Narrative Exposure Therapy in Patients With Posttraumatic Stress Disorder and Borderline Personality Disorder in a Naturalistic Residential Setting: A Randomized Controlled Trial

Background: Comorbid Posttraumatic Stress Disorder (PTSD) increases the already high symptom burden of patients with Borderline Personality Disorder (BPD). As the gold standard for BPD treatment, Dialectical Behavior Therapy (DBT), does not focus on PTSD, other treatment approaches are needed. Narrative Exposure Therapy (NET) was designed to address multiple traumatic events and may be especially useful in this patient group. The aim of the present study was to determine the efficacy of NET compared to DBT based treatment (DBT-bt) in a randomized controlled trial.Methods: Female patients (n = 60) with BPD and comorbid PTSD were randomized to either a 10-week residential NET or DBT-bt. The primary outcome was change in PTSD severity as assessed by the Clinician Administered PTSD Scale (CAPS). Mixed linear models as well as reliable change, remission, and response rates were used to compare improvement across treatment groups.Results: Mixed linear model showed that patients in both treatments improved significantly over time across all outcome measures. This improvement was not more pronounced in NET (no significant time × type of treatment effect). However, NET resulted in a higher remission rate as compared to DBT-bt. PTSD remission was accompanied by BPD remission in all cases.Conclusions: This study shows the value of trauma-focused therapy in patients with BPD and PTSD for recovery in both disorders. To shorten the duration of both illnesses as much as possible, future studies should focus on the factors predicting treatment success and enabling patients to benefit from trauma-focused treatment as soon as possible.Trial registration:ClinicalTrials.gov, identifier: NCT02517723.

Feasibility and acceptability of Narrative Exposure Therapy to treat individuals with PTSD who are homeless or vulnerably housed: A pilot randomized controlled trial.

Background: Annually, there are least 235,000 individuals experiencing homelessness in Canada. These individuals are more likely to have complex health issues, including mental health issues such as post-traumatic stress disorder (PTSD). Diagnosed PTSD rates in the homeless are more than double that of the general population, ranging between 21% and 53%. In the homeless population, complex PTSD (cPTSD) appears to be more common than PTSD. One treatment option for cPTSD is Narrative Exposure Therapy (NET), a brief trauma focused psychotherapy which attempts to place the trauma within a narrative of the person's life. Previous studies suggest NET may be an effective option for those who are homeless. In this study, our primary aim was to assess the feasibility and acceptability of delivering community-based NET to individuals with PTSD who were homeless or vulnerably housed. Methods: This pilot randomized controlled trial (RCT) enrolled participants who were 18 years of age or older, currently homeless or vulnerably housed, and with active symptoms of PTSD. Participants were randomized to either NET alone or NET plus the addition of a genealogical assessment. Demographic and clinical data were collected at the baseline visit. Symptoms of PTSD, drug use and housing status were re-assessed at follow-up visits. Rates of referral, consent and retention were also examined as part of feasibility. Results: Twenty-two potential participants were referred to the study. Six were not able to be contacted, one was excluded prior to contact, and the remaining 15 consented to participate. Of these, one was a screen failure and 14 were randomized equally to the treatment arms. One randomized participant was withdrawn for safety. The main point of attrition was prior to starting therapy (3/13). Once therapy was initiated, retention was high with 80% of participants completing all six sessions of therapy. Seven participants completed all follow-up sessions. Conclusion: Delivering NET in a community-based setting and completing genealogical assessments was both feasible and acceptable to those who are homeless or vulnerably housed. Once therapy had been initiated, participants were likely to stay engaged. A large RCT should be conducted to evaluate effectiveness and feasibility on an increased scale.

Narrative exposure therapy for survivors of human trafficking: feasibility randomised controlled trial

Background Human trafficking is a grave human rights violation and a major public health concern. Survivors present with high rates of mental health problems including post-traumatic stress disorder (PTSD). Studies of effective treatments for PTSD in survivors of human trafficking are lacking. Narrative exposure therapy (NET) is an effective PTSD treatment for multiple, prolonged and complex trauma, but its efficacy has not been rigorously tested in survivors of human trafficking. Aims To test the feasibility and acceptability of a randomised controlled trial (RCT) offering NET as a treatment for PTSD in trafficking survivors with a history of multiple traumatic events, as well as providing preliminary evidence regarding its efficacy (trial registration: ISRCTN95136302). Method A single-blind RCT compared NET with a wait-list control in survivors of trafficking with PTSD (n = 25). In the NET arm of the study, participants attended a mean of 17 sessions. Results NET was well tolerated by participants. There were significant reductions in PTSD, depression and anxiety symptoms post-treatment in the NET group but no significant change in the wait-list group. Conclusions The results indicate that NET is a promising and acceptable treatment for trafficking survivors. Psychological therapy in an RCT design can be safely delivered to this vulnerable group, although modifications are required to ensure their holistic needs are properly addressed.

DNA methylation changes following narrative exposure therapy in a randomized controlled trial with female former child soldiers

The aftermath of traumatization lives on in the neural and epigenetic traces creating a momentum of affliction in the psychological and social realm. Can psychotherapy reorganise these memories through changes in DNA methylation signatures? Using a randomised controlled parallel group design, we examined methylome-wide changes in saliva samples of 84 female former child soldiers from Eastern DR Congo before and six months after Narrative Exposure Therapy. Treatment predicted differentially methylated positions (DMPs) related to ALCAM, RIPOR2, AFAP1 and MOCOS. In addition, treatment associations overlapped at gene level with baseline clinical and social outcomes. Treatment related DMPs are involved in memory formation—the key agent in trauma focused treatments—and enriched for molecular pathways commonly affected by trauma related disorders. Results were partially replicated in an independent sample of 53 female former child soldiers from Northern Uganda. Our results suggest a molecular impact of psychological treatment in women with war-related childhood trauma.Trial registration: Addressing Heightened Levels of Aggression in Traumatized Offenders With Psychotherapeutic Means (ClinicalTrials.gov Identifier: NCT02992561, 14/12/2016).

Narrative Exposure Therapy versus treatment as usual in a sample of trauma survivors who live under ongoing threat of violence in Rio de Janeiro, Brazil: study protocol for a randomised controlled trial

Background One in three individuals who live in Rio de Janeiro experience a traumatic event within a period of 12 months. In the favelas particularly, trauma exposure is ongoing. Psychological sequalae include posttraumatic stress disorder (PTSD), depression and other mental disorders. Trauma-focused therapy approaches have emerged as the treatment of choice when the dangerous events are over, but symptoms have remained for an extended time period. Ideally, the victim is in a safe context during treatment. However, frequently, survivors cannot escape from situations characterised by ongoing threat and traumatic stress. The aim of this study is to research the effectiveness of Narrative Exposure Therapy in a sample of PTSD patients living under these conditions. Methods Individuals fulfilling the criteria for PTSD and who live in conditions of ongoing community violence (i.e. in the favelas) in Rio de Janeiro will be randomly assigned to one of two treatments: Narrative Exposure Therapy (NET) or treatment as usual (TAU). Clinical endpoints will be primarily PTSD and secondarily symptoms of shutdown dissociation, depression, substance involvement and functionality. Discussion Effective treatment for PTSD patients who live in unsafe conditions could substantially reduce suffering of individuals and their families in Brazil. Based on this result, the extent to which such interventions may be useful as a first step in tackling the consequences of violence on a global scale will be discussed.
