注意力缺陷/多动障碍(ADHD)是注意力和执行功能障碍的连续体，还是一个自然的类别，这一问题尚未得到广泛的研究。对437名被推荐进行神经心理评估的个体的主观报告和神经心理数据进行了潜在类别和分类分析(均值高于-低于一个切点[MAMBAC]、最大特征值[MAXEIG]和潜在模式[LMODE])。结果表明，没有明显的证据表明ADHD在多个程序和指标集上有分类表现。同样，没有证据表明ADHD亚型代表质的区别。这些发现可能表明，目前的诊断概念化不足以准确地识别和表征与注意力和执行功能障碍相关的问题。或者，无效的调查结果可能是由于指标选择不足造成的。维度模型可以更好地帮助准确识别有功能损害风险的个人。
The question of whether attention-deficit/hyperactivity disorder (ADHD) represents a continuum of attentional and executive dysfunction or a natural category has yet to be extensively investigated. Subjective report and neuropsychological data from 437 individuals referred for neuropsychological evaluation were analyzed using latent class and taxometric analyses (mean above minus below a cut [MAMBAC], maximum eigenvalue [MAXEIG], and latent mode [LMODE]). Results indicated no significant evidence for a taxonic representation of ADHD across multiple procedures and indicator sets. Similarly, there was no evidence that ADHD subtypes represent a qualitative distinction. These findings may suggest that current diagnostic conceptualizations are inadequate for accurately identifying and characterizing individuals with problems related to attention and executive dysfunction. Alternatively, the null findings may have resulted from inadequate indicator selection. A dimensional model may better facilitate accurate identification of individuals at risk for functional impairment.
