<p>Understanding the dynamic processes of personality and affect requires
repeated assessments. The experience sampling method (ESM; repeated
measures across a short period of time) is typically held as the gold
standard for such data collection. However, ESM studies are costly,
time-intensive, and more likely than survey research to face attrition.
Alternatively, the day reconstruction method (DRM; asking participants to
detail the events of a previous day) is proposed to provide the same degree
of data richness while circumventing the need for repeated measurements. To
determine if the methods are indeed providing similar information, the
present study of 385 undergraduate students conducted a direct comparison.
Reported affect in the two measures was highly correlated (<em>r</em>s = .76 -
.89), and there was high overall agreement in reported situations (<em>M</em> =
91%). These findings indicate high similarity between ESM and DRM and
support the use of DRM in collecting cross-situation data.</p>
