Identifying youth at risk for difficulties following a traumatic event: pre-event factors are associated with acute symptomatology

Trauma in Context: an Integrative Treatment Model

Evidenced based trauma treatments benefit children, but they rarely suffice for youth with multiple and complex comorbidities. After the completion of standard treatments, many children continue to show residual social, behavioral, and emotional difficulties. Part of the difficulty is that while the literature on trauma describes numerous facets that contribute to the severity, expression, and outcomes of trauma exposure, clinical assessments and interventions do not sufficiently reflect that literature. Clinicians thus have little guidance on how to integrate the intricacies of client's circumstances into a trauma-informed framework. To expand the scope and efficacy of treatments and guide clinicians in selecting appropriate interventions, this paper explores factors associated with pretreatment traumatic responses and proposes an integrative treatment model that includes the trauma experience, itself, combined with pre- and post-trauma factors that are both internal and external to the child and family. Pre-trauma experiences influence the severity of traumatic responses, while post-trauma factors impact a person's ability to cope and recover. Both are important targets for direct intervention.

Resilience Following Child Maltreatment: Definitional Considerations and Developmental Variations

Resilience following childhood maltreatment has received substantial empirical attention, with the number of studies on this construct growing exponentially in the past decade. While there is ample interest, inconsistencies remain about how to conceptualize and assess resilience. Further, there is a lack of consensus on how developmental stage influences resilience and how protective factors affect its expression. The current systematic review uses a developmental lens to synthesize findings on resilience following child maltreatment. Specifically, this article consolidates the body of empirical literature in a developmentally oriented review, with the intention of inclusively assessing three key areas-the conceptualization of resilience, assessment of resilience, and factors associated with resilience in maltreatment research. A total of 67 peer-reviewed, quantitative empirical articles that examined child maltreatment and resilience were included in this review. Results indicate that some inconsistencies in the literature may be addressed by utilizing a developmental lens and considering the individual's life stage when selecting a definition of resilience and associated measurement tool. The findings also support developmental variations in factors associated with resilience, with different individual, relational, and community protective factors emerging based on life stage. Implications for practice, policy, and research are incorporated throughout this review.

Relationship between posttraumatic stress symptoms, caregiving response, and parent mental health in youth exposed to single incident trauma

BACKGROUND

Family factors may alter the risk of developing posttraumatic stress disorder (PTSD) or depression in young people after a traumatic event, but it is not clear which modifiable family variables can be addressed in psychological therapies. This study examined the relationships between family factors (Expressed Emotion [EE] and family accommodation) and psychopathology (posttraumatic stress symptoms; PTSS) in young people following a single incident trauma. Potential mediators of these relationships were also investigated.

METHOD

Sixty-six parent-child dyads (aged 8-17 years) were assessed within one month of attending an Emergency Department. Self-reported PTSS and perceived EE were assessed in young people. Parents' own PTSS, mood symptoms, EE, and accommodating behaviours were also assessed.

RESULTS

Cross-sectional analyses revealed that young person-perceived EE, parent-reported emotional over involvement (EOI) and accommodation behaviours significantly predicted higher PTSS in young people. The stress experienced as a consequence of EE mediated the relationship between young person-perceived EOI and PTSS in young people. Parental PTSS and anxiety were positively correlated with EOI and accommodation. Parental PTSS was not significantly associated with symptoms in young people.

CONCLUSIONS

The results support the hypothesis that EE and accommodation are positively associated with PTSS in young people in the month following a potentially traumatic event. Understanding the child in the context of their family environment and relationships offers an important framework for making sense of and facilitating adaptive adjustment following a traumatic event.

The Dynamic Relations Among Peritraumatic Posttraumatic Stress Symptoms: An Experience Sampling Study During Wartime

The associations among peritraumatic posttraumatic stress symptoms (P-PTSS) in the immediate aftermath of trauma exposure, including those in the posttraumatic stress disorder clusters of intrusions, avoidance, negative cognitions and mood (NCM), and arousal, might indicate mechanisms through which enduring PTSD develops. During a period of war, exposed participants (N = 181) were sent twice-daily questionnaires for 30 days via smartphone. We repeatedly assessed the predictive associations between the P-PTSS clusters over time. We performed a multilevel pathway analysis built of multiple triple sequence responses (6,221 cases) on each of the four P-PTSS clusters at a mean time lag of 12 hr (Model A) and 24 hr (Model B) for 181 participants, 85 of whom had been diagnosed with a serious mental illness. Arousal predicted intrusion in Models A and B, b_A = 0.08, 95% CI [0.03, 0.12], p < .001 and b_B = 0.03, 95% CI [0.00, 0.07], p = .051, respectively; and NCM in Models A and B, b_A = 0.09, 95% CI [0.05, 0.12], p < .001 and b_B = 0.06, 95% CI [0.03, 0.09], p < .001, respectively. Intrusion predicted arousal in Model B, b_B = 0.05, 95% CI [0.01, 0.08], p = .010. NCM predicted arousal, b_A = 0.10, 95% CI [0.05, 0.14], p < .001, and avoidance b_A = 0.05, 95% CI [0.00, 0.11], p = .052, in Model A. Avoidance did not predict any other cluster. Arousal seemed to be acting as a hub, strengthening feedback loops to and from NCM and intrusion.

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.

Examining the Contemporaneous, Short-Term, and Long-Term Effects of Secondary Exposure to Violence on Adolescent Substance Use

The relationship between secondary exposure to violence-defined as witnessing violence in the home, community, or school-and adolescent substance use is well-documented. Yet, multi-wave empirical studies examining this relationship are sparse. In addition, studies have only begun to examine whether this relationship varies by the situational components of the violent event. Using data from the Project on Human Development in Chicago Neighborhoods (PHDCN), this study examines the contemporaneous, short-term, and long-term effects of secondary exposure to violence on substance use, and whether witnessing violence in which a weapon is present has a different impact on adolescent substance use than does witnessing violence without a weapon. Hierarchical logistic regression models on a racially and ethnically diverse sample of 1670 youth (51.5% female) residing in 79 neighborhoods indicated that: (1) the effects of secondary exposure to violence on alcohol and marijuana use were enduring, albeit attenuated, over time; (2) the effect of secondary exposure to violence on illicit drug use was suppressed in the short-term but significant in the long-term; (3) witnessing violence without a weapon was salient for alcohol and marijuana use at all time points; and (4) witnessing violence with a weapon impacted illicit drug use in the long-term. The results suggest that addressing the consequences of secondary exposure to violence requires prolonged intervention efforts and that the study of secondary exposure to violence requires a more nuanced approach that accounts for situational aspects of the violent event.

Psychological therapies for children and adolescents exposed to trauma

BACKGROUND

Children and adolescents who have experienced trauma are at high risk of developing post-traumatic stress disorder (PTSD) and other negative emotional, behavioural and mental health outcomes, all of which are associated with high personal and health costs. A wide range of psychological treatments are used to prevent negative outcomes associated with trauma in children and adolescents.

OBJECTIVES

To assess the effects of psychological therapies in preventing PTSD and associated negative emotional, behavioural and mental health outcomes in children and adolescents who have undergone a traumatic event.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Group's Specialised Register to 29 May 2015. This register contains reports of relevant randomised controlled trials from The Cochrane Library (all years), EMBASE (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). We also checked reference lists of relevant studies and reviews. We did not restrict the searches by date, language or publication status.

SELECTION CRITERIA

All randomised controlled trials of psychological therapies compared with a control such as treatment as usual, waiting list or no treatment, pharmacological therapy or other treatments in children or adolescents who had undergone a traumatic event.

DATA COLLECTION AND ANALYSIS

Two members of the review group independently extracted data. We calculated odds ratios for binary outcomes and standardised mean differences for continuous outcomes using a random-effects model. We analysed data as short-term (up to and including one month after therapy), medium-term (one month to one year after therapy) and long-term (one year or longer).

MAIN RESULTS

Investigators included 6201 participants in the 51 included trials. Twenty studies included only children, two included only preschool children and ten only adolescents; all others included both children and adolescents. Participants were exposed to sexual abuse in 12 trials, to war or community violence in ten, to physical trauma and natural disaster in six each and to interpersonal violence in three; participants had suffered a life-threatening illness and had been physically abused or maltreated in one trial each. Participants in remaining trials were exposed to a range of traumas.Most trials compared a psychological therapy with a control such as treatment as usual, wait list or no treatment. Seventeen trials used cognitive-behavioural therapy (CBT); four used family therapy; three required debriefing; two trials each used eye movement desensitisation and reprocessing (EMDR), narrative therapy, psychoeducation and supportive therapy; and one trial each provided exposure and CBT plus narrative therapy. Eight trials compared CBT with supportive therapy, two compared CBT with EMDR and one trial each compared CBT with psychodynamic therapy, exposure plus supportive therapy with supportive therapy alone and narrative therapy plus CBT versus CBT alone. Four trials compared individual delivery of psychological therapy to a group model of the same therapy, and one compared CBT for children versus CBT for both mothers and children.The likelihood of being diagnosed with PTSD in children and adolescents who received a psychological therapy was significantly reduced compared to those who received no treatment, treatment as usual or were on a waiting list for up to a month following treatment (odds ratio (OR) 0.51, 95% confidence interval (CI) 0.34 to 0.77; number needed to treat for an additional beneficial outcome (NNTB) 6.25, 95% CI 3.70 to 16.67; five studies; 874 participants). However the overall quality of evidence for the diagnosis of PTSD was rated as very low. PTSD symptoms were also significantly reduced for a month after therapy (standardised mean difference (SMD) -0.42, 95% CI -0.61 to -0.24; 15 studies; 2051 participants) and the quality of evidence was rated as low. These effects of psychological therapies were not apparent over the longer term.CBT was found to be no more or less effective than EMDR and supportive therapy in reducing diagnosis of PTSD in the short term (OR 0.74, 95% CI 0.29 to 1.91; 2 studies; 160 participants), however this was considered very low quality evidence. For reduction of PTSD symptoms in the short term, there was a small effect favouring CBT over EMDR, play therapy and supportive therapies (SMD -0.24, 95% CI -0.42 to -0.05; 7 studies; 466 participants). The quality of evidence for this outcome was rated as moderate.We did not identify any studies that compared pharmacological therapies with psychological therapies.

AUTHORS' CONCLUSIONS

The meta-analyses in this review provide some evidence for the effectiveness of psychological therapies in prevention of PTSD and reduction of symptoms in children and adolescents exposed to trauma for up to a month. However, our confidence in these findings is limited by the quality of the included studies and by substantial heterogeneity between studies. Much more evidence is needed to demonstrate the relative effectiveness of different psychological therapies for children exposed to trauma, particularly over the longer term. High-quality studies should be conducted to compare these therapies.

PTSD, cyberbullying and peer violence: prevalence and correlates among adolescent emergency department patients

OBJECTIVE

Posttraumatic stress disorder (PTSD) is often underdiagnosed and undertreated among adolescents. The objective of this analysis was to describe the prevalence and correlates of symptoms consistent with PTSD among adolescents presenting to an urban emergency department (ED).

METHODS

A cross-sectional survey of adolescents aged 13-17 years presenting to the ED for any reason was conducted between August 2013 and March 2014. Validated self-report measures were used to measure mental health symptoms, violence exposure and risky behaviors. Multivariate logistic regression analysis was performed to determine adjusted differences in associations between symptoms consistent with PTSD and predicted correlates.

RESULTS

Of 353 adolescents, 23.2% reported current symptoms consistent with PTSD, 13.9% had moderate or higher depressive symptoms and 11.3% reported past-year suicidal ideation. Adolescents commonly reported physical peer violence (46.5%), cyberbullying (46.7%) and exposure to community violence (58.9%). On multivariate logistic regression, physical peer violence, cyberbullying victimization, exposure to community violence, female gender and alcohol or other drug use positively correlated with symptoms consistent with PTSD.

CONCLUSIONS

Among adolescents presenting to the ED for any reason, symptoms consistent with PTSD, depressive symptoms, physical peer violence, cyberbullying and community violence exposure are common and interrelated. Greater attention to PTSD, both disorder and symptom levels, and its cooccurring risk factors is needed.
