Introduction

This study examined the associations between alcohol-related cognitions within the social reaction pathway of the Prototype Willingness Model and concurrent (use of two or more substances within a specified time period) use of 1) alcohol and marijuana and 2) alcohol and prescription stimulant misuse.

Methods

A convenience sample of 1,062 emerging adults in the U.S. (18–20 years old; 54.5% female) who reported past 3-month alcohol use completed a baseline survey as part of a larger randomized controlled trial.

Results

Results indicate that controlling for age, biological sex, race, ethnicity, and college enrollment, perceived descriptive norms and willingness to drink were associated with past 3-month concurrent alcohol and marijuana use and concurrent alcohol and prescription stimulant misuse. However, alcohol prototype similarity and alcohol-related perceived vulnerability were not associated with either concurrent use outcome examined.

Discussion

These findings suggest that alcohol-related perceived descriptive norms and willingness to drink are associated with concurrent substance use among young adults. Thus, it is possible that existing efficacious alcohol interventions that target descriptive norms and willingness to drink may have the added benefit of also reducing concurrent substance cognitions and ultimately use.

与酒精相关的认知：对年轻人同时使用酒精和大麻以及同时使用酒精和处方兴奋剂的影响

介绍

本研究检查了原型意愿模型的社会反应路径中与酒精相关的认知与同时（在指定时间段内使用两种或多种物质）使用 1）酒精和大麻以及 2）酒精和处方兴奋剂滥用之间的关联.

方法

作为一项更大的随机对照试验的一部分，美国 1,062 名报告过去 3 个月饮酒的新兴成年人（18-20 岁；54.5% 女性）的便利样本完成了基线调查。

结果

结果表明，控制年龄、生理性别、种族、民族和大学入学率、感知的描述性规范和饮酒意愿与过去 3 个月同时使用酒精和大麻以及同时滥用酒精和处方兴奋剂有关。然而，酒精原型相似性和与酒精相关的感知脆弱性与所检查的任一并发使用结果无关。

讨论

这些研究结果表明，与酒精相关的感知描述规范和饮酒意愿与年轻人同时使用物质有关。因此，现有的针对描述性规范和饮酒意愿的有效酒精干预措施可能具有减少并发物质认知和最终使用的额外好处。
