The impact of defensiveness and incident reactions on post-sanction drinking behaviors among mandated students

• We examine drinking changes after a sanction but before clinical intervention.
• Students significantly decreased alcohol quantity and frequency post-sanction.
• Heavier drinkers high in defensiveness had higher post-sanction drinking quantities.
• Heavier drinkers low in aversiveness had higher post-sanction drinking quantities.

IntroductionPrior studies with mandated students (students referred for an intervention following violation of a campus alcohol policy) have suggested that decreases in drinking behaviors may occur before clinical intervention. Others studies have suggested that greater reductions were associated with lower defensiveness and stronger incident reactions, such as responsibility and aversiveness. The current study sought to integrate these findings and examine the influence of pre-sanction drinking and perceptions on mandated students' post-sanction drinking levels prior to attending a brief intervention.MethodsData were collected as part of a longitudinal study of brief interventions in a mandated student sample (N = 61, 43% female, 97% White). Participants completed demographic measures, scales measuring incident reactions and defensiveness, and a Time Line Follow Back assessing drinking quantity and frequency both pre- and post-sanction.ResultsAnalyses revealed significant post-sanction decreases in quantity (average total drinks per month) and frequency (number of monthly drinking days). Pre-sanction drinking quantity and frequency significantly predicted post-sanction quantity and frequency, respectively. Interaction effects suggest higher post-sanction quantities among moderate and heavier drinkers with higher defensiveness and lower aversiveness perceptions, while perceptions did not influence outcomes among light drinkers. None of the interactions involving blame or responsibility, or predicting post-sanction frequency, were significant.ConclusionsThese findings suggest a complex relationship between pre-sanction drinking and student reactions. Implications for mandated student interactions and future research directions are discussed.
