Abstract

Background

Evidence suggests that recent changes in anhedonia may be more predictive of suicidal ideation than either state or trait anhedonia alone. However, the individual role that anhedonia symptoms play in suicidality is not yet well established.

Methods

This study investigated whether state, trait, and recent changes in anhedonia predicted recent suicidal ideation, using cross-sectional data from two independent samples, one non-clinical (n = 2,138) and one clinical (n = 859), using binary logistic regression analyses.

Results

In Study 1, loss of interest in people and loss of pleasure were associated with recent suicidal ideation independent of other depression symptoms, state and trait anhedonia. In Study 2, loss of interest in people, loss of interest in sex, and work inhibition were associated with recent suicidal ideation. In both studies, recent changes in anhedonia was uniquely associated with recent suicidal ideation.

Conclusions

These results indicate that recent changes in anhedonia and particularly the social aspect of the Loss of Interest in People item could be a significant risk factor in suicidal ideation.

兴趣丧失和快感丧失在近期自杀意念中的具体作用

摘要

背景

有证据表明，最近的快感缺失变化可能比单独的状态或特征快感缺失更能预测自杀意念。然而，快感缺乏症状在自杀中所起的个人作用尚未得到很好的确定。

方法

本研究使用来自两个独立样本（一个非临床（ n  = 2,138）和一个临床（n = 859））的横断面数据 ，使用二元逻辑回归，调查了快感缺乏的状态、特征和最近的变化是否预测了最近的自杀意念分析。

结果

在研究 1 中，对人的兴趣丧失和快感丧失与最近的自杀意念有关，而与其他抑郁症状、状态和特征缺乏快感无关。在研究 2 中，对人失去兴趣、对性失去兴趣和工作抑制与最近的自杀意念有关。在这两项研究中，最近快感缺失的变化与最近的自杀意念有着独特的联系。

结论

这些结果表明，最近快感缺失的变化，特别是对人失去兴趣项目的社会方面可能是自杀意念的重要风险因素。
