We characterized leading YouTube videos featuring alcohol brand references and examined video characteristics associated with each brand and video category.
We systematically captured the 137 most relevant and popular videos on YouTube portraying alcohol brands that are popular among underage youth. We used an iterative process to codebook development. We coded variables within domains of video type, character sociodemographics, production quality, and negative and positive associations with alcohol use. All variables were double coded, and Cohen's kappa was greater than .80 for all variables except age, which was eliminated.
There were 96,860,936 combined views for all videos. The most common video type was "traditional advertisements," which comprised 40% of videos. Of the videos, 20% were "guides" and 10% focused on chugging a bottle of distilled spirits. While 95% of videos featured males, 40% featured females. Alcohol intoxication was present in 19% of videos. Aggression, addiction, and injuries were uncommonly identified (2%, 3%, and 4%, respectively), but 47% of videos contained humor. Traditional advertisements represented the majority of videos related to Bud Light (83%) but only 18% of Grey Goose and 8% of Hennessy videos. Intoxication was most present in chugging demonstrations (77%), whereas addiction was only portrayed in music videos (22%). Videos containing humor ranged from 11% for music-related videos to 77% for traditional advertisements.
YouTube videos depicting the alcohol brands favored by underage youth are heavily viewed, and the majority are traditional or narrative advertisements. Understanding characteristics associated with different brands and video categories may aid in intervention development.
我们对YouTube上出现酒精品牌的热门视频进行了特征描述,并研究了与每个品牌及视频类别相关的视频特征。
我们系统地收集了YouTube上137个最相关且最受欢迎的视频,这些视频描绘了在未成年青少年中很受欢迎的酒精品牌。我们采用迭代过程来制定编码手册。我们对视频类型、角色社会人口统计学、制作质量以及与酒精使用的正负关联等领域的变量进行编码。所有变量都进行了双重编码,除年龄变量外(该变量被剔除),所有变量的科恩kappa系数均大于0.80。
所有视频的总观看量为96860936次。最常见的视频类型是“传统广告”,占视频总数的40%。其中,20%的视频是“指南”,10%的视频聚焦于大口喝一瓶蒸馏酒。虽然95%的视频以男性为主角,但有40%的视频中有女性。19%的视频中出现了酒精中毒的情节。出现攻击、成瘾和受伤情节的视频很少见(分别为2%、3%和4%),但47%的视频包含幽默元素。传统广告占百威淡啤相关视频的大部分(83%),但在灰雁和轩尼诗相关视频中分别只占18%和8%。大口喝示范视频中酒精中毒情节最为常见(77%),而成瘾情节仅在音乐视频中出现(22%)。包含幽默元素的视频在音乐相关视频中占11%,在传统广告中占77%。
YouTube上描绘未成年青少年喜爱的酒精品牌的视频观看量很大,且大多数是传统广告或叙事广告。了解与不同品牌和视频类别相关的特征可能有助于制定干预措施。
