Exposure Versus Cognitive Restructuring Techniques in Brief Internet-Based Cognitive Behavioral Treatment for Arabic-Speaking People With Posttraumatic Stress Disorder: Randomized Clinical Trial

Digital health-based exposure therapies for patients with posttraumatic stress disorder: A systematic review of randomized controlled trials

Although exposure therapies have established effects in treating posttraumatic stress disorder (PTSD), these therapies might be hindered by issues of cost, distance, time, and human resources, which are potentially alleviated by digital health. Despite the potential of digital health, there is currently no systematic review specifically evaluating digital health-based exposure therapies. We aimed to conduct a systematic literature review of randomized controlled trials (RCTs) examining the impact of digital health-based exposure therapies in treating patients with PTSD. A literature search was conducted from December 31, 2023, to February 22, 2024, using the PubMed, Web of Science, and PsycINFO databases. A total of 12 RCTs with 1,361 participants were included in the systematic review. These RCTs were conducted mainly in the United States and primarily enrolled military samples. Overall, the utility of digital health-based exposure therapies appeared plausible and comparable to that of in-person therapies. The dropout rate was counterintuitively high, potentially due to technological issues and the absence of personal connections. The findings suggest that digital health-based exposure therapies may potentially resolve the issues of cost, distance, time, and human resources in the treatment of patients with PTSD. Future RCTs should employ larger sample sizes. Addressing technological challenges and the absence of personal connection may be important in resolving the high dropout rate.

Changes in trauma appraisal during brief internet-based exposure and cognitive restructuring treatment for Arabic-speaking people with PTSD

Background: Maladaptive trauma appraisal plays an important role in the development and maintenance of posttraumatic stress disorder (PTSD). While studies have demonstrated the effectiveness of exposure and cognitive treatments for PTSD symptomatology, the effect of such treatments on specific trauma appraisals is still not well understood.Objective: The study investigated the effect of an exposure and a cognitive restructuring internet-based treatment on specific trauma appraisals in Arabic-speaking participants with PTSD.Method: 334 participants received either an exposure (n = 167) or a cognitive restructuring (n = 167) internet-based treatment. PTSD symptom severity (PCL-5) and specific trauma appraisals (TAQ) were assessed at pre- and post-treatment. Changes in specific trauma appraisals within and between the two treatments were analyzed using multi-group change modelling. Associations between changes in PTSD symptom severity and changes in trauma appraisals were evaluated using Pearson product-moment correlation. For both treatments, participants with versus without reliable improvement were compared regarding changes in specific trauma appraisals using Welch tests. Analyses were performed on 100 multiple imputed datasets.Results: Both treatments yielded significant changes in shame, self-blame, fear, anger, and alienation (all ps < .001). Changes in betrayal were only significant in the cognitive restructuring treatment (p < .001). There was no evidence of differences between treatments for any specific trauma appraisal. Changes in PTSD symptom severity were significantly associated with changes in trauma appraisals (all ps < .001). In both treatments, participants who experienced reliable improvement in PTSD symptom severity showed significantly larger pre- to post-treatment changes in specific trauma appraisals compared to those without reliable improvement. Again, differences in betrayal were only significant in the cognitive restructuring treatment.Conclusions: The findings indicate that both treatments are effective in reducing trauma appraisals in Arabic-speaking people with PTSD. Changes in trauma appraisal seem to be associated with changes in PTSD symptomatology.Trial registration: German Clinical Trials Register identifier: DRKS00010245.

Patterns of posttraumatic stress symptoms, their predictors, and comorbid mental health symptoms in traumatized Arabic-speaking people: A latent class analysis

Many people from the Middle East and North Africa (MENA) have experienced traumatic events due to human rights abuses, violence, and conflict in the region, with potential psychological consequences including symptoms of posttraumatic stress and comorbid mental health problems. Yet, little is known about how different posttraumatic stress symptoms unfold in Arabic-speaking people who have experienced diverse traumatic events. This study examined latent classes based on posttraumatic stress symptoms, differences across classes concerning comorbid mental health symptoms and quality of life, and several predictors, including sociodemographic characteristics, social support, and trauma-related characteristics. Participants were 5,140 traumatized Arabic-speaking individuals who had registered for an online intervention. Latent class analysis was conducted to identify distinct classes based on DSM-5 posttraumatic stress symptoms. Multinomial logistic regression was used to analyze predictors of class membership. Differences between classes in severity of posttraumatic stress, depressive, anxiety, and somatoform symptoms, as well as quality of life were examined. Five different latent classes were identified: a general high posttraumatic stress symptom class (43.8%), a high posttraumatic stress symptom-low avoidance class (12.8%), a mixed posttraumatic stress symptom class (20.9%), a high dysphoric-low reexperiencing/avoidance class (14%), and a general low posttraumatic stress symptom class (8.4%). The classes differed in severity of posttraumatic stress, depressive, anxiety and somatoform symptoms, and quality of life. Consistent significant predictors of class membership were gender, social support, cumulative trauma exposure, sexual violence and direct exposure during the most distressing trauma, as well as time since the most distressing trauma. Distinct symptom classes with quantitative and qualitative differences can emerge following exposure to trauma among help-seeking Arabic-speaking people from the MENA region, with gender, social support, and trauma-related characteristics predicting symptom presentation. The results have implications for identifying distressed people and enhancing interventions based on an individual's symptom presentation.
