Is there a clear line between normal and abnormal mood? Studies of manifest and latent structure provide strong support for a continuum that extends from asymptomatic to subsyndromal to syndromal cases of increasing severity. Subsyndromal symptoms are impairing, predict syndrome onset and relapse, and account for more doctor's visits and suicide attempts than the full syndromes, yet they are not recognized in the current classification. For most research and some clinical activities, dimensional diagnoses are recommended, and examples are offered for how such diagnoses could be made. For clinical activities requiring decisions, a multithreshold model is proposed in which both lower (e.g., mild depression, capturing subsyndromal cases) and upper (e.g., major depression, capturing clinically significant cases) diagnostic categories are used to inform clinical care. Beyond its implications for diagnosis, the dimensionality of depression and anxiety has implications for etiology and for research aimed at understanding how emotions become disrupted in psychopathology.

正常对病理性情绪：对诊断的意义。

正常和异常情绪之间是否有清晰的界线？显性和潜伏结构的研究为从无症状到亚综合征到严重的综合症病例的连续发展提供了有力的支持。亚症候群症状正在减弱，可预测综合征的发作和复发，并且比完全症候群占更多的医生就诊次数和自杀企图，但在当前分类中并未被识别。对于大多数研究和某些临床活动，建议进行尺寸诊断，并提供有关如何进行此类诊断的示例。对于需要决策的临床活动，提出了一个多阈值模型，其中较低（例如，轻度抑郁症，捕获亚综合征病例）和较高（例如，严重抑郁症，捕获具有临床意义的病例）诊断类别可用于提供临床护理。除了对诊断的影响外，抑郁和焦虑的程度还对病因学和旨在了解情绪在心理病理学中如何被破坏的研究具有影响。
