The current study aimed to test for potential interactive effects of three implicit alcohol-related associations (drinking identity, alcohol approach and alcohol excitement) in predicting concurrent and prospective alcohol consumption and risk of alcohol use disorders (AUDs) in two samples of the US undergraduate drinkers and non-drinkers.
We investigated the independent and interactive effects of three implicit associations on alcohol consumption and risk of AUD in two US undergraduate student samples. We found that implicit associations had independent but not interactive effects on concurrent and subsequent alcohol consumption and risk of AUD in two independent samples.
Implicit drinking identity, alcohol approach and alcohol excitement associations were assessed in two US undergraduate student samples (Sample 1: N = 300, 55% female; Sample 2: N = 506, 57% female). Alcohol consumption and risk of AUD were assessed at baseline (Samples 1 and 2) and 3 months later (Sample 2). We fit zero-inflated negative binomial models to test for independent and interactive effects of the three implicit associations on alcohol consumption and risk of AUD.
Although we found multiple, unique main effects for alcohol associations, we found minimal evidence of interactions between implicit alcohol-related associations. There was no reliable evidence of interactions in models in predicting alcohol consumption or risk of AUD, concurrently or prospectively, in either sample.
Contrary to expectations, results from both studies indicated that implicit alcohol-related associations in the US undergraduate samples generally have independent, not interactive, relationships with alcohol consumption and risk of AUD.
本研究旨在测试三种与酒精相关的内隐联想（饮酒身份、对酒精的趋近以及酒精兴奋感）在美国本科饮酒者和非饮酒者的两个样本中，对同时期和前瞻性酒精消费以及酒精使用障碍（AUDs）风险的潜在交互作用。
我们调查了三种内隐联想在美国本科学生的两个样本中对酒精消费和AUD风险的独立及交互作用。我们发现，在两个独立样本中，内隐联想对同时期及后续酒精消费和AUD风险具有独立而非交互的作用。
在美国本科学生的两个样本（样本1：N = 300，55%为女性；样本2：N = 506，57%为女性）中评估内隐饮酒身份、对酒精的趋近以及酒精兴奋感联想。在基线期（样本1和样本2）以及3个月后（样本2）评估酒精消费和AUD风险。我们采用零膨胀负二项模型来测试三种内隐联想对酒精消费和AUD风险的独立及交互作用。
尽管我们发现了酒精联想的多个独特主效应，但我们发现内隐酒精相关联想之间相互作用的证据极少。在任何一个样本中，无论是同时期还是前瞻性地预测酒精消费或AUD风险的模型中，都没有可靠的相互作用证据。
与预期相反，两项研究的结果均表明，美国本科样本中的内隐酒精相关联想通常与酒精消费和AUD风险存在独立而非交互的关系。
