Choosing the right track: improving PTSD treatment outcomes for patients with childhood abuse-related posttraumatic stress disorder

Physical and sexual abuse during childhood can have long lasting consequences such as posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) is an established and effective guideline treatment for PTSD. Nevertheless, a considerable number of patients drop out from treatment or do not (completely) recover from PTSD during PE. It has been suggested that patients with PTSD resulting from childhood abuse are specifically at risk for suboptimal treatment outcomes. We carried out a randomized controlled trial with 149 patients with childhood abuse-related PTSD comparing PE with two innovations: intensified PE (iPE) and skills training in affective and interpersonal regulation followed by PE (STAIR+PE). We found that all treatments were safe and resulted in large improvements in PTSD symptoms. iPE and STAIR+PE did not improve treatment outcomes of PE, although iPE led to faster symptom improvements. Not all patients benefitted from the allocated treatment, but we found no contra-indications for the treatments. We found that a combination of patient characteristics was predictive of a larger effect size of PTSD symptom improvement in PE and iPE or STAIR+PE. We conclude that the three forms of exposure therapy were effective treatments for patients with childhood abuse-related PTSD.This research was supported by grants from ZonMW (DoelmatigheidsOnderzoek #843001705) and Innovatiefonds Zorgverzekeraars (#3.180).

Does complex PTSD predict or moderate treatment outcomes of three variants of exposure therapy?

Background: One reason for the inclusion of Complex Posttraumatic Stress Disorder (CPTSD) in the 11th revision of the International Classification of Diseases (ICD-11) was its suspected relevance for treatment indications. We investigated whether CPTSD predicted and moderated treatment outcomes of Prolonged Exposure (PE), intensified PE (iPE) and Skills Training in Affective and Interpersonal Regulation followed by PE (STAIR + PE). We expected that CPTSD would predict worse treatment outcomes across treatments. Secondly, we expected that CPTSD would lead to better treatment effect in STAIR + PE compared to PE and iPE.Methods: We analyzed 149 patients with childhood-abuse related PTSD from a randomized clinical trial. CPTSD diagnosis and symptom severity were measured with the International Trauma Questionnaire. The main outcome was change in clinician-assessed PTSD symptoms. Assessments took place at baseline, week 4, week 8, week 16 (post-treatment) and at a 6-and 12-month follow-up. Analyses were based on an intention-to-treat sample using mixed effect models.Results: More than half (54 %) of the patients met criteria for CPTSD at baseline. CPTSD was related to more severe PTSD symptoms and higher comorbidity at baseline. CPTSD neither predicted nor moderated treatment outcome. Limitations: Inclusion was limited to patients with PTSD related to childhood abuse. Replication is needed in different samples.Conclusions: CPTSD is associated with more severe PTSD and with higher comorbidity. CPTSD did not predict treatment outcome and did not indicate differential treatment outcome of STAIR + PE compared to PE and iPE.Stress-related psychiatric disorders across the life spa

The relationship between tonic immobility and the development, severity, and course of posttraumatic stress disorder: Systematic and meta-analytic literature review

Background: Tonic immobility (TI) is a reflexive, involuntary response that causes motor inhibition, vocal suppression, and analgesia. TI is elicited by extreme fear and perception of entrapment in a life-threatening situation. Research suggests that TI is a frequent peritraumatic response and may be related to subsequent posttraumatic stress disorder (PTSD). However, findings are mixed and, as of yet, no systematic or meta-analytic review examining associations between TI and PTSD has been published. Objective: We systematically and meta-analytically reviewed the literature and investigated whether TI is associated with the development, severity, and course of PTSD. Additionally, we evaluated whether different types of traumatic events are differentially associated with TI, and whether TI severity differs according to sex. Methods: A systematic literature search was conducted using Embase, PubMed, PsycINFO, and Scopus. Meta-analyses were performed on the included articles. Results: We identified 27 eligible articles. We found a significant association between TI and PTSD symptom severity (r = 0.39, 95% CI: 0.34–0.44; p <.0001). TI was more severe among females (Cohen's d=0.37, 95% CI: 0.25–0.48; p <.0001) and was more often elicited in situations involving interpersonal violence. We found limited longitudinal data to perform a meta-analysis of the association between TI and the development and/or course of PTSD. However, the literature available seems to support the role of TI in both the development and course of PTSD. Conclusions: Peritraumatic TI is associated with PTSD symptom severity, occurs more often during interpersonal violence, and is more severe among females. More longitudinal research is needed to investigate the role of TI in psychopathology development and course
