Background: Children with intellectual disability (ID) are at risk for maladaptive development of social relatedness. Controversy exists whether Pervasive Developmental Disorder (PDD) takes precedence over disordered attachment for describing maladaptive social behaviour. The aim of this study was to assess the prevalence of disordered attachment…

Background: Virtually nothing is known about potential differences in the types of depression symptoms reported by adults with mild intellectual disability (ID) on self-reported questionnaires as compared with the types of symptoms reported by caregivers on informant questionnaires. Moreover, little is known about how the presentation of…

Background: The purpose of the current cross-sectional study was to examine the developmental progression in working memory (WM) between the ages of 9 and 16 years in a large sample of children with mild to borderline intellectual disabilities (MBID). Baddeley's influential WM model was used as a theoretical framework. Furthermore, the…

Background: Down syndrome (DS) affects not only children but also their families. Much remains to be learned about factors that influence how families of children with DS function, especially families in non-Western populations. The purpose of this cross-sectional, correlational study was to examine how family demographics, family demands and…

Background: It is unclear whether the substantial decline in number and duration of admissions for patients with intellectual disability (ID) have occurred uniformly over time with respect to age, gender, severity of disability, legal status and location of treatment. Method: A retrospective analysis of NHS (National Health Service) admissions for…

Background: Effective cancer screening must be available for all eligible individuals without discrimination. Lower rates of cervical and breast cancer screening have been reported in certain groups compared with women from the general population, such as women with intellectual and developmental disabilities (IDD). Research on the factors…

Background: Identification of possible personal indicators of risk for challenging behaviour has generally been through association in cross-sectional prevalence studies, but few analyses have controlled for intercorrelation between potential risk factors. The aim was to investigate the extent to which gender, age, presence of the triad of…

Background: Fathers have unique influences on children's development, and particularly in the development of social skills. Although father-child relationship influences on children's social competence have received increased attention in general, research on fathering in families of children with developmental delays (DD) is scant. This…

Background: People with developmental disabilities are at high risk for a limited participation in leisure activities. The aim of this study was to investigate the participation in, preference for and interest in leisure activities of young and adults with developmental disabilities, and to examine the factors associated with leisure activity.…

Background: There is conjecture regarding the profile of cognitive development over time in children with Down syndrome (DS). Characterising this profile would be valuable for the planning and assessment of intervention studies. Method: A systematic search of the literature from 1990 to the present was conducted to identify longitudinal data on…

Background: Public attitudes towards persons with intellectual disabilities (IDs) have a significant effect on potential community integration. A better understanding of these can help target service provision and public awareness programmes. Objectives: The objective of the present study is threefold: (1) describe public attitudes towards persons…

Background: Begun in the late 1990s, mental health courts are specialty criminal courts developed to address the needs of persons with mental illness. Methods: As many persons with intellectual disabilities (IDs) may overlap in the mental health court system, we used mental health court records to examine the phenomenology and outcomes of 224…

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: Intellectual disability (ID) accounts for 70% of all disabilities among children in China's Second National Sampling Survey on Disability. Although studies have shown a relationship between social class and ID in children, none have investigated the association of socioeconomic variables in Chinese children with mild or severe ID.…

Background: Previous studies in adults with intellectual disabilities (ID) have reported a higher prevalence of obesity than in the general population, and a trend to an increase in the prevalence of excess weight. However, little information is available on body weight status and lipids levels of adults with ID and co-existing mental illness. The…
