这项研究考察了自闭症谱系障碍高风险 (HR) 与低风险 (LR) 婴儿的手势和言语的纵向生长情况。在 8 至 14 个月以及 18 和 24 个月期间，每月对 14 名诊断为 ASD 的 HR 婴儿 (HR-ASD)、27 名患有语言迟缓的 HR 婴儿 (HR-LD)、51 名未诊断为 HR 的婴儿 (HR-ND) 和 28 名 LR 婴儿的护理人员进行麦克阿瑟-贝茨交际发展调查问卷。 LR 和 HR-ND 婴儿之间几乎没有差异，但 HR-LD 和 HR-ASD 组在初始技能水平和生长模式方面存在差异。虽然 HR-LD 婴儿的生长速度与 LR 和 HR-ND 婴儿相当，但 HR-ASD 组的生长减弱，其轨迹逐渐偏离所有其他组。
This study examined longitudinal growth in gestures and words in infants at heightened (HR) versus low risk (LR) for ASD. The MacArthur-Bates Communicative Development Inventory was administered monthly from 8 to 14 months and at 18 and 24 months to caregivers of 14 HR infants diagnosed with ASD (HR-ASD), 27 HR infants with language delay (HR-LD), 51 HR infants with no diagnosis (HR-ND), and 28 LR infants. Few differences were obtained between LR and HR-ND infants, but HR-LD and HR-ASD groups differed in initial skill levels and growth patterns. While HR-LD infants grew at rates comparable to LR and HR-ND infants, growth was attenuated in the HR-ASD group, with trajectories progressively diverging from all other groups.
