The assessment of autism in individuals with mild intellectual disabilities (MID) is complicated because of the overlap between autistic traits and intellectual limitations. Impaired social emotional reciprocity is a core diagnostic criterion for autism. However, it is unknown whether reciprocal behaviour differs between MID individuals with or without an autism spectrum disorder (ASD). This study explored differences in reciprocal behaviour of 35 children and adolescents with MID (intelligence quotient 50-85): 15 with ASD (ASD-MID) and 20 with typical development (TD-MID) using the Interactive Drawing Test (IDT). ASD-MID participants showed a lower quality of reciprocal behaviour compared with TD-MID participants. The difference in quality of reciprocal behaviour between ASD-MID and TD-MID participants was not significantly related with Peabody Picture Vocabulary Test scores and thus not attributable to verbal capacity. The IDT is likely to reflect the child's inclination to display reciprocal behaviour in everyday situations, as its scale scores were meaningfully associated with the level of social cognition assessed with the Social Responsiveness Scale. Thus, the IDT seems well suited for measuring impairments in reciprocal behaviour in children and adolescents with MID.
由于自闭症特征与智力缺陷之间存在重叠，对轻度智力障碍（MID）个体的自闭症评估变得复杂。社交情感互惠受损是自闭症的核心诊断标准。然而，患有或未患有自闭症谱系障碍（ASD）的MID个体之间的互惠行为是否存在差异尚不清楚。本研究使用互动绘画测试（IDT），探索了35名患有MID（智商50 - 85）的儿童和青少年的互惠行为差异：15名患有ASD（ASD - MID），20名发育正常（TD - MID）。与TD - MID参与者相比，ASD - MID参与者表现出较低质量的互惠行为。ASD - MID和TD - MID参与者之间互惠行为质量的差异与皮博迪图片词汇测试分数没有显著相关性，因此不能归因于语言能力。IDT的量表分数与用社会反应量表评估的社会认知水平有显著关联，因此IDT可能反映了儿童在日常情境中表现出互惠行为的倾向。因此，IDT似乎非常适合测量患有MID的儿童和青少年在互惠行为方面的损伤。
