Expectancy challenges (ECs) were used to change alcohol expectancies and alcohol consumption in young heavy drinking men (age 16-24) on holiday. The intervention took place in community centers and bars. Alcohol expectancies and consumption were assessed with paper and pencil measures prior to the intervention (N=301) and 2 days afterwards (EC: n=178; controls: n=86). Six weeks after the EC, participants were interviewed by telephone (EC: n=163; controls: n=71). The intervention resulted in an increase in sedation expectancies in the EC group. Furthermore, the EC led to a differential reduction in alcohol consumption on a night out at the six-week posttest in the heaviest drinkers only. The reduction in alcohol consumption on a night out was not mediated by the change in sedation expectancies. These findings suggest that further research on the mechanisms of change is necessary before a single-session EC may be used in a real-life prevention setting.
预期挑战（ECs）被用于改变度假期间年轻酗酒男性（年龄16 - 24岁）的饮酒预期和饮酒量。干预在社区中心和酒吧进行。在干预前（N = 301）以及干预后2天（EC组：n = 178；对照组：n = 86），通过纸笔测量评估饮酒预期和饮酒量。在EC干预六周后，通过电话对参与者进行访谈（EC组：n = 163；对照组：n = 71）。干预导致EC组的镇静预期增加。此外，仅在最严重饮酒者中，EC在六周后的后测中导致外出当晚饮酒量有差异地减少。外出当晚饮酒量的减少并非由镇静预期的变化介导。这些发现表明，在单次EC可用于现实生活中的预防环境之前，有必要对变化机制进行进一步研究。
