Insights
A new scale effectively measures healthcare provider adherence to COVID-19 hospital safety practices. This validated tool ensures reliable assessment of good practices, crucial for preventing virus transmission in healthcare settings.
Area of Science:
- Healthcare Management
- Infectious Disease Control
- Psychometrics
Background:
- Hospital transmission of COVID-19 necessitates strict adherence to prevention measures.
- Assessing healthcare provider adherence to good practices is vital for effective infection control.
- A validated instrument is needed to reliably measure adherence to COVID-19 precautions in hospitals.
Purpose of the Study:
- To evaluate the psychometric properties of a novel scale designed to assess adherence to good COVID-19 practices in a hospital setting.
- To determine the reliability and validity of the Adherence to Standard Precautions for COVID-19 scale.
- To confirm the factorial structure and internal consistency of the newly developed scale.
Main Methods:
- A cross-sectional study involving 307 healthcare providers in a Brazilian public hospital.
- Data collection included sociodemographic information and the Adherence to Standard Precautions for COVID-19 scale.
- Psychometric evaluation employed Cronbach's alpha, intraclass correlation coefficients, Spearman's correlation, exploratory, and confirmatory factor analysis.
Main Results:
- The scale demonstrated high internal consistency (Cronbach's alpha > 0.7 for most domains) and temporal stability (ICC > 0.7).
- Strong concurrent validity was observed between the total scale score and its personal (0.84) and organizational (0.90) domains.
- Confirmatory factor analysis supported a satisfactory fit for the three-dimensional structure of the scale.
Conclusions:
- The novel Adherence to Standard Precautions for COVID-19 scale is a valid and reliable instrument.
- This scale can be effectively used to assess adherence to good hospital practices for COVID-19 prevention.
- The findings support the use of this scale to improve infection control measures in healthcare settings.
Abstract:
To avoid hospital transmission, all COVID-19 prevention measures should be followed. This study aimed to evaluate the psychometric properties of a novel scale developed to assess adherence to good practices for COVID-19 in the hospital setting. A methodological cross-sectional study was conducted at a public hospital in the state of São Paulo, Brazil, with 307 healthcare providers. Data were collected using a questionnaire addressing sociodemographic/occupational data and the Adherence to Standard Precautions for COVID-19 scale. Cronbach's alpha coefficients and the intraclass correlation coefficients were used to measure internal consistency and temporal stability (test-retest analysis), respectively. Concurrent validity was evaluated using Spearman's correlation coefficients between the scores of the overall scale and its domains. Factorial structure was evaluated using exploratory factor analysis and goodness-of-fit of the model was tested using confirmatory factor analysis. Cronbach's alpha coefficients for the scale and its domains were higher than 0.7, except the psychosocial domain (0.61). All intraclass correlation coefficients were higher than 0.7. Strong correlations were found between the total score and the personal (0.84) and organizational (0.90) domains of the scale and a good correlation was found with the psychosocial domain (0.66). The fit of the multidimensional model was satisfactory for all parameters and the three-dimensional structure of the scale was confirmed by the fit of the factor loadings. The novel scale is a valid and reliable instrument for assessing adherence to good hospital practices for COVID-19.
