This meta-analysis updated evidence regarding sensory over-responsivity (SOR), under-responsivity (SUR) and seeking symptoms in individuals with autism spectrum disorders (ASDs) relative to typical controls and those with other conditions. Fifty-five questionnaire studies included 4606 individuals with ASD. Moderators tested were age, IQ, male…

Peñuelas-Calvo, Inmaculada; Sareen, Aditya; Sevilla-Llewellyn-Jones, Julia; Fernández-Berrocal, Pablo – Journal of Autism and Developmental Disorders, 2019
We conducted a meta-analysis of 18 studies to establish whether a relation exists between Reading the Mind in the Eye Test (RMET) performance and intelligence quotient (IQ) in individuals diagnosed with autism-spectrum disorders (ASD) and controls, taking into account relevant characteristics such as age, gender, and autism quotient. Our findings…

De Palma, Giuseppe; Catalani, Simona; Franco, Anna; Brighenti, Maurizio; Apostoli, Pietro – Journal of Autism and Developmental Disorders, 2012
A cross-sectional case-control study was carried out to evaluate the concentrations of metallic elements in the hair of 44 children with diagnosis of autism and 61 age-balanced controls. Unadjusted comparisons showed higher concentrations of molybdenum, lithium and selenium in autistic children. Logistic regression analysis confirmed the role of…

Barger, Brian D.; Campbell, Jonathan M.; McDonough, Jaimi D. – Journal of Autism and Developmental Disorders, 2013
Rates and onset of regression were meta-analyzed from 85 articles representing 29,035 participants with autism spectrum disorders (ASD). Overall prevalence rate for regression was 32.1, 95% CI [29.5, 34.8] occurring at mean of 1.78 years, 95% CI [1.67, 1.89]. Regression prevalence rates differed according to four types of regression: language…

Wang, Shin-Yi; Parrila, Rauno; Cui, Ying – Journal of Autism and Developmental Disorders, 2013
This meta-analysis used hierarchical linear modeling to examine 115 single-case studies with 343 participants that examined the effectiveness of social skills interventions for individuals with autism spectrum disorder (ASD). The average effect size of the included studies was 1.40 (SD = 0.43, 95% CL = 1.32-1.48, N = 115). In the further, several…
