虽然分类诊断是由临床医生和那些希望收集同质群体的患者进行研究项目的价值，在非精神病性精神障碍领域，他们对应的实际临床综合征差。事实上，患者经常同时满足几套分类标准。一个更简约的代表性的心理学可以通过使用一个维度模型的症状-与两个相关的轴对应的焦虑和抑郁的评级来自目前的状态检查。综合国际诊断访谈可能会产生第三个维度-躯体症状-因为症状内容完全不同。初步资料分析显示，躯体症状维度与焦虑、抑郁均相关。在维度空间的特定区域中的症状个体将满足分类诊断的几个标准，从而显示共病。然而，这些疾病是不同的证据是远远没有说服力的，因为他们似乎有几个共同的原因。
Although categorical diagnoses are valued by clinicians and those wishing to collect homogeneous groups of patients for research projects, in the field of non-psychotic mental disorders they correspond poorly to actual clinical syndromes. Indeed, patients often satisfy several sets of categorical criteria simultaneously. A more parsimonious representation of-symptomatology can be obtained by using a dimensional model for symptoms - with two correlated axes corresponding to anxiety and depression for ratings derived from the Present State Examination. The Composite International Diagnostic Interview is likely to produce a third dimension - somatic symptoms - because of a radically different symptom content. Preliminary data analysis indicates that the somatic symptoms dimension correlates with both anxiety and depression. Symptomatic individuals in particular areas of dimensional space will satisfy several criteria for categorical diagnoses, and thus display comorbidity. However, evidence that these disorders are distinct is far from persuasive, as they appear to share several common causes.
