Abstract：
This study examined the effects of participation in enjoyable activities and the experience of uplifting events on individuals\' momentary positive affect (PA) and tested for age differences in these effects. 176 adults (ages 25-66) completed ecological momentary assessments (EMAs) 5 times per day for 14 days. We found that individuals reported higher levels of PA at times when an uplifting event had occurred compared to times when an uplifting event had not occurred (p < 0.05), and this association was amplified among those who participated less frequently in enjoyable activities (p < 0.05). The moderating effect of participation in enjoyable activities was invariant across the sample\'s age range. The findings demonstrated that individuals who habitually participated in enjoyable activities experienced higher levels of PA in everyday life. In contrast, individuals who infrequently or never engaged in enjoyable activities depended upon recent uplifting events to experience higher levels of PA.
摘要：
这项研究检查了参与愉快活动和令人振奋的事件对个人的瞬时积极影响（PA）的影响，并测试了这些影响的年龄差异。176名成年人（25-66岁）每天完成5次生态瞬时评估（EMA），为期14天。我们发现，与未发生提升事件的时间相比，发生提升事件的时间个体报告的PA水平较高（p<0.05）。在参加较少参加愉快活动的人中，这种关联得到了放大（p<0.05）。参与愉快活动的调节作用在样本的年龄范围内是不变的。研究结果表明，习惯性地参加愉快活动的人在日常生活中经历了更高水平的PA。相比之下,不经常或从不从事令人愉快的活动的人依赖于最近的令人振奋的事件来体验更高水平的PA。
