对注意力缺陷多动障碍(ADHD)的潜在结构的理解对于开发这种疾病的因果模型至关重要。虽然一些研究人员认为ADHD是维度的,其他人则认为它是分类的,但直接研究ADHD的潜在结构的研究相对较少。作者使用NICHD早期儿童保育和青少年发展研究的数据进行了一系列分类分析(ns在667-1078之间)。结果显示,在各种不同的分析和指标集,注意力不集中,多动/冲动和ADHD的维度潜在结构。此外,与相关功能的相关性分析表明,维度模型表现出更强的有效性系数与这些标准的措施比二分模型。这些发现与最近关于ADHD遗传基础的研究以及当代ADHD模型相一致。
An understanding of the latent structure of attention-deficit/hyperactivity disorder (ADHD) is essential for developing causal models of this disorder. Although some researchers have presumed that ADHD is dimensional and others have assumed that it is taxonic, there has been relatively little research directly examining the latent structure of ADHD. The authors conducted a set of taxometric analyses using data from the NICHD Study of Early Child Care and Youth Development (ns between 667–1078). The results revealed a dimensional latent structure across a variety of different analyses and sets of indicators, for inattention, hyperactivity/impulsivity, and ADHD. Furthermore, analyses of correlations with associated features indicated that dimensional models demonstrated stronger validity coefficients with these criterion measures than dichotomous models. These findings jibe with recent research on the genetic basis of ADHD and with contemporary models of ADHD.
