Narrative exposure therapy for immigrant children traumatized by war: study protocol for a randomized controlled trial of effectiveness and mechanisms of change

The efficacy and acceptability of exposure therapy for the treatment of post-traumatic stress disorder in children and adolescents: a systematic review and meta-analysis

BACKGROUND

Posttraumatic stress disorder (PTSD) is common among children and adolescents who have experienced traumatic events. Exposure therapy (ET) has been shown to be effective in treating PTSD in adults. However, its efficacy remains uncertain in children and adolescents.

AIMS

To evaluate the efficacy and acceptability of ET in children and adolescents with PTSD.

METHOD

We searched PubMed, EMBASE, Cochrane, Web of Science, PsycINFO, CINAHL, ProQuest, LILACS, and international trial registries for randomized controlled trials (RCTs) assessed ET in children and adolescents (aged ≤18 years) with PTSD up to August 31, 2020. The primary outcomes were efficacy (the endpoint score from PTSD symptom severity rating scales) and acceptability (all-cause discontinuation), secondary outcomes included efficacy at follow-up (score from PTSD scales at the longest point of follow-up), depressive symptoms (end-point score on depressive symptom severity rating scales) and quality of life/social functioning (end-point score on quality of life/social functioning rating scales). This study was registered with PROSPERO (CRD42020150859).

RESULT

A total of 6 RCTs (278 patients) were included. The results showed that ET was statistically more efficacious than control groups (standardized mean differences [SMD]: - 0.47, 95% confidence interval [CI]: - 0.91 to - 0.03). In subgroup analysis, exposure therapy was more efficacious for patients with single type of trauma (SMD: - 1.04, 95%CI: - 1.43 to - 0.65). Patients with an average age of 14 years and older, ET was more effective than the control groups (SMD: - 1.04, 95%CI: - 1.43 to - 0.65), and the intervention using prolonged exposure therapy (PE) (SMD: - 1.04, 95%CI: - 1.43 to - 0.65) was superior than control groups. Results for secondary outcomes of efficacy at follow-up (SMD: - 0.64, 95%CI: - 1.17 to - 0.10) and depressive symptoms (SMD: - 0.58, 95%CI: - 0.93 to - 0.22) were similar to the previous findings for efficacy outcome. No statistically significant effects for acceptability and quality of life/social functioning were found.

CONCLUSION

ET showed superiority in efficacy at post-treatment/follow-up and depressive symptoms improvement in children and adolescents with PTSD. Patients with single type of trauma may benefit more from ET. And ET is more effective in patients 14 years or older. Moreover, PE could be a better choice.

Moderating role of moral injury in the mental health of adolescent refugees

OBJECTIVE

This study investigated whether moral injury appraisals moderated the relationships between trauma, postmigration living difficulties, resilience, and mental health outcomes in adolescent refugees.

METHOD

Eighty-five adolescent refugees from a community sample completed an online survey.

RESULTS

A significant interaction was found between moral injury and discrimination for externalizing and posttraumatic stress disorder (PTSD) symptoms; adolescents whom had experienced high levels of discrimination combined with high levels of moral injury had poorer mental health. A significant interaction was found between moral injury and resilience for internalizing symptoms: high levels of resilience appeared to buffer the association between moral injury and internalizing symptoms. Contrary to predictions, stressful life experiences and postmigration living difficulties did not interact significantly with moral injury to predict mental health.

CONCLUSIONS

Discrimination may contribute to perpetuating poor mental health in adolescent refugees with high levels of moral injury. Resilience may buffer some of the negative effects of moral injury.

Resilience and Mental Health Among Syrian Refugee Children in Jordan

Refugee populations are at high risk of experiencing trauma and developing negative mental health outcomes. The resilience of Syrian refugee children is not well established as far as modifying the association between trauma and mental illness. A total of 339 Syrian refugee children aged 10 to 17 were surveyed to assess resilience, depression and history of trauma. All children reported exposure to at least one traumatic event, 48.6% reported exposure to highly salient traumatic events such as being held hostage, kidnapping or imprisonment. High rates of suicidal ideation and depression symptomatology were found. Resilience was strongly inversely related to depression. Relational support was found to be the most protective resilience factor and was the most highly correlated with less depressive symptomatology. Empowering children and families to build resilience through social support may be a viable prevention and management approach to other unaffordable or unavailable treatments for mental illnesses.

Researching the Effectiveness of Tree of Life: an Imbeleko Approach to Counseling Refugee Youth

With the growing worldwide refugee crisis, there is a need for evidence-based interventions that specifically deal with the consequences of cumulative trauma-exposure in refugee youth. Refugee children have unique service needs and differ from their non-refugee peers in terms of sociocultural trauma, language, culture, and educational barriers. This article explains the complexities associated with understanding refugee youth and presents a proposal for studying the possible benefits of Tree of Life therapy. At the present time, Tree of Life therapy has no evidence-base because the published studies of Tree of Life with refugee and/or immigrant youth have sample sizes of one, six, eight, and twenty-nine. As a culturally-grounded, strength-based group counseling approach, Tree of Life therapy addresses traumatic experiences, recognizes participants' cultural differences, highlights individual skills, and aids in instilling both confidence and hope for the future. Ncazelo Ncube, the co-founder and main developer of Tree of Life, describes this therapy as a collective narrative practice that considers cultural beliefs and values (2006, 2010, 2018, 2019). The proposed research design is to study the effectiveness of the Tree of Life in Canada, the United States, the United Kingdom, and South Africa. The research plan is to use pragmatic, group-randomized controlled trials in the "real world" settings of schools and agencies in each of the four countries. In addition, the article describes the development of the Roots and Wings Questionnaire for Children and Youth, a culturally relevant, child-friendly questionnaire. The Tree of Life is a readily available therapy with great potential for helping traumatized refugee youth as well as other trauma-impacted young people worldwide.

Changes in Traumatic Memories and Posttraumatic Cognitions Associate with PTSD Symptom Improvement in Treatment of Multiply Traumatized Children and Adolescents

Refinement, targeting, and better dissemination of trauma-focused therapies requires understanding their underlying mechanisms of change. Research on such mechanisms among multiply traumatized children and adolescents is scarce. We examined the role of improvements in problematic qualities of traumatic memories and maladaptive posttraumatic cognitions in PTSD symptom reduction, in a randomized, pragmatic trial of narrative exposure therapy vs. treatment as usual with 40 participants 9-17 years old (48% female, 75% refugee background) repeatedly exposed to war or family violence related trauma. Posttraumatic cognitions, quality of traumatic memories and PTSD symptoms were assessed by self-report before and after treatment. Improvements in both quality of traumatic memories (r _MI = .36) and posttraumatic cognitions (r _MI = .46) correlated with symptom reduction. However, improvement during treatment was only significant for quality of traumatic memories (F _MI(11,333.56) = 4.77), not for posttraumatic cognitions. We detected no difference in effects of narrative exposure therapy and treatment as usual on cognitions or memories. We tentatively suggest problematic, overly sensory and incoherent quality of traumatic memories may be a useful target in the treatment of PTSD symptoms among multiply traumatized children and adolescents. Changing maladaptive posttraumatic cognitions, though important, may be challenging among those with severe, repeated trauma.

A Comparison of Narrative Exposure Therapy and Non-Trauma-Focused Treatment in Post-Traumatic Stress Disorder: A Systematic Review and Meta-Analysis

Background: Narrative Exposure Therapy (NET) is a relatively new treatment that may be beneficial as a standalone approach or as an adjunct for use in individuals who suffer from simple or complex Posttraumatic Stress Disorder (PTSD).Aims: The main objective of this review was to explore the effectiveness of NET in remediating PTSD symptoms as compared to Non Trauma-Focused-Therapy (NTFT).Methods: A systematic search in Medline, PsycINFO, EMBASE and The Cochrane Central Register of Controlled Trials (CENTRAL) was carried out. Reference lists of papers and grey literature were hand searched. Experimental studies that compare NET to NTFT with no preference to age, gender or nationality of participants that include a baseline and 3-6 month measurement of PTSD outcomes using tools with good psychometric properties were included. The search resulted in 10 randomised controlled trials. Data extraction, collection and analysis was then carried out by the authors.Results: In all of the studies, the difference in the PTSD symptoms' mean score after 3-6 months between the NET group and the NTFT group was in favour of NET. However, the level of significance was attained in six of the studies only. The overall effect size (standardised mean difference) of the trials is 0.684 in favour of NET (p < .001).Conclusions: NET was shown to be superior to NTFT in post-traumatic stress disorder. The most important recommendations are in relation to research and target the methodological limitations of existing studies in particular the small sample sizes, lack of blindness and inadequate rigour during the trials. More research is needed to further explore the benefits of NET for different populations and trauma-types.

Reconstructing Personal Stories in Virtual Reality sas a Mechanism to Recover the Self

Advances in virtual reality present opportunities to relive experiences in an immersive medium that can change the way we perceive our life stories, potentially shaping our realities for the better. This paper studies the role of virtual reality as a tool for the creation of stories with the concept of the self as a narrator and the life of the self as a storyline. The basis of the study is the philosophical notion of the self-narrative as an explanatory story of the events in one’s life that constitutes the notion of one’s self. This application is suitable for cases when individuals need to recreate their self, such as during recovery after traumatic events. The analysis of the effects of virtual reality shows that it enables a person to engage in a process of deeper self-observation to understand and explain adverse events and to give meaning to these events to form a new story, which can complement the therapeutic outcomes of exposure treatments. This study proposes concrete examples of immersive scenarios used to reconstruct personal stories. Several possible levels of experience are proposed to suggest that recovery can be achieved through the gradual retelling of the self-narrative, addressing all of the underlying narratives. Considering the ethical challenges that might arise, this paper explores the ways in which immersion in virtual reality can benefit a person’s view toward life as a story and his or her self as its author, comparing this idea with previous research on the application of virtual reality for trauma treatment. The analysis also emphasizes the perception of narrative authorship in virtual reality as an essential method for recovering the self-narrative and improving a patient’s mental health during self-actualization.

Practitioner Review: Mental health problems of refugee children and adolescents and their management

BACKGROUND

Since 2010, the numbers of refugees have increased and around half are under 18 years of age. It is known that experience of organised violence, displacement and resettlement increases the risk for psychiatric disorders and psychosocial impairment. This review integrates recent research into the risk and protective factors for psychopathology with service and treatment issues.

METHODS

We draw on and critically evaluate key systematic reviews in the selected areas, innovative robust studies and relevant government reports.

RESULTS

Many refugee children show resilience and function well, even in the face of substantial adversities. The most robust findings for psychopathology are that PTSD, and posttraumatic and depressive symptoms are found at higher prevalence in those who have been exposed to war experiences. Their severity may decrease over time with resettlement, but PTSD in the most exposed may show higher continuity. More severe psychiatric disorders including psychosis may also occur. Service delivery needs to take into account socioeconomic and cultural influences but, given the high level of unmet need even in high-income countries, stepped care delivery is required. The evaluation of psychological interventions, often delivered in group settings, suggests that they can be effective for many distressed children; however, for the more impaired, a greater range of disorder-specific therapies will be required.

CONCLUSIONS

Child and adolescent mental health clinicians and service providers need to be aware of the specific needs of this population and systems for service delivery. There are significant knowledge gaps in understanding risk and vulnerability, service delivery and treatment effectiveness.

Treating children and adolescents with multiple traumas: a randomized clinical trial of narrative exposure therapy

Background and Objective: Millions of children and adolescents worldwide suffer from post-traumatic stress disorder (PTSD) and other problems due to prolonged exposure to traumatizing events. Forms of cognitive-behavioural therapy are the most commonly used treatment for PTSD, but evidence from sophisticated studies in clinical settings among children is limited. Method: This multicentre, parallel, non-blinded, pragmatic randomized controlled trial assessed the effectiveness of narrative exposure therapy (NET) in traumatized children and adolescents. Fifty 9-17-year-old participants, who had experienced prolonged traumatic conditions in the form of refugeedom or family violence and suffered from PTSD symptoms, were randomized into NET (n = 29) and treatment as usual (TAU; n = 21) active control groups. The objective was to determine whether NET can be feasibly implemented within the existing healthcare system of a high-income country and whether it would reduce mental health problems, especially PTSD, and increase resilience, in children and adolescents with multiple traumas more effectively than TAU. We hypothesized that NET would be more effective than TAU in reducing symptoms and increasing resilience. Results: Analysis of variance revealed that PTSD and psychological distress, but not depression symptoms, decreased regardless of treatment group. Resilience increased in both groups. Within-group analyses showed that the decrease in PTSD symptoms was significant in the NET group only. The effect sizes were large in NET but small in TAU. Concerning PTSD symptom cut-off scores, the reduction in the share of participants with clinical-level PTSD was significant in the NET group only. Intention-to-treat analyses using linear mixed models confirmed these results. Conclusions: Despite its shortcomings, this study gives preliminary support for the safety, effectiveness, and usefulness of NET among multiply traumatized children and adolescents in clinical settings. Close attention must be paid to the implementation of the new intervention as an everyday tool in healthcare.

A comparative study of psychotic and affective symptoms in Rwandan and Kenyan students

AIMS

War and conflict are known to adversely affect mental health, although their effects on risk symptoms for psychosis development in youth in various parts of the world are unclear. The Rwandan genocide of 1994 and Civil War had widespread effects on the population. Despite this, there has been no significant research on psychosis risk in Rwanda. Our goal in the present study was to investigate the potential effects of genocide and war in two ways: by comparing Rwandan youth born before and after the genocide; and by comparing Rwandan and Kenyan adolescents of similar age.

METHODS

A total of 2255 Rwandan students and 2800 Kenyan students were administered the Washington Early Recognition Center Affectivity and Psychosis (WERCAP) Screen. Prevalence, frequency and functional impairment related to affective and psychosis-risk symptoms were compared across groups using univariate and multivariate statistics.

RESULTS

Rwandan students born before the end of the genocide and war in 1994 experienced higher psychotic and affective symptom load (p's < 0.001) with more functional impairment compared with younger Rwandans. 5.35% of older Rwandan students met threshold for clinical high-risk of psychosis by the WERCAP Screen compared with 3.19% of younger Rwandans (χ 2 = 5.36; p = 0.02). Symptom severity comparisons showed significant (p < 0.001) group effects between Rwandan and Kenyan secondary school students on affective and psychotic symptom domains with Rwandans having higher symptom burden compared with Kenyans. Rwandan female students also had higher rates of psychotic symptoms compared with their male counterparts - a unique finding not observed in the Kenyan sample.

CONCLUSIONS

These results suggest extreme conflict and disruption to country from genocide and war can influence the presence and severity of psychopathology in youth decades after initial traumatic events.

Resilience in Context: A Brief and Culturally Grounded Measure for Syrian Refugee and Jordanian Host-Community Adolescents

Validated measures are needed for assessing resilience in conflict settings. An Arabic version of the Child and Youth Resilience Measure (CYRM) was developed and tested in Jordan. Following qualitative work, surveys were implemented with male/female, refugee/nonrefugee samples (N = 603, 11–18 years). Confirmatory factor analyses tested three‐factor structures for 28‐ and 12‐item CYRMs and measurement equivalence across groups. CYRM‐12 showed measurement reliability and face, content, construct (comparative fit index = .92–.98), and convergent validity. Gender‐differentiated item loadings reflected resource access and social responsibilities. Resilience scores were inversely associated with mental health symptoms, and for Syrian refugees were unrelated to lifetime trauma exposure. In assessing individual, family, and community‐level dimensions of resilience, the CYRM is a useful measure for research and practice with refugee and host‐community youth.
