Titre : Child neglect and its relation to emotional and behavioral problems: A cross-sectional study of primary school-aged children in Tanzania Type de document : texte imprimé Auteurs : Tobias HECKER, Auteur ; Victoria S. BOETTCHER, Auteur ; Markus A. LANDOLT, Auteur ; Katharin HERMENAU, Auteur Article en page(s) : p.325-339 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Child maltreatment is known to engender negative emotional and behavioral consequences. Although neglect is the most frequent form of maltreatment, it has thus far only received little attention, especially when looking at low-resource countries. The current study investigated possible associations between neglect and internalizing and externalizing problems. As neglect and abuse often co-occur, the latter was controlled for. In total, 409 Tanzanian primary school students (52% boys, M = 10.5 years, range = 6–15) participated in the cross-sectional study. Structured clinical interviews were conducted assessing maltreatment, internalizing problems, and externalizing problems. Overall, 31% (n = 128) of the children reported at least one type of physical neglect and 31% (n = 127) of emotional neglect. Using structural equation modeling, we found a significant association between neglect and internalizing (β = 0.59, p < .01) and externalizing problems (β = 0.35, p < .05). However, these associations could only be detected in younger children (ages 6–9), whereas in older children (ages 10–15), mental health problems were significantly related to violence and abuse. Our findings suggest that the current age may influence the association between maltreatment type and the development of internalizing and/or externalizing problems.

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.

Titre : Preventive intervention for trauma reactions in young injured children: results of a multi-site randomised controlled trial Type de document : texte imprimé Auteurs : Ann-Christin HAAG, Auteur ; Markus A. LANDOLT, Auteur ; Justin A. KENARDY, Auteur ; Clemens M. SCHIESTL, Auteur ; Roy M. KIMBLE, Auteur ; Alexandra C. DE YOUNG, Auteur Article en page(s) : p.988-997 Langues : Anglais (eng) Mots-clés : Preventive intervention injury traumatic stress young children Index. décimale : PER Périodiques Résumé : BACKGROUND: Young children are at particular risk for injury. Ten per cent to twenty-five per cent develop posttraumatic stress disorder (PTSD). However, no empirically supported preventive interventions exist. Therefore, this study evaluated the efficacy of a standardised targeted preventive intervention for PTSD in young injured children. METHODS: Injured children (1-6 years) were enrolled in a multi-site parallel-group superiority prospective randomised controlled trial (RCT) in Australia and Switzerland. Screening for PTSD risk occurred 6-8 days postaccident. Parents of children who screened 'high-risk' were randomised to a 2-session CBT-based intervention or treatment-as-usual (TAU). Primary outcomes were PTSD symptom (PTSS) severity, and secondary outcomes were PTSD diagnosis, functional impairment and behavioural difficulties at 3 and 6 months postinjury using blinded assessments. Trials were registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000325606) and ClinicalTrials.gov (NCT02088814). Trial status is complete. RESULTS: One hundred and thirty-three children screened 'high-risk' were assigned to intervention (n = 62) or TAU (n = 71). Multilevel intention-to-treat analyses revealed a significant intervention effect on PTSS severity over time (b = 60.06, 95% CI: 21.30-98.56). At 3 months, intervention children (M = 11.02, SD = 10.42, range 0-47) showed an accelerated reduction in PTSS severity scores compared to control children (M = 17.30, SD = 13.94, range 0-52; mean difference -6.97, 95% CI: -14.02 to 0.08, p adj. = .055, d = 0.51). On secondary outcomes, multilevel analyses revealed significant treatment effects for PTSD diagnosis, functional impairment and behavioural difficulties. CONCLUSIONS: This multi-site RCT provides promising preliminary evidence for the efficacy of a targeted preventive intervention for accelerating recovery from PTSS in young injured children. This has important clinical implications for the psychological support provided to young children and parents during the acute period following a single-event trauma.

Titre : The mutual prospective influence of child and parental post-traumatic stress symptoms in pediatric patients Type de document : texte imprimé Auteurs : Markus A. LANDOLT, Auteur ; Eivind YSTRØM, Auteur ; Felix H. SENNHAUSER, Auteur ; Hanspeter E. GNEHM, Auteur ; Margarete E. VOLLRATH, Auteur Année de publication : 2012 Article en page(s) : p.767-774 Langues : Anglais (eng) Mots-clés : Trauma injury chronic illness post-traumatic stress disorder Index. décimale : PER Périodiques Résumé : Background: Previous studies found notable rates of post-traumatic stress symptoms (PTSS) and post-traumatic stress disorder (PTSD) in pediatric patients and their parents and suggest a significant association between child and parent PTSS. However, little is known about mutual influences between child and parental PTSS over time. This study prospectively examined the presence of PTSS and PTSD and the mutual influence of child and parental PTSS in a large sample of pediatric patients with different medical conditions.
Methods: A total of 287 children (aged 6.5–16 years) and their mothers (n = 239) and fathers (n = 221) were assessed at 5–6 weeks and 1 year after an accident or a new diagnosis of cancer or diabetes mellitus type 1 in the child.
Results: At the first assessment 11.1% and at the second assessment 10.2% of the children had moderate to severe PTSS. At 5–6 weeks 29.3% of mothers and 18.6% of fathers met criteria for PTSD. At 1 year the rates were 14.6% for mothers and 7.9% for fathers. There were considerable differences of PTSS among different medical diagnostic groups in children and parents. Mothers were more vulnerable than fathers. Structural equation analysis revealed that initially high PTSS in mothers and fathers were longitudinally related to poorer recovery from PTSS in the child. Cross-lagged effects from the child to the parents and from one parent to the other were not significant.
Conclusions: This study highlights the long-term influence of parental PTSS on the child’s recovery after trauma and calls for a family systems approach and for early interventions in the treatment of traumatized pediatric patients.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02520.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=166
