In this study of 101 patients who met DSM-III criteria for major depression, those with extreme anhedonia (N = 23) were younger, more depressed, and less neurotic than the patients with a normal-range capacity for pleasurable experiences (N = 78). The anhedonic depressed patients recovered more rapidly; at discharge they consequently had levels of symptom severity equal to those of the hedonic patients, yet they remained significantly more anhedonic. The anhedonic patients exhibited loss of pleasure in appetite, sex, social contacts, and work, which suggests a global dulling of the capacity for pleasure.
在这项针对101名符合《精神疾病诊断与统计手册》第三版（DSM-III）重度抑郁症标准的患者的研究中，与愉悦体验能力处于正常范围的患者（N = 78）相比，有极度快感缺失的患者（N = 23）更年轻、抑郁程度更高且神经质程度更低。快感缺失的抑郁症患者康复得更快；出院时，他们的症状严重程度与有快感的患者相当，但他们的快感缺失程度仍显著更高。快感缺失的患者在食欲、性、社交和工作方面都表现出愉悦感缺失，这表明愉悦能力整体减退。
