Notes: N = 1,099; all predictors other than gender were grand-mean-centered; gender was dummy coded (0 = men, 1 = women); Cohen’s 
; the regression models used generalized linear models with a negative binomial log link for all outcome variables other than cravings; the regression model for the cravings variable used ordinary least squares regression. No. = number; Facebook self = score on self component (Component 1) of Facebook posting measure; Facebook friend = score on friend-component (Component 2) of Facebook posting measure; RAPI = Rutgers Alcohol Problem Index; AUDIT = Alcohol Use Disorders Identification Test.
