Popis: Pain-related anxiety can contribute to increased pain sensitivity and create a barrier to receiving routine medical care. For individuals with autism spectrum disorders (ASD), behavioral response patterns suggest increased pain sensitivity. Neuroimaging studies in ASD suggest altered evaluation or emotional processing of pain which could contribute to pain-related anxiety. However, the relationship between pain sensitivity and pain-related anxiety is not clear in ASD. We hypothesized that individuals with ASD would report higher pain intensity during supra-threshold pain stimuli and endorse more pain-related anxiety, compared to a typical comparison group. We recruited 29 adults (ASD, n=15; TD, n=14) for a series of heat pain tasks (applied to the calf), including heat pain thresholds using a method of limits approach and two supra-threshold tasks. We examined supra-threshold pain using a pain-rating curve, where 7 temperatures (40-48°C) were presented for 5s (5 trials each), and a sustained heat pain task with alternating low (42°C) and high (46°C) temperatures for 21s (6 trials each, 30s inter-trial rest). Pain-related anxiety was assessed using the Pain Anxiety Symptoms Scale-20 (PASS), Fear of Pain Questionnaire-III (FOP-III), and the Situational Pain Catastrophizing Scale (regarding the sustained pain task). While there were no group differences in pain thresholds, mean pain ratings were higher in the ASD group for all temperatures in the pain rating curve (all p
