Pilot Randomized Control Trial: Efficacy of a Group-Based Psychosocial Program for Youth with PTSD in the Brazilian Favelas

Systematic Review and Meta-Analysis: Imputing Response Rates for First-Line Psychological Treatments for Posttraumatic Stress Disorder in Youth

OBJECTIVE

Meta-analyses assessing psychological therapies for posttraumatic stress disorder (PTSD) in youth have demonstrated their effectiveness using standardized mean differences. Imputation of response rates (ie, 50% or greater reduction in symptoms) may facilitate easier interpretation for clinicians.

METHOD

We searched 4 databases (MEDLINE, PsycINFO, PTSDPubs, and Web of Science) and screened 1,654 records to include 60 randomized controlled trials (52 trauma-focused cognitive-behavioral therapy [TF-CBT], 8 eye movement desensitization [EMDR]) with a total of 5,113 participants, comparing psychological therapies for PTSD against control conditions in youth. Data from randomized controlled trials of EMDR and TF-CBT for PTSD were used to impute response rates, establishing how many patients display 50% reduction, 20% reduction, and reliable improvement and deterioration (using reliable change indices) in PTSD and depression.

RESULTS

The proportion of youth exhibiting a 50% reduction in PTSD symptoms was 0.48 (95% CI = 0.41-0.55) for TF-CBT, 0.30 (0.24-0.37) for EMDR, and 0.46 (0.39-0.52) for all psychological therapies, compared to 0.20 (0.16-0.24) for youth in control conditions. Reliable improvement was displayed by 0.53 (0.45-0.61; TF-CBT 0.55 [0.46-0.64], EMDR 0.42[0.30-0.55]) of youth receiving psychological therapies, compared to 0.25 (0.20-0.30) of youth in control conditions. Reliable deterioration was seen in 0.01 (0.01-0.02) of youth receiving psychological therapies, compared to 0.13 (0.08-0.20) of youth in control conditions. There was a high degree of heterogeneity in the included studies.

CONCLUSION

Psychological therapies, in particular TF-CBT, for young people with PTSD are effective and unlikely to cause deterioration, with around half of youth receiving TF-CBT exhibiting 50% symptom reduction.

Psychological Interventions for Pediatric Posttraumatic Stress Disorder: A Systematic Review and Network Meta-Analysis

Importance

Pediatric posttraumatic stress disorder (PTSD) is a common and debilitating mental disorder, yet a comprehensive network meta-analysis examining psychological interventions is lacking.

Objective

To synthesize all available evidence on psychological interventions for pediatric PTSD in a comprehensive systematic review and network meta-analysis.

Data Sources

PsycINFO, MEDLINE, Web of Science, and PTSDpubs were searched from inception to January 2, 2024, and 74 related systematic reviews were screened.

Study Selection

Two independent raters screened publications for eligibility. Inclusion criteria were randomized clinical trial (RCT) with at least 10 patients per arm examining a psychological intervention for pediatric PTSD compared to a control group in children and adolescents (19 years and younger) with full or subthreshold PTSD.

Data Extraction and Synthesis

PRISMA guidelines were followed to synthesize and present evidence. Two independent raters extracted data and assessed risk of bias with Cochrane criteria. Random-effects network meta-analyses were run.

Main Outcome and Measures

Standardized mean differences (Hedges g) in PTSD severity.

Results

In total, 70 RCTs (N = 5528 patients) were included. Most RCTs (n = 52 [74%]) examined trauma-focused cognitive behavior therapies (TF-CBTs). At treatment end point, TF-CBTs (g, 1.06; 95% CI, 0.86-1.26; P < .001), eye movement desensitization and reprocessing (EMDR; g, 0.86; 95% CI, 0.54-1.18; P < .001), multidisciplinary treatments (MDTs) (g, 0.88; 95% CI, 0.53-1.23; P < .001), and non-trauma-focused interventions (g, 0.95; 95% CI, 0.62-1.28; P < .001) were all associated with significantly larger reductions in pediatric PTSD than passive control conditions. TF-CBTs were associated with the largest short-term reductions in pediatric PTSD relative to both passive and active control conditions and across all sensitivity analyses. In a sensitivity analysis including only trials with parent involvement, TF-CBTs were associated with significantly larger reductions in pediatric PTSD than non-trauma-focused interventions (g, 0.35; 95% CI, 0.04-0.66; P = .03). Results for midterm (up to 5 months posttreatment) and long-term data (6-24 months posttreatment) were similar.

Conclusions and Relevance

Results from this systematic review and network meta-analysis indicate that TF-CBTs were associated with significant reductions in pediatric PTSD in the short, mid, and long term. More long-term data are needed for EMDR, MDTs, and non-trauma-focused interventions. Results of TF-CBTs are encouraging, and disseminating these results may help reduce common treatment barriers by counteracting common misconceptions, such as the notion that TF-CBTs are harmful rather than helpful.

Effectiveness, efficacy, acceptability, and feasibility of trauma-informed depression, anxiety, and substance use prevention programs for young people aged 12-25 years: A mixed-methods systematic review

BACKGROUND

Mental ill-health and substance use bear significant public health burden on young people. Prevention is key. Trauma-informed approaches to prevention of mental ill-health and substance use demonstrate significant promise, yet it is unclear how well existing approaches work for young people targeting mental ill-health and substance use. This review aimed to assess the effectiveness, feasibility, and acceptability of trauma-informed mental ill-health and/or substance use prevention programs for young people.

METHODS

We searched the PsycINFO, CINAHL, Embase, MEDLINE, and Cochrane Library reference databases for peer-reviewed studies of trauma-informed mental ill-health and/or substance use prevention programs for young people published between 2013 and 2022. Studies in any language were included and reference lists of included articles were scanned for additional studies of relevance.

RESULTS

In total, 30 studies were included in this review, comprising five randomized controlled trials (RCTs), seven non-RCTs, 10 quasi-experimental designs, and eight qualitative studies. Among the 30 studies, 27 unique trauma-informed prevention interventions were detailed. Eighteen studies reported statistically significant decreases in mental ill-health, and two studies reported significant decreases in substance use outcomes among participants, up to 6 months following the interventions. Most preventative interventions with statistically significant effects were selective (rather than universal or indicated) in their approach (n = 10, 55%). Broad acceptability and feasibility of trauma-informed prevention programs was observed among studies reporting this information though most quantitative studies were at high risk of bias and/or did not include a control group, whilst qualitative studies tended to report research conducted without a priori research aims.

DISCUSSION

This review synthesizes for the first-time evidence on the effectiveness (or efficacy), feasibility, and acceptability of trauma-informed mental ill-health and/or substance use programs for young people, especially for those exposed to traumatic or adverse experiences. While there are promising efficacy outcomes, further research conducting rigorous, well-powered RCTs is required for large-scale evaluation and scaling of the potential preventative benefits of such programs.

A systematic review of non-clinician trauma-based interventions for school-age youth

Exposure to adverse childhood experiences (ACEs) is recognised globally as a risk factor for health problems in later life. Awareness of ACEs and associated trauma is increasing within schools and educational settings, as well as the demand for supportive services to address needs. However, there is a lack of clear evidence for effective interventions which can be delivered by non-clinicians (e.g., the school staff themselves). Thus, we undertook a systematic review to answer the question: What evidence exists for the efficacy of non-clinician delivered trauma-based interventions for improving mental health in school-age youth (4-18 years) who have experienced ACEs? The protocol for the review is registered in the PROSPERO International Prospective Register of Systematic Reviews (ID: CRD42023417286). We conducted a search across five electronic databases for studies published between January 2013 and April 2023 that reported on interventions suitable for non-clinician delivery, were published in English in the last 10 years, and involved participants aged 4-18 years (school-age) that had exposure to ACEs. Of the 4097 studies identified through the search, 326 were retrieved for full text screening, and 25 were included in the final review. Data were extracted from included articles for analysis and selected studies were quality assessed using validated assessment tools. Data were analysed through narrative synthesis. There was considerable heterogeneity in study design, outcome measures, and the interventions being studied. Interventions included CBT, mindfulness and art-based programs. A key finding was that there is a lack of high-quality research evidence to inform non-clinician delivered trauma-informed interventions. Many included studies were weak quality due to convenience sampling of participants and potential bias. Cognitive Behavioural Therapy (CBT)-based approaches are tentatively suggested as a suitable target for future rigorous evaluations of interventions addressing ACE-related trauma recovery and mental health improvement in school-age youth.

Teaching Recovery Techniques (TRT) to Ukrainian children and adolescents to self-manage post-traumatic stress disorder (PTSD) symptoms following the Russian invasion of Ukraine in 2022 - The first 7 months

BACKGROUND

The Russian invasion of Ukraine in February 2022 prompted many to provide mental health input, especially trauma management, to Ukrainian children and adolescents (C/A) exposed to it.

METHODS

Rapid cascade training of 200 Ukrainian psychologists during 2022 to provide, in pairs, free of charge and without selection, TRT courses of 4-6, 90 min sessions online or face to face to C/A 7 to 23 years in Ukraine and those migrating abroad. CRIES-8 PTSD questionnaires were administered at the beginning and end of the courses during May-December 2022. Age, gender, their geographical war risk, and whether C/A had stayed or migrated elsewhere were collected. A CRIES-8 score of ≥17/40 defined likely PTSD.

RESULTS

3123 C/A completed an initial CRIES-8 questionnaire with matching demographics, 2737 a questionnaire at the end and 1798 both. At entry to TRT, likely PTSD was greater in females (65 %) than males (52 %, p < 0.001) declining with increasing age, particularly in males (p < 0.001). Migration had mixed effects and moving to lower war risk areas or abroad did not reduce PTSD risk. TRT benefited 68 % of C/A overall by reducing CRIES-8 from ≥17 to <17, the rate increasing the more experienced the TRT facilitators became (p < 0.0001). Online and face to face outcomes were the same.

LIMITATIONS

The chaos of war prevented capture of all potential C/A questionnaires and long-term repeat testing not yet undertaken.

CONCLUSIONS

Even in the chaos of war, effective mental health input can be rapidly and cheaply (c.50 USD/child) provided and should be encouraged.

Training non-specialists in teaching recovery techniques (TRT) to help traumatised children in humanitarian settings: a qualitative analysis of experiences gained from 20 years of practice

BACKGROUND

Although several manuals and guidelines have been developed to enhance the quality of task-sharing interventions, it remains challenging to train non-professional personnel in mental health and psychosocial support. Practitioners must translate general recommendations into practical applications to make them relevant in demanding contexts. However, limited research exists on practical experiences with standardised programmes in the field.

AIM

To explore how experiences gained from the training of first-line health providers in a low-threshold intervention for children with trauma symptoms may guide implementation of such interventions in local communities in low-income countries.

METHOD

We summarise 20 years of experience in the training of first-line health providers, teachers, and school counsellors in providing a low-threshold intervention. The intervention is called teaching recovery techniques (TRT), developed by the Children and War Foundation (CAW). Field notes containing notes from trainings and oral, informal feedback from participants are analysed using thematic analysis, a method well-suited for identifying, analysing, and reporting patterns, or themes, within data in qualitative research.

FINDINGS

The analysis showed three main themes/ challenges: (1) Who can conduct the TRT intervention? (2) What form and content should the training take? (3) How can the intervention be used in a responsible way to follow the 'do no harm' principle? We discuss the implications of the findings for trainings in scalable interventions and further research.

Local understandings of PTSD and complex PTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city, Brazil

BACKGROUND

Adolescents in low-resource urban settings in Brazil are often exposed to high levels of trauma that can result in post-traumatic stress disorder (PTSD). However, preliminary evidence indicates that PTSD tends to be under-reported in Brazilian health services, despite the high prevalence of trauma. Additionally, little is known about the perceived applicability among clinicians of the new ICD-11 diagnosis of complex PTSD (CPTSD), despite its potential relevance for contexts of chronic trauma. The current study investigated local understandings of PTSD and CPTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city.

METHODS

Semi-structured interviews were conducted with 58 health professionals working at both the primary care and specialized mental health levels in two areas of São Paulo city with high levels of community violence.

RESULTS

Most participants knew about PTSD, but most did not know about CPTSD. There were mixed views concerning the commonality of PTSD among adolescents exposed to community violence. Many participants reported having no experience working with patients with the PTSD diagnosis. According to some, community violence was normalized by adolescents and health professionals, and did not result in PTSD. Others highlighted how they did not use psychiatric diagnoses in their practice, had critical perspectives towards psychiatric diagnoses and/or PTSD, or simply knew little about PTSD. Furthermore, many highlighted how the chronic nature of multiple traumas experienced by adolescents often resulted in complex clinical presentations characterised by many symptoms beyond PTSD. The diagnosis of CPTSD was considered appropriate to the context by many participants as it captured the complex traumatic histories and symptom presentations of adolescents exposed to community violence in Brazil.

CONCLUSIONS

These findings have important implications for the assessment and treatment of mental health among adolescents exposed to community violence in Brazil.

Posttraumatic stress disorder among adolescents in Brazil: a cross-sectional study

BACKGROUND

The frequency of trauma and different types of violence exposure in urban areas and their effects on the mental health of adolescents in developing countries are poorly investigated. Most information about traumatized young people comes from war scenarios or disasters. This study aimed to determine the prevalence of PTSD in trauma-exposed students in a low-resource city of the state of Rio de Janeiro, Brazil. The effects of sociodemographic and individual and family factors in the development of PTSD were also investigated.

METHODS

Through multi-stage cluster sampling, 862 adolescents (Mage = 15 years old, 65% female) from public and private schools in the city of São Gonçalo were selected for the study. Self-rating structured questionnaires were applied to assess sociodemographic profile, exposure to physical and psychological violence (family, school, community), sexual abuse, social support, social functional impairment, resilience, and posttraumatic stress disorder. The data were grouped in blocks regarding sociodemographic, individual, family, and community variables. For statistical analysis, chi-square, Fisher's exact test, and logistic regression were performed.

RESULTS

The PTSD prevalence was 7.8% among adolescents. Boys were exposed to significantly higher number of events of community violence, while girls to family violence. The adjusted odds ratio (OR) for PTSD were statistically significant for age (OR, 1.45, [95% CI, 1.043-2.007]), social functional impairment (OR, 4.82, [95% CI, 1.77-13.10]), severe maternal physical violence (OR, 2.79, [95% CI, 0.79-9.93]), psychological violence by significant people (OR, 3.96, [95% CI, 1.89-8.31]) and a high number of episodes of community violence (OR, 3.52, [95% CI, 1.47-8.40).

CONCLUSIONS

There was a high prevalence of PTSD within this population associated with exposure to violence. Not only physical, but also psychological violence contributed to PTSD. The results also raise awareness to the differences in life trajectories between boys and girls regarding violence. These differences need to be better understood in order to enable the development of effective preventative interventions. Treating and preventing mental health disorders presents a challenge for countries, especially those with a lower degree of social and economic development and high community violence.
