Abstract

OBJECTIVES: We examined daily associations between drinking intentions and drinking behaviour and tested past drinking behaviour and current social environment as potential moderators of the daily intention-behaviour association. We expected both more frequent past drinking and being in a high drinking environment to weaken the intention-behaviour association. We also tested intentionality as a moderator of the association between alcohol consumption and next-day negative outcomes, expecting that less intentional alcohol consumption would be related to greater stress and regret.

DESIGN: We tested these hypotheses using two separate micro-longitudinal studies of college students (Ns = 1,641, 540).

METHODS: In two samples, participants completed bursts of data collection in which they indicated their previous alcohol consumption and then completed 30 days of diary surveys in which they reported their alcohol consumption and social environment the previous evening and their levels of stress, regret, and drinking intentions that day.

RESULT: Consistent with our predictions, drinking intentions more strongly predicted drinking behaviour among individuals with less frequent past drinking behaviour, and, in Sample 1, drinking intentions more strongly predicted drinking behaviour among individuals in a low drinking environment. Contrary to hypotheses, results indicated that individuals with low drinking intentions were more likely to experience stress the next day, particularly if they consumed less alcohol. Greater consumption, however, was related to greater odds of experiencing regret, but this was stronger among individuals with higher drinking intentions.

CONCLUSIONS: Findings are discussed in terms of the complex interplay between intentions and both social environment and contextual factors with respect to predicting drinking level and related problems.
