The SPARK cohort was established to facilitate recruitment in studies of large numbers of participants with autism spectrum disorder (ASD). Online registration requires participants to have received a lifetime professional diagnosis by health or school providers although diagnoses are not independently verified. This study was set to examine the…

For autism spectrum disorder (ASD) in adults there are several diagnostic instruments available with a need for consideration of the psychometric properties. This study aimed to conduct a first psychometric evaluation of a new diagnostic ASD instrument, the NIDA (Dutch Interview for Diagnostic assessment of ASD in adults) in 90 adult males without…

To examine reliability and validity of the new Social Motor Function Classification System for Children with Autism Spectrum Disorders (SMFCS-ASD). The SMFCS-ASD reliability was examined on 25 children (62.4 months SD 7.8) with ASD among six physical therapists. The validity study involved 1001 children (57.0 months, SD 9.9) with ASD using the…

Educators play an important role in supporting and monitoring social skills development for children with ASD, but the tools used by educators are often tedious, lack suitable…

To identify valid measures of vocal development in young children with autism spectrum disorder in the early stages of language learning, we evaluated the convergent validity, divergent validity, and sensitivity to change (across 12 months) of two measures of vocal communication and two measures of vocal complexity through conventional coding of…

Background: Here, I examine the status of 'learning disability' as a basic concept. This kind of questioning may be thought a task for philosophy, or at least for 'theory' or 'disability studies'. Materials and methods: I identify history instead as a discipline well placed to reveal the category errors that surround the concept. Results: These…

The actions and feelings questionnaire (AFQ) provides a short, self-report measure of how well someone uses and understands visual communicative signals such as gestures. The objective of this study was to translate and cross-culturally adapt the AFQ into Dutch (AFQ-NL) and validate this new version in neurotypical and autistic populations.…

Many autism-focused early intervention (EI) models have not yet been adopted by community-based providers in rural settings due to fit and feasibility when working within the Part C model. Family Implemented TEACCH for Toddlers (FITT, based on the University of North Carolina TEACCH Autism Program) is a research-based, Part-C compatible, EI model…

The aim of this study was to assess the social validity and document the implementation of a psychoeducational program designed to support parents after their child's diagnosis, from both parents' and professionals' perspectives. A complete version (five workshops and five individual follow-ups) and a shortened version (five workshops only) of the…

Resilience is an increasingly popular concept in literature as a protective factor against mental ill-health. While elevated rates of anxiety and mood disorders occur in adults on the autism spectrum, there is a gap in literature investigating the application of resilience to this population. This brief report examined the factor structure and…

Sensory sensitivity peculiarities represent an important characteristic of Autism Spectrum Disorders (ASD). We first validated a French language version of the Glasgow Sensory Questionnaire (GSQ) (Robertson and Simmons in "J Autism Dev Disord" 43(4):775-784, 2013). The GSQ score was strongly positively correlated with the Autism-Spectrum…

The validity of the Language ENvironment Analysis (LENA) System was evaluated for Dutch. 216 5-min samples (six samples per age per child) were selected from daylong recordings at 5, 10 and 14 months of age of native Dutch-speaking younger siblings of children with autism spectrum disorder (N=6) and of typically developing children (N=6). Two…

Psychiatric disorders in individuals with co-occurring autism spectrum disorders (ASD) and intellectual disability (ID) are common, but diagnosis presents many challenges. The Psychopathology in Autism checklist (PAC) is among the very few instruments specifically developed for this group of individuals. The psychometric properties of the PAC…
