Alcohol portrayal in movies and commercials is generally positive and might stimulate young people to drink. We tested experimentally whether portrayal of alcohol images in movies and commercials on television promotes actual drinking.
In a naturalistic setting (a bar lab), young adult male pairs watched a movie clip for 1 h with two commercial breaks and were allowed to drink non-alcohol and alcoholic beverages. These participants were randomly assigned to one of four conditions varying on the type of movie (many versus few alcohol portrayals) and commercials (alcohol commercials present or not).
Participants assigned to the conditions with substantial alcohol exposure in either movies or commercials consume more alcohol than other participants. Those in the condition with alcohol portrayal in movie and commercials drank on average 1.5 glasses more than those in the condition with no alcohol portrayal, within a period of 1 h.
This study-for the first time-shows a causal link between exposure to drinking models and alcohol commercials on acute alcohol consumption.
电影和商业广告中的酒精描绘通常是正面的,可能会刺激年轻人饮酒。我们通过实验测试了电影和电视商业广告中酒精形象的描绘是否会促进实际饮酒。
在自然环境(酒吧实验室)中,年轻成年男性成对观看了一个小时的电影片段,其间有两个商业广告插播,并允许他们饮用非酒精和酒精饮料。这些参与者被随机分配到四个条件中的一个,条件的差异在于电影中的酒精描绘数量(多还是少)和商业广告(是否有酒精广告)。
分配到电影或商业广告中大量酒精暴露条件下的参与者比其他参与者饮用更多的酒精。在 1 小时内,与没有酒精描绘的条件相比,那些在电影和商业广告中都有酒精描绘的条件下的参与者平均多喝了 1.5 杯酒。
这项研究首次表明,暴露于饮酒模型和酒精商业广告与急性酒精消费之间存在因果关系。
