Understanding infectious diseases such as influenza is an important element of health literacy. We present a fully validated knowledge instrument called the Assessment of Knowledge of Influenza (AKI) and use it to evaluate knowledge of influenza, with a focus on misconceptions, in Midwestern United States high-school students. A two-phase validation process was used. In phase 1, an initial factor structure was calculated based on 205 students of grades 9–12 at a rural school. In phase 2, one- and two-dimensional factor structures were analyzed from the perspectives of classical test theory and the Rasch model using structural equation modeling and principal components analysis (PCA) on Rasch residuals, respectively. Rasch knowledge measures were calculated for 410 students from 6 school districts in the Midwest, and misconceptions were verified through the χ 2 test. Eight items measured knowledge of flu transmission, and seven measured knowledge of flu management. While alpha reliability measures for the subscales were acceptable, Rasch person reliability measures and PCA on residuals advocated for a single-factor scale. Four misconceptions were found, which have not been previously documented in high-school students. The AKI is the first validated influenza knowledge assessment, and can be used by schools and health agencies to provide a quantitative measure of impact of interventions aimed at increasing understanding of influenza. This study also adds significantly to the literature on misconceptions about influenza in high-school students, a necessary step toward strategic development of educational interventions for these students. 相似文献

1918—1919年大流感是一场世界性的灾难,它之所以迅速传播到世界各地,与第一次世界大战有密切关系。战时的人员集中和流动加速了疾病传播;战争造成的恶劣生活条件削弱了人们对疾病的抵抗力;战争环境下国家卫生防疫政策受到了极大干扰。这场流感造成了大量人口死亡,同时也加速了第一次世界大战的结束。 相似文献

The emergence of coronavirus disease 2019(COVID-19) not only poses a serious threat to the health of people worldwide but also affects the global economy. The outbreak of COVID-19 began in December 2019, at the same time as the influenza season. However, as the treatments and prognoses of COVID-19 and influenza are different, it is important to accurately differentiate these two different respiratory tract infections on the basis of their respective early-stage characteristics. We reviewed official documents and news released by the National Health Commission of the People's Republic of China, the Chinese Center for Disease Control and Prevention(China CDC), the United States CDC, and the World Health Organization(WHO), and we also searched the PubMed, Web of Science, Excerpta Medica database(Embase), China National Knowledge Infrastructure(CNKI), Wanfang, preprinted bioRxiv and medRxiv databases for documents and guidelines from earliest available date up until October 3 rd, 2020. We obtained the latest information about COVID-19 and influenza and summarized and compared their biological characteristics, epidemiology, clinical manifestations, pathological mechanisms, treatments, and prognostic factors. We show that although COVID-19 and influenza are different in many ways, there are numerous similarities;thus, in addition to using nucleic acid-based polymerase chain reaction(PCR) and antibody-based approaches, clinicians and epidemiologists should distinguish between the two using their respective characteristics in early stages. We should utilize experiences from other epidemics to provide additional guidance for the treatment and prevention of COVID-19. 相似文献

Using data collected from students at a fully networked university community, this study examines patterns of World Wide Web use and how they may relate to gratifications people seek from traditional media. Path analyses show that beliefs about the Web predict gratifications sought, and that the latter predict gratifications obtained, with considerable reliability. More importantly, entertainment, surveillance, and passing time—gratifications typically associated with television and newspaper use—prove to be significant predictors of World Wide Web site visitation. Thus, the data indicate that Internet use may be understood and predicted through the application of traditional gratification typologies. 相似文献
