Self-Knowledge and Correlated Change of State and Trait Personality: A Longitudinal Study

Personality change research has mainly relied on self-reported "trait" measures that assume respondents have self-knowledge. Doubts about self-knowledge underlie a recent push for "state" measures (e.g. ESM). Using 7 waves of trait and 3 waves of state personality ratings, we assess whether trait and ESM measures capture personality change similarly.
