Mediators of Outcome in Trauma-Focused Psychotherapy with Youth: A Systematic Review

This article aimed to provide a systematic narrative synthesis of existing studies on the mediators of change in psychotherapy with adolescents (10-19 years) and transition age youth (TAY) (20-29 years) who have experienced trauma-related symptoms or posttraumatic disorder. Additionally, we were interested in identifying psychotherapy-, trauma type-, and clients' age- and gender-specific mediators of treatment outcome. Following the preferred reporting items for systematic reviews and meta-analyses, a total of 3,723 studies published in PubMed and PsycINFO databases were screened against inclusion criteria, revealing 15 eligible studies. No studies with only TAY were found; therefore, all results were limited to therapy with adolescents. Cognitive mediators were tested in 66% of selected studies, followed by parents/family-related, mental-health-related, therapy-related, and behavioral mediators. Moderate evidence was found for posttraumatic cognitions, whereas therapeutic alliance seemed to be a promising candidate for future research. Striking absence of non-cognitive-behavioral therapy interventions, emotional and adolescent-specific mediators, as well as studies with males and in non-Western societies was evident. Future original studies would benefit from applying methodological rigor in respect to mediation testing.

Identifying effective moderators of cognitive behavioural trauma treatment with caregiver involvement for youth with PTSD: a meta-analysis

Children can develop post-traumatic stress disorder (PTSD) and mental health symptoms after traumatic events. This meta-analysis evaluated the influence of moderators of cognitive behavioural trauma treatment (CBTT) with caregiver involvement in traumatized children. A total of 28 studies were included, with 23 independent samples and 332 effect sizes, representing the data of 1931 children (M age = 11.10 years, SD = 2.36). Results showed a significant medium overall effect (d = 0.55, t = 2.478, p = 0.014), indicating CBTT with caregiver involvement was effective in treating PTSD (d = 0.70), with somewhat smaller effect sizes for internalizing, externalizing, social, cognitive and total problems (0.35 < d > 0.48). The positive treatment effect was robust; we found somewhat smaller effect sizes at follow-up (d = 0.49) compared to post-test (d = 0.57) assessments. Furthermore, several sample (i.e. child's age, gender, and trauma event), programme (i.e. the duration of treatment, number of sessions), study (i.e. control condition, type of instrument, informant, type of sample), and publication (i.e. publication year and impact factor) characteristics moderated the treatment outcomes of the child. In sum, the results of our meta-analysis might help to improve the effectiveness of cognitive behavioural trauma treatment for youth with PTSD, and guide the development of innovative trauma interventions that involve caregivers. Implications for theory and practice are discussed.

Stability of Treatment Effects and Caregiver-Reported Outcomes: A Meta-Analysis of Trauma-Focused Cognitive Behavioral Therapy for Children and Adolescents

The efficacy of trauma-focused treatments for children and adolescents is well researched. However, less is known about the long-term and caregiver-reported effects. Searched databases were PsychInfo, MEDLINE, Cochrane Library, PTSDPubs, PubMed, Web of Science, and OpenGrey. Treatment effects of trauma-focused cognitive behavioral therapy (TF-CBT) were computed at 12-month follow-up with posttraumatic stress symptoms (PTSS) as primary outcome and symptoms of depression, anxiety, and grief as secondary outcomes. Concordance between participant and caregiver ratings were investigated. TF-CBT showed large improvements across all outcomes from pre-treatment to 12-month follow-up (PTSS: g = 1.71, CI 1.27-2.15) and favorable results compared to active treatments and treatment as usual at 12-month follow-up (PTSS: g = .35, CI .13-.56). More pronounced effects were found in group settings. No significant differences were detected between participant and caregiver ratings with high reliability across almost all outcomes and assessment points. TF-CBT is a reliable treatment for pediatric PTSS and secondary symptoms with stable results at 12-month follow-up.

Systematic Review: Patient and Public Involvement of Children and Young People in Mental Health Research

OBJECTIVE

Patient and public involvement (PPI) is an essential ethical component in mental health research, and represents a major opportunity to improve translational mental health research. The goals of this review were to (1) provide a comprehensive overview of empirical research focusing on PPI of children and young people (CYP) in mental health research studies; (2) evaluate the results with CYP and parents of those affected; and (3) derive recommendations for PPI of CYP in future mental health research studies.

METHODS

Based on an extensive literature review following the PRISMA guidelines, studies including CYP (age range: 0-21 years) in mental health research were identified and examined along a two-part analysis process considering their usability for mental health research. The conclusions drawn from the studies concerning CYP involvement were summarized and recommendations derived.

RESULTS

Overall, 19 articles reported PPI of CYP (age range: 10-26 years) in mental health research and were included for further analyses. The integrated studies differed in the type of PPI, and in the way the participation and involvement processes were presented.

CONCLUSION

Progress has been made in engaging CYP in mental health research, but there is a need for international standards, operationalization, and evaluation measures. Future research should go beyond merely reporting the PPI process itself. It should clearly indicate how and to what extent feedback from these PPI members was incorporated throughout the research process.

Childhood trauma is prevalent and associated with co-occurring depression, anxiety, mania and psychosis in young people attending Australian youth mental health services

OBJECTIVES

Childhood trauma is common and associated with mental ill health. While high rates of trauma are observed across individual disorders, there is evidence that trauma is associated with an admixture of affective, anxiety and psychotic symptoms in adults. Given that early onset of mental disorder and trauma exposure herald poor outcomes, it is important to examine trauma prevalence rates in youth mental health services and to determine whether this trauma-related clustering is present in help-seeking young people.

METHODS

We used data from the Transitions Study, a longitudinal investigation of young people attending headspace youth mental health services in Australia between January 2011 and August 2012. Participants were 775 young people aged 12-25. Childhood trauma was assessed using the Childhood Trauma Questionnaire. Multinomial regression was used to assess whether reported childhood trauma was more strongly associated with the co-occurrence of depression, anxiety, mania and psychosis symptoms than with any one in isolation.

RESULTS

Approximately 84% of participants reported some form of abuse (emotional: 68%; physical: 32%; sexual: 22%) or neglect (emotional: 65%; physical: 46%). Exposure to multiple trauma types was common. Childhood trauma was significantly associated with each symptom domain. More severe childhood trauma was more strongly associated with the co-occurrence of symptoms than with any one symptom domain in isolation, such that more severely trauma-exposed young people were more likely to experience increased symptom clustering.

CONCLUSIONS

Childhood trauma is pervasive in youth mental health services and associated with a symptom profile that cuts across traditional diagnostic boundaries.

Therapists' Perceived Competence in Delivering Trauma-Focused Cognitive Behavioral Therapy During Statewide Learning Collaboratives

The learning collaborative (LC), a multi-component training and implementation model, is one promising approach to address the need for increased availability of trauma-focused evidence-based practices. The current study used data from four cohorts of a statewide LC on Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) to 1) evaluate pre- to post-LC changes in therapists' perceived competence in delivering TF-CBT and 2) explore therapist and contextual factors related to therapists' perceived TF-CBT competence. Therapists (N = 237) completed pre- and post-LC measures of practice information, interprofessional collaboration, organizational climate, and TF-CBT knowledge, perceived competence, and use. Findings indicated therapists' perceived TF-CBT competence significantly increased, pre- to post-LC (d = 1.31), with greater use of trauma-focused practices at pre-training and more TF-CBT training cases completed predicting greater pre- to post-LC gains in perceived TF-CBT competence. These findings highlight the need to assist therapists in identifying and completing training cases to promote competence and implementation.

Comparative effectiveness of psychotherapies in adults with posttraumatic stress disorder: a network meta-analysis of randomised controlled trials

BACKGROUND

Evidence on the long-term comparative effectiveness of posttraumatic stress disorder (PTSD) psychotherapies in adults remains unknown. Therefore, we performed an extensive network meta-analysis of randomised controlled trials (RCTs) to determine the comparative effectiveness of psychotherapies for people diagnosed with PTSD.

METHODS

A comprehensive search was conducted in Cochrane library, Embase, Medline-OVID, PubMed, Scopus, and Psych-Info until March 2021. Studies on the effectiveness of cognitive processing therapy (CPT), cognitive therapy (CT), eye movement desensitisation reprocessing (EMDR), narrative exposure therapy (NET), prolonged exposure (PE), cognitive behavioural therapy (CBT), present-centred therapy (PCT), brief eclectic psychotherapies (BEP), psychodynamic therapy (PDT) or combination therapies compared to no treatment (NT) or treatment as usual (TAU) in adults with PTSD were included. Frequentist and Bayesian approaches were used for analysis in R-software.

RESULTS

We included 98 RCTs with 5567 participants from 18 897 studies. CPT, EMDR, CT, NET, PE, CBT, and PCT were significant to reduce PTSD symptoms (SMD range: -1.53 to -0.75; Certainty: very low to high) at immediate post-treatment and ranked accordingly. Longitudinal analysis found EMDR (1.02) and CPT (0.85) as the significant therapies with large effect size in short-term and long-term follow-up, respectively. NET and CPT showed higher proportion of loss of PTSD diagnosis (RR range: 5.51-3.45) while there were no significant psychotherapies for retention rate compared to NT.

CONCLUSIONS

Our findings provide evidence for improving current guidelines and informing clinical decision-making for PTSD management. However, the best PTSD treatment plan should be tailored to patients' needs, characteristics, and clinician expertise.

Unified Protocol vs Trauma-Focused Cognitive Behavioral Therapy Among Adolescents With PTSD

Harmful consequences of COVID-19, such as prolonged quarantine, lack of social contact, and especially loss of parents or friends, can negatively impact children and adolescents' mental health in diverse ways, including engendering posttraumatic stress symptoms. Our study is the first to compare the transdiagnostic Unified Protocol for the Treatment of Emotional Disorders in Adolescents (UP-A; Ehrenreich et al., 2009; Ehrenreich-May et al., 2017) with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) in terms of outcomes related to PTSD symptoms (COVID-19-related vs. COVID-19 unrelated PTSD) and comorbid symptoms (i.e., anxiety, depression) and other measures (i.e., emotion regulation, self-injury, anger). Individuals diagnosed with PTSD were randomly assigned to the UP-A (n = 46) or TF-CBT group (n = 47), administered the SCID-5 and a battery of measures and followed up posttreatment and then after 3, 6, and 9 months. Ninety-three adolescents with PTSD were enrolled, 45% boys and 61% COVID-19-related PTSD. We adopted an intention-to-treat approach. At the initial post-intervention assessment, except for emotion regulation and unexpressed angry feelings, in which UP-A participants reported greater reductions, no significant differences in other variables were secured between the UP-A and TF-CBT. However, at follow-up assessments, the UP-A evidenced significantly better outcomes than TF-CBT. We found support for the UP-A compared with TF-CBT in treating adolescents with PTSD, regardless of COVID-19-related PTSD status, in maintaining treatment effectiveness over time.

Victims of Child Abuse Dropping Out of Trauma-Focused Treatment: A Meta-Analysis of Risk Factors

A substantial number of children who experienced child maltreatment drop out of evidence-based trauma-focused treatments (TF-CBT). Identifying child, family, and treatment-related factors associated with treatment dropout is important to be able to prevent this from happening and to effectively treat children's trauma-related symptoms. Methods: A quantitative review was performed based on a systematic synthesis of the literature on potential risk factors for dropout of trauma-focused treatment in maltreated children. Results: Eight studies were included, that examined TF-CBT, reporting on 139 effects of potential risk factors for dropout. Each factor was classified into one of ten domains. Small but significant effects were found for the "Demographic and Family" risk domain (r = .121), with factors including being male, child protective services involvement or placement, and minority status, and for the "Youth Alliance" risk domain (r = .207), with factors including low therapist-child support and low youth perception of parental approval. Moderator analyses suggested that family income and parental education may better predict the risk for TF-CBT dropout than other variables in the "Demographic and Family" domain. Conclusions: Our results provide a first overview of risk factors for dropout of trauma-focused treatments (TF-CBT) after child maltreatment, and highlight the role of the therapeutic relationship in this.

Exploring the Mechanisms in Cognitive Behavioural Therapy for Anxious Children: Does Change in Emotion Regulation Explain Treatment Effect?

Cognitive behavioural therapy (CBT) for childhood anxiety has shown moderate effects. However, inconsistency in findings during the last decades of treatment research and lack of measurable treatment gains over time has led to a call for optimizing interventions by identifying the active mechanisms involved and for whom such interventions are effective. It has been suggested that the moderate effects may be explained by the fact that emotion regulation rarely is directly targeted in CBT-interventions and that interventions may be more effective for children with a certain level of problems with emotion regulation. Using data from a randomized controlled trial with 160 children and their mothers at baseline (t1) and posttreatment (t2), we examined whether being randomized to CBT predicted change in anxiety symptoms from t1 to t2 and whether this change was mediated by change in emotion regulation from t1 to t2. We also investigated whether the strength of this indirect pathway depended on the level of emotion regulation problems at baseline. Latent baseline target moderated mediation analyses within a structural equation modelling framework were conducted. Results showed a significant indirect pathway between receiving CBT to improved emotion regulation, which again was significantly associated with reductions in anxiety symptoms. The findings suggest that the effect of CBT is similar for children irrespective of initial levels of emotion regulation measured broadly, whereas there was some evidence of a baseline moderation effect of the subdomain emotional control. Emotion regulation, and especially emotional control, seems to be an underlying mechanism for positive effects of CBT for anxiety disorders in children, possibly indicating that a greater emphasis on emotion regulation may optimize the intervention.

Stepping Together in Stepped Care Trauma-Focused Cognitive Behavioral Therapy: Case Report of Core Components

New service delivery systems are needed to expand the reach of evidence-based practices for childhood trauma. Cognitive behavioral therapy is an effective approach for treating -childhood trauma, yet treatment barriers remain. Stepped care models that incorporate parent-led -treatment with therapist assistance may be one approach to improve access. This case study highlights the core components of a parent-led therapist-assisted treatment called Stepping Together that serves as a Step 1 treatment within a stepped care model. The components and structure of Stepping Together are described, along with excerpts from therapy sessions to illustrate the therapist's implementation of the model. Results of the case, in which improvements occurred, are presented. Stepping Together, a parent-led therapist-assisted first-line treatment within stepped care trauma-focused cognitive behavioral therapy, may be an effective treatment for some children after trauma and their caregivers, although more research is needed.

A systematic review and meta-analysis of trauma-focused cognitive behavioral therapy for children and adolescents

BACKGROUND

Among minors, posttraumatic stress symptoms (PTSS) are a common consequence of traumatic events requiring trauma-focused treatment.

OBJECTIVE

This meta-analysis quantified treatment effects of trauma-focused cognitive behavioral therapy (TF-CBT) with PTSS as primary outcome and symptoms of depression, anxiety, and grief as secondary outcomes.

PARTICIPANTS AND SETTING

Inclusion criteria for individual settings: (1) patients aged between 3 and 21, (2) at least one traumatic event, (3) minimum 8 sessions of (4) TF-CBT according to Cohen, Mannarino and Deblinger (2006, 2017), (5) a quantitative PTSS measure at pre- and post-treatment, (6) original research only. Inclusion criteria for group settings: had to involve (1) psychoeducation, (2) coping strategies, (3) exposure, (4) cognitive processing/restructuring, (5) contain some reference to the manual and no minimum session number was required.

METHODS

Searched databases were PsychInfo, MEDLINE, Cochrane Library, PTSDPubs, PubMed, Web of Science, and OpenGrey.

RESULTS

4523 participants from 28 RCTs and 33 uncontrolled studies were included. TF-CBT showed large improvements across all outcomes from pre- to post-treatment (PTSS: g = 1.14, CI 0.97-1.30) and favorable results compared to any control condition including wait-list, treatment as usual, and active treatment at post-treatment (PTSS: g = 0.52, CI 0.31-0.73). Effects were more pronounced for group settings. We give pooled estimates adjusted for risk of bias and publication bias, which initially limited the quality of the analyzed data.

CONCLUSIONS

TF-CBT is an effective treatment for pediatric PTSS as well as for depressive, anxiety, and grief symptoms. It is superior to control conditions, supporting international guidelines recommending it as a first-line treatment.

Cortical activation predicts posttraumatic improvement in youth treated with TF-CBT or CCT

BACKGROUND

Identifying neural activation patterns that predict youths' treatment response may aid in the development of imaging-based assessment of emotion dysregulation following trauma and foster tailored intervention. Changes in cortical hemodynamic activity measured with functional near-infrared spectroscopy (fNIRS) may provide a time and cost-effective option for such work. We examined youths' PTSD symptom change following treatment and tested if previously identified activation patterns would predict treatment response.

METHODS

Youth (N = 73, mean age = 12.97, SD = 3.09 years) were randomly assigned to trauma-focused cognitive behavioral therapy (TF-CBT), cue-centered therapy (CCT), or treatment as usual (TAU). Parents and youth reported on youth's PTSD symptoms at pre-intervention, post-intervention, and follow-up. Neuroimaging data (N = 31) assessed at pre-intervention were obtained while youth engaged in an emotion expression task. Treatment response slopes were calculated for youth's PTSD symptoms.

RESULTS

Overall, PTSD symptoms decreased from pre-intervention through follow-up across conditions, with some evidence of relative benefit of TF-CBT and CCT over TAU but significant individual variation in treatment response. Cortical activation patterns were correlated with PTSD symptom improvement slopes (r = 0.53). In particular, cortical responses to fearful and neutral facial stimuli in six fNIRS channels in the bilateral dlPFC were important predictors of PTSD symptom improvement.

CONCLUSIONS

The use of fNIRS provides a method of monitoring and assessing cortical activation patterns in a relatively inexpensive and portable manner. Associations between functional activation and youths' PTSD symptoms improvement may be a promising avenue for understanding emotion dysregulation in clinical populations.

Predictors of nonresponse and drop-out among children and adolescents receiving TF-CBT: investigation of client-, therapist-, and implementation factors

Background

There is a paucity of evidence about effective implementation strategies to increase treatment response and prevent drop-out among children receiving evidence-based treatment. This study examines patient, therapist, and implementation factors and their association to nonresponse and drop-out among youth receiving Trauma-Focused Cognitive Behavioral Therapy (TF-CBT).

Methods

Youth (n = 1240) aged 6–18 (M = 14.6) received TF-CBT delivered by 382 TF-CBT therapists at 66 clinics. Odds ratio analyses were used to investigate whether pretreatment child (age, gender, number of trauma experiences, post-traumatic stress symptoms (PTSS), therapist (education), and implementation strategy factors (high-low, low-low, low–high intensity therapist and leadership training respectively) or tele-mental health training during the Covid-19 pandemic are associated with nonresponse (above clinical PTSS level post-treatment) and drop-out (therapist-defined early termination). Fidelity checks were conducted to ensure that TF-CBT was used consistently.

Results

One fourth of the children (24.4%) were nonresponders and 13.3 percent dropped out. Exposure to three or more traumatic experiences were related to nonresponse and drop-out. Higher baseline PTSS was related to a higher probability of nonresponse. There was no effect of therapist education or child gender on nonresponse and drop-out, whereas children over 15 years had a higher likelihood of both. After controlling for baseline PTSS, the effect of age on nonresponse was no longer significant. Drop-out was related to fewer sessions, and most dropped out during the first two phases of TF-CBT. Fidelity was high throughout the different implementation phases. High-intensity therapist training was related to a lower probability of both nonresponse and drop-out, whereas low therapist and leadership training were related to a higher likelihood of both. Multivariate analysis revealed higher child age and higher PTSS baseline scores as significant predictors of nonresponse, and number of trauma experiences (> = 3) at baseline as the only predictor of drop-out.

Conclusions

High-intensity therapist training seem key to prevent patient nonresponse and drop-out. Leadership training might positively affect both, although not enough to compensate for less intensive therapist training. More complex cases (higher PTSS and exposure to more traumas) predict nonresponse and drop-out respectively, which underscores the importance of symptom assessment to tailor the treatment. The lack of predictive effect of therapist education increases the utilization of TF-CBT.

Therapists' Perceived Competence in Trauma-Focused Cognitive Behavioral Therapy and Client Outcomes: Findings From a Community-Based Learning Collaborative

This study examined therapists' perceived competence in Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and its association with youth treatment outcomes (posttraumatic stress and depression). Participants included 99 community therapists enrolled in a TF-CBT-focused Learning Collaborative (LC), along with one of their randomly selected TF-CBT training cases. Analyzed data included: 1) caregiver/youth-reported posttraumatic stress and depressive symptoms, pre- and post-treatment, and 2) therapist-perceived competence with TF-CBT components across treatment delivery. Youth- and caregiver-reports indicated large, significant pre- to post-treatment decreases in youth posttraumatic stress (ds = 1.10-1.30, ps < .001) and depressive symptoms (d = 1.01, p < .001). Higher therapist-perceived competence with TF-CBT predicted positive treatment responses for posttraumatic stress (ds = 0.38-0.39, ps = .03) and depression (d = 0.25), though only the former association was significant (ps = .03 vs. p = .15). Findings highlight the need to monitor and improve therapists' competencies to enhance clinical outcomes for trauma-exposed youth and suggest that LCs may be an effective training/implementation model to help achieve those critical goals.

Trauma-focused cognitive behavioral therapy for children and youth in low and middle-income countries: A systematic review

BACKGROUND

Trauma-focused cognitive behavioral therapy (TF-CBT) has been identified as a gold standard treatment for childhood posttraumatic stress disorder (PTSD) in Western countries. More recently, TF-CBT has emerged in the literature as an area of interest for children and youth affected by conflict and war in low- and middle-income countries (LMIC).

METHODS

The present systematic review assesses the current evidence base of TF-CBT for children and youth in LMIC, with a focus on conflict-affected countries. A total of 143 articles were identified, of which 11 articles, representing 1,354 participants, met the proposed inclusion criteria.

RESULTS

Results showed that the majority of the studies identified were conducted in low-resource community settings in East or Central Africa (n = 8). It was also found that cultural considerations were taken into account in TF-CBT delivery to meet the needs of local populations. Additionally, measures were translated and validated for local use.

CONCLUSIONS

Findings of outcome data indicated that TF-CBT was effective in treating trauma-related symptoms and improving psychosocial functioning in children and adolescents in LMICs. Given the limited number of published literature available in this area, further studies are needed to conclude when and for whom trauma-focused interventions are most relevant.

Examining the effectiveness of trauma-focused cognitive behavioral therapy on children and adolescents' executive function

BACKGROUND

Children and adolescents impacted by childhood trauma often demonstrate executive function difficulties, which negatively affect self-regulation and potentiate the risk for trauma-related psychopathology and functional impairment. Evidence-based treatments for traumatized youth such as Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) aim to equip youth directly with skills for effective self-regulation and may thus also improve executive function. Moreover, adolescence is a sensitive period for executive function development, and interventions aimed at improving executive function may confer greater benefits for adolescents relative to school-aged children. No study has examined executive function improvements during TF-CBT or the potential differences in these outcomes between children and adolescents.

OBJECTIVE

In the current study, we examined changes in caregiver-reported executive function difficulties during TF-CBT among children ages 6 to 11 and adolescents ages 12 to 17.

PARTICIPANTS AND SETTING

Participants were 278 racially and ethnically diverse youth with interpersonal trauma histories and their caregivers enrolled in a community-based effectiveness trial of TF-CBT in an urban setting. Caregivers reported on youth executive function at pre, mid, and posttreatment assessments.

RESULTS

Both children and adolescents demonstrated reductions in global executive function difficulties during TF-CBT. Improvements were seen across domains of emotional, behavioral, and attentional control and problem solving, with larger effect sizes for adolescents. Follow-up analyses indicated that executive function improvements were positively associated with PTSD symptom reduction in adolescents, but not in children.

CONCLUSIONS

Findings add to the growing evidence of the effectiveness of TF-CBT among youth and highlight caregiver-reported executive function as a potential treatment target during TF-CBT.

A Web-Based Cognitive Behavioral Therapy, Mindfulness Meditation, and Yoga Intervention for Posttraumatic Stress Disorder: Single-Arm Experimental Clinical Trial

BACKGROUND

Posttraumatic stress disorder (PTSD) is a debilitating, undertreated condition. The web-based delivery of cognitive behavioral therapy supplemented with mindfulness meditation and yoga is a viable treatment that emphasizes self-directed daily practice.

OBJECTIVE

This study aims to examine the effectiveness of a web-based cognitive behavioral therapy, mindfulness, and yoga (CBT-MY) program designed for daily use.

METHODS

We conducted an 8-week, single-arm, experimental, registered clinical trial on adults reporting PTSD symptoms (n=22; aged 18-35 years). Each participant received web-based CBT-MY content and an hour of web-based counseling each week. Pre-post outcomes included self-reported PTSD symptom severity, depression, anxiety, chronic pain, and mindfulness. Pre-post psychophysiological outcomes included peak pupil dilation (PPD) and heart rate variability (HRV). HRV and PPD were also compared with cross-sectional data from a non-PTSD comparison group without a history of clinical mental health diagnoses and CBT-MY exposure (n=46).

RESULTS

Pre-post intention-to-treat analyses revealed substantial improvements in PTSD severity (d=1.60), depression (d=0.83), anxiety (d=0.99), and mindfulness (d=0.88). Linear multilevel mixed models demonstrated a significant pre-post reduction in PPD (B=-0.06; SE=0.01; P<.001; d=0.90) but no significant pre-post change in HRV (P=.87). Overall, participants spent an average of 11.53 (SD 22.76) min/day on self-directed mindfulness practice.

CONCLUSIONS

Web-based CBT-MY was associated with clinically significant symptom reductions and significant PPD changes, suggesting healthier autonomic functioning. Future randomized controlled trials are needed to further examine the gains apparent in this single-arm study.

Common elements of evidence-based trauma therapy for children and adolescents

Background: Numerous evidence-based trauma therapies for children and adolescents have been developed over several decades to minimize the negative outcomes of post-traumatic stress disorder (PTSD). However, PTSD remains a complex construct and is associated with pervasive problems and high comorbidity. To gain more insight, much could be learnt from the similarities in trauma therapies. Objective: The purpose of this study is to derive common elements from evidence-based trauma therapies for children and adolescents. Method: Therapies were selected from a literature search. Five evidence-based trauma therapies were included in this study. A common element list was created through an existing and modified Delphi method, with a diverse group of Dutch trauma therapists. An element was deemed common when it appeared in three or more of the therapies. The final list was presented to international experts on the included trauma therapies. Results: A substantial commonality of techniques and mechanisms was found across the five evidence-based trauma therapies for children and adolescents, showing a strong overlap between therapies. Conclusion: The identified elements create a basis for research and clinical practice, with regard to targeted trauma therapies tailored to each individual child and his or her support system. This promotes therapy modules that are more flexible and accessible for both therapists and clients, in every environment, from specialized psychiatric units to sites with meagre resources. With current integrated knowledge, we can enhance the effectiveness of child psychiatry and refine trauma therapies.

HIGHLIGHTS

Using a modified Delphi method, a substantial commonality of techniques and mechanisms is found in evidence-based trauma therapies for children and adolescents.Understanding the techniques and mechanisms of trauma therapy could be of help in refining upcoming therapies, and creates a basis for future research.Commonalities promote therapy modules that are more flexible and accessible for both therapists and clients, in environments ranging from specialized psychiatric units to sites with meagre resources.

Trauma-focused treatments for depression. A systematic review and meta-analysis

BACKGROUND

Trauma-focused treatments (TFTs) have demonstrated efficacy at decreasing depressive symptoms in individuals with PTSD. This systematic review and meta-analysis evaluated the effectiveness of TFTs for individuals with depression as their primary concern.

METHODS

A systematic search was conducted for RCTs published before October 2019 in Cochrane CENTRAL, Pubmed, EMBASE, PsycInfo, and additional sources. Trials examining the impact of TFTs on participants with depression were included. Trials focusing on individuals with PTSD or another mental health condition were excluded. The primary outcome was the effect size for depression diagnosis or depressive symptoms. Heterogeneity, study quality, and publication bias were also explored.

RESULTS

Eleven RCTs were included (n = 567) with ten of these using EMDR as the TFT and one using imagery rescripting. Analysis suggested these TFTs were effective in reducing depressive symptoms post-treatment with a large effect size [d = 1.17 (95% CI: 0.58~ 1.75)]. Removal of an outlier saw the effect size remain large [d = 0.83 (95% CI: 0.48~ 1.17)], while the heterogeneity decreased (I2 = 66%). Analysis of the 10 studies that used EMDR also showed a large effect [d = 1.30 (95% CI: 0.67~1.91)]. EMDR was superior to non trauma-focused CBT [d = 0.66 (95% CI: 0.31~1.02)] and analysis of EMDR and imagery rescripting studies suggest superiority over inactive control conditions [d = 1.19 (95% CI: 0.53~ 1.86)]. Analysis of follow-up data also supported the use of EMDR with this population [d = 0.71 (95% CI: 1.04~0.38)]. No publication bias was identified.

CONCLUSIONS

Current evidence suggests that EMDR can be an effective treatment for depression. There were insufficient RCTs on other trauma-focused interventions to conclude whether TFTs in general were effective for treating depression. Larger studies with robust methodology using EMDR and other trauma-focused interventions are needed to build on these findings.

Lost in Transition? Evidence-Based Treatments for Adolescents and Young Adults with Posttraumatic Stress Disorder and Results of an Uncontrolled Feasibility Trial Evaluating Cognitive Processing Therapy

Posttraumatic stress disorder (PTSD) is not uncommon among adolescents and young adults (AYAs). Left untreated, transition to adulthood might be especially challenging and/or prolonged for AYAs. However, it is unclear whether AYAs are adequately represented in current PTSD treatment research and whether they benefit to the same degree as younger or older individuals. In the first part of the paper, we reflect on developmental considerations in the treatment of AYAs and give an overview of current age-specific results in PTSD treatment research. Furthermore, we review individual trauma-focused evidence-based treatments that were examined in AYAs over the last 10 years. In the second part, we present data from an uncontrolled feasibility trial evaluating cognitive processing therapy (CPT) with some age-adapted modifications and an exposure component (written accounts). We treated 17 AYAs (aged 14 to 21) suffering from posttraumatic stress symptoms (PTSS). At posttreatment, participants had improved significantly with respect to clinician-rated PTSS severity (d = 1.32). Treatment gains were maintained throughout the 6-week and 6-month follow-ups. Results indicated that CPT, with only minor adaptations, was feasible and safe in AYAs. The recommendations for future research focus on the inclusion of young adults in trials with adolescents, more refined age reporting in clinical trials, and the encouragement of dismantling studies in youth. To conclude, clinical recommendations for caregiver involvement and the addressing of developmental tasks, motivational issues and emotion regulation problems are discussed.

The Impact of Cognitive-Behavioral Group Psycho-Education Program on Psychological Resilience, Irrational Beliefs, and Well-Being

The aim of this study is to investigate the effect of cognitive-behavioral group psycho-education program on psychological resilience, irrational beliefs, and well-being. In the study, 29 high school students participated. As a data collection, The Resilience Scale, the Irrational Beliefs Scale-Adlescent Form, the Subjective Well-being Scale-High School Form and The Determination of Risk Factors were used. In the study, psycho-education program based on cognitive behavioral approach was applied to experimental group in 10 sessions, once a week. No study was performed with the control group. 2 × 3 experimental design was used in the research. The post-test was administered after the research was completed and follow-up measurements were performed five months later. As a result of the analyzes, it is concluded that there is an increase in psychological resilience levels and a decrease in irrational belief levels of students who participated in psycho-education program based on cognitive behavioral approach. It is concluded that there isn't change in the subjective well-being of the students before and after the application.

Processes of Change in Trauma-Focused Cognitive Behavioral Therapy for Youth: An Emotional Processing Theory Informed Approach

This study examines processes of change in trauma-focused cognitive behavioral therapy (TF-CBT) delivered to a community sample of 81 youth. Emotional processing theory (EPT) is used as an organizational framework. EPT highlights activating and changing pathological trauma-related responses and increasing adaptive responses across cognitive, emotional, behavioral, and physiological domains. We coded sessions during the trauma processing phase of TF-CBT to examine the extent to which pathological and adaptive trauma-related responses were activated across domains. Higher scores indicate that more domains (0-4) were activated at a threshold of moderate to high intensity. Curvilinear change (inverted U, increase then decrease) in multimodal negative response scores across sessions predicted improvement in internalizing and PTSD symptoms at posttreatment. Linear increases in multimodal positive responses predicted improvement in externalizing symptoms. Findings suggest value in activating and changing both pathological and adaptive trauma responses across multiple domains and examining nonlinear patterns of change.

Systematic Review on the Application of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for Preschool-Aged Children

Trauma-focused cognitive behavioral therapy (TF-CBT) is one of the most widely studied and disseminated treatments for posttraumatic stress disorder (PTSD) and other comorbid conditions, and has been identified as a "level one" or "well-established" intervention for school-aged children and adolescents. The present systematic review examined the literature on the application of TF-CBT within a preschool-aged population (i.e., children ages three to six), as well as the developmental literature that could increase the efficacy of TF-CBT for preschool-aged children. Information on the use of TF-CBT with preschool-aged children was extracted from randomized controlled trials, case studies, meta-analyses, and other forms of empirical evidence, as part of the evidence-based practice in psychology framework. In comparison to research with school-aged children and adolescents, fewer studies have directly assessed the efficacy of TF-CBT for preschool-aged children who have been exposed to trauma. Given the few studies published to date and difference in treatment protocols for TF-CBT used with preschool-age children, TF-CBT appears to meet criteria as a "level two" or "probably efficacious" intervention for preschool-aged children specifically. According to the available literature, language and cognitive abilities, family context, culture, and clinician expertise are considered as potential variables to address when contemplating the use of TF-CBT for preschool-aged children with symptoms of post-traumatic stress.

Efficacy and moderators of efficacy of trauma-focused cognitive behavioural therapies in children and adolescents: protocol for an individual participant data meta-analysis from randomised trials

INTRODUCTION

Trauma-focused cognitive behavioural therapies are the first-line treatment for posttraumatic stress disorder (PTSD) in children and adolescents. Nevertheless, open questions remain with respect to efficacy: why does this first-line treatment not work for everyone? For whom does it work best? Individual clinical trials often do not provide sufficient statistical power to examine and substantiate moderating factors. To overcome the issue of limited power, an individual participant data meta-analysis of randomised trials evaluating forms of trauma-focused cognitive behavioural therapy in children and adolescents aged 6-18 years will be conducted.

METHODS AND ANALYSIS

We will update the National Institute for Health and Care Excellence guideline literature search from 2018 with an electronic search in the databases PsycINFO, MEDLINE, Embase, Cochrane Central Register of Controlled Trials and CINAHL with the terms (trauma* OR stress*) AND (cognitive therap* OR psychotherap*) AND (trial* OR review*). Electronic searches will be supplemented by a comprehensive grey literature search in archives and trial registries. Only randomised trials that used any manualised psychological treatment-that is a trauma-focused cognitive behavioural therapy for children and adolescents-will be included. The primary outcome variable will be child-reported posttraumatic stress symptoms (PTSS) post-treatment. Proxy-reports (teacher, parent and caregiver) will be analysed separately. Secondary outcomes will include follow-up assessments of PTSS, PTSD diagnosis and symptoms of comorbid disorders such as depression, anxiety-related and externalising problems. Random-effects models applying restricted maximum likelihood estimation will be used for all analyses. We will use the Revised Cochrane Risk of Bias tool to measure risk of bias.

Complex trauma and Trauma-Focused Cognitive-Behavioral Therapy: How do trauma chronicity and PTSD presentation affect treatment outcome?

BACKGROUND

Traumatic experiences are common in youth and can be classified as acute (one incident or short-term) or complex (chronic exposure to multiple traumas) experiences. Posttraumatic stress disorder (PTSD) is a common response to trauma, often co-occurring with other mental health symptoms. According to the International Classification of Diseases, 11^th Edition (World Health Organization, 2018), complex PTSD includes difficulties with affect regulation, interpersonal relationships, and self-blame.

OBJECTIVE

The aims of this study were to evaluate trauma chronicity and PTSD presentation as moderators of outcomes of trauma-focused cognitive behavior therapy (TF-CBT).

PARTICIPANTS AND SETTING

Participants included 176 youth and caregiver dyads who were participants in an ongoing effectiveness study of TF-CBT at a community-based clinic in NYC.

METHODS

Multilevel modeling was used to examine longitudinal, within-subject variability. Moderation analyses were used to assess the role of trauma chronicity and levels of PTSD on change in the outcomes.

RESULTS

There were no baseline differences between youth with acute versus chronic trauma. At baseline, participants who had PTSD plus 2 or 3 of the ICD-11 Complex PTSD symptom domains had significantly worse functioning than those with simple PTSD. We found significant improvement on most measures of PTSD and complex PTSD domains. Level of improvement was found to vary based on PTSD presentation at baseline.

CONCLUSIONS

This is the first study to evaluate both trauma chronicity and PTSD presentation in the context of evidence-based treatment, and findings support the effectiveness of TF-CBT for simple and complex PTSD for youth who have experienced acute and chronic trauma.

"Like a huge weight lifted off my shoulders": Exploring young peoples' experiences of treatment in a pilot trial of trauma-focused cognitive behavioral therapy

Background: The efficacy of trauma-focused cognitive behavioral therapy (TF-CBT) is well-established, yet little work has been done to understand how young people experience this intervention.Method: Semi-structured interviews were conducted with 13 young people aged 17-25 years (M = 20.0, SD = 2.61) who received TF-CBT as part of a pilot trial. Transcripts were analyzed via interpretative phenomenological analysis.Results: Four super-ordinate themes were identified: (i) experience of authentic care, (ii) personal role in therapy and recovery, (iii) talking about trauma is difficult but important, and (iv), transformative change. Young people described authenticity on behalf of the therapist, which seemed to foster emotional connection and comfort discussing trauma. They emphasized the importance of retaining autonomy and control during therapy, and a degree of personal responsibility in their recovery. Talking about trauma was described as difficult and potentially distressing, but also as critical for recovery. Transformative life changes were noted, which had a significant impact on young peoples' future outlook and self-perception.Conclusions: This study suggests that therapists should be attuned to the interpersonal needs of clients, attempt to foster self-determination throughout therapy, and simultaneously recognize the difficulty and importance of trauma work for young people when delivering TF-CBT.

Traumatic Events Are Associated with Diverse Psychological Symptoms in Typically-Developing Children

Childhood traumatic events are significant risk factors for psychopathology according to adult retrospective research; however, few studies examine trauma exposure and psychological symptoms in pre-adolescent children. Typically-developing children, aged 9-12 years (N = 114), were recruited from the community and selected from the Developmental Chronnecto-Genomics (Dev-CoG) study examining child development. Children completed questionnaires about traumatic life events, posttraumatic stress, anxiety, depression, dissociation, anger, and internalizing and externalizing behaviors. Parents also completed internalizing and externalizing measures. The number of traumatic events significantly correlated with symptom severity across all child-report psychological measures, but surprisingly, trauma was not correlated with any parent-report scores. Follow-up analyses revealed a significant trauma effect for internalizing and externalizing behaviors according to child self-report, but not for parent-report measures. Results indicate that childhood trauma may be a non-specific risk factor for sub-clinical psychopathology in otherwise typically-developing children. Moreover, children appear to be the most appropriate reporters of their own psychological distress.

The Role of Caregiver Psychopathology in the Treatment of Childhood Trauma with Trauma-Focused Cognitive Behavioral Therapy: A Systematic Review

Trauma-focused cognitive behavioral therapy (TF-CBT) is regarded as one of the most effective treatments for children who have experienced trauma and is rapidly being disseminated. To best ensure efficacy, even among treatment refractory symptoms, a better understanding of the factors that lead TF-CBT to be more or less effective for some children is warranted. One major factor that has not been systematically considered is the role of caregiver psychopathology. Therefore, this systematic review of 18 empirical studies examined how TF-CBT has incorporated caregiver psychopathology into the treatment of childhood trauma and how it is related to treatment outcomes. The results of this review provide preliminary support for TF-CBT decreasing caregiver psychopathology, in terms of symptoms of depression, PTSD, and emotional distress related to the child's experience of trauma, as well as partial support for caregiver depression, rather than caregiver PTSD or distress, influencing child treatment outcomes. It also illuminates the strong need for future TF-CBT studies to routinely measure caregiver psychopathology. Several recommendations are provided to ensure that the emerging research base can inform clinical practice guidelines on how to incorporate caregivers who exhibit psychopathology and potentially develop modifications to the existing treatment to address trauma and symptoms in both members of the caregiver-child dyad, when needed.

Comparison of latent typologies of posttraumatic stress disorder and depression symptoms across military personnel from India and the US

Research has identified heterogeneous subgroups of individuals based on posttraumatic stress disorder (PTSD) and depression symptoms. Using data collected from military personnel in India (N = 146) and U.S. (N = 194), we examined (1) the best-fitting latent class solution; (2) multi-group invariance of the class solution; and (3) construct validity of optimal class solution. Results indicated that the optimal 4-class solution differed in severity and severity/type in the India and U.S. samples respectively. With similarity in the optimal number of classes across cultural samples, the meaning/nature of classes differed. In the India sample, anxiety severity predicted the Low Severity Class vs. all other classes, and the Moderately High Severity/High Severity Classes vs. the Moderately Low Severity Class; number of traumas predicted the High Severity Class vs. other classes; and resilience predicted the Moderately Low Severity Class vs. the Moderately High Severity Class. In the U.S. sample, alcohol use predicted the High Severity Class vs. all other classes, and the High Depression-Low PTSD Class vs. the Low Severity Class; rumination significantly predicted the High Severity and High Depression-Low PTSD Classes vs. each of the High PTSD-Low Depression and Low Severity Classes. Thus, meaning and nature of PTSD-depression subgroups may vary culturally; hence, culturally-sensitive interventions need to account for this heterogeneity.

Is There an Ace Up Our Sleeve? A Review of Interventions and Strategies for Addressing Behavioral and Neurobiological Effects of Adverse Childhood Experiences in Youth

Exposure to early life adversity (ELA) is a major public health crisis posing as a significant risk of immediate and sustained mental and physical health consequences. While a remarkable body of knowledge has been amassed showing psychological, cognitive, social, developmental, and neurobiological consequences of ELA exposure, little has been done to improve the long-term mental and physical health outcomes for youth exposed to ELA. Furthermore, neurobiological processes underlying poor outcomes in this population have been largely left out of prevention and intervention target efforts. In this review, we first describe ELA-related alterations across psychological and neurobiological systems in children and adolescents. Next, we describe existing evidence-based interventions targeting ELA-related outcomes. We then turn to experimental studies examining individual differences in mechanistic functioning consequent to ELA exposure, and strategies that target these mechanisms and modulate disrupted functioning. Finally, we highlight areas of future research that may be promising in engaging behavioral and neurobiological targets through novel preventive interventions or augmentation of existing interventions, thereby reducing negative mental and physical health outcomes later in life.

Trauma-focused group intervention for unaccompanied young refugees: "Mein Weg"-predictors of treatment outcomes and sustainability of treatment effects

BACKGROUND

Current research on treatment predictors and long-term effects of trauma-focused interventions for (unaccompanied) refugee minors is limited. This secondary analysis of a recent randomised controlled trial (RCT), evaluating the trauma-focused group intervention "Mein Weg" (English "My Way") compared to usual care, investigated several refugee-specific factors such as treatment predictors and sustainability of treatment gains.

METHODS

In total N = 50 participants (M _age = 17.00, 94% male) were included in this analysis. Evaluation of 3-month follow-up data included: posttraumatic stress symptoms [(PTSS) CATS-Self, CATS-Care], depression (PHQ-8), and dysfunctional posttraumatic cognitions (CPTCI-S). Baseline symptom severity of the above-mentioned measures, trauma load and socio-demographic factors were investigated as the treatment predictors.

RESULTS

Intention-to-treat-analyses (ITT) revealed the sustainability of treatment effects in self-reported PTSS (pre to post change: 6.48 ± 1.60, d = 0.62, p < 0.001; post to 3-month follow-up change: 1.41 ± 1.96, d = 0.11, p = 0.47) and depression (pre to post change: 7.82 ± 2.09, d = 0.64, p < 0.001; post to 3-month follow-up change: 1.35 ± 2.17, d = 0.05, p = 0.54). Country of origin alone was a significant predictor of the change in PTSS (b = - 8.22 ± 3.53, t(30) = - 2.33, p = 0.027), and baseline levels of depression were a significant predictor of the change in depression (b = 0.83 ± 0.19, t(33) = 4.46, p < 0.001).

CONCLUSION

This group intervention can serve as a valuable component in a stepped care approach with promising long-term effects for young refugees.Trial registration DRKS, #DRKS00010915. Registered 15 September 2016, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00010915.

Comparing the Effectiveness of EMDR and TF-CBT for Children and Adolescents: a Meta-Analysis

Efficacy of EMDR and TF-CBT for posttraumatic stress symptoms (PTSS) was explored through meta-analysis. A comprehensive search yielded 494 studies of children and adolescents with PTSS who received treatment with these evidence-based therapeutic modalities. Thirty total studies were included in the meta-analysis. The overall Cohen's d was small (-0.359) and statistically significant (p < 0.05), indicating EMDR and TF-CBT are effective in treating PTSS. Major findings posit TF-CBT is marginally more effective than EMDR; those with sub-clinical PTSS responded more favorably in treatment than those with PTSD; and greater reductions in PTSS were observed with presence of comorbidity in diagnosis. Assessment of publication bias with Classic fail-safe N revealed it would take 457 nonsignificant studies to nullify these findings.

Teaching Recovery Techniques: evaluation of a group intervention for unaccompanied refugee minors with symptoms of PTSD in Sweden

In 2015, a total of 35,369 unaccompanied refugee minors (URMs) sought asylum in Sweden. In a previous study of 208 URMs, we found that 76% screened positive for PTSD. This study aimed to (1) evaluate the indicated prevention program Teaching Recovery Techniques (TRT) in a community setting and describe the program's effects on symptoms of PTSD and depression in URMs; and (2) examine participants' experiences of the program. The study included 10 groups. Methods for evaluation included the Children's Revised Impact of Event Scale (CRIES-8) and the Montgomery-Åsberg Depression Rating Scale Self-report (MADRS-S) at baseline and at post-intervention. Qualitative interviews were conducted with 22 participating URMs to elicit their experiences. Pre- and post-measures were available for 46 participants. At baseline, 83% of the participants reported moderate or severe depression and 48% suicidal ideation or plans. Although more than half (62%) of the participants reported negative life events during the study period, both PTSD (CRIES-8) and depression (MADRS-S) symptoms decreased significantly after the intervention (p = 0.017, 95% CI - 5.55; - 0.58; and p < 0.001, 95% CI - 8.94; - 2.88, respectively). The qualitative content analysis resulted in six overall categories: social support, normalisation, valuable tools, comprehensibility, manageability, and meaningfulness when the youth described their experiences of the program, well reflecting TRT's program theory. Overall, results indicate that TRT, delivered in a community setting, is a promising indicated preventive intervention for URMs with PTSD symptoms. This successful evaluation should be followed up with a controlled study.

Measuring Costs to Community-Based Agencies for Implementation of an Evidence-Based Practice

Healthcare reform has led to an increase in dissemination of evidence-based practices. Cost is frequently cited as a significant yet rarely studied barrier to dissemination of evidence-based practices and the associated improvements in quality of care. This study describes an approach to measuring the incremental, unreimbursed costs in staff time and direct costs to community-based clinics implementing an evidence-based practice through participating in a learning collaborative. Initial implementation costs exceeding those for providing "treatment as usual" were collected for ten clinics implementing trauma-focused cognitive behavioral therapy through participation in 10-month learning collaboratives. Incremental implementation costs of these ten community-based clinic teams averaged the equivalent of US$89,575 (US$ 2012). The most costly activities were training, supervision, preparation time, and implementation team meetings. Recommendations are made for further research on implementation costs, dissemination of evidence-based practices, and implications for researchers and policy makers.

Comparative efficacy and acceptability of psychotherapies for post-traumatic stress disorder in children and adolescents: study protocol for a systematic review and network meta-analysis

INTRODUCTION

Post-traumatic stress disorder (PTSD) is common among children and adolescents who are exposed to trauma, and it is often associated with significant negative impacts on their psychosocial functioning and quality of life. Many types of psychotherapies have been found to be effective for PTSD in children and adolescents. However, due to the lack of direct comparisons between different psychotherapies, the hierarchy of treatment efficacy is still unclear. Therefore, we plan to conduct a systematic review and network meta-analysis to evaluate the efficacy and acceptability of various types of psychotherapies for PTSD in children and adolescents.

METHODS AND ANALYSIS

A systematic search will be conducted among eight electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, Cumulative Index of Nursing and Allied Health, Published International Literature on Traumatic Stress (PILOTS) and ProQuest Dissertations, from inception to October 2017. Randomised controlled trials, regardless of language, publication year and publication type, comparing any psychotherapies for PTSD to any control condition or alternative treatment in children and adolescents (18 years old or less) diagnosed with full or subclinical PTSD will be included. Study duration and the number of treatment sessions will not be limited. The primary outcome will be PTSD symptom severity at post-treatment as measured by a rating scale reported by the child, parent or a clinician. The secondary outcomes will include: (1) efficacy at follow-up; (2) acceptability (all-cause discontinuation); (3) anxiety symptom severity; (4) depressive symptom severity and (5) quality of life and functional improvement. Bayesian network meta-analyses for all relative outcome measures will be performed. We will conduct subgroup and sensitivity network meta-analyses to determine whether the findings are affected by study characteristics. The quality of the evidence contributing to network estimates of the primary outcome will be evaluated by the Grading of Recommendations, Assessment, Development and Evaluations framework.

ETHICS AND DISSEMINATION

No ethical issues are foreseen. The results will be published in a peer-reviewed journal, which will be disseminated electronically and in print. This network meta-analysis may be updated to inform and guide the clinical management of PTSD in children and adolescents.

Intensive prolonged exposure treatment for adolescent complex posttraumatic stress disorder: a single-trial design

BACKGROUND

The current study evaluated the effectiveness and safety of intensive prolonged exposure (PE) targeting adolescent patients with complex posttraumatic stress disorder (PTSD) and comorbid disorders following multiple interpersonal trauma.

METHODS

Ten adolescents meeting full diagnostic criteria for PTSD were recruited from a specialized outpatient mental health clinic and offered a standardized intensive PE. The intensive PE consisted of three daily 90-min exposure sessions delivered on five consecutive weekdays, followed by 3 weekly 90-min booster sessions. In a single-trial design, the participants were randomly allocated to one of five baseline lengths (4-8 weeks) before starting the intensive PE. Before, during, and after intensive PE completion, self-reported PTSD symptom severity was assessed weekly as a primary outcome (a total of 21 measurements). Furthermore, clinician-administered PTSD diagnostic status and symptom severity (primary outcome), as well as self-reported comorbid symptoms (secondary outcomes), were assessed at four single time points (baseline-to-6-month follow-up).

RESULTS

Time-series analyses showed that self-reported PTSD symptom severity significantly declined following treatment (p = .002). Pre-postgroup analyses demonstrated significant reductions of clinician-administered PTSD symptom severity and self-reported comorbidity that persisted during the 3- and 6-month follow-ups (all ps < .05), where 80% of adolescents had reached diagnostic remission of PTSD. There was neither treatment dropout nor any adverse events.

CONCLUSIONS

The results of this first proof of concept trial suggest that intensive PE can be effective and safe in an adolescent population with complex PTSD, although the gains achieved need to be confirmed in a randomized controlled trial.

Efficacy of cognitive-behavioral therapy for childhood anxiety and depression

A review of meta-analyses of cognitive-behavioral therapy (CBT) for childhood anxiety and depression was conducted. A total of 36 meta-analyses were identified that met inclusion criteria for this review. In most cases, medium-to-large effect sizes for treatment reduction were observed when CBT was compared to non-active control conditions. Small-to-medium effects were observed when CBT was compared to active control treatments. The available meta-analyses generally did not examine, or data were not sufficient to evaluate, potential moderators of outcome, differential effects for parental involvement, or changes in quality of life or functional outcomes associated with treatment. Accordingly, while CBT should be broadly considered an effective treatment approach for childhood anxiety and depression, additional research is warranted in order to establish guidelines for service delivery for complicating factors in client presentation.

Interventions for posttraumatic stress disorder: a review of the evidence base

Given high rates of trauma exposure in South Africa, mental health practitioners often need to deliver interventions to trauma survivors. While there have been few local trauma intervention studies, there is an extensive international evidence base that provides a rich resource on which to draw. This article reviews evidence-based treatments for posttraumatic stress disorder and complex posttraumatic stress disorder. The current weight of evidence supports the use of trauma-focused cognitive behavioural therapy approaches in the treatment of posttraumatic stress disorder and the use of multimodal, phase-based interventions to treat complex posttraumatic stress disorder. There is also a long-standing, though less extensive, evidence base for psychodynamic therapy in the treatment of these conditions, as well as a number of emerging treatment approaches that require further study. While there are some limitations to transferring these approaches to the South African context, the current evidence base provides valuable guidelines for local practitioners seeking to develop their competencies in treating posttraumatic stress disorder and more complex trauma-based presentations.
