To study whether prevalence rates of Attention-Deficit/Hyperactivity Disorder (ADHD) are related to size of school district, diagnostic method, and referral process, the ADHD Survey was mailed to all 311 superintendents of school districts in a midsouthern state; 128 (41.1%) were returned. Analysis showed no significant relationships; however, the low return rate suggests replication in other regions is necessary.
为研究注意力缺陷多动障碍（ADHD）的患病率是否与学区规模、诊断方法及转诊流程有关，我们将ADHD调查问卷邮寄给了美国中南部一个州的所有311位学区负责人；共收回128份（41.1%）。分析表明不存在显著关联；然而，低回收率表明有必要在其他地区重复此项研究。
