The Aut-Eat Questionnaire (AEQ) provides a novel and comprehensive assessment of eating problems and patterns in children with ASD. To establish the internal consistency and discriminant validity of the AEQ, parents of children with ASD (n = 105, M[subscript age] = 40.85, SD = 15.67 months) or typical development (TD; n = 98, M[subscript age] =…

Feeding problems are prevalent in children with ASD. We investigated whether the Montreal Children's Hospital Feeding Scale (MCH-FS, Ramsay et al. in Pediatrics and Child Health 16:147-151, 2011) can be used for young children with ASD. Participants (1-6 years) were selected from a clinical ASD sample (n = 80) and a general population sample (n =…

Valid and reliable tools to measure mental health are a key requirement to developing a robust evidence base on mental health difficulties and autism. There are several reasons why mental health measures developed for the neurotypical population may not be valid and reliable when used with autistic adults. Using data collected from a national…

Despite the advances on the assessment of quality of life, this concept is barely studied and is riddled with important limitations for those with autism spectrum disorder (ASD). This article is aimed at validating a questionnaire to assess quality of life of children with ASD and intellectual disability (ID). Based on the KidsLife Scale, geared…

Diagnosis of Autism Spectrum Conditions (ASC) can be an extended procedure since ASC tend to both vary greatly across individual symptoms and diagnostic pathways with serious challenges to opportune access and diagnosis in low resource settings. We adapted the Q-CHAT-25 for use in a routine health check-ups programme at Chilean primary health…

The objective of this study was to adapt and validate the abbreviated version of the "Autism-Spectrum Quotient" (AQ-Short) in a sample of Spanish native adults. A total of 46 individuals with ASD, 41 ASD-relatives, 17 patients with schizophrenia spectrum disorders and 190 non-clinical adults were administered the Spanish version of the…

The Participation and Sensory Environment Questionnaire: Home Scales (P-SEQ): Home Scales is a parent report tool designed to assess the impact of the sensory environment on participation in daily activities in the home of children with and without autism spectrum disorder. A cross-sectional study was completed to determine internal consistency,…

Accurately diagnosing autism spectrum disorders in adulthood can be challenging. Structured questionnaires and diagnostic measures are frequently used to assist case recognition and diagnosis. This study reviewed research evidence on structured questionnaires and diagnostic measures published since the National Institute for Health and Care…

Negatives attitudes toward children with autism are an important barrier to school inclusion. Despite the increasing amount of research, no psychometrically sound scale reliably measures these attitudes in young students. Our aim was to develop and validate a tool (Children's Attitudes Toward Autism Questionnaire) to evaluate attitudes (three…

Validated screening and diagnostic tools for autism spectrum disorder for use in Arabic-speaking individuals are scarce. This study validated the Arabic version of the Social Communication Questionnaire. The total study sample included 206 children with autism spectrum disorder and 206 typically developing children (73.8% male; mean age: 8.5…

Pathological ("extreme") demand avoidance (PDA) involves obsessively avoiding routine demands and extreme emotional variability. It is clinically linked to autism spectrum disorder (ASD). The observer-rated EDA Questionnaire (EDA-Q) for children was adapted as an adult self-report (EDA-QA), and tested in relation to personality and the…

The Questionnaire for Autism Spectrum Conditions (Q-ASC) was developed by Attwood et al. (2011) to identify gender-sensitive profiles of autism symptomatology; prioritise and adjust the direction of clinical interventions; and support positive psychosocial outcomes and prognosis into adulthood. The current research piloted the Q-ASC with parents…

Background: Both parent-report and clinician-administered autism spectrum disorder (ASD) screening instruments are important to accurately inform ASD risk ascertainment. The aim of this study was to adapt a clinician-administered ASD screening instrument, the Autistic Behavioural Indicators Instrument (ABII), as a parent questionnaire equivalent…

The Pervasive Developmental Disorder Behavior Inventory is a questionnaire designed to aid in the diagnosis of pervasive developmental disorders or autism spectrum disorders. The Pervasive Developmental Disorder Behavior Inventory assesses adaptive and maladaptive behaviors associated with pervasive developmental disorders and provides an…

Schools have an obligation to assess the literacy skills of their students, and the provision of reading instruction to students includes the ability to measure progress in this area. However, the design of reading tests includes the ability not only to read words, but also the ability to verbalise them. This presents a particular challenge for…
