The novel coronavirus has not only brought along disruptions to daily socio-economic activities, but sickness and deaths due to its high contagion. With no widely acceptable pharmaceutical cure, the best form of prevention may be precautionary measures which will guide against infections and curb the spread of the disease. This study explored the relationship between COVID-19 knowledge, risk perception, and precautionary behavior among Nigerians. The study also sought to determine whether this relationship differed for men and women. A web-based cross-sectional design approach was used to recruit 1,554 participants (mean age = 27.43, SD = 9.75; 42.7% females) from all geopolitical zones in Nigeria, through social media platforms using a snowball sampling technique. Participants responded to web-based survey forms comprising demographic questions and adapted versions of the Ebola knowledge scale, SARS risk perception scale, and precautionary behavior scale. Moderated mediation analysis of the data showed that risk perception mediated the association between COVID-19 knowledge and precautionary behavior and this indirect effect was in turn moderated by gender. Results indicate that having adequate knowledge of COVID-19 was linked to higher involvement in precautionary behavior through risk perception for females but not for males. It was also noted that awareness campaigns and psychological intervention strategies on COVID-19 related activities may be particularly important for males more than females. Drawing from the health belief model, we recommend that COVID-19 awareness campaigns should target raising more awareness of the risks associated with the infection to make individuals engage more in precautionary behaviors.

In response to the global call for strategic information to understand the novel coronavirus, the dataset presented in this paper is an examination of COVID-19-related knowledge, risk perceptions and precautionary health behavior among Nigerians. The data were generated during the COVID-19 lockdown in the country through a survey distributed via an online questionnaire, assessing socio-demographic information (7 items), knowledge (5 items), information sources (1 item), risk perception (9 items), expected end of lockdown (1 item), and COVID-19 precautionary health behavior (10 items), from 28th March to 4th April, 2020, gathering a total of 1,357 responses. A combination of purposive and snowball techniques helped to select the respondents via Whatsapp and Facebook from 180 cities/towns in the 6 geopolitical zones of Nigeria. The survey data were analyzed using descriptive statistics. The entire dataset is stored in a Microsoft Excel Worksheet (xls) and the questionnaire is attached as a supplementary file. The data will assist in curbing the Coronavirus pandemic by offering evidence for strategic and targeted interventions as well as health policy formulations and implementation.

This study assessed knowledge and perceptions about COVID-19 among the general public in Nigeria during the initial week of the pandemic lockdown in the country. From March 28 to April 4, 2020, this cross-sectional survey used an anonymous online questionnaire to collect data from respondents within Nigeria. Purposive and snowball sampling techniques were used to recruit 1357 respondents, aged 15-70 years, from 180 cities and towns within Nigeria. Study data were analysed using descriptive statistics. Approximately more than half (57.02%) of the respondents were male with high level of education (48.86% bachelor’s degree or higher). Approximately half of the respondents (46.94%) opined that COVID-19 was “a biological weapon designed by the Chinese government.” About 94% of the respondents identified “contact with airborne droplets via breathing, sneezing, or coughing” as the most common mode of transmission; most respondents associated COVID-19 with coughing (81.13%), shortness of breath (73.47%) and fever (62.79%). “Regular hand washing and social distancing” was selected by most respondents (94.25%) as a way of preventing infection whereas 11.86% reported “consuming gins, garlic, ginger, herbal mixtures and African foods/soups” as preventive measures against COVID-19. Majority of the respondents (91.73%) thought COVID-19 is deadly; and most respondents (84.3%) got 4 or more answers correctly. It was also observed that the traditional media (TV/Radio) are the most common source of health information about COVID-19 (93.5%). Findings revealed that Nigerians have relatively high knowledge, mostly derived from traditional media, about COVID-19. Their perceptions of COVID-19 bear implications across public health initiatives, compliance with precautionary behavior as well as bilateral relations with foreign nations. Evidence-based campaign should be intensified to remove misconceptions and promote precautionary measures.

: Since COVID-19 currently has no proven cure but high morbidity and mortality, many people are living in fear of the virus along with other mental health challenges induced by the lockdowns and social distancing. Hence, this study aims to provide evidence on the co-occurrence and inter-relations between the fear of COVID-19, post-traumatic stress symptoms, and psychological distress in adherence to preventive health behavior among Nigerians. It also seeks to determine whether this process differs for men and women. The sample comprised 1,172 consenting young adults (mean age = 22.9 ± 6.6 years, 54.5% females) selected using a snowball sampling technique. Structural equation modeling (SEM) was used to test the mediation model of post-traumatic stress symptoms and psychological distress as parallel and serial mediators of the relationship between the fear of COVID-19 and preventive health behavior. The indirect effect of the fear of COVID-19 on preventive health behavior across gender was tested using moderation analysis. Results showed that post-traumatic stress symptoms and psychological distress serially and fully, in causal order, mediated the association between the fear of COVID-19 and preventive health behavior, and gender moderated the mediation effects. The research provides evidence that the fear of COVID-19 could trigger preventive health behavior through post-traumatic stress symptoms but reduces it through psychological distress, whereas the fear of COVID-19 has a slightly more positive impact on preventive health behavior among men.
