Understanding profiles of student binge drinking and eating: The importance of motives.

摘要: Abstract Binge drinking and binge eating occur frequently in undergraduates; however, the mechanism driving their co-occurrence is not well-understood. Several theories support role of motives behavior, especially motivations related to affect regulation (i.e., enhancement/pleasure coping). This study used a person-centered approach identify classes students based on past-month behavior examined class differences psychopathology, emotion regulation, impulsivity. Undergraduates (N = 776) completed timeline follow-back surveys assessing motives, eating, impulsivity, quality life. Mixture modeling was group presence/absence drinking, for drinking. The analysis resulted 4 classes: Drinking (with relatively high social enhancement motives), Eating overall Both Bingeing coping, Low low both behaviors). ANOVA post-hoc analyses suggested that groups were most impaired, while rarely differed from across measures psychological distress. Notably, with eating/drinking displayed significant impairment despite all members endorsing behavior. Findings suggest addition may imply more importance among undergraduates potentially trying challenge these through early intervention.
