Treating Children and Adolescents with Posttraumatic Stress Disorder: Moderators of Treatment Response

Effectiveness of an intensive outpatient treatment programme combining prolonged exposure and EMDR therapy for adolescents and young adults with PTSD in a naturalistic setting

Background: Psychotherapeutic interventions aimed at treating posttraumatic stress disorder (PTSD) in adolescents and young adults are hampered by high dropout rates. Looking at the results from adult treatments, short, intensive, outpatient treatment programmes may offer a promising alternative, but it has yet to be tested in this young population.Objective: To assess the results of a six-day intensive outpatient trauma-focused treatment programme for young individuals (12-25 years) with PTSD. The treatment combined prolonged exposure and EMDR therapy, supplemented with physical activity and the participation of relatives and/or friends. Treatment was performed by a rotating team of therapists.Methods: Seventy-four adolescents and young adults (89% women, mean age = 18.6 years, 36 patients aged 12-17 and 38 patients aged 18-25; SD = 3.1) with PTSD and a minimum of four memories of A-criterion traumatic events participated in the programme. PTSD symptoms, depressive symptoms, and the perceived burden of trauma symptoms were assessed before treatment, at the start and one month after treatment.Results: Patients showed a significant reduction in PTSD symptoms from pre-treatment to one month after treatment (Cohen's d = 1.66). Of all patients, 52 (70%) showed a clinically meaningful response, and 48 (65%) no longer met the diagnostic criteria for PTSD one month after treatment. Depressive symptoms also decreased significantly (Cohen's d = 1.02). The dropout rate was 4% (N = 3). None of the patients experienced an adverse event or worsening of symptoms.Conclusions: Results suggest that a short, intensive, outpatient therapy programme combining prolonged exposure, EMDR therapy, physical activity, and participation of relatives and friends, is well-tolerated, and an effective and safe treatment alternative for adolescents and young adults with PTSD due to multiple traumatization.

Family therapy and EMDR after child abuse and neglect: moderating effects of child attachment style and PTSD symptoms on treatment outcome

Background: Effective and appropriate care and treatment for children in order to decrease the psychosocial problems that arose after experiencing child abuse and neglect (CAN) is of vital importance, given the severity of symptomatology that may develop.Objective: The purpose of the present study was to examine whether attachment style and core cluster Posttraumatic Stress Disorder symptoms acted as moderators for treatment outcomes of a new integrative treatment model for trauma and attachment. In this treatment model, family therapy is combined with EMDR and obstacles for trauma processing are tackled first.Method: we included children, ages 6-12 years, with a history of CAN, who did not respond to evidence-based trauma treatment. Target treatment outcomes were problems in attachment, posttraumatic stress symptoms, behaviour, and emotion regulation. We conducted a multiple-baseline ABC Single-Case Experimental Design (SCED). We categorized 12 participants into four groups of attachment style and core cluster PTSD symptoms: (1) non-disorganized & re-experiencing; (2) non-disorganized & avoidance/hyperarousal; (3) disorganized & re-experiencing; & (4) disorganized & avoidance/hyperarousal. We compared the four groups with each other and across time, and the interaction between groups and effect over time. We conducted non-parametric permutation tests and estimated q-values for false discovery rate control.Results: Children with a disorganized attachment style had more severe symptomatology in general, except for posttraumatic stress symptoms. The treatment appeared more effective in targeting and successfully treating children with a non-disorganized attachment style, and specifically children with a non-disorganized attachment style and re-experiencing as core cluster PTSD symptoms.Conclusion: Our study underlines the complexity of treating children who developed a complicated combination of symptomatology after CAN and calls for the continuous development of innovative interventions.

Differences of TF-CBT treatment effects using various outcome measures: a meta-analysis

Background: Diagnostic criteria of posttraumatic stress disorder in children and adolescents and corresponding instruments have undergone significant changes over time. However, the impact of different outcome measures on treatment effects in the context of posttraumatic stress symptoms (PTSS) has not yet been explored.Objective: TF-CBT is a well-researched first-line treatment for PTSS among children and adolescents and thus, an ideal candidate to examine the potential influence of different outcome measures by meta-analysis.Method: A comprehensive literature search was conducted in December 2023 using seven databases. Studies included RCTs as well as non-controlled studies examining the effects of TF-CBT on pediatric PTSS. We extracted treatment effects and investigated whether there were systematic differences in the effects based on the outcome measures and their underlying DSM version.Results: In total, 76 studies (35 RCTS) met the eligibility criteria. Hedges g effect sizes with 95% confidence intervals (CI) were computed and high-risk of bias studies were excluded. No significant difference was observed between DSM-IV and DSM-5 based instruments. Individual outcome measures were found to be comparable overall, with some appearing somewhat more sensitive to change. Although a small but significant difference in true effect sizes for individual outcome measures was found, this only concerned the UCLA PTSD (g = 1.06) and the CPSS (g = 1.61) with the effect most likely being due to chance or confounding variables. TF-CBT showed large effect sizes on PTSS in within-study comparison (g = 1.32) and medium between-studies effect sizes (g = .57).Conclusions: While we could not establish equivalence, there seems to be no difference regarding the measurement of treatment effects based on outcome measure and underlying DSM version. The updated TF-CBT effect size confirmed it as an effective treatment for PTSS and secondary outcomes in children and adolescents.

Psychological Interventions for Post-traumatic Stress Disorder as a Primary Diagnosis Among Adolescents: A Meta-analysis

Purpose

The objective of this study was to do a meta-analysis focusing on the efficacy of psychological intervention for the adolescent population and PTSD as a primary outcome variable.

Collection and Analysis of Data

An electronic search was conducted on PubMed, Science Direct, PsycINFO, and Cochrane Library databases from January 1, 1990, to March 31, 2023. Original studies and systematic reviews/meta-analyses were segregated. In the first study, 129 meta-analyses (MAs) were screened and 8 MAs were analyzed. In the second study, six RCTs and five non-RCTs exclusively including adolescents with a primary diagnosis of PTSD were analyzed. The MA revealed the average sample size to be 243.33 (SD = 372.94) with 63.98% female participants in RCTs and 153 (SD = 237.17) with 56.99% female participants in non-RCTs. A total of 13 different interventions were analyzed. Cognitive-behavioral intervention had a large effect size of 1.63 for PTSD. Cochrane's Q test and I2 index revealed considerable heterogeneity among groups. There was no significant difference between RCTs and non-RCTs in the total number and duration of intervention sessions and the duration of each session. However, the average follow-up time points varied significantly between RCTs and non-RCTs. RCTs followed random sequence generation and, hence, had a low risk of selection bias.

Conclusion

Although the CBT framework with a focus on trauma and traumatic emotions was at the core of treatment efficacy, the type of trauma was the key consideration. Further studies of treatment efficacy moderated by specific trauma characteristics are required to advance the knowledge base in the treatment of PTSD in adolescents.

Are Differences Evident in the Ways Boys and Girls Appraise and Interpret Their Traumatic Experiences? A Qualitative Analysis of Youth Trauma Narratives

The purpose of this study was to explore potential similarities and differences in the ways boys and girls appraise and interpret their traumatic experiences, and better understand how gender roles, performance, and socialization processes may impact trauma experiences, appraisals, and narratives within the context of trauma-focused treatment. We used thematic analysis to analyze the trauma narratives of youth (N = 16) ages 8-16 who had experienced multiple types (M = 5.38) of child maltreatment and who were receiving Trauma-focused Cognitive Behavioral Therapy to address clinically elevated posttraumatic stress symptoms. Four themes emerged: variations in the content of negative cognitions, differences in relational emotion, adoption of socially prescribed gender roles, and symptom differences. Although many similarities existed in youth's trauma narratives, differences emerged that point to the importance of social context and the ways gender role expectations and socialization processes influence youth's appraisal of and responses to traumatic events. Findings indicate the importance of considering distress tolerance, relational emotion, gender identity development, and role socialization within the treatment milieu.

Clinical Efficacy of Psychotherapeutic Interventions for Post-Traumatic Stress Disorder in Children and Adolescents: A Systematic Review and Analysis

Background: This systematic review aggregates research on psychotherapeutic interventions for Post-Traumatic Stress Disorder (PTSD) in children and adolescents. PTSD in this demographic presents differently from adults, necessitating tailored therapeutic approaches. In children and adolescents, PTSD arises from exposure to severe danger, interpersonal violence, or abuse, leading to significant behavioral and emotional disturbances that jeopardize long-term development. The review focuses on describing PTSD within two age groups, children (6 to 12 years) and adolescents (12 to 18 years), while evaluating the effectiveness of various clinical interventions aimed at this condition. Methods: Utilizing the PRISMA guidelines, this review systematically examines studies that assess clinical interventions for PTSD in the younger population. Results: Key symptoms of PTSD in children and adolescents include avoidance, overstimulation, flashbacks, depression, and anxiety. The review identifies several effective treatments, including Cognitive Behavioral Therapy (CBT), Trauma-Focused CBT (TF-CBT), Eye Movement Desensitization and Reprocessing (EMDR), Systemic Therapy, Play Therapy, Exposure Therapy, Relaxation Techniques, and Psychodynamic Psychotherapy. Particularly, TF-CBT is highlighted as the most effective and commonly used method in treating childhood and adolescent PTSD, as supported by most of the studies reviewed. Conclusions: A significant outcome of this study is the short-term effectiveness of CBT in reducing PTSD symptoms in children and adolescents. The findings underline the importance of psychotherapeutic interventions and mark a substantial advancement in understanding PTSD in young populations. It is crucial for practitioners to integrate various psychotherapeutic strategies into their practice to improve patient outcomes and treatment efficacy.

The bidirectional associations between caregiver and child symptoms in the parent-led treatment stepping together for children after trauma

BACKGROUND

An innovative approach to child trauma treatment in which caregivers are allocated treatment tasks has shown promising results, but less is known about the bidirectional associations between caregiver and child symptoms during treatment.

METHODS

Eighty-two child-caregiver dyads who participated in the parent-led therapist-assisted Stepping Together for Children after Trauma (ST-CT) were included (child age: 7-12 years, mean = 9.9 years). Caregivers' emotional reactions and anxiety/depression and children's posttraumatic stress (PTS) and depression were assessed pretreatment, mid-treatment, and posttreatment. We investigated the possible directional associations between caregivers' emotional reactions and anxiety/depression and children's PTS and depression using random intercept cross-lagged panel models.

RESULTS

Symptoms improved in both caregivers and children. Lower levels of caregiver emotional reactions at pretreatment predicted improved child PTS at mid-treatment; lower levels of caregiver emotional reactions at mid-treatment predicted improved child depression at posttreatment; and lower levels of child PTS at mid-treatment predicted improved caregiver emotional reactions at posttreatment.

CONCLUSIONS

These findings suggest that caregivers and children can impact each other's responses to a parent-led child trauma-focused treatment. Notably, children with caregivers who were less affected by their own emotional reactions exhibited greater improvement in both PTS and depression. Supporting the caregivers may benefit both children and caregivers.

Food4healthKG: Knowledge graphs for food recommendations based on gut microbiota and mental health

Food is increasingly acknowledged as a powerful means to promote and maintain mental health. The introduction of the gut-brain axis has been instrumental in understanding the impact of food on mental health. It is widely reported that food can significantly influence gut microbiota metabolism, thereby playing a pivotal role in maintaining mental health. However, the vast amount of heterogeneous data published in recent research lacks systematic integration and application development. To remedy this, we construct a comprehensive knowledge graph, named Food4healthKG, focusing on food, gut microbiota, and mental diseases. The constructed workflow includes the integration of numerous heterogeneous data, entity linking to a normalized format, and the well-designed representation of the acquired knowledge. To illustrate the availability of Food4healthKG, we design two case studies: the knowledge query and the food recommendation based on Food4healthKG. Furthermore, we propose two evaluation methods to validate the quality of the results obtained from Food4healthKG. The results demonstrate the system's effectiveness in practical applications, particularly in providing convincing food recommendations based on gut microbiota and mental health. Food4healthKG is accessible at https://github.com/ccszbd/Food4healthKG.

Development and Implementation of DIALOG+S in the School Setting as a Tool for Promoting Adolescent Mental Well-Being and Resilience in a Post-Armed Conflict Area in Colombia: Exploratory Cluster Randomized Controlled Trial

BACKGROUND

Educational settings are ideal for promoting mental well-being and resilience in children. The challenges of the COVID-19 pandemic made evident the important role that teachers and school counselors play in the mental health of their students. Therefore, it is imperative to develop and implement cost-effective interventions that allow them to identify and address mental health problems early, especially in post-armed conflict areas, to reduce the burden of mental disorders in this population.

OBJECTIVE

This study aimed to adapt an existing patient-focused digital intervention called DIALOG+ from an adult clinical setting to an adolescent educational setting and to assess the feasibility, acceptability, and estimated effect of implementing this intervention as a tool for promoting quality of life, mental well-being, and resilience.

METHODS

We conducted an exploratory mixed methods study in 2 public schools in postconflict areas in Tolima, Colombia. This study was conducted in 3 phases. In the adaptation phase, focus groups were conducted with students and teachers to identify changes required in DIALOG+ for it to be used in the school setting. The exploration phase consisted of an exploratory cluster randomized controlled trial. A total of 14 clusters, each with 1 teacher and 5 students, were randomly allocated to either the experimental (DIALOG+S) group or to an active control group (counseling as usual). Teachers in both groups delivered the intervention once a month for 6 months. Through screening scales, information was collected on mental health symptoms, quality of life, self-esteem, resilience, and family functionality before and after the intervention. Finally, the consolidation phase explored the experiences of teachers and students with DIALOG+S using focus group discussions.

RESULTS

The changes suggested by participants in the adaptation phase highlighted the central importance of the school setting in the mental health of adolescents. In the exploratory phase, 70 participants with a mean age of 14.69 (SD 2.13) years were included. Changes observed in the screening scale scores of the intervention group suggest that the DIALOG+S intervention has the potential to improve aspects of mental health, especially quality of life, resilience, and emotional symptoms. The consolidation phase showed that stakeholders felt that using this intervention in the school setting was feasible, acceptable, and an enriching experience that generated changes in the perceived mental health and behavior of participants.

CONCLUSIONS

Our results are encouraging and show that the DIALOG+S intervention is feasible and acceptable as a promising opportunity to promote well-being and prevent and identify mental health problems in the school context in a postconflict area in Colombia. Larger, fully powered studies are warranted to properly assess the efficacy and potential impact of the intervention and to refine implementation plans.

Sex-specific immune mechanisms in PTSD symptomatology and risk: A translational overview and perspectives

Altered immune function in patients with posttraumatic stress disorder (PTSD) may play a role in the disorder pathophysiology and onset. Women are more likely to develop PTSD, suggesting potential sex-specific inflammatory mechanisms underlying the dichotomous prevalence and risk of PTSD in men and women. In this review we examine the available literature to better assess the state of knowledge in the field. In humans, increased systemic inflammation is found in both men and women with PTSD, but seems to be at a greater extend in women. Despite the existence of few clinical studies taking account of sex as a factor in the observed immune changes in PTSD, challenges in the study of sex-specific immune function in humans include: controlling for confounding variates such as the type of trauma and the ethnicity; and limited methodologies available to study central nervous system (CNS)-relevant changes. Thus, preclinical studies are a valuable tool to provide us with key insights on sex-specific peripheral and CNS immune mechanisms underlying PTSD. Available preclinical studies reported increased systemic and CNS inflammation, as well as elevated trafficking of monocytes from the periphery to the brain in both male and female rodents. To date, psychological trauma-induced inflammation is more robust in female vs male rodents. Limitations of preclinical studies include animal models hardly applicable to female rodents, and hormonal changes across estrus phases that may affect immune function. The present review: (1) highlights the key findings from both human and animal studies, (2) provides guidance to address limitations; and (3) discusses the gap of knowledge on the complex intertwined interaction between the brain, neurovascular, and systemic units.

Child Traumatic Stress and COVID-19: The Impact of the Pandemic on a Clinical Sample of Children in Trauma Treatment

Given the scope and duration of the COVID-19 pandemic, it is not surprising that research has documented negative effects to youth's mental health. Yet, there is negligible research on the impact of the pandemic among clinical samples of youth receiving treatment for pre-existing trauma exposure and symptoms. The current study investigates COVID-19 as an index trauma, and if prior traumatic stress scores mediate the relationship between pandemic-related exposure and subsequent traumatic stress.

METHODS

This is a study of 130 youth ages 7-18 receiving trauma treatment at an academic medical center. The University of California Los Angeles Post-traumatic Stress Disorder-Reaction Index (UCLA-PTSD-RI) was completed by all youth during intake as part of routine data collection. From April, 2020 to March, 2022 the UCLA Brief COVID-19 Screen for Child/Adolescent PTSD was also administered to assess trauma exposures and symptoms specifically-related to the pandemic experience. Univariate and bivariate analyses were conducted on all variables of interest to describe response patterns cross-sectionally and longitudinally; a mediational analysis was used to determine if prior trauma symptoms mediate the relationship between COVID-19 exposure and response. Additionally, interviews were conducted with youth using a series of open-ended questions about their perceptions of safety, threat and coping related to the pandemic.

RESULTS

A quarter of the sample reported COVID-19 related exposures that would meet Criterion A for PTSD. Participants whose UCLA-COVID scores that exceeded the clinical cutoff had lower scores on two items measuring social support. There was no evidence of full or partial mediation. Responses to interview questions revealed low levels of threat reactivity, perceptions of no to little impact, positive changes, varying opinions on social isolation, some evidence of inaccurate messaging and adaptive coping using strategies learned in treatment.

IMPLICATIONS

The findings broaden our understanding of the impact of COVID-19 on vulnerable children and provide insight into how prior trauma history and the provision of evidence-based trauma treatment impact a youth's response to pandemic conditions.

Parent-led stepped care for traumatised children: parental factors that predict treatment completion and response

Background: Stepped care cognitive behavioural therapy for children after trauma (SC-CBT-CT; aged 7-12 years) can help to increase access to evidence-based trauma treatments for children. SC-CBT-CT consists of a parent-led therapist-assisted component (Step One) with an option to step up to standard therapist-led treatment (Step Two). Studies have shown that SC-CBT-CT is effective; however, less is known about what parent variables are associated with outcome of Step One.Objective: To examine parent factors and their relationship with completion and response among children receiving Step One.Method: Children (n = 82) aged 7-12 (M = 9.91) received Step One delivered by their parents (n = 82) under the guidance of SC-CBT-CT therapists. Logistic regression analyses were used to investigate whether the following factors were associated with non-completion or non-response: the parents' sociodemographic variables, anxiety and depression, stressful life experiences and post-traumatic symptoms, negative emotional reactions to their children's trauma, parenting stress, lower perceived social support, and practical barriers to treatment at baseline.Results: Lower level of educational achievement among parents was related to non-completion. Higher levels of emotional reactions to their child's trauma and greater perceived social support were related to non-response.Conclusions: The children seemed to profit from the parent-led Step One despite their parents` mental health challenges, stress, and practical barriers. The association between greater perceived social support and non-response was unexpected and warrants further investigation. To further increase treatment completion and response rates among children, parents with lower education may need more assistance on how to perform the interventions, while parents who are very upset about their child's trauma may need more emotional support and assurance from the therapist.Trial registration: ClinicalTrials.gov NCT04073862; https://clinicaltrials.gov/ct2/show/NCT04073862. Retrospectively registered 03 June 2019 (first patient recruited May 2019).

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.

Embracing Scientific Humility and Complexity: Learning "What Works for Whom" in Youth Psychotherapy Research

Clinical psychological scientists have spent decades attempting to understand "what works for whom" in the context of youth psychotherapy, toward the longstanding goal of personalizing psychosocial interventions to fit individual needs and characteristics. However, as the articles in this Special Issue jointly underscore, more than 50 years of psychotherapy research has yet to help us realize this goal. In this introduction to the special issue, we outline how and why "aspiration-method mismatches" have hampered progress toward identifying moderators of youth psychotherapy; emphasize the need to embrace etiological complexity and scientific humility in pursuing new methodological solutions and propose individual and structural strategies for better-aligning clinical research methods with the goal of personalizing mental health care for youth with diverse identities and treatment needs.

Predictors and moderators of treatment outcome for single incident paediatric PTSD: a multi-centre randomized clinical trial

BACKGROUND

With few RCTs having compared active treatments for paediatric PTSD, little is known about whether or which baseline (i.e. pre-randomization) variables predict or moderate outcomes in the evaluated treatments.

OBJECTIVE

To identify predictors and moderators of paediatric PTSD outcomes for Eye Movement Desensitization and Reprocessing Therapy (EMDR) and Cognitive Behavioural Writing Therapy (CBWT).

METHOD

Data were obtained as part of a multi-centre, randomized controlled trial of up to six sessions (up to 45 minutes each) of either EMDR therapy, CBWT, or wait-list, involving 101 youth (aged 8-18 years) with a PTSD diagnosis (full/subthreshold) tied to a single event. The predictive and moderating effects of the child's baseline sociodemographic and clinical characteristics, and parent's psychopathology were evaluated using linear mixed models (LMM) from pre- to post-treatment and from pre- to 3- and 12-month follow-ups.

RESULTS

At post-treatment and 3-month follow-up, youth with an index trauma of sexual abuse, severe symptoms of PTSD, anxiety, depression, more comorbid disorders, negative posttraumatic beliefs, and with a parent with more severe psychopathology fared worse in both treatments. For children with more severe self-reported PTSD symptoms at baseline, the (exploratory) moderator analysis showed that the EMDR group improved more than the CBWT group, with the opposite being true for children and parents with a less severe clinical profile.

CONCLUSIONS

The most consistent finding from the predictor analyses was that parental symptomatology predicted poorer outcomes, suggesting that parents should be assessed, supported and referred for their own treatment where indicated. The effect of the significant moderator variables was time-limited, and given the large response rate (>90%) and brevity (<4 hours) of both treatments, the present findings suggest a focus on implementation and dissemination, rather than tailoring, of evidence-based trauma-focused treatments for paediatric PTSD tied to a single event.
