Garcia-Villamisar, D.; Moore, D.; Garcia-Martínez, M. – Journal of Autism and Developmental Disorders, 2019
Research on pain in autism spectrum disorder (ASD) is in its infancy, with almost nothing known about how individual differences may predicting pain response in ASD. In the present study, 45 adults (28 male, age 22-48 years) with diagnoses of autism and intellectual delay were observed during vaccination or dental cleaning and their pain…

Haraguchi, Hideyuki; Stickley, Andrew; Saito, Aya; Takahashi, Hidetoshi; Kamio, Yoko – Journal of Autism and Developmental Disorders, 2019
Little is known about the across time stability of autistic traits during the transition period from preschool to school age in the general population. The current study compared autistic traits assessed by a mother-reported quantitative measure, the Social Responsiveness Scale, at age 5 and 8 years and examined the intraclass correlation…

López Pérez, David; Kennedy, Daniel P.; Tomalski, Przemyslaw; Bölte, Sven; D'Onofrio, Brian; Falck-Ytter, Terje – Journal of Autism and Developmental Disorders, 2019
Autism spectrum disorder (ASD) is commonly conceived as the extreme end of a continuum. Research suggests that autistic individuals outperform typically developing controls in visual search. Thus, enhanced visual search may represent an adaptive trait associated with ASD. Here, using a large general population sample (N = 608, aged 9-14 years), we…

Kašcelan, Draško; Katsos, Napoleon; Gibson, Jenny L. – Journal of Autism and Developmental Disorders, 2019
Some evidence suggests that bilingualism improves communication and cognitive skills which are often impaired in autism. However, diagnosing autism in bilinguals may suffer a cultural bias, which can affect the investigation of bilingualism and autism. Therefore, the current study investigates relations between autistic-like traits (ALTs) and…

Houghton, Richard; Monz, Brigitta; Law, Kiely; Loss, Georg; Le Scouiller, Stephanie; de Vries, Frank; Willgoss, Tom – Journal of Autism and Developmental Disorders, 2019
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…

Johnston, Kate; Murray, Kim; Spain, Debbie; Walker, Ian; Russell, Ailsa – Journal of Autism and Developmental Disorders, 2019
Studies of executive function (EF) in autism spectrum disorder (ASD) have reported mixed findings. Possible confounds include EF domain assessed and co-occurring neurodevelopmental diagnoses. EF task performance across multiple domains and everyday function of autistic adults (n = 110) was significantly different to age- and IQ-matched controls (n…

Lundin, Andreas; Kosidou, Kyriaki; Dalman, Christina – Journal of Autism and Developmental Disorders, 2019
Background: The autism-spectrum quotient scale was developed to study autism as a spectrum. Few studies have examined the psychometric properties of the 10 item AQ (AQ-10). We examine the AQ-10 measurement ability and convergent validity in a population health survey (n = 44,722). Methods: The item severity and item discrimination was assessed…

Prior studies of sex-based differences in autism spectrum disorder (ASD) have yielded mixed findings. This study examined ASD symptom severity and functional correlates in a sample of 34 high-functioning females with ASD (HFASD; M age = 8.93; M IQ = 104.64) compared to 34 matched males (M age = 8.96; M IQ = 104.44) using the Social Responsiveness…

Gomez, Rapson; Stavropoulos, Vasileios; Vance, Alasdair – Journal of Autism and Developmental Disorders, 2019
Confirmatory factor analysis (CFA) and exploratory and factor analysis (EFA) aimed to determine the optimum Autism Spectrum Quotient--Children (AQ-Child) model. Initial CFA of parent ratings of the AQ-Child for 404 clinic-referred children with ADHD, aged between 4 and 11 years, revealed mixed/moderate support for the implied AQ-Child five-factor…

Franke, Kathleen Blackburn; Hills, Kimberly; Huebner, E. Scott; Flory, Kate – Journal of Autism and Developmental Disorders, 2019
We provided evidence regarding the reliability and validity of measures of assets and life satisfaction (LS) for adolescents with autism spectrum disorder (ASD). We identified levels of LS within this population, compared these levels to those of typically developing adolescents, and described the relation between assets and LS. Forty-six…

Matheis, Maya; Matson, Johnny L.; Hong, Esther; Cervantes, Paige E. – Journal of Autism and Developmental Disorders, 2019
A growing body of research suggests that symptoms of autism spectrum disorder (ASD) may present differently in males and females. This study examined gender differences in ASD symptoms and developmental functioning, using the "Baby and Infant Screen for Children with aUtism Traits, Part 1" (BISCUIT-Part 1) and the "Battelle…

Stronach, Sheri; Wiegand, Sarah; Mentz, Emily – Journal of Autism and Developmental Disorders, 2019
Increased public understanding of autism may lead to better access to services and participation in the community for individuals with autism. The goal of this study was to explore autism understanding and stigma among university students, and general community members recruited at a state fair. Participants between 18 and 79 years of age (n =…

Cohen, Ira L.; Flory, Michael J. – Journal of Autism and Developmental Disorders, 2019
A recent cross-sectional analysis of PDD Behavior Inventory (PDDBI) data, analyzed with a classification and regression tree algorithm, yielded a decision tree (the Autism Spectrum Disorder-Decision Tree or ASD-DT) that detected three behaviorally distinct ASD subgroups: minimally verbal, verbal, and atypical. These subgroups differed in PDDBI…

The Psychoeducational Profile 3rd Edition (PEP-3) is a comprehensive assessment tool designed for children with autism spectrum disorder (ASD). Although its original English version has been validated, few validation studies have been conducted on translated versions including Chinese ones. Based on 554 Chinese children with ASD and 311 typically…

Barger, Brian; Moody, Eric J.; Ledbetter, Caroline; D'Abreu, Larissa; Hepburn, Susan; Rosenberg, Steven A. – Journal of Autism and Developmental Disorders, 2019
The majority of studies of temperament in children with autism spectrum disorder (ASD) use scales normed on typical populations. The present study examined a widely used measure of temperament, the Behavioral Style Questionnaire (McDevitt and Carey in Behavioral Styles Questionnaire, Behavioral-Developmental Initiatives Scottsdale, AZ, 1975) to…
