Knowledge, attitudes, and practices towards COVID-19 among the population of the state of São Paulo, Brazil.

BACKGROUND: The population's adherence to COVID-19 preventive measures is influenced by their knowledge, attitudes, and practices (KAP) towards the disease, making research into people's awareness of the disease essential. The present survey was designed to assess KAP towards COVID-19 among the population of the state of São Paulo, Brazil. METHODS: An online questionnaire was disseminated via social media between September 14 and October 5, 2020. The intended population was Brazilians over the age of 18, living in the state of São Paulo. RESULTS: A total of 1,111 individuals completed the questionnaire. The majority were women (71.6%), 31.6% were aged 31-40 years old, and 82.8% had higher education. Among the participants, 17.5% reported that they had taken some medication without a medical prescription to prevent COVID-19. The participants showed good knowledge about the transmission and prevention of the disease. The knowledge mean score was lower among participants with complete high school or less, with poor self-perception of their health status, who almost never seek information about COVID-19, and those who are not sure to belong to a risk group for the disease. Only 51.3% of the participants believed that COVID-19 would finally be successfully controlled, and 56.6% were confident that Brazil could win the battle against the virus. CONCLUSIONS: Participants demonstrated good knowledge of COVID-19 but were pessimistic about the pandemic's future. The findings of this study can help in the development of effective health communication strategies to promote better knowledge and a positive attitude about prevention measures.

Panorama of COVID-19, risk perception and vaccine confidence in São Paulo State population, Southeast Brazil.

In 2021, the COVID-19 pandemic remained uncontrolled in Brazil, with more than 17.6 million cases diagnosed and more than a half a million deaths in total. It is known that an accurate risk perception by populations and a consequent adherence to preventive measures can increase the effectiveness of policies to contain the transmission of infectious diseases. The objective of this study was to draw a panorama of COVID-19 in São Paulo State and investigate the population's risk perception about the new coronavirus, attitudes regarding preventive measures and vaccine confidence through an open web survey. A total of 1111 individuals participated (71.6% females). Of those, 15% declared themselves unemployed, almost 6% lost their jobs during the pandemic, and more than 30% suffered a decrease in their monthly income. As for the COVID-19, almost 32% of the participants were tested sometime in 2020, and 11.3% reported a confirmed diagnosis for a level of hospitalisation of 5%. As for the risk perception, it was observed that situations with crowds of people were more frequently considered as of high risk and cause of greater concern with contamination of family members than with themselves. Almost 23% of the participants questioned whether they would take the vaccine when available and do not know if the COVID-19 vaccine will be safe for the population. Almost 70% disagreed with the statement that the actions of the country's health authorities are effective in combating COVID-19. Considering the Cramer's V coefficient, these variables were not associated with gender or educational level.

Brazilian Portuguese versions and cross-cultural adaptation of two instruments to assess knowledge, attitude, and practice regarding the COVID-19 pandemic in the Brazilian population.

INTRODUCTION: Studies based on knowledge, attitude, and practice (KAP) theory are conducted to identify ways to improve strategies aimed at preventing and combatting certain conditions or diseases, to understand the way how behavioral changes are assimilated by the populations, and to reorient interventions. In view of the coronavirus disease 2019 (COVID-19) pandemic, studies based on KAP theory have been useful to better understand certain behaviors, such as adherence to prevention measures and control of the spread of the virus. OBJECTIVE: To describe the process of cross-cultural adaptation of two complementary instruments for assessing KAP regarding the COVID-19 pandemic in the Brazilian population. METHODS: Two independent translators proposed a first Brazilian Portuguese version of the scales. The cultural adaptation and pre-test of the Brazilian Portuguese versions occurred at different stages, using a panel of specialists and a subsample of the target population, respectively. RESULTS: The pre-test of the adapted instruments involved 30 Brazilian adults (mean age = 41.8 years; standard deviation = 4.24) and was carried out to assess instrument understanding and applicability. The participants informed they did not have difficulties to self-complete the instruments and reported a high level of clarity and understanding. CONCLUSION: Both instruments can bring an opportunity to study behavioral constructs about COVID-19 in the Brazilian population, aiming to articulate strategies that enable the fulfillment of effective preventive measures.
