Annotation
A sample of 614 young men and women were followed in a longitudinal study to determine the effect of personality on problems from drinking alcohol. Three possible explanations were explored involving mediating, moderating, and direct-effect models. The study hypothesized that personality would have both direct and moderating effects on drinking problems and DWI.
Abstract
The results supported the existence of both direct and moderating predictive effects of personality on drinking problems and confirmed that personality and other risk factors do not simply influence drinking problems by affecting consumption alone. The existence of direct effects was strongly supported for only one of the personality dimensions -- Cognitive Motivation. These effects were replicated across gender and other dependent variables. Future research should address the relationship between self-report judgments and traditional conceptions of expectancy as a memory process. 5 tables and 69 references
