The Chi -square test was performed to compare differences in the prevalence of cyberbullying among groups with different sociodemographic characteristics, and the multivariate Logistic regression model was employed to analyze the risk factors. A risk predictive nomogram model was constructed and then verified.@*Results@#Middle school students were found to be victims of cyberbullying at a rate of 12.3%. The Logistic regression results showed that alcohol use ( OR =1.93), lack of emotional management ( OR =1.30), feeling unsafe ( OR =1.70), not trusting people ( OR =1.66), increased daily online time ( OR =1.39), higher frequency of using social software or websites ( OR =2.24), poor relationships with family members ( OR =1.46), parental neglect ( OR =1.50), class leadership ( OR =1.30) and poor relationships with classmates ( OR =1.34) were risk factors for middle school students who were victims of cyberbullying ( P <0.05). Based on these 10 independent risk factors, the nomogram prediction model, had good discrimination ( AUC =0.73).@*Conclusion@#Cyberbullying is common among middle school students. Internet use, parental neglect and class leadership all have an impact on cyberbullying.
ABSTRACT
OBJECTIVE@#To survey the residents for their understanding of Coronavirus Disease 2019 (COVID-19)-related knowledge, attitude and practices (KAP) in two hard hit provinces of China to facilitate the governmental decisions on strategies against the disease.@*METHODS@#We invited the participants from Hubei and Henan Provinces of China for an internetbased survey starting from 12:00 on February 21, 2020 to 12:00 on February 23. The survey included the general conditions, KAP of COVID-19, psychological status and living conditions of the residents.@*RESULTS@#The effective response rate of the questionnaire was 98.9%. The mean (P25, P75) age of the participants was 19 (16, 40) years, and 54.3% of them were students. Social media were the most important source of information concerning the pandemic of the respondents. The respondents had a high awareness of person-to-person transmission of the virus through the respiratory tract or droplets but showed a relatively low level of awareness of the population susceptible to COVID-19 and its specific symptoms. The results of multivariate analysis showed that women, undergraduate students (including college students) and higher degree holders had better knowledge of COVID-19 ( < 0.05); the proportion of respondents who expressed to have different levels of psychological stressed such as worry, anxiety and panic reached 77.2%; 16.7% of the responders considered psychological interventions necessary for their psychological conditions; 63.6% of the respondents confessed a bias against the people returning from Hubei and Henan provinces, while 22.4% worried that they might be biased because of their residence in Hubei and Henan. The rate of personal protective equipment shortage was as high as 69.4%; the rates of the responders who would "covering the mouth and nose when coughing or sneezing", "properly use masks in accordance with regulations", "maintain proper hand hygiene ", "avoid gatherings with relatives and friends" and "refrain from going to public places" were 92.4%, 95.9%, 93.5%, 88.8% and 93.1%, respectively. Women and groups with good knowledge of the disease reported better protective behaviors against the diseases ( < 0.05).@*CONCLUSIONS@#The residents in Hubei and Henan Provinces have generally good KAP related to COVID-19, and the online platforms plays a positive role to in circulating epidemic-related information. It is essential to further increase the supply of the protective materials and pay more attention to the mental health of the residents during the pandemic, and psychological counseling and psychological protection should be provided if necessary.
