Total Posttraumatic Stress Disorder Symptoms Research Articles

A Combined Kundalini Yoga and Cognitive Behavioral Therapy Program for Posttraumatic Stress Disorder: A Pilot Study.

Cognitive behavioral therapy (CBT) is one of the standard conventional treatments for posttraumatic stress disorder (PTSD). However, recent studies have reported the benefits of yoga for reducing PTSD symptoms including a Kundalini Yoga (KY) intervention. The purpose of this study was to test the efficacy of a novel combined 8-week CBT and KY program for treating PTSD symptoms and improving sleep quality in a single group trial of 26 adults with PTSD. PTSD symptoms (PTSD checklist-5) and sleep quality (Pittsburgh Sleep Quality Index) were assessed at baseline, post intervention, and at 2-month follow-up. Both CBT and yoga homework compliance were also measured. Total PTSD symptom scores as well as the cluster symptoms (intrusion, avoidance, arousal/reactivity, and negative alterations in cognitions and mood) were significantly improved following the program, all p < .01. The improvements in total PTSD scores, intrusion, avoidance, arousal/reactivity were maintained at follow-up, with all values still less (p < .01) than baseline. The negative alterations in cognitions and mood symptom cluster continued to improve further at follow-up compared to post-intervention values (p < .05). Total sleep score (p < .05) and the subscales of sleep disturbance (p < .01), daytime dysfunction (p < .05), and sleep quality (p < .01) were significantly improved after the program and these improvements were maintained at follow-up compared to baseline. Sleep medication use was decreased (p < .05) and sleep latency was improved (p < .01) at follow-up only compared to baseline. There was a significant positive correlation (p < .05) between the completion of the yoga home practice and post change in total sleep scores. These results show that a combined KY and CBT intervention resulted in decreased PTSD symptoms and improved sleep quality and suggest this program may constitute an additional treatment option for PTSD.

Abstract 14: Post-Traumatic Stress Disorder Symptoms and Physical Activity Behavior After Hospitalization for Suspected Acute Coronary Syndromes

Background: An acute coronary syndrome (ACS) related event can induce post-traumatic stress disorder (PTSD), and post-ACS PTSD is associated with a greater risk for secondary clinical outcomes among ACS survivors. While moderate-vigorous physical activity (MVPA) has been shown to reduce the risk of adverse outcomes after ACS, its impact on PTSD symptoms remains largely unknown. There is a notable absence of empirical evidence, especially from large-scale observational cohort studies with device-based measures of physical activity, on this topic. Aim: To investigate the relationship between physical activity behaviors over the first month post-discharge with PTSD symptoms at one month among patients with suspected ACS. Methods: Patients (n = 434, 48.6% female, 62.6±12.4yrs) evaluated for ACS in the emergency department were fitted with a GENEActiv wrist accelerometer in-hospital and wore the device on their non-dominant wrist for 30 days post-discharge to measure MVPA. Presence and severity of PTSD symptoms were assessed at 1-month follow-up using the PCL-5. Multilevel structural equation modeling was used to simultaneously 1) fit a linear growth curve (GC) model to patients’ 30-day trajectories of MVPA and 2) predict total PTSD symptoms from a) mean daily MVPA, b) average daily change in MVPA (GC slope), and c) covariates (age, biological sex, education, and Charlson Comorbidity Index). Results: Patients engaged in an average of 20.8 (95% CI: 18.4, 23.3, p &lt; 0.001) minutes of MVPA per day. MVPA levels increased at an average rate of 0.11 mins/day (95% CI: 0.05, 0.16, p &lt; 0.001) over the 30 days post-discharge. There was substantial between-patient variability in both average MVPA minutes (SD = 26.0) and daily rate of change in MVPA minutes (SD = 0.38). The daily rate of change in MVPA was significantly associated with 1-month PTSD symptoms (β per 0.5 mins/day difference in daily rate of change in MVPA minutes = -4.5 points on the PCL-5; 95% CI: -6.5, -2.5, p &lt; 0.001), controlling for the above-mentioned covariates. The association between average MVPA minutes and PCL-5 score was small and not statistically significant (β = 0.02; 95% CI: -0.04, 0.07, p = 0.60). Conclusion: PTSD symptoms appear to be mitigated in patients whose MVPA minutes increased over the 30 days post-discharge, whereas no evident association was observed between PTSD symptoms and average daily MVPA minutes. These findings suggest that progressively increasing MVPA by as little as .5 mins/day (i.e., ~1 SD above the mean rate of increase) within the immediate first month post-discharge, as opposed to maintaining a consistent daily average of MVPA, may impede the development of PTSD symptoms in ACS survivors.

Heart rate reactivity during trauma recall as a predictor of treatment outcome in cognitive processing therapy for PTSD

Emotional engagement when recollecting a trauma memory is considered a key element of effective trauma-focused therapy. Research has shown that reduced physiological reactivity during trauma recall is associated with worse treatment outcomes for posttraumatic stress disorder (PTSD), but this has yet to be examined in a cognitively oriented treatment. This study examined whether pretreatment heart rate (HR) reactivity during trauma recall predicts PTSD symptom improvement and treatment dropout during Cognitive Processing Therapy (CPT) for PTSD. Participants were 142 women with PTSD secondary to interpersonal violence enrolled in one of two clinicals trials. HR reactivity reflected the mean increase in HR after listening to two 30-s scripts of the trauma memory prior to treatment. Linear mixed-effects models showed the effect of HR reactivity on change in total PTSD symptoms was not significant, but lower HR reactivity predicted less improvement in reexperiencing and avoidance and was associated with increased dropout. Findings suggest pretreatment physiological reactivity to the trauma memory may be a prognostic indicator of some elements of treatment response in CPT. Results tentatively support the importance of emotional activation during trauma recall in cognitive treatment of PTSD, though more research is needed to clarify how low HR reactivity impacts treatment.

Distress overtolerance among firefighters: Associations with posttraumatic stress.

Firefighters experience heightened rates of posttraumatic stress disorder (PTSD) symptoms compared to the general population. Nascent literature has identified distress overtolerance (DO; i.e., the tendency to persist through extremely high levels of distress despite harmful consequences) as a construct of potential relevance to PTSD symptomatology, though empirical research is lacking. The present study examined incremental associations between DO subscales (Capacity for Harm: persevering through distress despite its effect on 1's wellbeing; Fear of Negative Evaluation: persisting through distress due to a fear of being negatively evaluated by others should they quit) and PTSD symptom severity and symptom cluster severity (i.e., intrusion, avoidance, negative alterations in cognitions and mood [NACM], arousal and reactivity) among firefighters. Participants included 282 trauma-exposed firefighters (91.8% male, Mage = 40.4, SD = 9.6). Covariates included years in the fire service, trauma load (i.e., number of trauma exposure types), and negative affect. Results indicated that Capacity for Harm was a significant incremental correlate of total PTSD symptom severity (ΔR² = .045, p = .004), NACM symptoms (ΔR² = .061, p < .001), and arousal/reactivity symptoms (ΔR² = .047, p = .005). Fear of Negative Evaluation was not significantly related to any criterion variables. Further work examining DO-PTSD relations is necessary to inform intervention and policy for the fire service.

Association between perimenopausal age and greater posttraumatic stress disorder and depression symptoms in trauma-exposed women.

This study aimed to determine the relationship between stages of the menopause transition (premenopausal, perimenopausal, and postmenopausal) on symptoms of posttraumatic stress disorder (PTSD) and depression in trauma-exposed women. A cross-sectional study conducted between 2005 and 2017 recruited and enrolled an urban community sample (n = 6,093) from nonpsychiatric medical clinic waiting rooms of Grady Memorial Hospital, a public safety net hospital in Atlanta, Georgia. Participants were female, 18 to 65 years old, and predominantly Black/African American. Of the 6,093 participants, 93.8% were Black/African American, 2.5% were White, and 3.8% were of all other races (Hispanic/Latino, Asian, multiracial). Participants younger than 40 years were categorized as premenopausal (n = 3,166), between 40 and 55 years of age were categorized as perimenopausal (n = 2,127), and older than 55 years were categorized as postmenopausal (n = 790). Menopause status was associated with total PTSD symptom severity ( F2,5416 = 9.61, P < 0.001), symptom severity within all three PTSD symptom clusters (avoidance/numbing symptoms: F2,5416 = 7.10, P < 0.001; intrusive symptoms: F2,5416 = 7.04, P < 0.001; hyperarousal symptoms: F2,5409 = 8.31, P < 0.001), and depression symptom severity ( F2,5148 = 11.4, P < 0.001). Compared with both premenopausal and postmenopausal women, perimenopausal women reported significantly worse total PTSD symptoms, symptoms in the hyperarousal cluster, and depressive symptoms. The current cross-sectional data show that symptoms of PTSD and depression in women are associated with reproductive age, such that perimenopausal women show higher symptom severity than premenopausal and postmenopausal women. Future longitudinal studies can reveal how changes in hormones over the course of the menopause transition impact the symptoms, neurobiology, and psychophysiology of PTSD.

Skin Conductance Reactivity as a Predictor of Stroke-Induced Posttraumatic Stress Disorder Symptoms: A Dimensional Approach

Background. Posttraumatic stress disorder (PTSD) symptoms can develop following acute, life-threatening medical events. This study explores a potential biomarker of PTSD risk that is novel to a medical trauma population: a noninvasive, mobile skin conductance (SC) measurement. Methods. Participants ( n = 64 ) were enrolled inhospital following a stroke or transient ischemic attack (TIA). Mobile measurement of SC reactivity to recalling the stroke/TIA traumatic event was conducted at hospital bedside in the days following the stroke/TIA. PTSD symptoms that developed in response to the stroke/TIA were measured at 1-month follow-up. We tested the association between SC reactivity and total 1-month PTSD symptoms, as well as PTSD symptom dimensions of fear and dysphoria. Results. In unadjusted analyses, there were significant positive associations between inhospital SC reactivity to recalling the stroke/TIA traumatic event and higher-order fear-related symptoms ( r = .30 , p = .016 ), as well as lower-order fear-related symptoms of anxious arousal ( r = .27 , p = .035 ) and avoidance ( r = .25 , p = .043 ) at 1 month. Associations between SC reactivity and the fear, anxious arousal, and avoidance symptom dimensions remained significant in multivariable regression models that adjusted for relevant covariates including age, gender, stroke severity, medical comorbidity, and psychosocial factors. Although there was a positive association observed between SC reactivity to recalling the stroke/TIA event and total PTSD symptom severity at 1-month follow-up, it did not reach the level of statistical significance ( r = .23 , p = .070 ). Further, no significant association was detected for dysphoria-related symptoms ( r = .11 , p = .393 ). Conclusions. This is the first study to test the prospective association of SC reactivity with PTSD symptom development following a medical trauma. The findings indicate that mobile measures of SC reactivity may be useful for inhospital identification of individuals at risk for fear-related PTSD symptom development following a medical event and highlight the potential mechanisms involved in the development of these symptoms following a medical event.

Do changes in dysfunctional posttraumatic cognitions differentially predict PTSD symptom clusters?

In recent years, it has been suggested that the modification of dysfunctional posttraumatic cognitions plays a central role as a mechanism of change in cognitive behavioral therapy (CBT) for posttraumatic stress disorder (PTSD). Indeed, several studies have shown that changes in dysfunctional posttraumatic cognitions precede and predict symptom change. However, these studies have investigated the influence on overall symptom severity-despite the well-known multidimensionality of PTSD. The present study therefore aimed to explore differential associations between change in dysfunctional conditions and change in PTSD symptom clusters. As part of a naturalistic effectiveness study evaluating trauma-focused cognitive behavioral therapy for PTSD in routine clinical care, 61 patients with PTSD filled out measures of dysfunctional posttraumatic cognitions and PTSD symptom severity every five sessions during the course of treatment. Lagged associations between dysfunctional cognitions and symptom severity at the following timepoint were examined using linear mixed models. Over the course of therapy, both dysfunctional cognitions and PTSD symptoms decreased. Posttraumatic cognitions predicted subsequent total PTSD symptom severity, although this effect was at least partly explained by the time factor. Moreover, dysfunctional cognitions predicted three out of four symptom clusters as expected. However, these effects were no longer statistically significant when the general effect for time was controlled for. The present study provides preliminary evidence that dysfunctional posttraumatic cognitions predict PTSD symptom clusters differentially. However, different findings when employing a traditional versus a more rigorous statistical approach make interpretation of findings difficult.

Altered functional connectivity between cortical networks associated with inhibitory control in trauma-exposed females

Post-traumatic stress disorder (PTSD) is associated with impaired inhibitory control and alterations in large-scale brain network connectivity. However, few studies to date have examined the construct of inhibitory control as it relates to resting-state functional connectivity (rsFC) in a population with PTSD or trauma-exposure. The present study investigated the relationship between impaired inhibitory control and rsFC within the default mode network (DMN), central executive network (CEN), and salience network (SN) in a sample of females exposed to interpersonal trauma with and without PTSD (n = 67). Participants completed a classic Color-Word Stroop task as a measure of inhibitory control and two resting-state fMRI scans. We conducted voxelwise rsFC analyses with seed regions in the DMN, CEN, and SN and voxelwise linear regression analyses to examine the relationship between inhibitory control and rsFC of these networks across the sample. Better Stroop performance was negatively associated with total self-reported PTSD symptoms. An analysis of PTSD symptom clusters indicated that better Stroop performance was also associated with re-experiencing and hyperarousal symptoms, but not avoidance PTSD symptoms. Decreased coupling between the CEN and the DMN was associated with better inhibitory control in this sample of trauma-exposed females. These findings lend support to the hypothesis that efficient switching between these networks may contribute to better performance on cognitive and attentional tasks in trauma-exposed individuals.

Concurrent and proximal associations among PTSD symptoms, prescription opioid use, and co-use of other substances: Results from a daily monitoring study.

Posttraumatic stress disorder (PTSD) and nonmedical prescription opioid use (NMPOU) are linked. Much of the research documenting this association uses cross-sectional or longitudinal designs that describe patterns of use over extended intervals. The present study used a daily monitoring design to examine how daily fluctuations in PTSD symptoms predicted patterns of prescription opioid use (both medical and nonmedical) and co-use of other substances. This approach has distinct advantages for understanding proximal temporal relations between PTSD symptom variation and substance use patterns. Forty adults with clinical or subclinical PTSD and past-month NMPOU completed daily measures of PTSD symptoms, physical pain, prescription opioid use, and other substance use for 28 days using a smartphone application. Same day co-use of prescription opioids and at least one other substance was common. Higher-than-typical PTSD symptoms on a given day (within-person) was associated with an increased likelihood of reporting NMPOU (overall and with co-use of one or more additional substances) on the same day. This association was specific to PTSD alterations in arousal and reactivity symptoms (Criteria E). Neither total PTSD symptoms nor individual PTSD symptom clusters prospectively predicted next-day prescription opioid use (overall or with co-use). Use of prescription opioids also did not predict next-day PTSD symptom severity. This is the first study to demonstrate positive associations between day-to-day fluctuations in PTSD symptoms and NMPOU. Results from the current study also highlight the importance of examining polysubstance use patterns among individuals with PTSD who use prescription opioids.

Trauma, post-traumatic stress disorder and violence in the prison population: prospective cohort study of sentenced male prisoners in the UK.

Violence is a common problem in prisons. Post-traumatic stress disorder (PTSD), a prevalent disorder in prison populations, has been identified as a risk factor for violent behaviour in community and military populations. Although cross-sectional associations between PTSD and prison violence have been documented, prospective cohort studies are required. To investigate whether PTSD is an independent risk factor for prison violence, and examine the potential role of PTSD symptoms and other trauma sequelae on the pathway from trauma exposure to violent behaviour in prison. A prospective cohort study was conducted in a large, medium security prison in London, UK. A random sample of sentenced prisoners arriving into custody (N = 223) took part in a clinical research interview, which assessed trauma histories, mental disorders including PTSD, and other potential sequelae of trauma (anger, emotion dysregulation). Incidents of violent behaviour were measured with prison records covering the 3 months after reception into custody. Stepped binary logistic regression and a series of binary mediation models were performed. Prisoners who met current (past month) criteria for PTSD were more likely to engage in violent behaviour during the first 3 months of imprisonment, after adjusting for other independent risk factors. The relationship between lifetime exposure to interpersonal trauma and violent behaviour in custody was mediated by total PTSD symptom severity. Hyperarousal and negatively valenced cognitive and emotional appraisal symptoms were particularly implicated in this pathway. The identification and treatment of PTSD has the potential to reduce violence in prison populations.

Medical cannabis for treatment-resistant combat PTSD.

Targeting the endocannabinoid system may have a role in the treatment of post-traumatic stress disorder (PTSD). However, few studies have examined the effectiveness of cannabis on symptoms of PTSD, and more research is needed to ascertain cannabis' effectiveness. In this retrospective naturalistic study, we followed 14 relatively mature (32-68 years of age), treatment-resistant, chronic combat post-traumatic patients who remained severely symptomatic despite treatment with many lines of conventional treatment prior to receiving medicinal cannabis. Our findings show that total sleep score, subjective sleep quality, and sleep duration significantly improved (p < 0.01). Total PTSD symptom score and its subdomains (intrusiveness, avoidance, and alertness) showed improvement (p < 0.05). However, there was no improvement in the frequency of nightmares (p = 0.27). The mean follow-up time was 1.1 ± 0.8 years (range of 0.5 to 3 years).

Obsessive-compulsive symptoms and daily experiences of posttraumatic stress and mental contamination following sexual trauma

Although cross-sectional research highlights similarities between symptoms of obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) among individuals exposed to sexual trauma, little is known about how these disorders relate over time. The goal of the present study was to examine whether 1) OCD symptoms prospectively predicted daily symptoms of PTSD, and 2) OCD and PTSD symptoms prospectively predicted daily experiences of sexual trauma-related mental contamination (i.e., dirtiness in the absence of a physical pollutant). Forty-one women with a sexual trauma history completed baseline measures of OCD and PTSD, as well as twice-daily assessments of PTSD symptoms and mental contamination over a two-week period. Total OCD symptoms and the unacceptable thoughts dimension significantly predicted daily PTSD symptoms after accounting for other OCD dimensions. Only total OCD symptoms significantly predicted daily mental contamination when examined together with total PTSD symptoms. No individual PTSD or OCD clusters/dimensions significantly predicted daily mental contamination when examined simultaneously. Findings from this study highlight the nuanced associations among OCD symptoms, PTSD symptoms, and experiences of mental contamination. Future research is needed to further understand the development of PTSD, OCD, and mental contamination over time to inform targets for intervention.

Posttraumatic stress disorder and coping strategies in the postpartum period: A symptomics approach

Posttraumatic stress disorder (PTSD) has been increasingly recognized as a potential mental health concern for new mothers. Elevated PTSD symptoms have been associated with maladaptive coping strategies in the postpartum period, a time when women face many challenges, demands, and stressors. However, PTSD symptoms manifest in heterogeneous ways, and focusing only on total symptom scores may obscure more nuanced associations with particular coping styles. In a large, ethnically diverse sample of postpartum women from across the United States (N = 1,315), first we examined associations between total PTSD symptom severity with three distinct coping styles: active-emotional, avoidant-emotional, and problem-focused. In models adjusting for race and educational attainment, total PTSD symptom severity was significantly positively associated with tendencies to use active- and avoidant-emotional, but not problem-focused, coping. We then adopted a novel “symptomics” approach, employing relative importance analyses to examine associations between individual PTSD symptoms with the coping styles. These analyses identified PTSD symptoms that were most strongly associated with each coping style. Notably, whereas several symptoms explained variance in avoidant-emotional coping, only a few symptoms contributed most to active-emotional and problem-focused coping. Moreover, non-specific symptoms of PTSD that are shared with other psychopathology (e.g., difficulty concentrating, loss of interest) explained significant proportions of variance across all coping styles. Collectively, results suggest that a symptomics approach may provide more nuanced insight into how PTSD symptoms are linked to various coping styles in postpartum women, which can help inform potential screening and intervention targets for at-risk women during this period.

A survey of Post-Traumatic Stress Disorder, Anxiety and Depression among Flood Affected Populations in Kerala, India.

BackgroundGlobally, post traumatic stress disorder (PTSD) is one of the most common psychiatric illnesses following a disaster. We aimed to evaluate the relationship between the socio-economic and flood exposure factors with PTSD, depression and anxiety among the flood-affected populations in Kerala, India.MethodsA cross-sectional household survey was conducted from November 2019 to January 2020 in Kozhikode district of Kerala, India. Adults (≥ 18 years), who were permanent residents and had been directly exposed to the flood, were invited to take part in the study. Individuals with a history of mental health issues and those who had other stressful situations in the past were excluded. The survey questionnaire was based on three screening tools: (1) PTSD Checklist for DSM-5 (PCL-5); (2) patient health questionnaire (PHQ-9); and (3) generalized anxiety disorder (GAD-7). Data included sociodemographic factors and flood exposure variables. The primary outcome variable was psychiatric morbidity (PTSD, anxiety and depression).ResultsA total of 276 respondents (150 males/126 females) participated in the study. A significant correlation was observed between total score on PCL-5 and GAD-7 (r=0.339, p=0.001) and PHQ-9 (r=0.262, p=0.001). Females had significantly higher total PTSD symptom severity scores (8.24±5.88 vs. 6.07±5.22; p=0.001), severity of symptoms of intrusion (4.66±3.60 vs. 3.69±3.20; p=0.04), increased level of anxiety (2.54±1.94 vs. 1.79±1.53; p=0.001) and depression (3.02±2.26 vs. 2.04±1.67; p=0.001) compared to males. However, the gender difference for PTSD symptoms disappeared when controlling for age.ConclusionThe findings of this survey revealed that the vast majority of respondents (92 percent females and 87 percent males) still had subclinical psychiatric symptoms one year after the flood. Therefore, tailored psychological interventions are warranted to counter the long-lasting impact of flooding on the mental health of individuals.

Association Between Changes in Post-hospital Cardiac Symptoms and Changes in Acute Coronary Syndrome-Induced Symptoms of Post-traumatic Stress.

BackgroundAfter acute coronary syndrome (ACS), one in eight patients develops clinically significant symptoms of Post-traumatic stress disorder (PTSD). We hypothesized that changes in cardiac symptoms from 3 to 12 months after ACS are associated with changes in ACS-induced PTSD symptoms.MethodsAt 3 (n = 154) and/or 12 months (n = 106) post-ACS, patients (n = 156, mean age 59 years, 85% men) completed a clinical interview assessing chest tightness/pain (at rest and/or during exertion), heartbeat symptoms (heart palpitations, racing of heart, heart stumbling or skipping a beat) and PTSD symptoms during the prior 4 weeks. Random mixed regression models examined the association between the onset (or remission) from 3 to 12 months in cardiac symptoms with changes in PTSD symptoms, adjusting for a range of potential predictors of ACS-induced PTSD symptoms.ResultsThe onset of chest tightness/pain [estimate = 0.588, 95% confidence interval: 0.275, 0.090; p < 0.001] and of heartbeat symptoms [0.548 (0.165, 0.931); p = 0.005] from 3 to 12 months was independently associated with an increase in total PTSD symptoms. There were also independent associations between the onset of chest tightness/pain and heartbeat symptoms with an increase in PTSD symptom clusters. Specifically, the onset of chest tightness/pain showed associations with an increase in re-experiencing [0.450 (0.167, 0.733); p = 0.027] and avoidance/numbing [0.287 (0.001, 0.574); p = 0.049]. The onset of heartbeat symptoms showed associations with an increase in re-experiencing [0.392 (0.045, 0.739); p = 0.002], avoidance/numbing [0.513 (0.161, 0.864); p = 0.004] and hyperarousal [0.355 (0.051, 0.659); p = 0.022]. An increase in the total number of cardiac symptoms (score range 0–6) was also associated with an increase in total PTSD symptoms [0.343 (0.202, 0.484); p < 0.001]. Psychotherapy in the post-hospital period moderated the association between the change in heartbeat symptoms and the change in total PTSD symptoms [−0.813 (−1.553, −0.074); p = 0.031 for interaction]; the association between the onset of heart beat symptoms and an increase in total PTSD symptoms was weaker in patients who attended psychotherapy [0.437 (−0.178, 1.052); p = 0.16] than in those who did not [0.825 (0.341, 1.309); p < 0.001].ConclusionChanges in cardiac symptoms between 3 and 12 months after hospitalization are associated with changes in ACS-induced PTSD symptoms.

Locating event centrality in associations of emotion regulation with posttraumatic stress disorder symptoms and posttraumatic growth in emerging adults

Previous research suggests that cognitive reappraisal (CR) and expressive suppression (ES) strategies of emotion regulation (ER) are associated with posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). How the patterns of these associations may vary in the context of event centrality (EC) however requires investigation to help delineate groups for whom the impact of event centrality may be more salient. We examined whether EC would moderate the associations of CR and ES with PTSD symptoms clusters and PTG domains among 388 emerging adults (18-30 year-olds) of Tiv ethnic group who were survivors of armed attack by Fulani herdsmen and were temporarily sheltered in two internally displaced persons’ (IDPs’) camps in North-central Nigeria. They completed self-report measures of the variables. Results indicated that EC strengthened the negative associations of CR and the positive associations of ES with avoidance, hyper-arousal and total PTSD symptoms, but not intrusion symptoms. For the PTG domains, EC only strengthened the positive association between CR and personal strength and weakened the association of ES with greater appreciation of life. These findings suggest that primary intervention programs that incorporate training of armed attack survivors in cognitive reappraisal strategy centered on the traumatic event could be effective in controlling PTSD but be less critical in engendering PTG. They also show that the psychological processes that underlie PTSD and PTG are related but involve nuances even within PTSD, and do not seamlessly set into the Janoff-Bulman's “strength through suffering” model of PTG. More research is required to test the model.

Formal mindfulness practice predicts reductions in PTSD symptom severity following a mindfulness-based intervention for women with co-occurring PTSD and substance use disorder

BackgroundWomen with co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD) experience systemic barriers that place them in danger of poorer treatment outcomes. Some mindfulness-based interventions (MBIs) have demonstrated efficacy in reducing PTSD and SUD symptoms. Mindfulness practice is a core component of MBIs, thought to elicit and maintain positive behavioral change; however, no research to our knowledge has assessed the role of mindfulness practice on sustained treatment gains among women with co-occurring PTSD-SUD. Such research is necessary to better inform MBIs for dually diagnosed women.MethodsThis secondary analysis assessed whether post-intervention formal and informal mindfulness practice predicted reductions in PTSD symptoms and substance craving 6 months following an 8-session mindfulness-based relapse prevention intervention for women diagnosed with co-occurring PTSD-SUD (N = 23). Data were derived from a pilot randomized controlled trial evaluating the feasibility and preliminary efficacy of a trauma-integrated mindfulness-based relapse prevention program for women with co-occurring PTSD-SUD.ResultsGreater duration of formal mindfulness practice (i.e., minutes per practice) predicted reduced total PTSD symptoms (upbeta = − .670, p < .00), trauma-related avoidance (upbeta = − .564, p = .01), arousal and reactivity (upbeta = − .530, p = .02), and negative cognitions and mood (upbeta = − .780, p < .01) six months following treatment. Informal practice did not predict any outcomes.ConclusionsThis research highlights the potential role of formal mindfulness practice in sustaining reductions in PTSD symptoms over time among women with co-occurring PTSD-SUD. Further study of strategies to promote ongoing formal mindfulness practice in this population following a MBI are warranted.Trial registration The parent trial was registered with ClinicalTrials.gov (Identifier: NCT03505749).

Prospective association between pro-inflammatory state on admission and posttraumatic stress following acute coronary syndrome

ObjectiveThe traumatic experience of acute coronary syndrome (ACS) may induce symptoms of posttraumatic stress disorder (PTSD). We examined whether the ACS-triggered acute inflammatory response predicts the development of PTSD symptoms. MethodStudy participants were 70 patients (all Caucasian, 80% male, mean age 59 years) with myocardial infarction (MI) during the acute treatment phase. Interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, IL-4, IL-10, and transforming growth factor (TGF)-1β were determined in plasma collected within 48 h of hospital admission. Participants self-assessed the severity of ACS-induced PTSD symptoms with the 17-item Posttraumatic Diagnostic Scale at 12 months. ResultsThere was a significant positive association of the pro-inflammatory index (added standardized z-scores of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α) with total PTSD symptom severity (ΔR2 = 0.050, p = .029) and re-experiencing symptoms (ΔR2 = 0.088, p = .008), but not avoidance/numbing and hyperarousal symptoms. Analyses were adjusted for the anti-inflammatory index (added standardized z-scores of IL-4, IL-10, and TGF-β1), trauma-focused counseling, sex, age, time since pain onset, troponin, body mass index, and distress during MI. Results were robust when the anti-inflammatory index was removed from the model. Additional analyses showed significant associations of both the net-inflammatory index (i.e., pro-inflammatory index minus anti-inflammatory index) and IL-1β with total PTSD symptom severity, re-experiencing, and hyperarousal symptoms (ΔR2 between 0.042 and 0.090) and of IL-1β with avoidance/numbing symptoms (ΔR2 = 0.050). ConclusionsThe findings suggest an association between the pro-inflammatory state launched during ACS and the development of PTSD symptoms. Increased IL-1β may play a particular role in the pathophysiology of ACS-induced PTSD symptoms.

Post-traumatic stress disorder in healthcare workers of emergency departments during the pandemic: A cross-sectional study.

Emergency departments (EDs) were the first application center for Covid-19 patients, as in almost all diseases. For this reason, a serious mental burden has arisen for ED workers. This study was conducted to determine the possible rate of Posttraumatic Stress Disorder (PTSD) and factors that may be associated with PTSD symptom severity in physicians and nurses working in EDs. This cross-sectional study was conducted with a total of 783 participants, including 406 physicians and 377 nurses working in EDs. The PTSD Checklist for DSM-5; Depression, Anxiety and Stress Scale-21; and a structured questionnaire on sociodemographic and work-related characteristics were administered to the participants. The probable PTSD rate in the total sample was found to be 19.2%. The rate of probable PTSD in physicians (22.9%) was significantly higher than in nurses (15.1%). However, PTSD symptom total scores and PTSD symptom clusters were higher in physicians than in nurses, but there was no difference between the two groups in terms of depression, anxiety and stress levels. High anxiety level, being diagnosed with COVID-19, high depression level, female gender, and having additional chronic disease were predictors of high PTSD symptom severity in physicians. For nurses, high anxiety level, being diagnosed with COVID-19, working with 24-h shifts, high depression level, low work experience (years), low monthly income and having additional chronic disease were the predictors of high PTSD symptom severity. The results of our study showed that both profession groups are at risk for PTSD, and contrary to the existing literature, this rate may be higher in physicians than in nurses. HCWs in the EDs needed protective and supportive mental health models in terms of PTSD.

Acute White Matter Integrity Post-trauma and Prospective Posttraumatic Stress Disorder Symptoms.

Background: Little is known about what distinguishes those who are resilient after trauma from those at risk for developing posttraumatic stress disorder (PTSD). Previous work indicates white matter integrity may be a useful biomarker in predicting PTSD. Research has shown changes in the integrity of three white matter tracts—the cingulum bundle, corpus callosum (CC), and uncinate fasciculus (UNC)—in the aftermath of trauma relate to PTSD symptoms. However, few have examined the predictive utility of white matter integrity in the acute aftermath of trauma to predict prospective PTSD symptom severity in a mixed traumatic injury sample.Method: Thus, the current study investigated acute brain structural integrity in 148 individuals being treated for traumatic injuries in the Emergency Department of a Level 1 trauma center. Participants underwent diffusion-weighted magnetic resonance imaging 2 weeks post-trauma and completed several self-report measures at 2-weeks (T1) and 6 months (T2), including the Clinician Administered PTSD Scale for DSM-V (CAPS-5), post-injury.Results: Consistent with previous work, T1 lesser anterior cingulum fractional anisotropy (FA) was marginally related to greater T2 total PTSD symptoms. No other white matter tracts were related to PTSD symptoms.Conclusions: Results demonstrate that in a traumatically injured sample with predominantly subclinical PTSD symptoms at T2, acute white matter integrity after trauma is not robustly related to the development of chronic PTSD symptoms. These findings suggest the timing of evaluating white matter integrity and PTSD is important as white matter differences may not be apparent in the acute period after injury.
