Even though multiple states have approved legal recreational use of cannabis, the expansion of recreational cannabis legalization has led to public health concerns in the United States. Young adults (18-25 years old) have the highest percentage of cannabis use disorder compared to all other age groups. The purpose of this study is to compare cognitive and emotional responses of young adults who use cannabis and non-users to two anti-cannabis media campaigns that employed different message strategies. In total, 50 people (25 people who use cannabis and 25 non-users) participated in the study-a 2 (cannabis use status: people who currently use cannabis/non-users) × 2 (Public Service Advertising [PSA] campaign: Don't be a Lab Rat-Informational/Stoner Sloth-Narrative) × 3 (message replication) experiment. Participants viewed six messages based on the combinations of each of the three message replications within two campaigns. Participants' facial emotional responses were recorded during message exposure. Self-report questions were asked after viewing each message. Self-report indices showed no differences between the two campaigns for participants who use cannabis and non-users. However, after controlling for individual differences, participants who use cannabis displayed more negative emotional responses to the Don't be a Lab Rat messages than to the Stoner Sloth messages. Conversely, cannabis users experienced more positive emotional responses to the Stoner Sloth messages than to the Don't be a Lab Rat messages. The study provides insights for message design in public health campaigns addressing cannabis use, suggesting that psychophysiological measures can be helpful in providing insights into responses not detected by traditional self-report measures.
尽管多个州已批准大麻用于合法娱乐用途，但娱乐用大麻合法化的扩张在美国引发了公共卫生问题。与所有其他年龄组相比，年轻人（18至25岁）的大麻使用障碍比例最高。本研究的目的是比较使用大麻的年轻人和不使用大麻的年轻人对两项采用不同信息策略的反大麻媒体宣传活动的认知和情感反应。共有50人（25名使用大麻者和25名不使用者）参与了该研究——一项2（大麻使用状况：当前使用大麻者/不使用者）×2（公益广告[PSA]活动：别做实验鼠——信息型/懒鬼大麻虫——叙事型）×3（信息重复）实验。参与者根据两项活动中三种信息重复的每种组合观看了六条信息。在信息展示期间记录参与者的面部情绪反应。每条信息观看后都会询问自我报告问题。自我报告指标显示，使用大麻的参与者和不使用大麻的参与者在两项活动之间没有差异。然而，在控制个体差异后，使用大麻的参与者对“别做实验鼠”信息的负面情绪反应比对“懒鬼大麻虫”信息的更多。相反，大麻使用者对“懒鬼大麻虫”信息的积极情绪反应比对“别做实验鼠”信息的更多。该研究为解决大麻使用问题的公共卫生宣传活动中的信息设计提供了见解，表明心理生理测量有助于洞察传统自我报告测量未检测到的反应。
