Since children and adolescents often show a variety of internalizing and externalizing symptoms in the aftermath of traumatic events, the question arises whether such a conceptualization of the PTSD diagnosis is supported in children and adolescents. Furthermore, although dysfunctional posttraumatic cognitions (PTCs) appear to play an important role in the development and persistence of PTSD in children and adolescents, their function within diagnostic frameworks requires clarification. METHODS: We compiled a large international data set of 2,313 children and adolescents aged 6 to 18 years exposed to trauma and calculated a network model including dysfunctional PTCs, PTSD core symptoms and depression symptoms. Central items and relations between constructs were investigated. RESULTS: The PTSD re-experiencing symptoms strong or overwhelming emotions and strong physical sensations and the depression symptom difficulty concentrating emerged as most central. Items from the same construct were more strongly connected with each other than with items from the other constructs. Dysfunctional PTCs were not more strongly connected to core PTSD symptoms than to depression symptoms. CONCLUSIONS: Our findings provide support that a PTSD diagnosis reduced to its core symptoms could help to disentangle PTSD, depression and dysfunctional PTCs. Using longitudinal data and complementing between-subject with within-subject analyses might provide further insight into the relationship between dysfunctional PTCs, PTSD and depression.

Long-term associations between early attachment and parenting and adolescent susceptibility to post-traumatic distress in a South African high-risk sample / Sarah L. HALLIGAN ; Rachel M. HILLER ; Sarah SKEEN ; Mark TOMLINSON in Journal of Child Psychology and Psychiatry, 65-7 (July 2024)

HALLIGAN, Auteur ; Rachel M. HILLER, Auteur ; Sarah SKEEN, Auteur ; Mark TOMLINSON, Auteur Article en page(s) : p.921-931 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background It has been proposed that children and young people living in low- and middle-income countries (LMICs) are not only exposed more frequently to trauma but also have a higher likelihood of encountering traumas of greater severity than those living in high-income countries (HICs). This may lead to higher rates of post-traumatic stress symptoms (PTSS). However, developmental pathways to risk or resilience after trauma exposure in LMICs are underresearched. Methods We examined early parenting and attachment as potentially important formative factors for later stress reactivity in a longitudinal cohort of South African children (N = 449). Parenting and attachment were assessed at child age 18 months, and interpersonal trauma exposure, PTSS and parenting stress were measured at 13 years (N = 333; core sample with data on all measures: N = 213). Following a vulnerability-stress approach, separate regression models were run to investigate whether parent-child attachment at 18 months, parental sensitivity and intrusiveness during play at 12 months, and current parenting stress at 13 years, interacted with adolescents' extent of interpersonal trauma exposure to predict their PTSS levels at 13 years. Results We found no predictive effects of either early attachment or current parenting stress in relation to child PTSS. There was some evidence for predictive influences of parental early intrusiveness and sensitivity on adolescent outcomes, though associations were unexpectedly positive for the latter. No interaction effects supporting a vulnerability-stress model were found. Conclusions Overall, we found limited evidence that elements of the early parent-child environment predict child risk/resilience to trauma in LMIC children. Future studies should include more frequent assessments of relevant constructs to capture changes over time and consider further what comprises adaptive parenting in high-risk contexts.

A longitudinal investigation of the role of parental responses in predicting children's post-traumatic distress / Rachel M. HILLER in Journal of Child Psychology and Psychiatry, 59-7 (July 2018)

HALLIGAN, Auteur Article en page(s) : p.781-789 Langues : Anglais (eng) Mots-clés : Longitudinal  child  cognitive behavioural  parenting  post-traumatic stress disorder Index. décimale : PER Périodiques Résumé : BACKGROUND: While parental post-trauma support is considered theoretically important for child adjustment, empirical evidence concerning the specific aspects of parental responding that influence child post-traumatic distress, or the processes via which any such impacts occur, is extremely limited. We conducted a longitudinal examination of whether parental post-trauma appraisals, trauma-specific support style and general parenting style predicted child post-traumatic stress symptom severity (PTSS) following trauma; and whether such influences operated via the child's own appraisals and coping style. METHOD: We recruited 132 parent-child pairs following children's experience of acute trauma. We examined whether parental responses assessed at 1-month post-trauma, predicted child PTSS at 6-month follow-up. Parental trauma-specific appraisals and responses, and general parenting style, were assessed via both self-report and direct observations. Child-report questionnaires were used to assess PTSS and potential mediators. RESULTS: Initial parent negative appraisals and encouragement of avoidant coping were associated with higher child-reported PTSS at 6-month follow-up. Predictive effects were maintained even when controlling for initial child symptom levels. Observational assessments broadly supported conclusions from self-report. There was evidence that parental influences may operate, in part, by influencing the child's own appraisals and coping responses. In contrast, there was no evidence for an influence of more "adaptive" support or general parenting style on child PTSS. CONCLUSIONS: Findings provide important insight into how elements of social support may influence child post-trauma outcomes.

A longitudinal study of cognitive predictors of (complex) post-traumatic stress in young people in out-of-home care / Rachel M. HILLER in Journal of Child Psychology and Psychiatry, 62-1 (January 2021)

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.

Research Review: Changes in the prevalence and symptom severity of child post-traumatic stress disorder in the year following trauma – a meta-analytic study / Rachel M. HILLER in Journal of Child Psychology and Psychiatry, 57-8 (August 2016)

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.
