In Study 1, at the within-person level, experiencing a stressor earlier in the day predicted a .27 increase in craving that night (R2=.012-.062,p’s<.001; awithin:b=.126-.129-,p=.002; Figure 3). An increase in an individual’s craving relative to their average was associated with a greater probability of the following day being a drinking day(R2=.033,p<.001; bwithin:b=.148,p=.014) and an increase of .43 drinks consumed from their own average levels (R2=.019,p<.001; bwithin:b=.373,p=.008; Figure 4). Although stress did not have a direct effect on the following day’s drinking behavior (cwithin & c’within p’s>.08), the indirect effect via craving was significant at the within-person level (indirectwithin:b=.019-.047,p’s<.001).
