  1. Moderator was probed at the 16th, 50th, and 84th total sample percentile of alcohol problem severity factor using the pick-a-point approach to determine the conditional indirect effect of intervention condition on follow-up drinks per day through changes in motivation after accounting for corresponding baseline motivation and drinking; beta estimates are unstandardized
  2. *Denotes significant conditional indirect effect
