Alcohol consumption has been a growing concern at U.S. colleges, particularly among first-year students, who are at increased risk for problems. This study tested the efficacy of the "electronic Check-Up to Go" (e-CHUG), a commercially-available internet program, at reducing drinking among a group of at-risk college freshman.
The design was a randomized controlled trial: 106 freshmen students who reported heavy episodic drinking were randomly assigned to receive feedback or to assessment only. Assessment measures were completed at baseline, 8 weeks, and 16 weeks.
At 8 weeks, the feedback group showed a significant decrease in drinks per week and peak BAC over control. By 16 weeks, the control group also declined to a point where there were no differences between groups. Changes in normative drinking estimates mediated the effect of the intervention. An additional 245 abstainers and light drinkers who were also randomized to condition did not show any intervention effect.
This study provides preliminary support for the efficacy of this intervention at reducing short-term drinking among at-risk students.
在美国各高校,饮酒问题日益受到关注,尤其是在一年级学生中,他们面临问题的风险更高。本研究测试了“电子自助体检”(e-CHUG)这一商业互联网程序在减少一组有风险的大学新生饮酒量方面的效果。
采用随机对照试验设计:106名报告有大量饮酒情况的新生被随机分配接受反馈或仅接受评估。评估措施在基线、8周和16周时完成。
在8周时,反馈组与对照组相比,每周饮酒量和最高血液酒精浓度显著降低。到16周时,对照组也下降到两组之间没有差异的程度。规范饮酒估计值的变化介导了干预效果。另外245名同样被随机分组的戒酒者和轻度饮酒者未显示出任何干预效果。
本研究为该干预措施在减少有风险学生短期饮酒方面的效果提供了初步支持。
