Hypothesis
The study aims to create and validate the accuracy of the Post-COVID Cognitive Impairment Scale for evaluating cognitive impairments resulting from COVID-19.
Conclusion
The Post-COVID Cognitive Impairment Scale is a valid and reliable tool for assessing cognitive deficits in individuals with long COVID.
Supporting Evidence
- The scale demonstrated strong internal consistency with Cronbach’s Alpha values of 0.81 for working memory and 0.80 for attention.
- Exploratory factor analysis revealed two variables, memory and attention, accounting for 40.38% of the variation.
- Confirmatory factor analysis indicated satisfactory model fit with indices such as CMIN/DF = 2.80 and RMSEA = 0.06.
Takeaway
This study created a questionnaire to help doctors understand how COVID-19 affects people's thinking and memory, making it easier to help them feel better.
Methodology
The study involved developing the scale, evaluating its content validity with experts, and validating its structure with 454 participants using exploratory and confirmatory factor analysis.
Potential Biases
Self-reported data may introduce biases as participants could underreport or overreport symptoms based on their emotional state.
Limitations
The study's cross-sectional design limits the ability to assess changes in cognitive deficits over time, and the sample was drawn from a specific geographic region, which may affect generalizability.
Participant Demographics
Participants were aged 18 to 65, with 65.6% female and 34.4% male, and varied educational backgrounds.
