There is limited literature examining the adaptive functioning of adolescents with autism spectrum disorder (ASD). This study aimed to (a) document Vineland Adaptive Behavior Scales (VABS-3) and Adaptive Behavior Assessment System (ABAS-3) adaptive behavior profiles of adolescents with ASD; (b) examine the comparability of the two measures; and…

This research determined the predictors of the adaptive behaviour of children with autism who are enrolled in special education centres using a descriptive correlational design. There were 40 children with autism whose adaptive behaviour was assessed in terms of their communication, daily living, social and motor skills using the modified Vineland…

We examined the correlation between interviewer-administered Vineland Adaptive Behavior Scale II (VABS-II) and the parent-rated Adaptive Behavior Assessment System II (ABAS-II) questionnaire in 352 participants (ages 1.5-20.8 years) with autism spectrum disorder (ASD) to determine if ABAS could be used as a screen to reduce the number of VABS…

Young students with ASD have instructional needs in social, communication, and learning skills that should be reflected in their Individualized Education Program (IEP). Research suggests that many of these goal areas present a challenge for special educators because of problems with measurability. The current study utilized an idiographic approach…

Although 70% of autistic children and young people meet criteria for co-occurring psychiatric conditions, there are few screening measures specifically for autistic individuals. We describe the development and validation of the Assessment of Concerning Behavior (ACB), an instrument co-developed with the autistic community to assess mental health…

The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for…

Controlled studies examining canine therapy in autism spectrum disorder are scarce. This study examined the effectiveness of a "Dog Training Intervention" on adaptive skills, autism severity, and anxiety using a controlled crossover design. Seventy-three participants diagnosed with autism spectrum disorder (M[subscript age] = 4:10 ± 1:0)…

This individual participant data meta-analysis is the most intensive possible evaluation of the effectiveness of early intensive applied behaviour analysis-based interventions for pre-school autistic children compared with treatment as usual/eclectic interventions. Data from 491 participants (originally collected in 10 studies) were included.…

We used parent-report data from a prospective longitudinal study to better understand the early strengths in written skills often observed in preschoolers on the spectrum. Consistent with previous research, children demonstrated relative strengths in standardized written communication compared to spoken communication scores on the VABS-II. We…

Restricted repetitive behaviors (RRBs) are a core feature of autism spectrum disorders (ASD) and further occur in intellectual disability (ID), mental disorders (MD), and in typically developed people (TD). There is a need of a valid and reliable measure to record RRBs as transdiagnostic symptom, which captures RRBs heterogeneity and evaluates…

The Early Start Denver Model (ESDM) is a promising early intervention for promoting improved social, cognitive, and communication outcomes for young children with autism spectrum disorder (ASD). However, most studies evaluating group-based delivery of this program have used 15-25 h per week of intervention in specialized ESDM preschools with low…

The study refers to the social aspect of Autism Spectrum Disorder (ASD) and focuses on pro-social behaviour that has a positive effect on social adaptability. The first goal of the study was to determine whether there is a gap in prosocial-behaviour between children with High-Functioning ASD (HFASD) and children with typical-development; and…

The effects of environmental factors [including Socio-Economic Status, Cultural Capital, and Social Capital (Socio-Cultural Level) of both parents] on the Vineland-II adaptive behavior dimensions of toddlers with autism spectrum disorder (ASD), in addition to individual factors, was investigated in 148 Italian toddlers (82% males), aged 18 to…

Recent studies of autism diagnosis in New Zealand have revealed inconsistent implementation of best practice standards in autism assessment and high rates of parental dissatisfaction with the diagnostic process. These findings have arisen despite the development and dissemination of the New Zealand Autism Spectrum Disorder Guideline (the…

The use of mobile devices has become a major medium of leisure engagement for the general population. However, individuals with intellectual disabilities (ID) experience disparities in technology access, which may limit their engagement in mobile device-based leisure. Little research has examined procedures for teaching individuals with ID to…
