The day reconstruction method (DRM) is an approach to measuring well-being that is designed to approximate the rich data that can be obtained from intensive repeated measures designs like those used in the experience sampling method (ESM). Although some preliminary tests of the validity of the DRM have been conducted, these typically focus on agreement between the 2 methods at very broad levels, rather than focusing on whether the 2 methods provide similar information about the exact same moments. This article reports 2 studies that use ESM and DRM to assess the same moments. Agreement between the 2 measures varied considerably depending on the focus of the analysis. For aggregate assessments of total time spent in situations and average affect in situations, agreement was high; for between-person differences in time use and experienced affect, agreement varied across situations; and for within-person differences in both situations and affect, agreement was quite low. In addition, we found preliminary evidence that the DRM may be more influenced by expectations regarding the pleasantness of situations as compared with ESM. These results suggest that for many common purposes, the DRM does not provide the same information as ESM. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
