Note. Between-person correlations are presented below the diagonal. Within-person correlations between the daily measures are presented above the diagonal. All p values are two-sided p values. For all daily measures, we extracted the mean (intercept) and standard deviation from the multilevel null model of the respective variable.

^aN differed between momentary mood and state extraversion because of the “not applicable” response option in state extraversion. ^bN differed because the respective variables were assessed on different measurement occasions.
