Usually the severeness of cyclothymical depression is assessed by self-or arbiter's evaluation scales. These assessments are influenced by - mainly verbal - disturbing variables that hitherto may hardly be controlled. Measurements of performance provide less falsified results. However, they are influenced by the premorbid level of general intelligence and by the age of the patient. These disturbing variables, however, can be controlled rather well. Empirical investigations show that the assessment of the severeness of cyclothymical depression measured by performance tests of evaluation scales leads to different results. Nevertheless, both types of tests are valid for measuring depressions. Therefore, both are to be taken into account for assessment of severeness.
通常，环形心境障碍性抑郁的严重程度是通过自我或他人评估量表来评定的。这些评估受到——主要是言语方面的——干扰变量的影响，而这些变量迄今为止几乎无法得到控制。行为表现测量能提供较少失真的结果。然而，它们会受到病前总体智力水平和患者年龄的影响。不过，这些干扰变量是可以得到较好控制的。实证研究表明，通过评估量表的行为测试来测量环形心境障碍性抑郁的严重程度会得出不同的结果。尽管如此，这两种测试类型在测量抑郁症方面都是有效的。因此，在评估严重程度时，两者都应予以考虑。
