Note. n observations analyzed = 468. OR = odds ratio. Level-1 effects = within-person; Level-2 effects = between-person. Reference group for outcome is unplanned (vs. planned) drinking. All data were drawn from the daily diary report. Intraclass correlation coefficient (ICC) = 0.10, which indicates 10% of the variance in the outcome is at the between-person level (Singer, 1998; Sommet & Morselli, 2017). Level-1 effects are person-mean centered. Level-2 effects are grand- mean centered.
