EMA = ecological momentary assessment; CI = 95% confidence interval; between = between-subjects effect (grand-mean centered variable); within = within-subjects effect (person-mean centered variable. Gender was coded such that men were the reference category. Each dependent variable was aggregated within day to represent the daily mean of the variable.
