Journal ArticleDOI

A review of decreased sound tolerance in autism: Definitions, phenomenology, and potential mechanisms.

TL;DR: This article argues against conceptualizing DST as a unified construct, suggesting that it be separated into three phenomenologically distinct conditions: hyperacusis, misophonia, and phonophobia, each responsible for a portion of observed DST behaviors.
Journal ArticleDOI

Psychometric Evaluation of the Short Sensory Profile in Youth with Autism Spectrum Disorder.

TL;DR: Overall, the findings discourage the use of the SSP total score and most subscale scores in children with ASD and suggest that while reliable, the S SP total score is substantially biased by individual differences on dimensions other than the general factor.
Journal ArticleDOI

Measuring Depression in Autistic Adults: Psychometric Validation of the Beck Depression Inventory-II.

TL;DR: The results collectively indicate that the BDI-II is a valid measure of depressive symptoms in autistic adults, appropriate for quantifying depression severity in research studies or screening for depressive disorders in clinical settings.
Journal ArticleDOI

Cortical Auditory Processing of Simple Stimuli Is Altered in Autism: A Meta-analysis of Auditory Evoked Responses.

TL;DR: For instance, the authors found that autistic individuals exhibited prolonged P1/M50 latencies (g ǫ 0.341 [95% credible interval of 0.093, 0.619, −0.812, −1.278, −−0.187), and reduced N2 amplitudes (gǫ −0.374 [−0.633, − − 0.166,, 0.534], although this effect was primarily driven by smaller responses to the first click stimulus.
Journal ArticleDOI

Prevalence of Decreased Sound Tolerance (Hyperacusis) in Individuals With Autism Spectrum Disorder: A Meta-Analysis.

TL;DR: In this paper, the authors conducted a systematic review and meta-analysis estimating the current and lifetime prevalence of hyperacusis in children, adolescents, and adults with autism spectrum disorder (ASD).
