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 aimed to compare symptoms of autism spectrum disorder using the Childhood Autism Rating Scale (CARS) and the Social Responsiveness Scale (SRS™-2) and to investigate their influencing factors. The diagnostic agreement was 92.7%, but with a fair Kappa value (0.247). Children's verbal comprehension was related to the CARS scores, and no…

We determined inter-rater agreement for the VB-MAPP, an instrument sometimes used in planning educational goals and evaluating intervention effects for young people with autism. A pair of raters independently rated each of 32 children diagnosed with autism. Intraclass correlation coefficients for the total Milestones and Barrier scores were 0.876…

Communication Complexity Scale (CCS) scores for 269 minimally verbal participants were examined to determine if communicator behavior and task and communicator characteristics were related to scores in a manner consistent with theoretical and research evidence expectations. Each participant completed an interactive assessment with 6 joint…

This study assessed the utility of a brief assessment (the Peabody Picture Vocabulary Test-4th Edition; PPVT4) as a proxy for verbal IQ (VIQ) in large-scale studies of autism spectrum disorder (ASD). In a sample of 2,420 proband with ASD, PPVT4:IQ correlations were strong. PPVT4 scores were, on average, 5.46 points higher than VIQ; 79% of children…

We conducted a meta-analysis of 18 studies to establish whether a relation exists between Reading the Mind in the Eye Test (RMET) performance and intelligence quotient (IQ) in individuals diagnosed with autism-spectrum disorders (ASD) and controls, taking into account relevant characteristics such as age, gender, and autism quotient. Our findings…

Extreme prematurity is known as a risk factor for autism spectrum disorder (ASD). However, the association between prematurity and ASD, for children born moderately and late preterm (MLPT) and those born early term (ET), is less established. This retrospective study aimed to characterize the phenotypic characteristics (i.e. behavioral profile and…

This study tested whether individuals with autism spectrum conditions (n = 23) show enhanced discrimination of acoustic differences that signal a linguistic contrast (i.e., /g/ versus /k/ as in "goat" and "coat") and whether they process such differences in a less categorical fashion as compared with 23 IQ-matched typically…

Data from the Autism Inpatient Collection was used to examine the relationship between problem behaviors and verbal ability, which have generally, though not universally, been highly associated. In a comparison of 169 minimally-verbal and 177 fluently-verbal 4 to 20-year-old psychiatric inpatients with ASD, the severity of self-injurious behavior,…

Few interventions exist for school-aged minimally verbal children with autism spectrum disorder (ASD). Even though play skills are associated with children's production of language, few studies have focused on play for minimally verbal children. Fifty-eight minimally verbal children with ASD received a naturalistic developmental behavioral…

Visual attention and active engagement during shared book reading are important for facilitating emergent literacy learning during the preschool years. Children on the autism spectrum often show difficulties in language and literacy development, yet research investigating potential indicators of shared book reading engagement, including visual…

People with autism spectrum disorder (ASD) exhibit comorbidity with anxiety. The aim of this study was the investigation of the perception of teachers on anxiety in school children with ASD. The Scale Teacher Response (SAS-TR) questionnaire was completed by 291 special education and 118 general education teachers, providing data on students in…

The two prior studies that have examined associations between the sibling constellation and theory of mind in autism spectrum disorder yielded discrepant findings. Thus, efforts to better understand the sibling-theory of mind link in autism spectrum disorder are necessary. This study examined a sample of prekindergarten- and kindergarten-aged…

The literature concerning sexuality in autism spectrum disorders (ASDs) is limited regarding inappropriate sexual behaviours and paraphilias and its relation to age, verbal ability, symptom severity, intellectual ability, or adaptive functioning. A cohort of 184 adolescents and young adults (ages 15-39 years) with ASD diagnosed in childhood,…

Formal thought disorder (FTD) is a disruption in the flow of thought and a common feature in psychotic disorders and autism spectrum disorder (ASD). Executive dysfunction has often been associated with FTD, yet for ASD convincing evidence is lacking. This study investigated FTD and three core executive functions in 50 young children and…
