Muharib, Reem; Alrasheed, Fahad; Ninci, Jennifer; Walker, Virginia L.; Voggt, Ashley P. – Journal of Autism and Developmental Disorders, 2019
Functional communication training (FCT) is an evidence-based practice used to mitigate challenging behavior by increasing functional communication skills. To increase the practicality and feasibility of FCT in natural settings, thinning schedules of reinforcement are typically programmed following FCT. In this review, we meta-analyzed 28 studies…

Ben-Sasson, Ayelet; Gal, Eynat; Fluss, Ronen; Katz-Zetler, Neta; Cermak, Sharon A. – Journal of Autism and Developmental Disorders, 2019
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…

Finnegan, Elizabeth; Accardo, Amy L. – Journal of Autism and Developmental Disorders, 2018
Although studies exist measuring the effectiveness of writing interventions for students with autism spectrum disorder (ASD), research assessing the writing skills for this group is sparse. The present study identified differences in the written expression of individuals with ASD compared to typically developing (TD) peers, using variables…

Association of congenital cytomegalovirus (CMV) infection with autism spectral disorder (ASD) has been suggested since 1980s. Despite the observed association, its role as a risk factor for ASD remains to be defined. In the present review, we systematically evaluated the available evidence associating congenital CMV infection with ASD using…

Lugo Marín, Jorge; Rodríguez-Franco, Montserrat Alviani; Mahtani Chugani, Vinita; Magán Maganto, María; Díez Villoria, Emiliano; Canal Bedia, Ricardo – Journal of Autism and Developmental Disorders, 2018
Since their separation as independent diagnostics, autism spectrum disorders (ASD) and schizophrenia spectrum disorders (SSD) have been conceptualized as mutually exclusive disorders. Similarities between both disorders can lead to misdiagnosis, especially when it comes to average-IQ adults who were not identified during childhood. The aim of this…

Wolstencroft, J.; Robinson, L.; Srinivasan, R.; Kerry, E.; Mandy, W.; Skuse, D. – Journal of Autism and Developmental Disorders, 2018
Group social skills interventions (GSSIs) are a commonly offered treatment for children with high functioning ASD. We critically evaluated GSSI randomised controlled trials for those aged 6-25 years. Our meta-analysis of outcomes emphasised internal validity, thus was restricted to trials that used the parent-report social responsiveness scale…

Lim, Yi Huey; Partridge, Katie; Girdler, Sonya; Morris, Susan L. – Journal of Autism and Developmental Disorders, 2017
Impairments in postural control affect the development of motor and social skills in individuals with autism spectrum disorder (ASD). This review compared the effect of different sensory conditions on static standing postural control between ASD and neurotypical individuals. Results from 19 studies indicated a large difference in postural control…

Landsiedel, Julia; Williams, David M.; Abbot-Smith, Kirsten – Journal of Autism and Developmental Disorders, 2017
Prospective memory (PM) is the ability to remember to carry out a planned intention at an appropriate moment in the future. Research on PM in ASD has produced mixed results. We aimed to establish the extent to which two types of PM (event-based/time-based) are impaired in ASD. In part 1, a meta-analysis of all existing studies indicates a large…

Saghazadeh, Amene; Rezaei, Nima – Journal of Autism and Developmental Disorders, 2017
Brain-derived neurotrophic factor (BDNF) plays an important role in activity-dependent synaptic plasticity. Altered blood BDNF levels have been frequently identified in people with autism spectrum disorders (ASD). There are however wide discrepancies in the evidence. Therefore, we performed the present systematic review and meta-analysis aimed at…

Olde Dubbelink, Linda M. E.; Geurts, Hilde M. – Journal of Autism and Developmental Disorders, 2017
Individuals with an autism spectrum disorder (ASD) are thought to encounter planning difficulties, but experimental research regarding the mastery of planning in ASD is inconsistent. By means of a meta-analysis of 50 planning studies with a combined sample size of 1755 individuals with and 1642 without ASD, we aim to determine whether planning…

Royston, R.; Howlin, P.; Waite, J.; Oliver, C. – Journal of Autism and Developmental Disorders, 2017
Individuals with specific genetic syndromes associated with intellectual disability (ID), such as Williams syndrome (WS), are at increased risk for developing anxiety disorders. A systematic literature review identified sixteen WS papers that could generate pooled prevalence estimates of anxiety disorders for WS. A meta-analysis compared these…

Li, Ya-Min; Ou, Jian-Jun; Liu, Li; Zhang, Dan; Zhao, Jing-Ping; Tang, Si-Yuan – Journal of Autism and Developmental Disorders, 2016
As the link between maternal obesity and risk of autism among offspring is unclear, the present study assessed this association. A systematic search of an electronic database was performed to identify observational studies that examined the association between maternal obesity and autism. The outcome measures were odds ratios comparing offspring…

Westwood, Heather; Eisler, Ivan; Mandy, William; Leppanen, Jenni; Treasure, Janet; Tchanturia, Kate – Journal of Autism and Developmental Disorders, 2016
Interest in the link between Autism Spectrum Disorder (ASD) and Anorexia Nervosa (AN) has led to estimates of the prevalence of autistic traits in AN. This systematic review and meta-analysis assessed the use of the Autism-Spectrum Quotient (AQ) or abbreviated version (AQ-10) to examine whether patients with AN have elevated levels of autistic…
