An analysis aiming to functionally subgroup seriously conduct disordered adolescents identified grade of onset of persistent classroom misconduct as the single most useful and discriminating variable for this purpose. Students whose misconduct began in the early elementary school were characterized by a prominent degree of developmental-educational limitations, whereas those with a later onset were--like the control group--remarkably free of early risk factors.
一项旨在对患有严重品行障碍的青少年进行功能亚组分析的研究发现，持续性课堂不当行为的起始年级是实现这一目的最有用且最具区分性的单一变量。不当行为始于小学低年级的学生具有显著程度的发展教育局限，而那些起始较晚的学生——与对照组一样——基本没有早期风险因素。
