Self-Other Agreement in Experience Sampling Measures

Experience sampling methodology (ESM) has provided researchers with a flexible and innovative measurement tool, and the methodology has become increasingly popular in several fields of psychology. Therefore, validity studies on such measures are important. The present study investigated convergent and discriminant validity of ESM measures using peer-ratings as the criteria. We obtained ESM self- and other-ratings of personality states, situation perceptions, and feelings from 344 occasions, from 49 target participants. The results showed that several-but not all-widely used ESM self-ratings have substantial and distinct self-other agreement. We conclude that many ESM self-reports are likely to capture, at least to an extent, target persons' actual personality states, feelings, and situation perceptions.
