Design and Psychometric Analysis of the COVID-19 Prevention, Recognition and Home-Management Self-Efficacy Scale.

People's self-efficacy to adopt preventive behaviours to avoid COVID-19 contagion and spread should be studied. The aim of this study was to develop and psychometrically test the COVID-19 prevention, detection, and home-management self-efficacy scale (COVID-19-SES). We conducted an observational cross-sectional study. Six-hundred and seventy-eight people participated in the study. Data were collected between March and May 2020. The COVID-19-SES' validity (content, criterion, and construct), reliability (internal consistency and test-retest reliability), and legibility were studied. The COVID-19-SES' reliability was high (Cronbach's alpha = 0.906; intraclass correlation coefficient = 0.754). The COVID-19-SES showed good content validity (scale's content validity index = 0.92) and good criterion validity when the participants' results on the COVID-19-SES were compared to their general self-efficacy (r = 0.38; p < 0.001). Construct validity analysis revealed that the COVID-19-SES' three-factor structure explained 52.12% of the variance found and it was congruent with the World Health Organisation's recommendations to prevent COVID-19 contagion and spread. Legibility analysis showed that the COVID-19-SES is easy to read and understand by laypeople. The COVID-19-SES is a psychometrically robust instrument that allows for a valid and reliable assessment of people's self-efficacy in preventing, detecting symptoms, and home-managing COVID-19.14 p.enCOVID-19PsychometricsSelf-efficacyInfecciones por coronavirusPsicometríaAutoeficaciaMedical Subject Headings::Psychiatry and Psychology::Behavioral Disciplines and Activities::Psychological Tests::PsychometricsMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Personality::Personality Development::Self Concept::Self EfficacyMedical Subject Headings::Persons::Persons::Age Groups::AdultMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cross-Sectional StudiesMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Persons::Persons::Age Groups::Adult::Middle AgedMedical Subject Headings::Health Care::Environment and Public Health::Public Health::Disease Outbreaks::Epidemics::PandemicsMedical Subject Headings::Diseases::Virus Diseases::Pneumonia, ViralMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Reproducibility of ResultsMedical Subject Headings::Geographical Locations::Geographic Locations::Europe::Spainresearch article32605250open access10.3390/ijerph171346531660-4601PMC7369931
