我们研究了自闭症谱系障碍（ASD）儿童在确诊到大约6岁入学期间认知和适应行为标准分数的稳定性。2岁儿童智商提高了18分，3岁儿童提高了12分，4岁儿童提高了9分（N = 281）。不同年龄组的适应行为分数提高了4分（N = 289）。入学时，24%的儿童符合智力残疾标准（认知和适应行为分数<70）。在确诊时两项分数均≥70的儿童后来没有符合智力残疾标准的。在两个方面最初都有延迟的儿童结果更具变化性（57%的儿童两项分数仍<70）。这些研究结果与临床决策相关，包括确定自闭症谱系障碍幼儿的智力残疾情况。
We examined the stability of cognitive and adaptive behaviour standard scores in children with autism spectrum disorder (ASD) between diagnosis and school entry approximately age 6. IQ increased 18 points in 2-year-olds, 12 points in 3-year-olds, and 9 points in 4-year-olds (N = 281). Adaptive behaviour scores increased 4 points across age groups (N = 289). At school entry, 24 % of children met criteria for intellectual disability (cognitive and adaptive behaviour scores < 70). No children with both scores a parts per thousand yen70 at diagnosis later met criteria for intellectual disability. Outcomes were more variable for children with initial delays in both areas (in 57 %, both scores remained < 70). Findings are relevant to clinical decision-making, including specification of intellectual disability in young children with ASD.
