AIM Reward sensitivity affects individuals' motivation to engage in goal-directed behavior. Other concepts, critical for reward appraisal, that potentially influence activity participation encompass delay discounting and anhedonia. The aim of this study was to test the hypothesis that anhedonia and delay discounting influence the relationship between reward sensitivity and activity engagement. METHODS In total, 37 inpatient patients with an alcohol use disorder (AUD) and 37 matched healthy controls completed the behavioral activation system scale (BAS scale), the Pleasant Activities List (PAL), the Snaith-Hamilton Pleasure Scale (SHAPS) and the Delay Discounting Task (DDT). RESULTS Patients differed from controls on SHAPS, DDT-k, PAL substance-related activities (SRA), but not BAS and PAL non-substance-related activities (non-SRA). Correlational analyses revealed a strong correlation between BAS and PAL non-SRA in both patients (r = 0.53) and controls (r = 0.47), but also with PAL-SRA in patients (r = 0.40), although not controls (r = 0.09). BAS was negatively correlated with SHAPS in both groups and with DDT in controls. SHAPS was negatively linked to PAL non-SRA in both groups. The BAS-PAL non-SRA relationship was influenced by discount rates in controls. CONCLUSION A strong link exists between reward sensitivity and engagement in non-SRA in both groups. Delay discounting affects the reward sensitivity and non-SRA association in healthy controls, while anhedonia did not impact the association between reward sensitivity and engagement in (non-)SRA in both conditions.

奖励敏感性和活动参与之间的关联：延迟贴现和快感缺乏症的影响。

AIM奖励敏感性会影响个人进行目标导向行为的动机。对于奖励评估至关重要的其他可能影响活动参与的概念包括延迟贴现和快感缺失。这项研究的目的是检验以下假设：快感不足和延迟贴现会影响奖励敏感性和活动参与之间的关系。方法总共有37名住院患者患有酒精使用障碍（AUD）和37名匹配的健康对照者完成了行为激活系统量表（BAS量表），愉悦活动量表（PAL），Snaith-Hamilton愉悦量表（SHAPS）和延迟折扣任务（DDT）。结果患者与SHAPS，DDT-k，PAL物质相关活动（SRA）的对照有所不同，但BAS和PAL非物质相关活动（non-SRA）则无差异。相关性分析显示，BAS和PAL非SRA在患者（r = 0.53）和对照组（r = 0.47）之间均具有很强的相关性，但在患者（r = 0.40）中也与PAL-SRA之间（尽管对照组（r = 0.09）无关） ）。两组中BAS与SHAPS呈负相关，与对照组中DDT呈负相关。两组的SHAPS与PAL非SRA均呈负相关。BAS-PAL非SRA关系受到控件中折现率的影响。结论两组的奖励敏感性和参与非SRA之间存在紧密联系。延迟贴现会影响健康对照者的奖励敏感性和非SRA关联，而在两种情况下，狂躁症都不会影响奖励敏感性与（非）SRA参与的关联。53）和对照组（r = 0.47），但也有PAL-SRA的患者（r = 0.40），但非对照组（r = 0.09）。两组中BAS与SHAPS呈负相关，与对照组中DDT呈负相关。两组的SHAPS与PAL非SRA均呈负相关。BAS-PAL非SRA关系受到控件中折现率的影响。结论两组的奖励敏感性和参与非SRA之间存在紧密联系。延迟贴现会影响健康对照者的奖励敏感性和非SRA关联，而在两种情况下，狂躁症都不会影响奖励敏感性与（非）SRA参与的关联。53）和对照组（r = 0.47），但也有PAL-SRA患者（r = 0.40），尽管没有对照组（r = 0.09）。两组中BAS与SHAPS呈负相关，与对照组中DDT呈负相关。两组的SHAPS与PAL非SRA均呈负相关。BAS-PAL非SRA关系受到控件中折现率的影响。结论两组的奖励敏感性和参与非SRA之间存在紧密联系。延迟贴现会影响健康对照者的奖励敏感性和非SRA关联，而在两种情况下，狂躁症都不会影响奖励敏感性与（非）SRA参与的关联。两组的SHAPS与PAL非SRA均呈负相关。BAS-PAL非SRA关系受到控件中折现率的影响。结论两组的奖励敏感性和参与非SRA之间存在紧密联系。延迟贴现会影响健康对照者的奖励敏感性和非SRA关联，而在两种情况下，狂躁症都不会影响奖励敏感性与（非）SRA参与的关联。两组的SHAPS与PAL非SRA均呈负相关。BAS-PAL非SRA关系受到控件中折现率的影响。结论两组的奖励敏感性和参与非SRA之间存在紧密联系。延迟贴现会影响健康对照者的奖励敏感性和非SRA关联，而在两种情况下，狂躁症都不会影响奖励敏感性与（非）SRA参与的关联。
