Refugees and asylum seekers have often been exposed to multiple or complex traumas and are known to have a high rate of trauma-related disorders. Different therapeutic approaches have been used to treat this group with varying success. Narrative Exposure Therapy (NET) is one promising intervention for refugees and asylum seekers that are suffering from post-traumatic stress-disorder (PTSD). NET is a treatment given individually or in small groups in typically 12 sessions or less. In NET, memories are reorganized through a process involving imaginary exposure to trauma.

To review the literature on NET for refugees and asylum seekers suffering from PTSD.

The data bases PubMed, Medline, PsycInfo and Web of Science were searched using a selection of search terms, including ‘Narrative therapy’, ‘refugees’ and ‘stress disorders, post-traumatic’. The identified relevant articles were qualitatively assessed and effect sizes were compared. Methodological quality was assessed according to the GRADE-criteria.

Thirteen studies were assessed with a total study population of 745. Nine of the included studies were RCTs. Overall, the studies found medium to very high effects of NET. The quality of the studies varied from very low to high. More studies of NET for refugees and asylum seekers are needed, and in particular studies reporting long-term outcomes.

The review suggests that NET shows promise as a method for the treatment of PTSD in refugees and asylum seekers. However, the review is based on relatively few studies and more studies of long-term outcomes are particularly needed.

Interpersonal trauma and post-traumatic stress disorder (PTSD) in patients with severe mental illness (SMI) negatively affect illness course. Narrative exposure therapy (NET) is effective in vulnerable patient groups, but its efficacy and applicability has not been studied in out-patients with SMI.

We aimed to evaluate the efficacy and applicability of NET in SMI on changes in PTSD, dissociation, SMI symptoms, care needs, quality of life, global functioning and care consumption.

The study had a single-group, pre-test–post-test, repeated-measures design and was registered in The Netherlands National Trial Register (identifier TR571). Primary outcomes were assessed at pre-treatment (T0), 1 month post-treatment (T1) and 7 months’ follow-up (T2), with a structured interview for PTSD and dissociation screening. Secondary outcomes followed routinely SMI measurements and medical data. Mixed models were used for data analysis.

The majority of the 23 participants was female (82%). Mean age was 49.9 years (s.d. 9.8) and mean PTSD duration was 24.1 years (s.d. 14.5). Mean PTSD severity decreased from 37.9 at T0 to 31.9 at T1 (−6.0 difference, 95%CI −10.0 to −2.0), and decreased further to 24.5 at T2 (−13.4 difference, 95%CI −17.4 to −9.4). Dissociation, SMI symptoms, duration of contacts, and medication decreased; global functioning increased; and quality of life and perceived needs did not change. Eleven participants were in remission for PTSD at T2, of which five were also in remission for major depression.

NET appeared efficacious and applicable to out-patients with SMI and PTSD, and was well tolerated.

Evidence-based treatment and age-specific services are required to address the needs of trauma-affected older populations. Narrative exposure therapy (NET) may present an appropriate treatment approach for this population since it provides prolonged exposure in a lifespan perspective. As yet, however, no trial on this intervention has been conducted with older adults from Western Europe.

Examining the efficacy of NET in a sample of older adults.

Out-patients with post-traumatic stress disorder (PTSD), aged 55 years and over, were randomly assigned to either 11 sessions of NET (n = 18) or 11 sessions of present-centred therapy (PCT) (n = 15) and assessed on the Clinician-Administered PTSD Scale (CAPS) pre-treatment, post-treatment and at follow-up. Total scores as well as symptom scores (re-experience, avoidance and hyperarousal) were evaluated.

Using a piecewise mixed-effects growth model, at post-treatment a medium between-treatment effect size for CAPS total score (Cohen's d = 0.44) was found, favouring PCT. At follow-up, however, the between-treatment differences were non-significant. Drop-out rates were low (NET 6.7%, PCT 14.3%) and no participant dropped out of the study because of increased distress.

Both NET and PCT appear to be safe and efficacious treatments with older adults: PCT is non-intrusive and NET allows for imaginal exposure in a lifespan perspective. By selectively providing these approaches in clinical practice, patient matching can be optimised.
