Prolonged exposure treatment for post-traumatic stress disorder: Single case studies in a sample of adults with mild intellectual disabilities.

Post-traumatic stress disorder (PTSD) is common in adults with intellectual disabilities. Often there are additional disorders such as substance use, mood and anxiety disorders. The current study focuses on the feasibility and initial efficacy of prolonged exposure (PE) for PTSD in adults with mild intellectual disabilities. The secondary effect of PE on additional mood, anxiety and substance use disorders is also examined. A single case experimental design (N = 12) with an A (baseline)-B (intervention) phase including a follow-up measurement after 3 months was conducted. Time series and single time points measurements were performed. Six participants dropped-out. The results showed a significant decrease in PTSD symptoms and a significant decrease in additional symptoms (social avoidance, anxiety and stress), among participants who completed treatment. PE appears to be a feasible and effective treatment for PTSD in some adults with mild intellectual disabilities. Suggestions emerge from this study to make standard PE treatment more appropriate for adults with mild intellectual disabilities. Further research is needed to reduce drop-out in trauma treatment. Some suggestions for this are made in this study. Treatment of PTSD with PE did not appear to affect comorbid mood disorders. Further research is needed.

Bereavement during lockdown: the potential impact of COVID-19 restrictions on grief and post-traumatic stress disorder in a Turkish-Muslim population

ABSTRACT The current study examined whether disruption to performing Islamic death rituals could be linked to core bereavement and post-traumatic stress disorder (PTSD) symptoms in Turkish-Muslim individuals who lost their close relatives to COVID-19. Participants (n = 52) completed a Demographic Information and Bereavement Experience (DIBEF) form with items probing demographics, attendance to rituals, receiving social support, and perceived disruption to bereavement via COVID-19 restrictions. The Core Bereavement Items (CBI) and the Post-traumatic Stress Disorder Checklist-Civilian Version (PCL-C) were used to measure symptomatology. The results showed that 92.3% of the participants did not receive condolence visitors, 98.1% failed to say goodbye, and 78.8% could not practice their religious duties. Importantly, perceived disruption score was significantly linked to the CBI (but not PCL-C) scores. The potential role of perceived disruption to bereavement in aggravating the grief response is discussed in relation to the dual process model of coping with bereavement.

Cognitive processing therapy (CPT) versus individual drug counseling (IDC) for PTSD for veterans with opioid use disorder maintained on buprenorphine.

There are high rates of comorbidity between posttraumatic stress disorder (PTSD) and opioid use disorder (OUD). Evidence-based trauma-focused psychotherapies such as Cognitive Processing Therapy (CPT) are a first-line treatment for PTSD. Veterans with OUD are treated primarily in substance use disorder (SUD) clinics where the standard of care is drug counseling; they often do not have access to first-line PTSD treatments. This study tested whether CPT can be conducted safely and effectively in veterans with comorbid OUD treated with buprenorphine. This 12-week, 2-site, randomized clinical trial (RCT) included open-label randomization to two groups: (a) CPT versus (b) Individual Drug Counselling (IDC) in veterans with PTSD and comorbid OUD who were maintained on buprenorphine (N = 38). Veterans randomized to either IDC (n = 18) or CPT (n = 20) showed a significant reduction in self-reported PTSD symptoms over time as measured by the PTSD checklist (PCL-5) but there were no treatment group differences; there was some indication that reduction in PTSD symptoms in the CPT group were sustained in contrast to the IDC group. Recruitment was significantly impacted by COVID-19 pandemic, so this study serves as a proof-of-concept pilot study. Veterans with OUD and PTSD can safely and effectively participate in evidence-based therapy for PTSD; further work should confirm that trauma-focused treatment may be more effective in leading to sustained remission of PTSD symptoms than drug counseling. This is the first study to evaluate CPT for PTSD in the context of buprenorphine treatment for OUD.

Identifying candidate mechanisms of comorbidity in disordered eating and posttraumatic stress disorder symptoms among U.S. veterans: A network analytic approach.

Comorbidity between posttraumatic stress disorder (PTSD) and disordered eating (DE) symptoms is common, reflecting a possible reciprocal relationship between these disorders. Network analysis may reveal candidate mechanisms underlying their comorbidity and highlight important treatment targets. Two national samples of U.S. veterans endorsing trauma exposure self-reported PTSD and DE symptoms. The discovery sample included veterans from all service eras (n = 434). The validation sample included recently separated post-9/11 veterans (n = 507). We fit graphical lasso models to evaluate the network structure of PTSD factors based on the seven-factor "hybrid" model and DE symptoms within each sample. We used strength scores to identify the most central symptoms within the networks and identified bridge symptoms connecting PTSD and DE features. We tested for network invariance between self-identified men and women within each sample and across the studies. PTSD and DE symptoms clustered as expected within networks for each sample. The strongest nodes in the networks included both PTSD and DE features. The strongest bridge symptoms in both studies included overevaluation of shape and weight, negative affect, and avoidance. Networks were invariant across men and women in each sample and largely invariant across samples. Cross-sectional network models of PTSD and DE symptoms largely replicated across national samples of U.S. veterans and between men and women within samples. Cognitive features of both disorders, along with avoidance, may partially underlie comorbidity and represent potential treatment targets.

Efficacy and acceptability of noninvasive brain stimulation for treating posttraumatic stress disorder symptoms: A network meta-analysis of randomized controlled trials.

Despite its high lifetime prevalence rate and the elevated disability caused by posttraumatic stress disorder (PTSD), treatments exhibit modest efficacy. In consideration of the abnormal connectivity between the dorsolateral prefrontal cortex (DLPFC) and amygdala in PTSD, several randomized controlled trials (RCTs) addressing the efficacy of different noninvasive brain stimulation (NIBS) modalities for PTSD management have been undertaken. However, previous RCTs have reported inconsistent results. The current network meta-analysis (NMA) aimed to compare the efficacy and acceptability of various NIBS protocols in PTSD management. We systematically searched ClinicalKey, Cochrane Central Register of Controlled Trials, Embase, ProQuest, PubMed, ScienceDirect, Web of Science, and ClinicalTrials.gov to identify relevant RCTs. The targeted RCTs was those comparing the efficacy of NIBS interventions, such as transcranial direct current stimulation (tDCS), repetitive transcranial magnetic stimulation (rTMS), and transcutaneous cervical vagal nerve stimulation, in patients with PTSD. The NMA was conducted using a frequentist model. The primary outcomes were changes in the overall severity of PTSD and acceptability (to be specific, rates of dropouts for any reason). We identified 14 RCTs that enrolled 686 participants. The NMA demonstrated that among the investigated NIBS types, high-frequency rTMS over bilateral DLPFCs was associated with the greatest reduction in overall PTSD severity. Further, in comparison with the sham controls, excitatory stimulation over the right DLPFC with/without excitatory stimulation over left DLPFC were associated with significant reductions in PTSD-related symptoms, including depression and anxiety symptoms, and overall PTSD severity. This NMA demonstrated that excitatory stimulation over the right DLPFC with or without excitatory stimulation over left DLPFC were associated with significant reductions in PTSD-related symptoms.

“I’m Stronger Now”: A Mixed Methods Exploration of Retrospective Accounts of School Bullying in Young Adults

ABSTRACT Despite the well-known long-term negative effects of school bullying, there is notable lack of research on the positive changes resulting from bullying, including perceptions of personal growth. This mixed methods study was designed to advance current understanding of negative and positive changes of school bullying in former victims. Specifically, it investigated post-traumatic stress disorder symptoms (PTSD), mental resilience and post-traumatic growth (PTG) in former victims. Three-hundred thirty-six young adults who were former victims of school bullying completed questionnaires on retrospective experiences of school bullying, PTSD symptoms, mental resilience, and PTG. For the qualitative part, 10 participants took part in a semi-structured interview. All data were collected online. Qualitative data have been subsequently analyzed through thematic analysis with a phenomenological orientation. Quantitative results indicated that co-existence of multiple forms of bullying as well as victimization in secondary school and stable victimization were associated with higher levels of PTSD [F(5,330) = 6.96, η 2  = .10, p < .05 and F(3,333) = 13.18, η 2 = .07, p < .05, respectively]. They also showed that both PTSD (B = .41, p < .001) and mental resilience (B = .50, p = .001) were predictors of PTG. In qualitative data, benefits (e.g. new life paths and possibilities, appreciation of life) coexisted with negative consequences (e.g. stress, flashbacks, interpersonal difficulties, withdrawal). These findings may significantly contribute toward designing interventions for improving the mental health of former victims of school bullying.

Paradoxical effect of anti-inflammatory drugs on IL-6 mRNA expression in patients with PTSD during treatment.

The pathophysiology of posttraumatic stress disorder (PTSD) is associated with the activation of the innate immune system, including cytokines like interleukin 6 (IL-6). However, the role of IL-6 in the etiology and treatment of PTSD still remains elusive. We conducted a prospective controlled trial to investigate the development of IL-6 during psychosomatic treatment in individuals with PTSD in comparison with individuals without PTSD. We assessed IL-6 mRNA expression before and after 2 months of psychosomatic treatment in individuals with and without PTSD. Severities of PTSD and depressive symptoms were assessed in parallel. Linear mixed regression was applied for statistical analysis, including the factors diagnosis PTSD and pre-post treatment after subgrouping for intake of anti-inflammatory drugs. The development of IL-6 mRNA expression during treatment was affected by the use of anti-inflammatory drugs. In the subgroup without intake of anti-inflammatory drugs, no significant statistical treatment effect in individuals with and without PTSD emerged. In the subgroup of individuals taking anti-inflammatory drugs, a significant interaction effect of the factors pre-post treatment and diagnosis PTSD was observed. Whereas IL-6 mRNA expression in individuals without PTSD decreased according to amelioration of symptoms, IL-6 mRNA expression in individuals with PTSD increased significantly during treatment, in opposite direction to symptom severity. Anti-inflammatory drugs might affect IL-6 mRNA expression in individuals with PTSD in a paradoxical way. This study offers a further piece of evidence that IL-6 could be involved in the pathophysiology of PTSD and PTSD-specific immunologic molecular mechanisms.

Functional significance of posttraumatic growth in U.S. military veterans

BackgroundAlthough many studies indicate that individuals who have experienced a traumatic event can experience posttraumatic growth (PTG), some researchers have questioned the significance of PTG in associations with functioning. The role of PTG in functioning following trauma may be better elucidated by accounting for its joint effects with posttraumatic stress disorder (PTSD) symptoms. MethodsData were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 3847 trauma-exposed U.S. veterans. Participants completed assessments of potentially traumatic events, PTSD symptoms, and PTG, as well as a broad range of sociodemographic, military, trauma, health, personality, and psychosocial characteristics. ResultsPTG was independently and moderately associated with higher mental, cognitive, and psychosocial functioning, but not physical functioning. Results showed a similar pattern of findings when examining relations between subdomains of PTG and these aspects of functioning. Additionally, among veterans who screened positive for PTSD, those who endorsed PTG reported higher levels of mental, cognitive, and/or psychosocial functioning than those who did not endorse PTG. LimitationsFindings may be limited by the use of a cross-sectional design, retrospective self-reports of PTG, and a predominantly older white male veteran sample. ConclusionResults provide support for the functional significance of PTG and highlight the importance of considering PTSD symptoms to better understand the role of PTG in functioning. Clinical interventions to foster PTG may help promote post-trauma functioning.

Alone on the frontline: The first report of PTSD prevalence and risk in de-occupied Ukrainian villages.

The ongoing Russian invasion of Ukraine marks a critical juncture in a series of events posing severe threat to the health of Ukrainian citizens. While recent reports reveal higher rates of PTSD in Ukrainian refugees following Russia's invasion - data for Ukrainians remaining at the warfront is inherently difficult to access. A primarily elderly demographic, Ukrainians in previously Russian-occupied areas near the front (UPROANF) are at particular risk. Data was sourced from screening questionnaires administered between March 2022 and July 2023 by mobile health clinics providing services to UPROANF. Previously occupied villages in Eastern and Southern Ukraine. UPROANF attending clinics completed voluntary self-report surveys reporting demographics, prior health diagnoses, and PTSD symptom severity (n = 450; Meanage = 53.66; 72.0% female). Participants were exposed to Russian occupation of Ukrainian villages. The PTSD Checklist for the DSM-V (PCL-5) with recommended diagnostic threshold (i.e. 31) was utilized to assess PTSD prevalence and symptom severity. ANCOVA was used to examine hypothesized positive associations between (1) HTN and (2) loneliness and PTSD symptoms (cumulative and by symptom cluster). Between 47.8% and 51.33% screened positive for PTSD. Though cumulative PTSD symptoms did not differ based on HTN diagnostic status, those with HTN reported significantly higher PTSD re-experiencing symptoms (b = 1.25, SE = 0.60, p = .046). Loneliness was significantly associated with more severe cumulative PTSD symptoms (b = 1.29, SE = 0.31, p < .001), re-experiencing (b = 0.47, SE = 0.12, p < .001), avoidance (b = .18, SE = 0.08, p = .038), and hypervigilance (b = 0.29, SE = 0.13, p = .036). PTSD prevalence was higher than other war-exposed populations. Findings highlight the urgent mental health burden among UPROANF, emphasizing the need for integrated care models addressing both trauma and physical health. Given the significance of loneliness as a risk factor, findings suggest the potential for group-based, mind-body interventions to holistically address the physical, mental, and social needs of this highly traumatized, underserved population.

Effects of blast exposure on anxiety and symptoms of post-traumatic stress disorder (PTSD) among displaced Ukrainian populations.

Generalized anxiety and symptoms of post-traumatic stress disorder (PTSD) are common among individuals forcibly displaced during war and conflict. Blast exposure may be one important contributor of such symptoms. The aims of this study were to provide data on blast-related experiences of internally displaced persons (IDPs) and refugees following Russia's invasion of Ukraine, and to assess the influence of blast exposure on generalized anxiety, and PTSD flashbacks and nightmares. An online health needs survey was distributed to Ukrainian IDPs and refugees between April and July 2022 using Facebook Ads Manager. Participants reported whether they experienced blast exposure since the beginning of the invasion, and whether they took medication for a mental health condition before the war started. Finally, they completed measures of generalized anxiety (GAD-2), and PTSD flashbacks and nightmares. Analyses included 3253 IDPs and 5073 refugees (N = 8326). Results revealed that 67.6% of total participants- 79.9% of IDPs and 61.7% of refugees-reported blast exposure since Russia's invasion. Further, 69.1% (95% CI: 68.05, 70.15) of total participants met the cut-off for generalized anxiety in which further diagnostic evaluation was warranted. Compared to refugees, IDPs reported higher generalized anxiety and greater frequency of PTSD symptoms, specifically flashbacks and nightmares. Further analyses revealed that the impact of blast exposure on flashback frequency was stronger among IDPs compared to refugees (β = 0.51; t(8322) = 11.88, p < .0001, 95% CI: 0.43, 0.60) and among participants with pre-existing mental health conditions compared to those without (β = 0.18; t(8157) = 2.50, p = .013, 95% CI: 0.04, 0.33). Mental health and psychosocial support must be prioritised within humanitarian relief for both IDPs and refugees and especially among people with underlying mental health conditions.

Posttraumatic stress disorder and spousal relationships in natural disaster victims: a longitudinal study

Background Posttraumatic stress disorder (PTSD) symptoms after natural disaster can have a detrimental effect on marital relationships, which may be through parenting-related factor. Aims The study aimed to examine the mechanism underlying the long-term effects of PTSD symptoms on marital satisfaction via coparenting, and its differences between men and women following the Super Typhoon Lekima. Methods Participants were 465 married victims with children. They reported their PTSD, coparenting, and marital satisfaction at three and fifteen months after the tropical cyclone. Results The results showed that for women, only higher negative cognitive and emotional alterations (NCEA) symptoms were associated with lower marital satisfaction through conflict coparenting. For men, higher intrusion, NCEA, and hyperarousal symptoms were associated with marital satisfaction through different coparenting. To be specific, for men, higher intrusion symptoms were associated with lower marital satisfaction via less reprimand coparenting; higher NCEA symptoms were associated with lower marital satisfaction via less integrity coparenting, and associated with higher marital satisfaction via less conflict coparenting; higher hyperarousal symptoms were associated with lower marital satisfaction via more conflict coparenting. Conclusions These findings suggested that the long-term effect of PTSD symptoms on marital satisfaction via coparenting mainly showed for men.

"He Stole My Meds to Get High:" The Mental Health and Well-Being of Women Abused by Intimate Partners and Their Disability Status.

While population-based research confirms that women with disabilities abused by their intimate partners experience significant mental health issues, few studies compare this in intimate partner violence (IPV)-specific samples of women with or without disabilities and none analyze possible impacts based on disability type. This secondary mixed methods analysis examined 660 Canadian women (50.6% Indigenous, 43.1% White, and 6.1% visible minority) with respect to whether they reported having a disability that impacted their employability or daily living (291 or 44% yes; 369 or 56% said no). In the 291 women with disabilities, about one-third (30.7%) had a physical disability-only, one-quarter had a mental health disability-only, and 44.1% reported both physical and mental health disabilities. Women with mental health and both physical and mental health disabilities reported significantly more Severe Combined IPV on the Composite Abuse Scale, depression (CES-D-10; Center for Epidemiological Studies-Depression), psychological distress (Symptom Checklist Shortform-10; SCL-10; in the clinical range), PTSD symptoms (PTSD Checklist), and lower quality of life (Quality of Life Questionnaire or QoL-9) than women without disabilities. Education about disabilities is needed for IPV advocates and disability practitioners need education about IPV. Developing services specific to survivors of IPV with disabilities is recommended.

Design of a randomized clinical trial of brief couple therapy for PTSD augmented with intranasal oxytocin

BackgroundLeveraging military veterans' intimate relationships during treatment has the potential to concurrently improve posttraumatic stress disorder (PTSD) symptoms and relationship quality. Cognitive-Behavioral Conjoint Therapy (CBCT) and an 8-session Brief Cognitive-Behavioral Conjoint Therapy (bCBCT) are manualized treatments designed to simultaneously improve PTSD and relationship functioning for couples in which one partner has PTSD. Although efficacious in improving PTSD, the effects of CBCT on relationship satisfaction are small, especially among veterans. Intranasal oxytocin, which targets mechanisms of PTSD and relationship quality, may enhance the efficacy of bCBCT. Method/designThe purpose of this 4-year clinical trial is to compare the outcomes of bCBCT augmented with intranasal oxytocin (bCBCT + OT) versus bCBCT plus placebo (bCBCT + PL). We will also explore potential mechanisms of action: self-report communication skills, empathy, and trust. We will recruit 120 dyads (i.e., veteran with PTSD and their intimate partner) from the [masked for peer review]. Veterans will be administered 40 international units of oxytocin (n = 60) or placebo (n = 60) 30 min before each of 8 bCBCT sessions delivered via telehealth. Clinical and functioning outcomes will be assessed at five timepoints (baseline, mid-treatment, post-treatment, and 3- and 6-month follow-up). ConclusionStudy findings will reveal the efficacy of oxytocin-assisted brief couple therapy for PTSD, which could serve as highly scalable option for couples coping with PTSD, as well as provide preliminary evidence of interpersonal mechanisms of change.ClinicalTrials.govIdentifier:NCT06194851

Social Reactions to Disclosures of Multiple-Perpetrator Sexual Assault: Do Number of Offenders Matter?

Sexual assault (SA) victimization is a prevalent issue both in the U.S. and globally. Although SA victimization is usually perpetrated by a single-perpetrator, multiple-perpetrator sexual assaults (MPSAs) also occur. Unfortunately, there is less literature concerning MPSAs, including the well-being of survivors' post-assault. One factor that has been shown to be important in the well-being of SA survivors' post-assault are the social reactions survivors receive from others following disclosure. The current study sought to compare social reactions received by MPSA survivors to the social reactions received by single-perpetrator sexual assault (SPSA) survivors in a community sample of adult female SA survivors (N = 1,863). We examined "turning against" (TA) reactions, a type of negative social reaction in which the supporter expresses more overtly distressing reactions that focus blame on the victim. We also examined unsupportive acknowledgment reactions (UA) the second type of negative reaction in which survivors receive acknowledgment that the assault occurred but are not supported. Additionally, we examined differences in positive reactions that survivors received from their support systems. One-way Analysis of Variance showed statistically significant differences in social reactions to disclosure according to number of offenders in the SA, with MPSA survivors receiving more TA and UA negative reactions than SPSA survivors. There were no differences in positive reactions by number of offenders. Multiple regression analyses also revealed that several demographics, assault characteristics, and post-assault factors (total Post-Traumatic Stress Disorder (PTSD) symptoms, coping, attributions of self-blame) were related to the social reactions received by MPSA survivors post-assault. Implications and recommendations for support providers are discussed.

The burden of anxiety, depression, and stress, along with the prevalence of symptoms of PTSD, and perceptions of the drivers of psychological harms, as perceived by doctors and nurses working in ICUs in Nepal during the COVID-19 pandemic; a mixed method evaluation.

The COVID-19 pandemic resulted in significant physical and psychological impacts for survivors, and for the healthcare professionals caring for patients. Nurses and doctors in critical care faced longer working hours, increased burden of patients, and limited resources, all in the context of personal social isolation and uncertainties regarding cross-infection. We evaluated the burden of anxiety, depression, stress, post-traumatic stress disorder (PTSD), and alcohol dependence among doctors and nurses working in intensive care units (ICUs) in Nepal and explored the individual and social drivers for these impacts. We conducted a mixed-methods study in Nepal, using an online survey to assess psychological well-being and semi-structured interviews to explore perceptions as to the drivers of anxiety, stress, and depression. Participants were recruited from existing national critical care professional organisations in Nepal and using a snowball technique. The online survey comprised of validated assessment tools for anxiety, depression, stress, PTSD, and alcohol dependence; all tools were analysed using published guidelines. Interviews were analysed using rapid appraisal techniques, and themes regarding the drivers for psychological distress were explored. 134 respondents (113 nurses, 21 doctors) completed the online survey. Twenty-eight (21%) participants experienced moderate to severe symptoms of depression; 67 (50%) experienced moderate or severe symptoms of anxiety; 114 (85%) had scores indicative of moderate to high levels of stress; 46 out of 100 reported symptoms of PTSD. Compared to doctors, nurses experienced more severe symptoms of depression, anxiety, and PTSD, whereas doctors experienced higher levels of stress than nurses. Most (95%) participants had scores indicative of low risk of alcohol dependence. Twenty participants were followed up in interviews. Social stigmatism, physical and emotional safety, enforced role change and the absence of organisational support were perceived drivers for poor psychological well-being. Nurses and doctors working in ICU during the COVID-19 pandemic sustained psychological impacts, manifesting as stress, anxiety, and for some, symptoms of PTSD. Nurses were more vulnerable. Individual characteristics and professional inequalities in healthcare may be potential modifiable factors for policy makers seeking to mitigate risks for healthcare providers.

Effect of PTSD treatment on cardiovascular reactivity during trauma memory recall and correspondence with symptom improvement

ABSTRACT Background: Prior research has shown PTSD treatment leads to reductions in cardiovascular reactivity during trauma recall, but the extent to which such reductions are associated with changes in PTSD symptoms is less clear. Moreover, such relationships have not been investigated in a cognitively focused PTSD treatment. Objective: To examine changes in cardiovascular reactivity to the trauma memory in patients receiving cognitive processing therapy (CPT), CPT with a written trauma account, and a written account only condition. We also examined the association of such changes with symptom improvement. Method: 118 women with PTSD secondary to interpersonal violence completed pre- and post-treatment assessments of PTSD symptoms and cardiovascular reactivity during a script-driven imagery task. Results: Results indicated a significant but modest reduction in cardiovascular reactivity in CPT conditions. Changes in cardiovascular reactivity and reexperiencing symptoms were significantly associated among the whole sample. Among individuals with the greatest reactivity to the trauma memory at pretreatment, associations were also seen with changes in total PTSD, numbing, and trauma-related guilt. Conclusions: Results indicate that previous findings on the effect of PTSD treatment on cardiovascular reactivity during trauma recall extend to cognitively oriented treatment. Baseline cardiovascular reactivity may influence the extent to which reductions in PTSD symptoms and reactivity during trauma recall are related.

Post-Traumatic Stress Disorder in Brazilian Pregnant Women at the Beginning of the Coronavirus Disease Pandemic

Objective: Analyze the presence of PTSD symptoms and their risk among the pregnant women during the COVID-19 pandemic. Methods: This is a cross-sectional study of pregnant women that received receiving prenatal care at two university hospitals in São Paulo, Brazil, during the COVID-19 pandemic, from April to June 2020. The sociodemographic and health data of the participants and their exposure to individuals suspected or confirmed to have COVID-19 were evaluated. The Impact of Event Scale-Revised and the State-Trait Anxiety Inventory were used to assess PTSD and anxiety symptoms, respectively. Results: A total of 149 pregnant women were included in this study. The risk of PTSD among the participants was 55.1%. The independent risk factors for PTSD were state anxiety (ORadj = 2.6), trait anxiety (ORadj = 10.7), changes in routine due to the pandemic (ORadj = 4.7) and contact with a confirmed case of COVID-19 person (ORadj = 7.1). Conclusions: The COVID-19 pandemic had a significant negative impact on the mental health of pregnant women, more than half of the participants of the present study showed a risk of PTSD, exacerbated by anxiety symptoms and exposure to individuals with a confirmed case of COVID-19.

The effect of a visuospatial interference intervention on posttraumatic intrusions: a cross-over randomized controlled trial

ABSTRACT Background: Intrusive memories form a core symptom of Posttraumatic Stress Disorder (PTSD). Based on concepts of visuospatial interference and memory-updating accounts, technological innovations aim to attenuate such intrusions using visuospatial interventions. Objective: This study aims to test the effect of a visuospatial Tetris-based intervention versus a verbal condition (Wiki) and a never-targeted control (no intervention) on intrusion frequency. Method: A randomized crossover trial was conducted including N = 38 PTSD patients who had at least 3 distinct intrusive memories of trauma. After both 2 weeks (intervention 1) and 4 weeks (intervention 2), one of the three memories was randomly selected and either the visuospatial intervention (memory reminder of a traumatic memory + Tetris) or verbal condition (reading a Wikipedia article + answering questions) was performed on their first memory in randomized order. In the week 4 session, the patient conducted the other intervention condition on their second memory (crossover). The third memory was never targeted (no intervention). Daily occurrence of intrusions over 8 weeks was collected using a diary and analysed using mixed Poisson regression models. Results: Overall, there was no significant reduction in intrusion frequency from either intervention compared to each other, and to no intervention control (relative risk Tetris/Wiki: 0.947; p = .31; relative risk no intervention/Tetris: 1.060; p = .15; relative risk no intervention/Wiki: 1.004; p = .92). Conclusions: There was no effect of either intervention on intrusions when administered in a crossover design where participants received both interventions. Design shortcomings and consequences for future studies are discussed.

Association of Daily Activities With Maternal-Child Bonding, Parenting Self-Efficacy, Social Support, and Parenting Behaviors Among Survivors Living in an Intimate Partner Violence Shelter: A Daily Diary Study.

Following a traumatic event such as intimate partner violence (IPV), survivors often experience stress related to the violence. These high levels of stress related to IPV can be associated with the daily activities of survivors and their relationships with their children, such as maternal-child bonding. The purpose of the current study is to explore the relationship between daily activities, daily stress levels, parenting self-efficacy and behaviors, and maternal-child bonding among survivors living in an IPV shelter using an ecological momentary assessment (EMA) methodology. Twenty-five mothers living in an IPV shelter in two states in the Southern United States completed a baseline survey and completed electronic daily diaries for 14 days. Higher daily stress was associated with the number of times the mothers met with the case manager. Higher daily stress was also related to lower parenting self-efficacy. The number of case management appointments and legal appointments were positively correlated with a higher bonding score. More social support was associated with more positive parenting. IPV and post-traumatic stress disorder symptoms were not significantly associated with maternal-child bonding, parenting behaviors, or parenting self-efficacy. Findings suggest that screening for maternal support may be particularly important for positive bonding and positive parenting. Findings also lend preliminary insight into practical places where service providers could act to protect the bonding process or mitigate risks to impede it. Future research should include objective data about the mother's emotions and her interactive behavior with her child. There is also a need to consider how federal programs fund and incentivize service providers to focus on mother-child dyads and how they can tailor services that promote bonding.

Neighborhood Safety and Perinatal Mental Health

Neighborhood safety (NS) has important implications for mental health, yet research is needed to clarify how different constructs that measure NS associate with mental health problems. Research is particularly underdeveloped on NS among low-income, postpartum individuals, who may experience greater vulnerability. This study examined two measures of NS, self-reported and coder-rated, and their associations with prenatal and postnatal depression and PTSD symptoms, and lifetime adversity. Participants were 121 perinatal individuals living in a major metro area. Both types of NS were significantly intercorrelated. Neither prenatal nor postnatal depression symptoms predicted self-reported or coder-rated NS. However, higher lifetime adversity and higher postnatal PTSD symptoms predicted lower self-reported postnatal NS (but not coder-rated NS). After controlling for prenatal PTSD symptoms, lower self-reported NS also predicted higher postnatal PTSD symptoms. Findings underscore the importance of focusing on individuals’ lived experiences in their neighborhoods to understand links between perceptions of NS and PTSD symptoms.
