Elevated Posttraumatic Stress Symptoms Research Articles

A Pilot Trial of Universal School-Based Mental Health Screening in El Salvador: Traumatic Stress in an Underresourced School Environment.

Salvadoran youth have an elevated risk of trauma exposure and related mental health problems. However, investigations of childhood trauma exposure and mental health sequelae in El Salvador are limited. The present study aimed to (a) explore the prevalence of exposure to potentially traumatic events and symptoms of posttraumatic stress, anxiety, and depression and (b) evaluate the associations between specific trauma types and emotional functioning among Salvadoran youth. A total of 1,296 youth aged 8-21 years from seven public schools completed self-report measures of trauma exposure, posttraumatic stress symptoms (PTSS), anxiety, and depression. Participants reported high levels of trauma exposure, endorsing an average of 3.62 (SD = 2.32) trauma types. In total, 34.5% of participants reported clinically elevated PTSS; fewer youths reported elevated depressive (8.7%) and anxiety symptoms (8.6%). Although boys reported exposure to more trauma types than girls, d = 0.22, girls were more likely to endorse elevated PTSS, V = .11; anxiety, V = .06; and depression, V = .10. Adolescents reported exposure to more trauma types than younger children, d = 0.23, and were more likely to endorse elevated PTSS, V = .07; anxiety, V = .13; and depression, V = .16. Undergoing a frightening medical procedure, OR = 2.30; female sex, OR = 1.92; witnessing domestic violence, OR = 1.70; and experiencing war between gangs, OR = 1.61, were strong predictors of elevated PTSS. This broad, school-based screening was a critical step toward better understanding the rate of trauma exposure and trauma-related symptoms among Salvadoran youth.

Post-traumatic stress symptoms in COVID-19 survivors: a self-report and brain imaging follow-up study.

Previous coronavirus pandemics were associated elevated post-traumatic stress symptoms (PTSS), but the self-report and neurological basis of PTSS in patients who survived coronavirus disease 2019 (COVID-19) are largely unknown. We conducted a two-session study to record PTSS in the COVID-19 survivors discharged from hospitals for a short (i.e., about 3 months, Session 1) to a medium period (i.e., about 6 months, Session 2), as well as brain imaging data in Session 2. The control groups were non-COVID-19 locals. Session 1 was completed for 126 COVID-19 survivors and 126 controls. Session 2 was completed for 47 COVID-19 survivors and 43 controls. The total score of post-traumatic stress disorder (PTSD) checklist for DSM-5 (PCL-5) score was significantly higher in COVID-19 survivors compared with controls in both sessions. The PCL-5 score in COVID-19 survivors was positively correlated with the duration after discharge (r = 0.27, p = 0.003 for Session 1), and increased by 20% from Session 1 to Session 2 for the survivors who participated both sessions. The increase was positively correlated with individual’s test-retest duration (r = 0.46, p = 0.03). Brain structural volume and functional activity in bilateral hippocampus and amygdala were significantly larger in COVID-19 survivors compared with controls. However, the volumes of the left hippocampus and amygdala were negatively correlated with the PCL-5 score for the COVID-19 survivors. Our study suggests that COVID-19 survivors might face possible PTSS deteriorations, and highlights the importance of monitoring mental wellness of COVID-19 survivors.

Vulnerability to COVID-19-Related Disability: The Impact of Posttraumatic Stress Symptoms on Psychosocial Impairment During the Pandemic.

As a result of the COVID–19 pandemic, many individuals have experienced disruptions in social, occupational, and daily life activities. Individuals with mental health difficulties, particularly those with elevated posttraumatic stress symptoms (PTSS), may be especially vulnerable to increased impairment as a result of COVID–19. Additionally, demographic factors, such as age, gender, and race/ethnicity, may impact individual difficulties related to the pandemic. The current study examined the concurrent and prospective associations between posttraumatic stress disorder (PTSD) symptoms, broader anxiety and depression symptoms, and COVID–19–related disability. Participants recruited through Amazon's Mechanical Turk (N = 136) completed questionnaire batteries approximately 1 month apart during the COVID–19 pandemic (i.e., Wave 1 and Wave 2). The results indicated that PTSD, anxiety, and depressive symptoms were all associated with increased COVID–19–related disability across assessment points, rs = .44–.68. PTSD symptoms, specifically negative alterations in cognition and mood, significantly predicted COVID–19–related disability after accounting for anxiety and depressive symptoms as well as demographic factors, βs = .31–.38. Overall, these findings suggest that individuals experiencing elevated PTSS are particularly vulnerable to increased functional impairment as a result of COVID–19 and suggest a need for additional outreach and clinical care among individuals with elevated PTSD symptoms during the pandemic.

The Parent Version of the Sensitivity to Pain Traumatization Scale (SPTS-P): A Preliminary Validation.

Sensitivity to pain traumatization (SPT) is defined as the propensity to develop responses to pain that resemble a traumatic stress reaction. To date, SPT has been assessed in adults with a self-report measure (Sensitivity to Pain Traumatization Scale (SPTS-12)). SPT may also be relevant in the context of parenting a child with chronic pain, as many of these parents report clinically elevated posttraumatic stress symptoms (PTSS). This study aimed to develop and validate a measure of parent SPT by adapting the SPTS-12 and evaluating its psychometric properties in a sample of parents whose children have chronic pain. In total, 170 parents (90.6% female) and children (aged 10–18 years, 71.2% female) were recruited from a tertiary chronic pain program. Parents completed the parent version of the SPTS-12 (SPTS-P) and measures of PTSS, depression, anxiety and anxiety-related constructs, and parenting behaviors. Youth completed measures of pain. Consistent with the SPTS-12, the SPTS-P demonstrated a one-factor structure that accounted for 45% of the variance, adequate to good reliability and moderate construct validity. Parent SPT was positively related to their protective and monitoring behaviors but was unrelated to youth pain intensity, unpleasantness, and interference. These results provide preliminary evidence for the psychometric properties of the SPTS-P and highlight the interaction between parent distress about child pain and parent responses to child pain.

Gender Differences in Traumatic Experiences and Posttraumatic Stress Symptoms After the Rwandan Genocide Against the Tutsi.

The effects of the 1994 Rwandan Genocide against the Tutsi are widespread and long-lasting, but little is known about how posttraumatic consequences differ regarding gender. In the present study, we estimated the associations between trauma exposure and posttraumatic stress symptoms (PTSS) in a Rwandan community sample and examined whether the associations differed by gender. The sample comprised 498 adults (75.2% women) living in Rwanda's Huye District in 2011. We used a validated self-report checklist to assess the eight most frequent traumatic experiences during the Genocide. The PTSD Checklist-Civilian version (PCL-C) was used to assess PTSS. Associations between trauma exposureand PTSS were estimated using structural equation modeling (SEM), with additional SEMs stratified by gender. The prevalence of exposure to each traumatic event ranged from 15.1% to 64.5%, with more severe PTSS among individuals who reported personal physical injury, β = .76, 95% CI [0.54, 0.98]; witnessing sexual/physical violence against a loved one, β = .51, 95% CI [0.20, 0.81]; a close relative/friend's death, β = .54, 95% CI [0.24, 0.83]; property destruction, β = .35, 95% CI [0.048, 0.51]; or a family member's death due to illness, β = .21, 95% CI [0.00, 0.41]. Men who saw people killed and women who witnessed sexual/physical violence against a close family member reported elevated PTSS. The psychiatric impact of the Rwandan Genocide continues into the 21st century. Increased attention should be paid to the long-term and demographic patterns of distress and disorder, especially in the absence of widespread clinical mental health services.

Examining the association of medical complications and posttraumatic stress symptoms in pediatric solid organ transplant patients and their caregivers.

Post-traumatic stress symptoms (PTSS) have been reported by pediatric solid organ transplant (SOT) patients and their caregivers well after transplantation. This study examined the relationship between PTSS, medication adherence, and medical complications in SOT patients and their caregivers. A secondary aim examined the association between patient and caregiver-reported PTSS. Pediatric SOT patients (N=69) and caregivers (N=73) reported on PTSS by completing the Child PTSD Symptom Scale (patients 8-17years) or the Impact of Events Scale-Revised (patients 18years and older and caregivers). Patient medication adherence was assessed using the Medication Level Variability Index (MLVI). Patients were dichotomized as experiencing a post-transplant medical complication (ie, transplant-related hospital admission prior to the year completing measures of PTSS) or no complications. Medication adherence was not significantly associated with patient or caregiver PTSS. A moderate effect size was found for elevated young adult and caregiver PTSS and the presence of a medical complication. Generally, the association between self-reported patient and caregiver PTSS was low. The presence of elevated PTSS in young adult patients may be partially explained by the presence of proximal medical complications and more so by comorbid psychiatric diagnoses in child and adolescent patients (based on exploratory analyses). Caregivers of patients with medical complications within the past year reported higher levels of PTSS. Overall, transplantation and its associated impact on PTSS may be unique experience for patients versus caregivers. Qualitative research may further elucidate these experiences and inform future clinical interventions.

Parental Posttraumatic Stress Symptoms in the Context of Pediatric Post Intensive Care Syndrome: Impact on the Family and Opportunities for Intervention.

Pediatric intensive care unit (PICU) survivors and their families experience ongoing impacts on physical, cognitive, and psychosocial functioning, described as Post-Intensive Care Syndrome (PICS). The objective of this study was to determine whether the posttraumatic stress symptoms (PTSS) of parents predict the impact of critical illness on families following PICU admission beyond other factors (e.g., sex, race/ethnicity, age, insurance status, illness severity, family involvement or death). We conducted a retrospective analysis of data from 88 children aged 1 month to 18 years who were hospitalized with critical illness and acquired brain injury in the PICU and their families. Patients and their families participated in a 1-3 month post-discharge follow-up assessment, during which data on demographics, medical diagnoses, parent self-report of PTSS, and family impact of critical illness (via the Pediatric Quality of Life Family Impact Module) were collected. We used a hierarchical linear regression to determine whether parent PTSS predicted family impact above and beyond demographic and injury/illness factors. One-third of parents reported elevated PTSS. Among those with complete available data (n = 56), PTSS were the only significant predictor of family impact (β = -.52, t = -3.58, p = .001), with the overall model accounting for 41% of variance. In addition to the direct effects on parents of children who survive the PICU, PTSS may negatively impact families and interfere with rehabilitative progress. We provide a rationale and conceptual model for integrating interventions designed to address parent PTSS into post-PICU care.

A longitudinal investigation of trauma-specific rumination and PTSD symptoms: The moderating role of interpersonal trauma experience

BackgroundInterpersonal trauma (IPT) is one of the most commonly reported types of traumatic experiences and has the greatest likelihood of resulting in a diagnosis of posttraumatic stress disorder (PTSD). Relative to other types of trauma, victims of IPT report greater trauma-specific rumination, whereby they focus on negative consequences of the trauma on their life. Theoretical and empirical work suggest trauma-specific rumination leads to elevated posttraumatic stress symptoms (PTSS); however, there has been a dearth of research examining how trauma type may impact this association. Therefore, the current longitudinal study examined how the experience of IPT moderates the relationship between trauma-specific rumination and later PTSS. MethodParticipants (N = 204) enrolled in a clinical trial completed self-report measures of trauma experience, trauma-specific rumination, and PTSS at baseline and 1-month follow-up appointments. ResultsResults revealed that IPT moderated the relationship between baseline rumination and 1-month trauma symptoms, even after covarying for participant age and sex, treatment condition, negative affect, and number of previously experienced traumas. Further, this moderation effect was specific to the PTSD numbing cluster. LimitationsMajor limitations include measurement of PTSS via PCL-C rather than the PCL-5, as well as a limited sample size, precluding moderation analyses of other trauma types. ConclusionsThe current study provides novel findings demonstrating specificity of index trauma type in the longitudinal relationship between rumination and PTSS. Future work is needed to examine how IPT impacts the development of pathways between rumination and PTSS.

Indirect Associations Between Posttraumatic Stress Symptoms and Other Psychiatric Symptoms, Alcohol Use, and Well-being via Psychological Flexibility Among Police Officers.

Police officers experience a high number of potentially traumatic events (PTEs) often associated with elevated posttraumatic stress symptoms (PTSS). In addition, PTSS are related to co-occurring psychiatric symptoms (e.g., anxiety, depression), alcohol misuse, and low perceived well-being. Yet, behavioral processes that may account for the associations between PTSS and unfavorable outcomes remain unspecified. Psychological flexibility, or one's response to private experiences (e.g., PTE-related memories) with an open, aware, and active approach, may be one such process. The present study aimed to evaluate psychological flexibility as both a mediator and moderator of PTSS and commonly co-occurring psychiatric symptoms, alcohol use, and general well-being, using cross-sectional data provided by a sample of police officers (N = 459) recruited from three regionally distributed U.S. police agencies. Structural equation modeling indicated a well-fitting model wherein psychological flexibility indirectly accounted for associations among PTSS and endogenous outcomes, χ2 (107, N = 457) = 225.33, p < .001, CFI = .99, TLI = .98, RMSEA = .05, 90% CI [.04, .06], SRMR = .03. Psychological flexibility also moderated associations between PTSS and psychiatric symptoms, B = 1.58 (SE = 0.22), p < .001; and well-being, B = -3.84 (SE = 0.46), p < .001. Although additional research is needed, these preliminary results suggest psychological flexibility may be a behavioral process that accounts for negative outcomes associated with PTSS and a productive intervention target in the context of PTSS and generalized distress. Further research regarding the role of psychological flexibility in PTSS-related outcomes for police officers appears warranted.

Profiles of home violence and posttraumatic stress symptoms among young adults: Distinguishing between trauma and adversity using latent class analysis.

Home violence exposure (HVE) varies by type and frequency of exposure, which can lead to uncertainty when determining what is traumatic and what is not, particularly when assessing posttraumatic stress symptoms (PTSS) and disorder (PTSD). The current study examined whether specific types of HVE were associated with specific types of PTSS to help determine what experiences may rise to the level of trauma. Participants included 988 racially and ethnically diverse college students (74.1% women). Two latent class analyses were performed, examining types of HVE and types of PTSS to determine how classifications of HVE were associated with classifications of PTSS. Four classifications of HVE were identified: high exposure (21.7%), vicarious exposure (28.9%), victimization (10.5%), and low exposure (38.9%). Four classifications of PTSS were also identified: high PTSS (20.9%), dysphoric arousal (17.4%), anxious arousal (21.3%), and low PTSS (40.4%). Even when considering other potentially traumatic events, participants with experiences of victimization were 2.55 times more likely than those with low exposure to meet criteria for PTSD. Victimization was uniquely associated with dysphoric arousal as well as all other PTSS. High exposure was associated with high PTSS and anxious arousal, with vicarious exposure associated only with anxious arousal. Findings provide unique evidence for the potentially traumatic effects of victimization in the home. Frequent and cumulative effects of HVE that do not meet DSM criteria for a potentially traumatic event may be associated with elevated PTSS, particularly symptoms of anxious and dysphoric arousal.

Effects of mindfulness training on posttraumatic stress symptoms from a community-based pilot clinical trial among survivors of intimate partner violence.

Objective: Exposure to intimate partner violence (IPV) is a significant public health issue associated with deleterious mental and medical health comorbidities, including posttraumatic stress disorder (PTSD). The hallmark symptoms of posttraumatic stress (PTS), even when not meeting the threshold for a diagnosis of PTSD, appear to be underpinned by poor self-regulation in multiple domains, including emotion, cognitive control, and physiological stress. Mindfulness-based stress reduction (MBSR) holds promise for treating PTS symptoms because evidence suggests it targets these domains. The current study was a pilot randomized clinical trial designed to examine changes in emotion regulation, attentional function, and physiological stress dysregulation among women IPV survivors with elevated PTS symptoms after participation in a group-based, 8-week MBSR program. Method: In total, 29 participants were randomized to receive MBSR (n = 19) or an active control (n = 10). Assessments were conducted at study entry, as well as 8 and 12 weeks later. Results: Between-group differences on primary outcomes were nonsignificant; however, when exploring within groups, statistically significant decreases in PTS symptoms, F(1.37, 16.53) = 5.19, p < .05, and emotion dysregulation, F(1.31, 14.46) = 9.36, p < .01, were observed after MBSR but not after the control intervention. Further, decreases in PTSD and emotion dysregulation were clinically significant for MBSR participants but not control participants. Conclusions: These preliminary data signal that MBSR may improve PTS symptoms and emotion regulation and suggest further study of the effectiveness of PTSD interventions guided by integrative models of MBSR mechanisms and psychophysiological models of stress regulation.

Predisaster predictors of posttraumatic stress symptom trajectories: An analysis of low-income women in the aftermath of Hurricane Katrina.

Exposure to disasters is associated with a range of posttraumatic stress symptom (PTSS) trajectories. However, few studies have tracked PTSS for more than a decade postdisaster, and none to our knowledge has explored the role of predisaster resources and vulnerabilities in shaping the likelihood of trajectory membership. The current study included participants from the Resilience in Survivors of Katrina Study (N = 885). Participants were originally part of a community college intervention study and were assessed prior to the hurricane (6-21 months predisaster), and approximately 1 year, 4 years, and 12 years postdisaster. Latent class growth analysis identified PTSS trajectories. Perceived social support, probable mental illness, and physical health conditions or problems-all assessed predisaster-were examined as predictors of trajectory membership at the univariate level and in multivariable models without and with adjustment for disaster exposure. Three PTSS trajectories were detected: Moderate-Decreasing (69.3%), High-Decreasing (23.1%), and High-Stable (7.6%). In the multivariable predictive model without adjustment for disaster exposure, probable predisaster mental illness was significantly associated with greater odds of the High-Decreasing and High-Stable trajectories, and physical health conditions or problems with greater odds of the High-Decreasing trajectory, relative to the Moderate-Decreasing trajectory. However, when disaster exposure was adjusted, only the association between predisaster mental illness and the odds of the High-Stable trajectory remained statistically significant. Lower predisaster perceived social support was significantly associated with membership in the High-Decreasing trajectory, relative to the Moderate-Decreasing, at the univariate level, but not in either multivariable model. Whereas predisaster mental illness confers risk for chronic postdisaster PTSS, other impacts of predisaster resources and vulnerabilities on elevated PTSS trajectories do not go beyond those of disaster exposure. The results support disaster preparedness efforts targeting those with mental and physical health conditions, and postdisaster mental health services addressing preexisting vulnerabilities in addition to disaster-related PTSS.

Longitudinal course and predictors of posttraumatic stress symptoms after spinal cord injury

Objective This study examined longitudinal changes in post-traumatic stress symptoms (PTSS) in individuals newly diagnosed with spinal cord injury (SCI) and tested various psychosocial and injury-related characteristics as predictors for interindividual differences in symptom courses. Design Longitudinal data from the larger Swiss Spinal Cord Injury Cohort Study were used. The sample consisted of 269 patients (70.6% male; M age = 53.21) admitted for inpatient rehabilitation to SCI rehabilitation centers. Main Outcome Measure PTSS were measured at one and six months after injury using the Impact of Event Scale-6. Results Latent change score modelling revealed no average change in PTSS in the sample, but significant variability in the individual symptom courses. Reliable change index analyses suggest that among individuals with an initial PTSS severity of clinical concern (n = 65), only 27.7% showed clinically significant decreases over time. Predictors explained 34% of the variance in PTSS change. Loss appraisals (β = .30, p < .001) and cause of injury (β = .16, p = .018) emerged as unique predictors. Conclusion Clinically elevated PTSS one month after SCI typically remain across the following months highlighting the need for early screening and intervention. Low loss appraisals were related to decreases in symptom severity and might therefore be a suitable intervention target for reducing PTSS after SCI.

Posttraumatic Stress Symptoms and Coping Motives Mediate the Association Between Childhood Maltreatment and Alcohol Problems.

Childhood maltreatment is associated with increased risk of alcohol misuse. Posttraumatic stress symptoms (PTSS) and coping motives have both been identified, separately, as mediators of the relation between childhood maltreatment and alcohol misuse but have yet to be examined as serial mediators in a high-risk population. A total of 564 adolescents (53.7% female; M age = 15.9 years, SD = 1.1) in the care of child welfare services completed validated measures of childhood trauma, PTSS, drinking motives, and alcohol misuse across the first two waves (baseline and 6-month follow-up) of the Maltreatment and Adolescent Pathways (MAP) longitudinal study. Childhood maltreatment was associated with elevated PTSS, PTSS predicted higher coping motives, and coping motives were associated with higher levels of alcohol misuse, indirect effect (IE) = 0.03; 95% CI [0.00, 0.07]. Single mediator models with PTSS, IE = 0.03; 95% CI [-0.01, 0.05], and coping motives, IE = -0.02, 95% CI [-0.05, 0.03], as mediators were not statistically significant. The results suggest that PTSS and coping motives contribute sequentially to the association between childhood maltreatment and alcohol misuse and could thus both serve as intervention targets to prevent problem drinking in maltreated youth.

Trajectories of tornado-related posttraumatic stress symptoms and pre-exposure predictors in a sample of at-risk youth.

The current study examined how severity of disaster exposure and predisaster individual and family characteristics predicted trajectories of disaster-related posttraumatic stress symptoms (PTSS) in children over 4 years following a devastating EF-4 tornado. Participants (n = 346; 65% male; 77.5% African American) were 4th-6th-graders and their caregivers, from predominantly low-income households, who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Latent class trajectory analyses were used to identify disaster-related PTSS trajectory groups across the 4-year postdisaster period. Three groups were identified: (1) a group that declined (recovery) in PTSS over time (15.90%); (2) a group that was stable and low in PTSS over time (76.87%); and (3) a group that was stable and high (chronic) in PTSS over time (7.23%). Multinomial logistic regression analyses revealed that greater tornado exposure predicted membership in the declining trajectory group relative to the low-stable group. Positive parenting and pretornado caregiver trauma exposure also moderated how disaster exposure, particularly perceived life threat, predicted PTSS trajectories. Some youth reported elevated disaster-related PTSS repeatedly for 4 years following a devastating tornado. Consistent with the concept of equifinality, results suggest that there are several pre-exposure risk factors that may increase risk for a chronic PTSS trajectory following disaster exposure.

Emotional Reactivity as a Vulnerability for Psychogenic Nonepileptic Seizures? Responses While Reliving Specific Emotions.

Dysfunction in emotional processes is a hypothesized contributor to functional neurological disorders (FNDs), yet few studies have evoked real-time emotion during multimethod assessment incorporating subjective, behavioral, and psychophysiological indicators. This approach may reveal clinical and neurobiological vulnerability to FND and clarify how dysfunctional emotional processes serve as perpetuating factors. Eleven participants with video-EEG-confirmed diagnoses of psychogenic nonepileptic seizures (PNES) were compared with 49 seizure-free trauma control subjects (TCs) with or without clinically elevated posttraumatic stress symptoms (25 clinically elevated [TC-clin], 24 not clinically elevated [TC-nonclin]). Participants recalled and described memories evoking anger, shame, happiness, and neutral feelings. Even though PNES patients and TCs reported similar amounts of emotional experience, PNES patients reported more difficulty reliving emotions and were less likely to complete the relived shame task. During and after reliving happiness, PNES and TC-clin groups showed respiratory sinus arrhythmia (RSA) decreases, indicating parasympathetic withdrawal, whereas the TC-nonclin group showed RSA increases. Findings from this pilot study are consistent with previous research and clinical observations that emotional engagement may be more effortful for PNES patients. Patterns of RSA change, which may also point to greater effortful engagement, were similar in PNES and TC-clin groups, suggesting that traumatic stress reactions may play a part. At the same time, experience of greater difficulty or avoidance may be even greater among PNES patients. Especially when regulatory resources are already limited, accumulated effort, coupled with self-threatening contexts such as shame, may be particularly problematic for those with PNES and perhaps other FNDs.

Change Across Time in Cancer-Related Traumatic Stress Symptoms of Siblings of Children with Cancer: A Preliminary Investigation

This pilot study examined changes in cancer-related post-traumatic stress symptoms (PTSS) across time for siblings of children with cancer. Siblings (N = 32; aged 8-18) completed a measure of anxiety, the Child PTSD Symptom Scale (CPSS), and the PTSD section of the Structured Clinical Interview for DSM-IV-TR (SCID) at twelve (SD = .9) and eighteen months (SD = 1.3) post-diagnosis. Moderate-to-severe PTSS was reported by 12 siblings (38%) at T1 and 7 (22%) at T2. Cluster analysis of PTSS data revealed five patterns: Few symptoms, stable across time (31%, n = 10); Mild symptoms, decreasing across time (16%, n = 5); Mild, stable symptoms (28%, n = 9); Moderate/severe symptoms, decreasing across time but remaining moderate (19%, n = 6); and Moderate/severe, stable symptoms (6%, n = 2). SCID data and anxiety scores distinguished siblings in the final two clusters from those with more favorable PTSS levels/trajectories. Additional research with larger samples is needed to validate these trajectories and examine factors that distinguish siblings with consistently elevated cancer-related PTSS from those with mild or significantly improving symptoms.

Predictors of Posttraumatic Stress Symptom Trajectories Following the Fatal 2011 Christchurch, New Zealand Earthquake.

People respond differently to potentially traumatic events. To explore predictors of a chronic and delayed trajectory of posttraumatic stress symptoms (PTSS) after a natural disaster, we analyzed psychometric data collected from 412 residents of Christchurch, New Zealand after a 6.3 magnitude earthquake struck in February 2011. Participants from suburbs with different levels of socioeconomic status (SES) and earthquake impact completed a door-to-door survey 4-7 months after the earthquake (Time 1; N = 600) and again 10-11 months after the earthquake (Time 2; N = 412). The survey included the Acute Stress Disorder Scale, the Patient Health Questionnaire's nine-item Depression subscale, and the Generalized Anxiety Disorder-7 scale, along with single-item measures of variables including aftershock anxiety and family tension. Hobfoll's conservation of resources theory was used to guide data interpretation. High levels of depression, odds ratio (OR) = 1.24, and anxiety, OR = 1.24, at Time 1 significantly predicted membership in the chronic trajectory. Predictors of a delayed onset of symptoms included increased aftershock anxiety, OR = 1.29, and family tension, OR = 1.35, over time, as well as living in an area defined as being of low, OR = 5.36, or medium, OR = 11.39, SES. Results highlight risk factors for elevated PTSS and resources that individuals can use to offset threatened loss. These findings have implications for service providers, agencies, and the public.

Peritraumatic distress among emergency medical system employees: A proposed cut-off for the Peritraumatic Distress Inventory.

Emergency medical system (EMS) workers are exposed to traumatic events that may lead to posttraumatic stress disorder (PTSD). The purpose of this study was to explore and discuss the relationship between peritraumatic distress (PD) and elevated posttraumatic stress symptoms (PTSS) in EMS employees. A cross-sectional study including 100 EMS employees was conducted. Demographic and occupational data were collected for each subject. The Polish version of the Impact of Event Scale-Revised (IES-R) was used to evaluate PTSS and the Polish version of the Peritraumatic Distress Inventory (PDI) was used to determine the level of PD experienced during and immediately after a traumatic event. The highest scores indicative of distress were obtained on the negative emotions subscale, and the lowest on the loss of control and arousal (LCA) subscales. A strong positive correlation was found between the severity of PD and PTSS. Among the PDI subscales, the severity of PTSS was most strongly correlated with LCA, and had the weakest correlation with sense of threat. The optimal PDI cut-off score for predicting elevated PTSS was 19. PD is strongly related to elevated PTSS and serves as a useful tool for screening EMS workers at risk of developing PTSD. Individuals with PDI scores of 19 or higher are good candidates for specialist consultations aimed at detecting and treating elevated PTSS.

The role of sleep quality on the relationship between posttraumatic stress symptoms and pain in women.

Pain frequently co-occurs with elevated posttraumatic stress symptoms (PTSS); women are at elevated risk for their co-occurrence. PTSS and pain are associated with poor sleep quality; yet, little research has examined how sleep impacts their co-occurrence. The current study examines the indirect role of sleep on the relationship between PTSS and pain. A community sample of 182 women completed psychometrically-sound questionnaires assessing PTSS, sleep quality, pain characteristics, depression and anxiety symptoms, and anxiety sensitivity. We examined how sleep quality impacted associations among PTSS and pain intensity and pain interference, while controlling for key psychological factors. Greater PTSS was associated with worse pain interference, and poor sleep quality had a significant indirect effect on this relationship. Sleep may represent a modifiable behavioral mechanism that contributes to the mutual maintenance of PTSS and pain in women. Future research is needed to further clarify the role of sleep quality in their co-occurrence.
