We assessed the reliability and validity of the Turkish version of the autism spectrum quotient (AQ)-adolescent. Three assessment groups of adolescents, aged 11-18, were: 80 with Asperger syndrome/high-functioning autism (AS/HFA), 71 with other psychiatric disorders (PDs; 35 major depression, 18 obsessive-compulsive disorder, 18 social phobia),…

Background: In recent reviews of autism spectrum disorder screening tools, the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/FTM) has been recommended for use in lower middle-income countries to promote earlier identification. 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). The convenience sample consisted of 82 participants.…

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…

While autism spectrum disorder screening tools provide a useful resource for practitioners, the reality is they are underused. The justifications often provided include the time required for administration and the training involved. A brief tool with good psychometric properties that require minimal training is required. This study examined the…

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. We developed the Toddler Autism Symptom Inventory, a semi-structured interview designed to assess the presence and absence of skills and…

Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure--WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive…

There is currently a gap in available assessments for evaluating school readiness in children with Autism Spectrum Disorder (ASD). The Kindergarten Readiness Inventory (K-READI) is a non-standardized screener for basic kindergarten readiness skills of children with autism. The K-READI includes five subscales to assess overall school readiness,…

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…
