The study of well-being is becoming a priority in social sciences. The Day Reconstruction Method (DRM) was developed to assess affective states. The aim of the present study was to validate an abbreviated version of the DRM designed for administration in population studies, and to assess its test-retest properties.
1560 adults from Jodhpur (India) were interviewed using an abbreviated version of the DRM, and a week later they were re-interviewed using the original long version of the DRM, after which the abbreviated version of the DRM was compared with the original version. A regression model considering interaction terms was employed to analyse the impact of sociodemographic characteristics on net affect. Test-retest reliability was assessed, and found to be moderate. Positive affect showed more test-retest reliability than negative affect, while net affect had more temporal stability than U-index. The affect of sets A, B, and C, taken together, had a moderate predictive ability compared with the affect obtained using the full version of the DRM: AUC = 0.67 for positive affect; 0.66 for net affect; 0.61 for negative affect; and 0.60 for the U-index. Household income, gender, and setting all had a significant impact on net affect.
Net affect and positive affect showed moderate temporal stability, whereas negative affect and the U-index showed fair temporal stability. Evaluating the affective state using the abbreviated version of the DRM provides a profile of the population similar to that of the full version. The results provide considerable support for using the short version of the DRM as an instrument to measure subjective well-being in large population surveys.
幸福感研究正成为社会科学的一个重点。时间重构法（DRM）是为评估情感状态而开发的。本研究的目的是验证一种为人群研究设计的 DRM 缩写版，并评估其重测信度。
来自印度焦特布尔的 1560 名成年人接受了 DRM 缩写版的访谈，一周后，他们使用 DRM 的原始长版本进行了重新访谈，然后将 DRM 的缩写版与原始版本进行比较。采用考虑交互项的回归模型来分析社会人口特征对净影响的影响。评估了重测信度，发现其为中度。正性情绪的重测信度高于负性情绪，而净影响的时间稳定性高于 U 指数。综合考虑 A、B 和 C 集的影响，与使用 DRM 完整版本获得的影响相比，具有中度预测能力：正性影响的 AUC 为 0.67；净影响的 AUC 为 0.66；负性影响的 AUC 为 0.61；U 指数的 AUC 为 0.60。家庭收入、性别和环境对净影响均有显著影响。
净影响和正性影响具有中度的时间稳定性，而负性影响和 U 指数具有良好的时间稳定性。使用 DRM 缩写版评估情感状态可以提供与完整版本相似的人群概况。这些结果为使用 DRM 短版本作为测量主观幸福感的工具在大型人群调查中提供了充分的支持。
