We observed infant siblings of children with autism later diagnosed with ASD (ASD siblings; n = 17), infant siblings of children with autism with and without other delays (Other Delays and No Delays siblings; n = 12 and n = 19, respectively) and typically developing controls (TD controls; n = 19) during a free-play task at 18 months of age. Functional, symbolic, and repeated play actions were coded. ASD siblings showed fewer functional and more non-functional repeated play behaviors than TD controls. Other Delays and No Delays siblings showed more non-functional repeated play than TD controls. Group differences disappeared with the inclusion of verbal mental age. Play as an early indicator of autism and its relationship to the broader autism phenotype is discussed.
我们在18个月大的自由玩耍任务中观察了后来被诊断为自闭症谱系障碍（ASD）的自闭症儿童的婴儿兄弟姐妹（ASD兄弟姐妹；n = 17）、有和没有其他发育迟缓的自闭症儿童的婴儿兄弟姐妹（分别为其他发育迟缓兄弟姐妹和无发育迟缓兄弟姐妹；n = 12和n = 19）以及发育正常的对照组（TD对照组；n = 19）。对功能性、象征性和重复性玩耍行为进行了编码。与TD对照组相比，ASD兄弟姐妹表现出更少的功能性重复玩耍行为和更多的非功能性重复玩耍行为。其他发育迟缓兄弟姐妹和无发育迟缓兄弟姐妹表现出比TD对照组更多的非功能性重复玩耍行为。纳入语言心理年龄后，组间差异消失。讨论了玩耍作为自闭症的早期指标及其与更广泛自闭症表型的关系。
