Drinking Problems: Assessed according to the Short Inventory of Problems (Miller, Tonigan, and Longabaugh 1995); Binge Drinking Status: Whether or not participants classified as regular binge drinkers, operationalized according to whether they reported binge drinking on average weekly or more over the past 30 days (see King et al., 2011); Drinking Days: The number of days out of the past 30 participants reported drinking any alcohol; Drinking Quantity: The average number of drinks per occasion participants reported consuming per drinking day in the past 30 days.
All of the above ambulatory models controlled for the presence of other individuals, time of day (evening vs daytime), day of the week (weekend vs. weekday), and lagged mood (i.e., positive or negative mood rating at the prior assessment point). Laboratory models controlled for the order of sessions (alcohol or control session first) as well as pre-drink mood assessed using the PANAS (i.e., positive or negative subscales). Models in table subsection 1 above also control for baseline drinking.
