Background: Sleep problems have an impact on executive functioning in the general population. While children with Down syndrome (DS) are at high risk for sleep problems, the impact of these sleep problems on executive functioning in school-age children with DS is less well documented. Our study examined the relationship between parent-reported and…

Background: The aim of the current study was to identify functional predictors of perceived impact of childhood disability among families of children with neurodevelopmental disorders and disabilities. We first examined the relationship between sub-domains of adaptive and problematic behaviour and perceived family impact. Second, we examined…

Background: Despite the benefits of social participation, children and adolescents with developmental disabilities (DD) are often excluded from taking part in social activities. There is a gap in the literature about the factors that contribute to adequate participation of children with severe DD in particular and the barriers to their…

Background: Girls with fragile X syndrome (FXS) have a wide range of cognitive and language abilities. The range of language outcomes experienced by girls with FXS, however, has been relatively unexplored. The purpose of this exploratory study was to examine receptive and expressive language, with a focus on vocabulary and syntax, in a group of…

Background: While behavioural abnormalities are fundamental features of Rett syndrome (RTT), few studies have examined the RTT behavioural phenotype. Most of these reports have focused on autistic features, linked to the early regressive phase of the disorder, and few studies have applied standardised behavioural measures. We used a battery of…

Background: This study aimed to explore the factors that predict functioning in families with a child with Down syndrome using a mixed methods design. The quantitative component examined the effect of maladaptive and autism-spectrum behaviours on the functioning of the family while the qualitative component explored the impact of having a child…

Background: The importance of positive parent-adolescent relationships is stressed in research on adolescents, although very little is known about this relationship when a teen has developmental disabilities (DD). We investigated the relationships of adolescents with disabilities with their mothers and their fathers in order to answer a number of…

Background: Males with fragile X syndrome and autism (FXS/autism) represent a distinct subgroup of males with FXS at risk for markedly poorer outcomes. Early identification and intervention can improve outcomes for males with autism spectrum disorder. Method: To advance the development of a specialised autism screening tool for young males with…

Background: This study examined whether service utilisation among children with intellectual disability (ID) varied by ethnic cultural group. Method: Survey carried out in four special schools in London. Information was provided by school teachers using case files, and 242 children aged 7 to 17 years with mild and moderate ID were identified.…

The study of the behaviour profile in subjects with Prader-Willi Syndrome (PWS). A total of fifty-eight 3- to 29-year-old subjects with PWS were studied using a standardized parent report of behavioural and emotional disturbances. There was an increase of behavioural and emotional disturbances for the adolescent and young adult age range, whereas…
