Recent evidence suggests that indirect verbal exposure to traumatic events can be sufficient to cause intrusions and other posttraumatic stress symptoms. In this study, we used a verbal trauma report to experimentally induce intrusions and a tactile task to manipulate the putative processes underlying intrusion development. Our findings indicate that the verbal report indeed induced intrusive recall. Moreover, the verbal report induced negative mood, state anxiety, and state dissociation, with mood and state dissociation predicting intrusion development. Additionally, the tactile task interfered with intrusion formation as indicated by the primary diary measure, but not the retrospective self-report. However, these results await further replication as this and previous trials suffered from limited statistical power. The findings support the reports by trauma therapists who experience secondary traumatization. They also challenge the assumption that all intrusions develop bottom-up from low-level sensory input via sensory representations. Future studies should explore differential processes for intrusion development based on their modality.

Existing research on the relationship between intimate partner violence (IPV) and cigarette smoking primarily involves low-risk, physical IVP-focused studies on community women. As a result, the risks associated with cigarette smoking in women victims of severe IPV have not been fully explored. This study examined the association between exposure to different forms of childhood maltreatment, exposure to physical, psychological, and sexual IPV, and current psychological distress symptoms with cigarette smoking in a high-risk sample of women victims of police-reported severe IPV. Participants included 162 women victims of police-reported severe IPV recruited in shelters for domestic violence and Child Protective Services in Portugal. Participants provided self-reports on childhood maltreatment physical, psychological, and sexual violence), physical, psychological, and sexual IPV, psychological distress symptoms (anxiety, depressive, somatic, and posttraumatic stress disorder symptoms), and daily cigarette consumption. Results revealed significant associations between daily cigarette consumption and exposure to IPV, physical abuse during childhood, psychological IPV, and anxiety symptoms in women experiencing police-reported severe IPV. Childhood maltreatment may increase vulnerability for emotion dysregulation, promoting addictive behaviors to regulate distress. Smoking can be an unhealthy regulating strategy to reduce the distress related to chronic exposure to psychological IPV. Future effective health promotion interventions in women facing severe forms of IPV may target emotional regulation and incorporate a trauma-focused approach.

There is little published research on dissociative experiences among transgender people, and none from an in-depth qualitative perspective. In-depth, open-ended interviews (N = 7, 6 trans women, 1 trans man) were conducted to explore how dissociation is experienced (particularly among trans women) and its possible relation to negative emotions. There were several similarities across the dissociative experiences described by participants: six felt themselves disconnected from their body as a whole (in contrast to feeling disconnected to a specific body part), and from the world around them and/or themselves. Four acted out different personalities, and five felt emotionally numb when they were dissociating. Six participants described that their dissociation lessened after they started hormone therapy. Respondents tended to distinguish between dysphoric and dissociative experiences: dysphoric phenomena were more clearly distressful while dissociative ones were more emotionally numb.

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).

Previous studies have suggested that psychiatrists undergo posttraumatic growth after experiencing patient suicide. However, research remains scant on the posttraumatic growth of psychiatrists who have experienced patient suicide. Thus, this study examined the factors associated with the posttraumatic growth of psychiatrists who have experienced patient suicide. The sample comprised 39 psychiatrists, and data were collected through an online self-report survey. The data collected were analyzed using descriptive statistics, frequency analysis, Pearson's correlation analysis, and Mann-Whitney U tests. Study results demonstrate that being older, having more clinical experience, having more experience with patient suicide, and receiving supportive supervision were associated with higher levels of posttraumatic growth among psychiatrists who have experienced patient suicide. However, higher levels of posttraumatic stress were associated with lower levels of posttraumatic growth. In conclusion, there is a need to increase support for psychiatrists who have experienced patient suicide to help them overcome occupational trauma and enhance posttraumatic growth. This study suggests several policy and practical implications for enhancing the posttraumatic growth of psychiatrists.

The dissociative subtype of posttraumatic stress disorder (PTSD-DS) denotes a severe type of PTSD associated with complex trauma exposure and psychiatric comorbidity. Refugees may be at heightened risk of developing PTSD-DS, but research is lacking. This cross-sectional study aimed to examine PTSD-DS and its demographic, trauma-related, and clinical correlates among a convenience sample of refugee patients over 18 years old who were diagnosed with PTSD according to DSM-5. PTSD-DS (Clinician-Administered PTSD Scale for DSM-5), trauma exposure (Life Events Checklist for DSM-5) and general psychopathology (Brief Symptom Inventory) were assessed at intake. T-tests, chi-square tests, and logistical regression analysis were conducted. The final sample consisted of 552 participants (177 (32.1%) women; 375 (67.9%) men; average age 40.0 years (SD = 11.2)) who originated from 63 countries. Of those, 158 (28.6%) met criteria for PTSD-DS. Participants with PTSD-DS scored significantly higher on PTSD symptom severity (t(550)=-5.270, p < .001), number of traumatic event types (t(456)=-3.499, p < .001), and exposure to sexual assault (χ(1) = 6.471, p = .01) than those without PTSD-DS. The odds of having PTSD-DS increased by 14.1% with exposure to each additional traumatic event type (OR = 1.141, CI 0.033-1.260). In conclusion, around 29% of adult treatment-seeking refugees with PTSD met the criteria for PTSD-DS. Those exposed to multiple traumatic event types including sexual assault, regardless of sex, were especially at risk. Having PTSD-DS was associated with more severe PTSD. Prioritizing trauma-focused treatment for those with PTSD-DS is recommended.

Though sexual violence can impact people across genders, sexual orientations, ages, and incomes, societal inequities can increase the risk of experiencing sexual violence. Such inequities are often intersectional in nature (e.g., racism and sexism) and may impact a person's ability to engage in help-seeking for experiences of sexual violence, especially among those who perceive themselves to be a burden on others or society as a whole. Therefore, the purpose of the current study was to examine the association between experiencing sexual violence, intersectional oppression, and perceived burdensomeness on barriers to help-seeking among Black American young adults. Participants (n = 289) completed an online questionnaire assessing constructs of interest. We found that half of our sample experienced any sexual violence and nearly three-fourths experienced more than one form of intersectional oppression (e.g., racism, sexism, and homophobia). Ultimately, we found that sexual violence and perceived burdensomeness - but not intersectional oppression - were correlates of experiencing barriers to help-seeking. Through incorporating multiple marginalized identities beyond Black race, our findings can expand our understanding of barriers to help-seeking among diverse Black sexual violence survivors, while revealing a new area for practitioners, healthcare providers, social workers, and related professionals to focus intervention strategies on: perceived burdensomeness. These findings are relevant to all who care for the health and well-being of those who have experienced sexual violence, chronic stress (due to singular and multiple forms of discrimination), and/or other traumas.

Dissociation is a widespread difficulty among patients suffering from Posttraumatic Stress Disorder (PTSD). However, there is no gold standard treatment for dissociative symptoms. Recent studies propose a cognitive and behavioral conceptualization for dissociation. The aim of this study was to explore the efficacy of a group program of Dissociation-Focused Cognitive Behavior Therapy (DF-CBT) on dissociative symptoms. We recruited 27 patients suffering from a dissociative subtype of PTSD in a university hospital trauma center. Participants completed questionnaires evaluating dissociation, PTSD, mindfulness abilities, beliefs about emotions, beliefs about dissociation, emotion regulation difficulties, anxiety and depression. Following an initial evaluation, participants undertook 7 sessions of DF-CBT, and were reevaluated after the last session using the same questionnaires. We found a significant reduction of dissociative, PTSD, anxiety, and depression symptoms following DF-CBT. The effect size was noticeable for all variables (.61
