    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.</p

    Research Review: Changes in the prevalence and symptom severity of child posttraumatic stress disorder in the year following trauma – a meta-analytic study

    Objective: Understanding the natural course of child and adolescent posttraumatic stress disorder (PTSD) has significant implications for the identification of, and intervention for, at-risk youth. We used a meta-analytic approach to examine longitudinal changes in youth PTSD prevalence and symptoms over the first 12 months posttrauma. Methods: We conducted a systematic review to identify longitudinal studies of PTSD in young people (5–18 years old), excluding treatment trials. The search yielded 27 peer-reviewed studies and one unpublished dataset for analysis of pooled prevalence estimates, relative prevalence reduction and standardised mean symptom change. Key moderators were also explored, including age, proportion of boys in the sample, initial prevalence of PTSD and PTSD measurement type. Results: Analyses demonstrated moderate declines in PTSD prevalence and symptom severity over the first 3–6 months posttrauma. From 1 to 6 months posttrauma, the prevalence of PTSD reduced by approximately 50%. Symptoms also showed moderate decline, particularly across the first 3 months posttrauma. There was little evidence of further change in prevalence or symptom severity after 6 months, suggesting that it is unlikely a child would lose a PTSD diagnosis without intervention beyond this point. Conclusions: The current findings provide key information about the likelihood of posttrauma recovery in the absence of intervention and have important implications for our understanding of child and adolescent PTSD. Results are discussed with reference to the timing of PTSD screening and the potential role of early interventions. Findings particularly highlight the importance of future research to develop our understanding of what factors prevent the action of normal recovery from the ‘acute’ posttrauma period

    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 10-18 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 (i) maladaptive appraisals, (ii) memory quality, and (iii) 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 symptoms 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

    The validity and scalability of the theory-of-mind scale with toddlers and pre-schoolers

    Despite the importance of theory of mind (ToM) for typical development, there remain two key issues affecting our ability to draw robust conclusions. One is the continued focus on false-belief as the sole measure of ToM. The second is the lack of empirically validated measures of ToM as a broad construct. Our key aim was to examine the validity and reliability of the five-item ToM scale (Peterson, Wellman, &amp; Lui, 2005). In particular, we extended on previous research of this scale by assessing its scalability and validity for use with children from two years of age. Sixty-eight typically developing children (aged 24 to 61 months) were assessed on the scale’s five tasks, along with a sixth Sally-Anne false-belief task. Our data replicated the scalability of the five tasks for a Rasch- but not Guttman-scale. Guttman analysis showed a four-item scale may be more suitable for this age range. Further, the tasks showed good internal consistency and validity for use with children as young as two years of age. Overall, the measure provides a valid and reliable tool for the assessment of ToM, and in particular the longitudinal assessment of this ability as a construct

    Predictors of posttraumatic stress symptom trajectories in parents of children exposed to motor vehicle collisions

    Following child trauma, parents are at risk of developing posttraumatic stress disorder (PTSD), either owing to their direct involvement or from hearing of their child's involvement. Despite the potential impact of a parent's development of PTSD on both the parent and child, little is known about what may place a parent at increased risk.   METHOD: PTSD symptoms were assessed ≤4 weeks, 6 months, and 3 years post-trauma, along with a range of potential risk factors, in a sample of parents of 2-10-year-old children who were involved in a motor vehicle collision.   RESULTS AND CONCLUSIONS: Two symptom trajectories were identified: Those parents whose symptoms remained low across all time points and those whose symptoms remained elevated at 6 months post-trauma and declined by 3 years. Subjective threat, thought suppression, and maladaptive cognitions about damage to the child were identified as key predictors of poorer outcomes

    The influence of early familial adversity on adolescent risk behaviours and mental health: stability and transition in family adversity profiles in a cohort sample : Stability and transition in family adversity profiles in a cohort sample

    Although familial adversity is associated with poorer outcomes in childhood and adulthood, little research has looked at the influence of stability or transition between distinct familial adversity subgroups or the impact in adolescence. Using data from the 9-month, 3-, 5-, and 14-year time waves of the Millennium Cohort Study (n > 18,000), we used latent class analysis to identify distinct classes of early familial adversity (marital instability/conflict, "suboptimal" parenting, economic disadvantage, and parental mental health problems) and the impact of these adversity classes on adolescent (a) mental health (including self-harm), (b) risk taking, (c) criminality, and (d) victimization. Four profiles were identified largely differing on economic hardship, family composition, and parental conflict. Across the first three time points, 72% of the sample remained stable, with the remainder transitioning between classes. Adolescents in the higher risk groups (particularly categorized by economic hardship or high parental conflict) had poorer outcomes in adolescence. Transitioning to a higher adversity group at any time in the first 5 years was associated with poorer outcomes but was particularly pronounced when the transition occurred when the child was under 3 years. These findings demonstrate the broad consequences of early familial adversity and the need for targeted early support for at-risk families

    A longitudinal examination of heart-rate and heart rate variability as risk markers for child posttraumatic stress symptoms in an acute injury sample

    Heart rate (HR) alterations in the immediate aftermath of trauma-exposure have been proposed to be potentially useful markers for child and adolescent posttraumatic stress disorder (PTSD). However, it is not yet clear if this holds true for measures taken more distal to the trauma, and no studies have investigated the predictive validity of more sensitive HR variability (HRV) indices. We recruited 76 parent-child pairs (child age 6 to 13 years) after the child experienced a traumatic event leading to presentation at a hospital emergency department. At 1-month post trauma (T1), HR recordings were obtained at rest, and while children verbally recounted their traumatic experience, both alone and together with a parent. Child post-traumatic stress symptoms (PTSS) were assessed concurrently (T1), and at 3 (T2) and 6-month (T3) follow-ups. We found that for T1, elevated mean HR during trauma narratives, but not at baseline, was positively associated with PTSS, with some evidence that HRV-indices were negatively cross-sectionally associated with PTSS. Furthermore, T1 HR indices predicted PTSS at T2 and partially at T3, although these effects did not hold when T1 PTSS were added to the model. Findings suggest that, consistent with the adult literature, HR indices in children may be a concurrent marker of higher PTSS and may be predictive of longer term distress. The findings encourage further investigations that track child HR and HRV in relation to PTSS over time after trauma, in order to examine how biological profiles evolve in those with persistent symptoms
