Community-Based Interventions for the Treatment and Management of Conflict-Related Trauma in Low-Middle Income, Conflict-Affected Countries: a Realist Review

Post-traumatic stress disorder: evolving conceptualization and evidence, and future research directions

The understanding of responses to traumatic events has been greatly influenced by the introduction of the diagnosis of post-traumatic stress disorder (PTSD). In this paper we review the initial versions of the diagnostic criteria for this condition and the associated epidemiological findings, including sociocultural differences. We consider evidence for post-traumatic reactions occurring in multiple contexts not previously defined as traumatic, and the implications that these observations have for the diagnosis. More recent developments such as the DSM-5 dissociative subtype and the ICD-11 diagnosis of complex PTSD are reviewed, adding to evidence that there are several distinct PTSD phenotypes. We describe the psychological foundations of PTSD, involving disturbances to memory as well as to identity. A broader focus on identity may be able to accommodate group and communal influences on the experience of trauma and PTSD, as well as the impact of resource loss. We then summarize current evidence concerning the biological foundations of PTSD, with a particular focus on genetic and neuroimaging studies. Whereas progress in prevention has been disappointing, there is now an extensive evidence supporting the efficacy of a variety of psychological treatments for established PTSD, including trauma-focused interventions - such as trauma-focused cognitive behavior therapy (TF-CBT) and eye movement desensitization and reprocessing (EMDR) - and non-trauma-focused therapies, which also include some emerging identity-based approaches such as present-centered and compassion-focused therapies. Additionally, there are promising interventions that are neither psychological nor pharmacological, or that combine a pharmacological and a psychological approach, such as 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy. We review advances in the priority areas of adapting interventions in resource-limited settings and across cultural contexts, and of community-based approaches. We conclude by identifying future directions for work on trauma and mental health.

Community-informed perspectives of implementing interpersonal psychotherapy for couples to reduce situational intimate partner violence and improve common mental disorders in Mozambique

Background

High rates of intimate partner violence (IPV) and mental disorders are present in Mozambique where there is a significant treatment gap. We aimed to report Mozambican community stakeholder perspectives of implementing couple-based interpersonal psychotherapy (IPT-C) in preparation for a pilot trial in Nampula City.

Methods

We conducted 11 focus group discussions (6-8 people per group) and seven in-depth interviews with key informants in mental health or gender-based violence (n = 85) using purposive sampling. We used grounded theory methods to conduct an inductive coding and then deductively applied the consolidated framework for implementation research (CFIR).

Results

For the outer setting, local attitudes that stigmatize mental health conditions and norm IPV as well as an inefficient legal system were barriers. Stakeholders expressed high acceptability of IPT-C, although a lack of resources was a structural challenge for the inner setting. Adaptation of the approach to screen for and address potential mediators of IPV was important for adopting a multisectoral response to implementation and planning. Delivering IPT-C in the community and in collaboration with community stakeholders was preferable.

Conclusion

Stakeholders recommended multilevel involvement and inclusion of community-based programming. Task shifting and use of technology can help address these resource demands.

Interventions targeting social determinants of mental disorders and the Sustainable Development Goals: a systematic review of reviews

Globally, mental disorders account for almost 20% of disease burden and there is growing evidence that mental disorders are socially determined. Tackling the United Nations Sustainable Development Goals (UN SDGs), which address social determinants of mental disorders, may be an effective way to reduce the global burden of mental disorders. We conducted a systematic review of reviews to examine the evidence base for interventions that map onto the UN SDGs and seek to improve mental health through targeting known social determinants of mental disorders. We included 101 reviews in the final review, covering demographic, economic, environmental events, neighborhood, and sociocultural domains. This review presents interventions with the strongest evidence base for the prevention of mental disorders and highlights synergies where addressing the UN SDGs can be beneficial for mental health.

'Madness' after the war in Bosnia and Herzegovina - challenging dominant understandings of distress

This article reports on the findings from a small-scale co-produced qualitative study on experiences of distress caused by the war in Bosnia and Herzegovina (BiH). Inspired by the emerging interdisciplinary field of Mad Studies, the study is novel and unique in two ways. First, it prioritises social understanding and interpretation of madness and distress. Second, an emphasis is placed on experiential knowledge. Beyond interviews with 20 people who experienced distress due to political conflict, this included contextualisation of the study in the knowledge generated through survivor research and within the field of Mad Studies. Study findings highlight the social causes and consequences of distress caused by conflict, such as war-related violence, gender-based violence, experiences of poverty and corruption. Participants stressed the importance of safety and support within their own home, mutual and supportive relationships with their families, friends, other people who experienced distress, the broader community and opportunities to do everyday activities they enjoy. In terms of professional support, the findings suggest that poverty alleviation and protection of people's right to self-determination through access to human rights advocacy and representation may be as relevant as non-coercive community-based services. This indicates that support for distress caused by political conflict need not be different from any other support for people who experience distress. Emphasis should be placed on survivor-run initiatives and non-coercive, community-based support which addresses social causes of distress and enables people to exercise self-determination.

Barriers and Facilitators to Implementing a Community-Based Psychosocial Support Intervention Conducted In-Person and Remotely: A Qualitative Study in Quibdó, Colombia

Community-based psychosocial support group (CB-PSS) interventions using task-shifting approaches are well suited to provide culturally appropriate services in low- and middle-income countries. However, contextual barriers and facilitators must be considered to tailor interventions effectively, particularly considering the challenges introduced by the COVID-19 pandemic. We explore the barriers, facilitators, and psychosocial changes associated with implementing a CB-PSS group intervention delivered by local lay providers to conflict-affected adults in Quibdó, Colombia, using both in-person and remote modalities. Data were analyzed from 25 individual interviews with participants and a focus group discussion involving staff members, including 7 community psychosocial agent facilitators and 2 mental health professional supervisors. The analysis used a thematic approach grounded in a descriptive phenomenology to explore the lived experiences of participants and staff members during implementation. Participant attendance in the in-person modality was compromised by factors such as competing work and family responsibilities and disruption caused by the COVID-19 pandemic. Participants in the remote modality faced challenges concerning unstable Internet connectivity, recurrent power outages caused by heavy rain, distractions, interruptions, and threats to confidentiality by family and coworkers. Despite these challenges, data revealed key contextual facilitators, including the community-based knowledge of facilitators and integration of traditional practices, such as the comadreo (informal talks and gatherings). Respondents shared that the CB-PSS groups promoted stronger community relationships and created opportunities for participants to exchange peer support, practice leadership skills, develop problem-solving skills based on peers' experiences, and enhance emotional regulation skills. Differences and similarities across in-person and remote modalities are discussed, as are key considerations for practitioners and policymakers.

Improving Traumatic Stress with Justice-Impacted Women and Women Experiencing Homelessness: A Pilot Study of Narrative Exposure Therapy

OBJECTIVE

We sought to investigate the feasibility, acceptability, and impact of a brief, manualized trauma-focused intervention aimed at improving PTSD symptoms in persons with complex PTSD, Narrative Exposure Therapy (NET).

DESIGN

Using a mixed methods approach, we tested the feasibility, acceptability, and impact of NET in a sample of trauma-affected women in traumatogenic circumstances: justice-impacted women in prison and women experiencing homelessness in a shelter. We quantitatively assessed data using a single sample, pre-/post-intervention design. We qualitatively assessed self-described symptom change and opportunities for intervention adaptation using a content analysis approach.

METHODS

Sixteen trauma-affected participants completed the intervention protocol. NET interventionists included one nurse practitioner, one registered nurse, and one nursing student. All NET participants attended pre-/post-intervention visits and active NET sessions. In-depth interviews were conducted at pre- and post-intervention, alongside a diagnostic battery.

RESULTS

NET was both highly feasible and acceptable among participants. Participants significantly improved on the intervention-specific outcome of PTSD symptoms, as well as somatic symptom burden, with large effect sizes. Participants also improved on subjective self-described symptom change. Participants offered recommendations regarding opportunities to enhance population-specific intervention acceptability.

CONCLUSIONS

Results from this pilot study are consistent with previous evidence demonstrating that NET facilitates improvements in women with traumatic stress. Findings of high feasibility, acceptability, and impact supports the use of NET in JW and WEH. Integrating participant recommendations to optimize acceptability may further support scalability and reach of NET. Replication with a larger sample and within a randomized controlled design is required to definitively determine effectiveness.

Making an economic argument for investment in global mental health: The case of conflict-affected refugees and displaced people

Mental health expenditure accounts for just 2.1% of total domestic governmental health expenditure per capita. There is an economic, as well as moral, imperative to invest more in mental health given the long-term adverse impacts of mental disorders. This paper focuses on how economic evidence can be used to support the case for action on global mental health, focusing on refugees and people displaced due to conflict. Refugees present almost unique challenges as some policy makers may be reluctant to divert scarce resources away from the domestic population to these population groups. A rapid systematic scoping review was also undertaken to identify economic evaluations of mental health-related interventions for refugees and displaced people and to look at how this evidence base can be strengthened. Only 11 economic evaluations focused on the mental health of refugees, asylum seekers and other displaced people were identified. All but two of these intervention studies potentially could be cost-effective, but only five studies reported cost per quality-adjusted life year gained, a metric allowing the economic case for investment in refugee mental health to be compared with any other health-focused intervention. There is a need for more consistent collection of data on quality of life and the longer-term impacts of intervention. The perspective adopted in economic evaluations may also need broadening to include intersectoral benefits beyond health, as well as identifying complementary benefits to host communities. More use can be also made of modelling, drawing on existing evidence on the effectiveness and resource requirements of interventions delivered in comparable settings to expand the current evidence base. The budgetary impact of any proposed strategy should be considered; modelling could also be used to look at how implementation might be adapted to contain costs and take account of local contextual factors.
