The two purposes of the pre-post naturalistic research design were to: 1) Investigate the impact of positive behavioral interventions and supports (PBIS) on the behavioral functioning of students with emotional disturbance (ED) (N = 37) served in self-contained settings; and 2) examine the extent to which teacher fidelity of PBIS implementation…

Forty clinic-referred mothers completed questionnaires describing their children's problems, the mothers' parenting styles, and their everyday mindfulness. Psychometric analyses of the questionnaires showed mother reports to be internally consistent, except for one of the parenting style scales (i.e., permissive style). We dropped the scale and…

Theories and prior research have outlined a constellation of adolescent risk behaviors that tend to co-occur, reflecting a general pattern. Although their generality has largely been supported, there is some question about how to best study and portray the relationship among these behaviors. This study used data from a survey administered to high…

This study tests the hypothesis that 6-year longitudinal stability of behavioral and emotional problems would be greater for children ages 6 to 7 than for those ages 4 to 5 at Time 1. Six-year outcome data for a nationally representative sample of 4- to 7-year-olds (N = 733) were used to examine longitudinal stability of internalizing,…

We compared the results of a contingency space analysis (CSA) of behavior-consequence recordings to the results of functional analysis (FA) test conditions involving antecedent stimuli and verbal statements that both differed from and mimicked those in the natural environment. Three preschool children with autism spectrum disorder participated.…

Behavior problems were investigated in 342 6- to 18-year-old children adopted from psychosocially depriving Russian institutions that provided adequate physical resources but not consistent, responsive caregiving. Results indicated that attention and externalizing problems were the most prevalent types of behavior problems in the sample as a…

Background: Persons with intellectual disability (ID) and sleep problems exhibit more daytime challenging behaviours than persons with ID without sleep problems. Several anecdotal reports suggest that melatonin is not only effective in the treatment of insomnia, but also decreases daytime challenging behaviour. However, the effect of melatonin…

The aim of this study was to examine associations between ostracism, internalising problems, and threat to primary needs (belonging, control, self-esteem, meaningful existence) in children (N= 165, M age = 9 years). Ostracism was simulated experimentally using the Cyberball paradigm--a computer-based ball-throwing game--and threats to primary…

The involvement of paraprofessionals in the education of students with intellectual and developmental disabilities (IDD) has been both complex and controversial. Many scholars and advocates have raised concerns about the roles these staff members play in schools and the degree to which there is empirical support for their direct work with…

The goal of this study was to provide an in-depth examination of friendships within organized activities. The prevalence of friendships with co-participants, their quality and characteristics, and their associations with adjustment were investigated. A sample of 281 (60% girls) 8th grade adolescents reported their friendships, activities, and…

Background: Previous research on the etiology of ADHD symptoms suggests that neuropsychological differences may be present as early as birth; however, the diagnosis is typically not given until school age. This study aimed to (a) identify early behavioral and cognitive markers of later significant parent and/or teacher ratings of ADHD…

This article focuses on the application of functional behavioral assessment (FBA) to design a positive behavior intervention (PBI) for a boy with Duchenne muscular dystrophy (DMD) who encounters serious difficulties at the mainstream school because of behavioral problems and physical limitations. After the definition of problem behavior and its…

Mothers' distress is a correlate of their children's elevated behaviour problems and symptoms. Parenting practices have been shown to mediate these associations, but few studies have observed parenting or focused on parents at risk of child abuse. In this study of 269 high-risk mothers and their young children (M?=?4.2?years), structural…

Relations between mothers' tendency to comment appropriately on their 8-month-olds' internal states (mind-mindedness) and children's behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N = 171, 88 boys). Controlling for maternal depressive symptoms, perceived…

Background: Research on parents of children with intellectual disability (ID) has identified a range of risk and protective factors for parental well-being. In family research, the association between marital quality and depression is a vital field of investigation. Still little research has addressed how aspects of the couple relationship affect…
