Across the five days of pre-randomization data collection for this study there were a total of 262 Begin Drink 1 Reports, 259 End Drink 1 Reports, 223 Begin Drink 2 Reports, and 223 End Drink 2 Reports. This resulted in a total of 259 complete drink 1 reports (Begin Drink 1 + End Drink 1) and 223 complete drink 2 reports (Begin Drink 1 + End Drink 1 + End Drink 2). Only 36 drinking episodes consisted of a single drink whereas the remaining 223 episodes consisted of two drinks. Participants reported an average of 2.31 drinking episodes over the 5-day assessment period. Morning Report data for the five days period were culled for the purpose of this study and revealed that participants reported consuming an average of 4.67 (SD = 5.45) drinks per drinking episode, of which the first two drinks were captured via EMA assessments and represent the focus of this report.
