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 p s < .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 p s < .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.
