The aim of the study was to explore the relationships between recent changes of anhedonia or particular symptoms of recent changes of anhedonia and suicidal ideation taking into account the severity of suicidal ideations. In a group of 173 medical students, scores of the anhedonia subscale (ANH-BDI) of the BDI-II (i.e. 4 anhedonia items: loss of pleasure, loss of interest, loss of energy and loss of interest in sex) were compared between 95 subjects without suicidality, 24 subjects with life-time suicidal ideation, 28 subjects with recent suicidal ideation and 26 planners. Analyses of covariance (ANCOVA) were performed referring to groups as independent variables, the cognitive-affective subscale (CA-BDI) of the BDI-II as a covariate, the ANH-BDI and each of the four anhedonia items as dependent variables. High levels of loss of interest characterized planners when compared to the other three groups. Loss of interest could be associated with recent and severe suicidal ideation.

该研究的目的是探讨近期快感缺失的变化或近期快感缺乏变化的特定症状与自杀意念之间的关系，同时考虑到自杀意念的严重程度。在一组由 173 名医学生组成的小组中，比较了 BDI-II 的快感缺失子量表 (ANH-BDI) 的分数（即 4 个快感缺乏项目：快乐丧失、兴趣丧失、精力丧失和性兴趣丧失） 95 名没有自杀倾向的受试者，24 名有终生自杀意念的受试者，28 名近期有自杀意念的受试者和 26 名有自杀意念的受试者。进行协方差分析 (ANCOVA)，将各组作为自变量，将 BDI-II 的认知情感子量表 (CA-BDI) 作为协变量，将 ANH-BDI 和四个快感缺失项目中的每一个作为因变量。与其他三组相比，规划者的兴趣丧失程度较高。兴趣的丧失可能与最近严重的自杀意念有关。
