The changes in IQ for 35 preschool retarded children evaluated and then treated in a special hospital-based program which emphasized parent participation were compared with those of 36 retarded children evaluated at the same hospital clinic, most of whom received preschool services in the community. Over an average of 16 months, the group in the hospital-based program showed a mean gain of 8.1 IQ points, and 11 children increased by 15 points or more. In contrast, the mean improvement for the community group was 0.8 IQ points, and only two children had increases of 15 points or more. With the exception of serious neglect/deprivation, there was no relationship between medical diagnosis and amount of IQ change. Children from backgrounds of poverty, with unknown and presumably non-biological etiologies, did no better than children in better social circumstances with clear organic causes. Outcome was unaffected by sex, initial IQ level, initial age or social class.
对35名在一家以医院为基础的特殊项目中接受评估并随后接受治疗的学龄前智障儿童的智商变化进行了比较，该项目强调家长参与，将其与36名在同一家医院诊所接受评估的智障儿童的智商变化进行对比，其中大多数儿童在社区接受学前服务。在平均16个月的时间里，以医院为基础的项目组智商平均提高了8.1分，11名儿童提高了15分或更多。相比之下，社区组的平均提高幅度为0.8分，只有两名儿童提高了15分或更多。除了严重忽视/剥夺的情况外，医学诊断与智商变化量之间没有关系。来自贫困背景、病因不明且可能是非生物学原因的儿童，并不比社会环境较好、有明确器质性病因的儿童表现更好。结果不受性别、初始智商水平、初始年龄或社会阶层的影响。
