Intelligence (IQ) scores are used in educational and vocational planning for individuals with autism spectrum disorder (ASD) yet little is known about the stability of IQ throughout development. We examined longitudinal age-related IQ stability in 119 individuals with ASD (3-36 years of age at first visit) and 128 typically developing controls. Intelligence measures were collected over a 20-year period. In ASD, Full Scale (FSIQ) and Verbal (VIQ) Intelligence started lower in childhood and increased at a greater rate with age relative to the control group. By early adulthood, VIQ and working memory stabilized, whereas nonverbal and perceptual scores continued to change. Our results suggest that in individuals with ASD, IQ estimates may be dynamic in childhood and young adulthood.
智力（IQ）分数在自闭症谱系障碍（ASD）个体的教育和职业规划中被使用，但对于整个发展过程中 IQ 的稳定性知之甚少。我们研究了 119 名 ASD 个体（首次就诊时年龄为 3-36 岁）和 128 名正常发育对照者的纵向年龄相关 IQ 稳定性。在 20 年的时间里收集了智力测量结果。在 ASD 中，全量表智商（FSIQ）和言语智商（VIQ）在儿童时期较低，相对于对照组，随着年龄的增长，增加速度更快。在成年早期，VIQ 和工作记忆稳定下来，而非言语和知觉分数继续变化。我们的研究结果表明，在 ASD 个体中，IQ 估计在儿童和青少年时期可能是动态的。
