摘要
本研究的目的是建立抑郁症快感缺乏的统计模型。研究纳入748例健康对照(女性350例，占46.79%，年龄21.27±4.72)和80例患者(女性32例，占40%，年龄38.36±16.42)。采用生理快感缺失量表(PhAS)、社会快感缺失量表(CSAS)、正、负情感量表(PANAS)和贝克抑郁量表(BDI)进行测试。采用经典测量理论(CTT)和项目反应理论(IRT)对所收集的数据进行分析。结果发现，抑郁状态一般因素与积极情绪(r = -0.37, P < 0.05)、消极情绪(r = 0.62, P < 0.05)、BDI (r = 0.48, P < 0.01)显著相关。在对照组和患者之间也观察到显著差异。抑郁症快感缺乏症的双因素模型比一维模型更符合数据。双因素模型似乎对描述抑郁症中的快感缺乏很有用。
Body and Social Anhedonia of Depression: A Bifactor Model Analysis.
The purpose of this study was to develop a statistical model of anhedonia of depression. The study included 748 healthy controls (350 women, 46.79%, age 21.27 ± 4.72) and 80 patients (32 women, 40%, age 38.36 ± 16.42). The Physical Anhedonia Scale (PhAS), the Social Anhedonia Scale (CSAS), the Positive and Negative Affect Scale (PANAS) and the Beck Depression Inventory(BDI) were administered. Classical Measurement Theory (CTT) and Item Response Theory (IRT) were applied to the collected data. We observed that the general factor of depression status was significantly related with positive emotion (r = -0.37, P < 0.05), negative emotion (r = 0.62, P < 0.05) and BDI (r = 0.48, P < 0.01). A significant difference also was observed between controls and patients. The bifactor model of anhedonia of depression provided a better fit to the data than a unidimensional model. The bifactor model appears to be useful to describe anhedonia in depression.
