Note. Dashes represent effects that were dropped from the respective final models for each of the outcome variables. All three-way and Timeline x Moderator interactions were omitted because they were not significant for any model. BAC = blood alcohol concentration; RAPI = Rutgers Alcohol Problems Index; RTCQ = Readiness-to-Change Questionnaire; INCOM = Iowa-Netherlands Comparison Orientation Measure; SSRQ = Short Self-Regulation Questionnaire; TP = Time Perspective.
