Dissociative Experiences Scale Research Articles

Traumatic experiences, dissociative symptoms, and alexithymia in patients with alopecia areata.

Although genetic, environmental, autoimmune, and psychological factors are believed to play a role in the onset of alopecia areata (AA), the exact cause remains unknown. This study aimed to investigate whether there are differences in traumatic experiences, dissociative symptoms, and alexithymia levels between groups. Fifty eight patients diagnosed with AA, 58 individuals with dermatological diseases thought to have a low psychosomatic component, and 58 individuals not diagnosed with any chronic disease were included in the study. All participants were assessed using the Childhood Trauma Questionnaire (CTQ-28), Dissociative Experiences Scale (DES), Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), and Toronto Alexithymia Scale (TAS-20). A Structured Clinical Interview for DSM-5 (SCID-5-CV) form was used to exclude additional psychiatric diagnoses. Mean scores on the CTQ-28 scale revealed differences between groups in terms of physical neglect and emotional neglect scores (p < 0.001; p = 0.022; p < 0.001). There were no differences in DES scores between groups (p = 0.085). When compared in terms of TAS-20 and PCL-5 scores, differences were found (p = 0.016; p = 0.024). As a result of this study, it was concluded that physical neglect and emotional neglect could play a significant role in the onset of AA. Alexithymia and traumatic stress disorder symptoms might be more prevalent in patients with AA.

Postural Responses in Trauma-Experienced Individuals

Background: Balance and proprioception are essential elements in postural control and injury prevention. Proprioception, the body’s sense of position and movement, is closely tied to balance, which depends on input from the visual, vestibular, and somatosensory systems. This article explores the link between trauma experiences and proprioceptive dysfunction, emphasizing how heightened muscle tone, dissociation, and altered sensory processing contribute to balance issues and the risk of injury. Method: The study included 48 participants, aged 18–25. Participants completed the Emotional Regulation Scale, Dissociative Experiences Scale II, and Childhood Trauma Questionnaire, after which they had to stand on a BTrackS Balance Plate while being exposed to images that are designed to evoke emotions from the OASIS image set. The balance plate software calculated outcomes of the participants’ postural sway (total sway, sway area, root mean square (RMS) to the mediolateral (ML) and anteroposterior (AP) way, and excursion to ML and AP ways). Results: Dissociative experience shows significant correlation with RMS ML when viewing positive pictures (rτ = 0.207, p = 0.045) and when viewing negative pictures again; scores with RMS ML (rτ = 0.204, p = 0.049) but also with RMS AP (rτ = 0.209, p = 0.042) and with Excursion ML (rτ = 0.200, p = 0.049) were significant. Experiences of physical abuse affected certain indicators of postural sway when viewing positive images compared to participants with no such experience (sway area: U = 374.50, p = 0.027; RMS AP: U = 383.50, p = 0.016; Excursion ML: U = 397.00, p = 0.007). Similarly, physical neglect affected postural sway during viewing of negative images (sway area: U = 366.50, p = 0.003; RMS AP: U = 371.00, p = 0.004; Excursion ML: U = 347.00, p = 0.034; and Excursion AP: U = 353.00, p = 0.010). Conclusions: The study highlights that dissociation disrupts balance in trauma survivors, especially under emotional stress which highlights the potential for motor-based treatments.

The Utilisation of Dissociative Mechanisms - Comparative Study in a Clinical and Non-clinical Population

&lt;p dir="ltr"&gt;&lt;span&gt;Dissociative experiences are common in both clinical and general populations. In this study, we had the aim to explore the presence of any differences in the utilization of dissociative mechanisms between two types of populations, namely clinical and non-clinical and also to see if within each group there are differences in the use of these mechanisms. The research group consisted of 216 participants, of which 176 (81.5%) were non-clinical participants and 40 (18.5%) participants with a clinical diagnosis. We used two questionnaires, namely the Detachment and Compartmentalization Inventory and the Dissociative Experiences Scale and a demographic data collection tool. Our results showed that clinical participants scored significantly higher than non-clinical participants on detachment, absorption and compartmentalization. The data also showed that there are significant differences between the use of detachment, compartmentalization and absorption, separately for clinical and non-clinical participants. Detachment, absorption and compartmentalization are dissociative mechanisms used by the clinical as well as the non-clinical population, with no differences between groups in terms of gender. Age appears to influence the use of these mechanisms in the non-clinical population in that they are used less with advancing age. Absorption tends to be used less by married than unmarried people in the non-clinical population. The results of our study converge towards the theory which support the idea of "healthy dissociation".&lt;/span&gt;&lt;/p&gt;&lt;div&gt;&lt;span&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

Mental health and perceived consequences in a clinical sample of women featured in video-based pornography

ContextSeveral reports have shed light on the potentially traumatic filming conditions, and violence experienced by women featured in pornography (WP). However, there is a scarcity of research on the mental health of these women, as well as the perceived consequences of participation in Video-based Pornography (VbP). MethodsThirty-six women, recruited through collaboration with WP support groups, completed an online questionnaire covering socio-demographics, pre-VbP violence experiences, and perceived consequences of their participation in VbP. Additionally, participants completed the French versions of the post-traumatic stress disorder (PTSD) Checklist for DSM-5 (PCL-5), the Dissociative Experiences Scale (DES-II), and the 13-item Beck Depression Inventory (BDI-13). ResultsThe participants had a mean age of 31.2 years (SD = 7), and the median age at first participation in VbP was 21. A majority (77.8 %) reported a lifetime experience of sexual violence before featuring in VbP. All participants reported at least one negative effect of participating in VbP, with three in four women citing cyberbullying following VbP dissemination. Additionally, participants reported a range of physical consequences such as vaginal lesions and sexually transmitted diseases. Thirty women (83 %) had a PCL-5 score over 33, indicative of probable PTSD, and 28 women (78 %) had a DES-II score of 30 or more, indicating high levels of dissociative symptoms. Furthermore, 19 women (53 %) reported a BDI-13 score over 13, suggesting potential severe depression. ConclusionThis study underscores psychosocial vulnerabilities and the presence of severe psychopathology among WP. It also documents their perceptions of negative consequences of participation in VbP, such as cyberbullying, physical injuries, and emotional distress. Further, large-scale studies are needed to substantiate these results and better understand the scale of the problem, as well as to optimize care interventions.

Adverse childhood experiences and dissociation among Italian public psychology service users

Different studies have provided evidence that adverse childhood experiences (ACEs) are associated with mental health problems as a function of racial and ethnic diversity. The aim of the present study was thus to study the association between ACEs and dissociation in a sample of Southern Italian public psychology service (PPS) users. A sample of 183 adults who requested psychotherapeutic treatment within an Italian PPS was recruited. ACEs were assessed via the Adverse Childhood Experiences Questionnaire (ACE-Q). Dissociative symptoms were assessed via the Dissociative Experiences Scale (DES-II) and the Somatoform Dissociation Questionnaire (SDQ-20). Dissociative syndromes were assessed via two scales of the Millon Clinical Multiaxial Inventory (MCMI-III): the Somatoform Syndrome (H) and the Post-Traumatic Stress Disorder Syndrome (R) scales. The most common types of ACEs in our sample were emotional neglect and emotional abuse. The number of ACEs showed a significant association with all the different measures of dissociation administered. Logistic regression analysis for the DES-II resulted in a solution made up of sexual abuse and parental separation or divorce. The regression analysis for the SDQ-20 resulted in a solution made up of emotional abuse, physical neglect, and parental separation or divorce. Sexual abuse positively predicted PTSD scale scores, while no solution was found for somatoform disorder. ACEs and dissociation were strongly associated in this study, but the nature of this association depended on the aspect of dissociation under investigation, particularly when we considered the distinction between dissociative symptoms versus syndromes. Cultural characteristics and clinical implications for public services are discussed.

The Detection of Invalid Responses Using the Dissociative Experiences Scale-V (DES-V)

ABSTRACT The Dissociative Experiences Scale (DES) is the most widely used self-report measure of dissociation but lacks a validity scale. Abu-Rus et al. (2020) created the DES-V by embedding atypical and inconsistency items in the DES, ultimately concluding that atypicality demonstrated the greatest ability to differentiate honest respondents from feigners. Among their study limitations, Abu-Rus et al. noted the homogeneous nature of their clinical group (i.e., largely comprising individuals with PTSD) and the potential need to refine the existing atypicality items for a more heterogenous dissociation population. The current study aimed to refine the DES-V by enlisting dissociation experts to improve the believability of the atypical items (while simultaneously ensuring they did not betoken any actual dissociative symptomology) and by supplementing the online sample with a clinical sample that included a broad range of dissociative disorders. Data cleaning comprised eight different techniques, to better ensure the validity of the online sample. Honest and Feigning groups completed the assessments through Amazon’s Mechanical Turk; the clinical dissociative disorder group completed hard copy versions. The atypicality scale discriminated the three groups well, with the Feigning group scoring significantly higher than both of the honest groups (online and clinical). The mean atypicality scores of the two honest groups did not differ significantly. In addition, the scale incremented over the original DES-V in a logistic regression predicting honest and feigning participants. These robust results suggest that the revised DES-V could provide researchers with a valuable tool for validating online samples with greater precision – an increasingly vital need in light of the growing reliance on online samples.

Structural Equation Modeling of Childhood Trauma and Self-Stigma in Adult Inpatients with Borderline Personality Disorder.

Child abuse and trauma are significant risk factors in the etiology of borderline personality disorder (BPD). Apart from affecting the risk of developing BPD, adverse childhood experiences seem to increase its symptoms and related disability. Self-stigma presents another common issue with equally prominent consequences for mental health. Despite being theoretically linked, the connections among childhood trauma, self-stigma, and mental health have not been explored in patients with BPD. This study aimed to provide first insights into this understudied topic. This cross-sectional study included 283 inpatients diagnosed with BPD participating in a residential transdiagnostic psychotherapeutic program. The patients completed several measurements - the Internalized Stigma of Mental Illness Scale, the Childhood Trauma Questionnaire - Short Form, the Clinical Global Impression - Severity, the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Dissociative Experiences Scale, the Sheehan Disability Scale, and a demographic questionnaire. The data was statistically analyzed using IBM SPSS and AMOS 26 programs, and bivariate correlation tests and structural equation modeling explored the hypotheses. Retrospectively reported childhood trauma positively correlated with current self-stigma. Both childhood trauma and self-stigma were also positively related to several indicators of general psychopathology and disability. The significance of these connections was subsequently confirmed by structural equation modeling, where self-stigma acted as a partial mediator of childhood trauma, general psychopathology, and disability. Self-stigma significantly mediates the relationship between childhood trauma and selected mental health symptoms among adult patients diagnosed with BPD. Longitudinal studies are necessary to explore the causality of the findings. Therapeutic and societal efforts to tackle childhood trauma or self-stigma might benefit from reflecting its broader psychosocial context.

TRANSLATION AND VALIDATION OF URDU VERSION OF BRIEF DISSOCIATIVE EXPERIENCE SCALE FOR SUBSTANCE USE DISORDER IN PAKISTAN

Objective Dissociation is a ubiquitous construct in psychology and is of high clinical relevance. The objective of this study was to translate and validate the Brief Dissociative Experience Scale (DES-B) in the Urdu language for individuals with substance use disorder (SUD). DesignThis was a cross sectional study. Place and Duration of StudyThe study was conducted with a sample of 200 individuals with SUD aged 18 and above from drug rehabilitation centres across Pakistan between July to November 2023. MethodsThis study utilized a rigorous procedure of Mapi guidelines for translation and validation of DES-B. The validation of DES-B was determined through confirmatory factor analysis. ResultsThe data was analyzed using SPSS and AMOS software and factor structure, internal consistency, composite reliability, and convergent validity of the scale were determined. Of the 200 participants, 79.0% were male. The mean age of the participants was 30.61 years (SD = 8.87) with a range between 18 to 65. The findings indicated a good model fit for a one-factor structure with 8 items (χ²/df = 2.61, p &lt; 0.00, RMSEA = 0.089, CFI = 0.908, GFI = 0.944). Moreover, the composite reliability (CR = .77), convergent validity (AVE = .31), and internal consistency (α =.76) showed favorable results. Overall, the Urdu version of DES-B demonstrated acceptable results in terms of the construct’s validity and reliability. ConclusionThe Urdu version of DES-B can be used as a reliable and valid tool to assess dissociative experiences in individuals with SUD suitable for research and clinical settings.

A Network Analytic Approach to Dissociation: New Insights from Clinical Data

ABSTRACT The transdiagnostic construct of dissociation, characterized by a disintegration of specific psychological functions such as consciousness, memory, identity, perception, body representation, and behavior, remains elusive to a unified conceptualization. Specifically, its dimensionality is a matter of ongoing controversy. Empirical approaches applying factor analyses to the Dissociative Experiences Scale (DES) have yielded inconsistent findings. This study adopts a novel methodological approach, utilizing Exploratory Graph Analysis (EGA) to address this issue. In a sample of 668 day-hospital patients undergoing psychotherapy for a variety of mental disorders, a Gaussian graphical model was estimated for the 28 items of the DES. Additionally, the stability of the results was ensured by bootstrap procedures. While both the original EGA and the bootstrap EGA suggested four dimensions, the structural consistency of this solution was low due to an instability of 12 items. After excluding 10 of these unstable items, re-analyses again revealed a four-factor structure, but boot EGA indicated that one factor had unsatisfactory structural consistency due to the multidimensionality of its two items. Upon removing these, our final network consisted of 16 items mapping onto 3 dimensions. Our study, using data from a diagnostically heterogeneous sample, replicates and extends previous findings on the dimensionality of dissociation as captured by the DES. The three dimensions identified correspond to segregated processes, derealization/depersonalization, and absorption. This solution aligns with a bipartite model of dissociation with two broader categories referring to either altered states of consciousness (often named detachment) or to non-integrated mental modules (labeled as compartmentalization).

Detecting Noncredible Responding in College Student ADHD Assessment: A Comparison of Several Brief Symptom Validity Tests

AbstractA diagnosis of attention-deficit/hyperactivity disorder (ADHD) offers tangible and psychological benefits to college students. These incentives lead some students to exaggerate symptoms on self-report rating scales. Although validity tests can detect noncredible responding, they are seldom used by clinicians who conduct adult ADHD evaluations. Many validity tests require considerable time, are expensive to administer, or are not accessible to many clinicians. We conducted a between-subjects simulation study examining the ability of several brief symptom validity tests to differentiate college students with self-reported ADHD (n = 229) and students without ADHD randomly assigned to honest control (n = 260) or simulator (n = 239) conditions. All participants completed the Conners’ Adult ADHD Rating Scales (CAARS) with several embedded validity indicators (i.e., CAARS Inconsistency Index, CAARS Infrequency Index [CII], Dissociative Experiences Scale, Exaggeration Index [EI]), and the Subtle ADHD Malingering Screener. Results showed that students without ADHD could easily simulate this condition. Simulators earned significantly higher scores than participants in the ADHD and control conditions on all the validity tests that we examined, except the CAARS Inconsistency Index. Elevated scores on the CAARS hyperactive-impulsive scale, the CII, or the EI yielded the best classification statistics with specificity to controls ranging from 98.5 to 100%, sensitivity to simulators ranging from 35.6 to 42.7%, and low positive cases among participants in the ADHD condition. Associations between these validity scales were moderate. Requiring elevated scores on multiple validity scales yielded perfect specificity to controls, sensitivities to simulators between 27.2 and 31.8%, and few positive cases among participants in the ADHD condition (0 to 3.1%). These tests may offer clinicians a time- and cost-effective way to evaluate the validity of students’ self-reports, especially when integrated with objective information from other sources.

Clinical characteristics of 217 Chinese cases with depersonalization/derealization disorder

Depersonalization/derealization disorder (DPD) is a prevalent yet inadequately understood clinical condition characterized by a recurrent or persistent sense of unreality. This study aims to provide insight into DPD through descriptive and comparative analyses involving a large group of Chinese participants. The socio-demographic details (age, gender proportion, education, occupational status, marital status), depersonalized and dissociative symptom characteristics (symptomatic factors or subscales of the Cambridge Depersonalization Scale and the Dissociative Experiences Scale), development trajectory (age of onset, potential precipitating factors, course characteristics), treatment history (duration of delayed healthcare attendance, duration of delayed diagnosis, previous diagnoses), and adverse childhood experiences of the DPD patients are presented. Comparisons of anxiety and depressive symptoms, alongside psychosocial functioning, between DPD participants and those diagnosed with generalized anxiety disorder, bipolar disorders, and major depressive disorder were conducted. The analysis highlights a higher male preponderance and early onset of DPD, symptomatology marked by derealization, notable impairment in psychosocial functioning, and prolonged periods of delayed healthcare attendance and diagnosis associated with symptom severity. Furthermore, noteworthy relationships between adverse childhood experiences and symptom levels were identified. The findings substantiate the view that DPD is a serious but neglected mental disorder, urging initiatives to improve the current condition of DPD patients.

Structure, network analysis, psychometric properties and clinical utility of the self-absorption scale in China

BackgroundSelf-absorption refers an excessive, persistent, and rigid preoccupation with information regarding the self. This study aims to introduce the Self-Absorption Scale (SAS) into China with an assessment of its latent variable structure, network structure, psychometric properties, and clinical utility in a nonclinical Chinese sample.Methods209 participants completed the translated SAS as well as the Short General Health Questionnaire (GHQ-12), rumination subscale of the Rumination-Reflection Questionnaire (RRQ), the Mindful Attention Awareness Scale (MAAS), the Private Self-Consciousness Scale (PrSCS), the Obsessive-Compulsive Inventory-Revised (OCI-R) and the Dissociative Experiences Scale (DES-II). In addition, 30 respondents completed the Chinese version of the SAS and retested it 2 weeks later.ResultsThe Chinese version of the SAS (CH-SAS) had a desirable two-correlated-factor structure with the reverse scored item removed, which was invariant across different genders. The core items in the network structure of the CH-SAS were related to excessive self-immersion, uncontrollability and anxiety aspects of self-absorption. The Cronbach’s alpha coefficient for the CH-SAS was 0.903 while the McDonald’s omega coefficient was 0.916 and the test-retest reliability was 0.908. The CH-SAS and its two subscales had moderate positive correlations with the rumination subscale of the RRQ (ranging from 0.474 to 0.616; p < .001) and the GHQ-12 (ranging from 0.479 to 0.538; p < .001), and moderate negative correlations with the MAAS (ranging from − 0.413 to − 0.360; p < .001). The PrSCS has almost no correlation with the CH-SAS and PrSAS (p > .05), and its correlation with the PubSAS was significant at the 0.05 level, with a remarkably low correlation coefficient (r = .157). The hierarchical regression analysis suggested that the CH-SAS can significantly predict the severity of OCD beyond factors such as depression, anxiety, rumination, dissociation, and mindful attention awareness.ConclusionsThe CH-SAS demonstrates excellent reliability, including internal consistency and test-retest reliability. Additionally, it exhibits favorable structural validity, as well as strong evidence of convergent and divergent validity. Furthermore, the self-absorption measured using the CH-SAS contributed significantly to the prediction of OCD beyond other relevant psychological factors, suggesting its clinical utility.

Course and Prediction of Dissociation in Patients with Borderline Personality Disorder and Personality-Disordered Comparison Subjects: A 24-Year Follow-Up Study

ABSTRACT The first purpose of this study was to determine the course of dissociation among patients with borderline personality disorder (BPD) and personality-disordered comparison subjects (OPD) over 24 years of prospective follow-up. The second purpose was to determine clinically meaningful predictors of dissociation among patients with BPD. The Dissociative Experiences Scale (DES) was administered to 290 patients with BPD and 72 personality-disordered comparison subjects at baseline, and then once every two years over 24 years of prospective follow-up. Baseline predictors were assessed with the Revised Childhood Experiences Questionnaire (CEQ-R), the SCID-I, and the Shipley Institute of Living Scale. Time-varying predictors were assessed at baseline and every subsequent two years by means of the Abuse History Interview (AHI). Patients with BPD had higher baseline dissociation scores than personality-disordered comparison subjects. Whilst dissociation decreased significantly over time for both patient groups, the BPD group showed a steeper decline. Severity of childhood sexual abuse, adult history of rape, adult history of partner violence, and IQ were multivariate predictors of dissociation among patients with BPD. Taken together, the present findings suggest that a combination of interpersonal trauma exposure and cognitive abilities may contribute to the severity of dissociation in adult patients with BPD.

Mediator Role of Dissociative Experiences in the Effect of Childhood Traumas on Emotion Regulation Difficulty and Parental Child-Containing Function.

The aim of this study is to examine the mediating role of dissociation in emotional regulation and parental child-containing function skills of mothers exposed to childhood trauma. The research was conducted with 400 mothers between the ages of 20-60 who had childhood trauma and currently have children between the ages of 0-18. The relational screening model, one of the general screening models, was used in the research. The sample of the research was selected using the convenient sampling method and the simple random method. Research data were collected with the Sociodemographic Information Form, Childhood Trauma Scale (CTS), Parental Child-Containing Function Scale (PCCFS), Emotion Regulation Difficulty Scale (ERDS), and Dissociative Experiences Scale (DES). According to the results obtained in the study, physical abuse (β = 0.197; 95% CI [0.124; 0.268]), physical neglect (β = 0.232; 95% CI [0.161; 0.306]), emotional abuse (β = 0.238; 95% CI [0.169; 0.309]), emotional neglect (β = 0.210; 95% CI [0.150; 0.275]), and sexual abuse (β = 0.139; 95% CI [0.058; 0.220]) were found to have a significant indirect effect on emotion regulation difficulties through dissociative experiences. In addition, physical abuse (β = 0.122; 95% CI [0.071; 0.181]), physical neglect (β = 0.151; 95% CI [0.084; 0.228]), emotional abuse (β = 0.158; 95% CI [0.086; 0.238]), emotional neglect (β = 0.159; 95% CI [0.093; 0.235]), and sexual abuse (β = 0.086; 95% CI [0.039; 0.150] was found to have a significant indirect effect on parental child-containing function skills through dissociative experiences.

An Investigation of Dissociative Symptoms and Related Factors in Autistic Adolescents.

Despite exposure to trauma and adverse life events being frequently reported in Autism Spectrum Disorder (ASD), few studies have examined the relationship between these factors and dissociative symptoms in the autistic population. The aim of the study is to investigate symptoms of dissociation in autistic adolescents, and to explore factors that could be associated with dissociative symptoms in ASD. This cross-sectional study involved 59 autistic adolescents between 12 and 18years old, with the mean age of 14.3 ± 1.8. Dissociation, autism characteristics, childhood traumas, peer bullying, and Post-Traumatic Stress Disorder (PTSD) symptoms were assessed using the Adolescent Dissociative Experiences Scale (ADES), the Childhood Autism Rating Scale (CARS), the Childhood Trauma Questionnaire (CTQ), the Nine-Item Child-Adolescent Bullying Screen (CABS-9), and the Child Posttraumatic Stress Reaction Index (CPTS-RI), respectively. Results from the ADES revealed that 12.5% of the participants scored above the threshold for dissociative disorders. In the linear regression model constructed to evaluate factors associated with dissociative symptoms, an increase in dissociative symptoms was statistically significantly associated with an increase in the total CTQ score (p = 0.002) and age (p = 0.006). The findings of the study indicate that dissociative symptoms may occur in autistic adolescents. It is suggested that dissociative symptoms observed in autistic adolescents may particularly be associated with childhood traumas and increasing age. Further research into dissociative symptoms in ASD is warranted, requiring larger sample sizes, specialized measurement scales, and structured interviews.

Relationships between psychotic and affective symptoms, schizotypal and dissociative phenomena, and adverse life events among individuals with psychotic disorders

Background: Psychotic symptoms and self-rated schizotypal phenomena have similar dimensional structures. Additionally, dissociative phenomena have conceptual links with psychosis/schizotypy and all of these phenotypes are associated with adverse life events (ALEs). The relationships between these factors among individuals with psychotic disorders are not well established and were investigated in this study. Method: 76 participants with any psychotic disorder were recruited from mental health services in West Yorkshire, UK. Lifetime psychotic and affective symptoms were assessed by research interviews and case record review. The self-rated Schizotypal Personality Questionnaire (SPQ) with additional questions regarding inappropriate affect, Dissociative Experiences Scale (DES), and questionnaires regarding cumulative adverse life events in childhood (CLEQ) and in the year before clinical onset (BLEQ) were also administered. Relationships between factors were assessed using Spearman correlations and linear regression analysis. Results: Correlations with relevant psychotic symptoms ranged from ~0.3 for some positive and negative SPQ subdomains to ~0 for disorganised subdomains. In contrast, SPQ and DES were highly correlated (~0.7). In univariate analysis, ALEs were associated with depression, DES, and positive and disorganised SPQ subdomains. In multivariable analysis, ALEs in childhood and before onset were independently associated with the SPQ Unusual perceptual experiences subdomain. Conclusion: Among individuals with psychotic disorders, neither SPQ nor DES questionnaire responses are likely to be useful proxies for psychotic symptoms. However, particularly questionnaire-based unusual perceptual experiences may be useful when assessing the range of phenomena associated with adverse life events.

PTSD, dissociative experiences, and depressive symptoms in a clinical sample of women who featured in pornographic productions

IntroductionThe mental health of the people who featured in Pornographic Productions (PP) is underexamined. However, PP frequently involve unsimulated violent acts mostly experienced by women. Furthermore, some women participating in PP also report being coerced into unwanted sexual acts. Therefore, featuring in a PP could be experienced as a traumatic event, and could be associated with negative mental health disorders.ObjectivesOur study examines mental health indicators among Women who have participated in at least one PP (WPP), and who consulted clinical psychologists, after referral by WPP support groups.MethodsThirty-six women were recruited by two clinical psychologists during an individual consultation. Participants completed the French versions of the post-traumatic stress disorder (PTSD) Checklist for DSM-5 (PCL-5), the Dissociative Experiences Scale (DES), as well as the 13-item Beck Depression Inventory (BDI-13). Data on socio-demographic characteristics, lifetime experience of sexual violence prior to participating in a PP, as well as the perceived effect of participating in a PP were also measured.ResultsThe mean age of participants was 31.2 (std=7), and the average age at first participation in a PP was 23.4 (std=6). The majority (78%) of participants reported lifetime experience of sexual violence prior to participation in a PP. Thirty women (83%) had a PCL5 score over 33 indicative of probable PTSD, and 28 women (78%) had a DES score of 30 or more indicating high levels of dissociation. Further, 16 participants (44%) reported a BDI-13 score over 16 indicating severe depression.ConclusionsThis study highlights the high prevalence of PTSD, dissociative experiences, and depressive symptoms in a clinical population of women who featured in at least one PP. Further studies are needed to better understand the scale of the problem and optimize care interventions.Disclosure of InterestNone Declared

Diagnosing Trauma-related Dissociative Disorders in Hungary: The Development of the Hungarian Version of MID (MID-HU)

IntroductionThe recognition, diagnostics and treatment of dissociative disorders (DD) in Hungary is currently in its infancy. According to international researches the prevalence of dissociative disorders is similar to that of the major psychiatric disorders (bipolar disorder, schizophrenia, etc.). Due to the lack of valid diagnostic tools no data is available regarding the prevalence of dissociative disorders in Hungary so far.ObjectivesTo fill this gap within our profession; to provide a complex diagnostic tool; developing the hungarian version of the Multidimensional Dissociation Questionnaire (MID-HU)Methods 341 people participated in our study classified into four groups: (1) healthy controls (n=88), (2) patients from private practice diagnosed with DD and all those participants who have DD according to their MID results (n=103), (3) hospitalized psychiatric (mixed sample, n=60) and (4) SUD patients (n=89). The questionnaire package contained the hungarian version of the Multidimensional Inventory of Dissociation (MID-HU), the Dissociative Experience Scale (DES), the Traumatic Antecendents Questionnaire (TAQ), the Self-Report Version of the Dissociative Disorders Interview Schedule (DDIS-SR) and additional questions. Now we present the first results regarding the adaptation process of the hungarian MID (MID-HU).ResultsThe mean age of the participants was 36 years, 61,6% were female and 38,4% male. The MID-HU has strong internal consistency: the alpha coefficients for the 14 facet scales were 0.88 or higher. The alpha coefficients for the 23 dissociation diagnostic scales ranged from 0,74-0,95; 9 were excellent (0,90 or above), 10 were good (0,80 or above), and 4 were fair (0,70 or above). The test-retest correlation of the Mean MID-HU scores is good (0,87). Factor analysis of the MID-HU extracted one main factor: dissociation. The mean MID-HU scores correlated with mean DES scores (0,87), indicating a good convergent validity. We found significant differences between the healthy control group and the dissociatve group in the mean DES (control: 9,5, dissociative: 27,6, Sig:&lt;0,001), mean MID (control: 2,5, dissociative: 27, Sig: &lt;0,001), the 23 dissociative diagnostics scales of the MID, 14 facet scales of the MID, and all diagnostics scales of the DDIS (using Mann-Whitney).ConclusionsThe MID-HU seems to be a valid instrument, that can differentiate between DD patients and healthy people.Disclosure of InterestNone Declared

Dissociative Identity Unveiled: A Case Report of 17 Distinct Identities Emerging in a Clear Timeline Following Trauma Events

Introduction Dissociative Identity Disorder (DID) is a complex and enigmatic mental disorder in which an individual maintains two or more distinct identities or personality states. We present a rare and captivating case report of a 27-year-old female patient who exhibited a remarkable 17 distinct identities, developed in a clear and unprecedented timeline following a series of specific traumatic events. The novelty of this case lies in the comprehensive documentation and analysis of the sequential emergence of these identities, offering valuable insights into the development and progression of DID.ObjectivesOur aim in presenting this case study is to offer a unique presentation to the constantly evolving understanding of DID. This case offers insight and provokes the need for research into the traumagenic nature of DID. This case showcases the influence on the chronological evolution of the patient’s 17 identities following a multitude of traumatic events.MethodsStructured interviews, psychiatric assessments, and psychological measurements, including self-reported measures of the Dissociative Experiences Scale, were employed to assess the identities and their individual experiences of the traumatic events. The patient was diagnosed with DID and received treatment including pharmacotherapy, psychoeducation, and trauma-focused psychotherapy. As a result of the therapeutic process, the patient was able to develop a higher sense of self-awareness and thus was able to integrate their 17 fragmented identities into a single host identity, demonstrating improvement in the functioning of interpersonal relationships.ResultsThe patient’s history reveals that the onset of her DID was linked to a traumatic event that occurred during early childhood, triggering the emergence of her first alternate identity. Over time, additional identities manifested, each appearing to serve as a coping mechanism to contend with the psychological distress stemming from subsequent significant trauma episodes. This case report meticulously outlines the chronological development of these identities and explores the distinct characteristics, behaviors, and roles assumed by each personality.ConclusionsThis case report offers valuable information on the complex development and pathogenesis of DID with a trauma influence. The presentation of this patient may lead to further research and more tailored therapeutic interventions for individuals suffering from DID.Disclosure of InterestNone Declared
