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.

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.

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.

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.

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.

This study examined the relationship between childhood trauma, dissociation, and mentalization. Childhood trauma has been understood to affect both dissociation and mentalization, but it is unclear how these processes interact amidst the presence of childhood trauma. Specifically, the study sought to determine whether hypermentalization or hypomentalization would mediate the relationship between childhood trauma and dissociation. Mentalization describes the ability to understand the mental states of both the self and others, and suboptimal mentalization occurs when an individual experiences hypermentalizing, understood as a high level of certainty about mental states, or hypomentalizing, understood as a high level of uncertainty about mental states. 100 participants completed self-report measures assessing their experiences of childhood trauma using the Early Trauma Inventory Short Form Revised, dissociation using the Dissociative Experiences Scale II, and mentalization capacities using the Reflective Functioning Questionnaire. A series of mediation analyses were conducted, and it was found that neither hypermentalization or hypomentalization mediated the relationship between childhood trauma and dissociation. However, additional analyses revealed that dissociation mediated the relationship between childhood trauma and hypermentalization. The implications of the findings are explored and discussed within the context of the current literature, and the relationship between dissociation and mentalization is considered.

Ideas of reference (IR) - self-attributions about what happens in the social environment are a frequent phenomenon present in a wide variety of people with mental health disorders as well as in the nonclinical population. The purpose of this study was to find out the relationship between traumatic childhood experiences, IR and dissociative states in the nonclinical population, emphasizing the potential mediating role of dissociation between traumatic experiences and IR. The sample was comprised of 337 participants from the general population (58.8% women) with a mean age of 33.20 years (SD = 14.08). They filled in the Juvenile Victimization Questionnaire (JVQ), the Dissociative Experiences Scale-II (DES-II) and the Referential thinking Scale (REF). The results supported the original hypotheses and showed that the participants with higher frequency of IR reported more childhood traumatic (χ² (2) = 64.33, p < .001, f = .39, 1- β = .99) and dissociative experiences (χ² (2) = 50,414, p < .001, f = .38, 1- β = .99), and that dissociative states (β = .12, p < .05; 95%CI [.07, .19]; c´ = .26, p < .001), specifically absorption (β = .09, p < .05; 95% CI [.03, .15]; c´ = .26, p < .001), mediated between traumatic childhood experiences and referential thinking. It was concluded that the relationship between traumatic experiences and IR is complex and may be mediated by variables such as dissociation.
