The authors administered semi-structured interviews to 187 psychiatric inpatients to determine the role of anhedonia in schizophrenia. The interviews were taperecorded and then given blind ratings for anhedonia on a 7-point scale. Schizophrenic patients had significantly more anhedonia than nonschizophrenics, although many of the latter group had anhedonic tendencies. Most of the difference between the groups resulted from high anhedonia scores for chronic schizophrenics; less anhedonia was found in the acute schizophrenic patients. The data indicate that anhedonia is not necessary or unique to schizophrenia but is a prominent factor in chronic schizophrenia.
作者对187名精神科住院患者进行了半结构化访谈，以确定快感缺失在精神分裂症中的作用。访谈进行了录音，然后对快感缺失进行7分制的盲评。精神分裂症患者的快感缺失明显多于非精神分裂症患者，尽管后者中的许多人也有快感缺失倾向。两组之间的差异主要源于慢性精神分裂症患者的高快感缺失得分；急性精神分裂症患者的快感缺失较少。数据表明，快感缺失并非精神分裂症所必需或独有的，但却是慢性精神分裂症的一个突出因素。
