Practitioner Review: Posttraumatic stress disorder and its treatment in children and adolescents

Loneliness and posttraumatic stress in U.S. adolescents: A longitudinal study

BACKGROUND

Loneliness and posttraumatic stress (PTS) are common in adolescence. However, there has been little longitudinal research on their association. To address this deficit, this study examined the longitudinal association between these phenomena in a sample of U.S. school students while also exploring if gender was important in this context.

METHODS

Data were analysed from 2807 adolescents (52.1 % female; age at baseline 11-16 years (M = 12.79)) who were followed over a one-year period. Information was obtained on loneliness in year 1 using a single-item question, while PTS was assessed with the self-report Child Post-Traumatic Stress - Reaction Index (CPTS-RI). A full path analysis was performed to assess the across time associations.

RESULTS

Almost one-third of the students reported some degree of loneliness while most students had 'mild' PTS. In the path analysis, when controlling for baseline PTS and other covariates, loneliness in year 1 was significantly associated with PTS in year 2 (β = 0.06, 95%CI: 0.02, 0.09). Similarly, PTS in year 1 was significantly associated with loneliness in year 2 (β = 0.19, 95%CI: 0.15, 0.23). An interaction analysis further showed that loneliness was higher in girls with PTS than in their male counterparts.

LIMITATIONS

The use of a single-item measure to assess loneliness that used the word 'lonely' may have resulted in underreporting.

CONCLUSION

Loneliness and PTS are bidirectionally associated in adolescence. Efforts to reduce loneliness in adolescence may help in combatting PTS, while clinicians should intervene to address loneliness if detected in adolescents with PTS.

Healthcare resource utilisation and suicidal ideation amongst adolescents in the US with posttraumatic stress disorder, major depressive disorder, and substance use disorders using electronic health records

BACKGROUND

While PTSD is commonly associated with multiple comorbidities, studies have yet to quantify the impact of these comorbidities on key clinical outcomes and HCRU. This study explored risks of emergency room (ER) visits, inpatient admissions (IA), suicidal ideation (SI), and treatment follow-up duration (FU), amongst PTSD patients with comorbid MDD and/or SUD.

METHODS

Using real-world data (RWD) generated by electronic health records accessed from the NeuroBlu database, a cohort of adolescent patients (12-17 yrs) was examined over a one-year study period following PTSD diagnosis.

RESULTS

5794 patients were included in the cohort. Compared to patients with only PTSD (n = 3061), those with comorbid MDD (n = 1820) had greater odds of ER (4.5 times), IA (1.6 times), and FU (4.3 times). Those with comorbid SUD (n = 653) had greater odds of IA (4.5 times), shorter FU (34 days), and lower odds of ER (0.5 times). Both comorbidities (n = 260) had greater odds of ER (3.8 times), IA (2.6 times), SI (3.6 times), and shorter FU (12 days).

LIMITATIONS

These RWD had a high proportion of missingness. Health records of patients who changed service providers could not be accounted for in this study.

CONCLUSIONS

Both MDD and SUD substantially elevated the risk of HCRU and suicidal ideation for PTSD patients.

COULD FAMILY WELL-BEING MODERATE THE RELATIONSHIP BETWEEN ADVERSE CHILDHOOD EXPERIENCES AND SOMATOFORM DISSOCIATION? A PRELIMINARY INVESTIGATION

The impacts of adverse childhood experiences (ACEs) have been well documented. One possible consequence of ACEs is dissociation, which is a major feature of post-traumatic psychopathology and is also associated with considerable impairment and health care costs. Although ACEs are known to be associated with both psychoform and somatoform dissociation, much less is known about the mechanisms behind this relationship. Little is known about whether social and interpersonal factors such as family environments would moderate the relationship between ACEs and somatoform dissociation. This paper discusses the importance of having a positive and healthy family environment in trauma recovery. We then report the findings of a preliminary study in which we examined whether the association between ACEs and somatoform dissociation would be moderated by family well-being in a convenience sample of Hong Kong adults (N = 359). The number of ACEs was positively associated with somatoform dissociative symptoms, but this association was moderated by the level of family well-being. The number of ACEs was associated with somatoform dissociation only when the family well-being scores were low. These moderating effects were medium. The findings point to the potential importance of using family education and intervention programs to prevent and treat trauma-related dissociative symptoms, but further investigation is needed.

Practitioner Review: Neurobiological consequences of childhood maltreatment - clinical and therapeutic implications for practitioners

BACKGROUND

Childhood maltreatment is one of the most important preventable risk factors for a wide variety of psychiatric disorders. Further, when psychiatric disorders emerge in maltreated individuals they typically do so at younger ages, with greater severity, more psychiatric comorbid conditions, and poorer response to established treatments, resulting in a more pernicious course with an increased risk for suicide. Practitioners treating children, adolescents, and young adults with psychiatric disorders will likely encounter the highest prevalence of clients with early-onset maltreatment-associated psychiatric disorders. These may be some of their most challenging cases.

METHOD

In this report, we explore key validated alterations in brain structure, function, and connectivity associated with exposure to childhood maltreatment as potential mechanisms behind their patients' clinical presentations.

RESULTS

We then summarize key behavioral presentations likely associated with neurobiological alterations and propose a toolkit of established trauma and skills-based strategies that may help diminish symptoms and foster recovery. We also discuss how some of these alterations may serve as latent vulnerability factors for the possible development of future psychopathology.

CONCLUSIONS

Research on the neurobiological consequences of childhood adversity provides a vastly enriched biopsychosocial understanding of the developmental origins of health and pathology that will hopefully lead to fundamental advances in clinical psychology and psychiatry.

Internet- and mobile-based psychological interventions for post-traumatic stress symptoms in youth: a systematic review and meta-analysis

Psychological interventions can help reduce posttraumatic stress symptoms (PTSS) in youth, but many do not seek help. Internet- and mobile-based interventions (IMIs) show promise in expanding treatment options. However, the overall evidence on IMIs in reducing PTSS among youth remains unclear. This systematic review and meta-analysis investigated the efficacy of IMIs in PTSS reduction for youth exposed to traumatic events. A comprehensive literature search was conducted in January 2023 including non-randomized and randomized-controlled trials (RCT) investigating the effects of IMIs on PTSS in youth aged ≤25 years. Six studies were identified with five providing data for the meta-analysis. The majority of studies included youth with different types of trauma irrespective of PTSS severity at baseline (k = 5). We found a small within-group effect in reducing PTSS from baseline to post-treatment (g = -0.39, 95% CrI: -0.67 to -0.11, k = 5; n = 558; 9 comparisons). No effect emerged when comparing the effect of IMIs to control conditions (g = 0.04; 95%-CrI: -0.52 to 0.6, k = 3; n = 768; k = 3; 4 comparisons). Heterogeneity was low between and within studies. All studies showed at least some concerns in terms of risk of bias. Current evidence does not conclusively support the overall efficacy of IMIs in addressing youth PTSS. This review revealed a scarcity of studies investigating IMIs for youth exposed to traumatic events, with most being feasibility studies rather than adequately powered RCTs and lacking a trauma focus. This underscores the demand for more high-quality research.

'Life should go on': a qualitative inquiry of parental reactions, experiences, and perceived needs following adolescents' recent traumatic exposure

Background: Parents have a significant role in supporting children who have been exposed to traumatic events. Little is known about parental experiences and needs in the wake of traumatic exposure, which could help in designing tailored early interventions.Objective: This qualitative study explored experiences, perceived needs, and factors impacting those needs being met, in parents of adolescents aged 11-16 years who had been exposed in the past 3 months to a potentially traumatic event, in the city of Montpellier, France.Method: We purposively sampled 34 parents of 25 adolescents aged 11-16 years meeting the inclusion criteria and used semi-structured in-depth interviews. Thematic analysis was applied using a multistage recursive coding process.Results: Parents lacked trauma-informed explanations to make sense of their child's reduced functioning. They experienced stigma attached to the victim label and were reluctant to seek help. School avoidance and lack of collaboration with schools were major obstacles experienced by parents. Parents trying to navigate conflicting needs fell into two distinct categories. Those who experienced distressing levels of shame and guilt tended to avoid discussing the traumatic event with their child, pressuring them to resume life as it was before, despite this perpetuating conflictual interactions. Others adapted by revisiting their beliefs that life should go on as it was before and by trying to come up with new functional routines, which improved their relationship with their child and helped them to restore a sense of agency and hope, but at the cost of questioning their parental role.Conclusions: Key domains of parental experiences could provide potential early intervention targets, such as psychoeducation on traumatic stress, representations about recovery and the victim status, parent-child communication, and involvement of schools and primary caregivers. Further research is needed to validate the impact of these domains in early post-traumatic interventions.

Efficacy and moderators of efficacy of cognitive behavioural therapies with a trauma focus in children and adolescents: an individual participant data meta-analysis of randomised trials

BACKGROUND

Existing clinical trials of cognitive behavioural therapies with a trauma focus (CBTs-TF) are underpowered to examine key variables that might moderate treatment effects. We aimed to determine the efficacy of CBTs-TF for young people, relative to passive and active control conditions, and elucidate putative individual-level and treatment-level moderators.

METHODS

This was an individual participant data meta-analysis of published and unpublished randomised studies in young people aged 6-18 years exposed to trauma. We included studies identified by the latest UK National Institute of Health and Care Excellence guidelines (completed on Jan 29, 2018) and updated their search. The search strategy included database searches restricted to publications between Jan 1, 2018, and Nov 12, 2019; grey literature search of trial registries ClinicalTrials.gov and ISRCTN; preprint archives PsyArXiv and bioRxiv; and use of social media and emails to key authors to identify any unpublished datasets. The primary outcome was post-traumatic stress symptoms after treatment (<1 month after the final session). Predominantly, one-stage random-effects models were fitted. This study is registered with PROSPERO, CRD42019151954.

FINDINGS

We identified 38 studies; 25 studies provided individual participant data, comprising 1686 young people (mean age 13·65 years [SD 3·01]), with 802 receiving CBTs-TF and 884 a control condition. The risk-of-bias assessment indicated five studies as low risk and 20 studies with some concerns. Participants who received CBTs-TF had lower mean post-traumatic stress symptoms after treatment than those who received the control conditions, after adjusting for post-traumatic stress symptoms before treatment (b=-13·17, 95% CI -17·84 to -8·50, p<0·001, τ2=103·72). Moderation analysis indicated that this effect of CBTs-TF on post-traumatic stress symptoms post-treatment increased by 0·15 units (b=-0·15, 95% CI -0·29 to -0·01, p=0·041, τ2=0·03) for each unit increase in pre-treatment post-traumatic stress symptoms.

INTERPRETATION

This is the first individual participant data meta-analysis of young people exposed to trauma. Our findings support CBTs-TF as the first-line treatment, irrespective of age, gender, trauma characteristics, or carer involvement in treatment, with particular benefits for those with higher initial distress.

The promise of compassion-based therapy as a novel intervention for adolescent PTSD

In this review, we summarize current evidence for compassion-based approaches for PTSD and the potential for their application to the adolescent PTSD population. Exposure to traumatic events is common in adolescence and PTSD remains a public health crisis. Accessibility, willingness, and engagement are significant barriers to established treatments for PTSD, with attrition rates as high as 50 %. Compassion-based therapies provide potential solutions to treatment obstacles by providing a non-threatening, transdiagnostic option unburdened by aspects of current trauma treatment which may be associated with treatment resistance (e.g., exposure, trauma narrative, induction of fear). Compassion-based approaches are intuitive for trauma treatment, as compassion activates the self-soothing system, thereby disarming the fear system and promoting affect regulation. Compassion-based treatments demonstrate reductions across a substantial range of PTSD symptoms in adults, however, in adolescents extant literature is sparse, with cross-sectional studies suggesting self-compassion is inversely associated with trauma-related psychopathology. Understanding the impact of compassion-based approaches on adolescent PTSD is warranted as the adolescent developmental period may be a particularly opportune time for this approach. Evaluation of the impact of compassion-based treatment on adolescent PTSD in clinical populations via randomized-controlled studies and comparison of its relative efficacy to current evidence-based practices is warranted.

Editorial: Are Group-Based Interventions Effective for Treating Trauma-Related Psychopathology in Children and Young People?

Trauma-exposed young people are about twice as likely as their unexposed peers to develop mental health problems, which, if left untreated, can have long-term negative consequences.1 There is robust evidence for the effectiveness of individual trauma-focused psychological therapies to improve trauma-related psychopathology, particularly posttraumatic stress disorder (PTSD), in young people.2 However, there are minimal services that provide such specialist treatments in low/middle-income countries where most young people live,3 and services may be severely disrupted at times of extreme stressors, such as war, natural disasters, and other humanitarian crises, when need is greatest.4 Moreover, even in high-income stable regions where child mental health services are established and treatments are available, these health care resources are limited, and can only be accessed by a minority of affected trauma-exposed young people.5 There is therefore a need for research to indicate effective interventions that are more accessible and can be delivered on a greater scale to treat more young people with trauma-related psychopathology.6 The recent meta-analysis by Davis et al.7 focused on the more accessible intervention of group-based psychological treatment for child PTSD symptoms, and found evidence of effectiveness compared with control conditions. The study provides an important advancement in this field, and also highlights the need for further research to better understand how group interventions can be most usefully implemented.

Persistence and clinical consequences of post-traumatic and dissociative symptoms in people with depressive symptoms: a one-year follow-up study

BACKGROUND

Recent studies found that post-traumatic and dissociative symptoms are common in people with depressive symptoms. Although a trauma-related subtype of depression has been proposed, little is known about the persistence and clinical consequences of these symptoms.

OBJECTIVE

This one-year follow-up study investigated the persistence and clinical consequences of post-traumatic and dissociative symptoms in people with depressive symptoms.

METHODS

We analyzed longitudinal data from an international sample of people self-reporting depressive emotions (N = 152) (mean Patient Health Questionnaire-9 score = 17.27; SD = 6.31).

RESULTS

More than half (58.4%) of participants with baseline post-traumatic stress disorder (PTSD) still met the criteria for PTSD after one year. Participants with dissociative symptoms at baseline were significantly more likely to report lifetime psychiatric hospitalization (31.2% vs 14.7%), past-year use of psychiatric hospitalization (10.4% vs 0%) and emergency services (16.9% vs 4%) than those without dissociative symptoms. All post-traumatic and dissociative symptom clusters were cross-sectionally (r = .286 to .528, p < .001) and longitudinally (r = .181 to .462, p < .001) correlated with depressive symptoms. A sense of current threat (β = .146, p < .05) and negative self-concept (β = .173, p < .05) at baseline significantly predicted depressive symptoms after one year.

CONCLUSIONS

These findings contribute to the increasing body of knowledge regarding the PTSD/dissociation-depression comorbidity. Given their persistence and clinical consequences, we recommend that post-traumatic and dissociative symptoms be regularly screened for in clinical settings. The existence of a possible trauma-related subtype of depression should receive more attention in both research and clinical practice.

Dissociative episodes characterised by hair-pulling in a late adolescent woman

A woman in late adolescence with a history of sickle cell disease, moyamoya disease, cerebrovascular accident, mild intellectual disability, post-traumatic stress disorder, functional seizures, generalised anxiety disorder and transient psychosis was referred for a psychiatry consultation. She presented with worsening episodes of dissociation characterised by compulsory hair-pulling. Limited research exists regarding patients engaging in activities of automated behaviour during episodes of dissociation. Thus, we aim to describe a case of a patient with episodes of hair-pulling during dissociative events to discuss the aetiology and treatment. We are describing the aetiology and treatment of a patient with episodes of hair-pulling during dissociative events.

Hypothalamus and Post-Traumatic Stress Disorder: A Review

Humans have lived in a dynamic environment fraught with potential dangers for thousands of years. While fear and stress were crucial for the survival of our ancestors, today, they are mostly considered harmful factors, threatening both our physical and mental health. Trauma is a highly stressful, often life-threatening event or a series of events, such as sexual assault, war, natural disasters, burns, and car accidents. Trauma can cause pathological metaplasticity, leading to long-lasting behavioral changes and impairing an individual's ability to cope with future challenges. If an individual is vulnerable, a tremendously traumatic event may result in post-traumatic stress disorder (PTSD). The hypothalamus is critical in initiating hormonal responses to stressful stimuli via the hypothalamic-pituitary-adrenal (HPA) axis. Linked to the prefrontal cortex and limbic structures, especially the amygdala and hippocampus, the hypothalamus acts as a central hub, integrating physiological aspects of the stress response. Consequently, the hypothalamic functions have been attributed to the pathophysiology of PTSD. However, apart from the well-known role of the HPA axis, the hypothalamus may also play different roles in the development of PTSD through other pathways, including the hypothalamic-pituitary-thyroid (HPT) and hypothalamic-pituitary-gonadal (HPG) axes, as well as by secreting growth hormone, prolactin, dopamine, and oxytocin. This review aims to summarize the current evidence regarding the neuroendocrine functions of the hypothalamus, which are correlated with the development of PTSD. A better understanding of the role of the hypothalamus in PTSD could help develop better treatments for this debilitating condition.

A comparison of ICD-11 and DSM-5 criteria of PTSD among Chinese trauma-exposed adolescent samples

This study aimed at comparing the prevalence and comorbidity differences of PTSD according to ICD-11 and DSM-5 definitions across two Chinese adolescent trauma-exposed samples. A total of 1,201 students exposed to earthquake and 559 students from vocational schools exposed to potentially traumatic events were included in this study. The PTSD Checklist for DSM-5 was used to measure PTSD symptoms. The MDD and GAD subscales of the Revised Children's Anxiety and Depression Scale were used to measure major depression disorder (MDD) and generalized anxiety disorder (GAD) symptoms. No significant PTSD prevalence differences between ICD-11 and DSM-5 were found across the two samples. The differences regarding comorbidities between ICD-11 and DSM-5 definitions were not significant among these two samples. The results revealed that the ICD-11 and DSM-5 provided similar prevalence of PTSD and comorbidity rates with MDD and GAD in Chinese trauma-exposed adolescent samples. This study contributes to the current understanding of the similarities and differences using different PTSD criteria and informs the organization and application of these two globally applied PTSD criteria.

Overlap Between Exposure to Suicidal Behavior and Indirect Interpersonal Violence: Evidence for a More Integrated Approach to Violence Research

This study examines the overlap between indirect exposure to forms of interpersonal violence and suicidal behavior, and the impact of the co-occurrence of these exposures on indicators of depressed mood and substance use among adolescents. Participants were a national sample of 3,917 youth aged 14-15 years, recruited online between June 2018 and March 2020, including an oversample of sexual and gender minority youth. Eight in ten (81.3%) youth reported exposure to indirect interpersonal violence and/or suicidal behavior in their lifetimes: 39.5% reported only interpersonal violence exposure, 5.9% only suicidal behavior exposure, and 35.9% reported both. Youth who reported exposure to interpersonal violence were almost three times more likely (adjusted odds ratio [OR] = 2.78, p < .001) to also report suicidal behavior exposure. Compared with youth having no indirect violence exposure, those with only interpersonal violence exposure were 2.25 times more likely (p < .001), those with only exposure to suicidal behavior 2.93 times more likely (p < .001), and those with both were 5.63 times more likely to report recent depressed mood. The unadjusted odds of any substance use was significantly elevated for each type of indirect violence exposure, with the highest odds seen among youth with dual interpersonal violence and suicide exposure (OR = 4.87, p < .001). For both outcomes, significant findings remained but were attenuated after adjusting for demographic characteristics, non-victimization adversity exposure, and cumulative direct victimization. Findings suggest that the combination of exposure to interpersonal violence and suicidal behavior appears to be particularly impactful. Results highlight that assessment of trauma exposure among adolescents needs to be more comprehensive and include not only direct and indirect interpersonal violence, but also knowledge of other people's suicidal thoughts and behaviors.

Transforming Empathy-Based Stress to Compassion: Skillful Means to Preventing Teacher Burnout

Objectives

Teachers play a critical role in preparing our children and adolescents for a successful future. However, despite the large number of students impacted by trauma and adversity, teachers are often not well prepared to provide trauma-sensitive support. Furthermore, while working to support students exposed to trauma and adversity, teachers may experience empathy-based stress exacerbating already high levels of stress among them. This narrative review explores the issue of empathy-based stress within the context of the prosocial classroom model which proposes that teachers' social and emotional competence and well-being are key to their ability to create and maintain supportive learning environments critical to student academic and behavioral outcomes.

Methods

Recent findings in neuroscience and education research are applied to support teachers' development of these competencies.

Results

We propose that shifting from empathy-based stress to compassionate responding may be one such competency to help teachers' respond effectively to their students' needs while protecting their own wellbeing.

Conclusion

We review research that supports this proposition and explore implications for teacher professional learning, educational policy, and further research.

The Prevalence, Patterns and Correlates of Childhood Trauma Exposure in a Nationally Representative Sample of Young People in Northern Ireland

PURPOSE

Childhood trauma (CT) exposure is common, with many young people affected by multiple co-occurring traumas.

METHODS

Participants were a representative sample of 11-19-year-olds (n = 1293), who participated in the largest ever representative survey of youth mental health in Northern Ireland (NI) - the NI Youth Wellbeing Prevalence Survey 2020. This study used latent class analysis (LCA) to identify typologies that were most representative of trauma experience and co-occurrence among young people living in NI. Demographic, parental and deprivation variables were then used within a multinomial logistic regression analysis to describe trauma class membership.

RESULTS

Over 35% (n = 478) of participants reported exposure to at least one CT, with over 50% (n = 259) of trauma-exposed young people reporting multiple trauma exposure. LCA results provided support for a three-class model; 'low-exposure', 'moderate-exposure: community-victimization' and 'high-exposure: sexual-trauma'. While none of the child, parental or familial covariates differentiated members of the 'moderate-exposure: community-victimization' from 'low-exposure', those in 'high-exposure: sexual-trauma' were over four and a half times more likely to belong to a family in receipt of income benefits and over ten times more likely to have experienced some form of out-of-home care.

CONCLUSIONS

This study highlights the presence of three distinct trauma classes in the NI adolescent population. In particular, this study identifies a small minority of young people who have experienced multiple CT's, including sexually based traumas, with these traumas most likely to have occurred in the context of out-of-home care and familial poverty.

Eye Movement Desensitization and Reprocessing in Young Children (Ages 4-8) with Posttraumatic Stress Disorder: A Multiple-Baseline Evaluation

To reduce the acute and long-term effects of trauma, early and effective treatment is necessary. Eye movement desensitization and reprocessing (EMDR) therapy is a brief treatment for posttraumatic stress disorder (PTSD), with a substantial evidence base for children and adolescents aged 8 to 18 years. In the present study we aimed to provide preliminary evidence of EMDR as a trauma treatment for young children. We studied 9 children, aged 4 to 8 years old with a DSM-5 diagnosis of PTSD. A non-concurrent multiple baseline experimental design was used combined with standardized measures. Participants received six 1-h sessions of EMDR. Results post-treatment showed that EMDR was effective in reaching diagnostic remission of PTSD (85.7%), and decreasing severity of PTSD symptoms and emotional and behavioral problems. All gains were maintained at follow-up 3 months after treatment. EMDR appears an effective treatment for PTSD in young children aged 4 to 8 years. Further research is warranted.

Brief internet-delivered cognitive-behavioural intervention for children and adolescents with symptoms of anxiety and depression during the COVID-19 pandemic: a randomised controlled trial protocol

BACKGROUND

The COVID-19 pandemic has had major impacts in many different spheres, including mental health. Children and adolescents are especially vulnerable because their central nervous system is still in development and they have fewer coping resources than do adults. Increases in the prevalence of depressive and anxiety symptomatology have been reported worldwide. However, access to mental health care is limited, especially for the paediatric population and in low- and middle-income countries. Therefore, we developed a brief internet-delivered cognitive-behavioural intervention for children and adolescents with symptoms of anxiety and depression. The aim of this proposed study is to test the efficacy of the intervention.

METHODS

We will conduct a two-arm, parallel randomised controlled trial involving children and adolescents (8-11 and 12-17 years of age, respectively) with symptoms of anxiety, depression or both, according to the 25-item Revised Child Anxiety and Depression Scale (t-score > 70). A total of 280 participants will be randomised to the intervention group or the active control group, in a 1:1 ratio. Those in the intervention group will receive five weekly sessions of cognitive-behavioural therapy via teleconference. The sessions will focus on stress responses, family communication, diaphragmatic breathing, emotions, anger management, behavioural activation and cognitive restructuring. Participants in both groups will have access to 15 videos covering the same topics. Participant-guardian pairs will be expected to attend the sessions (intervention group), watch the videos (control group) or both (intervention group only). A blinded assessor will collect data on symptoms of anxiety, depression and irritability, at baseline, at the end of the intervention and 30 days thereafter. Adolescents with access to a smartphone will also be invited to participate in an ecological momentary assessment of emotional problems in the week before and the week after the intervention, as well as in passive data collection from existing smartphone sensors throughout the study.

DISCUSSION

Internet-delivered interventions play a major role in increasing access to mental health care. A brief, manualised, internet-delivered intervention might help children and adolescents with anxiety or depressive symptomatology, even outside the context of the COVID-19 pandemic.

Using Time-out for Child Conduct Problems in the Context of Trauma and Adversity: A Nonrandomized Controlled Trial

IMPORTANCE

Exposure to adverse childhood experiences substantially increases the risk of chronic health problems. Originally designed to treat child conduct problems, parent management training programs have been shown to be effective in preventing children from being exposed to further adversity and supporting children's recovery from adversity; however, there are increasing concerns that a core component of these programs, the discipline strategy time-out, may be harmful for children with a history of exposure to adversity.

OBJECTIVE

To investigate the comparative benefits and potential harms to children exposed to adversity that are associated with parenting programs that include time-out.

DESIGN, SETTING, AND PARTICIPANTS

This nonrandomized waiting list-controlled clinical study was conducted at a specialist clinic for the treatment of conduct problems in Sydney, Australia. The self-referred sample included children with conduct problems and their caregivers. Eligibility was confirmed through clinician-administered interviews. Data were collected between February 14, 2018, and February 1, 2021.

INTERVENTIONS

Caregivers participated in a 10-session, social learning-based parent management training program. Caregivers were provided with parenting strategies aimed at encouraging desired behaviors through effective reinforcement and managing misbehavior through consistent limit setting, including the use of time-outs.

MAIN OUTCOMES AND MEASURES

The primary outcome was the parent-reported Strengths and Difficulties Questionnaire score, and secondary outcomes included subscale scores from the clinician-administered Diagnostic Interview Schedule for Children, Adolescents, and Parents. Multi-informant measures of child adversity were collected using the parent-reported Adverse Life Experiences Scale and the clinician-rated Maltreatment Index.

RESULTS

A total of 205 children were included in analysis (156 in the full intervention and 49 in the control condition; 158 boys [77.1%]; mean [SD] age, 5.6 [1.8] years [range, 2-9 years]). Compared with children with low adversity exposure, children with high adversity exposure showed greater reductions in the Strengths and Difficulties Questionnaire score from baseline (mean difference, 3.46 [95% CI, 1.51-5.41]; P < .001) to after treatment (mean difference, 1.49 [95% CI, -0.46 to 3.44]; P = .13) and in the internalizing symptom subscale score (baseline mean difference, 1.00 [95% CI, -2,00 to 0.00]; P = .50; posttreatment mean difference, 0.06 [95% CI, -0.82 to 0.94]; P = .90). No significant differences in the externalizing symptom subscale score were found.

CONCLUSIONS AND RELEVANCE

In this nonrandomized clinical study, children with high exposure to adversity experienced equivalent, if not greater, benefits associated with parenting programs that include time-out compared with children with low exposure to adversity. Results suggest that time-out was an effective component of parenting programs for children exposed to adversity.

Validation of the International Trauma Questionnaire-Child and Adolescent Version (ITQ-CA) in a Chinese mental health service seeking adolescent sample

BACKGROUND

The International Trauma Questionnaire-Child and Adolescent version (ITQ-CA) is a self-report measure that assesses posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on the diagnostic formulation of the 11th version of the International Classification of Diseases (ICD-11). This study aimed to provide a Chinese translation and psychometric evaluation of the ITQ-CA using a sample of mental-health service seeking adolescents in Mainland China.

METHODS

The ITQ-CA was translated and back-translated from English to simplified Chinese and finalized with consensus from an expert panel. Adolescents ages 12-17 were recruited via convenience sampling from an outpatient psychiatric clinic in Mainland China. Participants completed the ITQ-CA; measures of four criterion variables (depression, anxiety, stress, adverse childhood experiences); and the PTSD Checklist for DSM-5 (PCL-5). Construct validity, concurrent validity, and comparison of PTSD caseness between ICD-11 and DSM-5 measures were assessed.

RESULTS

The final sample consisted of 111 Chinese adolescents (78% female; mean age of 15.23), all diagnosed with a major depressive disorder. Confirmatory factor analysis indicated the two-factor second-order model provided optimal fit. All criterion variables were positively and significant correlated with the six ITQ-CA symptom cluster summed scores. In the present sample, 69 participants (62.16%) met symptom criteria for ICD-PTSD or CPTSD using the ITQ-CA, and 73 participants (65.77%) met caseness for DSM-5 PTSD using the PCL-5. Rates of PTSD symptom cluster endorsement and caseness deriving from both diagnostic systems were comparable.

CONCLUSIONS

The Chinese ITQ-CA has acceptable psychometric properties and confers additional benefits in identifying complex presentations of trauma-related responses in younger people seeking mental health services.

Evidence-based practice in cognitive-behavioural therapy

Cognitive-behavioural therapy (CBT) is a practical, goal-focused approach that helps children understand the relationship between their thoughts, feelings and behaviours. The aim is to identify the dysfunctional and distorted cognitions associated with their psychological problems and to create more functional and balanced cognitive patterns that create less emotional distress and more helpful behaviours. CBT has strong evidence as an effective intervention for children and adolescents with emotional problems. The benefits for children with physical health and chronic conditions appear promising, although further research is required to substantiate these gains.

Online training for evidence-based child trauma treatment: evaluation of the German language TF-CBT-Web

BACKGROUND

Evidence-based trauma-focused interventions for treating PTSD in children and youth are barely used in practice. Web-based training has proven to be an effective way of transferring knowledge to healthcare professionals.

OBJECTIVE

TF-CBT Web is a web-based training programme designed to foster the dissemination of Trauma Focused Cognitive Behavioural Therapy (TF-CBT) for children and youth, and is run by the Medical University of South Carolina. This paper describes the characteristics of healthcare professionals who registered for the adapted German language version of TF-CBT Web. It evaluates the effectiveness and user friendliness of the programme.

METHOD

: Similar to the TF-CBT treatment manual, the German language TF-CBT Web contains 12 modules. Between 2018 and 2020, 4,020 users registered for the programme. During the registration process users provided demographic information. The knowledge of users regarding the TF-CBT components was assessed via pre-tests and post-tests in each module.

RESULTS

The programme was accessed by a sample of mostly German users with varying professional health care backgrounds and a wide-ranging spread of work experience. The results indicated a significant knowledge gain and high rates of user satisfaction with the programme.

CONCLUSIONS

In summary, the results of this study suggested that web-based training is an effective and well-accepted method for knowledge gain in trauma-focused interventions. Future research should evaluate the actual application of the taught methods in clinical practice.

HIGHLIGHTS

Children and adolescents with PTSD require trauma-focused treatment. However, evidence-based interventions for this patient population are barely used. Therefore, it is necessary to expand professional training for the treatment of traumatised children and adolescents.Our evaluation showed the effectiveness and feasibility of a web-based training programme for mental health practitioners in an evidence-based treatment for children and youth with PTSD (TF-CBT). Results show a significant knowledge gain of users who participate in the web-based training programme.The user satisfaction survey also revealed that users found the modus and content of the web-based training applicable and relevant for their clinical practice.

The early course and treatment of posttraumatic stress disorder in very young children: diagnostic prevalence and predictors in hospital-attending children and a randomized controlled proof-of-concept trial of trauma-focused cognitive therapy, for 3- to 8-year-olds

BACKGROUND

The introduction of developmentally adapted criteria for posttraumatic stress disorder (PTSD) has improved the identification of ≤6-year-old children with clinical needs. Across two studies, we assess predictors of the development of PTSD in young children (PTSD-YC), including the adult-led acute stress disorder (ASD) diagnosis, and provide proof of principle for cognitive-focused therapy for this age range, with the aim of increasing treatment options for children diagnosed with PTSD-YC.

METHOD

Study 1 (N = 105) assessed ASD and PTSD-YC diagnosis in 3- to 8-year-old children within one month and at around three months following attendance at an emergency room. Study 2 (N = 37) was a preregistered (www.isrctn.com/ISRCTN35018680) randomized controlled early-phase trial comparing CBT-3M, a cognitive-focused intervention, to treatment-as-usual (TAU) delivered within the UK NHS to 3- to 8-year-olds diagnosed with PTSD-YC.

RESULTS

In Study 1, the ASD diagnosis failed to identify any young children. In contrast, prevalence of acute PTSD-YC (minus the duration requirement) was 8.6% in the first month post-trauma and 10.1% at 3 months. Length of hospital stay, but no other demographic or trauma-related characteristics, predicted development of later PTSD-YC. Early (within one month) diagnosis of acute PTSD-YC had a positive predictive value of 50% for later PTSD-YC. In Study 2, most children lost their PTSD-YC diagnosis following completion of CBT-3M (84.6%) relative to TAU (6.7%) and CBT-3M was acceptable to recipient families. Effect sizes were also in favor of CBT-3M for secondary outcome measures.

CONCLUSIONS

The ASD diagnosis is not fit for purpose in this age-group. There was a strong and encouraging signal of putative efficacy for young children treated using a cognitive-focused treatment for PTSD, and a larger trial of CBT-3M is now warranted.

Effectiveness of creative arts-based interventions for treating children and adolescents exposed to traumatic events: a systematic review of the quantitative evidence and meta-analysis

BACKGROUND

The effect of interventions based on the creative arts for children and adolescents exposed to traumatic events was estimated for measures of post-traumatic stress disorder (PTSD) and other psychological symptoms.

METHOD

Using a pre-registered protocol, relevant journal articles were identified through searches of: PsycInfo; Psychology and Behavioural Sciences Collection; CINAHL and PsycArticles. Data were pooled using a random effects model, and effect estimates were reported as Hedges' g.

RESULTS

Pooled effect estimates indicated that arts-based interventions significantly reduced PTSD symptom scores compared to pre-intervention (15 studies, g = -.67, p < .001) and a control group (7 studies, g = -.50, p < .001). Significant reductions were also found for measures of negative mood, but results were mixed for externalizing problems and anxiety.

CONCLUSIONS

Despite variations in study quality, intervention approaches and types of trauma experience, the results tentatively suggest that creative arts-based interventions may be effective in reducing symptoms of trauma and negative mood.

[Association between psychological violence and posttraumatic stress disorder in a cohort of Brazilian adolescents]

The study analyzed the impact of psychological violence on the development of posttraumatic stress disorder (PTSD). This was a cross-sectional study nested in a cohort in which the second follow-up was conducted in 2016. A questionnaire was applied to 2,486 adolescents and approached individual, family, and social aspects and experience with psychological violence. Propensity score was used to create inverse probability weighting (IPW). Thus, a probability was assigned to each adolescent, where 1/IPW represent those in the exposed group and 1/(1-IPW) those in the unexposed group. This procedure made the two groups more homogeneous and mutually comparable. The association between the occurrence of psychological violence and PTSD was estimated by odds ratios (OR) and 95% confidence intervals (95%CI) via crude binary logistic regression and adjusted logistic regression (weighted by IPW). According to the results, 30.3% reported having suffered severe violence. Prevalence of PTSD was 4.8% among exposed and 1.5% in unexposed to psychological violence. An association was observed between severe violence and PTSD in the two analyses, but the magnitude in the model structured by the propensity score (OR = 1.97; 95%CI: 1.08-3.56) indicated an adjustment to the measure from the crude analysis (OR = 3.40; 95%CI: 2.03-5.69). The current study contributes to the scarce literature on exposure to psychological violence and its association with the development of PTSD, confirming the negative impact of this form of abuse on the individual´s mental health.

Four perspectives on traumatized youths' therapeutic alliance: Correspondence and outcome predictions

OBJECTIVE

Does the rater-perspective of youths' therapeutic alliance matter? To answer this, we evaluated the relationships between four perspectives of youths' alliance, then, we examined whether each perspective and potential discordance between the perspectives predicted outcomes.

METHOD

Participants were 65 youth (M age = 15.11, SD = 2.14; 76.9% girls) undergoing trauma-focused cognitive behavioral therapy (TF-CBT) and their therapists (n = 24). Youths' alliance was rated by youth, therapists and parents using the Therapeutic Alliance Scale for Children-revised and by observers using the Therapy Process Observational Coding System-Alliance scale. Posttraumatic stress symptoms (PTSS) were assessed with the Child PTSD Symptom Scale (CPSS) and the Clinician Administered PTSD Scale for Children and Adolescents (CAPS-CA).

RESULTS

The alliance ratings by youth-parent, parent-therapist, and therapist-observer significantly correlated. Only a higher youth-rated alliance significantly predicted fewer PTSS. Furthermore, a higher therapist-rated than youth-rated alliance significantly predicted higher scores on CPSS and CAPS-CA, and a higher parent-rated than youth-rated alliance predicted significantly higher CPSS score.

CONCLUSION

Therapists should explicitly check in with youth clients about the alliance; because only youths' evaluation of their alliance predicted the outcome and an overestimation of their alliance by therapists and parents predicted more PTSS.Trial registration: ClinicalTrials.gov identifier: NCT00635752..

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

BACKGROUND

Available evidence on the comparative efficacy and acceptability of psychotherapies for post-traumatic stress disorder (PTSD) in children and adolescents remains uncertain.

OBJECTIVE

We aimed to compare and rank the different types and formats of psychotherapies for PTSD in children and adolescents.

METHODS

We searched eight databases and other international registers up to 31 December 2020. The pairwise meta-analyses and frequentist network meta-analyses estimated pooled standardised mean differences (SMDs) and ORs with random-effects model. Efficacy at post-treatment and follow-up, acceptability, depressive and anxiety symptoms were measured.

FINDINGS

We included 56 randomised controlled trials with 5327 patients comparing 14 different types of psychotherapies and 3 control conditions. For efficacy, cognitive processing therapy (CPT), behavioural therapy (BT), individual trauma-focused cognitive-behavioural therapy (TF-CBT), eye movement desensitisation and reprocessing, and group TF-CBT were significantly superior to all control conditions at post-treatment and follow-up (SMDs between -2.42 and -0.25). Moreover, CPT, BT and individual TF-CBT were more effective than supportive therapy (SMDs between -1.92 and -0.49). Results for depressive and anxiety symptoms were similar to the findings for the primary outcome. Most of the results were rated as 'moderate' to 'very low' in terms of confidence of evidence.

CONCLUSIONS

CPT, BT and individual TF-CBT appear to be the best choices of psychotherapy for PTSD in young patients. Other types and different ways of delivering psychological treatment can be alternative options. Clinicians should consider the importance of each outcome and the patients' preferences in real clinical practice.

Evaluation of an Early Intervention Model for Child and Adolescent Victims of Interpersonal Violence

Only the minority of youth exposed to traumatic events receive mental health care, as trauma-informed clinical services are lacking or are poorly accessible. In order to bridge this gap, the Outpatient Trauma Clinic (OTC) was founded, an easily accessible early, short-time intervention, with onward referral to follow-up treatment. This report presents the OTC's interventional approach and first outcome data. Using a retrospective naturalistic design, we analyzed trauma- and intervention-related data of the sample (n = 377, 55.4% female, mean age 10.95, SD = 4.69). Following drop-out analyses, predictors for treatment outcome were identified by logistic regression. The majority (81.9%) was suffering from posttraumatic stress disorder (PTSD) or adjustment disorders. Around one forth dropped out of treatment; these cases showed higher avoidance symptoms at presentation. In 91%, psychological symptoms improved. Experience of multiple traumatic events was the strongest predictor for poor treatment outcome (B = -0.823, SE = 0.313, OR = 0.439, 95% CI 0.238-0.811). Around two thirds were connected to follow-up treatment. The OTC realized a high retention rate, initial improvement of symptoms and referral to subsequent longer-term psychotherapeutic treatment in the majority. Further dissemination of comparable early intervention models is needed, in order to improve mental health care for this vulnerable group.

Population Prevalence of the Posttraumatic Stress Disorder Subtype for Young Children in Nationwide Surveys of the British General Population and of Children in Care

OBJECTIVE

Posttraumatic stress disorder (PTSD) is a debilitating condition that when left untreated can have severe lifelong consequences for psychological, social, and occupational functioning. Initial conceptualizations of PTSD were centered on adult presentations. However, the instantiation of developmentally appropriate PTSD in young children (PTSD-YC) criteria, tailored to preschool (6 years old and younger) children, represents an important step toward identifying more young children experiencing distress. This study explored population-level prevalence of PTSD-YC indexed via an alternative algorithm for DSM-IV PTSD (AA-PTSD).

METHOD

Representative population data were used to test whether application of AA-PTSD criteria, relative to the DSM-IV PTSD algorithm, increased identification of 5- to 6-year-old children with clinical needs in both the general population (n = 3,202) and among looked after children (ie, in Britain, foster children are called looked after children [more commonly referred to as children in care].) (n = 137), in whom the risk of mental health issues is greater.

RESULTS

Notably, no 5- to 6-year-old children in the general population sample were diagnosed with PTSD using adult-based DSM-IV criteria. In contrast, AA-PTSD prevalence was 0.4% overall, rising to 5.4% in trauma-exposed children. In looked after children, overall PTSD prevalence rose from 1.2% when applying adult-based DSM-IV criteria to 14% when using AA-PTSD criteria. Of trauma-exposed looked after children, 2.7% met criteria for DSM-IV PTSD compared with 57.0% when applying AA-PTSD criteria. In both samples, use of the alternative algorithm to index PTSD-YC criteria markedly increased identification of children experiencing functional impairment owing to symptoms.

CONCLUSION

Results demonstrate the utility of the PTSD-YC diagnosis beyond at-risk and treatment-seeking samples. Use of PTSD-YC criteria substantially improves identification of 5- to 6-year-old children burdened by PTSD at the population level.

Five-Year Psychosocial Impact of Living in Postdisaster Prefabricated Temporary Housing

OBJECTIVE

This study aims to evaluate the long-term impact of living in postdisaster prefabricated temporary housing on social interaction activities and mental health status.

METHODS

A total of 917 adult residents in a coastal town, whose residences were destroyed by the tsunami caused by the Great East Japan Earthquake (GEJE), were enrolled for the assessment held 5 y after the disaster. They answered questions about their experience and consequence of living in prefabricated temporary housing after the disaster. Their present scores on 5 types of self-reported measures regarding the psychosocial or psychiatric status and their present and recalled social interaction activities were cross-sectionally collected.

RESULTS

A total of 587 (64.0%) participants had a history of living in prefabricated temporary housing, while the other 330 (36.0%) had not. The prevalence of social interaction activities significantly decreased after the GEJE. However, the experience of living in prefabricated temporary housing did not adversely affect the subsequent social interaction activities or mental conditions of the participants 5 y after the disaster.

CONCLUSIONS

Living in postdisaster prefabricated temporary housing may not negatively impact subsequent psychosocial conditions or social interaction activities 5 y later.

Effectiveness of an intensive treatment programme combining prolonged exposure and EMDR therapy for adolescents suffering from severe post-traumatic stress disorder

Background: Following promising effects of an intensive trauma treatment for adults, the question arises whether adolescents who suffer from severe post-traumatic stress disorder (PTSD) can also profit from a similar treatment programme. Objective: To assess the effectiveness of an intensive trauma-focused treatment programme combining two evidence-based trauma-focused therapies and physical activities for adolescents suffering from severe PTSD. Method: Treatment consisted of daily sessions of prolonged exposure (PE) therapy and eye movement desensitization and reprocessing (EMDR) therapy supplemented with physical activity (13 days on average). All patients (N = 27; 96.3% women, mean age = 16.1 years; SD = 1.3) had been exposed to one or more (interpersonal) traumatic events. Twenty-two of them (81.5%) also fulfilled the diagnostic criteria of a comorbid psychiatric disorder (mean number of comorbid disorders = 2.22). The majority of patients were referred because previous treatment was difficult or complications were expected to occur. Severity of PTSD symptoms and presence of a PTSD diagnostic status were assessed using the Dutch version of the CAPS-CA IV at baseline, post-treatment and at 3-month follow-up. Results: CAPS-CA IV scores decreased significantly from pre- to post-treatment (Cohen's d = 1.39). Of all patients 81.5% (n = 22) showed a clinically meaningful response, of whom 63% (n = 17) no longer fulfilled the diagnostic criteria of PTSD at post-treatment as established with the CAPS-CA IV. The results were maintained at 3-month follow-up. During treatment, neither adverse events nor dropout occurred. Conclusions: The results suggest that an intensive trauma-focused treatment programme combining prolonged exposure, EMDR therapy, and physical activity can be an effective and safe treatment for adolescents suffering from severe PTSD and multiple comorbid psychiatric disorders.

Unaccompanied minors’ experiences of narrative exposure therapy

Despite the understanding that unaccompanied minors’ (UAM) experience high rates of post-traumatic stress, the provision of evidence-based trauma-focused therapies is low for this population. Narrative exposure therapy (NET) is an effective short-term intervention for treating post-traumatic stress disorder (PTSD) after multiple traumatic experiences, such as those experienced by UAM. Within the existing literature, there is a lack of research investigating unaccompanied minors’ experiences of NET or any trauma-focused therapy. Participants were four UAM experiencing PTSD who formed part of a pilot delivery of NET within a dedicated child and adolescent mental health service for refugee children. Semi-structured interviews were conducted and transcripts were analysed using interpretative phenomenological analysis (IPA). This project identified five themes that encapsulated unaccompanied minors’ experiences of receiving NET, including the process of preparing for this therapy, what it was like to receive it, and the differences they identified at the end of treatment. The significance of this taking place within a safe therapeutic relationship was explored within the context of the attachment losses experienced by UAM, and the impact this has on emotion regulation was considered. The potential of a reduction in PTSD symptoms facilitating a positive spiral in adolescence was reflected on within this paper.

Foster children's complex psychopathology in the context of cumulative childhood trauma: The interplay of ICD-11 complex PTSD, dissociation, depression, and emotion regulation

BACKGROUND

Foster children experience maltreatment at exceptionally high rates with increased risk to develop ICD-11 complex posttraumatic stress disorder (CPTSD). While rates of comorbidity between CPTSD and various disorders are high, the interplay between constituent aspects of psychopathology is not clearly understood. No study used network analysis to model the interplay between these aspects as potentially maintaining a stable condition of psychopathology, and research on the etiology and maintenance of CPTSD in children is especially scarce.

METHODS

Altogether, 208 Austrian foster children completed a set of standardized measures, resulting in a final sample of N = 122 foster children meeting the inclusion criteria. Experiences of childhood trauma, ICD-11 CPTSD, depression, dissociation, adaptive, and maladaptive emotion regulation were assessed. Following an exploratory approach, analyses were conducted using latent single indicator factor scores in two network models.

RESULTS

Domains of CPTSD, PTSD and disturbances in self-organization (DSO), evidenced as most central factors in children's complex psychopathology. Including cumulative childhood trauma did not influence the connectedness of factors in any relevant way. Shortest direct paths from cumulative childhood trauma to CPTSD included dissociation (PTSD) and adaptive emotion regulation (DSO) as mediating factors.

LIMITATIONS

Results are based on a small sample of highly-traumatized foster children, potentially limiting current findings' generalizability.

CONCLUSIONS

CPTSD identified as central in children's complex psychopathology, while the role of childhood trauma seems stronger for the onset than the maintenance of such psychopathology. The current network revealed central disorders and distinct mediating factors as important targets for treatment strategies and future research.

Prevalence and predictive value of ICD-11 post-traumatic stress disorder and Complex PTSD diagnoses in children and adolescents exposed to a single-event trauma

BACKGROUND

The 11th edition of the International Classification of Diseases (ICD-11) made a number of significant changes to the diagnostic criteria for post-traumatic stress disorder (PTSD). We sought to determine the prevalence and 3-month predictive values of the new ICD-11 PTSD criteria relative to ICD-10 PTSD, in children and adolescents following a single traumatic event. ICD-11 also introduced a diagnosis of Complex PTSD (CPTSD), proposed to typically result from prolonged, chronic exposure to traumatic experiences, although the CPTSD diagnostic criteria do not require a repeated experience of trauma. We therefore explored whether children and adolescents demonstrate ICD-11 CPTSD features following exposure to a single-incident trauma.

METHOD

Data were analysed from a prospective cohort study of youth aged 8-17 years who had attended an emergency department following a single trauma. Assessments of PTSD, CPTSD, depressive and anxiety symptoms were performed at two to four weeks (n = 226) and nine weeks (n = 208) post-trauma, allowing us to calculate and compare the prevalence and predictive value of ICD-10 and ICD-11 PTSD criteria, along with CPTSD. Predictive abilities of different diagnostic thresholds were undertaken using positive/negative predictive values, sensitivity/specificity statistics and logistic regressions.

RESULTS

At Week 9, 15 participants (7%) were identified as experiencing ICD-11 PTSD, compared to 23 (11%) experiencing ICD-10 PTSD. There was no significant difference in comorbidity rates between ICD-10 and ICD-11 PTSD diagnoses. Ninety per cent of participants with ICD-11 PTSD also met criteria for at least one CPTSD feature. Five participants met full CPTSD criteria.

CONCLUSIONS

Reduced prevalence of PTSD associated with the use of ICD-11 criteria is likely to reduce identification of PTSD relative to using ICD-10 criteria but not relative to DSM-4 and DSM-5 criteria. Diagnosis of CPTSD is likely to be infrequent following single-incident trauma.

Posttraumatic Symptoms in 3-7 Year Old Trauma-Exposed Children: Links to Impairment, Other Mental Health Symptoms, Caregiver PTSD, and Caregiver Stress

Few studies have examined how PTSD symptoms in young children are associated with other mental health symptoms and mood and functioning in caregivers. This is an important gap in the literature as such knowledge may be important for assessment and treatment. This study used network analysis to identify how the major symptom domains of PTSD in young trauma-exposed children were related to impairment, internalizing and externalizing symptoms, caregiver PTSD, and caregiver stress. Caregivers of 75 trauma-exposed 3-7 year old children reported on their child's symptoms and impairment and their own PTSD symptoms and caregiver stress. A strong association between the child PTSD domains of intrusions and avoidance emerged, which is in line with theoretical notions of how PTSD onsets and is maintained in adolescents and adults. Externalizing child symptoms were strongly linked to PTSD-related impairment and caregiver stress, highlighting the need to carefully assess and address such symptoms when working with young trauma-exposed children. Internalizing symptoms were uniquely associated with all three of the major childhood PTSD symptom domains with further implications for assessment and treatment.

Can children predict psychological recovery after injury?

While children's voice is core to paediatric care, their own assessment of future psychological needs is underexplored. We conducted a prospective observational study among children hospitalised for injury in Melbourne, Australia. Their expectations of psychological recovery at baseline (in hospital) were significant and substantial predictors of their quality of life and post-traumatic stress 6 weeks later, suggesting potential diagnostic value.

The Role of Gender in the Associations Among Posttraumatic Stress Symptoms, Anger, and Aggression in Russian Adolescents

Symptoms of posttraumatic stress disorder (PTSD) have been linked to anger and aggressive behavior in adult and veteran populations. However, research on the associations among anger, aggression, and PTSD in adolescents is lacking, particularly regarding differences between the sexes. To address this research gap, we used self-report data from Russian adolescents (N = 2,810; age range: 13-17 years) to perform a full path analysis examining the associations between PTSD symptoms and the emotional (anger traits) and cognitive (rumination) components of anger as well as physical/verbal and social aggression, after adjusting for depressive symptoms. We also examined the interaction effects between PTSD symptoms and sex on anger and aggression. The results indicated that girls scored higher on measures of anger and PTSD symptoms, ds = 0.20-0.32, whereas boys scored higher on measures of physical and verbal aggression, d = 0.54. Clinical levels of PTSD symptoms were associated with anger rumination, β = .16, and trait anger, β = .06, and an interaction effect for PTSD symptoms and sex was found for aggression, whereby boys with clinical levels of PTSD symptoms reported more physical/verbal and social aggression, βs = .05 and .20, respectively. Our findings suggest that PTSD symptoms may have an important impact on anger, anger rumination, and aggression during adolescence. In particular, boys seem to have an increased risk for aggressive behavior in the presence of PTSD symptoms. The present results highlight the importance of taking anger and aggression into account when evaluating PTSD.

Long-Term Posttraumatic Stress Following Accidental Injury in Children and Adolescents: Results of a 2-4-Year Follow-Up Study

In this study, we determined the long-term prevalence of posttraumatic stress disorder (PTSD) in children and adolescents after accidental injury and gained insight into factors that may be associated with the occurrence of PTSD. In a prospective longitudinal study, we assessed diagnosed PTSD and clinically significant self-reported posttraumatic stress symptoms (PTSS) in 90 children (11–22 years of age, 60% boys), 2–4 years after their accident (mean number of months 32.9, SD 6.6). The outcome was compared to the first assessment 3 months after the accident in 147 children, 8–18 years of age. The prevalence of PTSD was 11.6% at first assessment and 11.4% at follow-up. Children with PTSD or PTSS reported significantly more permanent physical impairment than children without. Children who completed psychotherapy had no symptoms or low levels of symptoms at follow-up. Given the long-term prevalence of PTSD in children following accidents, we recommend systematic monitoring of injured children. The role of possible associated factors in long-term PTSS needs further study.

Identifying predictors of probable posttraumatic stress disorder in children and adolescents with earthquake exposure: A longitudinal study using a machine learning approach

BACKGROUND

Evidence has identified risk factors associated with individuals with trauma exposure who develop posttraumatic stress disorder (PTSD). How to combine risk factors to predict probable PTSD in young survivors using machine learning is limited. The study aimed to integrated multiple measures at 2 weeks after the earthquake using machine learning for the prediction of probable PTSD at 3 months after earthquake.

METHODS

A total of 2099 young survivors with earthquake exposure were included. We integrated multiple domains of variables to 'train' a machine learning algorithm (XGBoost). Thirty-one combination types were implemented and evaluated. The resulting XGBoost was utilized in identifying individual participants as either probable PTSD or no PTSD.

RESULTS

Any combination type predicted young survivor probable PTSD, with prediction accuracies ranging between 66%-80% (p < 0.05). In particular, the combination of earthquake experience, everyday functioning, somatic symptoms and sleeping correctly predicted 683 out of 802 cases of probable PTSD, translating to a classical accuracy of 74.476% (85.156% sensitivity and 60.366% specificity) and an area under the curve of 0.80. The most relevant variables (e.g. age, sex, property loss and a sedentary lifestyle) revealed in the present study.

LIMITATIONS

Participants from a specific district might limit the generalizability of our results. Self-report questionnaires and non-standardized measures were used to assess symptoms.

CONCLUSION

Detection of probable PTSD according to self-reported measurement data is feasible, may improve operational efficiencies via enabling targeted intervention, before manifestation of symptoms.

Implementing Narrative Exposure Therapy for unaccompanied asylum-seeking minors with post-traumatic stress disorder: A pilot feasibility report

There are high rates of post-traumatic stress disorder (PTSD) in unaccompanied asylum-seeking minors (UAM) and there is a requirement for feasible, acceptable and evidence-based treatments. Narrative Exposure Therapy (NET) is a short-term treatment for PTSD following multiple traumatic events. This article aims to examine the applicability of NET for UAM in routine clinical practice and to provide preliminary feasibility, acceptability and effectiveness data. The participants were four UAM receiving NET within a dedicated child and adolescent mental health service for refugee children. Semi-structured interviews were conducted to understand the acceptability of this approach and standardised measures of PTSD were used to provide preliminary data regarding the effectiveness of NET for these clients. The clients attended NET consistently with few missed appointments. At post-treatment, two clients' symptom scores were below the clinical cut-off for PTSD and all three clients who completed NET met reliable improvement criteria. The clients reported improvements in functional outcomes and mentioned that they would encourage other young people with similar difficulties to engage in NET. This study was limited by the small sample size and naturalistic time limitations in clinicians' contracts. This article highlights that it is possible to implement NET within routine clinical practice and observed improvements in PTSD symptoms and functional outcomes for UAM.

Childhood Trauma and Psychosis: An Updated Review

There is growing evidence to support the link between childhood trauma and psychosis. Childhood trauma increases the risk for psychosis and affects severity and type of psychotic symptoms, and frequency of comorbid conditions, including depression and substance use. Childhood trauma is linked to more severe functional impairment in individuals with psychosis. There is evidence to support gender differences in the influence of childhood trauma on the course of psychotic illnesses, appearing to be more profound in girls and women. Other biological markers that may explain the link between childhood trauma and psychosis include brain-derived neurotrophic factor and other inflammatory markers.

Five Applications of Narrative Exposure Therapy for Children and Adolescents Presenting With Post-Traumatic Stress Disorders

Narrative exposure therapy (NET) is an individual therapeutic approach that has an emerging evidence base for children. It was initially trialed with refugee and asylum seeking populations, in low, middle and high-income settings, utilizing either lay or professional therapists. The results of treatment trials for PTSD in refugee children with NET (or the child "KIDNET" adaptation) demonstrates how this is an effective intervention, is scalable and culturally dexterous. This paper describes, in five cases from clinical practice settings, the applicability of NET into broader, routine practice. The cases outlined describe the use of NET with adolescents with: autism spectrum disorders, psychotic symptoms, and intellectual disabilities; histories of forced abduction into child soldiering; complex physical health problems needing multiple interventions; and victims of childhood sexual abuse. The cases are discussed with regards to how the NET lifeline facilitated engagement in treatment, practical adaptations for those with intellectual disabilities and how NET, with its relatively short training for health professionals, can be modified to different contexts and presentations. The importance of improving access to care is discussed to ensure that young people are supported with their most complex and disruptive memories.

The symptom representation of posttraumatic stress disorder in a sample of unaccompanied and accompanied refugee minors in Germany: a network analysis

Background: Given the unprecedented number of traumatized refugee minors in Europe and the increased prevalence of mental disorders such as PTSD in this vulnerable population, new methodologies that help us to better understand their symptomatology are crucial. Network analysis might help clinicians to both understand which symptoms might trigger other symptoms, and to identify relevant targets for treatment. However, to date only two studies have applied the network analysis approach to an (adult) refugee population and only three studies examined this approach in children and adolescents. Objective: The aim of this study is to explore the network structure and centrality of DSM-5 PTSD symptoms in a cross-sectional sample of severely traumatized refugee minors. Method: A total of N = 419 (M age = 16.3; 90.7% male) unaccompanied (79.9%) and accompanied (20.1%) refugee minors were recruited in five studies in southern Germany. PTSD symptoms were assessed using the Child and Adolescent Trauma Screen (CATS). The network was estimated using state-of-the-art regularized partial correlation models using the R-package qgraph. Results: The most central symptoms were nightmares, physiological and psychological reactivity, and concentration problems. The strongest connections between symptoms were established for psychological and physiological reactivity, irritability/anger and self-destructive/reckless behaviour, intrusions and nightmares, nightmares and sleep disturbance, and between concentrations problems and sleep disturbance. Conclusion: This study furnishes information relevant to research and the clinical management of PTSD in refugee minors, and also in terms of comparisons with trauma-exposed children and adolescents without a migration background. Re-experiencing symptoms seem to be central in the refugee minor PTSD profile and thus merit special consideration in the diagnostic and treatment evaluation process. Investigating the PTSD network longitudinally and complementing between-subject analyses with within-subject ones might provide further insight into the symptomatology of refugee minors and how to treat them successfully.

A systematic review and meta-analysis on the prevalence of depression in children and adolescents after exposure to trauma

BACKGROUND

Depression is often reported as co-occurring with post-traumatic stress disorder in children and adolescents, but its prevalence within trauma-exposed child and adolescent samples is not well understood.

METHODS

Our meta-analyses addressed two questions: I. What is the prevalence of depression (either based on structured interview or cut-off on a self-report measure) in children and adolescents after exposure to trauma? II. Does trauma exposure increase the severity or rates of depression comparative to another comparison group of children and adolescents with milder exposure or no exposure to trauma?

RESULTS

Fifty-six studies reported depression prevalence. A random effects meta-analysis suggested that 24.2% [95% CI 20.6-28.0] of children and adolescents exposed to a traumatic event met criteria for depression. Our second meta-analysis across 30 studies found that the effect of trauma exposure (relative to unexposed or less exposed children and adolescents) on depression scores was medium in size (d = 0.51, 95% CI 0.41-0.61). The odds of a diagnosis of depression were 2.6 times greater [95% CI 2.0-3.3] for children and adolescents exposed to trauma as compared to those unexposed or less exposed. Participants exposed to interpersonal violence (IPV) had a higher prevalence and level of depression compared with those exposed to non-IPV trauma.

LIMITATIONS

Results should be interpreted with caution due to high levels of heterogeneity.

CONCLUSION

Depression in trauma-exposed children and adolescents is a common response to trauma that is not solely reflective of pre-traumatic difficulties. Post-traumatic depression merits serious consideration in trauma-exposed children and adolescents.

Editorial: The psychopathology p factor: will it revolutionise the science and practice of child and adolescent psychiatry?

The psychopathology p factor has emerged from a series of strong empirical studies, largely in the adult psychiatry literature. Here, some of the recent findings relating to the p factor in children and adolescents are considered and the implications for child and adolescent psychiatry are discussed. Is it essential to covary for 'p' when we study specific domains of psychopathology? Do neurodevelopmental conditions make up part of the psychopathology p factor? How do we treat the 'p factor' in clinics? This editorial considers some of the contributions from this issue of Journal of Child Psychology and Psychiatry together with the wider literature that speak to these issues.
