Discriminant function analysis was employed to study the ability of the Geriatric Mental Status interview to distinguish between patients diagnosed by the project as having an organic brain syndrome or a functional psychiatric disorder. In both New York and London, patients with organic brain syndrome scored significantly higher (p less than 0.05) than those with functional disorders on the factors of impaired memory, disorientation and incomprehensibility and significantly lower on the factors of depression and somatic concerns. Discriminant functions calculated from data on the New York and London patients separately significantly distinguished not only the patients on whom the functions were based but the patients in the other sample as well.
采用判别函数分析来研究老年精神状态访谈区分该项目诊断为患有器质性脑综合征或功能性精神障碍患者的能力。在纽约和伦敦，患有器质性脑综合征的患者在记忆受损、定向障碍和理解障碍因素上的得分显著高于（p小于0.05）患有功能性障碍的患者，而在抑郁和躯体关注因素上的得分则显著低于后者。分别根据纽约和伦敦患者的数据计算出的判别函数不仅能显著区分构建这些函数所依据的患者，还能区分另一样本中的患者。
