Avoidance Coping Partially Accounts for the Relationship Between Trauma-Related Shame and PTSD Symptoms Following Interpersonal Trauma

Shame and Emotion Dysregulation as Pathways to Posttraumatic Stress Symptoms Among Women With a History of Interpersonal Trauma

Women who have survived interpersonal trauma are at elevated risk of developing posttraumatic stress disorder (PTSD), and potentially modifiable factors that may be targeted in treatment warrant further investigation. This study examined a pathway from interpersonal trauma to PTSD symptoms via emotion dysregulation and shame in a large non-clinical sample of women. The sample comprised 380 women, aged 18 to 59 years (M = 31.70, standard deviation = 10.06), all of whom had a history of interpersonal trauma. Participants completed the Experience of Shame Scale, the Difficulties in Emotion Regulation Scale-Short Form, and the Life Events Checklist for DSM-5. A serial and parallel process model with interpersonal trauma as a predictor of PTSD symptoms, emotional dysregulation and facets of shame as intermediary variables, was analyzed using Statistical Package for Social Sciences Statistics PROCESS Model 81with bias-corrected bootstrap tests of indirect effects. Non-interpersonal trauma was included as a covariate. Interpersonal trauma, emotion dysregulation, and characterological and bodily shame were significantly and directly associated with PTSD symptoms, together explaining 59% of the variation in PTSD symptoms. While emotion dysregulation was associated with behavioral shame, interpersonal trauma was not associated with behavioral shame, nor was behavioral shame associated with PTSD symptoms. Tests of indirect effects supported a pathway from interpersonal trauma to PTSD symptoms via emotion dysregulation and characterological and bodily shame. These findings suggest interventions that are particularly effective at reducing emotion dysregulation and characterological and bodily shame, such as compassion and acceptance-based approaches, may complement evidence-based PTSD interventions when working with women who have survived interpersonal trauma.

Trauma-related shame predicts daily non-medical prescription opioid use among individuals with PTSD symptoms

Non-medical prescription opioid use (NMPOU) is the use of opioids without a prescription or in a way different from how they were prescribed and is the fourth most common type of drug use in the United States. Separate research has shown that trauma-related shame is linked to posttraumatic stress disorder (PTSD) and, respectively, opioid use. However, no study to date has empirically examined the association between trauma-related shame and NMPOU among individuals with PTSD symptoms. Forty adults with clinical or subclinical PTSD who reported engaging in NMPOU at least one day in the prior month before the study completed 28 days of daily surveys. Trauma-related shame was measured at baseline. NMPOU and underlying motives to engage in NMPOU were assessed once daily via a smartphone app. Twenty-four participants (60 %) reported NMPOU over the 28-day period. After controlling for PTSD symptoms and covariates, mixed models showed that higher trauma-related shame significantly predicted higher risk of daily NMPOU (B = 0.06, SE = 0.03, t = 2.14, p=.03). After controlling for false discovery rates, trauma-related shame also significantly predicted NMPOU due to the following motives (p's < 0.031): to manage depression/sadness, to manage anxiety, to manage other stress/worry, and to get high. Among individuals with PTSD, higher baseline trauma-related shame prospectively and positively predicted greater NMPOU over a four-week daily monitoring period. Findings suggest a need to attend to trauma-related shame and its impact on subsequent motivations to engage in NMPOU. Future research should examine how treatments may effectively target trauma-related shame to reduce NMPOU and more severe PTSD symptoms.

Women, Addictions, Mental Health, Dishonesty, and Crime Stigma: Solutions to Reduce the Social Harms of Stigma

British drug policies could underserve women with treatment needs, and this paper provides evidence that communication through the words and actions of professionals across drug and alcohol services, health and mental health, social work and the criminal justice sector can leave women feeling stigmatised and failed. Women live with the stigma of 'the lying addict'; however, documents and courtroom statements provided by professionals can misrepresent women's experiences, which exacerbates social harm. Data are drawn from feminist participatory action research, where female lived experience experts worked alongside academics to implement a qualitative study using interviews and focus groups with women using treatment services (n = 28) and an online world café with professionals working with these women (n = 9) and further professionals providing support at lived experience data collection events (n = 5). This data set is cross-referenced with one-to-one and small-group interviews with professionals in the field (n = 17) conducted by a third-sector partner. Findings establish that stigma negatively impacts the identification of treatment needs and access to timely and appropriate service delivery. Social harms to women with addictions could be significantly reduced with timely, authentic, honest, gender-informed and trauma-informed practices for girls and women using drugs and alcohol to self-medicate from traumatic experiences.

Association of adverse childhood experiences and cortical neurite density alterations with posttraumatic stress disorder symptoms in autism spectrum disorder

Background

Posttraumatic stress disorder (PTSD) can be a source of significant social and daily distress in autism spectrum disorder (ASD). Compared to typically developed (TD) individuals, people with ASD are at an increased risk of adverse childhood experiences (ACEs), which can result in abnormal neuronal development. However, whether or how ACEs influence abnormal neural development and PTSD symptoms in ASD has not been fully elucidated.

Methods

Thirty-nine TD individuals and 41 individuals with ASD underwent T1-weighted magnetic resonance imaging and neurite orientation dispersion and density imaging (NODDI), with axonal and dendritic densities assessed in terms of the orientation dispersion index and neurite density index (NDI), respectively. Voxel-based analyses were performed to explore the brain regions associated with PTSD symptoms, and the relationships between the severity of ACEs and PTSD symptoms and NODDI parameters in the extracted brain regions were examined.

Results

There was a significant positive association between PTSD symptom severity and NDI in the bilateral supplementary motor area; right superior frontal, left supramarginal, and right superior temporal gyrus; and right precuneus in the ASD group, but not in the TD group. ACE severity was significantly associated with NDI in the right superior frontal and left supramarginal gyrus and right precuneus in the ASD group. Moreover, NDI in the right precuneus mainly predicted the severity of PTSD symptoms in the ASD group, but not the TD group.

Conclusion

These results suggest that ACE-associated higher neurite density is of clinical importance in the pathophysiology of PTSD symptoms in ASD.

Trauma-Related Shame Mediates the Associations Between Self-Blame, Bisexual Minority Stress, and Rape-Related PTSD Symptoms

Bisexual women experience higher rates of rape and post-traumatic stress disorder (PTSD) prevalence compared to heterosexual and lesbian women. In addition, bisexual women experience unique antibisexual stigma and minority stress, which are associated with post-trauma outcomes. The aim of the current study was to test trauma-related shame as a mechanism in the relations of self-blame and bisexual minority stress (i.e., antibisexual stigma and internalized binegativity) with rape-related PTSD symptom. The sample consisted of 192 cisgender bisexual women (ages 18-35 years) who reported an experience of rape since the age of 18. Results from path analysis conducted in Mplus indicated that trauma-related shame mediated the link between self-blame and rape-related PTSD severity, as well as the links from antibisexual stigma and internalized binegativity to rape-related PTSD severity. There was also an indirect serial effect from antibisexual stigma to internalized binegativity to shame to PTSD severity. Thus, findings highlight the mechanistic role of trauma-related shame in rape-related PTSD symptoms. We identified two risk pathways: (a) general/universal risk from self-blame about rape and shame to PTSD severity and (b) group-specific risk from bisexual minority stress and shame to PTSD severity. Results indicate that reducing trauma-related shame may be an important target to improve post-rape outcomes. Finally, stigma associated with rape and sexual violence as well as antibisexual stigma must be eradicated to improve post-trauma outcomes among bisexual survivors.

Initial testing of components of the cultural determinants of trauma recovery (CDTR) theory amongst American Gender-Based violence survivors: Structural equation modelling

AIM

We tested key hypotheses derived from the Cultural Determinants of Trauma Recovery Theory (CDTR) with an American sample.

DESIGN

A cross-sectional study using anonymous online surveys.

METHODS

This study was conducted with 225 American survivors of gender-based violence (GBV) between August to November 2019. Demographics, distress (depression: PHQ8; PTSD: PCL-5), mental health service utilization (counselling and medication), sense of coherence (SOC), internal barriers to help-seeking (shame, frozen and problem management subscales: BHS-TR Internal) and the GBV healing (GBV-Heal) were used. Structural equation modelling (SEM) was conducted to test the hypotheses.

RESULTS

The final SEM model showed that the relationship between distress and mental health service utilization was not mediated by internal help-seeking barriers; the relationship between distress and trauma healing was partially mediated by internal help-seeking barriers; the relationship between internal help-seeking barriers and trauma healing was partially mediated by SOC; mental health service utilization was not significantly associated with trauma healing. Overall, the relationship between distress and trauma healing was partially mediated by internal help-seeking barriers and SOC.

CONCLUSIONS

This study confirmed some hypothetical pathways between distress and trauma healing. Further research with larger and international samples should be necessary to test the overall CDTR and compare groups.

IMPACT

This study can help us focus on psychological interventions that enhance meaning and mitigate internal help-seeking barriers to promote holistic trauma recovery. Public and public contribution: The sample was gathered from a clinical population registry that alerts patients of potential research opportunities.

Negative Attributions as a Source of Vulnerability for trauma-related Shame and PTSD Symptoms

Shame is a common trauma response that is associated with the development and maintenance of PTSD. Phenomenological descriptions of shame indicate that shame arises from internal, stable and global causal attributions (negative attributions) for the precipitating event. The current study investigated whether negative attributions would be associated with higher levels of shame and PTSD, and whether shame would mediate the relationship between causal attributions and PTSD. As negative attributions may reflect a common transdiagnostic process in both depression and PTSD, it also examined whether depression would moderate this relationship. Eighty-seven participants meeting criteria for a Criterion A stressor were administered a structured PTSD diagnostic interview and a series of self-report measures. Findings indicate that shame mediated the relationship between internal, stable and global trauma-related causal attributions and PTSD symptoms. Further, depression did not moderate this relationship, indicating that negative causal attributions are associated with shame and PTSD independent of depression. Results provide empirical support for the cognitive concomitants of trauma-related shame, which raise the possibility that addressing negative attributions through cognitive therapeutic methods may be pertinent in reducing trauma-related shame. Future prospective data is needed to establish cognitive antecedents to shame.
