This study investigated the effect of a mindfulness-based intervention on pathological symptoms in boys with externalised disorders. A total of 24 elementary school students with externalising disorders, diagnosed by completing the Child Behavior Checklist (CBCL), were randomly assigned to a mindfulness-based intervention for two months.

While a considerable number of youth with autism spectrum disorder exhibit impaired self-regulation (dysregulation), little is known about the neural correlates of dysregulation in autism spectrum disorder. In a sample of intellectually able boys with autism spectrum disorder (further categorized as those with and without dysregulation) and…

Aggression among youth is a public health problem that is often studied in the context of how youth interpret social information. Social cognitive factors, especially hostile attribution biases, have been identified as risk factors for the development of youth aggression, particularly across the transition to middle school. Parental behaviors,…

This study examines the concurrent and longitudinal relationships between reactive and proactive aggression and children's peer status. Participants were 94 Dutch elementary school-aged boys in self-contained special education classrooms for students with emotional/behavioral disorders (EBD) and 47 boys with no disabilities in general education…

A key component of Mode Deactivation Therapy (MDT) is the development of self-awareness and regulatory skills by the client with the aim of helping adolescent males with conduct disordered behaviors, including sexually inappropriate behaviors and emotional dysregulation. The goal includes altering specific behaviors to fall within socially…

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child…

Background: A functional polymorphism in the promoter region of the monoamine oxidizing gene "monoamine oxidase A" ("MAOA") has been associated with behavioral sensitivity to adverse environmental conditions in multiple studies (e.g., Caspi et al. 2002; Kim-Cohen et al., 2006). The present study investigates the effects of…

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial. Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children with aggressive behavior are inconsistent. The current study aimed to investigate whether…

This paper is an outpatient replication of Apsche, Bass, Jennings and Siv (2005) work which examined the effectiveness of Mode Deactivation Therapy (MDT) on adolescent conduct disordered males in an inpatient therapeutic setting. This research compared the effectiveness of MDT and Treatment as Usual (TAU) as treatments on adolescents with conduct…

This research study compared the efficacy of two treatment methodologies for adolescent males in residential treatment with conduct disorders and/or personality dysfunctions and documented problems with physical and sexual aggression. The results showed that Mode Deactivation Therapy, an advanced form of cognitive behavioral therapy based on…

This treatment research study extended the results of Apsche, Bass, Jennings, Murphy, Hunter, and Siv (2005), from behavioral data to standard measures of psychological distress. In Apsche, et. al. (2005) results suggest that Mode Deactivation Therapy (MDT) was more effective than Cognitive Behavior Therapy (CBT) and Social Skills Therapy (SST) in…

This research study compares the efficacy of Mode Deactivation Therapy (MDT), an advanced form of Cognitive Behavioral Therapy based on Beck's theory of modes, and standard Cognitive Behavioral Therapy (CBT) for adolescent males in residential treatment. The results showed MDT was superior to CBT in reducing both physical and sexual aggression and…

Current tools for assessing children's social behavior in school psychology research and practice typically do not adequately measure issues most salient for young girls (e.g., experiences of relational victimization). The relation among teacher, peer, and self-reports of relational and physical peer victimization was examined for 119 fourth grade…
