Many psychiatric patients seem to suffer from a multitude of psychiatric disorders. The term 'comorbidity' was introduced to characterise that situation. This term, however, is multi-interpretable and thus conceals more than it clarifies. Five interpretations of the concept of comorbidity are discussed, in conjunction with the consequences their validity would have for psychiatric research, in particular for the biological branch. If the term comorbidity continues to be used without further qualification, it will slow down the process of conceptualization of novel research strategies in experimental psychiatry, which is so urgently needed.
许多精神科患者似乎患有多种精神障碍。“共病”这一术语就是用来描述这种情况的。然而，这个术语有多种解释，因此它所掩盖的比所阐明的更多。本文讨论了共病概念的五种解释，以及它们的有效性对精神科研究，特别是对生物分支研究的影响。如果继续不加进一步限定地使用共病这一术语，将会减缓实验精神病学中急需的新研究策略的概念化进程。
