A meta-analysis of risk factors for post-traumatic stress disorder in children and adolescents

Psychological peritraumatic risk factors for post-traumatic stress disorder in children and adolescents: A meta-analytic review

BACKGROUND

Meta-analytic reviews concerning predictors of PTSD in children and adolescents have predominantly identified evidence relating to pre- and post-trauma risk factors; however, there is little evidence regarding peritraumatic risk factors. This paper comprised a systematic review and meta-analysis of studies exploring psychological peritraumatic risk factors for PTSD in youth.

METHODS

Thirty-two studies were identified. Random effects meta-analyses were undertaken, with meta-regressions to explore the moderating role of study characteristics (gender, sex, timing of assessment after trauma, study quality, design and trauma type) on the size of effect of predictive factors.

RESULTS

Peritraumatic subjective threat (k = 28; r = 0.37, 95% CI=0.31-0.42) yielded a medium effect size estimate, while dissociation (k = 5; r = 0.17, 95% CI=0.03-0.29) and data-driven processing (feeling muddled or confused during the trauma) (k = 2; r = 0.29, 95% CI=0.14-0.43) yielded smaller population effect size estimates for the relationship with PTSD symptoms. Perceived life threat yielded a medium sized effect (k = 12; r = 0.37, 95% CI=0.32-0.41). The relationship between subjective threat and PTSD symptoms was moderated by the percentage of female participants. Estimates of heterogeneity were high in studies assessing perceived threat and fear (I² = 95%), but moderate and low within studies assessing dissociation and data-driven processing (I² = 57% and 0%, respectively).

LIMITATIONS

Peritraumatic psychological processes were commonly assessed using single-item measures. Studies primarily concerned single-incident traumas, limiting generalisability.

CONCLUSIONS

Peritraumatic experiences, particularly relating to subjective threat, are important correlates of subsequent PTSD, which implicates timely assessment of these experiences in youth to inform identification of at-risk groups and implementation and design of intervention.

The Change in Parental Symptoms and Dysfunctional Cognitions in the Course of Trauma-Focused Cognitive-Behavioral Therapy: Sustainability Until One-Year Post-Treatment

Objectives: Symptoms of distress and dysfunctional posttraumatic cognitions (PTCs) have been frequently described in parents of children and adolescents with posttraumatic stress symptoms (PTSS), especially if the parents had experienced traumatic events themselves. The inclusion of non-offending parents in trauma-focused cognitive-behavioral therapy (TF-CBT) for children and adolescents may, thus, help parents to cope with the traumatic experience of their child. The aim of this study is to investigate the effects of TF-CBT on the parents, while taking their own history of traumatic experiences into account. Methods: Parents (N = 57, 84.2% mothers) of children and adolescents who received TF-CBT completed the Posttraumatic Diagnostic Scale, the Beck Depression Inventory, the State-Trait Anxiety Inventory, and the Posttraumatic Cognitions Inventory. Treatment effects and the sustainability at 6- and 12 months post-treatment were tested via repeated-measures analysis of variance, following the intention-to-treat approach. Results:N = 19 (35.2%) of the parents evaluated their child's trauma as the worst event, 18 (33.3%) rated their own experience as their worst event, and 17 (31.5%) indicated that their own worst traumatic experience was the same type as their child's trauma. Significant improvements (p < 0.001) emerged for parental PTSS [F(2, 837) = 8.27; d = 0.30], depression [F(3, 284) = 14.73; d = 0.41], anxiety symptoms [F(3, 185) = 17.44; d = 0.64], and dysfunctional PTCs [F(2, 465) = 13.58; d = 0.46]. Sustainability of these treatment gains remained at both follow-up time points (p < 0.05). There was no interaction between the time and the reference person of the traumatic index event, reported by parents. Conclusion: These results indicate parental benefits from participation in TF-CBT delivered to their child, until 1-year post-treatment and independently from the parental trauma history. The ongoing tendency of improvement might indicate that TF-CBT furnishes children and their parents with skills to further reduce the impact of their traumatic memories.

Child and Family Factors Associated With Posttraumatic Stress Responses Following a Traumatic Medical Event: The Role of Medical Team Support

OBJECTIVES

This study examined the contribution of pretrauma psychosocial factors (child emotional functioning, family resources, family functioning, and social support) and environmental factors (mother's posttraumatic stress symptoms [PTSSs], medical team support [MTS]) to PTSSs of injured or seriously ill children within a pediatric rehabilitation setting. It was hypothesized that psychosocial variables would be strongly associated with child's PTSS; that mother's PTSS and MTS would mediate the association between psychosocial factors and child's PTSS; that mother's report on child's PTSS would mediate the association between mother's PTSS and child's PTSS.

METHODS

Participants were 196 children hospitalized following an injury/illness and assessed M = 47.7 days postevent. Children completed measures of PTSS, mothers completed measures of their own PTSS, child's PTSS, and pretrauma psychosocial factors. Family's therapist completed a MTS measure. Structural equation modeling was employed to evaluate the study hypotheses.

RESULTS

Pretrauma family structure and resources were associated with child's self-reported PTSS; each pretrauma variable and mother's report of child's PTSS was significantly associated. Although mother's PTSS was not directly associated with child's PTSS, this relationship was mediated by mother's report of child's PTSS. MTS mediated the relationship between pretrauma social support and mother's PTSS.

CONCLUSION

This study further explicates the utility of a biopsychosocial framework in predicting childhood PTSS. Findings confirm the role of pretrauma factors and environmental factors at the peritrauma period in the development of PTSS following a pediatric injury/illness. Mother's PTSS and MTS may be appropriate targets for prevention and early intervention.

Coping and support-seeking in out-of-home care: a qualitative study of the views of young people in care in England

OBJECTIVES

Young people who have been removed from their family home and placed in out-of-home care have commonly experienced abuse, neglect and/or other forms of early adversity. High rates of mental health difficulties have been well documented in this group. The aim of this research was to explore the experiences of these young people within the care system, particularly in relation to support-seeking and coping with emotional needs, to better understand feasible and acceptable ways to improve outcomes for these young people.

DESIGN AND STUDY SETTING

This study used 1:1 semistructured qualitative interviews with young people in out-of-home care in England, to provide an in-depth understanding of their views of coping and support for their emotional needs, both in terms of support networks and experiences with mental health services. Participants were 25 young people aged 10-16 years old (56% female), and included young people living with non-biological foster carers, kinship carers and in residential group homes.

RESULTS

Participants described positive (eg, feeling safe) and negative (eg, feeling judged) aspects to being in care. Carers were identified as the primary source of support, with a supportive adult central to coping. Views on support and coping differed for young people who were experiencing more significant mental health difficulties, with this group largely reporting feeling unsupported and many engaging in self-harm. The minority of participants had accessed formal mental health support, and opinions on usefulness were mixed.

CONCLUSIONS

Results provide insight, from the perspective of care-experienced young people, about both barriers and facilitators to help-seeking, as well as avenues for improving support.

The Good Enough Parenting early intervention schema therapy based program: Participant experience

Background and objectives

Schema therapy (ST) has become a mainstream therapy for the treatment of psychopathology and has been validated through a series of large scale, international randomized control trials. Among other things, schema therapy emphasizes the meeting of core emotional needs in children by primary caregivers as these unmet needs continue to adversely affect their lives into adulthood. An early intervention parenting program has been developed to help parents meet these core emotional needs in order to prevent the development of psychopathology in the first place. The program, Good Enough Parenting, is equally focused on reducing problems and strengthening parenting practices, regardless of where the child is on the “disordered to well-being continuum”. This study aims to explore “patient experience” by users of this program. Best clinical research guidelines advocate that participants should be used as collaborators rather than pure recipients; this process should predate large scale trials.

Design

An exploratory qualitative study with 55 parent-participants of Good Enough Parenting was conducted.

Methods

One-to-one interviews were conducted with participants, using critical incident technique and guided by semi-structured interview schedule, to explore their experiences with the program. Transcripts were then analyzed using thematic analysis.

Results

Coding showed a high degree of inter-rater reliability (kappa value of 0.78). The themes that emerged were Cultivating Awareness of Parents’ Own Schemas, Cultivating Intentionality, Working through Developmental Issues, Responses to Challenges at Home, Performing Multiple Roles, and the Learning Process. Participants overwhelmingly reported satisfaction within these key themes.

Conclusions

The results support the development of the program and the choice of “participant reported outcome measures” for use in subsequent randomized controlled trials.

Feasibility and Effectiveness of a New Short-Term Psychotherapy Concept for Adolescents With Emotional Dysregulation

Background: The 'Stress-Trauma-Symptoms-Regulation-Treatment' (START) is an innovative manualized short-term treatment program for stabilization and stress resilience in emotionally dysregulated adolescents, based on an approach of stress and management and emotional regulation. The current pilot trial aims to assess the feasibility and effectiveness of the START intervention program for improvement of emotion regulation. Methods: Sixty-six adolescents between the age of 13-18 years admitted to a psychiatric unit for acute emotional or behavioral dysregulation took part in the START program for 5 weeks in an open group setting with two sessions per week (70 min/session). Before treatment, we assessed a history of adverse experience with the Child and Adolescent Trauma Screen (CATS) and the Child Posttraumatic Cognitions Inventory (CPTCI). Before and after treatment, the participants completed the FEEL-KJ, a self-report screening instrument of emotional regulation and coping strategies. Results: A large proportion of this sample had experienced traumatic events based on the CATS (75%) and the CPTCI (82%). The mean FEEL-KJ score significantly decreased after the intervention (d = -0.248, p = 0.037), while no difference was observed with regard to mean level of adaptive emotion regulation strategies (d = 0.202, p = 0.207). A positive effect of the intervention was observed on three components of the adaptive FEEL-KJ scale: accepting (d = 0.289, p = 0.08), forgetting (d = 0.271, p = 0.049) and dealing with anger (d = 0.309, p = 0.034). Conclusion: START demonstrates preliminary evidence for improvement in emotional dysregulation after a 5-weeks course of treatment. Therefore, this short-term intervention can possibly be regarded as a tool to improve emotional stability in children with a high load of trauma-related psychopathology. The results are promising and warrant future studies, specifically randomized controlled trials on the effectiveness of START for strengthening resilience at-risk-populations.

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

BACKGROUND

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

OBJECTIVE

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

METHOD

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

RESULTS

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

CONCLUSIONS

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

Sex differences in post-traumatic stress disorder in a high adversity cohort of South African adolescents: an examination of depressive symptoms, age, and trauma type as explanatory factors

BACKGROUND

Evidence from high-income countries (HICs) has documented a higher rate of post-traumatic stress disorder (PTSD) in females than males. However, data are limited on sex differences in PTSD from low- and middle-income countries (LMICs), despite particularly high levels of trauma experienced by LMIC youth.

OBJECTIVES

In a sample of adolescents from an impoverished South African community, we examined sex differences in PTSD, as well as co-occurring depression, adolescent age, and the type and extent of trauma exposure as potential contributors to female vulnerability.

METHODS

Participants were recruited from high schools in the Khayelitsha area of Cape Town. Self-reported trauma exposure, PTSD and depressive symptoms were measured in 797 adolescents (62% female) aged 13-17 years. Poisson regressions were used to examine Risk Ratios (RR) based on probable PTSD diagnoses, and linear regressions were applied to assess posttraumatic stress symptom (PTSS) severity.

RESULTS

92% of adolescents reported trauma exposure, of whom 28% had probable PTSD. Prevalence of PTSD was higher for females than for males, even when controlling for total trauma exposure (RR = 1.71, p < .001) and co-occurring depressive symptoms (RR = 1.45, p = .005). By contrast, sex differences in depression were eliminated after controlling for co-occurring PTSS. There was little evidence of age effects on the emergence of sex differences. At lower thresholds of interpersonal trauma, females showed higher levels of PTSS compared to males, but no sex differences were found at high levels of exposure.

CONCLUSION

Higher PTSD rates are observed in adolescent females in a high adversity-LMIC sample suggesting sex differences are robust across international contexts. Sex differences in PTSD are unlikely to be explained by co-occurring depression and in this context sex differences in depression may be secondary to trauma and PTSD. However, exposure to significant interpersonal trauma appears to overrule any specific female vulnerability.

The Relevance of Cognitive Behavioral Models of Post-Traumatic Stress Following Child Maltreatment: A Systematic Review

While it is known that young people exposed to maltreatment or abuse are at elevated risk of developing post-traumatic stress disorder (PTSD), much of our current knowledge of mechanisms that link trauma to childhood PTSD is based on single-incident, often noninterpersonal, trauma. Theoretical models highlight psychological processes of appraisals, memory, and coping as important for the development of PTSD. The aim of this review was to synthesize the literature on the role of these key psychological processes in relation to PTSD in maltreated children and teens. Studies were included if they (1) identified a sample of maltreated individuals, ≤18 years old; (2) measured (a) trauma memory, (b) appraisals, or (c) post-trauma cognitive or behavioral responses; and (3) measured PTSD symptoms. The systematic search of three electronic databases (American Psychological Association PsychNet, PubMed, and Published International Literature on Traumatic Stress) resulted in the inclusion of 36 papers, which described 31 studies and 33 unique samples. The review found cognitive behavioral models of PTSD appeared appropriate for understanding outcomes following maltreatment, but further research is needed on all processes, particularly trauma memory. Overall, there remain significant gaps in our knowledge of how psychological processes link maltreatment to PTSD. There is limited evidence concerning how maltreatment-related characteristics (e.g., chronicity, duration, and type of abuse) influence psychological processes and in turn affect outcomes. This review recommends further research in this area and suggests that, at the very least, comprehensive assessment should be conducted with all young people reporting maltreatment to identify appraisals and coping strategies that will potentially impact on their ongoing adjustment.

Earthquake Exposure and PTSD Symptoms Among Disaster-Exposed Adolescents: A Moderated Mediation Model of Sleep Problems and Resilience

Considerable studies have explored the potential mechanisms between trauma exposure and PTSD, but little is known about the role of sleep problems and resilience in this relationship. To address this research gap, the present study examined whether sleep problems mediated the relationship between earthquake exposure and PTSD symptoms, and whether this mediating process was moderated by resilience. A sample of 1,342 adolescents (M _age = 15.54 years, SD = 1.26) completed questionnaires regarding earthquake exposure, sleep problems, resilience, and PTSD symptoms 12 months after a devastating earthquake in China. After controlling for demographic variables, earthquake exposure was significantly, and positively associated with PTSD symptoms, and sleep problems partially mediated this relationship. Tests of moderated mediation further revealed that resilience moderated the relationship between earthquake exposure and PTSD symptoms as well as sleep problems and PTSD symptoms. Specifically, the relationship between earthquake exposure and PTSD symptoms was only significant for adolescents with a lower level of resilience; meanwhile, the positive relationship between sleep problems and PTSD symptoms was stronger among low-resilient adolescents. Therefore, sleep-targeted and resilience-based interventions may be effective in alleviating PTSD symptoms resulted from the earthquake.

The effect of parental emotional abuse on the severity and treatment of PTSD symptoms in children and adolescents

BACKGROUND

Maltreatment by a primary caregiver is an important risk factor for the development of PTSD symptoms. Whereas meta-analyses indicate that parental emotional abuse is one of the most common forms of maltreatment, the impact of emotional abuse on PTSD symptoms and treatment effectiveness is still unclear, especially in children.

OBJECTIVE

We aimed to investigate the impact of parental emotional abuse on PTSD symptom severity and effectiveness of trauma treatment in children and adolescents.

METHOD

In an outpatient sample (N = 287, mean age = 15.5 years), emotional abuse, index traumatic event, and PTSD symptoms were assessed at baseline. Thereafter, patients received evidence-based treatment for trauma-related symptoms embedded in a broader (systemic) treatment package. In a subsample (n = 130, mean age = 15.3 years) PTSD symptoms were assessed again 6 and 12 months after baseline.

RESULTS

Emotional abuse (rather than any other type of maltreatment) was associated with more severe PTSD symptoms in all symptom clusters. This was independent of whether emotional abuse was reported as index traumatic event or not. Moreover, PTSD symptoms were significantly reduced 6 months after the start of trauma-focused treatment, and emotional abuse was associated with more severe PTSD symptoms over the course of treatment.

CONCLUSIONS

These findings underline the detrimental nature of emotional maltreatment in the context of PTSD symptomatology and treatment effectiveness. This calls for routine assessment of parental emotional abuse in the diagnostic phase, even when this is not the reason of referral.

Multiple Traumas, Maternal Depression, Mother-Child Relationship, Social Support, and Young Children's Behavioral Problems

This study examined whether maternal depression, mother-child relationships, and maternal perceived social support mediate the associations between child's exposure to multiple traumatic events and behavioral problems. We recruited a representative sample of 904 Israeli (Jewish and Arab) mothers and their 2- to 6-year-old children. Data collection was conducted through structured face-to-face interviews with the mothers between July and November 2011. All measures were completed by the mothers. We used the child's and mother's exposure to political violence questionnaires, Child Behavior Checklist (CBCL), a short version of the Parental Acceptance-Rejection Questionnaire (PARQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Medical Outcomes Study (MOS) Social Support Survey. The research study model was tested using path analysis. The model showed a very good fit to the data, suggesting that maternal rejection, maternal depression, and social support play an important role in child's behavioral problems in the context of multiple traumatic events. Higher levels of maternal rejection were significantly associated with greater children behavior problems. Maternal rejection mediated the associations between maternal depressive symptoms and child's behavioral problems. Maternal perceived social support mediated the associations between child's exposure to multiple traumatic events and child's behavioral problems; child's exposure to multiple traumatic events was associated with lower levels of maternal perceived social support. In turn, lower levels of perceived social support were associated with higher levels of behavioral problems. In conclusion, in accordance with the "social stress framework," social support has a mediation role in the association between exposure to traumatic events and child's behavioral problems. Thus, enhancing social support to mothers to young children in the context of multiple traumatic events is essential for children resiliency.

A longitudinal study of cognitive predictors of (complex) post-traumatic stress in young people in out-of-home care

BACKGROUND

Young people in out-of-home care are substantially more likely to meet criteria for PTSD than their peers, while their early maltreatment exposure may also place them at greater risk of developing the newly proposed complex PTSD. Yet, there remains limited empirical evidence for the mechanisms that might drive either PTSD or complex features in this group, and ongoing debate about the suitability of existing cognitive behavioural models and their related NICE-recommended treatments. In a prospective study of young people in out-of-home care, we sought to identify demographic and cognitive processes that may contribute to the maintenance of both PTSD symptom and complex features.

METHODS

We assessed 120 10- to 18-year-olds in out-of-home care and their primary carer at two assessments: an initial assessment and 12-month follow-up. Participants completed questionnaires on trauma history, PTSD symptoms and complex features, while young people only also self-reported on trauma-related (a) maladaptive appraisals, (b) memory quality and (c) coping. Social workers reported on maltreatment severity.

RESULTS

Young people's maltreatment severity was not a robust predictor of either PTSD symptoms or complex features. All three cognitive processes were moderately-to-strongly correlated with baseline and 12-month PTSD symptoms and complex features, with maladaptive appraisals the most robust unique driver of both, even when controlling for initial PTSD symptom severity.

CONCLUSIONS

Existing cognitive models of PTSD are applicable in this more complex sample of young people. The model was also found to be applicable to the additional features of complex PTSD, with the same processes driving both outcomes at both time points. Clinical implications are discussed.

Posttraumatic stress disorder symptoms in healthcare workers after the peak of the COVID-19 outbreak: A survey of a large tertiary care hospital in Wuhan

This study examined the prevalence of posttraumatic stress disorder (PTSD) symptoms and assessed mental illness via an online survey among healthcare workers (HCWs) at the Central Hospital of Wuhan after the peak of the COVID-19 outbreak. PTSD symptoms were measured using the PTSD Checklist Civilian Version (PCL-C), with a cutoff score of 50. Among the 642 HCWs, the prevalence of probable PTSD was 20.87%. Additionally, 88.88%, 82.09%, 100%, and 95.52% of HCWs with probable PTSD reported varying degrees of anxiety, depression, somatic symptoms, and insomnia, respectively. HCWs with probable PTSD scored higher on the Hospital Anxiety and Depression Scale (HADS), Patient Health questionnaire-15 (PHQ-15), and Insomnia Severity Index (ISI) than non-PTSD HCWs (all p < 0.05). Multivariate regression analysis revealed that HCWs with negative COVID-19 tests (OR, 0.35; 95% CI, 0.21-0.58; p < 0.00), those with high Social Support Self-Rating Scale (SSRS) scores (OR, 0.30; 95% CI, 0.17-0.52; p < 0.00), and HCWs whose family members tested negative (OR, 0.64; 95% CI, 0.42-0.96; p = 0.03) were less likely to have probable PTSD. This study found a high prevalence of probable PTSD and severe mental illness among local HCWs. Our finding emphasizes the need to provide mental health support for HCWs.

Dyadic Profiles of Posttraumatic Stress Symptoms in Mothers and Children Experiencing Intimate Partner Violence

Children who witness intimate partner violence (IPV) develop posttraumatic stress disorder at alarmingly high rates. Research suggests that caregivers' symptoms of posttraumatic stress (PTSS) often co-occur alongside children's PTSS, a phenomenon termed "relational posttraumatic stress." The goal of this study is to use dyad-centered analyses to examine heterogeneity in relational PTSS presentations in mother-child dyads, and to determine factors differentiating relational PTSS profiles. Data were drawn from a sample of 231 IPV-exposed, ethno-racially diverse mother-child dyads, with children ranging from ages 4 to 12. The results of a latent profile analysis indicated that a two-profile model was the best fit with the data. Both profiles indicated similar levels of PTSS across the dyad; however, they differed in overall symptom severity. Parenting and IPV severity significantly predicted profile membership; however, age did not. Results suggest that similarities in PTSS presentation should be expected in mother-child dyads, at least in families who experience IPV.

Early Pain and Other Somatic Symptoms Predict Posttraumatic Stress Reactions in Survivors of Terrorist Attacks: The Longitudinal Utøya Cohort Study

Survivors of traumatic events commonly suffer from long-term pain and related somatic symptomatology. To test the predominant hypothesis that survivors' pain comprises sequela of persistent posttraumatic stress symptoms (PTSS), we assessed the sequential order of symptom development among young survivors of a terrorist attack. All 490 survivors of the 2011 Utøya (Norway) attacks were invited to the longitudinal Utøya cohort study; 355 (72.4%) participated. The mean survivor age was 19.3 years (SD = 4.6) and 169 were female (47.6%). Somatic symptoms, including headache, other pain and fatigue, and PTSS, were measured 4-5 months (T1), 14-16 months (T2), and 32-33 months (T3) after the attack. Longitudinal associations between somatic symptoms and PTSS were assessed in cross-lagged structural equation model (SEM) analyses, which were adjusted for known confounders. Higher pain levels and other somatic symptoms at T1 consistently predicted PTSS at T2 in SEM analyses, r = .473, p < .001. Beyond this early-to-intermediate posttraumatic phase, somatic symptoms did not significantly predict PTSS: T2-T3, r = .024, p = .831; T1-T3, r = -.074, p = .586. PTSS did not significantly predict later somatic symptomatology at T1-T2, r = .093, p = .455; T2-T3, r = .272, p = .234; or T1-T3, r = -.279, p = .077. The findings indicate that survivors' early pain and related somatic symptoms strongly and consistently predict later psychopathology. After severe psychological trauma, early interventions may need to address individuals' pain to hinder chronification.

Prospective prediction of PTSD diagnosis in a nationally representative sample using machine learning

BACKGROUND

Recent research has identified a number of pre-traumatic, peri-traumatic and post-traumatic psychological and ecological factors that put an individual at increased risk for developing PTSD following a life-threatening event. While these factors have been found to be associated with PTSD in univariate analyses, the complex interactions of these risk factors and how they contribute to individual trajectories of the illness are not yet well understood. In this study, we examine the impact of prior trauma, psychopathology, sociodemographic characteristics, community and environmental information, on PTSD onset in a nationally representative sample of adults in the United States, using machine learning methods to establish the relative contributions of each variable.

METHODS

Individual risk factors identified in Waves 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were combined with community-level data for the years concurrent to the NESARC Wave 1 (n = 43,093) and 2 (n = 34,653) surveys. Machine learning feature selection and classification analyses were used at the national level to create models using individual- and community-level variables that would best predict the new onset of PTSD at Wave 2.

RESULTS

Our classification algorithms yielded 89.7 to 95.6% accuracy for predicting new onset of PTSD at Wave 2. A prior diagnosis of DSM-IV-TR Borderline Personality Disorder, Major Depressive Disorder or Anxiety Disorder conferred the greatest relative influence in new diagnosis of PTSD. Distal risk factors such as prior psychiatric diagnosis accounted for significantly greater relative risk than proximal factors (such as adverse event exposure).

CONCLUSIONS

Our findings show that a machine learning classification approach can successfully integrate large numbers of known risk factors for PTSD into stronger models that account for high-dimensional interactions and collinearity between variables. We discuss the implications of these findings as pertaining to the targeted mobilization emergency mental health resources. These findings also inform the creation of a more comprehensive risk assessment profile to the likelihood of developing PTSD following an extremely adverse event.

Stress, Resilience, and Well-Being in Italian Children and Their Parents during the COVID-19 Pandemic

The novel coronavirus (COVID-19) outbreak has forced parents and children to adopt significant changes in their daily routine, which has been a big challenge for families, with important implications for family stress. In this study, we aimed to analyze the potential risk and protective factors for parents' and children's well-being during a potentially traumatic event such as the COVID-19 quarantine. Specifically, we investigated parents' and children's well-being, parental stress, and children's resilience. The study involved 463 Italian parents of children aged 5-17. All participants completed an online survey consisting of the Psychological General Well Being Index (PGWB) to assess parental well-being, the Strengths and Difficulties Questionnaire (SDQ) to measure children's well-being, the Parent Stress Scale (PSS) to investigate parental stress, and the Child and Youth Resilience Measure (CYRM-R) to measure children's resilience. The results show that confinement measures and changes in daily routine negatively affect parents' psychological dimensions, thus exposing children to a significant risk for their well-being. Our results also detect some risk factors for psychological maladjustments, such as parental stress, lower levels of resilience in children, changes in working conditions, and parental psychological, physical, or genetic problems. In this study, we attempted to identify the personal and contextual variables involved in the psychological adjustment to the COVID-19 quarantine to identify families at risk for maladjustment and pave the way for ad hoc intervention programs intended to support them. Our data show promising results for the early detection of the determinants of families' psychological health. It is important to focus attention on the needs of families and children-including their mental health-to mitigate the health and economic implications of the COVID-19 pandemic.

Polyvictimization and Psychological Distress in Early Adolescence: A Mediation Model of Defense Mechanisms and Coping Styles

In the current study, we aim to examine the link between exposure to multiple traumatic events (polyvictimization), posttraumatic stress disorder (PTSD) symptoms (PTSS), and psychiatric symptomatology in early adolescence. Furthermore, we aim to explore the mediating roles of defense styles and coping styles in the associations between polyvictimization, PTSS, and psychiatric symptomatology. Data from a Danish national representative sample of 390 eighth-grade students with a mean age of 13.95 (SD = 0.37) years were used. Participants responded to validated self-report questionnaires in 2001. The dimensions of immature defense styles and emotional and avoidance coping mediated the positive associations between polyvictimization, PTSS, and psychiatric symptomatology. Serial multiple mediation indicated that the sum of exposure to traumatic events was significantly associated with more immature defense styles, associated with both high levels emotional and avoidance coping, which, in turn, were associated with high levels of PTSS and psychiatric symptomatology. Polyvictimization is related to adverse outcomes in early adolescence. Both immature defense styles and emotional and avoidance coping styles should be considered as risk factors for the development of psychological distress following exposure to multiple traumas.

Impact of disaster exposure severity: Cascading effects across parental distress, adolescent PTSD symptoms, as well as parent-child conflict and communication

RATIONALE

Natural disasters are common and have potentially deleterious impacts on individuals, as well as on the relationships among family members (Adams et al., 2015; Paul, 2015). Additionally, caregiver-, offspring-, and family-level outcomes are often correlated following disaster.

OBJECTIVE

Thus, longitudinal work is needed to clarify the prospective associations among such constructs following severe disasters.

METHOD

The current study included 1,271 adolescents and investigated whether disaster exposure impacted adolescent posttraumatic stress disorder (PTSD) symptoms, parent distress, and family parent-child conflict and communication, as well as whether/how these factors influenced one another over time. This study used a dynamic cascade model and included adolescents (ages 12-17) and caregivers present for tornadoes in Missouri and Alabama in 2011. These participants were part of a larger study involving a web-based intervention.

RESULTS

Over and above covariates (i.e., adolescent age, gender, race, treatment, prior trauma, adolescent alcohol use and depressive symptoms, and household income), families who experienced greater severity of disaster exposure had adolescents who reported more baseline PTSD symptoms and caregivers who reported more distress at baseline.

CONCLUSIONS

Providing tangible resources (e.g., housing, food, transportation, essential possessions) to families post-disaster may reduce parent distress and adolescent PTSD symptoms. Additionally, reducing adolescent PTSD symptoms may prospectively improve relationships between parents and adolescents.

Posttraumatic Stress in Children After Injury: The Role of Acute Pain and Opioid Medication Use

OBJECTIVES

After injury, many children experience posttraumatic stress symptoms (PTSS) that negatively impact recovery. Acute pain and PTSS share neurobiological pathways, and acute dosage of morphine has been linked to reduced PTSS in naturalistic studies. However, the complex interactions between pain, morphine and other opioid use, and PTSS have yet to be investigated in robust pediatric samples.This prospective, longitudinal study examined relationships between acute pain, opioid medications, and PTSS after pediatric injury.

METHODS

Ninety-six children aged 8 to 13 years (mean = 10.60, SD = 1.71), hospitalized for unintentional injury, completed assessments at baseline (T1) and 12 weeks (T2) later. Pain ratings and opioid administration data were obtained via chart review.

RESULTS

Structural equation modeling revealed that worst pain endorsed during hospitalization was positively associated with concurrent and later PTSS when controlling for evidence-based risk factors (ie, age, sex, prior trauma history, traumatic appraisals of injury event, heart rate). Neither opioid medications overall nor morphine specifically (milligram/kilogram/day) administered during hospitalization mediated the relationship between pain and T2 PTSS.

CONCLUSIONS

Pain during hospitalization may increase susceptibility for persistent PTSS above and beyond the influence of other empirical risk factors. Findings suggest that pain assessment may be a useful addition to pediatric PTSS screening tools and highlight the need for additional research on pharmacological secondary prevention approaches. Given that inadequate pain control and persistent PTSS each hinder recovery and long-term functioning, better understanding of interactions between acute pain and PTSS after injury is essential for improving screening, prevention, and early intervention efforts.

Does pre-event lack of emotional support increase the risk of post-event PTSD, anxiety, depression symptoms and lack of support? A comparative population-based study among victims of threat and violence

Our knowledge about the effects of perceived emotional support on PTSD, anxiety and depressive symptoms after serious threat and violence is primarily based on post-event studies. Very little is known about the extent to which (1) victims lacking pre-event emotional support are more at risk of post-event symptoms and lack of post-event support than victims with pre-event emotional support, and (2) victims with pre-event emotional support and victims lacking emotional support are more at risk of post-event anxiety and depressive symptoms than nonvictims with similar pre-event support levels. For this purpose, we conducted a 2-wave prospective study (VICTIMS) using the Dutch population-based longitudinal LISS panel. Multivariate logistic regression analyses were conducted, controlling for pre-event demographics, symptoms, and physical, work-related and financial problems. As hypothesized, victims (N^{victims total} = 187) lacking pre-event support more often had high post-event PTSD, anxiety and depressive symptoms than victims with pre-event support. No significant differences were found between victims and nonvictims with pre-event emotional support (N^{nonvictims total} = 2,828, not exposed to any event). Since victims and nonvictims with pre-event support did not differ in post-event symptoms and support, the findings offer strong evidence for the buffering hypothesis of emotional support.

Differential promoter methylation and G-712A polymorphism of brain-derived neurotrophic factor in post-traumatic stress disorder patients of Li and Han populations in Hainan province

This study aimed to explore the correlations of promoter methylation and single-nucleotide polymorphism (SNP) of brain-derived neurotrophic factor (BDNF) with post-traumatic stress disorder (PTSD) in Li and Han nationalities in Hainan province. Depression- and anxiety-related questionnaires were performed for PTSD-related information collection and analysis, with 164 PTSD patients and 141 healthy controls included. Serum BDNF level was measured and the methylation of BDNF promoter was evaluated. The BDNF SNP genotyping was performed, after which the risk genotypes for PTSD were detected and analyzed using logistic regression analysis. Our study found that the PTSD incidence was different in Li and Han nationalities. Serum BDNF level in PTSD patients in Li nationality was obviously lower than that in patients in Han nationality, while the methylation of BDNF promoter was higher in patients in Li nationality. The G-712A rather than rs6265 genotypes presented significant difference between PTSD patients and healthy controls. Meanwhile, the patients in Li nationality with AG genotype at G-712A inclined to depression, and patients with GG genotype had a greater degree of PTSD. G-712A and promoter methylation of BDNF were independent risk factors for PTSD. Our study demonstrated that the differences of PTSD patients between Li and Han nationalities were attributed by SNP G-712A genotypes and promoter methylation of BDNF.

The role of trauma experiences, personality traits, and genotype in maintaining posttraumatic stress disorder symptoms among child survivors of the Wenchuan earthquake

BACKGROUND

Posttraumatic stress disorder (PTSD) is the most prevalent type of psychiatric disorder among children after an earthquake. This study investigated the role of trauma experiences, personality traits, and genotype in the maintenance of PTSD symptoms.

METHODS

In a previous large-scale epidemiological investigation 1 year after the Wenchuan earthquake, 215 children with PTSD symptoms were selected at random with their blood samples collected. All of them were followed up, and their PTSD symptoms were assessed 3 years later. The adolescent version of the UCLA PTSD Reaction Index, the earthquake exposure scale, and the Junior Eysenck Personality Questionnaire were used to determine PTSD symptoms, trauma experiences, and personality traits, respectively. We sequenced candidate genes involved in the regulation of long-term potentiation via NMDA-type receptors to identify the related SNP variations.

RESULTS

Being trapped for a longer period of time, feeling one's own or a family member's life to be in danger, losing a close family member or friend, extraversion, neuroticism, TrkB, G72 and CNTF were found to be associated with the maintenance of PTSD symptoms.

CONCLUSIONS

Experiences, personality traits, and genotype influenced the maintenance of PTSD in child survivors who were considered to be followed up without medicine. This result could help to identify potential targets for treatment and promote the rational allocation of medical resources.

Latent profiles of the comorbidity of the symptoms for posttraumatic stress disorder and generalized anxiety disorder among children and adolescents who are susceptible to COVID-19

The present study aims to examine the comorbidity patterns of the symptoms (intrusion and avoidance) for posttraumatic stress disorder (PTSD) and generalized anxiety disorder (GAD) and the role of perceived threat and courtesy stigma in distinguishing specific patterns of the symptoms for PTSD and GAD among children and adolescents who are susceptible to coronavirus disease 2019 (COVID-19) in Hubei, China. A total of 1172 (683 female and 489 male) children and adolescents aged 8-18 years were involved in completing the measurements of PTSD, GAD, perceived threat of COVID-19, and COVID-19-related courtesy stigma. The Latent Profile Analysis identified the three profiles of the symptoms for PTSD and GAD which were labeled as Moderate PTSD, Mild Comorbidity, and Severe Comorbidity. The scores of the symptoms for PTSD, GAD, perceived threat, and stigma were different among the three profiles. The risk factors (i.e., perceived threat and stigma) that are related to comorbidity patterns were examined through a three-step method. The possibility of entry into the Severe Comorbidity Profile increased with increasing perceived threat and stigma. The mental health care interventions for children and adolescents who are susceptible to COVID-19 can be developed to reduce perceived threat and stigma.

Perceived social support and posttraumatic stress symptoms in children and youth in therapy: A parallel process latent growth curve model

Many studies show that perceived social support protects against the development of posttraumatic stress symptoms (PTSS) in the aftermath of trauma, but less is known about support in relation to PTSS in trauma therapy. This study examined associations between perceived social support and PTSS in children and adolescents during trauma therapy. Parallel process latent growth curve modeling was used to examine trajectories of perceived social support and PTSS over five measurement waves in a sample of 156 patients, aged between 10 and 18 years (M age = 15.1, SD = 2.2, 79.5% girls), randomized to receive trauma-focused cognitive behavior therapy (TF-CBT) or therapy-as-usual (TAU). Across all participants there was an average decline in PTSS and increase of perceived social support from pre-therapy to 18 months after therapy. Most of the change occurred during therapy and was maintained after therapy. Higher levels of PTSS prior to therapy were associated with lower levels of perceived social support prior to therapy, and a decrease in PTSS was associated with increase in perceived social support. This co-development may have been directed by a third underlying factor or short-term temporal effects. Studies investigating within-person associations over shorter time intervals will benefit our understanding of possible temporal effects.

Does the therapist matter? Therapist characteristics and their relation to outcome in trauma-focused cognitive behavioral therapy for children and adolescents

BACKGROUND

There is a broad evidence-base for the effectiveness of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) in treating children and adolescents with posttraumatic stress disorder (PTSD). The effect of therapist characteristics on patient symptoms has been neglected in psychotraumatology research and necessitates further investigation.

OBJECTIVE

This study aims to investigate the impact of therapist characteristics (gender, clinical experience and theoretical background) on posttraumatic stress symptoms (PTSS) in a heterogeneous and international sample of traumatized children and adolescents.

METHOD

Data from two RCTs on the effectiveness of TF-CBT in Norway and Germany were included, comprising N = 52 therapists (78.8% female) and N = 153 patients (72.3% female). All therapists underwent thorough training and continuous supervision in TF-CBT. The Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA) assessed pre- and post-treatment served as the outcome variable in a linear mixed-effects model with therapists' theoretical background, prior clinical experience and gender as independent variables, adjusted for patient gender, measurement time and country. The possibility of an interaction between therapist and patient gender was investigated subsequently.

RESULTS

None of the therapist characteristics were significantly related to PTSS. There was no indication of an interaction between patient and therapist gender (p =.878).

CONCLUSION

The lack of evidence for a relationship of therapists' theoretical orientation and clinical experience with outcome suggests that a wider dissemination of TF-CBT may be warranted. More studies with larger therapist and patient sample sizes and including only community practice are needed.

Traumas and Their Consequences According to Control-Mastery Theory

The aim of this article is to introduce the reader to how control-mastery theory (CMT; Gazzillo, 2016; Silberschatz, 2005; Weiss, 1993), an integrative relational cognitive-dynamic theory of mental functioning, psychopathology, and psychotherapeutic process, understands traumas, their consequences, and their mastery. In the first part of this article, we will present an overview of the debate about the definition of trauma within the different editions of the Diagnostic and Statistical Manual of Mental Disorders. Then, we will focus on the concept of complex traumas and on their consequences on mental health. Finally, we will discuss how CMT conceptualizes traumas and their pathological consequences. We will stress in particular how, according to CMT, in order for a painful experience to become a trauma, its victim has to come to believe that s/he caused it in the attempt to pursue a healthy and adaptive goal. In order to master traumas and disprove the pathogenic beliefs developed from them, people attempt to reexperience situations similar to the traumatic ones in safer conditions while giving them happier endings.

Adverse childhood experiences research: commonalities with similar, arguably identical, literatures and the need for integration

Adverse childhood experiences (ACEs) and their impact cannot be clearly distinguished from other distressing life experiences. Much can be therefore be learned by integrating ACEs research with similar, well-established literatures. Future research needs to explain individual differences in relationships between ACEs and particular variables and locate reliable and strong risk factors for ACEs themselves.

The emergence of sex differences in PTSD symptoms across development: evidence from the ALSPAC cohort

BACKGROUND

Cross-sectional evidence suggests females in late adolescence exhibit higher rates of post-traumatic stress symptoms (PTSS) than males and younger age groups. However, longitudinal evidence is limited, and underlying factors are not well understood. We investigated the emergence of sex differences in PTSS from childhood to adolescence in a large, longitudinal UK cohort, and tested whether these could be explained by overlap between PTSS and depressive symptoms, or onset of puberty.

METHODS

Trauma exposure and PTSS were assessed at ages 8, 10, 13 (parent-report) and 15 (self-report) years in a sub-sample of 9966 children and adolescents from the ALSPAC cohort-study. Analyses of PTSS focused on those who reported potential trauma-exposure at each time-point (ranged from n = 654 at 15 years to n = 1231 at 10 years). Age at peak-height velocity (APHV) was used as an indicator of pubertal timing.

RESULTS

There was no evidence of sex differences in PTSS at ages 8 and 10, but females were more likely to show PTSS at ages 13 (OR 1.54, p = 0.002) and 15 (OR 2.04, p = .001), even once symptoms related to depression were excluded. We found little evidence that the emergence of sex differences was related to pubertal timing (as indexed by APHV).

CONCLUSIONS

Results indicate that females show higher levels of PTSS in adolescence but not during childhood. The emergence of this sex difference does not seem to be explained by overlap with depressive symptoms, while the influence of pubertal status requires further investigation.

Disasters in Germany and France: An Analysis of the Emergency Events Database From a Pediatric Perspective

OBJECTIVE

The objective of this study was to conduct comprehensive analyses of disaster patterns for Germany and France from a pediatric perspective.

METHODS

An analysis of the Emergency Events Database (EM-DAT), epidemiological database with standard methods of descriptive and comparative statistics respecting the strengthening the reporting of observational studies in epidemiology (STROBE) criteria, was performed.

RESULTS

Between 2006 and 2016, there were 41 and 42 disasters in Germany and France claiming 259 and 4973 lives, respectively. Ages of afflicted individuals were not specified in EM-DAT. In Germany, most events were storms (37%), extreme temperatures (17%), floods (17%), and transport accidents (17%). In France, most events were storms (45%), extreme temperatures (17%), floods (19%), and transport accidents (14%). In Germany, most lives (96) were lost in transport accidents. In France, most casualties were due to the heat waves of 2006 and 2015 (1388 and 3275). Reported event types in Germany and France were similar, but heat waves struck France more significantly than Germany.

CONCLUSIONS

Pediatric data are not explicitly captured in EM-DAT, but reported disaster patterns suggest that exposures to heat and cold, storms, trauma, chemicals, water, and infectious agents are possible mechanisms of injury. Age-stratified disaster data are needed to enable a timely, transparent, coordinated, and sustained data-driven approach to pediatric disaster resilience.

Social support modulates the association between PTSD diagnosis and medial frontal volume in Chinese adults who lost their only child

Losing an only child is a devastating life event that a parent can experience and may lead to post-traumatic stress disorder (PTSD). Social support could buffer against the negative influence of this trauma, but the neural mechanism underlying this alleviation effect remains poorly understood. In this study, voxel-based morphometry was conducted on brain MRI of 220 Han Chinese adults who had lost their only child. We performed multiple regression analysis to investigate the associations between social support scores – along with PTSD diagnosis, age, sex, body mass index (BMI) – and brain grey matter (GM) volumes in these bereaved parents. For all trauma-exposed adults, social support-by-diagnosis interaction was significantly associated with medial prefrontal volume (multiple comparisons corrected P ˂ 0.05), where positive correlation was found in adults with PTSD but not in those without PTSD. Besides, PTSD diagnosis was associated with decreased GM volume in medial and middle frontal gyri (P ˂ 0.001, uncorrected); older age was associated with widespread GM volume deficits; male sex was associated with lower GM volume in rolandic operculum, insular, postcentral gyrus (corrected P ˂ 0.05), and lower GM in thalamus but greater GM in parahippocampus (P ˂ 0.001, uncorrected); higher BMI was associated with GM deficits in occipital gyrus (corrected P ˂ 0.05) and precuneus (P ˂ 0.001, uncorrected). In conclusions, social support modulates the association between PTSD diagnosis and medial frontal volume, which may play an important role in the emotional disturbance in PTSD development in adults who lost their only child.

Depicting the associations between different forms of psychopathology in trauma-exposed adolescents

Psychiatric comorbidity in traumatized youth is prevalent, but such associations between two disorders may be confounded with other comorbid conditions. Few studies have examined the unique relationships among multiple disorders. Which disorders maximally explain the relationships between others and whether such disorders differ by sex remain largely unknown. Using a construct-level network approach, this study characterized the independent associations among nine prevalent emotional and behavioral disorders/problems evaluated by the PTSD Checklist for DSM-5, the Revised Children's Anxiety and Depression Scale, and the Youth Self-Report in a sample of 1181 disaster-exposed adolescents (53.9% girls; a mean age of 14.3 ± 0.8 years). The associations were strong among the seven internalizing problems and between the two externalizing ones, but weaker between these two spectra of psychopathology. Major depressive disorder (MDD) was most strongly connected with others, maximally accounting for the associations, especially those between the two spectra. Overall and individual association strength and the connecting role of MDD were generally equivalent across sex. These findings highlight the necessity of MDD in linking comorbid forms of psychopathology in traumatized youth, and suggest MDD as a potential intervention priority in this population.

Posttraumatic Stress Disorder and Childhood Traumatic Loss: A Secondary Analysis of Symptom Severity and Treatment Outcome

Loss is a commonly experienced traumatic event among children. Although the experience of loss can potentially lead to posttraumatic stress symptoms (PTSS), little is known about PTSS levels after traumatic loss versus other traumatic events. We investigated data from a randomized controlled trial (RCT) on trauma-focused cognitive behavioral therapy (TF-CBT) versus a waitlist condition for children with PTSS. In a secondary analysis, we compared participants who reported traumatic loss as their index event (n = 23) to those who reported the two most frequently reported index events in the RCT: sexual abuse (SA; n = 59) and physical violence (PV; n = 55). The index event was rated according to the participants' most distressing traumatic event reported on the Clinician-Administered PTSD Scale for Children and Adolescents. Participants who experienced traumatic loss reported fewer PTSS and better general functioning than those who reported SA. A subgroup RCT (n = 19) revealed TF-CBT to be highly effective in reducing PTSS in cases of traumatic loss, d = 1.69. The effect sizes for PTSS indicated that all three trauma groups benefited from TF-CBT. In the waitlist group, PTSS symptoms improved for SA and PV, ds = 0.76 and 0.98, respectively, but not for traumatic loss, d = 0.23. These findings suggest that TF-CBT is a feasible and promising treatment for children who experience PTSS after traumatic loss. The results are limited by the post hoc quality of the analyses and lack of a measure of grief in the RCT.

Exploring the stress sensitization theory with temperamentally inhibited children: a population-based study

Background

This study explored whether temperamentally inhibited children who experience early trauma are vulnerable to developing internalizing problems in the face of later life-stressors.

Methods

A validated screen for temperamental inhibition was distributed to parents of young children attending preschools in six government regions of Melbourne, Australia. Screening identified 11% of children as inhibited (703 of 6347 screened) and eligible for a prevention study. Participants were 545 parents of inhibited preschoolers (78% uptake), of whom 84% were followed into mid childhood (age 7–10 years: wave 1, n = 446; wave 2, n = 427; wave 3, n = 426). Parents and children then completed questionnaires for child internalizing (anxious and depressive) symptoms, and parents received a diagnostic interview for child anxiety disorder. In mid-childhood parents also completed questionnaires annually to describe recent life-stressors experienced by their child, and any potentially traumatic events in the first four years of life.

Results

Only one in 14 temperamentally inhibited children had experienced a potentially traumatic event in early childhood. In mid childhood 56% experienced recent life-stressors. Inhibited children who had early life trauma experienced slightly more anxiety disorder and symptoms in mid childhood. Those children with more recent life-stressors in mid childhood also had slightly more symptoms of anxiety and depression. In contrast to stress sensitization, inhibited children with early trauma plus recent stressors did not show especially high mid-childhood internalizing difficulties.

Conclusions

Early life trauma and recent life-stressors each convey a small risk for children with an inhibited temperament to develop internalizing problems. Nevertheless, early life stress may not always result in negative sensitization for children in the general population.

Does Maternal Support Mediate or Moderate the Relationship between Sexual Abuse Severity and Children's PTSD Symptoms?

Maternal support and abuse severity are often considered to be vital factors in predicting children's functioning following childhood sexual abuse (CSA); however, much of the prior research has examined support and abuse severity as main effects, without consideration of how these factors may interrelate to predict children's post-CSA functioning. Further, even though mediators and moderators are conceptually distinct, maternal support has been theorized to be both a mediator and a moderator of symptoms, and it is unclear if support acts as either among sexually abused children. The aim of the present study was to investigate whether caregiver-reported maternal support mediates or moderates the relationships between sexual abuse severity and children's trauma-related symptoms. The study included 235 treatment-seeking children ages 3-16 (M = 8.85, SD = 3.77) and their non-offending mothers. Contrary to expectations, caregiver-rated maternal support did not mediate nor moderate the relationship between abuse severity and children's symptoms (range r² =.002 -.03). Caregiver-rated maternal support may play a small role in mitigating sexually abused children's trauma symptoms. Irrespective of abuse severity, children with less supportive mothers may not be at heightened risk for experiencing higher levels of trauma-related difficulties.

Mechanisms linking childhood trauma exposure and psychopathology: a transdiagnostic model of risk and resilience

BACKGROUND

Transdiagnostic processes confer risk for multiple types of psychopathology and explain the co-occurrence of different disorders. For this reason, transdiagnostic processes provide ideal targets for early intervention and treatment. Childhood trauma exposure is associated with elevated risk for virtually all commonly occurring forms of psychopathology. We articulate a transdiagnostic model of the developmental mechanisms that explain the strong links between childhood trauma and psychopathology as well as protective factors that promote resilience against multiple forms of psychopathology.

MAIN BODY

We present a model of transdiagnostic mechanisms spanning three broad domains: social information processing, emotional processing, and accelerated biological aging. Changes in social information processing that prioritize threat-related information-such as heightened perceptual sensitivity to threat, misclassification of negative and neutral emotions as anger, and attention biases towards threat-related cues-have been consistently observed in children who have experienced trauma. Patterns of emotional processing common in children exposed to trauma include elevated emotional reactivity to threat-related stimuli, low emotional awareness, and difficulties with emotional learning and emotion regulation. More recently, a pattern of accelerated aging across multiple biological metrics, including pubertal development and cellular aging, has been found in trauma-exposed children. Although these changes in social information processing, emotional responding, and the pace of biological aging reflect developmental adaptations that may promote safety and provide other benefits for children raised in dangerous environments, they have been consistently associated with the emergence of multiple forms of internalizing and externalizing psychopathology and explain the link between childhood trauma exposure and transdiagnostic psychopathology. Children with higher levels of social support, particularly from caregivers, are less likely to develop psychopathology following trauma exposure. Caregiver buffering of threat-related processing may be one mechanism explaining this protective effect.

CONCLUSION

Childhood trauma exposure is a powerful transdiagnostic risk factor associated with elevated risk for multiple forms of psychopathology across development. Changes in threat-related social and emotional processing and accelerated biological aging serve as transdiagnostic mechanisms linking childhood trauma with psychopathology. These transdiagnostic mechanisms represent critical targets for early interventions aimed at preventing the emergence of psychopathology in children who have experienced trauma.

Coping Strategies and Psychological Symptoms Among Children on St. Thomas in the Aftermath of Hurricanes Irma and Maria

Research has shown that experiencing a hurricane can lead to internalizing, externalizing, and posttraumatic stress (PTS) symptoms in children. However, the effects of experiencing two hurricanes within a short time frame have not been examined. Moreover, there is limited research examining how children's coping is linked to their psychological functioning and no research using the empirically supported conceptualization of coping that includes primary control coping (i.e., attempts to control the stressor) and secondary control coping (i.e., attempts to adapt to the stressor). This study examined the psychological functioning of 108 children and adolescents (69.7% Black, Non-Hispanic; 56.5% female; M age = 11.59 years, SD = 2.43) in Grades 3-12 as measured 3 months after experiencing Hurricanes Irma and Maria on the island of St. Thomas. Participants completed electronic questionnaires about their demographic characteristics, hurricane exposure (i.e., perceived life-threat, life-threatening events, loss/disruption after hurricanes), coping strategies utilized, and their psychological functioning (i.e., PTS, internalizing, and externalizing symptoms). A principal component analysis of the coping items determined four coping factors: primary control, secondary control, disengagement, and negative coping. Linear regressions, including children's age and aspects of hurricane exposure, found primary control coping was positively associated with PTS symptoms, β = .18, whereas secondary control coping was negatively associated with PTS and externalizing symptoms, βs = -.17 and -.19, respectively. Negative coping, but not disengagement coping, was positively associated with all three outcomes, βs = .31-.42. These findings suggest positive ways children can cope after experiencing a hurricane, informing possible early intervention efforts.

Post-traumatic positive and negative psychological changes experienced by child and adolescent earthquake survivors in remote rural western China: a cross-sectional study six years after the Yushu earthquake

Background: Yushu, Qinghai province is located in remote Tibetan plateau in Western China, struck by a disastrous earthquake in 2010. The study aimed to find out the positive and negative psychological changes and related risk factors of children and adolescents who had experienced Yushu earthquake, 6 years after it occurred. Methods: A cross-sectional research was adopted in the capital of Yushu Autonomous Prefecture in August 2016. The short form of the Changes in Outlook Questionnaire (CiOQ-S) was used, which is a 10-item self-report instrument consists of two subscales. A total of 591 valid questionnaires completed by local junior students were finally included in our study. Results: The mean scores of the positive and negative psychological changes were 19.28 and 13.08, respectively. The factors associated with positive psychological changes included high level of education, male gender, and uninjured in the earthquake. The factors associated with negative psychological changes included living in a pasture instead of downtown, injured during the earthquake, and not receiving psychological counselling. Conclusions: The current analysis tries to investigate the long-term psychological effects of earthquakes among children and adolescents, which aims to improve the psychological health status for child and adolescent survivors of similar events.

Child and adolescent mental health amidst emergencies and disasters

The mental health of children and young people can be disproportionally affected and easily overlooked in the context of emergencies and disasters. Child and adolescent mental health services can contribute greatly to emergency preparedness, resilience and response and, ultimately, mitigate harmful effects on the most vulnerable members of society.

An Exploratory Trial of Cognitive-Behavioral vs Client-Centered Therapies for Child-Mother Dyads Bereaved from Terrorism

The study was an evaluation of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT; Cohen et al. 2017) with child-caregiver dyads who experienced the death of a loved one from terrorism, using a hybrid efficacy/effectiveness design in which there were no required minimum symptom levels. Forty children ages 4-17 years old whose fathers died in the line of duty on 9/11/2001 and their mothers participated in an RCT comparing TF-CBT and Client-Centered Therapy (CCT). At baseline, mothers' PTSD, depression, and prolonged grief symptoms were highly elevated, whereas children's were at normative levels. Using intent-to-treat analysis, condition-by-time interactions showed significantly greater symptom reduction for mothers receiving CBT than those receiving CCT. For the children, both treatments led to significant symptom improvements.

Annual Research Review: Rethinking childhood trauma-new research directions for measurement, study design and analytical strategies

Childhood trauma is a key modifiable risk factor for psychopathology. Despite significant scientific advances, traumatised children still have poorer long-term outcomes than nontraumatised children. New research paradigms are, thus, needed. To this end, the review examines three dominant assumptions about measurement, design and analytical strategies. Current research warns against using prospective and retrospective measures of childhood trauma interchangeably; against interpreting cross-sectional differences in putative mediating mechanisms between adults with or without a history of childhood trauma as evidence of longitudinal changes from pre-trauma conditions; and against directly applying explanatory models of resilience or vulnerability to psychopathology in traumatised children to forecast individual risk in unseen cases. The warnings equally apply to research on broader measures of adverse childhood experiences (ACEs). Further research examining these assumptions can generate new insights on how to prevent childhood trauma and its detrimental effects.

Development of trauma symptoms following adversity in childhood: The moderating role of protective factors

BACKGROUND

Although the buffering effect of protective factors on children's outcomes following exposure to adverse childhood experiences has been well documented, research gaps remain as to whether this buffering effect differs based on the type of adversity experienced (i.e., maltreatment versus household dysfunction).

OBJECTIVE

To examine whether protective factors moderate the association between cumulative adversity, as well as adversity subtypes (i.e., maltreatment and household dysfunction) and child trauma-related distress in a clinical sample referred for treatment following exposure to adversity.

PARTICIPANTS AND SETTING

One-hundred and seventy-six children (aged 3-18) referred to a child abuse treatment clinic and who's files were opened between January 2016 and June 2017 were included.

METHODS

Data were collected, extracted, and coded from clinical files using a standardized data extraction protocol. Protective factors included: using individual coping strategies, peer support, individual social skills, caregiver physical caregiving, caregiver psychological caregiving, and educational involvement.

RESULTS

Cumulative childhood adversity (b = .16, p = .04) positively predicted child trauma-related distress. The link between exposure to cumulative adversity and child trauma-related distress varied as a function of protective factors: there was a positive association between adversity and child trauma-related distress for children who had low levels of protective factors, but not for those with high levels of protective factors (b=-0.56, p=<.001). Similar findings were observed when data was stratified by maltreatment and household dysfunction.

CONCLUSIONS

Bolstering children's protective factors prior to, and during child abuse treatment, may reduce trauma-related distress following exposure to adversity.

Sensory Modulation in Children Exposed to Continuous Traumatic Stress

Preliminary evidence supports a possible association between post-traumatic stress disorder (PTSD) and sensory modulation disorder (SMD). Nevertheless, the research focusing on this relationship in children is notably limited. This study examined children with and without PTS symptoms, by comparing their mothers' perceptions of their responses to sensory events in daily life. Mothers of 134 non-referred children aged 5-11, exposed to continuous traumatic stress due to political violence, completed the UCLA-RI and the Short Sensory Profile questionnaires. Significant differences emerged between children with different levels of PTS symptoms in various sensory modalities. Furthermore, half of the symptomatic children had suspected clinically significant deficits in sensory processing. In addition, PTSD symptoms were significantly associated with most of the sensory processing scores. Logistic regression indicated that the overall sensory processing score was a significant predictor of group classification. The results indicate that children with PTS symptoms may be at increased risk for sensory processing deficits. Evaluation of sensory processing should be incorporated into the routine evaluation of this population in order to determine whether this is an additional factor contributing to a child's difficulties in participating in daily activities. Subsequent intervention programs should then address the multiple needs of these children.

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.

Post-traumatic stress disorder, emotional and behavioral difficulties in children and adolescents 2 years after the 2012 earthquake in Italy: an epidemiological cross-sectional study

Despite the occurrence of several earthquakes, only a few studies were conducted in Italy on the psychological impact in children and adolescents, with data mostly collected within one year after the disaster. This cross-sectional study aimed at exploring the prevalence of both post-traumatic stress disorder (PTSD) and emotional/behavioral difficulties, as well as at identifying their main predictors, among youths 2 years after the earthquake that hit Northern Italy in 2012. 682 children and adolescents (9-14 years) living in two districts (earthquake zone vs control zone) were administered an exposure questionnaire, the UCLA PTSD-Index for DSM-IV, and the Strengths and Difficulties Questionnaire (SDQ) and 1162 parents were assessed through the Symptom Checklist-90 (SCL-90). The prevalence of a likely PTSD in the earthquake zone was 1.9% (4.4% near the epicenter) and the total PTSD score in the affected area was significantly higher than in the control zone. 14.9% of youths living in the earthquake zone had a borderline/abnormal SDQ total difficulties score and 87.5% of youth with a likely PTSD also had a SDQ total score in the borderline/abnormal range. Regression analysis showed that the number of lifetime traumatic events (e.g., death of a relative) was the best predictor of children/adolescents psychological difficulties 2 years after the earthquake, followed by severity of exposure (personal injuries and losses) and parental psychopathology. Despite some limitations, this study highlights that youths may exhibit PTSD symptoms years after disasters, often in comorbidity with behavioral/emotional difficulties, stressing the need for long-term surveillance and interventions in exposed populations.

Development of an international data repository and research resource: the Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive

Background: Studies that identify children after acute trauma and prospectively track risk/protective factors and trauma responses over time are resource-intensive; small sample sizes often limit power and generalizability. The Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive was created to facilitate more robust integrative cross-study data analyses. Objectives: To (a) describe creation of this research resource, including harmonization of key variables; (b) describe key study- and participant-level variables; and (c) examine retention to follow-up across studies. Methods: For the first 30 studies in the Archive, we described study-level (design factors, retention rates) and participant-level (demographic, event, traumatic stress) variables. We used Chi square or ANOVA to examine study- and participant-level variables potentially associated with retention. Results: These 30 prospective studies (N per study = 50 to 568; overall N = 5499) conducted by 15 research teams in 5 countries enrolled children exposed to injury (46%), disaster (24%), violence (13%), traffic accidents (10%), or other acute events. Participants were school-age or adolescent (97%), 60% were male, and approximately half were of minority ethnicity. Using harmonized data from 22 measures, 24% reported significant traumatic stress ≥1 month post-event. Other commonly assessed outcomes included depression (19 studies), internalizing/externalizing symptoms (19), and parent mental health (19). Studies involved 2 to 5 research assessments; 80% of participants were retained for ≥2 assessments. At the study level, greater retention was associated with more planned assessments. At the participant level, adolescents, minority youth, and those of lower socioeconomic status had lower retention rates. Conclusion: This project demonstrates the feasibility and value of bringing together traumatic stress research data and making it available for re-use. As an ongoing research resource, the Archive can promote 'FAIR' data practices and facilitate integrated analyses to advance understanding of child traumatic stress.

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.
