Möller et al. (1989) investigated the effects of sleep deprivation on depressive patients using a single-case analysis based on Kleiter's 1986 approach. Here it is discussed why it is so difficult to perform single-case analyses and why Kleiter's approach in particular may lead to wrong interpretations of the data. It is indicated that any kind of single-case analysis is based on assumptions which possibly do not hold and that it is therefore always precarious to base substantial conclusions on this type of analysis.
默勒等人（1989年）基于克莱特1986年的方法，采用单病例分析研究了睡眠剥夺对抑郁症患者的影响。本文将讨论为何进行单病例分析如此困难，以及为何克莱特的方法尤其可能导致对数据的错误解读。研究表明，任何形式的单病例分析都基于可能不成立的假设，因此基于此类分析得出实质性结论总是存在风险的。
