Note. The analytic sample for this model included 124 people and 1,641 days. We controlled for age, sex (male = 1, female = 0), weekend/weekday, week in study, and month as covariates in all but 1 model. Month of year and week in study were dropped in the # of drinks normative perceptions analysis due to convergence.
