Developing and validation of COVID-19 media literacy scale among students during the COVID-19 pandemic.

OBJECTIVE: This cross-sectional validation work evaluated the psychometric features of the COVID-19 Media Literacy Scale (C-19MLs) in Students. METHODS: The study was conducted on 530 students from a medical university in Hamadan, Iran, who were recruited through a stratified cluster random sampling process in June-July 2020. Intraclass Correlation Coefficient (ICC) and internal consistency were used to assess the reliability. Moreover, CFA (Confirmatory Factor Analyses) and EFA (Exploratory Factor Analyses) were carried out to examine construction validity. CVR (Content Validity Ratio) and CVI (Content Validity Index) were used to examine the content validity. RESULTS: According to the factor analysis, it was indicated that the C-19MLs included 21 items measuring five dimensions (constructedness of credible Covid-19 media messages, contractedness of fake media coronavirus messages, fake media coronavirus messages, audience, with three questions in each factor; format, represented lifestyles in fake media coronavirus messages with six questions in each factor) for an explanation of 58.4% of the prevalent variance. The average scores for the CVI and CVR were respectively 0.94 and 0.77. According to confirmatory factor analysis, the studied model had an appropriate fitting to the data; the relative chi-square (x2/df) = 2.706 < 3, RMSEA = 0.093 ≤ 0.1; CFI = 0.893 ≥ 0.9; TLI = 0.874 ≥ 0.9; GFI = 0.816 ≥ 0.9; and SRMR = 0.06 ≤ 0.08. Further analyses represented acceptable findings for internal consistency reliability values with 0.86 of Cronbach's alpha. CONCLUSIONS: The results proved that the C-19MLs is a reliable and valid tool, and it is suitable and acceptable now and can be utilized in forthcoming investigations. This highlights educators and stakeholders to realize the importance of participating individuals in the new media ecology and new 'Infomedia' ecosystems for enabling people in the current digital society.

Covid-19 Preventive Behaviors in Iranian People: Applying Health Belief Model.

Covid-19 disease, as a common infectious disease, has caused infection and death. Preventive behaviors are among the most important essential strategies of the Covid-19 disease prevention and control program. The health belief model (HBM) is one of the models that have been used to investigate the effective motivational factors and ultimately the protective behavior of the individual. Therefore, this study was conducted to define the factors related with Covid-19 protection behaviors among patients referred to comprehensive health service centers in Tuyserkan city using the HBM. A total of 800 patients referred to the comprehensive health service centers of Tuyserkan city during November 2021 were selected as the statistical population of this descriptive-analytical study. Clients were selected by multi-stage cluster random sampling from 21 comprehensive health service centers and health bases and then entered the study through simple random sampling. Data collection was online and based on a questionnaire. The questionnaire consisted of two parts: demographic information and HBM structure. The analysis was performed using SPSS24 software after data collection. The mean age of the subjects was 48.80 years and the income of the majority of the subjects was low (86.5%). People who washed their hands frequently kept a social distance, avoided losing others, used masks and gloves were 54.2%, 72.5%, 79.8%, 53.9%, 7.9% respectively. The results showed that with one unit increase in self-efficacy score and practice guide, the average behavior score increased by 0.27 and 0.31. The results show that the importance of prevention of Covid-19 infection among the population is necessary due to the high prevalence of infection and mortality. It seems that in intervention and prevention programs, the factors of prevention of Covid-19 transmission should be fully identified and proper interventions should be planned and implemented based on affective factors.

Household Secondary Attack Rate of COVID-19 among Healthcare Workers and Related Factors.

Background: The risk for transmission of COVID-19 to people in close contact with infected people, especially healthcare workers, has not been well estimated. Therefore the present study was conducted to assess the household secondary attack rate (SAR) of COVID-19 among healthcare workers and related factors. Materials and Methods: The present prospective case-ascertained study was conducted on 202 healthcare workers with confirmed COVID-19 in Hamadan, diagnosed from March 1, 2020, to August 20, 2020. For households with close contact with the index case, RT-PCR was performed regardless of symptoms. We defined SAR as the proportion of secondary cases from the total contacts that live in the index case household. SAR was reported as a percentage and 95% confidence interval (CI). Multiple logistic regression was performed to explore the predictors of COVID-19 transmission of index cases to their households. Results: We found 36 secondary cases out of 391 household contacts with laboratory confirmation (RT-PCR), representing a household SAR of 9.2% (95% CI: 6.3, 12.1). Among factors related to the family member, female gender (OR: 2.9, 95% CI: 1.2, 6.9), being the patient's spouse (OR: 2.2, 95% CI: 1.0, 4.6), and living in the apartment (OR: 2.78, 95% CI: 1.24, 6.23), and among factors related to index cases, hospitalization (OR: 5.9, 95% CI: 1.3, 26.9) and caught (OR: 2.4, 95% CI: 1.1, 5.2) were the significant predictors of disease transmission to other family members (P<0.05). Conclusion: The findings of this study suggest that the SAR is remarkable in household contacts of infected healthcare workers. Some characteristics of family members of the index case, including female gender, being the patient's spouse, and living in the apartment, and some characteristics of the index case, including hospitalization and caught, were associated with the increased SAR.

COVID-19 Prevention Behaviors among Health Staff: Data from a Large Survey in the West of Iran.

BACKGROUND: Hospital staffs are at high risk of Novel Coronavirus (2019-nCoV preventive behaviors play a peculiar role in the reduction of the incidence and mortality of this infection. Therefore, the present study aimed to assess the prevention behaviors of COVID-19 among health staff based on the Extended Parallel Model (EPPM) in western Iran. STUDY DESIGN: It was a cross-sectional study. . METHODS: The present study was performed in the west of Iran in April 2020. In total, 1,664 cases were enrolled in this study via multi-stage sampling. The data were collected using a questionnaire, including the demographic characteristics of participants and EPPM constructs. All analyses were conducted in Stata software (version 14) at a 5% significant level. RESULTS: As evidenced by the obtained results,  1,523 (91.53%), 1,226 (73.68%), 1,526 (91.71%), 893 (53.67%), and 862 (51.86%) of health staff wear gloves, use masks, avoid contact with others, maintain a good distance from other people, and wash their hands frequently with water and soap, respectively. In terms of using gloves and avoiding contacts with others, participants with high perceived threat had higher odds of observing health behaviors (OR= 3.14, 95% CI: 2.08, 4.73; P<0.001) and (OR= 3.1, 95% CI: 2.04, 4.69; P<0.001), respectively. In all categories of EPPM, the participants with high efficacy had higher odds of exhibiting health behaviors, compared to those with low efficacy (P<0.001). CONCLUSION: The results of the present study demonstrated that  health workers are expected to be at the highest level of threat and efficiency. Moreover, the findings emphasized the effectiveness of the recommended strategies in the prevention of COVID-19 disease.

Fear control and danger control amid COVID-19 dental crisis: Application of the Extended Parallel Process Model.

OBJECTIVES: There is high risk of contamination with COVID-19 virus during routine dental procedures and infection control is crucial. The aim of this study was to determine the factors associated with Covid-19 preventive behaviors among oral health care providers using an extended parallel process model (EPPM). METHODS: In a cross-sectional study, short text message invite surveys were sent to 870 oral health care providers in west part of Iran. Data were collected through validated self-report EPPM questionnaires. Descriptive statistics, Chi-square and Fishers exact tests were used for data analysis. RESULTS: In total, 300 completed questionnaires were received and the mean age of respondents was 29.89 ± 11.17 years (range: 20-75 years). Among the study population, 284 (94.67%) perceived the threat of infection highly. Washing hands frequently with water and soap and use of hand sanitizer was reported by 93.33%, of participants. Age (P = 0.010), sex (P = 0.002) and occupation field (P = 0.010) were significantly associated with danger control responses. Data identified that those oral health care providers that were on the danger control response adopted preventive behaviors more strictly than those on fear control response. CONCLUSION: The results of this study showed how degrees of perceived threat and perceived efficacy influenced oral health providers' willingness to perform recommended health behaviors. These findings can assist public health agencies in developing educational programs specifically designed for promoting preventive behaviors among oral health providers in pandemic situations.
