Parents are the primary source of support for their children and can become principal interventionists for preventing and treating their child's challenging behavior. Yet, providing adequate and adapted training for culturally diverse families can be difficult due to the increase of international migration and the diversity of languages spoken…

Despite the early onset of challenging behaviors, there is a lack of research investigating the function of challenging behavior in toddlers with autism spectrum disorder (ASD) and developmental disabilities (DDs). The current study evaluated group differences in the frequency and severity of five functions of challenging behavior (i.e.,…

We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical…

Children with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4-11 years) were…

Fragile X syndrome (FXS) and Smith-Magenis syndrome (SMS) are associated with a number of specific topographies of problem behavior. Very few studies have examined the function served by problem behavior in these groups. Using the Questions About Behavioral Function scale Matson and Vollmer (User's guide: questions about behavioral function…

A combination of behavioral and medication-based interventions has been the most effective form of treatment for reducing problem behavior in individuals with intellectual and developmental disabilities. Evaluating the 2 types of interventions in combination and separately may require that researchers adapt methods traditionally used to evaluate…

We conducted a systematic literature review of anger management in people with intellectual disabilities (ID). We identified 2 studies that used randomized controlled trials and 6 that used pretest-posttest nonequivalent control group designs. The mean between-group effect size was 1.52 for randomized controlled trials and 0.89 for the other…

A common recommendation for implementing time-out procedures is to include a release contingency such that the individual is not allowed to leave time-out until no problem behavior has occurred for a specific amount of time (e.g, 30 s). We compared a fixed duration time-out procedure to a release contingency time-out procedure with 4 young…

Parents of children with a developmental disability require tailored parenting support, as their families have special needs and are at risk of increased burden. The aim of this study was to evaluate the efficacy of the Stepping Stones Triple P seminars, a brief group intervention for parents of a child with a disability. There were two seminars…

Sleep problems have often been reported in children with intellectual disabilities (ID). How anomalies in 24-h sleep patterns relate to behaviour difficulties in children with different types of ID remains to be elucidated. The purpose of this study was to assess 24-h sleep and behaviour patterns in children with a variety disorders including…

A randomized controlled trial was used to evaluate a parent training intervention for caregivers with preschool-age children with developmental disabilities. The 21 families in the experimental group received usual care plus the 12-week Incredible Years Parent Training Program with developmental delay modifications. Families in the control group…

Many clients in Hong Kong with developmental disabilities stay in mental hospitals because of mental disorders and behavioural problems.
