Purpose: To compare functioning and environmental aspects before and during physical distancing (DPD) and to determine which social, physical, behavioral and functioning aspects of DPD are correlated. Methods: Sixteen parents of children/adolescents with Down syndrome (11.38 ± 3.00 years) were surveyed before and DPD. Paired t-tests were used to…

This study describes the profile of repetitive behaviour in individuals with Williams syndrome, utilising cross-syndrome comparisons with people with Prader-Willi and Down syndromes. The Repetitive Behaviour Questionnaire was administered to caregivers of adults with Williams (n = 96), Prader-Willi (n = 103) and Down (n = 78) syndromes. There were…

Background: Recent research suggests that around 16% to 18% of children with Down syndrome (DS) also meet diagnostic criteria for autism spectrum disorder (ASD). However, there are indications that profiles of autism symptoms in this group may vary from those typically described in children with ASD. Method: Rates of autism symptoms and emotional…

Introduction: Children and young adults with Down syndrome can demonstrate increased behavior problems compared to their typically developing peers through childhood and adolescence. Though current tools measure behavior problems in persons with intellectual disabilities, they do not capture all the behavioral problems that can occur in…

Background: Sleep affects children's cognitive development, preparedness for school and future academic outcomes. People with Down syndrome (DS) are particularly at risk for sleep-disordered breathing (SDB). To our knowledge, the association between SDB and cognition in preschoolers with DS is unknown. Methods: We assessed sleep by using…

The study was performed in St. Petersburg in 2015 and comprised 34 children with diagnosed Down's syndrome (DS) aged 9-15 (mean 11) years (17 boys, 17 girls) who attended special schools. Control group was made up of 34 clinically healthy normal intelligence schoolchildren matched for age, sex and geographical distribution. The mothers were…

Although mothers of children with intellectual and developmental disabilities (IDD) experience high levels of stress and schools constitute an important resource, the relation remains unknown between maternal stress and educational services. Responding to a national, web-based survey, 965 mothers of students with disabilities completed a 163-item…

We evaluated the proportion of individuals with Down syndrome (DS: N = 108) who met criteria for autism spectrum disorder (ASD) on the Social Communication Questionnaire and the severity of ASD-related symptomatology in this group. The proportions of individuals with DS meeting the cut-off for ASD and autism in this sample were 19% and 8%,…

Little is known about the behavioral characteristics of adults with Down syndrome (DS) without dementia. The main purpose of this study was to investigate the psychopathology and social behavior among adults with DS compared to adults with nonspecific intellectual disability (NSID). Thirty-four adults with DS were individually matched with 34…

Background: Autism spectrum disorder (ASD) has been identified as a risk marker for self-injurious behaviour. In this study we aimed to describe the prevalence, topography and correlates of self-injury in individuals with ASD in contrast to individuals with Fragile X and Down syndromes and examine person characteristics associated with self-injury…

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: Having children with intellectual disability can be stressful for most parents. Currently there are very few studies focusing on parenting stress among mothers of children with Down syndrome (DS) in Asia. The present study examined the level of parenting stress experienced by Malaysian mothers of children with DS and evaluated the…

Background: Can ratings of temperament be a way of identifying young children with intellectual disabilities (ID) who are at risk for being experienced as difficult? We aimed to explore parents' reports of temperament in their young children with or without ID, as well as positive and negative impact of the child on parents. Method: Mothers and…

Routinized and compulsive-like behaviors (RCB) are common in typically developing children and in children and adults with Down syndrome, but what functions do they serve? Parents completed questionnaires for RCB, behavior problems, and adaptive behaviors. Children who had Down syndrome had significantly higher levels of RCB than did the typically…
