Note. Bolded rows indicated significant effects; alpha = .034. B = unstandardized parameter estimate, log-linked for truncated negative binomial regression of alcohol consumed (ml); SE = standard error of the parameter estimate; eB = exponentiated coefficient also known as the Incident Rate Ratio; LL95% and UL95% = lower and upper limits of 95% confidence intervals. Weekly consumption equals total typical weekly alcohol consumption in US standard drinks as reported on the Daily Drinking Questionnaire. Gender was coded 0 = male, 1 = female. Video condition = exposure to either happy/neutral (Muppets or Denali) or sad (Schindler’s List) video clip. Predictors were mean centered prior to creation of product terms.
