社交媒体在COVID-19大流行期间传播信息和传播错误信息，影响了预防措施，包括社交距离和疫苗接受。在这项研究中，我们的目的是测试一系列社交媒体帖子的效果，这些帖子宣传COVID-19非药物干预措施（NPI）和疫苗意向，并比较3种常见信息来源的效果：政府机构，近同龄人父母和新闻媒体。从先前试验中招募的青少年女儿的母亲样本（N=303）于2021年1月至3月参加了一项3（信息源）× 4（评估期）的随机析因试验，以评估信息源在社交媒体活动中的影响，该活动涉及NPI（即社交距离），COVID-19疫苗接种，媒体素养以及关于COVID-19的母女沟通。周一至周五，母亲们每天在3个随机分配的Facebook私人群组中收到1条社交媒体帖子，每周涵盖所有4个主题，另外还有1条关于积极的非流行性主题的帖子，以促进参与。这三组帖子的信息相同，但不同之处在于帖子中的信息链接来自政府机构、近亲父母或新闻媒体。母亲报告了社交距离行为和自己和女儿的COVID-19疫苗接种意向，理论中介和协变量，基线和3周，6周和9周后随机化评估。与每个帖子相关的视图，反应和评论都被计算在内，以衡量对消息的参与度。几乎所有的母亲（n=298，98.3%）在整个9周的试验期内一直留在Facebook私人群组中，随访率很高（n=276，91.1%，完成3周后测; n=273，90.1%，完成6周后测; n=275，90.8%，完成9周后测;和n=244，80.5%，完成所有评估）。在意向治疗分析中，母亲的社交距离行为（B=-0.10，95% CI -0.12至-0.08，P<.001）和女儿（B=-0.10，95% CI -0.18至-0.03，P<.001）随时间推移而降低，但疫苗接种意向增加（母亲：B=0.34，95% CI 0.19-0.49，P<.001;女儿：B=0.17，95% CI 0.04-0.29，P=.01）。在近同伴来源组中，女儿社交距离的减少更大（B=-0.04，95% CI -0.07至0.00，P= 0.03），在政府机构组中较少（B=0.05，95% CI 0.02-0.09，P= 0.003）。被分配信息源的可信度越高，社会距离越大（母亲：B=0.29，95% CI 0.09-0.49，P<.01;女儿：B=0.31，95% CI 0.11-0.51，P<.01）和疫苗接种意向（母亲：B=4.18，95% CI 1.83-6.53，P<.001;女儿：B=3.36，95% CI 1.67-5.04，P<.001）。当母亲认为近同伴来源不可信时，母亲自我接种疫苗的意图可能增加（B=-0.50，95% CI -0.99 to-0.01，P =.05）。研究期间病例数的减少、政府限制的放松以及疫苗分发可能解释了社交距离的减少和疫苗接种意愿的增加。在宣传COVID-19预防时，活动策划者在选择受众认为可信的信息来源时可能会更有效，因为一般来说，没有任何来源更可信。ClinicalTrials.gov NCT02835807; https://clinicaltrials.gov/ct2/show/NCT02835807
Social media disseminated information and spread misinformation during the COVID-19 pandemic that affected prevention measures, including social distancing and vaccine acceptance. In this study, we aimed to test the effect of a series of social media posts promoting COVID-19 nonpharmaceutical interventions (NPIs) and vaccine intentions and compare effects among 3 common types of information sources: government agency, near-peer parents, and news media. A sample of mothers of teen daughters (N=303) recruited from a prior trial were enrolled in a 3 (information source) × 4 (assessment period) randomized factorial trial from January to March 2021 to evaluate the effects of information sources in a social media campaign addressing NPIs (ie, social distancing), COVID-19 vaccinations, media literacy, and mother–daughter communication about COVID-19. Mothers received 1 social media post per day in 3 randomly assigned Facebook private groups, Monday-Friday, covering all 4 topics each week, plus 1 additional post on a positive nonpandemic topic to promote engagement. Posts in the 3 groups had the same messages but differed by links to information from government agencies, near-peer parents, or news media in the post. Mothers reported on social distancing behavior and COVID-19 vaccine intentions for self and daughter, theoretic mediators, and covariates in baseline and 3-, 6-, and 9-week postrandomization assessments. Views, reactions, and comments related to each post were counted to measure engagement with the messages. Nearly all mothers (n=298, 98.3%) remained in the Facebook private groups throughout the 9-week trial period, and follow-up rates were high (n=276, 91.1%, completed the 3-week posttest; n=273, 90.1%, completed the 6-week posttest; n=275, 90.8%, completed the 9-week posttest; and n=244, 80.5%, completed all assessments). In intent-to-treat analyses, social distancing behavior by mothers (b=–0.10, 95% CI –0.12 to –0.08, P<.001) and daughters (b=–0.10, 95% CI –0.18 to –0.03, P<.001) decreased over time but vaccine intentions increased (mothers: b=0.34, 95% CI 0.19-0.49, P<.001; daughters: b=0.17, 95% CI 0.04-0.29, P=.01). Decrease in social distancing by daughters was greater in the near-peer source group (b=–0.04, 95% CI –0.07 to 0.00, P=.03) and lesser in the government agency group (b=0.05, 95% CI 0.02-0.09, P=.003). The higher perceived credibility of the assigned information source increased social distancing (mothers: b=0.29, 95% CI 0.09-0.49, P<.01; daughters: b=0.31, 95% CI 0.11-0.51, P<.01) and vaccine intentions (mothers: b=4.18, 95% CI 1.83-6.53, P<.001; daughters: b=3.36, 95% CI 1.67-5.04, P<.001). Mothers’ intentions to vaccinate self may have increased when they considered the near-peer source to be not credible (b=–0.50, 95% CI –0.99 to –0.01, P=.05). Decreasing case counts, relaxation of government restrictions, and vaccine distribution during the study may explain the decreased social distancing and increased vaccine intentions. When promoting COVID-19 prevention, campaign planners may be more effective when selecting information sources that audiences consider credible, as no source was more credible in general.
