A Comparison of Narrative Exposure Therapy, Supportive Counseling, and Psychoeducation for Treating Posttraumatic Stress Disorder in an African Refugee Settlement

Little is known about the usefulness of psychotherapeutic approaches for traumatized refugees who continue to live in dangerous conditions. Narrative exposure therapy (NET) is a short-term approach based on cognitive-behavioral therapy and testimony therapy. The efficacy of narrative exposure therapy was evaluated in a randomized controlled trial. Sudanese refugees living in a Ugandan refugee settlement (N = 43) who were diagnosed as suffering from posttraumatic stress disorder (PTSD) either received 4 sessions of NET, 4 sessions of supportive counseling (SC), or psychoeducation (PE) completed in 1 session. One year after treatment, only 29% of the NET participants but 79% of the SC group and 80% of the PE group still fulfilled PTSD criteria. These results indicate that NET is a promising approach for the treatment of PTSD for refugees living in unsafe conditions.

Can Asylum-Seekers with Posttraumatic Stress Disorder Be Successfully Treated? : A Randomized Controlled Pilot Study

Rates of posttraumatic stress disorder (PTSD) are exceptionally high among asylum-seekers. Reportedly, stressors caused by the asylum procedure and psychological consequences of torture contribute to the maintenance of symptoms and interfere with treatment. In a pilot randomized controlled trial, the authors examined the efficacy of trauma-focused treatment in 32 asylum-seekers with PTSD resulting from state-sponsored violence and other traumatic events. Narrative exposure therapy (NET) was compared with treatment as usual (TAU), with a focus on stabilization and psychoactive medication. Six months after treatment, a significant reduction of posttraumatic stress symptoms was found in the NET participants but not in the TAU group. Although treatment gains were moderate, these results indicate that NET is a promising approach for the treatment of PTSD in asylum-seekers living in unstable conditions.

Prävalenz der Posttraumatischen Belastungsstörung (PTSD) und Möglichkeiten der Ermittlung in der Asylverfahrenspraxis

Zusammenfassung. Theoretischer Hintergrund: Posttraumatische Belastungsstorungen (PTSD) spielen in der Asylverfahrenspraxis eine zunehmende Rolle. Dennoch liegen bislang keine Daten zur Pravalenz unter Asylbewerbern in Deutschland vor. Auch ist nicht bekannt, inwieweit Einzelentscheider des Bundesamtes fur die Anerkennung auslandischer Fluchtlinge (BAFl) Anzeichen auf eine Traumatisierung bei der Anhorung erkennen konnen. Fragestellungen: Stellt PTSD eine relevante Grose unter Asylbewerbern in Deutschland dar? Konnen Einzelentscheider mit Hilfe von Kurzinstrumenten Anzeichen auf eine PTSD erkennen? Methode: eigens geschulte Einzelentscheider befragten 76 Asyl-Erstantragsteller mit der eng am DSM-IV orientierten PDS (Posttraumatic Diagnostic Scale). 42 dieser Personen wurden in einem klinisch strukturierten Interview anhand der Sektion N des M-CIDI ausfuhrlich nachuntersucht. Ergebnisse: Bei Asylsuchenden betragt die PTSD-Punkt-Pravalenz ca. 40%. Es ergab sich keine uberzufallige Erkennung dieser psychisch...

Narrative Exposure Therapy for the Treatment of Traumatized Children and Adolescents (KidNET): From Neurocognitive Theory to Field Intervention

Many children in war-affected and refugee populations have experienced multiple traumatic experiences, and high rates of psychologic disorders, especially posttraumatic stress disorder (PTSD), are found. Intervention strategies require pragmatic and effective approaches to treatment. This article describes the rationale for and the use of narrative exposure therapy in children (KidNET). KidNET is a short-term treatment for PTSD based on a neurocognitive theory of traumatic memory. Early treatment trials, including randomized controlled studies, show promising results for the treatment of children and adolescents who have PTSD living in war-affected countries and refugee communities.

A NARRATIVE EXPOSURE TREATMENT AS INTERVENTION IN A REFUGEE CAMP: A CASE REPORT

We applied Narrative Exposure Treatment (NET) to a severely traumatized Kosovar refugee living in a Macedonian refugee camp during the Balkan War. NET is a pragmatic short-term approach that integrates effective therapeutic components deriving from Cognitive Behaviour Therapy and Testimony Therapy. Outcome was evaluated by clinical examination and the Posttraumatic Stress Diagnostic Scale (PDS). Three sessions of NET were enough to afford considerable relief, although some PTSD symptoms remained. Our experience indicates that Narrative Exposure is a promising and realistic approach for the treatment of even severely traumatized refugees living in camps. In addition, it can prove valid testimonies about human rights violations without humiliating the witness.

The Consumption of Khat and Other Drugs in Somali Combatants: A Cross-Sectional Study

Background For more than a decade, most parts of Somalia have not been under the control of any type of government. This “failure of state” is complete in the central and southern regions and most apparent in Mogadishu, which had been for a long period in the hands of warlords deploying their private militias in a battle for resources. In contrast, the northern part of Somalia has had relatively stable control under regional administrations, which are, however, not internationally recognized. The present study provides information about drug abuse among active security personnel and militia with an emphasis on regional differences in relation to the lack of central governmental control—to our knowledge the first account on this topic. Methods and Findings Trained local interviewers conducted a total of 8,723 interviews of armed personnel in seven convenience samples in different regions of Somalia; 587 (6.3%) respondents discontinued the interview and 12 (0.001%) were excluded for other reasons. We assessed basic sociodemographic information, self-reported khat use, and how respondents perceived the use of khat, cannabis (which includes both hashish and marijuana), psychoactive tablets (e.g., benzodiazepines), alcohol, solvents, and hemp seeds in their units. The cautious interpretation of our data suggest that sociodemographic characteristics and drug use among military personnel differ substantially between northern and southern/central Somalia. In total, 36.4% (99% confidence interval [CI] 19.3%–57.7%) of respondents reported khat use in the week before the interview, whereas in some regions of southern/central Somalia khat use, especially excessive use, was reported more frequently. Self-reported khat use differed substantially from the perceived use in units. According to the perception of respondents, the most frequent form of drug use is khat chewing (on average, 70.1% in previous week, 99% CI 63.6%–76.5%), followed by smoking cannabis (10.7%, 99% CI 0%–30.4%), ingesting psychoactive tablets (8.5%, 99% CI 0%–24.4%), drinking alcohol (5.3%, 99% CI 0%–13.8%), inhaling solvents (1.8%, 99% CI 0%–5.1%), and eating hemp seeds (0.6%, 99% CI 0%–2.0%). Perceived use of khat differs little between northern and southern Somalia, but perceived use of other drugs reaches alarmingly high levels in some regions of the south, especially related to smoking cannabis and using psychoactive tablets. Conclusions Our data suggest that drug use has quantitatively and qualitatively changed over the course of conflicts in southern Somalia, as current patterns are in contrast to traditional use. Although future studies using random sampling methods need to confirm our results, we hypothesize that drug-related problems of armed staff and other vulnerable groups in southern Somalia has reached proportions formerly unknown to the country, especially as we believe that any biases in our data would lead to an underestimation of actual drug use. We recommend that future disarmament, demobilization, and reintegration (DDR) programs need to be prepared to deal with significant drug-related problems in Somalia.

Use of khat and posttraumatic stress disorder as risk factors for psychotic symptoms: A study of Somali combatants

The chewing of the khat leaves, which contain the amphetamine-like cathinone, is a traditional habit in Somalia. Our objective was to explore the effects of khat use and Posttraumatic Stress Disorder (PTSD) on paranoid symptoms and to test a potential causal chain. We report on a cross-sectional study in Somalia that was conducted in 2003. Trained local staff interviewed 8723 personnel of armed groups in seven regional convenience samples. Of them, 8124 were included in the analysis. We assessed current khat use, PTSD symptoms, functional drug use and paranoid ideation using items from the Composite International Diagnostic Interview (CIDI) and the Somali version of the Posttraumatic Stress Diagnostic Scale (PDS). Applying the causal steps approach, in a series of logistic regression models, we used PTSD as independent and paranoia as outcome variable; the quantity of khat use was defined as mediator variable and functional drug use as moderator. The results showed that respondents with PTSD used khat more frequently. Khat chewers with PTSD reported a higher intake compared to khat chewers without PTSD. Among excessive khat chewers with PTSD, paranoia was most frequent. The greatest amount of khat use was among respondents with PTSD who indicated that they found drugs help them to forget war experiences. The proposed mediated moderation model was supported by the data, i.e. besides the direct effects of PTSD and functional drug use on paranoia, the amount of khat use appeared to be a mechanism, by which paranoia is caused. We conclude that in our data we have uncovered a relationship between khat, PTSD and paranoia. Khat is functionally used by respondents with PTSD. Findings support a dose effect: the more khat consumption and when a respondent has PTSD, the higher the odds for paranoid ideation. However, the proposed causal chain needs to be confirmed in longitudinal studies. Demobilization and reintegration programs in Somalia need to be prepared to deal with complex psychological problems.

Altered oscillatory brain dynamics after repeated traumatic stress.

BackgroundRepeated traumatic experiences, e.g. torture and war, lead to functional and structural cerebral changes, which should be detectable in cortical dynamics. Abnormal slow waves produced within circumscribed brain regions during a resting state have been associated with lesioned neural circuitry in neurological disorders and more recently also in mental illness.MethodsUsing magnetoencephalographic (MEG-based) source imaging, we mapped abnormal distributions of generators of slow waves in 97 survivors of torture and war with posttraumatic stress disorder (PTSD) in comparison to 97 controls.ResultsPTSD patients showed elevated production of focally generated slow waves (1–4 Hz), particularly in left temporal brain regions, with peak activities in the region of the insula. Furthermore, differential slow wave activity in right frontal areas was found in PTSD patients compared to controls.ConclusionThe insula, as a site of multimodal convergence, could play a key role in understanding the pathophysiology of PTSD, possibly accounting for what has been called posttraumatic alexithymia, i.e., reduced ability to identify, express and regulate emotional responses to reminders of traumatic events. Differences in activity in right frontal areas may indicate a dysfunctional PFC, which may lead to diminished extinction of conditioned fear and reduced inhibition of the amygdala.

Decoupling Neural Networks From Reality Dissociative Experiences in Torture Victims Are Reflected in Abnormal Brain Waves in Left Frontal Cortex

From a neuroscience perspective, little is known about the long-term effect of torture. Dissociative experiences and posttraumatic stress disorder are often the results of this experience. We examined psychological dissociation within a group of 23 torture victims and report its manifestations within neural networks in the human brain. In particular, we observed that dissociative experiences are associated with slow abnormal brain waves generated in left ventrolateral frontal cortex. Given that focal slow waves often result from depriving neural networks of major input, the present results may indicate decoupling of frontal affective processors from left cortical language areas. This interpretation is consistent with the fact that disturbed access to structured verbal memory concerning traumatic events is a core feature of the dissociative experience.
