The goal of this pilot study was to assess the feasibility of a 9-day, smartphone-based ecological momentary assessment (EMA) protocol for tracking the frequency of Canadian adolescents' exposures to cannabis marketing, their reactions to such exposures, and the context in which exposures occur in the real-world and in real-time.
Participants were n = 18 adolescents between the ages of 14 and 18 years of age. They used an EMA application to capture and describe cannabis marketing exposures through photographs and brief questionnaires assessing marketing channel and context. Participants also rated their reactions to each exposure in real-time.
Results showed that participants were generally compliant with the protocol. Participants recorded 40 total exposures to cannabis marketing, representing an average of 2.2 ( 2.3) exposures per participant during the 9-day study. Exposures tended to occur in the afternoon (45.0%) or evening (37.5%), and while participants were at home (70%) and alone (52.5%). Most exposures occurred through promotion by public figures (27.5%) or explicitly marked internet ads (27.5%).
This is the first study to demonstrate the feasibility and utility of EMA to capture adolescent exposures to cannabis marketing as it occurs in participants' natural environments. Our research offers an early look at the predictable wave of cannabis advertising targeting youth and a promising approach for studying its impacts in a post-legalization context, as well as a strategy for assessing policies, such as advertising restrictions, intending to mitigate the harms of early cannabis use among youth.
本试点研究的目的是评估一项为期9天、基于智能手机的生态瞬时评估（EMA）方案的可行性，该方案用于追踪加拿大青少年接触大麻营销的频率、他们对这种接触的反应，以及在现实世界和实时环境中接触发生的背景。
参与者为18名年龄在14至18岁之间的青少年。他们使用EMA应用程序，通过照片以及评估营销渠道和背景的简短问卷来捕捉和描述大麻营销接触情况。参与者还实时对每次接触的反应进行评分。
结果显示参与者总体上遵守了该方案。在为期9天的研究中，参与者共记录了40次大麻营销接触，平均每名参与者接触2.2（±2.3）次。接触倾向于在下午（45.0%）或晚上（37.5%）发生，且参与者当时在家（70%）且独自一人（52.5%）。大多数接触是通过公众人物的宣传（27.5%）或明确标注的网络广告（27.5%）发生的。
这是第一项证明EMA在捕捉青少年在自然环境中接触大麻营销方面的可行性和实用性的研究。我们的研究初步观察了针对青少年的大麻广告的可预测浪潮，以及在大麻合法化背景下研究其影响的一种有前景的方法，同时也是评估旨在减轻青少年早期使用大麻危害的政策（如广告限制）的一种策略。
