A positive difference indicates a higher score, and a negative difference indicates a lower score in end‐of‐day diary compared with ESM. Mixed linear models with the delta score (i.e., difference between ESM mean or max score and end‐of‐day diary score) as the dependent variable corrected for repeated measures (AR1 covariate structure) were used to test significance. Strength and direction of the association is depicted by estimate.
