creator Grix, Bethany advisor Mitchell, M. Ellen Binge-drinking among young adult populations is considered a global health and safety concern. Binge-drinking behavior has been directly linked to immediate and long-term psychosocial, societal, and health-related consequences. To date, psychological flexibility and values-based committed action has been only theoretically linked to binge-drinking behavior, health, and alcohol-related consequences. Therefore, this study investigated binge-drinking behavior and its relationship with alcohol and health-related consequences, in a college-aged population, as well as the role psychological flexibility has within these relationships. Binge-drinking was defined as the consumption of ≥ 4/5 drinks (females/males, respectively), within a two hour period, over a 6-month period (NIAAA, 2004; Courney & Polnich, 2009). One hundred eighty-nine undergraduate participants (75 female, 114male) from a Midwestern university completed an online survey. Of the 189 undergraduates, 116 (61.4%) identified as non-binge-drinkers and 73 (38.6%) as binge-drinkers. Results showed that psychological flexibility predicted binge-drinking behavior. More specifically, higher degrees of psychological flexibility decreased the likelihood that individuals would engage in binge-drinking behavior. Interactions also emerged between binge-drinking quantity and psychological flexibility on alcohol-related consequences. Similarly, psychological flexibility was shown to buffer the relationship between binge-drinking status and HRQoL. Demographic and psychosocial differences also emerged across binge-drinking severity groups and outcome measures.
