Explicit and implicit sense of agency in depersonalisation experiences.

The sense of agency, the feeling of controlling one's bodily actions and the world is altered in Depersonalisation (DP), a condition that makes people feel detached from one's self and body. To investigate the link between depersonalisation and both implicit and explicit sense of agency, an online study was conducted using the influential Intentional Binding paradigm in a sample of non-clinical DP participants. The results did not reveal significant differences between individuals with low and high occurrences of DP experiences on the implicit and explicit sense of agency. However, participants with high occurrences of DP experiences showed a more time-sensitive explicit sense of agency and greater temporal distortions for short intervals in the absence of self-initiated motion. These results suggest that there is a discrepancy between implicit and explicit sense of agency in people with high levels of depersonalisation. Altogether, these findings call for further investigations of the key role of time perception on altered sense of self and agency in both non-clinical and clinical populations, to disentangle the mechanisms associated with the explicit and implicit sense of agency.

Behavioural, autonomic, and neural responsivity in depersonalisation-derealisation disorder: A systematic review of experimental evidence.

Depersonalisation-derealisation disorder (DDD) is characterised by distressing experiences of separation from oneself and/or one's surroundings, potentially resulting from alterations in affective, cognitive, and physiological functions. This systematic review aimed to synthesise current experimental evidence of relevance to proposed mechanisms underlying DDD, to appraise existing theoretical models, and to inform future research and theoretical developments. Studies were included if they tested explicit hypotheses in DDD samples, with experimental manipulations of at least one independent variable, alongside behavioural, subjective, neurological, affective and/or physiological dependent variables. Some evidence for diminished subjective responsivity to aversive images and sounds, and hyperactivation in neurocircuits associated with emotional regulation when viewing aversive images emerged, corroborating neurobiological models of DDD. Inconsistencies were present regarding behavioural and autonomic responsivity to facial expressions, emotional memory, and self-referential processing. Common confounds included small sample sizes, medication, and comorbidities. Alterations in affective reactivity and regulation appear to be present in DDD; however, further research employing more rigorous research designs is required to provide stronger evidence for these possible mechanisms.

Finding neural correlates of depersonalisation/derealisation disorder via explainable CNN-based analysis guided by clinical assessment scores.

Mental health disorders are typically diagnosed based on subjective reports (e.g., through questionnaires) followed by clinical interviews to evaluate the self-reported symptoms. Therefore, considering the interconnected nature of psychiatric disorders, their accurate diagnosis is a real challenge without indicators of underlying physiological dysfunction. Depersonalisation/derealisation disorder (DPD) is an example of dissociative disorder affecting 1-2 % of the population. DPD is characterised mainly by persistent disembodiment, detachment from surroundings, and feelings of emotional numbness, which can significantly impact patients' quality of life. The underlying neural correlates of DPD have been investigated for years to understand and help with a more accurate and in-time diagnosis of the disorder. However, in terms of EEG studies, which hold great importance due to their convenient and inexpensive nature, the literature has often been based on hypotheses proposed by experts in the field, which require prior knowledge of the disorder. In addition, participants' labelling in research experiments is often derived from the outcome of the Cambridge Depersonalisation Scale (CDS), a subjective assessment to quantify the level of depersonalisation/derealisation, the threshold and reliability of which might be challenged. As a result, we aimed to propose a novel end-to-end EEG processing pipeline based on deep neural networks for DPD biomarker discovery, which requires no prior handcrafted labelled data. Alternatively, it can assimilate knowledge from clinical outcomes like CDS as well as data-driven patterns that differentiate individual brain responses. In addition, the structure of the proposed model targets the uncertainty in CDS scores by using them as prior information only to guide the unsupervised learning task in a multi-task learning scenario. A comprehensive evaluation has been done to confirm the significance of the proposed deep structure, including new ways of network visualisation to investigate spectral, spatial, and temporal information derived in the learning process. We argued that the proposed EEG analytics could also be applied to investigate other psychological and mental disorders currently indicated on the basis of clinical assessment scores.

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. Feasibility and acceptability estimates included rates of referral, acceptance, eligibility, consent, satisfaction and improved skills/knowledge to manage depersonalisation. RESULTS: Twenty-one individuals were recruited to the trial. Results suggest that the intervention was feasible and acceptable to participants and there is some signal of effect on clinical outcomes. LIMITATIONS: There were some challenges in recruitment. Recruitment feasibility estimates from the research register used may not be informative for future trials recruiting directly from teams. CONCLUSIONS: Overall, the results suggest that further investigations would be of interest and recommendations for this are made.

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 38.7 years (s.d. = 13.4), 61% were male and 69% were of White ethnicity. Three outcomes were assessed (Cambridge Depersonalisation Scale [CDS], Beck Depression Inventory [BDI], and the Beck Anxiety Inventory [BAI]) at three time points in a naturalistic, self-controlled, cross-over design. Hierarchical longitudinal analyses for outcome response clustered by patient were performed using scores from baseline, beginning, and end of therapy. All scores showed improvement during the treatment period, with medium effect sizes. CBT may be an effective treatment for DDD. However, treatment was not randomly assigned, and the sample was small. More research is needed, including the use of randomisation to assess the efficacy of CBT for DDD.

"My mind goes dead I cannot speak": an expression of DPD.

INTRODUCTION: Here we present a case of Depersonalisation-Derealisation Disorder which involves an unusual environmental trigger and profile of symptoms in a patient with an underlying left frontal encephalomalacia. METHODS: The clinical information has been collected from multiple neurological, psychiatric, neuropsychological examinations and from the patient's medical records. RESULTS: The neuropsychiatric assessment showed depersonalisation, derealisation, de-somatisation and de-affectualisation, along with a good response to SSRI + Lamotrigine; all typical features of DPD. The neuropsychological assessment showed language problems, and other mild cognitive difficulties that may provide a neuropsychological foundation contributing to the DPD episodes. DISCUSSION AND CONCLUSION: Given Mr R's underlying neuropsychological deficit, hearing voices without speech-associated gestures might place excessive demands on his ability to process the information, exacerbating his feelings of threat. This sets up the pattern of suppressed insula activation, and possibly the suppression of the auditory cortex leading to the presented unusual DPD symptoms.

Developing an understanding of the relationship between anxiety and dissociation in adolescence.

Anxiety is a common problem in adolescence which is hypothesised to be associated with dissociation, a range of distressing symptoms linked to reduced psychosocial functioning. Yet, to date, research into the mechanisms of dissociation in adolescents has been limited. The present study investigated the link between trait anxiety and dissociative experiences (depersonalisation and 'felt sense of anomaly') using an online survey. Cognitive appraisals of dissociation, perseverative thinking, and body vigilance were assessed as potential mediating factors of this relationship. 1211 adolescents aged 13-18 years were recruited via social media advertisements and local schools. Linear regression showed a moderate positive relationship between trait anxiety and both dissociation constructs. Hierarchical regression indicated that cognitive appraisals of dissociation and perseverative thinking mediated the relationship between trait anxiety and both dissociation constructs, but trait anxiety was a significant predictor for felt sense of anomaly but not depersonalisation after including the mediators. The final models accounted for 58.7% of variance in depersonalisation and 68.4% of variance in felt sense of anomaly. These results support the hypothesis that dissociation is associated with anxiety in adolescence. They also demonstrate that cognitive-behavioural conceptualisations may be valid for understanding dissociation in adolescence.

Determinants of burnout among nurses and midwives at a tertiary hospital in Ghana: A cross-sectional study.

AIM: This study determined the prevalence and key determinants of burnout among nurses and midwives in Kumasi, Ghana. DESIGN: Hospital-based cross-sectional study. METHOD: A questionnaire was used to obtain data from 391 nurses and midwives at a tertiary hospital in Kumasi, Ghana using simple random sampling. RESULTS: About 84.4% of the participants were females. The majority of the study participants experienced low burnout for all dimensions (58% in emotional exhaustion, 55.5% poor personal accomplishment and 38.3% depersonalization). Multiple regression analysis revealed that high emotional exhaustion was independently predicted by post-graduate education (ß = 6.42, p = .003), lack of support from management (ß = 2.07, p = .024), dislike for leadership style, (ß = 3.54, p < .001) and inadequate number of staff (ß = 2.93, p = .005). Age (ß = 0.35, p = .004), lack of support from management (ß = 1.60, p = .012), and inadequate number of staff (ß = 1.49, p = .034) independently predicted high depersonalisation. Female sex (ß = 4.36, p < .001) and years of practice (ß = -0.26, p < .001) independently predicted low personal accomplishment.

Occupational burnout among teachers: is it seasonal?

The aim of this cross-sectional study was to compare occupational burnout in two groups of teachers from the district of Bijeljina (Bosnia and Herzegovina) measured with the Serbian version of the Maslach Burnout Inventory survey for workers in human services (MBI-HSS) at the beginning (group 1) and the end of the school year 2018/2019 (group 2) to see if there are seasonal differences. The questionnaire also included standard sociodemographic data and job description (primary and/or secondary school position, length of service, and overtime work). The prevalence of emotional exhaustion and depersonalisation was low in both groups. However, emotional exhaustion and depersonalisation scores significantly shifted to higher values between the beginning and the end of the school year. We also found a statistically significant association between emotional exhaustion and overtime and between depersonalisation and work in a secondary school (p<0.05). These findings invite further research of occupational burnout seasonality in schoolteachers, preferably by following up cohorts which would be controlled for sociodemographic and work-related variables.

Cotard delusion, emotional experience and depersonalisation.

INTRODUCTION: Cotard delusion-the delusional belief "I am dead"-is named after the French psychiatrist who first described it: Jules Cotard. Ramachandran and Blakeslee proposed that the idea "I am dead" comes to mind when a neuropathological condition has resulted in complete abolition of emotional responsivity to the world. The idea would arise as a putative explanation: if "I am dead" were true, there would be no emotional responsivity to the world. METHODS: We scrutinised the literature on people who expressed the delusional belief "I am dead", looking for data on whether such patients are reported as entirely lacking in emotional responsivity. RESULTS: In numerous cases, patients with Cotard delusion are described as experiencing emotions including anxiety, fear, guilt, distress, euphoria and worry. CONCLUSIONS: We conclude that complete absence of emotional responsivity cannot be what prompts the delusional idea that one is dead. We propose that, in at least some cases, the idea "I am dead" comes to mind in response to symptoms of depersonalisation or derealisation, often present in cases of Cotard delusion, and give examples of Cotard patients with abnormalities in various neural areas that could be responsible for the presence of such symptoms.

I overthink-Therefore I am not: An active inference account of altered sense of self and agency in depersonalisation disorder.

This paper considers the phenomenology of depersonalisation disorder, in relation to predictive processing and its associated pathophysiology. To do this, we first establish a few mechanistic tenets of predictive processing that are necessary to talk about phenomenal transparency, mental action, and self as subject. We briefly review the important role of 'predicting precision' and how this affords mental action and the loss of phenomenal transparency. We then turn to sensory attenuation and the phenomenal consequences of (pathophysiological) failures to attenuate or modulate sensory precision. We then consider this failure in the context of depersonalisation disorder. The key idea here is that depersonalisation disorder reflects the remarkable capacity to explain perceptual engagement with the world via the hypothesis that "I am an embodied perceiver, but I am not in control of my perception". We suggest that individuals with depersonalisation may believe that 'another agent' is controlling their thoughts, perceptions or actions, while maintaining full insight that the 'other agent' is 'me' (the self). Finally, we rehearse the predictions of this formal analysis, with a special focus on the psychophysical and physiological abnormalities that may underwrite the phenomenology of depersonalisation.

Rationing of Nursing Care and Professional Burnout Among Nurses Working in Cardiovascular Settings.

Introduction: Nursing needs close interpersonal contact with the patient and emotional involvement, therefore can contribute to professional burnout and rationing of nursing care. Aim: Assessing the relationship between the rationing of nursing care and professional burnout in nursing staff. Materials and Methods: The study included a group of 219 nurses working in cardiovascular facilities. This was a cross-sectional study designed to investigate the relationship between factors of the care rationing and professional burnout. The survey data was collected with standardised and research instruments such as the revised Basel Extent of Rationing of Nursing Care questionnaire (BERNCA-R) and the Maslach Burnout Inventory (MBI). Results: The total mean BERNCA-R score was 1.38 (SD = 0.62), while the total MBI score amounted to 38.14 (SD = 22.93). The specific components of professional burnout yielded the values: emotional exhaustion (M = 44.8), job dissatisfaction (M = 40.66), and depersonalisation (M = 28.95). Multiple linear regression showed that independent predictors of BERNCA-R score were emotional exhaustion, depersonalisation, job dissatisfaction, and multi-jobs activity (p < 0.001). Conclusion: The level of rationing of nursing care in cardiovascular facilities increases along with emotional exhaustion, depersonalisation and job dissatisfaction, and multi-jobs activity.

The Psychiatric Symptomology of Visual Snow Syndrome.

Objective: To characterise the psychiatric symptoms of visual snow syndrome (VSS), and determine their relationship to quality of life and severity of visual symptoms. Methods: One hundred twenty-five patients with VSS completed a battery of questionnaires assessing depression/anxiety, dissociative experiences (depersonalisation), sleep quality, fatigue, and quality of life, as well as a structured clinical interview about their visual and sensory symptoms. Results: VSS patients showed high rates of anxiety and depression, depersonalisation, fatigue, and poor sleep, which significantly impacted quality of life. Further, psychiatric symptoms, particularly depersonalisation, were related to increased severity of visual symptoms. The severity/frequency of psychiatric symptoms did not differ significantly due to the presence of migraine, patient sex, or timing of VSS onset (lifelong vs. later onset). Conclusion: Psychiatric symptoms are highly prevalent in patients with VSS and are associated with increased visual symptom severity and reduced quality of life. Importantly, patients with lifelong VSS reported lower levels of distress and milder self-ratings of visual symptoms compared to patients with a later onset, while being equally likely to experience psychiatric symptoms. This suggests that the psychiatric symptoms of VSS are not solely due to distress caused by visual symptoms. While no consistently effective treatments are available for the visual symptomology of VSS, psychiatric symptoms offer an avenue of treatment that is likely to significantly improve patient quality of life and ability to cope with visual symptoms.

Burnout in Professional Psychotherapists: Relationships with Self-Compassion, Work-Life Balance, and Telepressure.

Though negative impacts of COVID-19 on occupational mental health have been reported, the mental health of psychotherapists has not been evaluated in depth. As this occupational group treats ever-increasing mental health problems, it is essential to appraise key factors for their mental health. Accordingly, this study aimed to explore burnout of professional psychotherapists. A total of 110 participants completed self-report measures regarding burnout, self-compassion, work-life balance and telepressure. Correlation, regression and moderation analyses were conducted. Both of the burnout components-emotional exhaustion and depersonalisation-were positively associated with weekly working hours and telepressure, and negatively associated with age, self-compassion and work-life balance. Weekly working hours and work-life balance were significant predictors of emotional exhaustion and depersonalisation. Lastly, self-compassion partially mediated the relationship between work-life balance and emotional exhaustion but did not mediate the relationship between work-life balance and depersonalisation. The findings suggest that maintaining high work-life balance is particularly important for the mental health of psychotherapists, protecting them from burnout. Moreover, self-compassion needs to be cultivated to mitigate emotional exhaustion. Mental health care for this occupational group needs to be implemented to achieve sustainable mental health care for workers and the public.

Theorising rehabilitation: Actors and parameters shaping normality, liminality and depersonalisation in a UK hospital.

Sociological concern for rehabilitation remains limited. This paper aims to contribute to rehabilitation theory. It examines two units of a specialist rehabilitation hospital in the UK (amputee and neurological services) by focusing on the key actors involved - families, patients, staff - and the parameters shaping their relationships. The findings extend previous theoretical understandings of rehabilitation in three themes: normality, liminality and depersonalisation. We argue, first: normality is constantly negotiated amongst the different actors. This complicates existing works' critique of rehabilitation as reproducing the ideology of normality. Second, discourses produced during acute care shape the inpatient rehabilitation experience. This calls attention to the pre-rehabilitation phase and complicates existing works' emphasis on the transition from inpatient stay to the time of discharge. Finally, inpatient rehabilitation is notable in rendering the adverse effects of depersonalisation apparent. It combines the bureaucracy of a regular hospital ward, with institutionalising aspects of long-term care. These findings have a potential to enhance practice as well as knowledge. We call for a deeper sociological attention, combining theory-building with empirical data for a better understanding of inpatient rehabilitation.

A cross-sectional self-assessment of burnout amongst a sample of doctors in Ghana.

BACKGROUND: The occurrence of burnout amongst African health professionals has been widely anticipated, but there is a dearth of published data, especially amongst doctors. Burnout has been reported to be as high as 53% amongst doctors in the United States. If not detected, it can result in prescription errors, work-related accidents, substance abuse and depression. AIM: The aim of this study was to determine the prevalence of burnout and its associated factors amongst a sample of physicians in Ghana. SETTING: This study was conducted in Kumasi amongst physicians attending a conference organised by the West African College of Physicians, Ghana Chapter. METHOD: A cross-sectional study. Of the 90 physicians who registered for the conference, 60 responded to a self-administered Maslach Burnout Inventory questionnaire. Data were analysed descriptively and inferentially using STATA® version 14. RESULTS: Approximately 52% of respondents had been in medical practice for 10-19 years (mean 15.4 years). All the major medical specialties were represented. Internal Medicine had the highest number of participants (48.3%). With respect to the components of burnout, 5.5% of respondents experienced depersonalisation, 7.8% had a lack of personal achievement and 10.8% experienced emotional exhaustion. The association between burnout and age, sex, years of practice and clinical specialty was not found to be statistically significant. CONCLUSION: This pilot study has shown burnout to be common amongst physicians in Ghana. It is recommended that further studies are conducted, involving a larger cross-section of doctors in various parts of Africa.

Symptoms of depersonalisation/derealisation disorder as measured by brain electrical activity: A systematic review.

Depersonalisation/derealisation disorder (DPD) refers to frequent and persistent detachment from bodily self and disengagement from the outside world. As a dissociative disorder, DPD affects 1-2 % of the population, but takes 7-12 years on average to be accurately diagnosed. In this systematic review, we comprehensively describe research targeting the neural correlates of core DPD symptoms, covering publications between 1992 and 2020 that have used electrophysiological techniques. The aim was to investigate the diagnostic potential of these relatively inexpensive and convenient neuroimaging tools. We review the EEG power spectrum, components of the event-related potential (ERP), as well as vestibular and heartbeat evoked potentials as likely electrophysiological biomarkers to study DPD symptoms. We argue that acute anxiety- or trauma-related impairments in the integration of interoceptive and exteroceptive signals play a key role in the formation of DPD symptoms, and that future research needs analysis methods that can take this integration into account. We suggest tools for prospective studies of electrophysiological DPD biomarkers, which are urgently needed to fully develop their diagnostic potential.

Prevalence of burnout among nurses working at a psychiatric hospital in the Western Cape.

BACKGROUND: Nurses are exposed to stress when working in the mental health care environment. This may be because of nurses being frontline health care providers. They develop close interpersonal relationships with mental health care users (MHCUs), which is inherent in the type of care that is provided. Mental health nursing may therefore be demanding and stressful, which could render mental health nurses susceptible to burnout. OBJECTIVES: To determine the prevalence of burnout among nurses working at a selected psychiatric hospital in the Western Cape. METHODS: A quantitative, descriptive, survey design, by using simple random sampling was used to select 198 nurses employed at a psychiatric hospital in the Western Cape, South Africa. Maslach Burnout Inventory-Human Services Survey measuring emotional exhaustion, depersonalisation and personal accomplishment was used to collect the data. Domain scores were calculated, and the influence of the demographic variables on the domains was tested with independent samples Kruskal-Wallis tests and Mann-Whitney U tests. RESULTS: The study had a 100% response rate. Most of the respondents experienced low emotional exhaustion, low depersonalisation and high personal accomplishment. Enrolled nursing assistants reported significantly higher emotional exhaustion than did the advanced psychiatric nurses and professional registered nurses. Respondents with more than 5 years of experience scored significantly higher in depersonalisation. No respondents met the criteria for burnout on all three domains. CONCLUSION: Maintaining a safe working environment with adequate nursing staff is recommended. Strategies to prevent burnout in the future include the provision of resources and the promotion of open communication between staff and management.

Burnout and its prevalence among public health nurses in Ireland.

This paper presents the findings from an analysis of survey data which was collected from public health nurses (N = 136) as part of a larger study with more than 4000 nurses and midwives in Ireland. The purpose of the study was to examine the prevalence of burnout using the Oldenburg Burnout Inventory and to compare relationships between burnout, demographic and work characteristics across this group of nurses. Younger PHNs were most likely to report feeling burnout (68%) compared with those aged 51 or over (47%) who reported the lowest levels. PHNs whose highest level of qualification was a primary degree were least likely to report feeling burnout (31%) compared with those who held a Masters / Doctoral degree (54.5%). PHNs who reported working on a fixed-term full-time contract were most likely to report feeling burnout (70%) compared with those who were on a permanent part-time contract (49%). Quantitative analysis, using both descriptive and inferential statistics, was carried out and the findings show that PHNs reported moderate levels of burnout. The findings also show that burnout among PHNs is strongly correlated with the physical demands placed on individuals during work, having constant time pressures, too much being expected of individuals, the work environment being too demanding and dissatisfaction with the physical conditions.
