Anhedonia has been proposed as a psychological marker for biological depression. In this study, anhedonia was measured in a cohort of chronically depressed outpatients. Levels of anhedonia were similar to those reported in acutely depressed patients. Anhedonia was significantly correlated with morbid risk of depression in first-degree family members, neuroticism, introversion, and dysfunctional attitudes, but not with depression severity or hopelessness scores. In a naturalistic follow-up study over a 1-year period, while depression severity was significantly reduced, anhedonia scores remained constant. The study provides support for the view that in chronic depression anhedonia may have trait-like properties, and that the propensity toward anhedonic responses may occur irrespective of depressive severity.
快感缺失已被提出作为生物性抑郁的一种心理标志。在本研究中，对一组慢性抑郁症门诊患者进行了快感缺失测量。其快感缺失水平与急性抑郁症患者报告的水平相似。快感缺失与一级家庭成员的抑郁发病风险、神经质、内向性及功能失调性态度显著相关，但与抑郁严重程度或绝望得分无关。在一项为期1年的自然随访研究中，虽然抑郁严重程度显著降低，但快感缺失得分保持不变。该研究支持了以下观点：在慢性抑郁症中，快感缺失可能具有特质样属性，并且无论抑郁严重程度如何，都可能出现快感缺失反应倾向。
