A deficit in the ability to experience pleasure (anhedonia) is one of the core symptoms of depression. However, therapy to date has predominantly focused on understanding elevations in negative emotion experience in depression and relatively neglected ways to reconnect individuals to positive experience. This article reviews current insights into blunted positivity in depression, evaluating evidence that depression leads to disturbances in anticipation (positive emotion experience when approaching a goal or a rewarding stimulus) and consummation (positive emotion experience when attaining a goal or rewarding stimulus), as well as impaired positive emotion recognition. The case is made that existing treatments are only partially effective and that therapy outcomes are likely to be improved by focusing on augmenting positivity, capitalizing on emerging insights from positive affective neuroscience. Existing and emerging therapeutic techniques that may aid the promotion of positivity are critiqued, and some suggestions for future research and clinical practice are outlined.
快感缺失(快感缺乏)是抑郁症的核心症状之一。然而,迄今为止的治疗方法主要侧重于理解抑郁症中负面情绪体验的升高,而相对忽视了使个体重新与积极体验联系起来的方法。本文综述了目前对抑郁症中积极情绪迟钝的认识,评估了抑郁症导致预期(接近目标或奖励刺激时的积极情绪体验)和完成(达到目标或奖励刺激时的积极情绪体验)紊乱以及积极情绪识别受损的证据。有人认为,现有的治疗方法只是部分有效,通过关注增强积极性,利用积极情感神经科学的新见解,治疗效果可能会得到改善。本文对现有的和新兴的治疗技术进行了批判,并为未来的研究和临床实践提出了一些建议。
