilling persistent feelings of worthlessness and pervasive difficulties in forming close relationships. Recognised officially in the latest revision of the World Health Organisation’s International Classification of Diseases (ICD-11 CDDR), cPTSD addresses the complex and enduring impact of chronic trauma on an individual’s mental health, paving the way for more tailored and effective therapeutic interventions.
Complex PTSD often exhibits symptom overlap with personality disorders, particularly in emotional instability and interpersonal difficulties. This convergence can complicate diagnoses, as both conditions manifest in deeply ingrained, maladaptive patterns affecting mood regulation and social relationships. Recognising these overlaps is crucial for accurately diagnosing and treating the unique aspects of each disorder.
Diagnostic criteria for cPTSD
The diagnostic criteria for Complex Post-Traumatic Stress Disorder (cPTSD) as outlined in the ICD-11 are specified to capture the complexity of symptoms that extend beyond those typically associated with PTSD. Here are the key criteria numerated:
- Exposure to an event or series of events of an extremely threatening or horrific nature – most commonly prolonged or repetitive events from which escape is difficult or impossible – is required for diagnosis. Such events include, but are not limited to, torture, concentration camps, slavery, genocide campaigns and other forms of organised violence, prolonged domestic violence, and repeated childhood sexual or physical abuse.
- Following the traumatic event, the development of a characteristic syndrome lasting for at least several weeks consists of all three of the following core elements of post-traumaticstress disorder.
- The traumatic event is re-experienced in the present: it is not just remembered but is experienced as occurring again in the here and now. This typically occurs in the form of vivid intrusive memories or images; flashbacks, which can vary from mild (there is a transient sense of the event occurring again in the present) to severe (there is a complete loss of awareness of present surroundings); or repetitive dreams or nightmares that are thematically related to the traumatic event. Re-experiencing is typically accompanied by strong or overwhelming emotions, such as fear or horror, and strong physical sensations. Re-experiencing in the present can also involve feelings of being overwhelmed or immersed in the same intense emotions that were experienced during the traumatic event, without a prominent cognitive aspect, and may occur in response to reminders of the event. Reflecting on or ruminating about the event and remembering the feelings experienced at that time are not sufficient to meet the re-experiencing requirement.
- Reminders likely to produce re-experiencing of the traumatic event are deliberately avoided. Deliberate avoidance may take the form either of active internal avoidance of thoughts and memories related to the event, or external avoidance of people, conversations, activities or situations reminiscent of the event. In extreme cases, the person may change their environment (e.g. move house or change jobs) to avoid reminders.
- There are persistent perceptions of heightened current threat – for example, as indicated by hypervigilance or an enhanced startle reaction to stimuli such as unexpected noises. Hypervigilant people constantly guard themselves against danger, and feel themselves or others close to them to be under immediate threat either in specific situations or more generally. They may adopt new behaviours designed to ensure safety (e.g. not sitting with their back to the door, repeatedly checking in vehicles’ rear-view mirrors). In complex post-traumatic stress disorder, unlike in post-traumatic stress disorder, the startle reaction may in some cases be diminished rather than enhanced.
- The presentation is characterised by severe and pervasive problems in affect regulation. Examples include heightened emotional reactivity to minor stressors, violent outbursts, reckless or self-destructive behaviour, dissociative symptoms when under stress, and emotional numbing – particularly the inability to experience pleasure or positive emotions.
- Persistent beliefs about oneself as diminished, defeated or worthless are accompanied by deep and pervasive feelings of shame, guilt or failure related to the stressor. For example, the individual may feel guilty about not having escaped from or succumbing to the adverse circumstance, or not having been able to prevent the suffering of others.
- Persistent difficulties in sustaining relationships and in feeling close to others are present. The individual may consistently avoid, deride or have little interest in relationshipsand social engagement more generally. Alternatively, there may be occasional intense relationships, but the individual has difficulty sustaining them.
- The disturbance results in significant impairment in personal, family, social, educational, occupational or other important areas of functioning. If functioning is maintained, it is only through significant additional effort.
Additional symptoms specific to cPTSD:
- Problems in affect regulation: The individual may experience persistent difficulties in controlling emotions, which might manifest as explosive anger, persistent sadness, or inhibited emotional responsiveness.
- Beliefs about oneself as diminished, defeated, or worthless: This can involve feelings of profound and persistent shame or guilt, and the belief that one is deeply flawed or different from other people.
- Difficulties in sustaining relationships and feeling close to others: These include problems in feeling close to others, sustaining relationships, or feeling socially isolated, marked by a persistent lack of trust or a tendency to avoid close relationships.
The ICD-11 emphasises that the diagnosis of cPTSD should be distinct from, yet related to, PTSD by the complexity and severity of its symptomatology, which extends significantly beyond the typical symptom clusters of re-experiencing, avoidance, and hyperarousal, reflecting the pervasive and enduring impact of chronic trauma.
| Aspect | PTSD | cPTSD |
|---|---|---|
| Traumatic Event | Exposure to a traumatic event, typically involving actual or threatened death or serious injury. | Exposure to an event or series of events of an extremely threatening or horrific nature, most commonly prolonged or repetitive. |
| Re-experiencing | Recurrent, involuntary, and intrusive memories, flashbacks, or nightmares of the event. | Similar to PTSD, includes re-experiencing the traumatic event(s) in the present through flashbacks, nightmares, and distress. |
| Avoidance | Avoidance of thoughts, feelings, or reminders associated with the traumatic event. | Also features avoidance but often more pervasive, including profound minimisation of exposure to any reminders of the trauma. |
| Hyperarousal | Marked alterations in arousal and reactivity associated with the trauma, including hypervigilance and exaggerated startle response. | Persistent perceptions of heightened current threat, similar to PTSD but often more pronounced in hypervigilance and alertness. |
| Affective Regulation | Not directly addressed under PTSD criteria. | Persistent difficulties in regulating emotions, manifested as explosive anger, persistent sadness, or inhibited emotional responsiveness. |
| Self-Perception | Typically not addressed as a criterion. | Includes persistent beliefs about oneself as diminished, defeated, or worthless, often accompanied by deep and persistent shame or guilt. |
| Interpersonal Relationships | Issues might be present but not a core focus of diagnosis. | Pronounced difficulties in sustaining relationships, feeling close to others, and a persistent lack of trust or avoidance of closeness. |
| Duration of Symptoms | Symptoms need to persist for at least one month. | Symptoms are generally enduring and compounded over time, reflecting the chronic nature of the underlying trauma. |
This table highlights the distinctions between PTSD and cPTSD, illustrating that while both disorders arise from exposure to trauma, cPTSD includes additional layers of emotional and interpersonal dysfunction that reflect the enduring and complex nature of the trauma experienced.
cPTSD and Personality Disorder
The overlap between Complex Post-Traumatic Stress Disorder (cPTSD) and personality disorders, particularly Emotionally Unstable Personality Disorder (EUPD), commonly known as Borderline Personality Disorder (BPD), manifests in shared symptomatology and similar behavioural patterns. This overlap can complicate clinical assessments and requires careful differential diagnosis to ensure appropriate treatment approaches.
| Feature | Complex PTSD (cPTSD) | Personality Disorders (PD) |
|---|---|---|
| Emotional Regulation | Persistent difficulties in regulating emotions, manifested as explosive anger, persistent sadness, or subdued emotional responsiveness. | Emotional instability is common, especially in EUPD/BPD, with frequent intense emotional changes and mood swings. |
| Interpersonal Relationships | Difficulties in forming close relationships due to mistrust and alienation, often resulting from past trauma. | Patterns of unstable and intense relationships, often due to fears of abandonment and identity issues. |
| Self-Perception | Feelings of worthlessness and profound shame, driven by the traumatic experiences. | Chronic feelings of emptiness and distorted self-image, often independent of specific traumatic events. |
| Impulse Control | May exhibit self-destructive behaviour or substance misuse as coping mechanisms for emotional pain. | Impulsive behaviour is characteristic, including self-harm and risky behaviours, often as a response to stress. |
| Sense of Threat | Heightened state of vigilance and exaggerated startle response due to a persistent sense of threat from the trauma history. | Although not specific, a generalised feeling of insecurity or threat can be part of the disorder’s symptomatology. |
This table clarifies that while cPTSD and PD share significant symptom overlap, particularly in emotional and interpersonal domains, the underlying causes and specific manifestations can differ. Understanding these nuances is crucial for clinicians to differentiate between the two and tailor treatment strategies effectively.
| Feature | Complex PTSD (cPTSD) | Personality Disorders (PD) |
|---|---|---|
| Aetiology | Primarily results from prolonged exposure to severe, repetitive trauma such as abuse, neglect, or captivity. | Develops from a complex interplay of genetic, environmental, and psychological factors, not solely trauma-based though trauma may be contributory |
| Core Symptoms | Symptoms extend beyond typical PTSD to include affective dysregulation, negative self-concept, and interpersonal issues. | Focuses on enduring patterns of behaviour and inner experience that deviate markedly from cultural expectations. |
| Trauma Specificity | Directly linked to traumatic events and the individual’s response to such events. | While trauma can play a role, PDs are not specifically trauma-related and include a broader range of origins. |
| Symptom Onset | Symptoms usually begin after a trauma but can become noticeable long after exposure to the traumatic events. | Symptoms typically manifest during adolescence or early adulthood and are pervasive over time. |
| Treatment Focus | Treatment is trauma-focused, aiming to address the memories of the trauma and its pervasive impact on the individual’s life. | Treatment often includes long-term psychotherapy focused on behavioural and emotional regulation, and interpersonal skills. |
| Diagnostic Criteria | Includes criteria specific to the re-experiencing of trauma, avoidance, and a heightened state of alertness, along with additional complex symptoms. | Diagnosis is based on a wider range of behavioural and emotional criteria, not necessarily tied to trauma responses. |
| Therapeutic Outcomes | Therapeutic interventions aim to alleviate trauma-related symptoms and improve emotional and social functioning. | Focus is on long-term management of symptoms, improving interpersonal relationships, and self-management skills. |
This table highlights the distinct nature of each condition, underscoring the importance of differentiated diagnosis and treatment plans that are sensitive to the unique features and origins of cPTSD and PD.
When comparing treatment approaches for Complex PTSD (cPTSD) and Emotionally Unstable Personality Disorder (EUPD, also known as Borderline Personality Disorder or BPD), it is important to highlight both the similarities in therapeutic techniques used and the unique strategies tailored to each disorder.
| Treatment Aspect | Complex PTSD (cPTSD) | Emotionally Unstable Personality Disorder (EUPD/BPD) |
|---|---|---|
| Therapeutic Goals | Focus on processing and integrating traumatic memories, rebuilding a sense of safety, and enhancing emotional regulation. | Aim to stabilise emotional swings, improve interpersonal relationships, and reduce self-harmful behaviours. |
| Therapy Types | Trauma-focused therapies such as EMDR (Eye Movement Desensitisation and Reprocessing), Trauma-focused CBT, and narrative therapy. | Dialectical Behaviour Therapy (DBT), Schema Therapy, and Transference-Focused Psychotherapy are commonly used. |
| Focus on Relationships | Emphasis on rebuilding trust in relationships and improving interpersonal effectiveness within a safe therapeutic environment. | Intensive focus on interpersonal relationships; therapy often includes learning skills for managing and sustaining relationships. |
| Emotional Regulation | Key component involves learning to manage intense emotional responses stemming from triggers related to past trauma. | Central focus on emotional regulation skills to manage rapid and intense emotional shifts and prevent crisis behaviours. |
| Duration of Treatment | May vary based on the severity of trauma and the individual’s response to therapy; often long-term. | Typically long-term, with structured treatment aiming to gradually achieve stability and improve functioning. |
| Techniques Employed | May incorporate somatic experiencing, mindfulness practices, and grounding techniques to manage symptoms. | Often uses skills training groups, mindfulness, and crisis management techniques as part of DBT or other modalities. |
| Treatment Challenges | Challenges include managing dissociation, overcoming avoidance of trauma reminders, and integrating traumatic experiences. | Challenges include addressing frequent crises, reducing suicidal and self-harm risks, and managing intense emotional episodes. |
| Outcome Expectations | Focus on reducing the impact of trauma on daily functioning and improving quality of life. | Focus on reducing problematic behaviours, improving emotional control, and enhancing social functioning. |
This table illustrates that while both cPTSD and EUPD involve comprehensive and often long-term treatment strategies, the specific focus, therapeutic goals, and techniques can differ significantly due to the distinct nature of each disorder. Understanding these differences is crucial for tailoring treatment approaches to meet the unique needs of individuals with either condition.
Treatment or management of cPTSD
Choosing the right therapeutic approach for treating Complex PTSD (cPTSD) involves considering various clinical features and individual characteristics that affect the condition. Clinicians should consider the following key clinical features when selecting and tailoring treatment strategies for cPTSD:
- Severity and Nature of Trauma: The type (e.g., physical, sexual abuse, long-term captivity) and severity of trauma, as well as the duration (chronic versus single-episode trauma), greatly influence the treatment approach. Chronic and severe exposure typically necessitates more intensive, prolonged treatment modalities.
- Symptom Presentation: The range and severity of symptoms, such as the degree of emotional dysregulation, dissociation, or the presence of severe depression and anxiety, guide the choice of specific therapeutic interventions. For instance, higher levels of dissociation might require initial stabilizing interventions before engaging in trauma-focused therapies.
- Functional Impairment: The level of impairment in daily functioning, including interpersonal relationships and occupational performance, can determine the intensity and support level required in therapy. More significant impairment might necessitate a multi-disciplinary approach involving social support systems, occupational therapy, and more.
- Comorbidities: The presence of other psychiatric conditions such as depression, anxiety disorders, or substance use disorders can complicate the treatment of cPTSD. Treatment plans need to address these comorbid conditions simultaneously or sequentially, depending on their impact on the individual’s functioning and well-being.
- Coping Styles and Resilience: Individual differences in coping mechanisms, resilience, and existing support systems play a crucial role in shaping the treatment approach. Adaptive coping skills might allow for more rigorous therapeutic techniques, whereas maladaptive coping might require initial work on developing healthier coping strategies.
- Patient Preferences and Treatment History: Individual preferences for certain types of therapy (e.g., more or less directive, willingness to engage in exposure-based treatments) and previous treatment experiences (what has been effective or not) are critical in planning effective interventions.
- Age and Developmental Stage: The age and developmental context of the patient can influence treatment choice. Therapies for children and adolescents with cPTSD are often different in terms of engagement, methods, and the involvement of family compared to adults.
- Cultural and Socioeconomic Factors: Cultural background can affect how trauma and recovery are perceived; thus, treatments need to be culturally sensitive. Socioeconomic factors also influence access to care and availability of resources, which may dictate the feasibility of certain treatment options.
In clinical practice, a thorough assessment using structured clinical interviews and standardised assessment tools is essential for understanding these features and effectively planning the treatment. The choice of therapy is often a combination of evidence-based practices tailored to meet the unique needs and circumstances of the individual, ensuring a holistic and patient-centred approach to recovery from cPTSD. As many will realise, the job of diagnosing and deciding which treatment is right depends on a lot of factors. Candidate patients and their loved ones can benefit from thinking about all this. They should always feel free to ask questions.
Summary and take away points
- Definition and Distinction: Complex PTSD is recognised in the ICD-11 and is characterised by symptoms that extend beyond traditional PTSD, involving significant emotional regulation issues, disturbances in self-perception, and difficulties in maintaining personal relationships.
- Overlap with Personality Disorders: cPTSD shares several clinical features with personality disorders, especially Emotionally Unstable Personality Disorder (EUPD), such as emotional instability and challenges in interpersonal relationships.
- Diagnostic Criteria: For cPTSD, the ICD-11 outlines specific criteria that include traditional symptoms of PTSD along with additional aspects like affective dysregulation and negative self-concept.
- Treatment Approaches: Treatment for cPTSD typically involves trauma-focused therapies, which may include EMDR and trauma-focused CBT, while personality disorders may require long-term psychotherapy such as DBT or Schema Therapy.
- Choosing Treatment Strategies: Effective treatment depends on various factors including the severity of trauma, symptom presentation, functional impairment, comorbidities, and patient preferences.
- Clinical Implications: Clinicians need to carefully differentiate between cPTSD and personality disorders due to their symptom overlap, ensuring that treatment is accurately targeted to address the specific underlying issues.
