This multicenter randomized controlled trial investigated whether interactive virtual reality enhanced effectiveness of Cognitive Behavioral Therapy (CBT) to reduce children's aggressive behavior problems. Boys with aggressive behavior problems (N = 115; M  = 10.58, SD = 1.

Children with aggressive behavior problems may aggress for different reasons, requiring tailored assessment and treatment. The aim of this study was to test whether it is possible to detect distinct social information processing (SIP) profiles among boys with aggressive behavior problems. We therefore conducted Latent Profile Analyses on boys' SIP patterns assessed in interactive virtual reality.

Interventions for children's aggression typically target assumed underlying mechanisms, such as anger regulation and hostile intent attribution. The expectation here is that targeting these mechanisms will result in within-person changes in aggression. However, evidence for these mechanisms is mostly based on between-person analyses.

This study examined whether interactive Virtual Reality (VR) provides a more ecologically valid assessment of children's aggressive social information processing (SIP) and aggressive responses than a standard vignette-based assessment. We developed a virtual classroom where children could meet and play games with virtual peers. Participants were boys (N = 184; ages 7-13) from regular education and special education for children with disruptive behavior problems.

Evidence-based cognitive behavioral therapies (CBTs) for children with aggressive behavior problems have only modest effects. Research is needed into new methods to enhance CBT effectiveness. The aims of the present study were to (1) examine whether interactive virtual reality is a feasible treatment method for children with aggressive behavior problems; (2) investigate children's appreciation of the method; and (3) explore whether children's aggression decreased during the ten-session treatment.

Children's aggressive behaviour is partly determined by how they process social information (e.g., making hostile interpretations or aiming to seek revenge).

To test specific hypotheses about the relation between hostile intent attribution (HIA) and children's aggressive behavior, a multilevel meta-analysis was conducted on 111 studies with 219 effect sizes and 29.272 participants. A positive association between HIA and aggression was found, but effect sizes varied widely between studies.

How do children with aggressive behavior problems view themselves? The present research seeks to answer this question by examining the self-views (i.e., self-esteem and narcissism) of boys referred for disruptive behavior problems.

The course of proactive aggressive behavior may be affected by empathy in response to sadness and distress of others. The aim of the current study is to examine empathy in response to sadness and distress and its relation to proactive and reactive aggression in a clinical sample of children with externalizing behavior problems. At baseline (T1) and 12 months later (T2), parents and teachers of 104 six- and seven-year-old children completed the Instrument for Reactive and Proactive Aggression.

Objective: Individuals' lay beliefs about mental health problems and attitudes toward mental health care are thought to be influenced by the cultural background of these individuals. In the current study, we investigated differences between immigrant Dutch and native Dutch parents and adolescents in lay beliefs about emotional problems and attitudes toward mental health care. Additionally, among immigrant Dutch parents, we examined the associations between acculturation orientations and lay beliefs about emotional problems as well as attitudes toward mental health care.

Although immigrant adolescents are at least at equal risk of developing internalizing problems as their non-immigrant peers, immigrant adolescents are less likely to use mental health care. The present study is the first to examine ethnic differences in problem identification to find explanations for this disparity in mental health service use. Specifically, the extent to which emotional problem identification mediates the relationship between immigrant status and mental health service use for internalizing problems in three immigrant populations in the Netherlands (i.

Background: Since developmental psychologists are interested in explaining age and gender differences in depression across adolescence, it is important to investigate to what extent these observed differences can be attributed to measurement bias. Measurement bias may arise when the phenomenology of depression varies with age or gender, i.e.

Micro-finite element (micro-FE) analysis became a standard tool for the evaluation of trabecular bone mechanical properties. The accuracy of micro-FE models for linear analyses is well established. However, the accuracy of recently developed nonlinear micro-FE models for simulations of trabecular bone failure is not known.

Trabecular bone strength is marked not only by the onset of local yielding, but also by post-yield behavior. To study and predict trabecular bone elastic and yield properties, micro-finite element (micro-FE) models were successfully applied. However, trabecular bone strength predictions require micro-FE models incorporating post-yield behavior of trabecular bone tissue.

Due to remodeling of bone architecture, an optimal structure is created that minimizes bone mass and maximizes strength. In the case of osteoporotic vertebral bodies, however, this process can create over-adaptation, making them vulnerable for non-habitual loads. In a recent study, micro-finite element models of a healthy and an osteoporotic human proximal femur were analyzed for the stance phase of gait.

Continuum-level finite element (FE) models became standard computational tools for the evaluation of bone mechanical behavior from in vivo computed tomography scans. Such scans do not account for the anisotropy of the bone. Instead, local mechanical properties in the continuum-level FE models are assumed isotropic and are derived from bone density, using statistical relationships.

A three-dimensional digital image correlation technique is presented for strain measurements in open-cell structures such as trabecular bone. The technique uses high-resolution computed tomography images for displacement measurements in the solid structure. In order to determine the local strain-state within single trabeculae, a tetrahedronization method is used to fill the solid structure with tetrahedrae.
