Anhedonia is a common symptom of several disorders, but cost-effective treatments that focus on anhedonia specifically have been lacking. Therefore, personalized lifestyle advice has recently been investigated as a suitable means of enhancing pleasure and positive affect (PA) in young adults with anhedonia. This intervention provided individuals with a personalized lifestyle advice which was based on observed individual patterns of lifestyle behaviors and experienced pleasure in daily life. The present study extends this previous work by examining a potential mechanism of treatment success, affective reactivity.
We explored changes in affective reactivity to events in daily life from pre- to post-intervention in a subclinical sample of young adults with anhedonia (N = 69). Using the Experience Sampling Method (ESM), participants answered questions on their activities, their pleasure levels, PA and negative affect (NA) before and after the intervention.
Multilevel analysis revealed that participants did not experience an altered affective reactivity to positive events after the intervention. The affective reactivity to negative events depended on the level of improvement in mean-PA after the lifestyle advice intervention.
The present study used a subclinical sample with the majority of participants being female which limited the generalizability of the findings.
This study suggests that an altered affective reactivity to negative events is an underlying mechanism of the effectiveness of a personalized lifestyle advice.
快感缺失是几种障碍的常见症状，但缺乏针对快感缺失的具有成本效益的治疗方法。因此，最近人们研究了个性化的生活方式建议，作为提高有快感缺失的年轻成年人愉悦感和正性情绪（PA）的合适方法。这种干预为个人提供了基于观察到的个人生活方式行为模式和日常生活中的愉悦感的个性化生活方式建议。本研究通过考察治疗成功的潜在机制——情感反应，扩展了之前的工作。
我们通过经验抽样法（ESM），在有快感缺失的亚临床年轻成年人样本（N=69）中，从干预前到干预后，探索了日常生活事件的情感反应变化。参与者在干预前后回答了有关活动、愉悦水平、PA 和负性情绪（NA）的问题。
多层分析显示，参与者在干预后对积极事件的情感反应没有改变。对消极事件的情感反应取决于生活方式建议干预后平均 PA 改善的程度。
本研究使用的是亚临床样本，大多数参与者为女性，这限制了研究结果的普遍性。
本研究表明，对消极事件的情感反应改变是个性化生活方式建议有效性的潜在机制。
