Nperson = 199; Nobservations=8416. SE = standard error. Stressor Recency refers to self-reported minutes between stressor occurrence and the current survey; period between surveys was 2.5 hours on average. Lagged Stressor refers to the lagged effect of stressor reports at the previous survey, which represents stressors occurring approximately 2.5–5 hours prior to the reports of current NA. The Stressor term in the Random Effects is a binary variable that describes whether a stressor was reported as occurring since the last survey. The reference category for Stressor Recency, Stressor, and Lagged Stressor is No Stressor Reported. This model includes momentary reports of current location, activities, and social partners as controls. For parsimony, these effects are not reported in the table.
