Sasson, Noah J.; Bottema-Beutel, Kristen – Autism: The International Journal of Research and Practice, 2022
Studies of autistic traits in the general population are becoming increasingly prevalent. In this letter to the editor, we caution researchers against framing and interpreting studies of autistic traits in the general population as extending to autism and implore them to be clear about when their study sample does and does not include autistic…

Godoy-Giménez, M.; González-Rodríguez, A.; Cañadas, F.; Estévez, A. F.; Sayans-Jiménez, P. – Journal of Autism and Developmental Disorders, 2022
Although, the operationalization of the autism spectrum disorder has been updated around two domains, the broad autism phenotype (BAP) one has not. Additionally, the items of the three common BAP measures, the Broad Autism Phenotype Questionnaire (BAPQ), the Autism Quotient, and the Social Responsiveness Scale (SRS), remain organized around a…

Zhu, Jiang; Hua, Xueying; Yang, Ting; Guo, Min; Li, Qiu; Xiao, Lu; Li, Ling; Chen, Jie; Li, Tingyu – Journal of Autism and Developmental Disorders, 2022
Metabolic disturbance may be implicated in the pathogenesis of autism. This study aimed to investigate the gut metabolomic profiles of autistic children and to analyze potential interaction between gut metabolites with autistic symptoms and neurodevelopment levels. We involved 120 autistic and 60 neurotypical children. Autistic symptoms and…

Schulz, S. E.; Stevenson, R. A. – Journal of Autism and Developmental Disorders, 2022
Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

Perry, Ella; Mandy, William; Hull, Laura; Cage, Eilidh – Journal of Autism and Developmental Disorders, 2022
Camouflaging refers to strategies used by autistic people to mask or hide social difficulties. The current study draws on Social Identity Theory to examine the relationship between camouflaging and autism-related stigma, testing the hypothesis that camouflaging represents an individualistic strategy in response to stigma. Two hundred and…

Karagözlü, Selen; Dalgiç, Buket; Iseri, Elvan – Journal of Autism and Developmental Disorders, 2022
To evaluate the relationship between the severity of autism, severity of gastrointestinal symptoms and serum zonulin levels as a marker of increased intestinal permeability in children. Serum zonulin levels were determined in 56 children with ASDs and 55 healthy children. The severity of gastrointestinal symptoms and ASD symptoms was assessed with…

Tubío-Fungueiriño, María; Cruz, Sara; Sampaio, Adriana; Carracedo, Angel; Fernández-Prieto, Montse – Journal of Autism and Developmental Disorders, 2021
Autism spectrum disorder (ASD) is a neurodevelopmental disorder with increasing prevalence, and a male-to-female ratio of 4:1. Research has been suggesting that discrepancy in prevalence may be due to the fact that females camouflage their symptoms. In this study, we aimed to systematically review evidence on the camouflage effect in females with…

Lai, Meng-Chuan – Autism: The International Journal of Research and Practice, 2022
The clinical diagnostic process for autism is complex, especially because of the high co-occurrence with other neurodevelopmental and mental health conditions (Gillberg, 2010; Lai et al., 2019). Diagnosis is more complicated in youth and adults than in younger children because life experience and development affect presentation. In particular, it…

Li, Jinglun; Chen, Xiu; Zheng, Ruwen; Chen, Ai; Zhou, Yan; Ruan, Jianghai – Journal of Autism and Developmental Disorders, 2022
Autism spectrum disorder (ASD) is a neurodevelopmental disorder. The associations between the cerebellum and clinical traits remain unclear. We performed amplitude of low-frequency fluctuation (ALFF) analysis to explore the associations between spontaneous brain activity and clinical traits. 361 juvenile ASD patients were included from the ABIDEII…

Law, Mei L.; Singh, Jatinder; Mastroianni, Mathilde; Santosh, Paramala – Journal of Autism and Developmental Disorders, 2022
Prodromal symptoms of Autism Spectrum Disorder (ASD) have been detected within the first year of life. This review evaluated evidence from randomized controlled trials (RCTs) of parent-mediated interventions for infants under 24 months who are at risk for ASD. Electronic databases, including grey literature, were searched up till November 2019.…

Turbett, Kaitlyn; Jeffery, Linda; Bell, Jason; Burton, Jessamy; Palermo, Romina – Journal of Autism and Developmental Disorders, 2022
Face recognition difficulties are common in autism and could be a consequence of perceptual atypicalities that disrupt the ability to integrate current and prior information. We tested this theory by measuring the strength of serial dependence for faces (i.e. how likely is it that current perception of a face is biased towards a previously seen…

Diefenbach, Gretchen J.; Stevens, Kimberly T.; Dunlap, Amanda; Nicholson, Alycia M.; Grella, Olivia N.; Pearlson, Godfrey; Assaf, Michal – Journal of Autism and Developmental Disorders, 2022
Cognitive reappraisal is associated with reduced emotional distress; however, little is known about the nature of this relationship in autism. This study tested whether autistic traits moderate reappraisal success (i.e., the negative correlation between reappraisal use and emotional symptom severity). Emotional symptoms were assessed using…

Aykan, Simge; Puglia, Meghan H.; Kalaycioglu, Canan; Pelphrey, Kevin A.; Tuncali, Timur; Nalçaci, Erhan – Journal of Autism and Developmental Disorders, 2022
Our aim was to use theta coherence as a quantitative trait to investigate the relation of the polymorphisms in "NKCC1" (rs3087889) and "KCC2" (rs9074) channel protein genes to autistic traits (AQ) in neurotypicals. Coherence values for candidate connection regions were calculated from eyes-closed resting EEGs in two independent…

Lee, Inn-Chi; Wang, Yu-Hsun; Chiou, Jeng-Yuan; Wei, James Cheng-Chung – Journal of Autism and Developmental Disorders, 2022
We analyzed claims data from the Taiwan National Health Insurance database, which contains data of 23.5 million Taiwan residents. We included children born after January 1, 2000 who had received a diagnosis of autism spectrum disorders (ASD). Patients who were not diagnosed with ASD were included in the control group. The ASD prevalence was 517 in…

Neonatal jaundice has been suggested as a perinatal risk factor for autism spectrum disorder (ASD). We examined UGT1A1 polymorphisms to assess the potential of neonatal jaundice as a risk factor for ASD in children by using DNA extracted from preserved umbilical cord. In total, 79 children with ASD were genotyped for "UGT1A1*28"…
