The Day Reconstruction Method (DRM) was developed to assess affective states as measures of experienced well-being. The present study aimed to validate an abbreviated version of the DRM in a representative sample of the population in seven countries (China, Ghana, India, Mexico, Russia, South Africa, and Spain), and to examine whether there are country differences in affect and in the relationships among the activities based on the similarity of the affect associated with each of them.
Interviews were conducted with 47,222 non-institutionalized adults from seven countries, using an abbreviated version of the DRM. A cluster analysis was carried out to classify activities on the basis of the similarity of the associated affect. In each country, the factorial structure of the affect adjectives was tested through Confirmatory Factor Analysis. Internal consistency and construct validity were also assessed. Moreover, the differences in affect across countries and the diurnal cycles of affect were evaluated.
The DRM showed adequate psychometric properties regarding reliability and construct validity in all countries. Respondents from Ghana and South Africa reported more positive net affect whereas Indian respondents reported less positive net affect. Most of the countries showed a similar diurnal variation of affect, which tended to improve throughout the day.
The results show that this abbreviated version of the DRM is a useful tool for multi-country evaluation of experienced well-being.
时间重构法（DRM）被开发出来以评估情感状态作为体验幸福感的衡量标准。本研究旨在对来自七个国家（中国、加纳、印度、墨西哥、俄罗斯、南非和西班牙）的代表性人群样本中的 DRM 进行简化版本的验证，并考察在基于与每一种活动相关联的情感的相似性的基础上，这些国家之间的情感和活动之间的关系是否存在差异。
使用 DRM 的简化版本，对来自七个国家的 47222 名非机构化成年人进行了访谈。采用聚类分析根据相关情感的相似性对活动进行分类。在每个国家中，通过验证性因子分析测试情感形容词的因子结构。还评估了内部一致性和构念效度。此外，还评估了各国之间的情感差异和情感的昼夜节律。
DRM 在所有国家的可靠性和构念效度方面都具有良好的心理测量学特性。加纳和南非的受访者报告了更多的积极净情感，而印度的受访者报告了较少的积极净情感。大多数国家的情感昼夜变化相似，全天呈逐渐改善的趋势。
研究结果表明，DRM 的这种简化版本是评估多国体验幸福感的有用工具。
