Predictors of alcohol use prior to deployment in National Guard Soldiers.

Frequent and heavy alcohol use is associated with negative mental and physical health consequences. Previous research has suggested that alcohol misuse is associated with demographic, personality, and mental health variables. This study examined the relative contribution of these factors in predicting drinking among National Guard soldiers prior to deployment to a combat zone. Members of a National Guard Brigade Combat Team (N=515) completed questionnaires assessing drinking behaviors in the past year (frequency, quantity, binge, and total drinking), as well as demographic, personality, and mental health variables. As a group, demographic and personality variables significantly predicted all drinking outcomes. Negative emotionality and disconstraint were independent predictors of all drinking variables. Younger age predicted higher quantity of drinking, while being unmarried predicted greater total drinking and higher frequency of binge drinking. Once the influence of personality variables were accounted for, mental health was not associated with any drinking variable. The results of this study illustrate the role of factors associated with problematic drinking in a sample of high-risk individuals.
