Purpose: Predictions are complex, multisensory, and dynamic processes involving real-time adjustments based on environmental inputs. Disruptions to prediction abilities have been proposed to underlie characteristics associated with autism. While there is substantial empirical literature related to prediction, the field lacks a self-assessment…

The Adult Autism Quotient (AQ), the Empathy Quotient (EQ) and the Relative's Questionnaire (RQ) were used as part of the Adult Asperger's Assessment (AAA) by a diagnostic service for adults without an intellectual disability with suspected autism spectrum disorder (ASD). This service is part of the National Health Service (NHS) in England. Little…

Purpose: Autistic camouflaging is a collection of strategies used to hide autistic characteristics. It can have serious consequences on autistic people's mental health and needs to be addressed and measured in clinical practice. The purpose of this study is to evaluate the psychometric properties of the French adaptation of the Camouflaging…

Purpose: Wellbeing refers to a person's overall happiness and satisfaction with life. Wellbeing for people with Intellectual and Developmental Disabilities (I/DD) and their families is historically significantly lower compared to the general population. It is important in the context of behavioral health treatment to not only measure the…

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] =…

Although motor problems are highly prevalent in children with autism spectrum disorder (ASD), they remain underdiagnosed. Questionnaire-based screening for motor problems could optimize current clinical practice. This study aimed to examine the psychometric properties of the developmental coordination disorder questionnaire (DCDQ) to screen for…

The aim of this study was to examine the reliability and validity of the Turkish version of the AFEQ for Turkish parents of children with ASD. The Turkish-translated version of the AFEQ was administered to 241 parents of children aged 2-12 years with ASD to examine the construct validity and internal consistencies. Parents completed the Autism…

Tools to measure autism knowledge are needed to assess levels of understanding within particular groups of people and to evaluate whether awareness-raising campaigns or interventions lead to improvements in understanding. Several such measures are in circulation, but, to our knowledge, there are no psychometrically-validated questionnaires that…

We explored the appropriateness and measurement properties of a suicidality assessment tool (SBQ-R) developed for the general population, in autistic adults--a high risk group for suicide. 188 autistic adults and 183 general population adults completed the tool online, and a sub-sample (n = 15) were interviewed while completing the tool.…

Despite the high prevalence of depression and other mental illnesses in autistic adults, screening instruments such as the Patient Health Questionnaire (PHQ-9) have not been specifically validated in an autistic sample. Using data from two Autism CRC longitudinal studies (n = 581), confirmatory factor analysis supported the two-factor model…

Impairments in structural language and pragmatics are well recognized in different neurodevelopmental disorders, yet in clinical work the discrimination of children with various language difficulties into different diagnostic profile is still a major challenge. Using the CCC-2 questionnaire this study assesses and compares language competences in…

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 Autism impact measure (AIM) is a caregiver-reported questionnaire assessing autism symptom frequency and impact in children, previously shown to have good test-retest reliability, convergent validity and structural validity. This study extended previous work by exploring the AIM's ability to discriminate between 'known-groups' of children, and…

This study aims to translate the Brief Autism Mealtime Behaviour Inventory (BAMBI) questionnaire to Brazilian Portuguese, in order to provide a tool to be used in clinic routine that encourages the evaluation of the feeding behaviour of patients with Autism Spectrum Disorder (ASD). The final sample contained 410 participants, the mean age was 9.58…

In this study the Autism Mental Status Exam (AMSE) was validated towards ICD-10 Autism Spectrum Diagnoses (ASD) based on an interview with the Diagnostic Interview for Social and Communication Disorders (DISCO-11) with parent(s)/caregiver(s) in a group of 124 children referred for assessment to a clinical assessment unit for pre-school children.…
