The impact of the pandemic is being very significant psychologically, especially for people who were already vulnerable in these aspects, such as adults with Autism Spectrum Disorders (ASD) and Intellectual Disability (ID). A longitudinal analysis of motor aspects such as balance and gait, executive functions in daily life, severity of symptoms…

There is uncertainty among researchers and clinicians about how to best measure autism spectrum dimensional traits in adults. In a sample of adults with high levels of autism spectrum traits and without intellectual disability (probands, n = 103) and their family members (n = 96), we sought to compare self vs. informant reports of autism…

Since the retina shares its embryological origin with the central nervous system, optical coherence tomography (OCT), an imaging technique frequently employed in ophthalmology to analyze the macula and intraretinal layer thicknesses and volumes, has recently become increasingly important in psychiatric research. We examined 34 autistic and 31…

Carson, Tana B.; Valente, Matthew J.; Wilkes, Bradley J.; Richard, Lynne – Journal of Autism and Developmental Disorders, 2022
Auditory sensory over-responsivity (aSOR) is a frequently reported sensory feature of autism spectrum disorders (ASD); however, there is little consensus regarding its prevalence and severity. This cross-sectional study uses secondary data from the Autism Diagnostic Interview-Revised (ADI-R; Item 72: "undue sensitivity to noise") housed…

Cohen, Ira L.; Tsiouris, John A. – Journal of Autism and Developmental Disorders, 2020
Aggressive behaviors in those with intellectual disability (ID) and autism (ASD) have been linked to a variety of factors including ID level, age, sex, psychiatric disorders, and medical conditions but these factors have not been studied, in large samples, in terms of how they affect the stimuli that trigger aggression. In this survey of 2243…

Uljarevic, Mirko; Hedley, Darren; Rose-Foley, Kitty; Magiati, Iliana; Cai, Ru Ying; Dissanayake, Cheryl; Richdale, Amanda; Trollor, Julian – Journal of Autism and Developmental Disorders, 2020
This study examined age trends in anxious and depressive symptoms, from older adolescence to old age, and explored the association between anxious and depressive symptoms with gender, ASD severity, and socio-economic factors. Two hundred and fifty-five individuals with ASD (151 males, M[subscript age] = 33.52 years, SD[subscript age] = 14.98) took…

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…

Hohn, Vanessa D.; de Veld, Danielle M. J.; Mataw, Kawita J. S.; van Someren, Eus J. W.; Begeer, Sander – Journal of Autism and Developmental Disorders, 2019
Insomnia is a common source of distress in adults with autism spectrum disorder (ASD). Two characteristics of ASD could be relevant to insomnia complaints by hampering the entrainment of a circadian sleep-wake rhythm. First, sensory hyper-reactivity could lead to bright light avoidance and thus affect photoperiodic input to the circadian system.…

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…

Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Martínez-González, A. E.; Piqueras, J. A. – Journal of Autism and Developmental Disorders, 2018
Restricted and repetitive behavior (RRB) is one of the two key diagnostic features of autism spectrum disorder (ASD). DSM-5 highlights the importance of severity-based diagnostic modifiers assigned on the basis of intensity of needed supports. Therefore, there is a need for available measures that assess the severity of RRB. The repetitive…

Heinrich, Manuel; Böhm, Julia; Sappok, Tanja – Journal of Autism and Developmental Disorders, 2018
The study assessed the diagnostic validity of the diagnostic behavioral assessment for autism spectrum disorders-revised (DiBAS-R; 19-item screening scale based on ratings by caregivers) in a clinical sample of 381 adults with ID. Analysis revealed a sensitivity of 0.82 and a specificity of 0.67 in the overall sample (70.3% agreement). Sensitivity…

Mirror neuron system (MNS) dysfunctions might underlie deficits in autism spectrum disorders (ASD). Diffusion tensor imaging based probabilistic tractography was conducted in 15 adult ASD patients and 13 matched, healthy controls. Fractional anisotropy (FA) was quantified to assess group differences in tract-related white matter microstructure of…

Nah, Yong-Hwee; Brewer, Neil; Young, Robyn L.; Flower, Rebecca – Journal of Autism and Developmental Disorders, 2018
Although depression and anxiety are the most common comorbidities in individuals with Autism Spectrum Disorder (ASD), descriptive data for their prevalence among autistic adults are limited. This study provides descriptive data for a cohort of 155 autistic adults (mean age = 27.1 years, SD = 11.9) of average IQ on the short-form version of the…

Moss, Philippa; Mandy, William; Howlin, Patricia – Journal of Autism and Developmental Disorders, 2017
The WHO Quality of Life-Brief questionnaire was used to assess quality of life (QoL) among 52 adults with autism (mean age 49 years) followed-up since childhood. Overall, assessments of QOL were more positive than measures of objective social outcome (jobs, independence, relationships etc.) but correlations between caregiver and self-reports were…
