Anxiety is now recognized as one of the most common co-occurring conditions in youth diagnosed with autism spectrum disorder (ASD). Despite the prevalence of this comorbid condition, accurate assessment and diagnosis of anxiety in ASD has proven difficult. This paper will address the considerable research literature on assessing anxiety in youth…

Background: Children with intellectual disability are at greater risk of developing anxiety than the general population. Limited research has examined the challenges associated with recognising and responding to anxiety in children with intellectual disability, and its perceived impact. Aim: This study aimed to explore anxiety in children with…

People with intellectual disabilities (ID) are vulnerable to multiple long-term conditions (MLTC). However, in the UK, there are no individual strategies tailored for them. This study synthesised evidence on prevalence of MLTC in people with ID alongside risk factors, outcomes and preventative strategies. The scoping review used the tool Abstrackr…

This study examines the cost effectiveness of two interventions for disruptive behavior problems: First Step Next (FSN), a school-based intervention, and a multicomponent intervention that combined FSN with a home-based intervention, homeBase (hB). Analyses were based on findings from a large-scale comparative efficacy trial in the United States…

The purpose of this study was to investigate short-term changes of frailty in adults and identify predictors of frailty and disability changes between baseline and the follow-up. A cohort study was conducted in 85 adults with intellectual disability (ID) in southern Taiwan. Variables of frailty phenotype, Barthel Index, fall, comorbidity, and…

Recent research has suggested that people with autism spectrum disorder may be disproportionately at risk of substance use disorders. This study analyzed national-level Medicaid Claims data to compare substance use disorder prevalence among Medicaid enrollees with autism spectrum disorder (N = 388,426) and a random sample of enrollees without…

Examining the quality of life outcomes and supports of autistic people, particularly without proxies, is important to inform research and service delivery -- not only for it to be more evidenced-based, but also to ensure services and supports are successfully supporting autistic people in ways that are important to them. The aim of this…

To improve mental health care for autistic adults, a better understanding of their real-world intervention use is required. The aim of this study is to investigate individual differences in the intervention trajectories of autistic adults, by examining longitudinal patterns of therapy, counseling, and medication use. Self-reported intervention use…

Background: Previous studies indicate that a subset of children with Tourette syndrome (TS) experiences communication difficulties; however, the specific characteristics of these challenges remain underexplored. Aims: This study aimed to (1) quantify the proportion of children with TS within a North American cohort exhibiting communication…

People with intellectual and developmental disabilities (IDD) often have higher rates of comorbid mental health conditions compared to the general population. Yet, many people with IDD also have unmet needs for mental and behavioral health services. The aim of this study was to examine how states provided mental and behavior health, and crisis…

Anticipatory planning, that is, the ability to process information in advance to prepare to act, underpins activities that unfold in time, such as spoken language, reading and handwriting. One key, though not the only, mechanism that may facilitate anticipatory planning is rhythm, which is understood as the structured grouping of events in time.…

Background: Sleep problems are common in adults with ADHD and may be bidirectionally associated with ADHD severity and other psychiatric symptoms. We investigated the prevalence of positive screenings for various sleep disorders, and their association with psychiatric comorbidities in a large sample of adults with ADHD from a specialized…

There is a long tradition of research into autistic people's executive function skills. Yet, despite decades of research on EF in autism, the existing literature remains contradictory and 'confusing', with a large -- and unresolved -- discrepancy between small-to-moderate effect sizes demonstrated on laboratory-based EF tasks and large effect…

Analysing language characteristics and understanding their dynamics is the key for a successful intervention by speech and language therapists (SLT). Thus, this review aims to investigate a possible overlap in language development shared by autism spectrum disorders (ASD), specific language impairment (SLI) and social (pragmatic) communication…

Motor stereotypies are frequently reported in individuals with autism spectrum disorder, but determinants of stereotypies remain poorly understood. In this study, a randomized sample of children with diagnosis of autism spectrum disorder was investigated to identify the prevalence and determinants of stereotypies. A total of 134 children who…
