Lauren Gardner; Callie Gilchrest; Jonathan M. Campbell – Journal of Autism and Developmental Disorders, 2024
The diagnostic criteria for autism spectrum disorder in the DSM-5-TR features the option to designate levels of support for social communication (SC) and restricted, repetitive behaviors (RRB). These levels are conceptual in nature, but research indicates standardized assessment outcomes correspond with clinician-assigned levels of support. The…

Irene Polo-Blanco; Paula Suárez-Pinilla; Juncal Goñi-Cervera; Marta Suárez-Pinilla; Beatriz Payá – Journal of Autism and Developmental Disorders, 2024
This study examines relationships between mathematical problem-solving performance (in terms of strategies used and accuracy) and the main cognitive domains associated with mathematical learning (i.e. executive functions, verbal comprehension and social perception) of children with and without autism spectrum disorder (ASD and non-ASD resp.). The…

3q29 deletion syndrome (3q29del) is associated with neuropsychiatric and neurodevelopmental phenotypes. We previously reported that graphomotor weakness is present in up to 78% of individuals with 3q29del. We have now explored nuances of the graphomotor phenotype and its association with other comorbidities in this population. Participants were…

Berloco Bianca; Guerrera Silvia; Fucà Elisa; Menghini Deny; Valeri Giovanni; Nobili Lino; Vicari Stefano – Journal of Autism and Developmental Disorders, 2024
Insomnia is one of the most common co-occurring disorders in children with autism spectrum disorder (ASD). The purpose of this cross-sectional cohort study of 270 children with ASD was to assess the prevalence of insomnia using the Pediatric Sleep Clinical Global Impression Scale and to correlate sleep problems with cognitive level, adaptive…

Calhoun, Susan L.; Pearl, Amanda M.; Fernandez-Mendoza, Julio; Durica, Krina C.; Mayes, Susan D.; Murray, Michael J. – Journal of Autism and Developmental Disorders, 2020
Sleep disturbances (SD) are prevalent in individuals diagnosed with Autism Spectrum Disorder (ASD). Less is known about the effects of SD on cognition and learning in adolescents with high-functioning ASD (HF-ASD). Adolescents with HF-ASD (N = 96) were evaluated for the relationships of SD to working memory and learning problems. Results found SD…

Galligan, Megan Ledoux; Heyman, Michelle; Bolourian, Yasamin; Stavropoulos, Katherine; Blacher, Jan – Journal of Autism and Developmental Disorders, 2022
Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the "Autism Diagnostic Observation Schedule--Second Edition," includes three items ("E-codes") for EBPs that are frequently associated…

Piwowarczyk, Anna; Horvath, Andrea; Pisula, Ewa; Kawa, Rafal; Szajewska, Hania – Journal of Autism and Developmental Disorders, 2020
To determine whether a gluten-free diet (GFD) compared with a gluten-containing diet (GD) influences functioning of children with autism spectrum disorders (ASD), we performed a randomized, controlled, single-blinded trial. Sixty-six children (36-69 months) with ASD, within the normal IQ (> 70) range, who had been on a GFD for at least 8 weeks…

Milgramm, Anna; Christodulu, Kristin V.; Rinaldi, Melissa L. – Journal of Autism and Developmental Disorders, 2021
The rising prevalence of autism spectrum disorder (ASD) necessitates a greater understanding of the academic experience of diagnosed children. The present study investigates several predictors of teacher-reported academic competence among a sample of elementary school children. All children in the sample were referred for an ASD evaluation and…

Correlates of Feeding Difficulties among Children with Autism Spectrum Disorder: A Systematic Review
Page, Shayleigh Dickson; Souders, Margaret C.; Kral, Tanja V. E.; Chao, Ariana M.; Pinto-Martin, Jennifer – Journal of Autism and Developmental Disorders, 2022
Feeding difficulties related to selective intake, or eating a limited variety of foods, are very common in children with autism spectrum disorder (ASD). A systematic search of PubMed, Embase, PsycInfo, and CINAHL identified 29 studies that evaluated eight correlates: age, ASD symptoms and severity, cognitive and adaptive skills, sensory processing…

Bullen, Jennifer C.; Swain Lerro, Lindsay; Zajic, Matthew; McIntyre, Nancy; Mundy, Peter – Journal of Autism and Developmental Disorders, 2020
This study examined mathematics achievement in school-aged children with autism spectrum disorder (ASD), symptoms of attention-deficit/hyperactivity disorder (ADHD), or typical development (TD) over a 30-month period and the associations between cognitive and reading abilities with mathematics achievement in children with ASD. Seventy-seven…

H.; Pasco, Greg; Pickles, Andrew; Tucker, Leslie; Volein, Agnes – Journal of Autism and Developmental Disorders, 2018
Cognitive and adaptive behaviour abilities early in life provide important clinical prognostic information. We examined stability of such skills in children at high familial risk for ASD who either met diagnostic criteria for ASD at age 7 years (HR-ASD, n = 15) or did not (HR-non-ASD, n = 24) and low-risk control children (LR, n = 37),…

Booules-Katri, Tereza-Maria; Pedreño, Carla; Navarro, Jose-Blás; Pamias, Montserrat; Obiols, Jordi E. – Journal of Autism and Developmental Disorders, 2019
The similarities between high functioning autism (HFA) and schizotypal-schizoid personality disorder (SSPD) in terms of social cognition and interpersonal deficits may lead to confusion in symptom interpretation, and consequently result in misdiagnosis. Thus, this study aims to investigate differences in mentalizing with particular interest on the…

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…

Brennan, Laura; Barton, Marianne; Chen, Chi-Ming; Green, James; Fein, Deborah – Journal of Autism and Developmental Disorders, 2015
Hierarchical cluster analyses were used to detect three subgroups in a sample of children with pervasive developmental disorder--not otherwise specified (PDD-NOS) evaluated at ages 2 and 4. At age 2, Cluster 1 demonstrated few autism symptoms and high cognitive scores; 60% no longer met criteria for PDD at 4. Cluster 2 exhibited more autism…

Lawson, Lauren P.; Joshi, Rucha; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2018
Relatively few studies have examined gender differences in infants and toddlers, and most focus on clinically referred samples or high-risk infant cohorts. The current study aimed to examine gender differences in early autism manifestations and cognitive development in a community-ascertained sample. In total, 46 males and 21 females with ASD were…
