预期快乐是指对未来事件的预期的积极影响状态，已发现它可以激发目标导向的行为。先前的研究表明，患有精神病阴性症状的患者表现出目标导向行为的减少，因为“消极信念”阻碍了预期的快乐。本研究旨在将消极信念和预期快乐与患者日常生活动机联系起来。使用经验抽样方法，我们检查了 35 名阴性症状患者和 36 名健康对照者日常生活中目标导向活动的动机过程。我们测试了患者和健康对照组之间目标导向行为的机制是否不同，以及消极信念是否通过阻碍预期快乐来干扰目标导向行为。多层次分析显示，预期愉悦介导了两组的目标意图和目标导向活动之间的关联（间接影响：24-30%）。然而，在患者组中，社会目标意图和预期快乐之间的关联较弱（b = -0.09，SE = 0.05，p
Anticipatory pleasure refers to a state of positive affect in anticipation of future events that has been found to motivate goal-directed behavior. Previous research has indicated that patients with negative symptoms of psychosis show reduced goal-directed behavior because 'demotivating beliefs' impede anticipatory pleasure. This study aims to link demotivating beliefs and anticipatory pleasure to patients' motivation in everyday life. Using the Experience Sampling Method, we examined the motivational process of goal-directed activity in the daily lives of 35 patients with negative symptoms and 36 healthy controls. We tested whether the mechanism underlying goal-directed behavior differs between patients and healthy controls and whether demotivating beliefs interfere with goal-directed behavior by impeding anticipatory pleasure. Multilevel analyses revealed that anticipatory pleasure mediated the association between goal-intentions and goal-directed activity in both groups (indirect effects: 24-30%). In the patient group, however, the association between social goal-intentions and anticipatory pleasure was weaker (b=-0.09, SE= 0.05, p
