10 Questions
What is the primary purpose of using the Intraclass Correlation Coefficient (ICC)?
To standardize estimates of measurement reliability without units
Which of the following is the recommended interpretation for an ICC value greater than 0.75?
Good reliability
What is the key difference between the ICC and the Standard Error of Measurement (SEM)?
The ICC provides standardized estimates of reliability, while the SEM provides unstandardized estimates
Which of the following is the recommended interpretation for an ICC value less than 0.75?
Poor to moderate reliability
What is the primary factor to consider when interpreting the magnitude of an ICC value?
The magnitude of the clinical decision being made
Which of the following is the recommended interpretation for an ICC value greater than 0.9?
Best for clinical measurements
What is the relationship between the ICC and the minimum detectable change (MDC) of a measurement?
There is no direct relationship between the ICC and MDC
Which statistic is typically reported in conjunction with the ICC to provide additional information about measurement reliability?
The standard error of measurement (SEM)
Which of the following statements about the use of the ICC with ordinal data is correct?
The ICC can be used with ordinal data if the intervals are assumed to be equivalent
What is the primary purpose of calculating the minimum clinically important difference (MCID) for a measurement?
To determine the minimum change in a measurement that is considered clinically meaningful
This quiz covers the concept of Minimum Clinically Important Difference (MCID) in healthcare, including its importance, interpretation, and application in patient care. Learn about how MCID helps measure the smallest beneficial change in an outcome measure perceived by patients.
