Upto 86% of dissociative individuals engage in non-suicidal self-injury (NSSI). Research suggests that people who dissociate utilize NSSI to regulate posttraumatic and dissociative experiences, as well asrelated emotions. Despite high rates of NSSI, no quantitative study has examined the characteristics, methods, and functions of NSSIwithin a dissociative population. The present study examined thesedimensions of NSSI among dissociative individuals, as well aspotential predictors of intrapersonal functions of NSSI. The sample included 295 participants who indicated experiencing one or more dissociative symptoms and/or having been diagnosed with a trauma- or dissociation-related disorder. Participants were recruited through online trauma- and dissociation- related forums. Approximately 92% of participants endorsed a history of NSSI. The most common methods of NSSI were interfering with wound healing (67%), hitting oneself (66%), and cutting (63%). After controlling for age and gender, dissociation was uniquely associated with cutting, burning, carving, interfering with wound healing, rubbing skin against rough surfaces, swallowing dangerous substances, and other forms of NSSI. Dissociation was correlated with affect regulation, self-punishment,anti-dissociation, anti-suicide, and self-care functions of NSSI;however, after controlling for age, gender, depressive symptoms, emotion dysregulation, and PTSD symptoms, dissociation was no longer associated with any function of NSSI. Instead, only emotion dysregulation was associated with the self-punishment function ofNSSI and only PTSD symptoms were associated with the anti-dissociation function of NSSI. Understanding the unique properties of NSSI among dissociative individuals may improve the treatment of people who dissociate and engage in NSSI.

This systematic review and meta-analysis aimed to investigate the relationship between dissociation and obsessive-compulsive symptoms (OCS) and disorder (OCD). Specifically, the study aimed to (a) estimate the pooled prevalence of dissociative disorders among individuals with OCD; (b) systematically review the prevalence of OCD among individuals with dissociative disorders; (c) compare the severity of dissociative symptoms between individuals with OCD and non-clinical controls; (d) estimate the association between OCS and dissociative symptoms in the clinical and non-clinical populations. A systematic search was carried out in biomedical databases from inception to January 2022 according to PRISMA guidelines. A total of 41 studies met inclusion criteria (n = 9,438, 34.3% males). The pooled prevalence of dissociative disorders in adult samples with OCD was 8% (95% CI [3, 15], k = 5). Studies on adolescent and adult patients with dissociative disorders found that 17-32% reported comorbid OCD, while a prospective study of patients with early-onset dissociative disorders found no evidence of association with OCD. Individuals affected by OCD reported more dissociative symptoms than non-clinical controls (g = .67, 95% CI [.18, 1.16], k = 9). A moderate correlation between dissociative symptoms and OCS was detected (r = .43, 95% CI [.36, .51], k = 18). Sensitivity analyses showed small/moderate correlations between dissociative experiences and specific types of obsessions and compulsions. Findings suggest that dissociative symptoms are moderately related to OCS in both clinical and non-clinical populations. Interventions aimed to reduce dissociation might improve treatment response of patients suffering from OCD.

Trauma and substance use disorders (SUDs) frequently co-occur, especially in women. Previous studies have attempted to determine if individual differences in trauma histories could be meaningfully categorized but few studies have focused solely on women, especially those reporting substance use problems. A total of 130 women (M age = 30.7, SD = 7.9) self reporting past-year substance use problems completed comprehensive measures assessing lifetime exposure to a variety of traumatic events as well as substance use patterns and severity. Using latent class analysis, three classes emerged, a Low Lifetime Interpersonal Trauma class (40%, n = 52), a Moderate Lifetime Interpersonal Trauma class (23.8%, n = 31) and a High Lifetime Interpersonal Trauma class (36.2%, n = 47). Groups did not vary on daily/almost daily use of different types of substances and polysubstance use frequency but were significantly different on SUD severity, with the Moderate and the High Lifetime Interpersonal Trauma classes reporting severe SUD severity in comparison to moderate severity for the Low Interpersonal Trauma class. The findings of the current study indicate that women experiencing substance use problems should receive SUD treatment in a trauma-informed manner but that not all may require integrated trauma and substance use interventions.

Childhood abuse puts individuals at risk for psychopathology and psychiatric symptoms such as posttraumatic stress disorder (PTSD) and anxiety symptoms. At the same time, research has indicated that some survivors report positive transformations in the aftermath of their trauma, known as posttraumatic growth (PTG). Yet the essence of PTG reports is questionable, and some scholars claim that it may reflect maladaptive illusory qualities. Furthermore, according to a recent theoretical model, PTG might be dissociation-based and related to survivors' bonds with their perpetrators. This study aimed to explore these claims by assessing PTG, dissociation, and identification with the aggressor (IWA), as well as PTSD and anxiety symptoms. An online survey was conducted among 597 adult childhood abuse survivors. Study variables were assessed via self-report measures. Analyses indicated positive associations between PTG, dissociation, and IWA. Three distinct profiles were found, reflecting high, medium, and low scores on PTG, dissociation, and IWA. Profile type explained PTSD and anxiety symptoms above and beyond gender, age, and abuse severity. These findings suggest that whereas some childhood abuse survivors might experience a positive transformation subsequent to their trauma, others' PTG reports might reflect dissociative mechanisms and pathological attachments to their perpetrators, and thus might be maladaptive.

Interactions between childhood trauma (CT) and dissociation can contribute to psychiatric disturbances. We explored this phenomenon in relation to behavioral addictions (BAs) in a sample (n = 633) of young adults (age: 18-34 years). Self-report measures investigating CT, dissociation, and symptoms related to gambling disorder, internet gaming disorder, problematic social media use, exercise dependence and compulsive buying were used. Scales related to BAs were summarized into a single measure ("Total Behavioral Addiction Index" - TBAI) for inferential analyses. A model analyzing the direct and indirect effects of CT on TBAI through the mediation of pathological dissociation was performed, controlling for confounding factors. Measures on CT, dissociation, and TBAI were significantly associated with each other (all p < .001). The total effect of CT on TBAI was significant (B = 0.063; CI: 0.045; 0.081); pathological dissociation significantly mediated such association (B = 0.023; CI: 0.013; 0.036). Our findings support the possibility that the interaction between CT and dissociation contributes to increase disturbances related to BAs.

This study examined the factor structure and psychometric properties of the Dissociative Symptoms Scale (DSS) among the Korean community adult population with adverse childhood experiences (ACE). Data were drawn from community sample data sets collected from an online panel investigating the impact of ACE and ultimately consisted of data from a total of 1304 participants. A confirmatory factor analysis revealed a bi-factor model with a general factor and four sub-factors such as depersonalization/derealization, gaps in awareness and memory, sensory misperceptions, and cognitive behavioral reexperiencing, which are the four factors that correspond to the original DSS. The DSS showed good internal consistency as well as convergent validity with clinical correlates such as posttraumatic stress disorder, somatoform dissociation, and emotion dysregulation. The high-risk group with more ACE was associated with increased DSS. These findings support the multidimensionality of dissociation and the validity of Korean DSS scores in a general population sample.

The Dissociative Experiences Measure, Oxford (DEMO) is a recently developed measure that reflects the current conceptualization of dissociation. However, psychometric investigations of the DEMO are still limited. The current study examined the factor structure and psychometric properties of the Hong Kong Chinese version of the DEMO (HKC-DEMO). Online survey data on 914 community-dwelling adults in Hong Kong was extracted from a primary preregistered study on sleep and dissociation. Confirmatory factor analyses revealed that a five-factor structure, identified as "unreality," "numbness and disconnectedness," "memory blanks," "zoned out," and "vivid internal world," fit the data adequately. The five-factor structure fit significantly better than a four-factor structure, which combined "zoned out" and "vivid internal world" as a single factor of "absorption." Furthermore, the HKC-DEMO demonstrated excellent reliability, and satisfactory convergent, and divergent validity. The current study was the first to translate the DEMO to other language and showed that the HKC-DEMO is reliable and valid for use in Hong Kong Chinese adults. Further validation of the HKC-DEMO with a clinical sample and samples with a wider age range would enhance the generalizability of the HKC-DEMO.

Our ability to regulate our emotions plays a key protective role against psychological distress and somatic symptoms, with most of the literature focusing on the role of cognitive reappraisal in interventions such as cognitive behavioral therapy (CBT). This study seeks to examine the relationship between emotion dysregulation and psychological and physical distress in university students through the role of depersonalization (DP) and insecure attachment. This study will try to explain the deployment of DP as a defense mechanism to insecure attachment fears and overwhelming stress, developing a maladaptive emotion responding strategy, which affects wellbeing later in life. A cross-sectional design was used on a sample (N = 313) of university students over the age of 18 which consisted of an online survey of 7 questionnaires. Hierarchical multiple regression and mediation analysis were conducted on the results. The results showed that emotion dysregulation and DP predicted each variable of psychological distress and somatic symptoms. Both insecure attachment styles were found to predict psychological distress and somatization, mediated through higher levels of DP, whereby DP may be deployed as a defense mechanism to insecure attachment fears and overwhelming stress, which affects our wellbeing. Clinical implications of these findings highlight the importance of screening for DP in young adults and university students.

Chronic pelvic pain (CPP) is associated with a history of trauma and symptoms of somatoform dissociation. We aimed to describe how somatoform dissociation impacts CPP symptoms, surgical treatment, and health-related quality of life (HRQOL). Patients (N = 133) diagnosed with CPP presenting for an appointment at a women's health clinic between November, 2019 - July, 2021 were recruited to participate in a cross-sectional study and complete a survey assessing symptoms of somatoform dissociation, post-traumatic stress disorder (PTSD), pelvic pain severity, history of CPP-related surgeries, and mental and physical HRQOL. We also conducted a post-hoc analysis assessing correlations of individual symptom items on the Somatoform Dissociation Questionnaire (SDQ-20) with HRQOL outcomes. We did not find a relationship between somatoform dissociation and pelvic pain severity or surgical history. Physical HRQOL outcomes were related to somatoform dissociation, PTSD symptoms, and pelvic pain severity, while mental HRQOL outcomes were connected to somatoform dissociation and PTSD symptoms. Our study reveals preliminary evidence suggesting that among CPP patients, HRQOL outcomes are affected by unique profiles of positive and negative symptoms of somatoform dissociation, including sensory disturbances, localized genital pain, and generalized numbness and bodily analgesia. Addressing specific symptoms of somatoform dissociation may enhance HRQOL among trauma-exposed women with CPP. Replication studies are needed to validate our findings. Integrating trauma-informed approaches, including standardized evaluations of trauma exposure and symptoms of somatoform dissociation into routine care for women with CPP is encouraged.
