A population-based nationwide dataset concerning the COVID-19 pandemic and serious psychological consequences in Bangladesh

This paper presents the dataset concerning knowledge, preventive behavior, psychological consequences, and suicidal behavior regarding the COVID-19 pandemic in Bangladesh. Data were collected through an online based cross-sectional survey between April 1 and April 10 in 64 districts at the early stage of the COVID-19 pandemic in Bangladesh. A total of 10,067 participants’ data were recruited for analysis. The survey contained items concerning (i) socio-demographic information, (ii) knowledge concerning COVID-19, (iii) behavior towards COVID-19, (iv) lockdown and economic issues, (v) assessment of fear of COVID-19, (vi) assessment of insomnia, (vii) assessment of depression, and (viii) assessment of suicidal ideation. Data were analyzed utilizing SPSS (version 22) and are represented as frequencies and percentages based on responses to the whole survey. Given that the data were collected across the whole nation, government authorities and healthcare policymakers can use the data to develop various models and/or policies regarding preventive strategies and help raise awareness through health education towards COVID-19.

Specifications
The target population were individuals in the 64 districts of Bangladesh. Socio-demographic information, COVID-19 knowledge-related questions, COVID-19 behavior-related questions, Bangla Fear of COVID-19 Scale, Bangla Insomnia Severity Index, Bangla Patient Health Questionnaire, and COVID-19-related suicidal behavior were assessed in the survey . Description of data collection Non-random convenience sampling using an online data collection platform was used to collect 10,067 participants' data from a convenience sample from all 64 districts in Bangladesh. The surveys were accessed and completed via social media platform (i.e., Facebook, WhatsApp, Twitter, Snapchat, etc.), email, and via other online communicable means. Data

Value of the data
• This dataset is useful because it comprises data from a largescale nationwide study concerning (i) socio-demographics, (ii) COVID-19-related knowledge, (iii) COVID-19-related behavior practices, (iv) lockdown and economic issues, (v) fear of COVID-19, (vi) depression, (vii) sleep patterns and insomnia, and (viii) suicidal ideation. • Government departments along with non-government organizations can use the dataset for facilitating public policy in relation to COVID-19. • Screening for suicide and depression can be applied in those regions which are badly affected during the COVOD-19 pandemic. • These data can be used to make comparisons with the mental health states of populations in other countries (including suicidal ideation).
• To reduce panic and related mental health consequences due to COVID-19, these data can be a major resource for helping developing evidence-based intervention and prevention programs. Further analysis of the dataset can be used to aid new methods and/or models to aid good mental health among Bangladeshi people during the COVID-19 pandemic.

Data Description
As the COVID-19 pandemic has spread out throughout the world, many Bangladeshi communities have been negatively impacted by COVID-19. In Bangladesh, during the early stage of COVID-19 pandemic, an online-based survey was conducted which collected data assessing the level of COVID-19 knowledge, attitudes, and practice among the Bangladeshi general population. The final dataset comprised a total of 10,067 participants. The dataset comprises (i) sociodemographic characteristics (e.g., gender, age group, educational status, occupational status, data discipline, residence area, marital status, comorbidities, current health condition, smoking status, alcohol-drinking status, frequency of social media use, etc.) ( Table 1 ); (ii) sources from where participants get information regarding COVID-19 (e.g., social media, YouTube , newspaper, television, health-related website, and other sources) ( Table 1 ); (iii); participants' knowledge concerning COVID-19 ( Table 2 ); (iv) participants' behavior in preventing COVID-19 ( Table 3 ); (v) lockdown-related questions ( Table 4 ); (vi) assessment of fear of COVID-19 among participants ( Table 5 ); (vii) assessment of severity of insomnia among participants ( Table 6 ); (viii) assessment of depression among participants ( Table 7 ); and (ix) suicidal ideation in relation to COVID-19 among participants ( Table 7 ). Detailed information concerning all of the variables are shown in Tables 1 -8 . A copy of the complete survey can be accessed as a Supplementary File.

Experimental Design, Materials and Methods
Cross-sectional data collection was carried out among 64 districts of Bangladesh between April 1 and 10 (2020). In each district, three or four research assistants (approximately 250 in total) were utilized to facilitate the completion of an online survey form via social media platforms among individuals living in those districts (approximately 250 RAs). A total of 10,067 participants out of approximately 11,0 0 0 were eligible. The inclusion criteria were (i) being Bangladeshi, (ii) residing in Bangladesh, and (iii) being aged over 10 years.
The survey comprised socio-demographic information including age, gender, educational status, occupational status, current place of residence, marital status, current cigarette smoking behavior (yes/no), current alcohol-drinking behavior (yes/no), and frequency of social media use. Current health status was assessed using a single question (i.e., "Are you suffering from any of the following health-related issues?") with seven response choices (i.e., diabetes, high blood pressure, asthma/respiratory problem, heart disease, kidney problems, cancer, and any other health conditions not listed) where each positive response was scored as one point.
COVID-19 knowledge was assessed based on questions relating to: (i) spread of infection (six true/false statements; e.g. 'COVID-19 can spread by touching others' ), (ii) symptoms (six true/false statements; e.g., 'The most common symptoms of COVID-19 are fever, tiredness, and dry cough' ), (iii) prevention behaviors (six true/false statements; e.g ., 'Washing hands regularly for 20 s') , and (iv) treatment (two statements; e.g., 'Taking pills like antibiotics when you have fever' ). To create a total COVID-19 knowledge score, each correct answer scored one point and incorrect answers scored zero. All responses are summed to calculate a total score ranging from 0 to 20 where higher scores reflected better knowledge concerning COVID-19. There is no recoding of any items in calculating the total score [1] .
COVID-19 preventive behavior was assessed based on four items (e.g., "How often do you clean your hands with an alcohol-based hand rub or wash them with soap and water?") responded to on   Insomnia was assessed using the Bangla Insomnia Severity Index which comprises seven item (e.g., "How satisfied/dissatisfied are you with your current sleep pattern?") responded to on a five-point Likert scale from 0 ( very satisfied ) to 4 ( very dissatisfied ). All items are summed up to calculate a total score ranging from 0 to 28, with higher scores indicating higher insomnia symptomology. There is no recoding of any items in calculating the total score [3] .
Depression was assessed using the Bangla Patient Health Questionnaire which comprises nine items (e.g., "Little or interest or pleasure in doing things") responded to on a five-point Likert scale from 0 (not at all) to 3 (nearly every day). All items are summed to calculate a total score ranging from 0 to 27, with higher scores indicating higher levels of depression. There is no recoding of any items in calculating the total score [ 4 , 5 ]. COVID-19-related suicidal behavior was assessed using a binary (yes/no) response to a single question ( "Do you think about committing suicide, and are these thoughts persistent and related to COVID-19 issues?") which was used in previous Bangladeshi studies [ 5 , 6 ]. Data were analyzed using the Statistical Packages for Social Science (SPSS) version 23.0, AMOS version 23.0 and ArcGIS 10.5 for analysis. Frequency and percentages were calculated.
