IntroductionExisting research highlights the significance of prosocial behavior (voluntary, intentional behavior that results in benefits for another) to people's well‐being. Yet, the extent to which this expected positive relation operates at the within‐person level (e.g., is more prosocial behavior than usual related to a higher than usual level of well‐being?) while taking into account stable interindividual differences, remains a research question that deserves further investigation. In this study, we aimed to explore the relations between prosocial behavior and hedonic (HWB; subjective assessment of life satisfaction and happiness) and eudaimonic (EWB; actualization of human potential in alignment with personal goals, including concepts like meaning in life and closeness to others) well‐being in daily life.MethodUsing ecological momentary assessment for 4 weeks, data were collected from two British samples, comprising 82 adolescents and 166 adults.ResultsDynamic Structural Equation Modeling revealed a positive relations between prosocial behavior and HWB/EWB at both between and within‐person levels across the samples.ConclusionIn summary, these findings further support the positive link between prosocial behavior and well‐being in everyday life. Notably, this association was consistent across different age groups (adolescent and adults) at both between and within‐person levels.

日常生活中亲社会行为、享乐和幸福之间的关系


简介现有的研究强调了亲社会行为（为他人带来利益的自愿、有意的行为）对人们福祉的重要性。然而，在考虑稳定的个体差异的同时，这种预期的积极关系在人体内发挥作用的程度（例如，比平常更多的亲社会行为是否与高于平常的幸福水平相关？），仍然是一个研究值得进一步研究的问题。在这项研究中，我们旨在探讨亲社会行为与享乐（HWB；对生活满意度和幸福的主观评估）和幸福（EWB；根据个人目标实现人类潜力，包括生活意义和亲近感等概念）之间的关系。方法采用为期 4 周的生态瞬时评估，从两个英国样本中收集数据，其中包括 82 名青少年和 166 名成年人。结果动态结构方程模型揭示了亲社会行为与 HWB/EWB 之间存在正相关关系。结论总而言之，这些发现进一步支持了亲社会行为与日常生活中的幸福感之间的积极联系。值得注意的是，这种关联在不同年龄组（青少年和成人）中在人与人之间和人内水平上都是一致的。
