Rates of post-traumatic stress disorder in trauma-exposed children and adolescents: meta-analysis

BACKGROUND It is unclear how many children and adolescents develop post-traumatic stress disorder (PTSD) after trauma. AIMS To determine the incidence of PTSD in trauma-exposed children and adolescents as assessed with well-established diagnostic interviews and to examine potential moderators of the estimate. METHOD A systematic literature search identified 72 peer-reviewed articles on 43 independent samples (n = 3563). Samples consisting only of participants seeking or receiving mental health treatment were excluded. Main analyses involved pooled incidence estimates and meta-analyses of variance. RESULTS The overall rate of PTSD was 15.9% (95% CI 11.5-21.5), which varied according to the type of trauma and gender. Least at risk were boys exposed to non-interpersonal trauma (8.4%, 95% CI 4.7-14.5), whereas girls exposed to interpersonal trauma showed the highest rate (32.9%, 95% CI 19.8-49.3). No significant difference was found for the choice of assessment interview or the informant of the assessment. CONCLUSIONS Research conducted with the best available assessment instruments shows that a significant minority of children and adolescents develop PTSD after trauma exposure, with those exposed to interpersonal trauma and girls at particular risk. The estimates provide a benchmark for DSM-5 and ICD-11.

Building child trauma theory from longitudinal studies: a meta-analysis.

Many children are exposed to traumatic events, with potentially serious psychological and developmental consequences. Therefore, understanding development of long-term posttraumatic stress in children is essential. We aimed to contribute to child trauma theory by focusing on theory use and theory validation in longitudinal studies. Forty studies measuring short-term predictors and long-term posttraumatic stress symptoms were identified and coded for theoretical grounding, sample characteristics, and correlational effect sizes. Explicit theoretical frameworks were present in a minority of the studies. Important predictors of long-term posttraumatic stress were symptoms of acute and short-term posttraumatic stress, depression, anxiety, and parental posttraumatic stress. Female gender, injury severity, duration of hospitalization, and elevated heart rate shortly after hospitalization yielded small effect sizes. Age, minority status, and socioeconomic status were not significantly related to long-term posttraumatic stress reactions. Since many other variables were not studied frequently enough to compute effect sizes, existing theoretical frameworks could only be partially confirmed or falsified. Child trauma theory-building can be facilitated by development of encouraging journal policies, the use of comparable methods, and more intense collaboration.

Supporting Children After Single- Incident Trauma: Parents’ Views

Objective. To strengthen trauma-informed health care by exploring parents’ experiences of assisting their child after single-incident trauma (eg, violence, accidents, and sudden loss). Method. Semistructured interviews with parents (N = 33) of 25 exposed children (8-12 years). Results. Responsive parenting after trauma emerged as a core theme, consisting of (a) being aware of a child’s needs and (b) acting on these needs. The authors identified 14 strategies, such as comparing behavior with siblings’ behavior and providing opportunities to talk. Parents felt that their capacity to be responsive was influenced by their own level of distress. Conclusion. The authors propose a model of Relational PTSD (posttraumatic stress disorder) and Recovery to assist health care professionals working with children exposed to trauma. The results also point to the need to recognize the challenge that parents face when supporting a child after traumatic exposure and to align more with parents about procedures that may cause the child to be reminded of the event.

Making a difference: towards a method for weighing the evidence in a qualitative synthesis.

OBJECTIVES In a qualitative synthesis, primary qualitative studies are integrated to develop a theory or evidence-based interventions. Until now, the strength of the evidence in the primary studies has not been taken into account in the outcome of the qualitative synthesis. In this paper, a method is developed and evaluated to assign weights to the findings of the qualitative studies using both the frequency and the quality of the reported results. METHOD Seventeen qualitative studies were retrieved in an illustrative example project on children and trauma. Findings were extracted from the primary studies with the use of coding which resulted in 14 themes. The quality of the studies was appraised using both expert judgement and a quality checklist. These outcomes are used to calculate the weights. RESULTS When the outcomes of the checklist appraisal are compared with those of the expert judgement, the effect on the strength of the evidence is virtually always in the same direction. We found that as the frequency with which a concept is studied is low, the strength of the evidence oftentimes decreases even further when using the quality of the results in the weighing process. CONCLUSIONS In the end, the outcomes of a critical appraisal affect the weight that is placed on particular studies. The use of a checklist is recommended because of its more distinguishing ability. The method that was developed for assigning weights to the evidence is discussed in light of both the quality appraisal in qualitative research and the objectives of qualitative synthesis.

Adverse Childhood Experiences, Support, and the Perception of Ability to Work in Adults with Disability

Objective To examine the impact of adverse childhood experiences (ACEs) and support on self-reported work inability of adults reporting disability. Participants Adults (ages 18–64) who participated in the Behavioral Risk Factor Surveillance System in 2009 or 2010 and who reported having a disability (n = 13,009). Design and Main Outcome Measures The study used a retrospective cohort design with work inability as the main outcome. ACE categories included abuse (sexual, physical, emotional) and family dysfunction (domestic violence, incarceration, mental illness, substance abuse, divorce). Support included functional (perceived emotional/social support) and structural (living with another adult) support. Logistic regression was used to adjust for potential confounders (age, sex and race) and to evaluate whether there was an independent effect of ACEs on work inability after adding other important predictors (support, education, health) to the model. Results ACEs were highly prevalent with almost 75% of the sample reporting at least one ACE category and over 25% having a high ACE burden (4 or more categories). ACEs were strongly associated with functional support. Participants experiencing a high ACE burden had a higher adjusted odds ratio (OR) [95% confidence interval] of 1.9 [1.5–2.4] of work inability (reference: zero ACEs). Good functional support (adjusted OR 0.52 [0.42–0.63]) and structural support (adjusted OR 0.48 [0.41–0.56]) were protective against work inability. After adding education and health to the model, ACEs no longer appeared to have an independent effect. Structural support remained highly protective, but functional support only appeared to be protective in those with good physical health. Conclusions ACEs are highly prevalent in working-age US adults with a disability, particularly young adults. ACEs are associated with decreased support, lower educational attainment and worse adult health. Health care providers are encouraged to screen for ACEs. Addressing the effects of ACEs on health and support, in addition to education and retraining, may increase ability to work in those with a disability.

Is traumatic stress research global? A bibliometric analysis

Background The representation of low- and middle-income countries (LMIC) in traumatic stress research is important to establish a global evidence base, build research capacity, and reduce the burden of unmet mental health needs around the world. Reviews of the traumatic stress literature up to 2002 showed trends toward globalization although LMIC were only marginally represented compared to high-income countries (HIC). Objective To examine the global nature of current traumatic stress research. In particular, we were interested in the extent to which traumatic stress research is: (1) conducted in LMIC, (2) conducted by LMIC researchers, and (3) accessible to them. Method Using the databases PubMed, PsychInfo, and PILOTS, we systematically searched for peer-reviewed articles on traumatic stress published in any language in the year 2012. Out of the 3,123 unique papers identified, we coded a random sample (N=1,000) for study, author, article, and journal characteristics. Results Although our sample involved research in 56 different countries, most papers (87%) involved research in HIC, with 51% of all papers describing studies in the United States. In 88% of the papers, the author team was affiliated with HIC only. Less than 5% of all author teams involved collaborations between HIC and LMIC researchers. Moreover, 45% of the articles on LMIC studies published by a HIC corresponding author did not involve any LMIC co-authors. LMIC researchers appeared to publish empirical studies in lower impact journals. Of the 1,000 articles in our sample, 32% were open access and 10% were made available via different means; over half of the papers were not accessible without subscription. Conclusions Traumatic stress research is increasingly global but still strongly dominated by HIC. Important opportunities to build capacity in LMIC appear to be missed. Implications toward more international traumatic stress research are discussed.

Measuring Posttraumatic Stress Reactions in Children: A Preliminary Validation of the Children's Responses to Trauma Inventory

The Children’s Responses to Trauma Inventory (CRTI) is a self-report measure for posttraumatic stress reactions in children. We validated the original CRTI through secondary data analysis of four clinical and nonclinical samples (N = 96) and expert consultation. After revision, the CRTI was further validated in 8- to 12-year-old traumatized children in the general population (N = 243). The original CRTI showed moderate to excellent reliability and both convergent and discriminant validity, but it also had limitations in formulation and scope of the items. The revised measure showed good to excellent reliability. Convergent validity was established against measures for posttraumatic stress and quality of life. These preliminary results must be confirmed in larger samples with more extensive analyses.

Topical Review: Families Coping With Child Trauma: A Naturalistic Observation Methodology

OBJECTIVE To introduce a novel, naturalistic observational methodology (the Electronically Activated Recorder; EAR) as an opportunity to better understand the central role of the family environment in childrens recovery from trauma. METHODS Discussion of current research methods and a systematic literature review of EAR studies on health and well-being. RESULTS Surveys, experience sampling, and the EAR method each provide different opportunities and challenges for studying family interactions. We identified 17 articles describing relevant EAR studies. These investigated questions of emotional well-being, communicative behaviors, and interpersonal relationships, predominantly in adults. 5 articles reported innovative research in children, triangulating EAR-observed behavioral data (e.g., on child conflict at home) with neuroendocrine assay, sociodemographic information, and parent report. Finally, we discussed psychometric, practical, and ethical considerations for conducting EAR research with children and families. CONCLUSIONS Naturalistic observation methods such as the EAR have potential for pediatric psychology studies regarding trauma and the family environment.

Children's Perspectives on Dealing With Traumatic Events

Understanding childrens recovery after trauma is considered important, but existing theories are mainly based on adult research. We carried out semistructured interviews with 25 purposively sampled children (8–12 years old) exposed to single-incident trauma. The children had been affected by the event itself but also by a long aftermath with secondary stressors. Most children had recovered gradually, were impressed by and benefited from the social support they received, and displayed a wide range of coping behaviors (categorized under concentrating on the normal and the positive, avoiding risks and reminders, actively working through trauma, seeking support). Current theories need child-focused adjustments.

Trauma Exposure in Primary School Children: Who Is at Risk?

In order to direct efforts to prevent children from being exposed to trauma and its psychosocial consequences, more knowledge is needed about which children are at risk. Therefore, we examined demographic risk factors for trauma exposure in a sample of Dutch primary school children in the general population (N = 1,770, mean age 10.24 years). Fourteen percent of the children reported exposure. Age was positively associated with exposure while sex, ethnicity, and region of residence did not emerge as significant risk factors. These results imply that prevention measures should be provided not only to groups of children who are traditionally considered vulnerable but broadly.
