This paper introduces Impulsive Decision Reduction Training (IDRT) as a "proof of concept" in terms of its feasibility and preliminary outcome associations. IDRT is a novel, manualized, 8-week intervention designed to reduce impulsive and risky decisions regarding alcohol consumption and reduce excessive drinking. We conducted a pilot study of IDRT in young adult college students who binge drink, comparing IDRT with a waitlist control condition. Twenty-five participants (13 women, 12 men) completed the 8-week IDRT intervention and were compared with 20 (6 women and 14 men) who completed the assessments in the waitlist control group. IDRT was well-received (rated as very helpful), with all sessions attended, and only one IDRT participant dropping out after 3 sessions. Three waitlist control participants did not show up for the additional assessments after their initial baseline assessment. IDRT was associated with significant and large increases in future orientation and the consideration of the consequences of decisions (ps < 0.001). IDRT also associated with significant but modest reductions in the frequency of drinking (p < 0.05) and the maximum number of drinks consumed (p < 0.05), but not in the average quantity of alcohol consumed in an occasion or delay discounting rates, compared to a waitlist control condition. IDRT shows some initial promise as an intervention targeting reductions in impulsive and risky drinking decisions and reducing excessive drinking. Formal clinical trials should be conducted to more comprehensively assess the effectiveness of IDRT in reducing excessive drinking.
本文介绍了冲动决策减少训练（IDRT），就其可行性和初步结果关联而言，这是一种“概念验证”。IDRT是一种新颖的、手册化的为期8周的干预措施，旨在减少与饮酒相关的冲动和冒险决策，并减少过度饮酒。我们对经常暴饮暴食的年轻成年大学生进行了IDRT的试点研究，将IDRT与等待名单对照组进行比较。25名参与者（13名女性，12名男性）完成了为期8周的IDRT干预，并与20名（6名女性和14名男性）在等待名单对照组中完成评估的参与者进行了比较。IDRT受到了好评（被评为非常有帮助），所有课程都有人参加，只有一名IDRT参与者在3次课程后退出。3名等待名单对照组的参与者在初始基线评估后没有参加额外的评估。IDRT与未来导向以及对决策后果的考虑显著且大幅增加相关（p < 0.001）。与等待名单对照组相比，IDRT还与饮酒频率显著但适度降低（p < 0.05）以及饮酒量最大值显著降低（p < 0.05）相关，但与单次饮酒的平均酒精量或延迟折扣率无关。IDRT作为一种旨在减少冲动和危险饮酒决策以及减少过度饮酒的干预措施显示出一些初步的前景。应进行正式的临床试验，以更全面地评估IDRT在减少过度饮酒方面的有效性。
