Scales for the measurement of social and physical anhedonia, the lowered ability to experience pleasure, were investigated. Both scales were devised by Chapman et al. German versions of these two patient populations and two groups of normal subjects. The reliability and scale intercorrelation coefficients were acceptable for the scales overall, but not for the separate subscales. Patients scored higher on both scales than normal subjects, and patients with neurotic depression had higher scores than those with a diagnosis of schizophrenia. A significant correlation with a chronic course was identified in the schizophrenic patients. Item analysis and factor analysis did not reveal any significant common dimensions in the 87 items in the original scales. Only 17 items in the physical anhedonia scale and 26 items in the social anhedonia scale met test-theoretical criteria of acceptability for inclusion in a German version of these scales. Discrepancies and congruencies between American and German studies were discussed, as were further criteria that might make it possible to improve research instruments of this kind.
对用于测量社交性快感缺失和躯体性快感缺失（即体验愉悦能力降低）的量表进行了研究。这两个量表均由查普曼等人设计。研究了这两个量表在两组患者群体和两组正常受试者中的德文版本。量表整体的信度和量表相互关联系数是可以接受的，但各单独子量表的情况并非如此。患者在两个量表上的得分均高于正常受试者，且神经症性抑郁症患者的得分高于精神分裂症诊断患者。在精神分裂症患者中发现与慢性病程存在显著相关性。项目分析和因子分析未在原始量表的87个项目中揭示任何显著的共同维度。躯体性快感缺失量表中只有17个项目以及社交性快感缺失量表中只有26个项目符合纳入这些量表德文版本的测试理论可接受标准。讨论了美国和德国研究之间的差异与一致性，以及可能有助于改进此类研究工具的进一步标准。
