Abstract

In recent years, the focus on mental health care in Japan has increased, leading to a rise in companies addressing employee mental well-being. Chronic stress, stemming from various sources including work and interpersonal relationships, can have severe impacts on individuals’ happiness and health. To address this, there is a growing demand for technology capable of measuring chronic stress on a daily basis. In this study, we explore the potential of using facial thermal images (FTI) as a method for daily measurement of chronic stress. We conducted experiments over a 3-month period with healthy adult participants, collecting routine data on chronic stress and capturing FTI. Independent component analysis (ICA) was applied to the FTI data to extract relevant features. In addition, psychological questionnaires were administered to assess chronic stress levels. We aggregated the questionnaire scores using principal component analysis (PCA) to obtain a single chronic stress indicator. Multiple regression analysis (MRA) was then employed to model the relationship between the extracted FTI components and chronic stress scores. Our results indicate a moderate to strong correlation between the predicted and actual chronic stress scores, suggesting the potential utility of FTI in estimating stress levels. Identified features in the FTI, particularly around the upper lip and on the right half of the face, showed significant associations with chronic stress. This study provides insights into the feasibility of using FTI as a non-invasive method for daily monitoring of chronic stress levels. However, limitations such as variations in stress levels among participants and questionnaire administration frequency should be considered in future research.

用于慢性压力评估的面部热图像回归分析
近年来,日本对心理健康护理的关注度不断提高,从而导致越来越多的公司开始关注员工的心理健康。来自工作和人际关系等不同方面的慢性压力会严重影响个人的幸福和健康。为解决这一问题,对能够测量日常慢性压力的技术的需求日益增长。在本研究中,我们探索了使用面部热图像(FTI)作为日常测量慢性压力的方法的潜力。我们对健康的成年参与者进行了为期 3 个月的实验,收集慢性压力的常规数据并捕捉 FTI。我们对 FTI 数据进行了独立成分分析(ICA),以提取相关特征。此外,我们还进行了心理问卷调查,以评估慢性压力水平。我们使用主成分分析法(PCA)对问卷得分进行汇总,以获得单一的慢性压力指标。然后,我们采用多元回归分析(MRA)对提取的 FTI 成分与慢性压力得分之间的关系进行建模。我们的结果表明,预测的慢性压力得分与实际的慢性压力得分之间存在中度到高度的相关性,这表明 FTI 在估计压力水平方面具有潜在的实用性。在 FTI 中识别出的特征,尤其是上唇周围和右半边脸的特征,显示出与慢性压力的显著关联。这项研究为使用 FTI 作为日常监测慢性压力水平的非侵入性方法的可行性提供了启示。然而,在未来的研究中应考虑到参与者之间压力水平的差异和问卷发放频率等局限性。
