以前的研究将抑郁症分为三种主要症状（抑郁情绪，躯体抱怨和快感缺乏）;因此，有必要单独检查每种症状，而不是将抑郁症作为一种综合征。抑郁症的行为理论表明，由于回避而导致的环境奖励减少会加剧抑郁症。然而，这三个症状和回避之间的关系，作为中介的环境奖励还没有得到充分的研究。本研究的目的是使用抑郁症的三症状分类，并澄清如何避免和减少环境奖励恶化这些症状使用中介分析。参与者是101名诊断为重度抑郁症的日本成年人，他们完成了一份问卷，以测量他们的抑郁症状，回避和环境奖励。中介分析表明，躯体抱怨与回避的直接效应和环境奖励的间接效应显著相关，快感缺乏与环境奖励的间接效应显著相关，而抑郁情绪与回避和环境奖励均不相关。因此，本研究揭示了回避，环境奖励和抑郁症症状之间的关系取决于个人的症状类型。
Previous studies have categorized depression into three major symptoms (depressed mood, somatic complaints, and anhedonia); thus, it becomes necessary to examine each symptom separately rather than depression as a syndrome. The behavioral theory of depression suggests that it is exacerbated by reduced environmental rewards caused due to avoidance. However, the relationship between the three symptoms and avoidance, as mediated by environmental rewards has not been sufficiently examined. The purpose of this study was to use the three-symptom classification of depression and clarify how avoidance and reduced environmental rewards worsen these symptoms using a mediation analysis. The participants were 101 clinical patients diagnosed with major depressive disorder in Japanese adults, who completed a questionnaire to measure their depressive symptoms, avoidance, and environmental rewards. The mediation analysis showed that somatic complaints were significantly associated with the direct effect of avoidance and the indirect effect of environmental rewards, and anhedonia was significantly associated with the indirect effect of environmental rewards, whereas depressed mood was not associated with avoidance and environmental rewards. Therefore, the present study revealed that the relationship between avoidance, environmental rewards, and symptoms of depression differed depending on the individual symptom type.
