Anomalous strange-face illusions (SFIs) are produced when mirror gazing under a low level of face illumination. In contrast to past studies in which an observer's task was to pay attention to the reflected face and to perceive potential facial changes, the present research used a mirror gazing task (MGT) that instructed participants to fixate their gaze on a 4-mm hole in a glass mirror. The participants' eye-blink rates were thus measured without priming any facial changes. Twenty-one healthy young individuals participated in the MGT and a control panel-fixation task (staring at a hole in a gray non-reflective panel). The Revised Strange-Face Questionnaire (SFQ-R) indexed derealization (deformations of facial features; FD), depersonalization (bodily face detachment; BD), and dissociative identity (new or unknown identities; DI) scales. Mirror-fixation increased FD, BD, and DI scores compared to panel-fixation. In mirror-fixation, FD scores revealed fading specific to facial features, distinct from "classical" Troxler- and Brewster-fading. In mirror-fixation, eye-blink rates correlated negatively with FD scores. Panel-fixation produced low BD scores, and, in a few participants, face pareidolias as detected on FD scores. Females were more prone to early derealization and males to compartmentalization of a dissociative identity. SFQ-R may be a valuable instrument for measuring face-specific dissociation (FD, BD, DI) produced by MGT. Use of MGT and panel-fixation task for differential diagnoses between schizophrenia and dissociative identity disorder is discussed.

Introduction: The relationship between dissociation and cognitive abilities remains controversial. Empirical studies have reported positive, negative and non-existent associations between dissociation and cognition. These inconsistent results may be due to the fact that the studies focused mainly on trait dissociation, while dissociation is not stable but transient. After validating the French version of the Clinician Administered Dissociative States Scale (CADSS), the aim of the present study was to evaluate the relationship between state dissociation and cognitive abilities.

Method: We recruited 83 patients suffering from post-traumatic stress disorder (PTSD) and assessed them twice. At T1, they performed a neutral Stroop task and a neutral binding task. At T2 (one to three weeks later), after a script-driven dissociative induction, they performed an emotional Stroop task and an emotional binding task. Between the two sessions, they completed questionnaires at home evaluating PTSD severity, trait dissociation and cognitive difficulties. State dissociation was assessed at T1 and T2 using the Clinician-Administered Dissociative States Scale (CADSS).

Results: We found good psychometric properties of the French version of the CADSS. After inducing dissociation, significantly lower attentional performance was found among patients with than without dissociative reactions. We found a significant positive correlation between state dissociation and increased attention and memory difficulties after induction.

Conclusion: The French version of the CADSS is a reliable and valid tool to assess state dissociation, which is correlated with attentional difficulties. Attentional training is recommended to help patients control dissociative symptoms.

Some evidence in non-clinical groups suggests that the relationship context in which dissociation is experienced might moderate its association with shame. The current study used vignettes detailing either dissociative symptoms or the expression of sadness occurring in three different relationship contexts: with a friend, an acquaintance, or when alone. Ratings of emotional (e.g. shame, anxiety) and behavioral (e.g. leave, talk) reactions were made on single-item measures, and shame feelings were further assessed with the State Shame Scale. Participants were in treatment for either dissociative identity disorder (n = 31) or other specified dissociative disorder (n = 3; N = 34). Feelings of shame were elevated in the acquaintance condition compared to when with a close friend or alone regardless of whether dissociation or sadness was experienced. In the acquaintance context, participants exposed to dissociation or sadness reported feeling annoyed at themselves, having a greater desire to leave, and a lesser desire to talk compared to when these experiences happened with a close friend or alone. Results suggest those with a dissociative disorder appraise themselves as more vulnerable to shame if experiencing dissociation or sadness when with an acquaintance, potentially because the risk of not being understood and rejected is heightened.

To explore individuals' personal narratives of perceived betrayals and injustices committed by institutions, their representatives, or other authority figures and discern in what spheres of life they commonly manifest. 157 adults from largely rural, low-income communities in southern Appalachia participated in semi-structured qualitative interviews that asked them to describe key points in their life experiences, including high points, low points, and turning points. These were reviewed for episodes of institutional betrayals. Interview transcripts were analyzed using a grounded thematic analysis. Participants mentioned numerous instances of betrayals that occurred from interactions with institutions or their representatives. These were grouped into four categories: professional betrayals involving mistreatment from an employer, health care provider, or other authority figure; professional-organizational betrayals where a professional perpetrator was able to get support from a problematic organizational culture; corporate malfeasance involving misdeeds by business entities; and systemic injustices involving the sociopolitical architecture of society. The findings identified a range of institutional betrayal experiences that were unnecessary, unwanted, intentional, and harmful. They could be distinguished by the type of perpetrators and often led to notable harms, including unwanted system involvement and unemployment. Although participants seldom explicitly mentioned the rural setting in their descriptions of institutional betrayal, it is likely that limited options for health care providers, schools, and other institutions exacerbated some harms. Institutional betrayals need to be considered in people's trauma dosage, their cumulative lifetime burden of trauma.

Despite prevalent trauma exposure among patients seeking health care, as well as widespread frameworks for enacting trauma-informed care, the uptake of trauma-informed practices such as trauma screening and referral among health-care providers remains relatively low. The current study sought to assess the roles of health-care providers' personal histories of adverse childhood experiences (ACEs) and personal beliefs in the just-world hypothesis in understanding their attitudes toward trauma-informed care. Advanced practice graduate nursing students (N = 180; M age = 34.6 years) completed a self-reported survey assessing their personal history of ACEs, global belief in a just world, and attitudes related to trauma-informed care. Results indicated the relation between providers' ACEs and attitudes toward trauma-informed care was fully mediated by their beliefs in a just world, such that providers reporting higher ACEs scores also report greater endorsement of attitudes consistent with trauma-informed care due to less belief in a just world. Implications for both health-care providers' themselves and cultural shifts necessary for provision of trauma-informed health care are discussed.

Appraisal of trauma is a critical factor in the development of impairing post-traumatic stress symptoms, such as dissociation. Individuals may appraise trauma as morally injurious (i.e., moral injury exposure [MIE]) and experience subsequent moral distress related to this exposure (i.e., moral injury distress [MID]). To date, however, investigation into the relations between moral injury appraisals and dissociation has been limited, particularly within community populations. This study investigated MIE and MID in relation to six facets of dissociation (disengagement, depersonalization, derealization, memory disturbances, emotional constriction, identity dissociation) in a sample of trauma-exposed community members (n = 177, 58.2% Black, 89.3% female) recruited from a public hospital and/or community advertisements. Participants completed measures assessing trauma exposure, MIE, MID, dissociation, and posttraumatic stress disorder (PTSD) symptoms. Partial correlation analyses revealed that after controlling for PTSD symptoms, MIE was correlated with disengagement, r = .23, p ≤ .025, and depersonalization, r = .25, p ≤ .001, and MID was correlated with depersonalization, r = .19, p ≤ .025. Sex moderated each association, with stronger associations observed for female participants. Findings suggest that moral injury appraisals are linked to more severe dissociative symptoms among female civilians, and as such, may need to be specifically targeted in empirically supported treatments.

Indigenous peoples in the U.S. have the highest rates of violence against women, disproportionate representation in the child welfare system, and exorbitant amounts of traumatic injuries among all ethnic groups within the U.S. yet discussions of trauma and violence against Native communities fail to consider the ongoing influence of settler colonialism. Too often trauma-focused work takes an individualist approach while policy work focuses on the collective, leading to a siloed approach in which micro-trauma work misses policy influences and in which policy work fails to seriously consider the ongoing trauma and violence experienced by Native Nations. Through the application of three Indigenous theoretical models that account for both historic and ongoing colonial influence, this work introduces relevant issues in the policy landscape of reproductive justice for Indigenous communities that are essential for trauma scholars and practitioners to understand.
