抑制性控制训练是一种新型的心理干预方法，旨在通过联想学习来提高对酒精相关线索的抑制性控制能力。实验室研究表明，与对照/假训练相比，ICT后酒精消耗量减少，但尚不清楚这些影响是否对环境变化具有鲁棒性。在一项预先注册的研究中，我们研究了信息和通信技术的影响是否会在从中性背景到非自然主义酒吧设置的背景转换中幸存下来。在一个混合设计中，60名重度饮酒者（40名女性）被随机分配到一个中立的实验室接受ICT或对照/假训练2个阶段。我们开发了一种新颖的ICT变体，使用多个停止信号来建立直接的刺激-停止关联。ICT/控制的影响进行了测量，一次在相同的背景下，一次转移到一个新的（酒精相关）的背景下。我们的因变量是训练后的随意饮酒，抑制控制过程的变化和酒精值的变化。与对照组相比，ICT在这两种情况下都没有减少酒精摄入量。此外，我们证明了ICT对抑制控制过程或酒精值没有影响。贝叶斯分析证明了对零假设的总体支持。这项研究没有发现ICT对酒精消费或候选心理机制的任何影响。这些发现说明了训练酒精抑制协会的困难，并增加了越来越多的文献表明，信息和通信技术作为酒精使用障碍的心理干预几乎没有证据价值。
Inhibitory control training (ICT) is a novel psychological intervention that aims to improve inhibitory control in response to alcohol-related cues through associative learning. Laboratory studies have demonstrated reductions in alcohol consumption following ICT compared with control/sham training, but it is unclear if these effects are robust to a change of context. In a preregistered study, we examined whether the effects of ICT would survive a context shift from a neutral context to a seminaturalistic bar setting. In a mixed design, 60 heavy drinkers (40 female) were randomly allocated to receive either ICT or control/sham training in a neutral laboratory over 2 sessions. We developed a novel variation of ICT that used multiple stop signals to establish direct stimulus–stop associations. The effects of ICT/control were measured once in the same context and once following a shift to a novel (alcohol-related) context. Our dependent variables were ad libitum alcohol consumption following training, change in inhibitory control processes, and change in alcohol value. ICT did not reduce alcohol consumption in either context compared with the control group. Furthermore, we demonstrated no effects of ICT on inhibitory control processes or alcohol value. Bayesian analyses demonstrated overall support for the null hypotheses. This study failed to find any effects of ICT on alcohol consumption or candidate psychological mechanisms. These findings illustrate the difficulty in training alcohol-inhibition associations and add to a growing body of literature suggesting that ICT holds little evidential value as a psychological intervention for alcohol use disorders.
