Objective: College drinking is a significant individual and societal problem, and thus, identifying risk factors to alcohol-related problems has been an important line of inquiry. Adding to this rich literature, the current study examined whether perfectionism dimensions were associated with alcohol-related problems and whether a poor self-regulation process linked these associations. Participants: A total of 410 university students completed measures pertaining to perfectionism, procrastination, and negative consequences of alcohol use. Methods: Parallel mediation models were tested. Results: There was support for an indirect effect in the association between perfectionistic concerns and alcohol-related problems through susceptibility to temptation but not through pure procrastination or irrational procrastination. Perfectionistic strivings dimension was not associated with alcohol-related problems and this relation was not mediated by any procrastination dimensions. Conclusions: Building internal resources to better resist immediately gratifying yet long-run detrimental behavioral habits is important, especially so for highly self-critical students.
