Two approaches to the diagnosis of posttraumatic stress disorder in infancy and early childhood

Child sexual abuse versus adult sexual assault: A review of psychological and neurobiological sequelae

Sexual trauma (ST) occurs with alarming frequency in the United States (U.S.) in the form of both childhood sexual abuse (CSA) and adulthood sexual assault (ASA). It is well-established that the effects of ST are pervasive, and that ST can be a risk factor for the development of several psychiatric disorders. However, the potential for distinct psychological consequences or neural correlates between CSA and ASA has received little attention. Furthermore, despite the high prevalence of sexual revictimization, the combinatorial effects of CSA and ASA are understudied in comparison to each form of ST on its own. In the current review, we present results from both clinical psychology and neuroscience research on the impacts of CSA and ASA, describing major psychological, biopsychosocial, and neuroimaging findings for each form of ST. We further highlight limitations in the current state of the research and needed areas of future research to better understand the distinct, overlapping, and cumulative effects of ST in both childhood and adulthood. The present study summarizes the state of the literature on this critical form of trauma and provides recommendations for future clinical research practices to mitigate the deleterious outcomes of ST.

Toward a Developmental Model of Continuity and Change in PTSD Symptoms following Exposure to Traumatic and Adverse Experiences

A developmental understanding of the expression of posttraumatic stress (PTS) symptoms following trauma in childhood requires identifying continuity and change in not just overall symptoms but in the individual symptoms as well. Such models of change also require understanding multiple dimensions of time. That is, longitudinal change-the passage of time-may have different effects on symptom expression depending on when in time an individual entered the study - such as what age they were when first assessed. This paper addresses these ideas with an overview of the developmental differences in the assessment of PTS from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, (DSM-5), longitudinal research on posttraumatic stress disorder (PTSD) symptoms, and providing synthesis within a symptom network perspective. We then provide an illustration of how individual PTSD symptoms change over time at different ages (elementary versus middle school) with a secondary analysis of data from a previously reported study (n = 191 youth, aged 8-15, assessed at two time points six months apart). The reanalysis of the data suggests both continuity and change in symptoms over time (i.e., some symptoms were more stable than other symptoms) with differences in symptom rates and their longitudinal change as a function of age (i.e., some symptoms more common or more stable in younger versus older or older versus younger). We close with avenues for future research aimed at better understanding symptom cascades over time and at different ages and potential implications for future iterations of assessment/classification systems.

[The Requirement of a Situated Approach in the Treatment of Preschool Children with a Refugee Background: Discussion of a Case Study]

In recent years, increasingly more German-born preschool children of refugee parents have been referred to the 'specialized consultation service for refugee minors' of the Department of Child and Adolescent Psychiatry at the University Hospital Münster. This 'change' in the use of the above-mentioned consultation service could be understood as a 'natural' consequence of the family life cycle of forced migrants who some years ago came to Germany as adolescents or young adults and started here a family. The treatment of 'preschoolers with a refugee background', as we may call this group of patients, confronts mental health practitioners with particular challenges. In this contribution, we specify some of these challenges and argue that, due to the deep intertwinement of different aspects of these patients' condition, a 'situated approach' is required when treating this population.When planning therapeutic interventions for preschoolers with refugee background, their families should be conceived as unified systems which in their social and transcultural embeddedness exhibit trans-individual vulnerabilities and resources. By discussing a case study, we illustrate how an extremely challenging child psychiatric treatment could succeed only on the condition that we focused on the interconnectedness of various factors determining not merely the patient's symptomatic behavior but, furthermore, the behavior of the family, i. e., on the condition of focusing on the situated nature of the problematic.

Postoperative opioid administration and post-traumatic stress symptoms in preschool children after cardiac surgery

PURPOSE

The purpose of this study was to explore relationships between postoperative opioid administration and posttraumatic stress symptoms (PTSS) in preschool-aged children surviving cardiac surgery.

DESIGN AND METHODS

This was a cross-sectional, descriptive study using survey administration and medical chart review. Primary caregivers of children aged three to six years who underwent cardiac surgery at our institution between 2018 and 2020 were invited to participate. Opioid administration was calculated according to morphine milligram equivalents and indexed to the child's body weight. Caregivers completed the Young Child Posttraumatic Stress Disorder Checklist to explore child PTSS. We used correlational methods to assess the strength and direction of relationships between postoperative opioid administration and child PTSS.

RESULTS

We did not find a statistically significant relationship between total postoperative opioid administration and child PTSS. When analyzing individual opioid agents, morphine did show a significant inverse relationship to YCPC scores (r_s = -.57, p = .017) in children with single ventricle physiology.

CONCLUSIONS

Total postoperative opioid administration was not statistically significantly related to child PTSS in our sample. Differing patterns of association were noted among children with single- versus bi-ventricular physiology. Postoperative morphine administration was favorably associated with PTSS in children with single-ventricle physiology.

PRACTICE IMPLICATIONS

Nurses caring for preschool children who undergo cardiac surgery should anticipate the potential development of PTSS in their patients. Studies using larger sample sizes and longitudinal design are needed to replicate the significant relationship between morphine administration and PTSS in preschoolers with single-ventricle physiology.

Systematic Review and Meta-analysis: Prevalence of Posttraumatic Stress Disorder in Trauma-Exposed Preschool-Aged Children

OBJECTIVE

Trauma exposure is common in preschool-aged children. Understanding the psychological impact of such exposure and the prevalence of posttraumatic stress disorder (PTSD) in this population is important for provision of appropriate and timely intervention. This pre-registered (PROSPERO: CRD41019133984) systematic review and meta-analysis examined the prevalence of PTSD in trauma-exposed preschool-aged children.

METHOD

Literature searches were conducted of PubMed (Medline), PsycINFO and PILOTS, alongside reference lists of relevant reviews. Studies were selected if they comprised trauma-exposed samples with a mean age of less than 6.5 years, and PTSD was assessed using standardized interviews at least 1-month post trauma. Information on sample characteristics, trauma exposure, PTSD measurement, and diagnostic criteria were extracted. For studies that applied more than one PTSD diagnostic algorithm, the most age-appropriate criteria were used to estimate pooled prevalence estimate across studies. A random-effects model was used for meta-analysis.

RESULTS

Eighteen studies were included (N = 1941). The pooled PTSD prevalence was 21.5% (95% CI = 13.8%-30.4%) when using the most developmentally appropriate diagnostic algorithm that was available. When focusing on the subset of studies that reported both standard adult criteria and age-appropriate criteria (k = 12), a pooled estimate of 4.9% (95% CI = 2.5%-8.0%) was obtained for standard adult criteria (DSM-IV), and 19.9% (95% CI = 12.1%-29.0%) was obtained for age-appropriate criteria (PTSD-AA). Prevalence was 3-fold higher following interpersonal and repeated trauma exposure, compared to non-interpersonal or single-event trauma, respectively. Higher prevalence was found when age-appropriate diagnostic tools were used. There was significant heterogeneity across studies and a lack of studies conducted in low-income countries and applying age-appropriate diagnostic algorithms.

CONCLUSION

Preschool-aged children are vulnerable to developing PTSD following trauma exposure. Younger children show prevalence trends similar to those of older youths and adults following different types of trauma. Age-appropriate diagnostic criteria are essential to ensure that appropriate identification and early support are provided.

The use of biomarkers associated with leaky gut as a diagnostic tool for early intervention in autism spectrum disorder: a systematic review

Background

Innovative research highlighted the probable connection between autism spectrum disorder (ASD) and gut microbiota as many autistic individuals have gastrointestinal problems as co-morbidities. This review emphasizes the role of altered gut microbiota observed frequently in autistic patients, and the mechanisms through which such alterations may trigger leaky gut.

Main body

Different bacterial metabolite levels in the blood and urine of autistic children, such as short-chain fatty acids, lipopolysaccharides, beta-cresol, and bacterial toxins, were reviewed. Moreover, the importance of selected proteins, among which are calprotectin, zonulin, and lysozyme, were discussed as biomarkers for the early detection of leaky gut as an etiological mechanism of ASD through the less integrative gut–blood–brain barriers. Disrupted gut–blood–brain barriers can explain the leakage of bacterial metabolites in these patients.

Conclusion

Although the cause-to-effect relationship between ASD and altered gut microbiota is not yet well understood, this review shows that with the consumption of specific diets, definite probiotics may represent a noninvasive tool to reestablish healthy gut microbiota and stimulate gut health. The diagnostic and therapeutic value of intestinal proteins and bacterial-derived compounds as new possible biomarkers, as well as potential therapeutic targets, are discussed.

Examining the 8-Year Trajectory of Posttraumatic Stress Symptoms in Children Exposed to Intimate Partner Violence

Millions of children witness intimate partner violence (IPV) each year, and the effects of these experiences are substantial. One of the more common sequelae of exposure to IPV is the development of posttraumatic stress symptoms (PTSS). Given the chronic nature of both IPV and PTSS, there is a need for prospective research on long-term mental health outcomes following IPV exposure in childhood. This study prospectively examines trajectories of PTSS over an 8-year period, beginning from the preschool period. This study also investigates factors that may be associated with these trajectories, including intervention participation, continued IPV exposure, and the caregiving environment. A total of 120 mother-child dyads participated in four study waves over an 8-year period, beginning when children were between the ages of 4 and 6. Mothers and children participated in an intervention between baseline and Time 2. At the onset of the study, all mothers reported experiencing IPV over the previous year. Findings demonstrate that, in general, children experienced worsening of their PTSS over the 8-year trajectory, and few factors were significantly associated with this trajectory. There were no associations between intervention participation, parenting behaviors, and long-term child PTSS outcomes; however, there were significant associations between amount of IPV exposure, mother's level of PTSS, and children's PTSS outcomes. These results underscore the need to better understand the impact of early-life exposure to IPV, as well as the need for interventions tailored to this developmental period. Furthermore, these findings highlight the long-term negative associations between chronic exposure to IPV and child well-being, as well as the significant connections between caregiver and child mental health.

The Trauma Symptom Checklist for Young Children: A Psychometric Review

The Trauma Symptom Checklist for Young Children (TSCYC) is a 90-item caregiver-report measure of childhood traumatic stress and abuse-related experiences in children, ages three to twelve years old.

PURPOSE

The objective of this review is to examine the current empirical evidence (n = 22) regarding the psychometric properties of the TSCYC.

METHOD

A variety of study designs were reviewed for psychometric evidence supporting the reliability and validity of the TSCYC.

RESULTS

The psychometric evidence for the TSCYC indicates it is a reliable scale. However, evidence of validity is moderate and focuses on older children.

DISCUSSION

Clinicians may utilize the TSCYC to support a PTSD diagnosis in children. Further psychometric exploration would strengthen the body of evidence for younger children (ages 3-5) who have had traumatic experiences.

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

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

Age-related similarities and differences in networks of acute trauma-related stress symptoms in younger and older preschool children

BACKGROUND

Prior research on trauma-exposed preschool children has found various levels of trauma-related stress symptoms depending on age, which might be explained by developmental factors.

OBJECTIVE

This study uses network analysis to extend prior research and compare symptom presentation in younger and older preschoolers in the acute phase (first 4 weeks) following a potentially traumatic event.

METHOD

Parent-reported trauma-related acute stress symptoms were assessed using the Pediatric Emotional Distress Scale - Early Screener via www.kidtrauma.com. First, the overall symptom severity and symptom levels were compared between younger (1-3 years) and older (4-6 years) preschoolers. Further, two Gaussian graphical models of stress symptoms in younger (n = 242; M_age = 2.3 years; SD_age = 0.6 years) and older preschoolers (n = 299; M_age = 4.8 years; SD_age = 0.7 years) were modelled and compared.

RESULTS

Overall symptom severity did not differ between the groups. Symptom levels for developmental regression and avoidance of talking about the event were higher in older preschoolers. The network structures of the younger and the older preschoolers were largely similar. Highly central symptoms in both networks were trauma-unrelated fear and anger. The connections between fear of reminders and clinginess and trauma-unrelated fear and clinginess were stronger in the older preschoolers' network. The connections between worry and sadness and withdrawal; fear of reminders and creation of games, stories, and pictures; and whininess and clinginess were all stronger in the younger preschoolers' network.

CONCLUSIONS

Trauma-related stress symptomatology of younger and older preschoolers may not differ greatly in the acute phase. Trauma-unrelated fear and anger seem to be central symptoms in both groups. However, examining symptom-level associations across age groups revealed differential connections that might arise from developmental differences. If replicated in longitudinal and within-subject studies, these findings could help tailor interventions for trauma-exposed preschoolers in the acute phase.

The Dimensionality of Proposed DSM-5 PTSD Symptoms in Trauma-Exposed Young Children

A subtype of the posttraumatic stress disorder diagnosis for children 6 years and younger (PTSD-6Y) was introduced in the Diagnostic and Statistical Manual, Fifth Edition (DSM-5). This study utilized confirmatory factor analytic techniques to evaluate the proposed DSM-5 PTSD-6Y factor structure and criterion and convergent validity against competing models. Data for N = 284 (3–6 years) trauma-exposed young children living in New Orleans were recruited following a range of traumas, including medical emergencies, exposure to Hurricane Katrina and repeated exposure to domestic violence. The model was compared to DSM-IV, a 4-factor ‘dysphoria’ model that groups symptoms also associated with anxiety and depression, and alternate 1- and 2- factor models. Convergent validity was established against the Child Behavior Checklist (CBCL). Criterion related validity was established by comparing each model to a categorical rating of impairment. The Dysphoria and PTSD-6Y models offered the better accounts of symptom structure, although neither satisfied minimum requirements for a good fitting model. These two models also only showed small levels of convergence with CBCL dimensions. The 1-factor model offered the most compelling balance of sensitivity and specificity, with the 2-factor model and the Dysphoria model following closely behind. These CFA results do not support the symptom clusters proposed within the DSM-5 for PTSD-6Y. Although a 4-factor Dysphoria model offers a better overall account of clustering patterns (relative to alternate models), alongside acceptable sensitivity and specificity for detecting clinical impairment, it also falls short of being an adequate model in this younger age group.

Riemannian classifier enhances the accuracy of machine-learning-based diagnosis of PTSD using resting EEG

Recently, objective and automated methods for the diagnosis of post-traumatic stress disorder (PTSD) have attracted increasing attention. However, previous studies on machine-learning-based diagnosis of PTSD with resting-state electroencephalogram (EEG) have reported poor accuracies of as low as 60%. Here, a Riemannian geometry-based classifier, the Fisher geodesic minimum distance to the mean (FgMDM), was employed for PTSD classification for the first time. Eyes-closed resting-state EEG data of 39 healthy individuals and 42 PTSD patients were used for the analysis. EEG source activities in 148 cortical regions were parcellated based on the Destrieux atlas, and their covariances were evaluated for each individual. Thirty epochs of preprocessed EEG were employed to calculate source activities. In addition, the FgMDM approach was applied to each EEG source covariance to construct the classifier. For a comparison, linear discriminant analysis (LDA), support vector machine (SVM), and random forest (RF) classifiers employing source band powers and network features as feature candidates were also tested. The FgMDM classifier showed an average classification accuracy of 75.240.80%. In contrast, the maximum accuracies of LDA, SVM, and RF classifiers were 66.54 ± 2.99%, 61.11 ± 2.98%, and 60.99 ± 2.19%, respectively. Our study demonstrated that the diagnostic accuracy of PTSD with resting-state EEG could be significantly improved by employing the FgMDM framework, which is a type of Riemannian geometry-based classifier.

Post-traumatic stress disorder and related factors in students whose school burned down: Cohort study

AIMS

This research examines the prevalence of post-traumatic stress disorder (PTSD) and its related factors in students whose school burned down, one month and six months after the incident.

METHODS

A total of 56 students from grades one through six were invited to participate in this study with permission from their parents. Subjects were screened for PTSD by using UCLA PTSD Reaction Index (DSM-5 Version) during three periods: 1, 6, and 12 months after the incident. Children diagnosed with PTSD were interviewed by a child and adolescent psychiatrist to confirm their diagnosis and obtain related factors. Percentage and logistic regression were used for statistical evaluation. 5 out of the 56 students (8.9 %) had PTSD one month after the incident, 2 of them recovered after six months. 6 out of 56 students (10.7 %) had PTSD at six months and 2 of 40 (5%) had PTSD at one year after the incident. Students who lived in the school's dorms had significantly more PTSD than those who lived elsewhere, p < 0.01, RR = 5.16 (4.04-6.6). After one year, age was the only factor related to PTSD (p = 0.01, odds ratio = 0.452).

CONCLUSION

Post-traumatic stress disorder is a common disorder in children after a disaster. Although some can recover shortly after an incident, others develop symptoms one month after the incident. Age is a risk factor that can lead to the development of PTSD.

Posttraumatic stress disorder and psychosocial difficulties among children living in a conflict area of the Southeastern Anatolia region of Turkey

BACKGROUND

Traumatic events and armed conflicts can lead to many mental disorders, especially posttraumatic stress disorder (PTSD), in children. We investigated the PTSD symptoms, psychosocial difficulties, general health levels of the parents, and direct and indirect effects of trauma on psychological outcomes.

MATERIALS AND METHODS

A total of 482 children were included in the study. Two hundred and eight of those children were from Derik district, where street fights, curfews, and conflict have been experienced, and 274 of those children were from Yeşilli district, where no conflicts have been observed despite being in the same province. All children filled out the child posttraumatic stress disorder reaction index, the strengths and difficulties questionnaire (SDQ), and parents filled out the General Health Questionnaire-12 (GHQ).

RESULTS

All children showed moderate PTSD symptoms; however, no significant difference was observed between the two groups. In the exposed group, children, who had to leave their homes for a while due to conflicts, had worse PTSD symptoms, higher SDQ difficulty scores, and parents' GHQ scores. It was determined that being a female having high maternal GHQ scores and leaving home due to the conflicts significantly increase the risk of occurrence of trauma symptoms.

CONCLUSION

Our findings suggest that children are susceptible to the direct and indirect effects of trauma. It is crucial for intervention programs to be developed for the detection, prevention, and treatment of PTSD symptoms to be applied to all children, regardless of exposure type, in areas affected by conflict.

Applications of the Chinese version of the primary care PTSD screen for DSM-5 (PC-PTSD-5) for children

BACKGROUND

Effective screening is important for public mental health services. Although the primary care PTSD screen for DSM-5 (PC-PTSD-5) is useful in screening for post-traumatic stress disorder (PTSD) in adults, its reliability and validity for use in children remain unclear. This study aimed to examine the performance characteristics of the Chinese PC-PTSD-5 for children in children aged 8 to 16 years.

METHODS

4,022 rural children from Grades 4 to 9 in China were included in this study. All participants were assessed for PTSD using the Chinese PC-PTSD-5 for children and the PTSD Checklist for DSM-5 (PCL-5), and assessed for anxiety using the Chinese version of the State Anxiety Scale for Children (CSAS-C), and for depression using the Children's Depression Inventory - Short Form (CDI-S). The performance characteristics of the PC-PTSD-5 for children were evaluated using receiver operating characteristic analyses.

RESULTS

The mean scores on the PCL-5 and the PC-PTSD-5 were 17.45 (SD = 14.78) and 1.78 (SD = 1.33), respectively. There was a significant correlation between the PC-PTSD-5 and PCL-5 (r = 0.54, p < 0.001), and small but significant correlations of the PC-PTSD-5 with the CSAS-C (r = 0.31, p < 0.001) and CDI-S (r = 0.27, p < 0.001). In this study, 2 and 3 were both found to be acceptable cutoff values. A cutoff value of 2 yielded a sensitivity of 0.87 and a specificity of 0.52, while a cutoff of 3 had sensitivity = 0.57, and specificity = 0.77.

LIMITATIONS

A clinical interview was not used to validated diagnostic findings.

CONCLUSIONS

The reliability and validity of the Chinese PC-PTSD-5 were statistically acceptable for screening for probable PTSD in children. Additionally, the Chinese PC-PTSD-5 had a favorable sensitivity at a cut off 2 and a favorable specificity at a cut off 3, based on PCL-5 results.

Validation of the Diagnostic Infant and Preschool Assessment in a Danish, trauma-exposed sample of young children

Background:

There exist only few developmentally sensitive assessment instruments for identifying posttraumatic stress disorder (PTSD) and other potentially comorbid affective and behavioral symptomatology in preschool children. Consequently, young children who exhibit post-trauma symptomatology risk not being identified and not receiving the appropriate treatment. One of the few instruments that exist is the Diagnostic Infant and Preschool Assessment (DIPA).

Objective:

To examine internal reliability and convergent validity of the Danish version of the DIPA, a semi-structured interview of caregivers about their child’s mental health.

Method:

In total, 62 caregivers of trauma-exposed children aged 1-6 years were interviewed with the DIPA and completed the Strengths and Difficulties Questionnaire (SDQ).

Results:

The children had experienced between one and eight traumas (Mdn = 3). Based on the DIPA, 48.4% of the children exhibited PTSD. The DIPA showed good to excellent internal consistency for the disorders of major depressive disorder, attention deficit hyperactivity disorder, oppositional defiant disorder, separation anxiety disorder and overall internal consistency of PTSD and reactive attachment disorder. Internal consistency was lower for each symptom cluster of PTSD and the overall consistency of sleep disorder with Cronbach’s alpha ranging between 0.54 and 0.69. Correlations between continuous scores of eight disorders of the DIPA and SDQ scales provided support for convergent validity of the DIPA.

Conclusion:

The study provides preliminary evidence to support the Danish version of DIPA as a valid measure of symptoms of young children exposed to psychological trauma. As a standardized assessment tool, the DIPA can aid in early and structured assessment of young children exposed to trauma and can help guide treatment for those in need.

The importance of the DSM-5 posttraumatic stress disorder symptoms of cognitions and mood in traumatized children and adolescents: two network approaches

BACKGROUND

The aim of this study is to provide a better understanding of the central symptoms of DSM-5 posttraumatic stress disorder (PTSD) in children and adolescents from the perspective of the child and its caregiver. Identifying core symptoms of PTSD can help clinicians to understand what may be relevant targets for treatment. PTSD may present itself differently in children and adolescents compared to adults, and no study so far has investigated the DSM-5 PTSD conceptualization using network analysis.

METHODS

The network structure of DSM-5 PTSD was investigated in a clinical sample of n = 475 self-reports of children and adolescents and n = 424 caregiver-reports using (a) regularized partial correlation models and (b) a Bayesian approach computing directed acyclic graphs (DAGs).

RESULTS

(a) The 20 DSM-5 PTSD symptoms were positively connected within the self-report and the caregiver-report sample. The most central symptoms were negative trauma-related cognitions and persistent negative emotional state for the self-report and negative trauma-related cognitions, intrusive thoughts or memories and exaggerated startle response for the caregiver-report. (b) Similarly, symptoms in the negative alterations in cognitions and mood cluster (NACM) have emerged as key drivers of other symptoms in traumatized children and adolescents.

CONCLUSIONS

As the symptoms in the DSM-5 NACM cluster were central in our regularized partial correlation networks and also appeared to be the driving forces in the DAGs, these might represent important symptoms within PTSD symptomatology and may offer key targets in PTSD treatment for children and adolescents.

PTSD in Children Below the Age of 6 Years

PURPOSE OF REVIEW

This review summarizes the latest evidence and developments in the validation of PTSD diagnostic criteria for children 6 years and under (PTSD<6Y), discusses the limitations of the current diagnostic criteria, and highlights areas for future research.

RECENT FINDINGS

Research has found that the DSM-5 PTSD<6Y, and a similar version in the DC:0-5, currently provides the most developmentally sensitive classification of PTSD for young children. In contrast, preliminary evidence suggests that the ICD-11 criteria might not appropriately capture PTSD in young children. The inclusion of PTSD<6Y, the first developmental subtype in the DSM-5, represents an important step towards having a diagnostic system that is developmentally sensitive and relevant across the life span. However, further validation work and research with regard to the definition of trauma and functional impairment as well as with the age-appropriate description of symptoms is needed, especially in the youngest age group (0-3 years).

Posttraumatic Stress Disorder in Very Young Children: Diagnostic Agreement Between ICD-11 and DSM-5

The prevalence of posttraumatic stress disorder (PTSD) in very young children depends on the diagnostic criteria. Thus far, studies have investigated the International Classification of Diseases (11th rev.; ICD-11) criteria for PTSD only in samples of children older than 6 years of age. The aim of this study was to test the diagnostic agreement between the ICD-11 and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for children who are 6 years old and younger. Caregivers of children aged 3-6 years in foster care in Germany (N = 147) and parents of children aged 1-4 years who had attended a hospital in Switzerland following burn injuries (N  = 149) completed a questionnaire about children's PTSD. Rates of PTSD were calculated according to ICD-11 (considering a specific and a more general conceptualization of intrusive memories) and DSM-5 criteria and were compared using McNemar's tests and Cohen's kappa. The proportion of children who met the ICD-11 criteria was 0.6-25.8% lower than the proportion of PTSD cases according to the DSM-5 criteria. The diagnostic agreement between each ICD-11 algorithm and DSM-5 was moderate, κ = 0.52-0.66. A systematic investigation of adaptions of the ICD-11 avoidance cluster identified alternative symptom combinations leading to higher agreement with the DSM-5 requirements. Furthermore, DSM-5 had higher predictive power for functional impairment than the ICD-11 algorithms. In conclusion, the findings suggest that the ICD-11 criteria show less sensitivity in very young children, which can be explained by the more stringent avoidance cluster.

Research domain criteria and the study of trauma in children: Implications for assessment and treatment research

By definition, the Diagnostic and Statistical Manual (DSM) diagnosis of posttraumatic stress disorder (PTSD) requires exposure to a traumatic event. Yet, the DSM diagnostic requirements for children and adolescents for PTSD may fail to capture traumatized youth with significant distress and functional impairment. Many important studies have utilized PTSD diagnosis as a mechanism for grouping individuals for comparative studies examining brain functioning, neuroendocrinology, genetics, attachment, and cognition; however, focusing only on those with the diagnosis of PTSD can miss the spectrum of symptoms and difficulties that impact children who experience trauma and subsequent impairment. Some studying child trauma have focused on examining brain and biology of those with exposure and potential impairment rather than only those with PTSD. This line of inquiry, complementary to PTSD specific studies, has aided our understanding of some of the changes in brain structure and neuroregulatory systems at different developmental periods following traumatic exposure. Application of the Research Domain Criteria (RDoC) framework proposed by NIMH to the study of child trauma exposure and subsequent impairment is an opportunity to examine domains of function and how they are impacted by trauma. Research to date has focused largely in the areas of negative valence, regulatory, and cognitive systems, however those studying complex or developmental trauma have identified an array of domains that are impacted which map onto many of the RDoC categories. This paper will review the relevant literature associated with child trauma as it relates to the RDoC domains, outline areas of needed research, and describe their implications for treatment and the advancement of the field.

Dealing With the Aftermath of Mass Disasters: A Field Study on the Application of EMDR Integrative Group Treatment Protocol With Child Survivors of the 2016 Italy Earthquakes

This study explored the effects of the EMDR Integrative Group Treatment Protocol (EMDR-IGTP) on child survivors of the earthquakes that struck Umbria, a region of central Italy, on August 24th and on October 26th 2016. Three hundred and thirty-two children from the town of Norcia and nearby severely disrupted villages received 3 cycles of EMDR-IGTP. The Emotion Thermometers (ET-5) and the Children's Revised Impact of Event Scale (CRIES-13) were administered before (T0) and about 1 week after the conclusion of the third cycle (T3) of EMDR-IGTP. At T3, older children showed a reduction of distress and anger, whereas younger children reported an increase on these domains; moreover, older children reported a greater reduction of anxiety than younger ones. A greater reduction of distress, anxiety, and need for help was evidenced in females, whereas a greater improvement in depressive symptoms was evidenced in males. The effects of the EMDR-IGTP treatment on post-traumatic symptoms were particularly evident in older children, compared to younger ones, and marginally greater in females than in males; moreover, a greater improvement was found in children who had received a timelier intervention, than in those who received delayed treatment. These results provide further evidence for the utility of EMDR-IGTP in dealing with the extensive need for mental health services in mass disaster contexts. Also, these data highlight the importance of providing EMDR-IGTP in the immediate aftermath of a natural disaster, to contribute significantly in restoring adaptive psychological functioning in children, especially in older ones.

Posttraumatic Stress Symptoms in Preschool Children in Foster Care: The Influence of Placement and Foster Family Environment

Children in foster care often experience traumatic events which increase their risk for posttraumatic stress symptoms (PTSS). Until now, no research has investigated the developmentally sensitive PTSS criteria for preschoolers among children in foster care. The current study estimated the prevalence of potentially traumatic experiences and clinical PTSS in German foster care children aged 3 to 7 years. The foster parents of 324 children completed questionnaires about children's PTSS, foster parental stress, parenting, and family functioning. Linear regression models tested trauma-related variables, placement history, and foster family characteristics as predictors of PTSS. Approximately 45.4% of the foster children had experienced at least one traumatic event and 15.4% had clinical PTSS. Physical abuse, β = .34, p < .001; hospitalization, β = -.17, p = .026; witnessing someone being hurt, β = -.15, p = .047; and parental stress, β = .43, p < .001, were significantly associated with PTSS. Results demonstrate the impact the foster family has on children who are coping with trauma, and suggest the necessity of trauma-sensitive trainings for foster parents, with stress management as an important component.

Evaluating Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Posttraumatic Stress Disorder Diagnostic Criteria in Older Children and Adolescents

OBJECTIVES

Few studies have assessed how the diagnostic criteria for posttraumatic stress disorder (PTSD) apply to older children and adolescents. With the introduction of a new, developmentally sensitive set of criteria for very young children (age 6 years and younger) in Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), this raises new questions about the validity of the criteria for older children and adolescents. The current study investigated how diagnostic changes in DSM-5 impact diagnosis rates in 7-18-year olds.

METHODS

PTSD, impairment, and comorbid psychopathology were assessed in 135 trauma-exposed, treatment-seeking participants. Children (ages 7-12) were examined separately from adolescents (ages 13-18) to assess for potential developmental differences.

RESULTS

A significantly higher proportion of 7-12-year-old children met criteria for DSM-5 diagnosis (53%) compared to Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) (37%). However, among 13-18-year-old adolescents, the proportions diagnosed with DSM-5 (73%) and DSM-IV (74%) did not differ. Participants who met criteria for DSM-5 only (17%) did not differ from those diagnosed with DSM-IV in terms impairment or comorbidity. Using the newly accepted age 6 years and younger criteria resulted in a significantly higher proportion of 7-12-year-old (but not 13-18-year olds) children meeting criteria compared to DSM-IV or DSM-5. However, these children showed less impairment and comorbidity than those diagnosed with DSM-IV.

CONCLUSION

These findings suggest that DSM-5 criteria may be more developmentally sensitive than DSM-IV criteria, and may lead to higher prevalence rates of PTSD for 7-12-year-old children, but not for adolescents. Using the very young children criteria for 7-12-year-old children may further increase prevalence, but capture children with less severe psychopathology.

Translating the Cognitive Model of PTSD to the Treatment of Very Young Children: A Single Case Study of an 8-Year-Old Motor Vehicle Accident Survivor

Posttraumatic stress disorder (PTSD) is a clinical condition that occurs after a discrete traumatic event, such as an accident or assault. Research into PTSD has primarily been adult-focused; however, there is a growing body of evidence evaluating the theory and treatment of PTSD in young children. Consequently, cognitive behavior therapy (CBT) interventions for PTSD in youth have been developed that focus on 3 core components of the cognitive model-a disorganized memory of the trauma, maladaptive appraisals of the trauma and its effects (meanings), and dysfunctional coping mechanisms (management). Here, we describe the extension of this treatment approach (termed CBT-3M) to very young children (3-8 years) through the case of Dylan, an 8-year-old motor vehicle accident survivor. This serves as an illustration of the underlying theory and its successful application. Further work is intended to provide evidence of the efficacy of this treatment via an ongoing treatment trial.

The Effects of Exposure to Community Violence upon Latina Mothers and Preschool Children

Community violence is a stressor experienced by children and their parents. This exploratory study examines the psychological and behavioral effects of exposure to community violence on a sample of 31 Latina mothers and their children enrolled in a Head Start program. Based on maternal reports, the mother-child dyads have substantial exposure to community violence. Also, mothers exposed to community violence manifest significant levels of distress symptomatology (post-traumatic stress disorder [PTSD], depression, and anxiety). Multiple regression analyses reveal that maternal distress symptomatology acts as a mediator of child behavioral problems. These findings highlight that maternal distress symptomatology is more important than community violence exposure in contributing to heightened child behavior problems. Schools and mental health practitioners should assess for parents’ exposure to community violence.

Symptoms of Post-Traumatic Stress Disorder Among Young Children 2 Years After the Great East Japan Earthquake

OBJECTIVE

The aim of this study was to investigate the prevalence of post-traumatic stress disorder (PTSD) and its association with each traumatic experience among 5- to 8-year-old children 2 years after the Great East Japan Earthquake.

METHOD

Children ages 5-8 years who were in selected preschool classes on March 11, 2011, in 3 prefectures affected by the earthquake and 1 prefecture that was unaffected, participated in the study (N=280). PTSD symptoms were assessed through questionnaires completed by caregivers and interviews by psychiatrists or psychologists conducted between September 2012 and May 2013 (ie, 1.5-2 years after the earthquake).

RESULTS

Among children who experienced the earthquake, 33.8% exhibited PTSD symptoms. Of the different traumatic experiences, experiencing the earthquake and the loss of distant relatives or friends were independently associated with PTSD symptoms; prevalence ratios: 6.88 (95% confidence interval [CI]: 2.06-23.0) and 2.48 (95% CI: 1.21-5.08), respectively.

CONCLUSION

Approximately 1 in 3 young children in the affected communities exhibited PTSD symptoms, even 2 years after the Great East Japan Earthquake. These data may be useful for preventing PTSD symptoms after natural disasters and suggest the importance of providing appropriate mental health services for children.

Traumatic Childhood Events and Autism Spectrum Disorder

Traumatic childhood events are associated with a wide range of negative physical, psychological and adaptive outcomes over the life course and are one of the few identifiable causes of psychiatric illness. Children with autism spectrum disorder (ASD) may be at increased risk for both encountering traumatic events and developing traumatic sequelae; however, this topic has been understudied. This review considers the rationale for examining traumatic events and related symptomology in individuals with ASD and summarizes the limited research on this topic. A conceptual framework for understanding the interplay of ASD, trauma and traumatic sequelae is proposed and recommendations for future research presented.

Effectiveness of medical hypnosis for pain reduction and faster wound healing in pediatric acute burn injury: study protocol for a randomized controlled trial

BACKGROUND

Burns and the associated wound care procedures can be extremely painful and anxiety-provoking for children. Burn injured children and adolescents are therefore at greater risk of experiencing a range of psychological reactions, in particular posttraumatic stress disorder, which can persist for months to years after the injury. Non-pharmacological intervention is critical for comprehensive pain and anxiety management and is used alongside pharmacological analgesia and anxiolysis. However, effective non-pharmacological pain and anxiety management during pediatric burn procedures is an area still needing improvement. Medical hypnosis has received support as a technique for effectively decreasing pain and anxiety levels in adults undergoing burn wound care and in children during a variety of painful medical procedures (e.g., bone marrow aspirations, lumbar punctures, voiding cystourethrograms, and post-surgical pain). Pain reduction during burn wound care procedures is linked with improved wound healing rates. To date, no randomized controlled trials have investigated the use of medical hypnosis in pediatric burn populations. Therefore this study aims to determine if medical hypnosis decreases pain, anxiety, and biological stress markers during wound care procedures; improves wound healing times; and decreases rates of traumatic stress reactions in pediatric burn patients.

METHODS/DESIGN

This is a single-center, superiority, parallel-group, prospective randomized controlled trial. Children (4 to 16 years, inclusive) with acute burn injuries presenting for their first dressing application or change are randomly assigned to either the (1) intervention group (medical hypnosis) or (2) control group (standard care). A minimum of 33 participants are recruited for each treatment group. Repeated measures of pain, anxiety, stress, and wound healing are taken at every dressing change until ≥95 % wound re-epithelialization. Further data collection assesses impact on posttraumatic stress symptomatology, speed of wound healing, and parent perception of how easy the dressing change is for their child.

DISCUSSION

Study results will elucidate whether the disease process can be changed by using medical hypnosis with children to decrease pain, anxiety, and stress in the context of acute burn wounds.

Preschool Israeli Children Exposed to Rocket Attacks: Assessment, Risk, and Resilience

Preschool children are among the most vulnerable populations to adversity. This study described the effects of 4 weeks of daily exposure to rocket attacks on children living on Israel's southern border. Participants enrolled in this study were 122 preschool children (50% boys) between the ages 3 and 6 years from 10 kindergartens. We assessed mothers' report of children's symptoms according to the DSM-IV and alternative criteria resembling the DSM-5 criteria for posttraumatic stress disorder (PTSD), general adaptation, traumatic exposure, and stressful life events 3 months after the war. The prevalence of PTSD was lower when the diagnosis was derived from the DSM-IV (4%) than from the DSM-5 criteria (14%). Mothers of children with 4 or more stressful life events reported more functional impairment in social, occupational, and other important areas of functioning compared to children with 0 or 1 stressful life event. Children with more severe exposure showed more severe symptoms and mothers had more concerns about the child's functioning (η(p)(2) = .09-.25). Stressful life events and exposure to traumatic experiences accounted for 32% of the variance in PTSD and 19% of the variance in the adaptation scale. Results were explored in terms of risk and resilience factors.

Maternal Factors as Moderators or Mediators of PTSD Symptoms in Very Young Children: A Two-Year Prospective Study

Research has suggested that parenting behaviors and other parental factors impact the long-term outcome of children's posttraumatic stress disorder (PTSD) symptoms. In a sample of 62 children between the ages of one and six who experienced life-threatening traumas, PTSD was measured prospectively two years apart. Seven maternal factors were measured in a multi-method, multi-informant design. Both moderation and mediation models, with different theoretical and mechanism implications, were tested. Moderation models were not significant. Mediation models were significant when the mediator variable was maternal symptoms of PTSD or depression (measured at Time 1), self-report of maternal escape/avoidance coping (measured at Time 2), or self-report emotional sensitivity (measured at Time 2). Greater maternal emotional sensitivity was associated with greater Time 2 PTSD symptoms among children. Observational measures of emotional sensitivity as the mediator were not supported. Correlation of parents' and children's symptoms is a robust finding, however caution is warranted in attributing children's PTSD symptoms to insensitive parenting.

Mental Disorders in Early Childhood

BACKGROUND

About 17% of all children suffer from a mental disorder in early childhood, defined as the period up to the age of 6 years.

METHODS

This review is based on publications retrieved by a selective search in PubMed and the Web of Science, as well as on the authors' clinical and scientific experience.

RESULTS

In children up to age 2, disorders of emotional and motor regulation are common (ca. 7%), as are feeding problems (25%), which persist in 2% of children to meet the diagnostic criteria for a feeding disorder. Reactive attachment disorder, a serious mental illness, has a prevalence of about 1%: it is more common among children in situations of increased risk, e.g., orphanages and foster homes. Preschool children can develop anxiety disorder and depressive disorder, as well as hyperactivity and behavioral disorders (the latter two mainly in boys). Parent training and parent-child psychotherapy have been found to be effective treatments. There is no evidence that psychotropic drugs are effective in early childhood.

CONCLUSION

The diagnostician should act cautiously when assigning psychopathological significance to symptoms arising in early childhood but should still be able to recognize mental disorders early from the way they are embedded in the child's interactive relationships with parents or significant others, and then to initiate the appropriate treatment. Psychotherapy in this age group is still in need of validation by efficacy studies and longitudinal studies of adequate quality.

Comparing three diagnostic algorithms of posttraumatic stress in young children exposed to accidental trauma: an exploratory study

BACKGROUND

Both the DSM-5 algorithm for posttraumatic stress disorder (PTSD) in children 6 years and younger and Scheeringa's alternative PTSD algorithm (PTSD-AA) aim to be more developmentally sensitive for young children than the DSM-IV PTSD algorithm. However, very few studies compared the three algorithms simultaneously. The current study explores diagnostic outcomes of the three algorithms in young child survivors of accidental trauma.

METHODS

Parents of 98 young children (0-7 years) involved in an accident between 2006 and 2012 participated in a semi-structured telephone interview. Child posttraumatic stress symptoms (PTSS) were measured with the Anxiety Disorders Interview Schedule for DSM-IV-Child Version (ADIS-C/P), complemented with items from the Diagnostic Infant and Preschool Assessment (DIPA). Descriptive statistics were used to analyze the characteristics of the children, accident related information and PTS symptoms. We compared the three PTSD algorithms in order to explore the diagnostic outcomes.

RESULTS

A total of 9 of the children (9.2 %) showed substantial PTSS. Of these children 2 met the criteria of all three algorithms, 7 met both the DSM-5 subtype for children 6 years and younger and the PTSD-AA algorithm, and 2 did not fully meet any of the algorithms (subsyndromal PTSD).

CONCLUSIONS

For young children, the DSM-5 subtype for children 6 years and younger and the PTSD-AA algorithm appear to be better suited than the previous DSM-IV algorithm. It remains important that clinicians pay attention to children with subsyndromal PTSD.

Trauma-focused cognitive behaviour therapy versus treatment as usual for post traumatic stress disorder (PTSD) in young children aged 3 to 8 years: study protocol for a randomised controlled trial

BACKGROUND

Following horrific or life-threatening events approximately 10 to 15% of young children develop post traumatic stress disorder (PTSD). The symptoms of this disorder are distressing - nightmares, flashbacks, anger outbursts and disturbed play. These symptoms cause major disruption to a child's functioning and, if left untreated, can persist for many years. As yet, there are no established empirically-validated treatments for PTSD in young children. Trauma-focused cognitive behaviour therapy (TF-CBT) is a psychological intervention that is effective in treating the disorder in older children (8 to 12 years), adolescents and adults. This study examines TF-CBT adapted for children aged between 3 and 8 years.

METHODS/DESIGN

This protocol describes a two-arm exploratory randomised controlled trial comparing TF-CBT to treatment as usual (TAU) in children aged 3 to 8 years with a principal diagnosis of PTSD following a single-event discrete trauma. Using a half-crossover design, 44 participants will be randomly allocated to receive the intervention or to receive TAU. Those allocated to TAU will be offered TF-CBT at the end of the 'treatment' period (approximately 12 weeks) if still indicated. The primary outcome is PTSD diagnosis according to DSM-5 criteria for children 6 years and younger at post-treatment. Secondary outcomes include effects on co-morbid diagnoses and changes in emotion and trauma symptoms at each of the follow-up points (post-treatment, 3-months, 12-months). Additionally, broader efficacy will be considered with regard to treatment feasibility, acceptability and service utilisation. The key targets of the intervention are trauma memory, the interpretation of the meaning of the event, and the management of symptoms.

DISCUSSION

This is the first European trial to examine the efficacy of TF-CBT in alleviating PTSD in very young children. As well as providing much-needed data on the utility of the intervention, this exploratory trial will also allow us to gather important information about the feasibility of delivering the treatment in UK National Health Service (NHS) settings, and its acceptability to the children and their families. This study will highlight aspects of the intervention that need improvement or modification in preparation for a full-scale evaluation in a larger sample.

Psychological Distress in Chimpanzees Rescued From Laboratories

The United States is one of the last countries allowing invasive research on chimpanzees. Biomedical research on chimpanzees commonly involves maternal deprivation, social isolation, intensive confinement, and repetitive invasive procedures. These physically harmful and psychologically traumatic experiences cause many chimpanzees to develop symptoms of psychopathology that persist even after relocation from laboratories to sanctuaries. Through semistructured interviews with chimpanzee caregivers, direct behavioral observations, and consultation of laboratory records, we were interested in qualitatively analyzing symptoms of psychological distress in a sample of 253 chimpanzees rescued from biomedical research now residing at an accredited chimpanzee sanctuary. We present the results of this analysis and include an illustrative case study of one rescued chimpanzee who engages in self-injurious behaviors and meets modified Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for posttraumatic stress disorder. We discuss our results in light of recent policy changes regarding the use of chimpanzees in biomedical research in the United States and their implications for those involved in the rescue and rehabilitation of chimpanzees from biomedical research.

Psychometric properties of the Turkish version of the child PTSD symptom scale

OBJECTIVE

Psychometric properties of the Turkish version of the Child PTSD Symptom Scale (CPSS) were examined in a sample of young individuals who experienced a severe earthquake.

METHOD

Subjects were 479 children and adolescents recruited from schools after 18 months of Van earthquake. Mean age was 12.83 (SD±1.88), ranging from 8 to 18.

RESULTS

Psychometric features were generally good for the CPSS. The original three-factor structure was replicated in this study. Internal consistency of the scale was good (ranged from α=.70 to α=.89 for total and subscale scores). The CPSS demonstrated good convergent validity with Child Post-Traumatic Stress Disorder Reaction Index scores as well as good divergent validity with the State and Trait Anxiety Inventory for Children and Child Depression Inventory. As an evidence for a good discriminant validity, the CPSS successfully distinguished high PTSD individuals from low PTSD individuals.

CONCLUSION

The CPSS had sound psychometric properties in a Turkish youth population.

Posttraumatic symptom structure across age groups

The applicability of diagnostic criteria of Posttraumatic Stress Disorder to the pediatric population has been a focus of much debate (e.g., Carrion, Weems, Ray, & Reiss, 2002 ), informing changes in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). The current study examined the factor structure of posttraumatic distress among adult versus pediatric samples using confirmatory factor analysis. The analysis was performed on the DSM-IV-adherent Posttraumatic Diagnostic Scale (Foa, Cashman, Jaycox, & Perry, 1997 ) and Child Posttraumatic Symptom Scale (Foa, Johnson, Feeny, & Treadwell, 2001 ). The sample included 378 adult and 204 child and adolescent victims of diverse single-event traumas. A series of models based on previous findings and DSM-IV specification were evaluated. A 4-factor model (Intrusions, Avoidance, Dysphoria, and Hyperarousal), similar to the DSM-5 model, best fit the data among adults, and a different 4-factor model (Intrusion, Avodiance, Numbing, and Hyperarousal) best fit the data among children and adolescents. Despite some similarity, the posttraumatic symptom profiles of pediatric and adult samples may differ. These differences are not fully incorporated into the DSM-5, and warrant further examination.

Psychological therapies for the treatment of post-traumatic stress disorder in children and adolescents (Review)

BACKGROUND

Post-traumatic stress disorder (PTSD) is highly prevalent in children and adolescents who have experienced trauma and has high personal and health costs. Although a wide range of psychological therapies have been used in the treatment of PTSD there are no systematic reviews of these therapies in children and adolescents.

OBJECTIVES

To examine the effectiveness of psychological therapies in treating children and adolescents who have been diagnosed with PTSD.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to December 2011. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: CENTRAL (the Cochrane Central Register of Controlled Trials) (all years), EMBASE (1974 -), MEDLINE (1950 -) and PsycINFO (1967 -). We also checked reference lists of relevant studies and reviews. We applied no date or language restrictions.

SELECTION CRITERIA

All randomised controlled trials of psychological therapies compared to a control, pharmacological therapy or other treatments in children or adolescents exposed to a traumatic event or diagnosed with PTSD.

DATA COLLECTION AND ANALYSIS

Two members of the review group independently extracted data. If differences were identified, they were resolved by consensus, or referral to the review team. We calculated the odds ratio (OR) for binary outcomes, the standardised mean difference (SMD) for continuous outcomes, and 95% confidence intervals (CI) for both, using a fixed-effect model. If heterogeneity was found we used a random-effects model.

MAIN RESULTS

Fourteen studies including 758 participants were included in this review. The types of trauma participants had been exposed to included sexual abuse, civil violence, natural disaster, domestic violence and motor vehicle accidents. Most participants were clients of a trauma-related support service. The psychological therapies used in these studies were cognitive behavioural therapy (CBT), exposure-based, psychodynamic, narrative, supportive counselling, and eye movement desensitisation and reprocessing (EMDR). Most compared a psychological therapy to a control group. No study compared psychological therapies to pharmacological therapies alone or as an adjunct to a psychological therapy. Across all psychological therapies, improvement was significantly better (three studies, n = 80, OR 4.21, 95% CI 1.12 to 15.85) and symptoms of PTSD (seven studies, n = 271, SMD -0.90, 95% CI -1.24 to -0.42), anxiety (three studies, n = 91, SMD -0.57, 95% CI -1.00 to -0.13) and depression (five studies, n = 156, SMD -0.74, 95% CI -1.11 to -0.36) were significantly lower within a month of completing psychological therapy compared to a control group. The psychological therapy for which there was the best evidence of effectiveness was CBT. Improvement was significantly better for up to a year following treatment (up to one month: two studies, n = 49, OR 8.64, 95% CI 2.01 to 37.14; up to one year: one study, n = 25, OR 8.00, 95% CI 1.21 to 52.69). PTSD symptom scores were also significantly lower for up to one year (up to one month: three studies, n = 98, SMD -1.34, 95% CI -1.79 to -0.89; up to one year: one study, n = 36, SMD -0.73, 95% CI -1.44 to -0.01), and depression scores were lower for up to a month (three studies, n = 98, SMD -0.80, 95% CI -1.47 to -0.13) in the CBT group compared to a control. No adverse effects were identified. No study was rated as a high risk for selection or detection bias but a minority were rated as a high risk for attrition, reporting and other bias. Most included studies were rated as an unclear risk for selection, detection and attrition bias.

AUTHORS' CONCLUSIONS

There is evidence for the effectiveness of psychological therapies, particularly CBT, for treating PTSD in children and adolescents for up to a month following treatment. At this stage, there is no clear evidence for the effectiveness of one psychological therapy compared to others. There is also not enough evidence to conclude that children and adolescents with particular types of trauma are more or less likely to respond to psychological therapies than others. The findings of this review are limited by the potential for methodological biases, and the small number and generally small size of identified studies. In addition, there was evidence of substantial heterogeneity in some analyses which could not be explained by subgroup or sensitivity analyses. More evidence is required for the effectiveness of all psychological therapies more than one month after treatment. Much more evidence is needed to demonstrate the relative effectiveness of different psychological therapies or the effectiveness of psychological therapies compared to other treatments. More details are required in future trials in regards to the types of trauma that preceded the diagnosis of PTSD and whether the traumas are single event or ongoing. Future studies should also aim to identify the most valid and reliable measures of PTSD symptoms and ensure that all scores, total and sub-scores, are consistently reported.

The diagnosis of posttraumatic stress disorder in school-aged children and adolescents following pediatric intensive care unit admission

OBJECTIVES

This study explored the diagnosis of posttraumatic stress disorder (PTSD) in children and adolescents following pediatric intensive care unit (PICU) admission. Specifically, the study aimed to describe the presentation and prevalence of PTSD symptoms 6 months postdischarge, explore the validity of the DSM-IV PTSD algorithm and alternative PTSD algorithm (PTSD-AA) in school-aged children and adolescents, and examine the diagnostic utility of Criterion C3 (inability to recall aspects of a trauma) in this cohort.

METHODS

Participants were 59 children aged 6-16, admitted to PICU for at least 8 hours. PTSD was assessed via diagnostic interview (Children's PTSD Inventory) 6 months following PICU discharge.

RESULTS

The PTSD-AA was found to provide the most valid measure of PTSD at 6 months. Removing Criterion C3 improved the validity of Criterion C.

CONCLUSIONS

This study supports the use of the PTSD-AA excluding Criterion C3 for identifying highly traumatized children and adolescents following PICU admission.

Childhood exposure to violence and lifelong health: clinical intervention science and stress-biology research join forces

Many young people who are mistreated by an adult, victimized by bullies, criminally assaulted, or who witness domestic violence react to this violence exposure by developing behavioral, emotional, or learning problems. What is less well known is that adverse experiences like violence exposure can lead to hidden physical alterations inside a child's body, alterations that may have adverse effects on life-long health. We discuss why this is important for the field of developmental psychopathology and for society, and we recommend that stress-biology research and intervention science join forces to tackle the problem. We examine the evidence base in relation to stress-sensitive measures for the body (inflammatory reactions, telomere erosion, epigenetic methylation, and gene expression) and brain (mental disorders, neuroimaging, and neuropsychological testing). We also review promising interventions for families, couples, and children that have been designed to reduce the effects of childhood violence exposure. We invite intervention scientists and stress-biology researchers to collaborate in adding stress-biology measures to randomized clinical trials of interventions intended to reduce effects of violence exposure and other traumas on young people.

Prevalence and trajectory of psychopathology among child and adolescent survivors of disasters: a systematic review of epidemiological studies across 1987-2011

AIMS

The goal of this paper was to systematically review evidence on (1) the potential magnitude of the psychopathological impacts of community-wide disasters on child and adolescent survivors, and (2) the long-term course or trajectory of disaster-induced psychopathology among children and adolescents.

METHODS

The PubMed/MEDLINE and PsycINFO databases were searched from their respective inception through December 2011. All of the resulting epidemiological studies of child and adolescent survivors following community-wide disasters were examined.

RESULTS

Sixty cross-sectional studies and 25 longitudinal or long-term follow-up studies were identified. The estimated rates of posttraumatic stress disorder (PTSD) and depression among child and adolescent survivors varied greatly across the included studies, ranging from 1.0 to 95 % and 1.6 to 81 %, respectively, while the reported rates of diagnosable PTSD according to the DSM-IV criteria and diagnosable depression ranged from 1.0 to 60 % and 1.6 to 33 %, respectively. The long-term courses of psychopathology among youthful survivors were summarized. Methodological issues with those studies were discussed.

CONCLUSIONS

The empirical findings summarized in this review highlight the importance of psychosocial intervention at early postdisaster stages for child and adolescent survivors. The methodological flaws revealed by this review indicate the need for continued attempts to better understand the epidemiology and trajectory of psychopathological problems among youthful survivors.

A school based study of psychological disturbance in children following the Omagh bomb

OBJECTIVE

To assess the extent and nature of psychiatric morbidity among children (aged 8 to 13 years) 15 months after a car bomb explosion in the town of Omagh, Northern Ireland.

METHOD

A survey was conducted of 1945 school children attending 13 schools in the Omagh district. Questionnaires included demographic details, measures of exposure, the Horowitz Impact of Events Scale, the Birleson Self-Rating Depression Scale, and the Spence Children's Anxiety Scale.

RESULTS

Children directly exposed to the bomb reported higher levels of probable PTSD (70%), and psychological distress than those not exposed. Direct exposure was more closely associated with an increase in PTSD symptoms than in general psychiatric distress. Significant predictors of increased IES scores included being male, witnessing people injured and reporting a perceived life threat but when co-morbid anxiety and depression are included as potential predictors anxiety remains the only significant predictor of PTSD scores.

CONCLUSIONS

School-based studies are a potentially valuable means of screening and assessing for PTSD in children after large-scale tragedies. Assessment should consider type of exposure, perceived life threat and other co-morbid anxiety as risk factors for PTSD.

Stress-related changes in toddlers and their mothers following the attack of September 11

Unlike other forms of disaster, terrorism is not confined to a particular place or time, and recent evidence indicates that the 9/11 terrorist attack was a significant macrolevel stressor affecting the health and mental health of United States citizens. No studies, however, have reported symptoms in toddlers and their mothers both before and after the attacks. To address this gap, we examined the effects of the 9/11 terrorist attacks on mothers and their 33-month-old toddlers. The attacks occurred during data collection at 33 months of a longitudinal study. Thirty-three-month-old toddlers and mothers who were assessed after the attacks were compared with those assessed before the attacks. When changes were examined from a previous wave of data collected at 15 months, those in the after-attack group showed poorer health, lower child acceptance, and marginally more anxiety, and their toddlers cried more and slept less, whereas the before-attack group showed no changes. Our findings contribute to research documenting widespread effects of the 9/11 terrorist attack on stress-related symptoms and suggest that greater attention must be placed on the needs of our youngest citizens and their caregivers.
