The predictability, consistency in group means, and intra-individual stability of developmental quotients and performance IQs were assessed from preschool to school age for 71 autistic children and 71 non-autistic communication-handicapped children, matched on chronological age, sex and initial performance IQ/DQ. DQs/performance IQs at age 4 yrs were found to be highly correlated with performance IQ at age 10 yrs for both groups. Absolute difference scores and group means were also equivalent for both samples, with no difference in patterns of change or the relationship between performance IQ and language status, as measured on the PPVT. Differences between diagnostic groups occurred only for scores on the Vineland Social Maturity Scale and the relationship between these scores and IQ.
对71名自闭症儿童和71名非自闭症沟通障碍儿童从学龄前到学龄期的发育商数和操作智商的可预测性、组内均值的一致性以及个体内稳定性进行了评估，这些儿童在实际年龄、性别和初始操作智商/发育商数方面相匹配。结果发现，两组儿童4岁时的发育商数/操作智商与10岁时的操作智商高度相关。两个样本的绝对差异分数和组内均值也相当，在变化模式或操作智商与语言状况之间的关系方面没有差异（以皮博迪图片词汇测验衡量）。诊断组之间的差异仅出现在文兰社会成熟量表的分数以及这些分数与智商之间的关系上。
