Introduction: This article describes the development of an Aggression and Restriction Observation Checklist (AROC) for use in residential and in-patient services for adults with intellectual disabilities (ID). The AROC was developed in collaboration between researchers and frontline staff. It assesses self-, person-, and object-directed aggressive…

Background: With the publication of the Developmental Behaviour Checklist for Adults (DBC-A), people of all ages with intellectual disability (ID) can now be assessed using a carer-completed screening checklist of emotional and behavioural disturbance. This provides a broad assessment framework across the life span, assists the process of clinical…

Students at risk for, or with, emotional disturbance during preadolescence struggle to adjust socially, behaviorally, and academically and often make choices about relationships that support problem behaviors. Research suggests explicitly teaching self-determination skills as early as preschool may prevent referral to special education with a…

There is a paucity of evidence concerning the patterns of multi-informant agreement in populations with Autism Spectrum Disorders (ASD). This study compared ratings of behaviour and emotional problems and social functioning provided by 45 adolescents aged 12-18 years, with Autistic or Asperger's Disorder with ratings by their parents and teachers.…

This study possessed 2 aims: (a) to develop and validate a clinician-friendly measure of academic problem behavior that is relevant to the assessment of adolescents with attention deficit/hyperactivity disorder (ADHD) and (b) to better understand the cross-situational expression of academic problem behaviors displayed by these youth. Within a…

The purpose of this demonstration was to evaluate a universal intervention during teacher-identified routines that were characterized by significant classwide problem behavior. Six Head Start classrooms (seven groups of children, with one classroom divided into two groups) received two workshops and two coaching sessions on universal Positive…

Research Findings: Preventing challenging behavior in young children is a national priority. The number of young children with behavioral problems is on the rise. Discipline policies can help early childhood programs build an infrastructure that promotes social and academic success. This study sought to document the extent to which existing early…

The study examines the agreement among raters on children's problematic behaviors. A multitrait-multimethod (MTMM) matrix was applied to a normative sample of elementary school-aged children (N = 841). The participants were rated by their physical educators, using the Motor Behavior Checklist for children (MBC; Efstratopoulou, Janssen, &…

Recently, several instruments have been developed to measure the subjective component of the quality of life (QOL) of people with profound intellectual and multiple disabilities (PIMD). A next step, however, must be the further validation of these instruments. The present study aimed at evaluating the psychometric properties of one of these…

Background: Achenbach & Rescorla (2003) recently developed the Adult Behavior Checklist (ABCL) to assess psychopathology in the general population. The ABCL should be completed by a proxy informant. The use of proxy informants, instead of self-reporting, makes the ABCL potentially suitable for the assessment of psychopathology in adults with…

Problem behavior is a major barrier to successful community integration for people with developmental disabilities. Recently, there has been increased interest in identifying contextual factors involving setting events and discriminative stimuli that impact the display of problem behavior. The authors previously developed the "Contextual…

Behavioral difficulties of school-aged students are typically dealt with in a reactive, rather than preventative manner. This article examines a proactive approach, consistent with the Response-to-Intervention model, using a screening measure designed to identify students at risk for behavior difficulties and targeting these students for early…

The behavior of each of 120 students in grades 9-12 was rated by 2 of the student's teachers using the Revised Behavior Problem Checklist. Results indicated a generally low to moderate degree of relationship among teacher ratings. It is recommended that clinicians collect behavioral ratings from many raters before reaching diagnostic conclusions.…

Problem behavior is a primary barrier to successful community inclusion for people with developmental disabilities and therefore a major priority for intervention efforts. Recently, researchers and clinicians have begun to focus on the systematic assessment of a broad range of contextual variables that purportedly affect problem behavior. In the…
