The Stability of Daily Situation Experiences
How stable are people’s day-to-day lives? It is now well-established that personality traits and behavior are quite stable over time (Roberts & DelVecchio, 2000). Several theories of personality suggest that the stability of one’s environment contributes to the stability of personality. However, little is known about the extent to which features of people’s daily environments are stable. In this secondary analysis, I examined the rank-order stability of individual differences in features of daily situations in a 2-year longitudinal study of daily life (N = 387). I analyzed three waves of two-week Experience Sampling Method (ESM) assessments of daily situation experiences, personality states, and behavior. ESM open responses were also coded for the DIAMONDS characteristics in the first two waves of ESM assessment. Personality states were found to be stable from year-to-year (M Stability = .63). Situated experiences (e.g., familiarity) were found to be about as stable as personality states. Activities (e.g., at home) and the eight DIAMONDS characteristics were found to be less stable than personality and situated experiences, but still showed moderate stability. These findings suggest that situation experience may be a viable individual difference and that the stability of environments may contribute to the stability of behavior, and vice versa.
