Effects of Health Information Dissemination on User Follows and Likes During the Novel Coronavirus Outbreak in China: Data Analysis (Preprint)

Abstract

BACKGROUND Since the novel coronavirus broke out in December 2019 in Wuhan, Hubei, it has completely spread in China. In this situation, articles were posted on many WeChat official accounts to transmit health information about this pandemic. The public also sought related information via social media more frequently. However, little is known about what kinds of information satisfy them better. OBJECTIVE This study aimed to explore the characteristics of health information dissemination that affected users’ behavior on WeChat. METHODS Two-wave data were collected from the top 200 WeChat official accounts on the Xigua website. The data, including the change in the number of followers and the total number of likes on each account in a 7-day period, were selected as dependent variables. The number of each type of articles and headlines about coronavirus served as independent variables. Multiple and simple linear regression models were used to conduct data analysis. In addition, the contents of the headlines with more than 10,000 likes were examined to further explore their characteristics. RESULTS The top 200 official accounts could be classified into three groups, namely, nonmedical institution, medical institution, and individual accounts. After filtering data, the sample size of these groups was 124. The multiple linear regression model of nonmedical and medical institution accounts had adjusted R2 of 0.355 and 0.452, respectively. For nonmedical institution accounts, the simple linear regression model had an adjusted R2 of 0.317. The other results were insignificant, and an ideal model for them could not be developed. However, R2 indicated an acceptable fit. For nonmedical institution accounts, report and story types of articles were significant, as indicated by the multiple linear regression model (B=2.724, P=.007; B=14.875, P=.003), and both types were identified to have positive effects on behavior. For the simple linear regression model, the number of headlines on coronavirus was observed to have a positive effect on behavior (B=3.084, P<.001). For medical institution accounts, reports and science types were significant, as revealed by the multiple linear regression model (B=4.381, P=.009; B=31.564, P<.001). They also had a positive effect. CONCLUSIONS Different characteristics in health information dissemination contribute to users’ behavior. For nonmedical institution accounts, report and story types positively influenced the change in the number of followers. For medical institution accounts, report and science types exerted positive effects. In headlines, organizational structure, manner of description, and multimedia applications contributed to unexpected likes. CLINICALTRIAL

Perception of “coronavirus” on the Polish Internet until arrival of SARS-CoV-2 in Poland

“…Wstępne doniesienia z Chin świadczą o dużym zaangażowaniu naukowców i władz w monitorowanie (i kontrolę) mediów społecznościowych w związku z epidemią SARS--CoV-2. [15][16][17] Poprzez analizę kluczowych momentów dyskursu medialnego wokół zjawiska rozprzestrzeniania się "koronawirusa" w Polsce zakłada się, że będzie można odtworzyć procesy kreowania zachowań poprzedzających ewentualną panikę wokół tematu epidemii i budowania świadomości epidemiologicznej polskiego społeczeństwa. Zaprezentowana w artykule analiza śladu cyfrowego może również stanowić egzemplifikację potrzeb informacyjnych społeczeństwa w obliczu zagrożenia nieznaną chorobą zakaźną, które niezaspokojone mogą doprowadzić do paniki.…”
