Impact and cultural acceptance of the Narrative Exposure Therapy in the aftermath of a natural disaster in Burundi

Barriers and facilitators to the implementation of mental health and psychosocial support programmes following natural disasters in developing countries: A systematic review

Climate change is leading to more frequent and intense natural disasters, with developing countries particularly at risk. However, most research concerning mental health and natural disasters is based in high-income country settings. It is critically important to provide a mental health response to such events, given the negative psychosocial impacts they elicit. The aim of this systematic review is to explore the barriers and facilitators to implementing mental health and psychosocial support (MHPSS) following natural disasters in developing countries. Eight databases were searched for relevant quantitative and qualitative studies from developing countries. Only studies reporting barriers and/or facilitators to delivering MHPSS in response to natural disasters in a low- or middle-income country were included and full texts were critically appraised using the McGill University Mixed Methods Appraisal Tool. Reported barriers and facilitators were extracted and analysed thematically. Thirty-seven studies were included in the review, reflecting a range of natural disaster settings and developing countries. Barriers to implementing MHPSS included cultural relevance, resources for mental health, accessibility, disaster specific factors and mental health stigma. Facilitators identified included social support, cultural relevance and task-sharing approaches. A number of practical approaches can be used to facilitate the implementation of MHPSS in developing country settings. However, more research is needed on MHPSS in the developing country natural disaster context, especially in Africa, and international policies and guidelines need to be re-evaluated using a decolonial lens.

The effects of narrative exposure therapy on COVID-19 patients with post-traumatic stress symptoms: A randomized controlled trial

BACKGROUND

With the global attack of Coronavirus Disease 2019 (COVID-19), cases with Post-traumatic Stress Disorder (PTSD) have been increasing steadily, which seriously affects the quality of life of patients and as such, seeking effective treatments is an urgent matter. Narrative Exposure Therapy (NET) is a typical cognitive behavioral therapy targeting trauma-related psychological disorders and may be an effective intervention.

METHODS

A total of 111 COVID-19 patients near the discharge stage with positive screening results for posttraumatic stress symptoms (PTSS) were randomly assigned (1:1) to either the study group or the control group. The study group received NET and personalized psychological intervention, while the control group only received personalized psychological intervention. PTSS, depression, anxiety and sleep quality were measured pre- and post-intervention to evaluate the effect of NET. This trial was registered with the International Standard Randomized Clinical Trial Registry (No. ChiCTR2000039369).

RESULTS

NET participants showed a significantly greater PTSS reduction in comparison with the control group after the intervention. Improvement in sleep quality, anxiety and depression after the intervention were pronounced but not significantly different between the two treatment groups.

LIMITATIONS

The assessors weren't blinded for the convenience of measurement and protection of participants' psychological security.

CONCLUSIONS

NET likely had a positive impact on PTSS of COVID-19 patients. Clinical staff should consider applying NET to improve the psychological well-being of patients who have experienced an epidemic such as COVID-19.

Strategies for Delivering Mental Health Services in Response to Global Climate Change: A Narrative Review

This narrative review examined strategies for preparedness and response to mental health impacts of three forms of climate change from a services perspective: (1) acute and extreme weather events such as hurricanes, floods, and wildfires, (2) sub-acute or long-term events such as droughts and heatwaves; and (3) the prospect of long-term and permanent changes, including higher temperatures, rising sea levels, and an uninhabitable physical environment. Strategies for acute events included development and implementation of programs and practices for monitoring and treating mental health problems and strengthening individual and community resilience, training of community health workers to deliver services, and conducting inventories of available resources and assessments of at-risk populations. Additional strategies for sub-acute changes included advocacy for mitigation policies and programs and adaptation of guidelines and interventions to address the secondary impacts of sub-acute events, such as threats to livelihood, health and well-being, population displacement, environmental degradation, and civil conflict. Strategies for long-lasting changes included the implementation of evidence-based risk communication interventions that address the existing and potential threat of climate change, promoting the mental health benefits of environmental conservation, and promoting psychological growth and resilience.

Systematic review and meta-analyses of the long-term efficacy of narrative exposure therapy for adults, children and perpetrators

Objective: Narrative Exposure Therapy (NET) is a short-term trauma-focused intervention originally developed for treating survivors of war and torture. The neurobiological theoretical foundations of NET would suggest that the approach should have long term beneficial effects. We tested this assumption and also provided an extensive overview of all NET studies for adults, for children (KIDNET), and for perpetrators (Forensic Offender Rehabilitation NET; FORNET).Method: Following a systematic literature review, we conducted meta-analyses with all studies that had control conditions, and with all Randomized Controlled Trials (RCTs). We assessed between-groups short- (< 6 months) and long-term (≥ 6 months) effect sizes for symptoms of posttraumatic stress disorder (PTSD) and depression.Results: In a total of 56 studies from 30 countries comparing 1370 participants treated with NET to 1055 controls, we found large between group effect sizes regarding the reduction of PTSD symptoms in favor of NET. Analyses of RCTs with active controls yielded small to medium effect sizes in the short-term, and large effect sizes in the long-term.Conclusions: NET, KIDNET, and FORNET yield beneficial and sustainable treatment results for severely traumatized individuals living in adverse circumstances. Studies in highly developed health care systems comparing NET with other evidence-based trauma-focused interventions are needed.

Psychological and social interventions for the prevention of mental disorders in people living in low- and middle-income countries affected by humanitarian crises

BACKGROUND

People living in 'humanitarian settings' in low- and middle-income countries (LMICs) are exposed to a constellation of physical and psychological stressors that make them vulnerable to developing mental disorders. A range of psychological and social interventions have been implemented with the aim to prevent the onset of mental disorders and/or lower psychological distress in populations at risk, and it is not known whether interventions are effective.

OBJECTIVES

To compare the efficacy and acceptability of psychological and social interventions versus control conditions (wait list, treatment as usual, attention placebo, psychological placebo, or no treatment) aimed at preventing the onset of non-psychotic mental disorders in people living in LMICs affected by humanitarian crises.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMD-CTR), the Cochrane Drugs and Alcohol Review Group (CDAG) Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (OVID), Embase (OVID), PsycINFO (OVID), and ProQuest PILOTS database with results incorporated from searches to February 2020. We also searched the World Health Organization's (WHO) International Clinical Trials Registry Platform and ClinicalTrials.gov to identify unpublished or ongoing studies. We checked the reference lists of relevant studies and reviews.

SELECTION CRITERIA

All randomised controlled trials (RCTs) comparing psychological and social interventions versus control conditions to prevent the onset of mental disorders in adults and children living in LMICs affected by humanitarian crises. We excluded studies that enrolled participants based on a positive diagnosis of mental disorder (or based on a proxy of scoring above a cut-off score on a screening measure).

DATA COLLECTION AND ANALYSIS

We calculated standardised mean differences for continuous outcomes and risk ratios for dichotomous data, using a random-effects model. We analysed data at endpoint (zero to four weeks after therapy) and at medium term (one to four months after intervention). No data were available at long term (six months or longer). We used GRADE to assess the quality of evidence.

MAIN RESULTS

In the present review we included seven RCTs with a total of 2398 participants, coming from both children/adolescents (five RCTs), and adults (two RCTs). Together, the seven RCTs compared six different psychosocial interventions against a control comparator (waiting list in all studies). All the interventions were delivered by paraprofessionals and, with the exception of one study, delivered at a group level. None of the included studies provided data on the efficacy of interventions to prevent the onset of mental disorders (incidence). For the primary outcome of acceptability, there may be no evidence of a difference between psychological and social interventions and control at endpoint for children and adolescents (RR 0.93, 95% CI 0.78 to 1.10; 5 studies, 1372 participants; low-quality evidence) or adults (RR 0.96, 95% CI 0.61 to 1.50; 2 studies, 767 participants; very low quality evidence). No information on adverse events related to the interventions was available. For children's and adolescents' secondary outcomes of prevention interventions, there may be no evidence of a difference between psychological and social intervention groups and control groups for reducing PTSD symptoms (standardised mean difference (SMD) -0.16, 95% CI -0.50 to 0.18; 3 studies, 590 participants; very low quality evidence), depressive symptoms (SMD -0.01, 95% CI -0.29 to 0.31; 4 RCTs, 746 participants; very low quality evidence) and anxiety symptoms (SMD 0.11, 95% CI -0.09 to 0.31; 3 studies, 632 participants; very low quality evidence) at study endpoint. In adults' secondary outcomes of prevention interventions, psychological counselling may be effective for reducing depressive symptoms (MD -7.50, 95% CI -9.19 to -5.81; 1 study, 258 participants; very low quality evidence) and anxiety symptoms (MD -6.10, 95% CI -7.57 to -4.63; 1 study, 258 participants; very low quality evidence) at endpoint. No data were available for PTSD symptoms in the adult population. Owing to the small number of RCTs included in the present review, it was not possible to carry out neither sensitivity nor subgroup analyses.

AUTHORS' CONCLUSIONS

Of the seven prevention studies included in this review, none assessed whether prevention interventions reduced the incidence of mental disorders and there may be no evidence for any differences in acceptability. Additionally, for both child and adolescent populations and adult populations, a very small number of RCTs with low quality evidence on the review's secondary outcomes (changes in symptomatology at endpoint) did not suggest any beneficial effect for the studied prevention interventions. Confidence in the findings is hampered by the scarcity of prevention studies eligible for inclusion in the review, by risk of bias in the studies, and by substantial levels of heterogeneity. Moreover, it is possible that random error had a role in distorting results, and that a more thorough picture of the efficacy of prevention interventions will be provided by future studies. For this reason, prevention studies are urgently needed to assess the impact of interventions on the incidence of mental disorders in children and adults, with extended periods of follow-up.

Evaluating narrative exposure therapy for post-traumatic stress disorder and depression symptoms: A meta-analysis of the evidence base

Narrative exposure therapy (NET) is an intervention for trauma spectrum disorders. Originally developed to treat refugee populations, NET has since been tested for efficacy across different settings. In this review, the NET evidence base is examined through a retrieval, synthesis and appraisal of randomized controlled trials (RCTs) published since 2002. Two independent reviewers (S. R. and N. S.) searched online databases including EMBASE, PsycINFO and PubMed. Twenty-four RCTs were selected for a meta-analysis of three outcomes: post-traumatic stress disorder (PTSD) diagnosis and PTSD and depression symptoms. All outcomes were analysed at short-term (3-4 months), midterm (6-7 months) and long-term (≥12 months) data points. A random-effects model was applied to yield standardized mean differences (SMDs) and odds ratios (ORs) as indicators of NET treatment effect. Subgroup analyses for type of trauma and type of control groups were conducted to examine potential heterogeneity. For the NET group, moderate effect sizes for PTSD symptom severity were observed at midterm and long term and at midterm for depression symptom severity. The number of PTSD diagnoses decreased significantly in the short term for the NET condition, but this was not sustained at the long term. Caution must be exercised when interpreting these results due to high heterogeneity estimates and low quality of evidence across trials. Potential small-study effects further complicate the interpretation of the findings. Recommendations are made for augmenting statistical significance research with qualitative analyses of NET efficacy to better inform clinical practice.
