Identifying causes of healthy behaviors is important for harnessing health benefits. A growing body of experience sampling research suggests that positive emotion may drive these behaviors. However, it is not known how long elevations in positive emotion facilitate these behaviors in daily life. The present study tested how time between signals moderates the association between within-person positive affect and healthy behaviors. A sample of 197 college students completed a 10-day experience sampling diary, with 5 signals a day, measuring affect and healthy behaviors. We replicated results from Nylocks and colleagues (2018) finding that within-person positive affect predicted engagement in healthy behaviors; however, this association was only significant within the same day, and not across days (i.e. overnight). Taken together, these findings highlight the importance of considering positive affect, rather than negative affect in patients with psychopathology, to improve behavioral interventions targeted to increase engagement in healthy behaviors.

确定健康行为的原因对于利用健康益处很重要。越来越多的经验抽样研究表明，积极情绪可能会推动这些行为。然而，目前尚不清楚积极情绪的升高多久会促进日常生活中的这些行为。本研究测试了信号之间的时间如何调节人内积极情绪与健康行为之间的关联。一个由 197 名大学生组成的样本完成了为期 10 天的体验抽样日记，每天有 5 个信号，测量情感和健康行为。我们复制了 Nylocks 及其同事（2018 年）的结果，发现人内的积极影响预测了健康行为的参与度；然而，这种关联仅在同一天内显着，而不是跨天（即隔夜）。综合起来，
