Background: The positive impact of physical activity on health is widely known. A comparison between activPAL objective measures and International Physical Activity Questionnaire short form (IPAQ-SF) self-reported activity levels was completed with older adults with intellectual disability. Understanding differences between the two methodologies…

Across the United States, State Education Agencies (SEAs) are using tiered strategies, such as Multi-Tiered System of Supports (MTSS) frameworks, to ensure that all students, including diverse learners, receive equal, high-quality education. However, little is known about the extent to which SEAs are encouraging use of MTSS to address the needs of…

Background: Despite progress in implementing the rights outlined in the UN Convention on the Rights of Persons with Disabilities, individuals with intellectual disability encounter challenges in participating in daily life autonomously. Exclusion and stereotypes persist, impacting education, employment, and social participation. Inclusive sports…

Background: Aggressive incidents are common in people with intellectual disabilities. Therefore, we aimed to assess whether supplementation of multivitamins, minerals, and omega-3 fatty acids (FA) reduces aggressive incidents. Methods: We conducted a randomised, triple blind, placebo controlled, single crossover intervention trial. People with…

Introduction: There is considerable international research indicating health disparities between people with and without intellectual disabilities. It is important that comparative studies use representative population samples. This study compares a total administrative population of adults with intellectual disability to a random stratified…

Background: Current evidence indicates that intellectual disability and gender are both factors in differential usage of services. However, there are limited data about the demographic and service usage patterns of people with intellectual disability who use mental health services. This is particularly true in relation to women with intellectual…

Background: Maternal input plays an important role in influencing linguistic development during the first years of life, and it is evident that mothers adapt their language according to their child's characteristics. Recently, it was demonstrated that maternal input addressed to children with sex chromosome trisomies (SCTs) at 8 months of age is…

Urine-detecting alarms are prevalent in toilet training intervention research and clinical practice for individuals with intellectual and developmental disabilities, but the effects of urine alarms remain unclear. Urine alarms may function as punishing or reinforcing contingencies, or may merely alert trainers to accidents and improve treatment…

As a treatment for escape-maintained problem behavior, differential reinforcement of alternative behavior (DRA) is typically initiated by reinforcing compliance on a dense reinforcement schedule. This work schedule is then progressively thinned such that the individual is required to complete more work, up to some socially acceptable terminal…

We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which…

"DDX[subscript 3]X" variants are a common cause of intellectual disability (ID) in females, and have been associated with autism spectrum disorder and emotional-behavioural difficulties. In this study, we compared phenotypic data for 23 females with "DDX[subscript 3]X" variants, to 23 females with ID and other genetic…

High levels of parenting stress have been detected in mothers of children with Autism (ASD) and children with attention deficit hyperactivity disorder (ADHD) comparing with mothers of typically developing (TD) children. The current study explored the implications of social support (confidant and affective support) and child characteristics…

Background: Adults with an intellectual disability should be supported according to their individual needs. The perception of need, however, is influenced by the values and expectations of the judging person. Method: Using the Camberwell Assessment of Need for Adults with Developmental and Intellectual Disabilities, self- and proxy-rated needs of…

This study examined the similarities/differences between the social phenotypes of Williams syndrome (WS) and autism spectrum disorder (ASD). As cultural norms may affect symptom evaluation, this study administered the Social Responsiveness Scale-2 to Japanese individuals with WS (n = 78, 4.4-44.0 years) and ASD (n = 75, 4.7-55.4 years). The scores…

Background: Women with intellectual and developmental disabilities face poorer reproductive and pregnancy outcomes partially due to health care inequity. Our objective was to conduct a scoping review of reproductive and pregnancy related health care among women with intellectual and developmental disabilities. Methods: We systematically reviewed…
