成瘾的双过程模型表明，酒精相关认知的影响可能依赖于执行功能的水平。本研究探讨了内隐和外显酒精相关认知和工作记忆容量之间的相互作用是否可以预测高危青年在一个月后的酒精使用。内隐和外显酒精相关的认知进行了评估，在88个荷兰的风险青少年，年龄从14岁到20岁（51名男性）的改编版本的内隐联想测试（IAT）和预期问卷。工作记忆容量使用基于计算机的版本的自我排序指向任务（SOPT）进行评估。在基线和一个月后用自我报告问卷测量酒精使用和酒精相关问题。分层回归分析表明，无论是内隐的正唤醒认知和工作记忆容量之间的相互作用和外显的正唤醒认知和工作记忆容量之间的相互作用预测独特的方差在饮酒后1个月。内隐积极唤醒认知预测酒精使用后一个月更强烈的工作记忆能力水平较低的学生，而外显积极唤醒认知预测1个月的后续酒精使用更强烈的工作记忆能力水平较高的学生。这可能意味着不同的干预方法可能对不同的高危青少年亚群有效。(c)2007爱思唯尔爱尔兰有限公司保留所有权利。
Dual process models of addiction suggest that the influence of alcohol-related cognition might be dependent on the level of executive functioning. This study investigated if the interaction between implicit and explicit alcohol-related cognitions and working memory capacity predicted alcohol use after I month in at-risk youth. Implicit and explicit alcohol-related cognitions were assessed in 88 Dutch at-risk adolescents ranging in age from 14 to 20 (51 males) with an adapted version of the Implicit Association Test (IAT) and an expectancy questionnaire. Working memory capacity was assessed using the computer-based version of the Self-Ordered Pointing Task (SOPT). Alcohol use and alcohol-related problems were measured at baseline and after I month with self-report questionnaires. The hierarchical regression analysis showed that both the interaction between implicit positive-arousal cognitions and working memory capacity and the interaction between explicit positive-arousal cognitions and working memory capacity predicted unique variance in alcohol use after I month. Implicit positive-arousal cognitions predicted alcohol use after I month more strongly in students with lower levels of working memory capacity, whereas explicit positive-arousal cognitions predicted 1-month follow-up alcohol use more strongly in students with higher levels of working memory capacity. This could imply that different intervention methods could be effective for different subgroups of at-risk youth. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
