Noncompliance with the monitoring protocol (e.g., not entering drinks in real-time) may threaten the validity of the EMA data and there is no way to ensure that all drink reports used in analysis were completed at the appropriate time. However, three methods were used to increase the probability that the drink reports included in this study were valid. First, we included a question in a ‘Morning Report’ that asked the participant if he/she had forgotten to enter any drinks the previous day. On only 3.9% of days did participants endorse failing to enter drinks. Second, participants were asked in the Begin and End Drink Reports to indicate how long after the beginning, or end, of the drink the assessment was initiated.

Further, we identified participants who were noncompliant with other aspects of the study. It might be expected that these participants would also be noncompliant with the drink reports. Poor compliance was operationally
