Although value-based actions are often associated with improved mental health outcomes, few studies have explored this relationship on a daily level. The aim of this diary study was to explore how value-based actions change over time and assess how these fluctuations are associated to psychological distress and well-being both within- and between-day. Ninety-seven Canadian post-secondary students (n = 1581 observations) took part in this study. For 21 consecutive days, they were invited to complete end-of-day diaries (EOD) querying their daily level of distress, well-being and value-based actions. The questionnaires were sent to each student's mobile phone at a random time between 18:00 p.m. and 22:30 p.m. Data were analysed using multilevel modeling and time-lagged analysis. The results show that 1) daily value-based actions were negatively associated with daily distress and positively associated with daily well-being, 2) well-being reported in a given daily diary predicted next-day value-based actions, and 3) greater variability in daily value-based actions was associated with marginally lower daily well-being and steepened increases in daily distress over time.

尽管基于价值的行为通常与改善心理健康的结果有关，但很少有研究在日常水平上探讨这种关系。这项日记研究的目的是探讨基于价值的行为如何随时间变化，并评估这些波动如何与日间和日间心理困扰和幸福感相关。九十七名加拿大大专学生（n = 1581个观测值）参加了这项研究。连续21天，他们被邀请填写日终日记（EOD），​​以查询他们每天的困扰，幸福和基于价值的行动的水平。问卷是在18:00 pm和22:30 pm之间的随机时间发送到每个学生的手机上的。数据使用多层次建模和时滞分析进行了分析。结果显示：1）基于日常价值的行为与日常困扰负相关，与日常健康呈正相关； 2）在给定的每日日记中报告的幸福感预测了基于次日基于价值的行为，以及3）更大每天基于价值的行为的可变性与日后的幸福感略有降低以及随着时间的推移每日困扰的增加急剧增加有关。
