ABSTRACT
Objective To translate the English version of fear of coronavirus disease 2019 (COVID-19) scale (FCV-19S) into Chinese and assess its reliability and validity. Methods FCV-19S was translated and culture-adapted to form a Chinese version of fear of COVID-19 scale (FCV-19S-C). A total of 334 questionnaires were sent out online, including FCV-19S-C, Chinese version of depression, anxiety and stress scale (DASS-C21), impact of event scale-revised (IES-R) and public stigma scale. The reliability and validity of FCV-19S-C and the influencing factors of COVID-19 fear were analyzed with the survey data. Results FCV-19S-C contained 7 items. One common factor was extracted by exploratory factor analysis, reflecting that all items in the scale belonged to the common factor, which could explain 69.5% of total variation. The load of item factors ranged from 0.780 to 0.873, showing good construct validity. The total score of FCV-19S-C was positively correlated with the total scores of DASS-C21 and IES-R (r＝0.403 and 0.471, both P＜0.01), indicating that the scale had good concurrent validity. The Cronbach’s α coefficient of FCV-19S-C was 0.924, showing good reliability. Linear regression analysis showed that the influences of COVID-19 on the psychological level and family income could predict the total score of FCV-19S-C (β＝0.62 and 0.20, both P＜0.01). The total score of FCV-19S-C could predict the total score of the public stigma scale (β＝0.37, P＜0.01). Conclusion FCV-19S-C has good reliability and validity, and can be used as a tool to understand the public fear of COVID-19 in China. The fear of COVID-19 is related to the loss of family income and the public stigma of COVID-19 patients.
ABSTRACT
The central air conditioning ventilation system plays an important role in the air circulation of buildings such as centralized isolation medical observation points and general public buildings. In order to meet the requirements of COVID-19 epidemic prevention and control, Beijing Preventive Medicine Association organized Beijing CDC and other professional institutes to write up the group standard entitled "Technical specification for health risk investigation of central air conditioning ventilation system during the COVID-19 epidemic (T/BPMA 0006-2020)" . According to the particularity of central air conditioning ventilation system risk control during the outbreak of similar respiratory infectious diseases, based on current laws and regulations and the principle of scientific, practical, consistency and normative, 8 key points of risk investigations were summarized, which were the location of fresh air outlet, air conditioning mode, air return mode, air system, air distribution, fresh air volume, exhaust and air conditioner components. The contents, process, method, data analysis and conclusion of the investigation implementation were also defined and unified. It could standardize and guide institutions such as disease control and health supervision to carry out relevant risk managements, and provided solutions and technical supports for such major public health emergencies in city operations.
