We conducted a longitidinal assessment of 806 respondents in March, 2020 in the US to examine the trustworthiness of sources of information about COVID-19. Respondents were recontacted after four months. Information sources included mainstream media, state health departments, the CDC, the White House, and a well-known university. We also examined how demographics, political partisanship, and skepticism about COVID-19 were associated with the perceived trustworthiness of information sources and decreased trustworthiness over time. At baseline, the majority of respondants reported high trust in COVID-19 information from state health departments (75.6%), the CDC (80.9%), and a university (Johns Hopkins, 81.1%). Mainstream media was trusted by less than half the respondents (41.2%), and the White House was the least trusted source (30.9%). At the 4-month follow-up, a significant decrease in trustworthiness in all five sources of COVID-19 information was observed. The most pronounced reductions were from the CDC and the White House. In multivariate analyses, factors associated with rating the CDC, state health department, and a university as trustworthy sources of COVID-19 information were political party affiliation, level of education, and skepticism about COVID-19. The most consistent predictor of decreased trust was political party affiliation, with Democrats as compared to Republicans less likely to report decreased trust across all sources.
我们在 2020 年 3 月对美国的 806 名受访者进行了一项纵向评估，以研究他们对 COVID-19 相关信息来源的信任程度。四个月后对受访者进行了重新联系。信息来源包括主流媒体、州卫生部门、CDC、白宫和一所知名大学。我们还研究了人口统计学特征、政治党派立场以及对 COVID-19 的怀疑态度如何与信息来源的感知可信度以及随着时间的推移可信度的下降相关。在基线时，大多数受访者报告对州卫生部门（75.6%）、CDC（80.9%）和一所大学（约翰霍普金斯大学，81.1%）的 COVID-19 信息高度信任。不到一半的受访者信任主流媒体（41.2%），而白宫是最不受信任的来源（30.9%）。在 4 个月的随访中，观察到对所有五种 COVID-19 信息来源的信任度显著下降。CDC 和白宫的降幅最大。在多变量分析中，与将 CDC、州卫生部门和大学评为 COVID-19 信息可信来源相关的因素包括党派、教育程度和对 COVID-19 的怀疑态度。最一致的降低信任度的预测因素是党派，与共和党相比，民主党在所有来源中报告信任度下降的可能性更小。
