Abstract
BACKGROUND: Young adulthood is a high-risk period for heavy drinking and binge eating, both of which can impact weight and lead to obesity. Examining motives for drinking alcohol and eating palatable foods may facilitate a more integrated understanding of these behaviors during the college years. The current study tested whether shared or distinct (i.e., behavior-specific) motivational mechanisms may explain the occurrence of reward-driven drinking and eating in young adults. METHODS: A sample of college freshmen (N = 103) stratified by sex, race/ethnicity, and heavy drinking status were selected to participate. Participants completed questionnaires measuring alcohol use, eating behavior, and motives assessed by the Drinking Motives Questionnaire-Revised and Palatable Eating Motives Scale. Confirmatory factor analysis (CFA) tested whether drinking and eating motives were better represented as single latent motives, or two behavior-specific motives. Structural equation modeling (SEM) was used to test the association between motivational factors and behaviors. RESULTS: Behavior-specific CFA models demonstrated stronger model fit and higher factor loadings than single motive models. SEM models indicated that eating to cope with negative emotions, to enhance positive experiences, to obtain social reinforcement, and to conform with peers were significantly associated with binge eating (p values < .001). Enhancement and social drinking motives were significantly associated with number of weekly drinks (p values < .001). CONCLUSIONS: While motives for drinking alcohol and eating palatable foods may satisfy common goals, findings suggest motivational mechanisms may be behavior-specific. Enhancement and social motives may be important factors to target in prevention programs for both drinking and binge eating.
