Do psychological treatments for PTSD in children and young people reduce trauma-related appraisals? A systematic review and meta-analysis

Research is increasingly highlighting the role of negative trauma-related appraisals in child and adolescent post-traumatic stress disorder (PTSD). The cognitive model of PTSD claims that an essential mechanism of treatment is a reduction in these appraisals. The current systematic review with meta-analysis investigated the extent to which psychological treatments for PTSD reduce negative trauma-related appraisals in children and adolescents. Four databases (PsycINFO, Medline Complete, CINAHL Complete and PTSDpubs) were searched on the 11-12th December 2022. The Risk of Bias 2 (ROB-2) tool was used to assess for risk of bias. Thirteen studies were included in this review, comprising 937 child and adolescent participants. Using a random effects model to perform the meta-analysis, a medium pooled effect size for the effect of current treatments on trauma-related appraisals was found (g = -.67, 95% CI [-.86, -.48]). There was only a moderate level of heterogeneity between studies (I2 = 44.4%), increasing the confidence with which these findings can be interpreted. These results indicate that psychological treatments for child and adolescent PTSD significantly reduce negative trauma-related appraisals. However, it is important to note that no trial included in the review was categorised as having low risk of bias.

Dissociative Subtype of Posttraumatic Stress Disorder and its Correlates Among Treatment-Seeking Refugees

The dissociative subtype of posttraumatic stress disorder (PTSD-DS) denotes a severe type of PTSD associated with complex trauma exposure and psychiatric comorbidity. Refugees may be at heightened risk of developing PTSD-DS, but research is lacking. This cross-sectional study aimed to examine PTSD-DS and its demographic, trauma-related, and clinical correlates among a convenience sample of refugee patients over 18 years old who were diagnosed with PTSD according to DSM-5. PTSD-DS (Clinician-Administered PTSD Scale for DSM-5), trauma exposure (Life Events Checklist for DSM-5) and general psychopathology (Brief Symptom Inventory) were assessed at intake. T-tests, chi-square tests, and logistical regression analysis were conducted. The final sample consisted of 552 participants (177 (32.1%) women; 375 (67.9%) men; average age 40.0 years (SD = 11.2)) who originated from 63 countries. Of those, 158 (28.6%) met criteria for PTSD-DS. Participants with PTSD-DS scored significantly higher on PTSD symptom severity (t(550)=-5.270, p < .001), number of traumatic event types (t(456)=-3.499, p < .001), and exposure to sexual assault (χ(1) = 6.471, p = .01) than those without PTSD-DS. The odds of having PTSD-DS increased by 14.1% with exposure to each additional traumatic event type (OR = 1.141, CI 0.033-1.260). In conclusion, around 29% of adult treatment-seeking refugees with PTSD met the criteria for PTSD-DS. Those exposed to multiple traumatic event types including sexual assault, regardless of sex, were especially at risk. Having PTSD-DS was associated with more severe PTSD. Prioritizing trauma-focused treatment for those with PTSD-DS is recommended.

The effect of earthquake exposure on PTSD symptoms is mediated by intrusive rumination and moderated by gender: a cross-sectional study on the 2023 Kahramanmaraş earthquake survivors

BACKGROUND

Evidence suggests that natural disasters, such as earthquakes, can lead to post-traumatic stress disorder (PTSD), with women being particularly vulnerable. However, there is a dearth of knowledge about the underlying mechanisms linking traumatic experiences to PTSD as well as gender differences in the operation of these mechanisms. This study examined the mediating effect of intrusive rumination and the moderating effect of gender on the relationship between earthquake exposure level and PTSD symptoms.

METHODS

This cross-sectional study was conducted 12 months after the devastating earthquake in Kahramanmaraş, Turkey. The sample included 632 adult survivors of the earthquake, including 374 females (59.2%) and 258 males (40.8%). Participants completed a set of questionnaires assessing their demographic information, level of earthquake exposure, intrusive rumination, and PTSD symptoms. Correlation analysis, mediation analysis, and conditional process analysis were employed to evaluate the research hypotheses.

RESULTS

Findings revealed significant associations between the level of earthquake exposure, intrusive rumination and PTSD symptoms. The level of earthquake exposure significantly predicted PTSD symptoms. Moreover, intrusive rumination partially mediated the relationship between earthquake exposure level and PTSD symptoms. Additionally, the mediating effect of intrusive rumination was more pronounced among females than males.

CONCLUSION

This study revealed the significant mediating role of intrusive rumination in the development of post-earthquake PTSD symptoms. By uncovering gender differences in this mechanism, it also emphasized the importance of designing interventions that are sensitive to the varying needs of different demographic groups affected by the disaster in post-disaster mental health interventions.

The cumulative contribution of direct and indirect traumas to the production of PTSD

OBJECTIVE

Posttraumatic Stress Disorder (PTSD) affects millions of people worldwide. While the relationship between direct exposure to traumatic events and PTSD is well-established, the influence of indirect trauma exposure on PTSD remains unclear. It is similarly unclear what role cumulative exposure to direct and indirect traumas play in the risk of PTSD.

METHODS

The study uses data from the Houston Trauma and Recovery Study, conducted on 2020-2021, and involved a random sampling of 1,167 individuals residing in Houston during Hurricane Harvey in 2017. Participants were asked about their experiences related to both Hurricane Harvey and the subsequent COVID-19 pandemic. Exposures were categorized as direct or indirect traumas, in line with the criteria delineated in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Cumulative exposures were also calculated.

RESULTS

Among participants, 12.6% were experiencing current PTSD. There were significant associations between both direct [OR = 3.18, 95% CI 1.85, 5.46] and indirect [OR = 1.91, 95% CI 1.05, 3.46] traumas related to Harvey, as well as direct [OR = 2.13, 95% CI 1.20, 3.77] and indirect [OR = 1.69, 95% CI 0.93, 3.09] traumas due to COVID and the risk of PTSD in fully adjusted models. Further, significant associations were found between the cumulative exposure to traumas from both Hurricane Harvey and COVID-19 and the risk of PTSD, considering both direct [OR = 2.53, 95% CI 1.36, 4.70] and indirect exposures [OR = 2.79, 95% CI 1.47, 5.28].

CONCLUSIONS

Our study offers support for connections between exposure to both direct and indirect traumas stemming from large-scale disasters and PTSD. Moreover, we show that cumulative exposures to multiple large-scale events increase the risk of PTSD. This highlights the importance of the consideration of a range of exposures as risks for PTSD, particularly in a time of compounding disasters and broad population exposures to these events.

Childhood Maltreatment and Amygdala-Mediated Anxiety and Posttraumatic Stress Following Adult Trauma

Background

Childhood abuse (physical, emotional, and sexual) is associated with aberrant connectivity of the amygdala, a key threat-processing region. Heightened amygdala activity also predicts adult anxiety and posttraumatic stress disorder (PTSD) symptoms, as do experiences of childhood abuse. The current study explored whether amygdala resting-state functional connectivity may explain the relationship between childhood abuse and anxiety and PTSD symptoms following trauma exposure in adults.

Methods

Two weeks posttrauma, adult trauma survivors (n = 152, mean age [SD] = 32.61 [10.35] years; women = 57.2%) completed the Childhood Trauma Questionnaire and underwent resting-state functional magnetic resonance imaging. PTSD and anxiety symptoms were assessed 6 months posttrauma. Seed-to-voxel analyses evaluated the association between childhood abuse and amygdala resting-state functional connectivity. A mediation model evaluated the potential mediating role of amygdala connectivity in the relationship between childhood abuse and posttrauma anxiety and PTSD.

Results

Childhood abuse was associated with increased amygdala connectivity with the precuneus while covarying for age, gender, childhood neglect, and baseline PTSD symptoms. Amygdala-precuneus resting-state functional connectivity was a significant mediator of the effect of childhood abuse on anxiety symptoms 6 months posttrauma (B = 0.065; 95% CI, 0.013-0.130; SE = 0.030), but not PTSD. A secondary mediation analysis investigating depression as an outcome was not significant.

Conclusions

Amygdala-precuneus connectivity may be an underlying neural mechanism by which childhood abuse increases risk for anxiety following adult trauma. Specifically, this heightened connectivity may reflect attentional vigilance for threat or a tendency toward negative self-referential thoughts. Findings suggest that childhood abuse may contribute to longstanding upregulation of attentional vigilance circuits, which makes one vulnerable to anxiety-related symptoms in adulthood.

Examining PTSD Prevalence Among Underserved Populations in the Integrated Community Mental Health Setting 2019 to 2022

BACKGROUND

The prevalence of Post Traumatic Stress Disorder (PTSD) has been rising since the start of the COVID-19 pandemic, and affects females, sexual and gender minorities, and individuals with social risks at higher rates.

OBJECTIVE

This study examines if the prevalence of PTSD increased from 2019 to 2022 among patients who received care in a national network of safety-net, community-based health centers with integrated behavioral health programs that serve patients at high risk for PTSD.

METHODS

We analyzed electronic health record data from patients with 1 or more behavioral health visits during 2019 to 2022 using repeated cross-sectional data to visualize trends. Change in PTSD prevalence based on the diagnoses associated with each visit from 2019 to 2022 was assessed using a general linear mixed model adjusted for patient-level factors.

RESULTS

Over 4 years, 182 419 distinct patients received care for PTSD, with prevalence increasing from 2019 to 2022 (OR = 1.09, 95% CI = 1.08, 1.10). Females (OR = 1.81, 95% CI = 1.78, 1.84), LGBTQIA individuals (OR = 1.29, 95% CI = 1.26, 1.33), gender diverse individuals (OR = 1.36, 95% CI = 1.29, 1.42), and patients who reported 1 or more social determinants of health needs (OR = 1.52, 95% CI = 1.46, 1.57) were more likely to have a diagnosis of PTSD.

CONCLUSIONS

In a worrying trend, PTSD prevalence has increased among people receiving integrated behavioral health care at community-based health centers, with disparities observed in subpopulations. Continued effort and investment are needed to meet this increasing need in safety-net settings, particularly for those subpopulations observed to have higher prevalence.

The posttraumatic cognitive appraisal inventory (PTCAI): development and validation

Objective

This study aims to develop and validate the Posttraumatic Cognitive Appraisal Inventory (PTCAI) for accidental trauma survivors.

Method

Based on interviews and expert feedback, the initial item pool was generated for the Negative Cognitive Appraisal Inventory of Loss and Feeling Threatened, and the Positive Cognitive Appraisal Inventory of Positively Face, Self-Sense, and Relationships. Then, we recruited two groups of accidental trauma survivors to examine the reliability and validity of the PTCAI. Item analysis and exploratory factor analysis (EFA) were conducted on Sample 1. Confirmatory factor analysis (CFA), Pearson correlation analysis, and internal consistency reliability analysis were applied to Sample 2. After 2 weeks, 20 survivors completed the PTCAI again to test temporal stability.

Results

Following item analysis, the PTCAI was reduced to 27 items. The results of the EFA demonstrated that the five-factor, 27-item solution of the PTCAI was appropriate, which accounted for 63.931% of the total variation. The CFA indicated that the five-factor second-order model offered an excellent fit to the data. Loss and Feeling threatened were equally important in the study participants' negative cognitive appraisal of accidental traumas. Self-sence was the most important positive cognitive appraisal of accidental traumas by the study participants. Positively Face and Relationships were somewhat behind. Additionally, the PTCAI demonstrated high concurrent validity and reliability (test-retest and internal consistency).

Conclusion

The PTCAI appears to be a reliable and valid instrument for assessing cognitive appraisals of accidental trauma survivors.
