Cognitive Behaviour Therapy for Depersonalisation Derealisation Disorder (CBT-f-DDD): Study protocol for a randomised controlled feasibility trial.

Background: Depersonalisation-Derealisation Disorder (DDD) is a distressing mental health condition which causes individuals to have a sense of 'unreality' or detachment about themselves and/or the world around them. DDD is chronically under-researched, and as a result, under-diagnosed, with a population prevalence of about 1%. In systematic reviews, Cognitive Behavioural Therapy (CBT) has been found to be the only intervention with significant clinical impact on alleviating the symptoms of DDD.

A brief CBT intervention for depersonalisation-derealisation disorder in psychosis: Results from a feasibility randomised controlled trial.

Background And Objectives: Depersonalisation/derealisation symptoms are prevalent in psychosis patients, are associated with increased impairment, and may maintain psychosis symptoms. We aimed to establish the feasibility and acceptability of a brief, six session therapy protocol adapted from a Cognitive-Behavioural model of Depersonalisation-Derealisation Disorder (DDD) in participants with psychotic symptoms.

Methods: A single-blind, randomised controlled trial was conducted with a treatment-as-usual control condition.

Cognitive Behaviour Therapy (CBT) for Depersonalization Derealization Disorder (DDD): a self-controlled cross-over study of waiting list vs. active treatment.

Depersonalisation-Derealisation Disorder (DDD) has a prevalence of around 1% but is under-recognised and often does not respond to medical intervention. We report on a clinical audit of 36 participants with a diagnosis of chronic DDD who were sequentially recruited from a specialist DDD National Health Service clinic in London, United Kingdom, and who completed Cognitive Behavioural Therapy specifically adapted for DDD. The sample population had a mean age of 38.

Online structured dance/movement therapy reduces bodily detachment in depersonalization-derealization disorder.

Background: Depersonalization-derealization disorder (DDD) is a dissociative disorder encompassing pronounced disconnections from the self and from external reality. As DDD is inherently tied to a detachment from the body, dance/movement therapy could provide an innovative treatment approach.

Materials And Methods: We developed two online dance tasks to reduce detachment either by training body awareness (BA task) or enhancing the salience of bodily signals through dance exercise (DE task).

Assessing responsiveness to direct verbal suggestions in depersonalization-derealization disorder.

The dissociative disorders and germane conditions are reliably characterized by elevated responsiveness to direct verbal suggestions. However, it remains unclear whether atypical responsiveness to suggestion is similarly present in depersonalization-derealization disorder (DDD). 55 DDD patients and 36 healthy controls completed a standardised behavioural measure of direct verbal suggestibility that includes a correction for compliant responding (BSS-C), and psychometric measures of depersonalization-derealization (CDS), mindfulness (FFMQ), imagery vividness (VVIQ), and anxiety (GAD-7).

The Prevalence of Depersonalization-Derealization Disorder: A Systematic Review.

Depersonalization-Derealization disorder (DDD) is a psychiatric condition characterized by persistent feelings of detachment from one's self and of unreality about the outside world. This review aims to examine the prevalence of DDD amongst different populations. A systematic review protocol was developed before literature searching.

Symptom variability in depersonalization-derealization disorder: A latent profile analysis.

Objective: Depersonalization-derealization disorder (DDD) is characterized by diverse symptomatology overlapping with anxiety and dissociative disorders, but the sources of this variability are poorly understood. This study aims to determine whether symptom heterogeneity is attributable to the presence of latent subgroups.

Method: We applied latent profile analysis to psychometric measures of anxiety, depersonalization-derealization, and dissociation in 303 DDD patients.

Towards a neurocognitive approach to dance movement therapy for mental health: A systematic review.

Dance movement therapy (DMT) has become an increasingly recognized and used treatment, though primarily used to target psychological and physical well-being in individuals with physical, medical or neurological illnesses. To contribute to the relative lack of literature within the field of DMT for clinical mental health disorders, using a narrative synthesis, we review the scope of recent, controlled studies of DMT in samples with different psychiatric disorders including depression, schizophrenia, autism and somatoform disorder.

Effectiveness of small group cognitive behavioural therapy for anxiety and depression in Ebola treatment centre staff in Sierra Leone.

Following the 2014 Ebola outbreak, South London and Maudsley NHS Foundation Trust (SLAM) were commissioned to provide a 'culturally appropriate, effective and sustainable' intervention to address the psychological needs of the Sierra Leonean Ebola Treatment Centre (ETC) staff. The study evaluated the effectiveness of group Cognitive Behavioural Therapy (CBT) developed to treat anxiety, depression and functional impairment amongst a sample of former ETC staff in Sierra Leone. Group comparisons explored whether the effect of the intervention differed dependent on the facilitators that delivered it, as well as whether it differed between former staff of high- and low-risk ETC roles.

Training peers to treat Ebola centre workers with anxiety and depression in Sierra Leone.

Background: Following the 2014 Ebola virus disease (EVD) outbreak in West Africa, the UK Department for International Development funded South London and Maudsley National Health Service (NHS) to develop a psychological intervention that ex-Ebola Treatment Centre (ETC) staff could be trained to deliver to their peers to improve mental health in Sierra Leone.

Aim: The two key aims were to assess the feasibility of training a national team to deliver a cognitive behavioural therapy (CBT)-based group intervention, and to evaluate the effectiveness of the overall intervention within this population.

Methods: UK clinicians travelled to Sierra Leone to train a small team of ex-ETC staff in a three-phased CBT-based intervention.

Integrated Trauma-Focused Cognitive-Behavioural Therapy for Post-traumatic Stress and Psychotic Symptoms: A Case-Series Study Using Imaginal Reprocessing Strategies.

Despite high rates of trauma in individuals with psychotic symptoms, post-traumatic stress symptoms are frequently overlooked in clinical practice. There is also reluctance to treat post-traumatic symptoms in case the therapeutic procedure of reprocessing the trauma exacerbates psychotic symptoms. Recent evidence demonstrates that it is safe to use reprocessing strategies in this population.

Attributions, appraisals and attention for symptoms in depersonalisation disorder.

A cognitive-behavioural model of depersonalisation disorder (DPD) suggests that catastrophic attributions and appraisals, and increased attention to symptoms, play important roles in the development and maintenance of the disorder. Empirical testing of this model was investigated in three groups: 25 patients with DPD, 21 patients with anxiety (obsessive-compulsive or panic disorder), and 22 psychiatrically healthy participants. Task 1 examined attributions for ambiguous symptoms.

Prevalence and childhood antecedents of depersonalization syndrome in a UK birth cohort.

Purpose: Depersonalization syndrome is characterised by a sense of unreality about the self [depersonalization (DP)] and/or the outside world [derealization (DR)]. Prevalence estimates vary widely. Little is known about childhood antecedents of the disorder although emotional abuse is thought to play a role.

Cognitive-behaviour therapy for depersonalisation disorder: an open study.

Depersonalisation (DP) and derealisation (DR) are subjective experiences of unreality in, respectively, one's sense of self and the outside world. These experiences occur on a continuum from transient episodes that are frequently reported in healthy individuals to a chronic psychiatric disorder that causes considerable distress (depersonalisation disorder: DPD). Despite the relatively high rates of reporting these symptoms, little research has been conducted into psychological treatments for this disorder.

Are there two qualitatively distinct forms of dissociation? A review and some clinical implications.

This review aims to clarify the use of the term 'dissociation' in theory, research and clinical practice. Current psychiatric definitions of dissociation are contrasted with recent conceptualizations that have converged on a dichotomy between two qualitatively different phenomena: 'detachment' and 'compartmentalization'. We review some evidence for this distinction within the domains of phenomenology, factor analysis of self-report scales and experimental research.
