近年来的研究表明，更加细致的情感标签与更强的心理健康之间存在关联，并且文化可能会在个体差异层面上影响这种关联。因此，本研究基于中美两国不同文化参与者的数据，通过考察文化如何影响个体对情感体验的认知和对情绪词汇选择的精确度，分析这些因素与心理健康的相关性。研究通过两项在线实验，使用情景评定任务评估情绪细粒度，并使用三种自我报告量表（GAD-7、PHQ-9、TAS-20）评估焦虑、抑郁和述情障碍。研究一发现文化因素的影响显著，例如在负性情绪细粒度方面，美国参与者的负性情绪细粒度与心理健康测量之间存在显著的负相关性，而在中国参与者中则表现为较弱的正相关性。研究二则通过为期7天的情绪细粒度干预追踪调查发现，干预未对参与者的情绪细粒度和三项心理健康指标产生显著的影响，量表结果显示两个文化群体之间产生了显著的差异；在单独按照干预时间点和国别进行调节分析时，积极情感粒度在所有时刻均与述情障碍存在显著的交互效应，并且在T2时刻与焦虑产生显著的交互效应。研究结果表明，文化因素显著影响个体的情绪细粒度，并对情绪细粒度与其他心理健康指标的相关性产生影响。这些发现为探索不同文化背景下的情绪细粒度干预措施提供了宝贵的见解，有助于提升个体的心理健康和整体生活质量。

Growing selections of research identify the presence of associations between finer grained emotional labeling with better well-being, and suggest the potential presence of cultural influences on the presentation of individual differences in emotional granularity and well-being: recommending their exploration. Through sampling both Chinese and American participants, this study aims to contribute to our understanding of the intricate ways culture may shape individuals’ cognition of affective experiences, the precision of emotional terms chosen, correlations with mental health; and the efficacy of emotional granularity interventions in improving mental health outcomes. Two online studies were employed, with emotional granularity assessed through the Scenario Rating Task and anxiety, depression, and alexithymia through three self-report measures (GAD-7, PHQ-9, TAS-20). Study 1 found a presence of cultural influences on emotional granularity and correlations with mental health; especially concerning negative emotional granularity where it was consistently strongest and negatively correlated with the mental health measures among American participants, but only weakly positively correlated with Chinese. Cultural influences were further explored in Study 2 where a 7-day emotional granularity intervention was used. While the intervention produced no significant overall effects to participant’s emotional granularity, nor the three mental health measures; significant differences across all five measures between the two cultural cohorts was observed. Assessed both isolated by time point and country, significant interaction effects were also revealed during moderation analysis of positive emotional granularity with both alexithymia when assessed for time with only Chinese participants, and with anxiety when assessed for country at T2. The results of this study demonstrate the presence of cultural influences on individual’s emotional granularity, alongside impacts of its correlations with the other mental health measures. These findings offer valuable insights for developing culturally sensitive interventions that could enhance individuals‘ mental well-being and overall quality of life.
