目的神经发育障碍的患病率估计是通过单一评分者的问卷调查来计算的，这引入了固有的评分者偏差。本研究旨在评估四种神经发育障碍的患病率和共病率。方法对3852名6 ~ 9岁儿童进行社区抽样调查。家长和老师使用问卷式量表评估儿童的临床状况。这些具有截断值的量表用于估计注意缺陷多动障碍、自闭症谱系障碍、特定学习障碍（或发展性阅读障碍）和发展性协调障碍的患病率和共病率。结果各评分者的患病率分别得到确认。一些估计值高于之前在其他国家进行的研究。我们还发现家长和老师的评分存在很大的差异。此外，两个评分者之间的一致程度取决于儿童临床状况的严重程度。结论这些估计是基于两种不同的评分者对儿童进行评估的首次发现。患病率和合并症的估计为儿科神经病学的研究人员和临床医生提供了信息。两种不同评分者之间的分歧引发了对先前对神经发育障碍的估计的质疑。
Aim Prevalence estimates of neurodevelopmental disorders have been calculated by questionnaire surveys scored by a single rater, which introduces inherent rater biases. The present study aimed to estimate the prevalence and comorbidity rates of four neurodevelopmental disorders based on both parent and teacher rating scales. Methods We performed a community sample survey recruiting 3852 children aged 6 to 9 years. Parents and teachers evaluated clinical conditions in children using questionnaire-style scales. These scales with cut-off values were used to estimate the prevalence and comorbidity rates of attention deficit hyperactive disorder, autism spectrum disorder, specific learning disorder (or developmental dyslexia), and developmental coordination disorder. Results The prevalence estimates were separately confirmed according to the raters. Some estimates were higher than those in previous studies conducted in other countries. We also found a large disagreement between the parent and teacher rating scores. Moreover, the degree of agreement between two raters varied depending on the severity of the child's clinical condition. Conclusion These estimates are the first findings based on evaluating children by two different raters. The prevalence and comorbidity estimates are informative for researchers and clinicians of pediatric neurology. The disagreements between two different raters raise questions about previous estimates of neurodevelopmental disorders.
