Aim: The study aim was to culturally adapt and translate the M-CHAT-R/FTM into Northern…

A Delphi consensus methodology was used to adapt the Autism Diagnostic Interview--Revised for the assessment of deaf children with suspected autism spectrum disorder. Each Autism Diagnostic Interview--Revised item was considered by a panel of nine international experts in terms of relevance and acceptability. Modifications were proposed and agreed…

Our objective was to develop a measure of healthcare providers' self-efficacy in providing healthcare to autistic adults and to better understand their training needs. We used a community-based participatory research approach with academic researchers, autistic adults, supporters, and healthcare providers. We developed a one-page questionnaire…

We carried out a psychometric assessment of the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS-2) in fragile X syndrome (FXS), relative to clinician DSM5-based diagnosis of autism spectrum disorder (ASD) in FXS. This was followed by instrument revisions that included: removal of non-discriminating and/or low face…

Limited research has been done to explore parental perception of stigma. The present study developed the Parental Perceptions of Public Attitudes Scale to examine perceived stigma among Serbian parents of children with autism spectrum disorder (ASD) and children with physical disabilities (PD).

This study describes the development and psychometric evaluation of a new self-report measure of social cognition: the Theory of Mind Inventory:Self-Report--Adult (ToMI:SR-Adult). Adults with autism (or a suspicion of autism; n = 111) and typically developing adults (n = 109) completed a demographic questionnaire and the ToMI:SR-Adult online. Both…

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…

Although symptoms of autism are present early in life and early diagnosis can lead to better outcomes, there is a dearth of validated caregiver-report interviews designed for children under the age of 3 years.

It is important for all professionals who work with individuals who have ASD to have sufficient knowledge of the disorder. The development of ASD knowledge may occur during preservice training and/or through professional development. Currently, there is no "gold standard" measure of ASD knowledge. A study focusing on the development of a…

High rates of depressive disorders are reported among young people on the autism spectrum. This condition is generally assessed using measures validated for typically developing young people. Tools adapted to children on the autism spectrum are not tailored to detect Major Depressive Disorder, nor have they been used among samples with an…

Despite the dramatic rise in Autism Spectrum Disorder (ASD) prevalence, limited information is known about ASD knowledge of the general population. The Autism Spectrum Knowledge Scale, General Population version (ASKSG) was collaboratively constructed to create a measure of ASD knowledge specifically for the general population. The ASKSG is a…

Introduction: Current measures of restrictive and repetitive behavior (RRB) in people with autism focus on severity and intensity and, to some degree, the global interference of the behavior. In this study we developed the Social Impact of Repetitive Behavior Scale (SIRBS) to capture several different contexts in which repetitive behavior is…

This work presents the design and validation process for a tool to evaluate educational mobile applications for autistic learners. The project was developed in several stages. First, we reviewed and analysed the literature. Second, we conducted a Delphi study with experts (n=12) from different backgrounds (educational technology, accessibility,…
