Messages promoting the benefits of amber necklaces for children are common on social media, despite their health risks.
This study characterized Facebook posts with false content about the efficacy of amber necklaces in teething.
A sample of 500 English-language Facebook posts was analyzed by two investigators to determine the motivations, author's profile, and sentiments of posts. Latent Dirichlet Allocation topic modeling was used to identify salient terms and topics. An intertopic distance map was created to calculate the topic similarity. These data were analyzed using descriptive analysis, the Mann-Whitney U test, Cramer's V test, and multiple logistic regression models, regarding the time since initial posting and interaction metrics.
Most posts were made by business profiles and expressed positive sentiments, with social, psychological, and financial motivations. The posts were categorized into the topics "giveaway," "healing features," and "sales." Overperforming scores and total interaction increased with time since the initial posting. Posts with links had higher overperforming scores.
The findings suggest that Facebook posts about the efficacy of amber necklaces in teething are motivated by financial interests, using psychological and social mechanisms to achieve greater interaction with their target audience.
尽管琥珀项链对儿童存在健康风险，但在社交媒体上宣扬其益处的信息却很常见。
本研究对脸书上关于琥珀项链缓解出牙疼痛功效的虚假内容帖子进行了特征分析。
两名研究人员对500条英文脸书帖子样本进行了分析，以确定帖子的动机、作者简介和情感倾向。使用潜在狄利克雷分配主题模型来识别显著术语和主题。创建了一个主题间距离图来计算主题相似度。使用描述性分析、曼-惠特尼U检验、克莱默V检验和多元逻辑回归模型对这些数据进行了分析，涉及自首次发布以来的时间和互动指标。
大多数帖子由商业简介发布，表达了积极的情感，具有社会、心理和经济动机。这些帖子被归类为“赠品”“治疗功效”和“销售”等主题。自首次发布以来，超表现得分和总互动量随时间增加。带有链接的帖子超表现得分更高。
研究结果表明，脸书上关于琥珀项链缓解出牙疼痛功效的帖子是受经济利益驱动的，利用心理和社会机制来实现与目标受众的更多互动。
