Implementation intention formation, which involves identifying triggers and linking them with coping strategies, has proven effective at reducing alcohol consumption in general populations. For the first time, the present study tested the ability of implementation intentions to reduce alcohol consumption among heavy drinkers and to explore potential neuropsychological mechanisms. At baseline, participants were randomized to form implementation intentions or to an active control group. There was a 5.7 unit (1 unit = 10 ml or 8 g ethanol) per week reduction ([95%CI 0.15, 11.19], p = 0.048) in alcohol consumption at 1 month follow-up among participants who formed implementation intentions, which was significantly more than controls F(1, 91) = 3.95, p = 0.048, a medium effect size (d = 0.47, Cohen, 1992). No significant differences in performance on the neuropsychological tasks were found between groups. The present study demonstrates for the first time that implementation intentions reduce alcohol consumption among heavy drinkers.
实施意向形成，涉及识别触发因素并将其与应对策略联系起来，已被证明在减少普通人群的酒精摄入量方面非常有效。本研究首次测试了实施意向减少重度饮酒者饮酒量的能力，并探讨了潜在的神经心理学机制。在基线时，参与者被随机分配制定实施意向或积极对照组。在 1 个月的随访中，制定实施意向的参与者每周的酒精摄入量减少了 5.7 个单位（1 个单位=10ml 或 8g 乙醇）（[95%CI 0.15, 11.19]，p=0.048），与对照组相比差异有统计学意义（F(1, 91)=3.95，p=0.048，中等效应大小（d=0.47，Cohen，1992）。两组在神经心理学任务上的表现无显著差异。本研究首次证明，实施意向可以减少重度饮酒者的饮酒量。
