Abstract
The aim of the present study was to conduct a preliminary investigation of the associations between facets of impulsivity and alcohol outcomes through motives for drinking responsibly described by self-determination theory among college students. Participants (N=2,808) were part of a multisite investigation of college student drinking across 10 universities in 8 states in the U.S. who reported past-month drinking. Results of a structural equation model testing all possible indirect associations simultaneously indicated that one-third (20 out of 60) of the indirect associations were statistically significant (p<.01). Facets with higher scores representing higher impulsivity (negative/positive urgency) were negatively associated with more internalized motives (autonomous motivation and introjected regulation) and positively associated with less internalized motives (external regulation and amotivation) for drinking responsibly. Facets with higher scores representing lower impulsivity (perseverance and premeditation) demonstrated opposite patterns of associations with motives for drinking responsibly. In turn, more internalized motives were related to higher frequency of protective behavioral strategies use, lower alcohol use severity, and fewer negative alcohol-related consequences; less internalized motives demonstrated an opposite pattern of associations with these alcohol outcomes. The present findings should be replicated using experimental and longitudinal studies for appropriately testing mediation but offer support for a novel hypothesis for motivational pathways from impulsivity to alcohol outcomes that may provide insight into intervention targets.
期刊介绍:
Since being founded in 1993, Addiction Research and Theory has been the leading outlet for research and theoretical contributions that view addictive behaviour as arising from psychological processes within the individual and the social context in which the behaviour takes place as much as from the biological effects of the psychoactive substance or activity involved. This cross-disciplinary journal examines addictive behaviours from a variety of perspectives and methods of inquiry. Disciplines represented in the journal include Anthropology, Economics, Epidemiology, Medicine, Sociology, Psychology and History, but high quality contributions from other relevant areas will also be considered.
