The sequelae of child maltreatment tend to extend current posttraumatic stress disorder (PTSD) symptoms. This study examined this assumption, hypothesizing that (a) PTSD and trauma-related symptoms are more severe after single trauma than after child maltreatment; (b) symptoms unrelated to trauma are more severe after child maltreatment than after single trauma; and (c) a comorbid association of clinical PTSD with trauma-related symptoms is more prevalent after single trauma, whereas a comorbid association of clinical PTSD with trauma unrelated symptoms is more prevalent after child maltreatment. The Trauma Symptom Checklist for Children (TSCC) assessed PTSD and trauma-related symptoms in 256 children (83 children exposed to single trauma, 173 to child maltreatment). The Strengths and Difficulties Questionnaire (SDQ) assessed trauma-unrelated symptoms. Single-trauma children reported significantly more severe PTSD and trauma-related symptoms. Significantly more severe trauma unrelated symptoms were reported after child maltreatment. A significant relation was found between clinical PTSD and more severe trauma-related symptoms in both samples. Likelihood of children meeting PTSD symptoms after trauma seems to decrease when traumatization becomes more complex. Findings support our assumption that symptomatology of maltreated children extends current PTSD symptoms.

BackgroundPrevious DSM-versions recognized an inhibited and a disinhibited subtype of the Reactive Attachment Disorder (RAD). The current DSM-5 distinguishes two different disorders, instead of two subtypes of RAD. This study examined whether a split-up of the subtypes is valid.MethodIn 126 foster children, attachment disorder symptoms were assessed with the Disturbances of Attachment Interview. Forms of pathogenic care were identified based on dossier analyses. Associations between symptoms of attachment disorder with internalizing and externalizing problems (Child Behavior Checklist and Teacher Report Form) were examined.ResultsOmnibus tests showed no significant association between type of symptoms and type of pathogenic care. Exploratory analyses did reveal an univariate association between disinhibited symptoms and history of physical abuse. Disinhibited symptoms were associated with more internalizing and externalizing problems (d’s < 0.50).ConclusionThe distinction of inhibited and disinhibited subtypes of RAD seems valid regarding their emotional and behavioral correlations. Whereas inhibited symptoms lack a correlation, disinhibited symptoms seem to have an externalizing and internalizing correlation.Trial registrationNTR1747

Multidimensional Treatment Foster Care (MTFC) has been shown to be an evidence based alternative to residential rearing and an effective method to improve behavior and attachment of foster children in the US. This preliminary study investigated an application of MTFC for preschoolers (MTFC-P) in the Netherlands focusing on behavioral outcomes in course of the intervention. To examine the following hypothesis: “the time in the MTFC-P intervention predicts a decline in problem behavior”, as this is the desired outcome for children assigned to MTFC-P, we assessed the daily occurrence of 38 problem behaviors via telephone interviews. Repeated measures revealed significant reduced problem behavior in course of the program. MTFC-P promises to be a treatment model suitable for high-risk foster children, that is transferable across centres and countries.Trial registrationNetherlands Trial Register: 1747.

Multidimensional Treatment Foster Care for Preschoolers (MTFC-P) has thus far only been tested for diminishing behavior problems in the US. This study tested relative efficacy of MTFC-P on multiple outcomes against treatment as usual in the Netherlands (TAU; Study I), and regular foster care (Study II). The sample included 55 children that received MTFC-P, 23 children received TAU and 30 children from regular foster care (RFC). Changes in behavioral and relationship functioning, trauma symptoms, hypothalamic-adrenal-pituitary (HPA-) axis functioning, and caregiving stress were assessed via questionnaires, interviews, and salivary cortisol. Outcomes of Study I were evaluated using a randomized controlled design and quasi-experimental design, outcomes of Study II according to non-equivalent group comparison. No evidence was found for relative efficacy of MTFC-P over TAU. A treatment effect was found on trauma symptoms, in favor of TAU. Outcomes of Study II revealed that whereas caregiving stress and secure base distortions were significantly more severe at baseline in MTFC-P compared to RFC, post treatment differences were no longer significant. However, percentages of symptoms of disinhibited attachment and attachment disorder were nearly equal between groups at baseline, while post treatment percentages indicated significantly more symptoms in MTFC. In addition, results revealed a significant difference in the severity of externalizing problems post treatment, in favor of RFC. The results obtained within this study indicate that children in MTFC-P and usual treatment foster care in the Dutch context improved similarly, thus not showing the same advantages that MTFC-P has demonstrated in the US. Results should be interpreted with caution due to lower than planned power. Findings underscore the challenges of testing novel treatments across contexts with highly different child welfare provisions.

BACKGROUND Disorders of attachment and social engagement have mainly been studied in children, reared in institutions and foster care. There are few studies amongst home reared children living with biological parents. The aim of this study was to test the clinical significance of inhibited attachment behaviour and disinhibited social engagement behaviour in young home reared children, referred for treatment of emotional and behavioural problems, compared with young children in treatment foster care. METHODS The Disturbances of Attachment Interview, Maltreatment Classification System, the Child Behaviour Checklist and Parenting Stress Index were used in 141 referred home reared children and 59 referred foster children, aged 2.0-7.9 years (M = 4.7, SE = 1.3), 71% boys. RESULTS Inhibited attachment behaviour was less prevalent in the referred home reared group (9%) than in the foster care group (27%). Disinhibited social engagement behaviour was found in 42% of the home reared group, similar to the foster care group. Inhibited attachment behaviour and disinhibited social engagement behaviour were not associated with child maltreatment. More inhibited attachment behaviour was associated with clinical levels of child internalizing and externalizing behaviour in the home reared group, not in the foster care group. In both groups, more disinhibited social engagement behaviour was associated with clinical levels of externalizing behaviour and with more parenting stress. CONCLUSIONS Even without evident links to maltreatment, results of this study suggest clinical significance of inhibited attachment behaviour and disinhibited social engagement behaviour in young home reared children referred for treatment of emotional and behavioural problems.

BackgroundThe large number of children that grow up in poverty is concerning, especially given the negative developmental outcomes that can persist into adulthood. Poverty has been found as a risk factor to negatively affect academic achievement and health outcomes in children. Interdisciplinary interventions can be an effective way to promote health and academic achievement. The present study aims to evaluate a school-based interdisciplinary approach on child health, poverty, and academic achievement using a mixed-method design. Generally taken, outcomes of this study increase the knowledge about effective ways to give disadvantaged children equal chances early in their lives.MethodsAn observational study with a mixed-methods design including both quantitative and qualitative data collection methods will be used to evaluate the interdisciplinary approach. The overall research project exists of three study parts including a longitudinal study, a cross-sectional study, and a process evaluation. Using a multi-source approach we will assess child health as the primary outcome. Child poverty and child academic achievement will be assessed as secondary outcomes. The process evaluation will observe the program’s effects on the school environment and the program’s implementation in order to obtain more knowledge on how to disseminate the interdisciplinary approach to other schools and neighborhoods.DiscussionThe implementation of a school-based interdisciplinary approach via primary schools combining the cross-sectoral domains health, poverty, and academic achievement is innovative and a step forward to reach an ethnic minority population. However, the large variety of the interventions and activities within the approach can limit the validity of the study. Including a process evaluation will therefore help to improve the interpretation of our findings. In order to contribute to policy and practice focusing on decreasing the unequal chances of children growing up in deprived neighborhoods, it is important to study whether the intervention leads to positive developmental outcomes in children.Trial registration(NTR 6571) (retrospectively registered on August 4, 2017).
