This quasi-experimental field study assessed whether an incentive/reward intervention can change the drinking behavior and the subsequent levels of intoxication among college students attending fraternity parties. A total of 356 blood alcohol concentration (BAC) assessments, using hand-held breathalyzers. were obtained at two baseline and at two intervention parties at the same fratenity house. At the intervention parties, the students were informed they could win a cash prize if their BAC was below .05, and they were given nomograms to aid in monitoring their levels of intoxication. Mean BAC and the percentage of partiers with intoxication levels above .05 were significantly lower at the two intervention parties. More than twice as many partygoers were legally intoxicated (i.e., BAC > .08) at the two baseline parties than at the two intervention parties. indicating a clinically significant impact of the incentive/reward intervention. Greek-life students, in particular, were significantly less intoxicated at intervention parties, compared to baseline parties (p < .001).
这项准实验性实地研究评估了激励/奖励干预措施是否能够改变参加兄弟会派对的大学生的饮酒行为及其随后的醉酒程度。使用手持式酒精测试仪，在同一兄弟会会所的两次基线派对和两次干预派对上共获得了356次血液酒精浓度（BAC）评估结果。在干预派对上，学生们被告知如果他们的BAC低于.05，就可以赢得现金奖励，并且还给他们提供了列线图以帮助监测他们的醉酒程度。在两次干预派对上，平均BAC以及醉酒程度高于.05的派对参与者的百分比显著更低。在两次基线派对上，法定醉酒（即BAC>.08）的参加派对者数量是两次干预派对上的两倍多，这表明激励/奖励干预措施具有临床上的显著影响。特别是，与基线派对相比，联谊会学生在干预派对上的醉酒程度显著更低（p<.001）。
