Evolving DSM Diagnostic Criteria for PTSD: Relevance for Assessment and Treatment

A Scoping Review of PTSD and Depression in Adult Burn Patients: A Call for Standardized Screening and Intervention Research

Despite the growing incidence of burn injuries globally and the advancements in physical recovery, the psychological aspect of burn trauma recovery remains inadequately addressed. This review aims to consolidate existing literature on posttraumatic stress disorder (PTSD) and depression in adult burn survivors, recognizing the need for a holistic approach to burn recovery that encompasses both physical and mental health. The comprehensive analysis of 156 studies revealed significant variations in methodological approaches, leading to challenges in creating standardized protocols for mental health assessment in burn care. Key findings include the identification of a wide range of psychological assessment tools and a substantial research gap in low- and middle-income countries, where the majority of burn injuries occur. Only 7.0% of the studies assessed interventions for PTSD or depression, indicating a lack of focus on treatment modalities. The studies identified demographic factors, patient history, psychosocial factors, burn injury characteristics, and treatment course as risk factors for PTSD and depression postburn injury. The review highlights the need for early screening, intervention, and attention to subjective experiences related to burn injury, as these are strong predictors of long-term psychological distress. It also emphasizes the complexity of addressing psychological distress in burn survivors and the need for more standardized practices in assessing PTSD and depression specific to this population.

Posttraumatic growth-oriented peer-based training among U.S. veterans: evaluation of post-intervention and long-term follow-up outcomes

Introduction

Exposure to trauma among U.S. military veterans occurs at a high rate, often resulting in continued difficulty with emotional adjustment and a diagnosis of posttraumatic stress disorder (PTSD). The present study provides data from 184 U.S. military veterans who completed a manualized posttraumatic-growth oriented training program during an integrative seven-day retreat.

Methods

Data was collected at baseline, after program completion, and at 18-month follow-up.

Results

Results on primary outcomes indicated significant increases, with medium to large effect sizes, in growth related outcomes. Specifically, there was a significant increase in scores by 54% on the posttraumatic growth outcome measure (PTGI-X) from baseline (M = 50.2, SD = 31.1) to endpoint (M = 77.4, SD = 29.6), t(183) = -8.78, p < 0.001. Also, results indicate that immediately following training (Day 7), participants reported a significant decrease of 49% on the PCL-5 from baseline (M = 39.7, SD = 17.6) to endpoint (M = 20.1, SD = 13.2), t(183) = 11.75, p < 0.001. Depression subscale scores decreased by 60% from baseline (M = 8.0, SD = 5.2) to endpoint (M = 3.2, SD = 3.0), t(183) = 10.68, p < 0.001; Anxiety scores decreased by 28% from baseline (M = 5.8, SD = 4.3) to endpoint (M = 4.2, SD = 3.5), t(183) = 4.08, p < 0.001; and Stress scores decreased by 50% from baseline (M = 10.0, SD = 4.4) to endpoint (M = 5.0, SD = 3.3), t(183) = 12.21, p < 0.001. Eighteen-month follow-up data was available for 74 participants and indicated that all significant changes in growth-related outcomes were maintained. Further, all significant changes in symptomatology-related outcomes were also maintained at follow-up.

Discussion

These findings demonstrate both the immediate and the long-lasting impact of an integrative posttraumatic growth-oriented training program on psychological growth and PTSD symptom reduction among U.S. military veterans.

Longing for sleep after violence: The impact of PTSD symptoms, avoidance, and pain on insomnia among female veterans

Women survivors of intimate partner violence often struggle with mental and physical problems that arise from incidents of violence. Beyond posttraumatic stress disorder (PTSD), the most common outcome, women also may suffer from debilitating chronic pain due to physical injuries sustained during particularly violent physical and/or sexual encounters. This may be a key interaction to explore as PTSD can lead to avoidance of distressing experiences, including chronic pain, resulting in enduring medical problems such as extreme sleep difficulties. This study aimed to identify if posttraumatic stress disorder (PTSD) symptoms from intimate partner violence (IPV) experiences had a conditional indirect effect on insomnia via chronic pain severity moderated by experiential avoidance among women. Female Veterans of at least 18 years of age completed online surveys at three timepoints (T1-T3) between 2014 and 2017 that included measures of PTSD, chronic pain, experiential avoidance, and insomnia. A total of 411 women participated in the initial survey at T1; 208 had a lifetime history of IPV experiences. The conditional indirect effect of PTSD symptoms (T1) on insomnia (T3) via chronic pain (T2) contingent upon experiential avoidance (T2) was also significant, demonstrating a significant moderated mediation model. This model was not significant for women without a history of IPV at T1. The findings indicate that women with IPV-related PTSD symptoms who are highly avoidant are more likely to experience chronic pain, leading to worse insomnia. Women without IPV experiences did not exhibit this same pattern. Findings have implications for improving trauma-focused treatment, approach coping strategies, pain management, and sleep interventions to address these deleterious psychological and medical issues.

Neural response to trauma-related and trauma-unrelated negative stimuli in remitted and persistent pediatric post-traumatic stress disorder

INTRODUCTION

Most youths who suffer from post-traumatic stress disorder (PTSD) lose their diagnosis in the first 1-2 years. However, there are few studies on this brain mechanism, and the heterogeneity of the findings is partially due to the different stimuli applied and the mixed trauma history. Therefore, the use of trauma-related/unrelated stimuli to study the remittance mechanism of earthquake-induced PTSD could advance our knowledge of PTSD and inspire future treatment.

METHODS

Thirteen youths with PTSD, 18 remitted participants, and 18 control participants underwent functional magnetic resonance imaging (fMRI), while viewing trauma-related pictures, trauma-unrelated negative pictures, and scrambled pictures.

RESULTS

Under trauma-unrelated condition, the neural activity of the left hippocampus in the remitted group was between the two other groups. Under trauma-related condition, the PTSD and the remitted group exhibited higher neural activity in the right middle occipital gyrus than controls. The remitted group showed higher neural activity in the right parahippocampal gyrus and right lingual gyrus under trauma-related condition than trauma-unrelated condition, while no significant difference was found in PTSD group.

CONCLUSION

PTSD status-related group differences are mainly reflected in the left hippocampus under the trauma-unrelated condition, while the hyperactivity in the right middle occipital gyrus under trauma-related condition could be an endophenotype for PTSD.

Moderators of PTSD symptom change in group cognitive behavioral therapy and group present centered therapy

To examine moderators of change during group-based intervention for Posttraumatic Stress Disorder (PTSD), multilevel models were used to assess trajectories of symptom clusters in male veterans receiving trauma focused Group Cognitive Behavioral Treatment (gCBT; N = 84) or non-trauma focused Group Present Centered Therapy (gPCT; N = 91; Sloan et al., 2018). Separate models were conducted for symptom clusters in each intervention, examining pre-treatment PTSD symptoms, pre-treatment depression severity, age, index trauma, and outcome expectancies as potential moderators. Unconditioned growth models for both gCBT and gPCT showed reductions in intrusions, avoidance, negative cognitions/mood, and arousal/reactivity (all p < .001). Distinct moderators of recovery emerged for each treatment. Reductions in avoidance during gCBT were strongest at high levels of pre-treatment PTSD symptoms (low PTSD: p =  .964, d = .05; high PTSD: p < .001, d = 1.31) whereas positive outcome expectancies enhanced reductions in cognitions/mood (low Expectancy: p =  .120, d = .50; high Expectancy: p < .001, d = 1.13). For gPCT, high levels of pre-treatment depression symptoms negatively impacted change in both intrusion (low depression: p < .001, d = .96; high depression: p =  .376, d = .22) and arousal/reactivity (low depression: p < .001, d = .95; high depression: p =  .092, d = .39) symptoms. Results support the importance of examining trajectories of change and their moderators for specific treatments, particularly when contrasting trauma focused and non-trauma focused treatments.

Prevalence and Determinants of PTSD 3 Years After an Earthquake in Iran

Post-Traumatic Stress Disorder (PTSD) is one of the most debilitating and costly mental health problems that can develop following exposure to natural disasters. Nevertheless, much remains unknown about how to best address PTSD and other mental health needs in disaster-stricken areas, particularly in rural and under-resourced areas. The present study is a population-based cross-sectional study conducted in rural areas that were affected by a destructive earthquake in Iran. The aim of the research is to explore the prevalence and determinants of PTSD among survivors 3 years after the earthquake. A multi-stage cluster random sampling technique was used to obtain a sample of 600 respondents between the ages of 18- and 87-years-old in affected areas. In the present sample, 224 individuals (37.3%) reported some PTSD symptoms. Factors associated with an increased likelihood of developing PTSD included being in a severely-stricken (as opposed to moderately-stricken) village and being female. However, there were no significant associations between PTSD and age groups, marital status, profession, and educational status. These results underscore the need for improved psychosocial interventions following disasters.

A Randomized Controlled Trial of Group Cognitive Behavioral Treatment for Veterans Diagnosed With Chronic Posttraumatic Stress Disorder

Relative to advances in the literature that have examined individual treatment approaches for posttraumatic stress disorder (PTSD), scientific knowledge about group treatment approaches has lagged, resulting in no currently available group treatment for PTSD despite the frequency with which this format is used. Our goal was to build upon the existing literature by examining the efficacy of a group cognitive-behavioral treatment (GCBT) for PTSD relative to group present-centered treatment (GPCT). The sample consisted of 198 male veterans with PTSD who were recruited at two Department of Veteran Affairs medical centers and randomly assigned to either GCBT (n = 98) or GPCT (n = 100); both treatments were 14 sessions. Assessments occurred at baseline, midtreatment, posttreatment, and 3-, 6-, and 12-month follow-ups. Findings indicated significant reductions in PTSD severity and PTSD diagnostic status following treatment for both GCBT, d = 0.97, and GPCT, d = 0.61. In addition, we observed significant reductions for depression symptoms, anxiety symptoms, and functional impairment for both group treatments as well as a reduction in the percentage of veteran participants who met diagnostic status for co-occurring major depression disorder and generalized anxiety disorder. Notably, these treatment gains were maintained at 12-month follow-up. Contrary to expectations, there were no significant differences between treatment conditions. Veterans diagnosed with PTSD were successfully treated using a group approach. Consistent with a growing body of evidence, the findings also suggest GPCT is as equally efficacious as group trauma-focused treatment. The trial was registered at clinicaltrials.gov (NCT01544088).

ICD-11 PTSD and complex PTSD amongst Syrian refugees in Lebanon: the factor structure and the clinical utility of the International Trauma Questionnaire

OBJECTIVE

Support for ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) is growing; however, few studies include refugees or examine the clinical utility of PTSD/CPTSD classifications. This study sought to provide the first evaluations of (i) the factor structure of ICD-11 PTSD/CPTSD amongst refugees in the Middle East; and (ii) the clinical utility of the International Trauma Questionnaire (ITQ) to identify PTSD/CPTSD in a humanitarian context.

METHOD

Participants were 112 treatment-seeking Syrian refugees living in Lebanon. Factorial validity was assessed using confirmatory factor analysis (CFA) based on responses to the ITQ. Clinical utility of the ITQ was assessed through semi-structured interviews with six Lebanese psychotherapists.

RESULTS

Complex PTSD (36.1%) was more common than PTSD (25.2%), and no sex or age differences were observed at the prevalence or symptomatic levels. CFA results supported a two-factor higher-order model consistent with ICD-11 PTSD/CPTSD. Qualitative findings indicated that the ITQ is generally positively regarded, with some limitations and suggested modifications noted.

CONCLUSION

This is the first study to support the ICD-11 PTSD/CPTSD amongst refugees in the Middle East and the clinical utility of the ITQ in a humanitarian context. Findings support the growing evidence for the cross-cultural applicability of ICD-11 PTSD/CPTSD.

Can the dissociative PTSD subtype be identified across two distinct trauma samples meeting caseness for PTSD?

INTRODUCTION

For over a century, the occurrence of dissociative symptoms in connection to traumatic exposure has been acknowledged in the scientific literature. Recently, the importance of dissociation has also been recognized in the long-term traumatic response within the DSM-5 nomenclature. Several studies have confirmed the existence of the dissociative posttraumatic stress disorder (PTSD) subtype. However, there is a lack of studies investigating latent profiles of PTSD solely in victims with PTSD.

PURPOSE AND METHOD

This study investigates the possible presence of PTSD subtypes using latent class analysis (LCA) across two distinct trauma samples meeting caseness for DSM-5 PTSD based on self-reports (N = 787). Moreover, we assessed if a number of risk factors resulted in an increased probability of membership in a dissociative compared with a non-dissociative PTSD class.

RESULTS

The results of LCA revealed a two-class solution with two highly symptomatic classes: a dissociative class and a non-dissociative class across both samples. Increased emotion-focused coping increased the probability of individuals being grouped into the dissociative class across both samples. Social support reduced the probability of individuals being grouped into the dissociative class but only in the victims of motor vehicle accidents (MVAs) suffering from whiplash.

CONCLUSIONS

The results are discussed in light of their clinical implications and suggest that the dissociative subtype can be identified in victims of incest and victims of MVA suffering from whiplash meeting caseness for DSM-5 PTSD.
