Brief summary

This study aims at investigating handwashing behavior during COVID-19 pandemic. It was hypothesized that social-cognitive and emotional predictors as well as COVID-19 morbidity and mortality rates within the country would be associated with handwashing behavior in the general population of adults in 14 countries.

Detailed description

This observational study aims at testing the adherence to handwashing guidelines (the World Health Organization, WHO, 2020) at two measurement points, spanning 1 month. Adults from the general population in 14 countries (Poland, Australia, Canada, China, France, Gambia, Germany, Israel, Italy, Malaysia, Portugal, Romania, Singapore, Switzerland) will provide self-report data on handwashing behavior and its social-cognitive predictors (perceived effectiveness of handwashing, risk perception, outcome expectancy, self-efficacy, intention, planning, and action control), anxiety, as well as COVID-19 morbidity and mortality rates within the country.

Design outcomes

Primary

MeasureTime frameDescription
Handwashing adherence1 monthThe 12-item self-report measure of adherence to handwashing guidelines across situations (e.g., after visiting public spaces, after touching garbage, etc.) based on the guidelines issued by the World Health Organization and the Centers for Disease Control and Prevention. The responses are provided on a 4-point scale, ranging from 1 (strongly disagree) to 4 (strongly agree). Higher scores indicate better outcomes (the higher level of adherence to handwashing guidelines).
Frequency of handwashing1 monthThe 1-item self-report measure of the frequency of handwashing (for at least 20 seconds, all surfaces of the hands) daily. The responses are provided on a 4-point scale, ranging from 1 (less than once) to 5 (more than 10 times). Higher scores indicate better outcomes (the higher frequency of handwashing).

Secondary

MeasureTime frameDescription
Outcome expectancy1 month4 items assessing positive (1 item) and negative (1 items) outcome expectancies; mean item scores ranging from 1 to 4, higher scores indicate more positive outcome expectancies
Intention1 month2 questionnaire items assessing intention to adhere to handwashing recommendations; mean item scores ranging from 1 to 4, higher scores indicate stronger intention to wash hands (for at least 20 seconds, all surfaces of the hands)
Planning1 month2 questionnaire items assessing action planning (1 item) and coping planning (1 item); mean item scores ranging from 1 to 4, higher scores indicate a higher level of self-reported planning
Self-efficacy1 month4 self-efficacy questionnaire items; mean item score ranging from 1 to 4, higher scores indicate stronger self-efficacy
Perceived effectiveness of hand hygiene1 month1 questionnaire item assessing perceptions of handwashing as an effective means of preventing coronavirus SARS-CoV-2 infection; item scores ranging from 1 to 4, higher scores indicate a higher level of perceived effectiveness of hand hygiene
Anxiety1 month7-item self-report scale (Generalized Anxiety Disorder, GAD-7) scale to assess anxiety symptoms; mean item scores ranging from 1 to 4, higher scores indicate a higher level of generalized anxiety
Country-level COVID-19 morbidity and mortality rates60 daysThe daily cumulative numbers for COVID-19 morbidity and mortality in the study countries. Published daily as the Situation Report by World Health Organization, starting on 21 January 2020. Higher numbers indicate the higher cumulative COVID-19 morbidity and mortality rates in the country.
Action control1 month3 questionnaire items assessing a facet of action control, namely self-monitoring; mean item scores ranging from 1 to 4, higher scores indicate a higher level of self-reported monitoring of handwashing behavior
Risk perception1 month3 questionnaire items to assess risk perception; mean item score ranging from 1 to 5, higher scores indicate higher risk perception
