“…In recent years, multiple studies on MI/DIF have been carried out with different ASD symptom measures, including the Childhood Autism Rating Scale (CARS) (Schopler et al, 1988(Schopler et al, , 2010, ADOS (Lord et al, 2000(Lord et al, , 2012, Social Responsiveness Scale, and ADI-R (Constantino, 2005;Constantino and Gruber, 2012). These studies primarily focused on the effects of race/ethnicity, sex/gender and chronological age on scores (ADOS: Harrison et al, 2017;Ronkin et al, 2021;Burrows et al, 2022;Kalb et al, 2022;CARS: Stevanovic et al, 2021;SRS and ADI-R: Frazier and Hardan, 2017), with a few studies also investigating MI across groups with or without ID (Sturm et al, 2017;Dovgan et al, 2019). While these studies provided preliminary evidence that ASD symptom measures should take the impact of cognitive abilities into account, understanding of how cognitive or language abilities influence the measurement of specific ASD symptoms is still limited.…”
