In the course of a prospective longitudinal study, we examined age of onset of behavior problems in a group of boys and girls identified with attention deficit disorder (ADD) at age 11. Onset occurred during the preschool years, by the first year of schooling, or by the end of the second year of school. Onset was strongly related to informant source at age 11, pattern of comorbidity of disorder at age 11, and developmental language, perceptual motor, and IQ measures. Onset by the first year of schooling was particularly related to poor reading skills. By age 15, nearly three-quarters of those with onset of problems before age 6 had one or more DSM-III disorders.
在一项前瞻性纵向研究过程中，我们调查了一组11岁时被诊断为注意力缺陷障碍（ADD）的男孩和女孩出现行为问题的起始年龄。问题起始于学前阶段、入学第一年或二年级末。起始年龄与11岁时的信息提供者来源、11岁时的共病模式以及发育语言、感知运动和智商测量指标密切相关。入学第一年出现问题尤其与阅读能力差有关。到15岁时，6岁前出现问题的儿童中近四分之三患有一种或多种《精神疾病诊断与统计手册》第三版（DSM-III）中的疾病。
