A Full Systematic Review on the Effects of Cognitive Behavioural Therapy for Mental Health Symptoms in Child Refugees

Brief CBT-based psychological interventions to improve mental health outcomes in refugee populations: a systematic review and meta-analysis

Background: Refugees, asylum seekers, and internally displaced people experience a high burden of mental health problems owing to their experiencing traumas and stressful events.Objective: To summarise the available evidence and analyse the efficacy of brief psychological interventions (< 3 months) on improving mental health outcomes, including depression, anxiety, and post-traumatic stress disorder (PTSD)-related symptoms in refugees.Method: We searched Medline, EMBASE, PsycINFO, CINAHL, and Global Index Medicus from inception to 19 December 2023. We included controlled studies using any cognitive behavioural therapy (CBT) or CBT-based therapies delivered over a short time (< 3 months), which reported mental health outcomes pre-and post-intervention. We conducted meta-analyses using random effects to derive pooled summary statistics. The quality of the evidence was assessed with the Cochrane Risk of Bias (RoB2) and ROBINS-I tools. This study is registered on the Open Science Framework, DOI 10.17605/OSF.IO/9CXU4.Results: 34 eligible studies across 37 publications were retrieved for analysis, and 33 studies with 4479 participants were included in the meta-analysis. There was an overall improvement in immediate mental health outcomes for all three domains, with analysis of 13 studies on anxiety outcomes (SMD -1.12, 95% CI -1.72 to -0.52), 20 studies on depression (SMD -1.04, 95% CI -1.97 to -0.11), and 24 studies on PTSD (SMD -0.82, 95% CI -1.20 to -0.45). At 3 to 6-month follow-up, however, analysis of mental health outcomes shows no significant change from baseline, with a SMD of 0.24 (95% CI -0.94 to 1.42) across 4 studies, -0.73 (95% CI -2.14 to 0.68) across 9 studies, and 0.29 (95% CI -0.94 to 1.53) across 12 studies for anxiety, depression, and PTSD respectively.Conclusion: Low-quality evidence shows brief psychological interventions have a positive immediate effect on refugees and internally displaced people's mental well-being. However, these effects do not persist in the short-term follow up. Heterogeneity was high, even among subgroups, impacting our findings' generalisability.

Examining cognitive behavioral therapy interventions for unaccompanied minors: a systematic review and qualitative research synthesis

BACKGROUND

This systematic review examined the evidence on effectiveness and acceptability of cognitive behavioral therapy (CBT) interventions in improving quality of life (QoL) and psychological well-being of unaccompanied minors (UM).

METHODS

PubMed, Scopus, Embase, ProQuest, PsycInfo, PsycArticles, and Open Dissertations databases were used to identify quantitative and qualitative studies. The Effective Public Health Practice Project (EPHPP) and Critical Appraisal Skills Programme (CASP) tools were used for quality assessment. Narrative synthesis and qualitative research synthesis were carried out to collate the findings.

RESULTS

18 studies were included. Two studies examined QoL, and five studies examined acceptability of interventions. Most quantitative studies (n = 10) were appraised as methodologically weak. Trauma-Focused CBT appears to have the most evidence demonstrating effectiveness in ameliorating symptoms of post-traumatic stress disorder, depression, and anxiety. Promising findings (i.e., increased mindfulness and psychological flexibility) were observed for third wave interventions but further replication is required.

CONCLUSIONS

The literature is tainted by under-powered studies, lacking blinding, and follow-up assessments. Female UM remain largely underrepresented. This review calls for a drastic augmentation of high quality quantitative and qualitative research focusing on augmenting QoL and examining acceptability rather than merely aiming for psychological symptom reduction in UM to enhance overall well-being and functionality. The research protocol was registered in PROSPERO (registration number: CRD42021293881).

Children Fleeing War-Exploring the Mental Health of Refugee Children Arriving in Israel after the Ukraine 2022 Conflict

BACKGROUND

In February 2022, Ukraine suffered a devastating assault by Russia, leading to destruction, casualties, and mass displacement. Among those displaced were over 1.5 million children. Forced displacement exposes children to a heightened risk of mental health issues.

OBJECTIVE

This study investigated the prevalence of Post-traumatic stress disorder (PTSD) and other mental health issues among child refugees shortly after their displacement from Ukraine to Israel. It aimed to identify factors influencing PTSD development and explore their associations.

METHODS

The study included 59 child refugees who had arrived in Israel after fleeing the war in Ukraine. Parents completed self-report questionnaires to assess their children's mental health.

RESULTS

Only three children met the DSM diagnostic criteria for PTSD, with higher scores in the negative cognition and re-experiencing clusters. Over half of the children exhibited general mental health problems, with approximately 40 % showing internalizing problems, and 30 % showing externalizing problems. The study also found a significant comorbidity between PTSD symptoms and internalizing problems. Additionally, internalizing problems emerged as the sole significant predictor of PTSD levels when considering factors such as age, gender, economic status, parents' work status, internalizing problems, and externalizing problems.

CONCLUSIONS

Child refugees frequently experience psychological distress, even if they do not meet the formal diagnostic criteria for PTSD. They often exhibit other distress symptoms, primarily internalizing problems, which can be challenging to detect. A deeper understanding of the challenges faced by refugee children can inform the development of targeted assistance programs and the recruitment and training of personnel in host countries.

Interventions to enhance psychological resilience in forcibly displaced children: a systematic review

BACKGROUND

Children represent nearly 40% of forcibly displaced populations and are subject to stressors that affect well-being. Little is known about the effects of interventions to enhance psychological resilience in these children, outside clinical settings.

METHODS

We conducted a systematic review, following Cochrane methods. Eligible studies tested resilience-enhancing interventions outside clinical settings in forcibly displaced children/adolescents. We included longitudinal quantitative studies with comparator conditions irrespective of geographical scope or language. We searched articles published between January 2010 and April 2020 in PubMed, Embase, Cochrane Library, Web of Science, PsycINFO and the WHO's Global Index Medicus. To standardise effect sizes across the different reported outcomes, we transformed reported mean differences to standardised mean differences using Hedge's g statistic with associated 95% CI. We pooled data for meta-analysis where appropriate. We used Cochrane tools to assess study risk of bias and used Grading of Recommendations Assessment, Development and Evaluation to determine evidence quality for meta-analysed outcomes.

RESULTS

Searches yielded 4829 results. Twenty-three studies met inclusion criteria. Studies reported 18 outcomes measured by 48 different scales; only 1 study explicitly measured resilience. Eight studies were randomised controlled trials; the rest were non-randomised pre-post studies. Interventions were diverse and typically implemented in group settings. Studies reported significant improvement in outcomes pertinent to behavioural problems, coping mechanisms and general well-being but not to caregiver support or psychiatric symptoms. In meta-analysis, resilience was improved (g_av=0.194, 95% CI 0.018 to 0.369), but anxiety symptoms and quality of life were not (g_av=-0.326, 95% CI -0.782 to 0.131 and g_av=0.325, 95% CI -0.027 to 0.678, respectively). Risk of bias varied. Quality of evidence for most graded outcomes was very low.

CONCLUSIONS

The multiplicity of study designs, intervention types, outcomes and measures incumbered quantifying intervention effectiveness. Future resilience research in this population should use rigorous methods and follow reporting guidelines.

Critical life course interventions for children and adolescents to promote mental health

Childhood and adolescence are key developmental periods in the life course for addressing mental health, and there is ample evidence to support significant, increased investment in mental health promotion for this group. However, there are gaps in evidence to inform how best to implement mental health promotion interventions at scale. In this review, we examined psychosocial interventions implemented with children (aged 5–10 years) and adolescents (aged 10–19 years), drawing on evidence from WHO guidelines. Most psychosocial interventions promoting mental health have been implemented in school settings, with some in family and community settings, by a range of delivery personnel. Mental health promotion interventions for younger ages have prioritised key social and emotional skills development, including self-regulation and coping; for older ages, additional skills include problem-solving and interpersonal skills. Overall, fewer interventions have been implemented in low- and middle-income countries. We identify cross-cutting areas affecting child and adolescent mental health promotion: understanding the problem scope; understanding which components work; understanding how and for whom interventions work in practice; and ensuring supportive infrastructure and political will. Additional evidence, including from participatory approaches, is required to tailor mental health promotive interventions to diverse groups’ needs and support healthy life course trajectories for children and adolescents everywhere.

Psychotherapeutic interventions for childhood posttraumatic stress disorder: an update

PURPOSE OF THE REVIEW

We review treatment outcome studies and systematic reviews for childhood and adolescent posttraumatic stress disorder (PTSD) between January 2020 and August 2022, including studies involving younger children and different treatment delivery methods and models. We address predictors, moderators, treatment engagement, and attrition.

RECENT FINDINGS

Recent randomised controlled trials corroborate earlier trials documenting trauma-focused cognitive behaviour therapy (TF-CBT) as a highly efficacious treatment for PTSD. Evidence for treatment effects in complex PTSD in youth is still sparse. Research on moderators and predictors of treatment continues to be hampered by multiple factors, including a lack of sufficiently large homogeneous trauma samples.

SUMMARY

TF-CBT is a very effective treatment for children and adolescents with PTSD. Further work is needed to (i) demonstrate that task-shifting models utilising lay community health counsellors and peer counsellors can effectively and cost-effectively close the mental health treatment gap that exists world-wide in children and adolescents diagnosed with PTSD, but particularly within low- and middle income countries, and (ii) better understand moderators and predictors of treatment which remains a priority.

Feasibility of a randomised trial of Teaching Recovery Techniques (TRT) with refugee youth: results from a pilot of the Swedish UnaccomPanied yOuth Refugee Trial (SUPpORT)

Background

Although post-traumatic stress is prevalent among unaccompanied refugee minors (URM), there are few evidence-based psychological interventions for this group. Teaching Recovery Techniques (TRT) is a brief, manualised intervention for trauma-exposed youth, which has shown promising results in exploratory studies. The aim of the present study was to assess the feasibility of conducting a randomised controlled trial (RCT) evaluating the use of TRT among URM by investigating key uncertainties relating to recruitment, randomisation, intervention delivery and data collection.

Methods

A 3-month long non-blinded internal randomised pilot trial with a parallel-group design assessed the feasibility of a planned nationwide multi-site RCT. URM with or without granted asylum were eligible if they were 14 to 20 years old, had arrived in Sweden within the last 5 years and had screened positive for symptoms of post-traumatic stress disorder (PTSD). Quantitative data were collected pre- and post-intervention, and 18 weeks after randomisation. On-site individual randomisation (1:1) followed directly after pre-intervention assessment. Participants allocated to the intervention were offered seven weekly group-based TRT sessions. Quantitative pilot outcomes were analysed using descriptive statistics. Qualitative information was gathered through on-site observations and follow-up dialogue with group facilitators. A process for Decision-making after Pilot and feasibility Trials (ADePT) was used to support systematic decision-making in moving forward with the trial.

Results

Fifteen URM (mean age 17.73 years) with PTSD symptoms were recruited at two sites. Three of the youths were successfully randomised to either TRT or waitlist control (TRT n = 2, waitlist n = 1). Fourteen participants were offered TRT for ethical reasons, despite not being randomised. Six (43%) attended ≥ 4 of the seven sessions. Seventy-three percent of the participants completed at least two assessments, with a response rate of 53% at both post-intervention and follow-up.

Conclusions

The findings demonstrated a need for amendments to the protocol, especially with regard to the procedures for recruitment and randomisation. Upon refinement of the study protocol and strategies, an adequately powered RCT was pursued, with data from this pilot study excluded.
