Note. Four-month count-based analyses are displayed in the section following the rows pertinent to the “Relapse to 3 consecutive days drinking” outcome. Analyses for all 4-month count-based outcomes use a Poisson negative binomial regression as a means of accounting for a high number of zero cases and overdispersion of the distribution. CBT = cognitive behavioral therapy; BDAC = Breaking the Drinking and Anxiety Connection; PMRT = Progressive Muscle Relaxation Training.

^ap values shown in bold indicate statistically significant effects.

^bBinge drinking is defined by National Institute on Alcohol Abuse and Alcoholism guidelines as four drinks per drinking episode for women and five drinks per drinking episode for men.

^cThe p value for the group comparison on drinks per month at baseline was based on log-transformed values; however, raw values are shown in the table to facilitate comparison between baseline and the 4-month outcome.
