Identifying and measuring anxiety in young people on the autism spectrum can be challenging. The present study investigated the use of the Anxiety Scale for Children with Autism Spectrum Disorder (ASC-ASD), a self- and caregiver-rated screening tool in a Singaporean sample of ninety-one verbal autistic youths and their caregivers. Internal…

This study examined age trends in anxious and depressive symptoms, from older adolescence to old age, and explored the association between anxious and depressive symptoms with gender, ASD severity, and socio-economic factors. Two hundred and fifty-five individuals with ASD (151 males, M[subscript age] = 33.52 years, SD[subscript age] = 14.98) took…

Anxiety-related problems are among the most frequently reported mental health difficulties in autism spectrum disorder. As most research has focused on clinical samples or high-functioning children with autism spectrum disorder, less is known about the factors associated with anxiety in community samples across the ability range. This…

Increasing numbers of students with Autism Spectrum Disorder (ASD) are attending mainstream schools. Nonetheless, concerns about their emotional well-being and mental health in these settings have also been raised.

This study investigated the use of the Spence Children's Anxiety…

Background: The prevalence of autism spectrum disorder (ASD) symptomatology is comparatively high in Cornelia de Lange syndrome (CdLS). However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. In this study we examine the ASD profile in CdLS in…

This study examined the duration of the diagnostic period, the number of professionals consulted, the relationship with the professional(s) and the perceived helpfulness of information provided…

There are few long-term follow-up studies of children with Autism Spectrum Disorders (ASD) who attended intensive intervention programmes in their pre-school years. Thirty-six children with ASD enrolled in relatively intensive, specialist pre-school programmes (minimum of 15 h intervention per week for 2 years at a mean age of 3.4 years) were…

This study examined the stability of scores on the ADI-R from pre-school to elementary school age in children with autism spectrum disorders (ASD). Participants were 35 children who, at T1, all had a clinical diagnosis of ASD. On initial assessment (mean age 3.5 years; SD 0.6 years), all met ADI-R algorithm criteria for autism. ADI-R assessments…
