16 Questions
Which measure assesses the agreement between two raters beyond chance?
Cohen's Kappa (k)
Which measure assesses the reliability of measurements made by multiple observers on a continuous scale?
Intra-Class Correlation (ICC)
Which measure is used when assessing agreement on categorical data, such as diagnoses or classifications?
Cohen's Kappa (k)
Which measure is used to assess the consistency and reliability of data in health sciences research?
Lin's Concordance Correlation Coefficient
Which measure would be most suitable for evaluating the level of agreement beyond what would be expected by chance in a study comparing diagnoses of two psychiatrists regarding the presence or absence of a specific mental health disorder in patients?
Test-Retest Reliability
What is the formula for the Youden's J statistic?
Youden's J = Sensitivity + Specificity - 1
What does Krippendorff’s Alpha measure?
Agreement that accommodates various types of scales
What is the interpretation of Lin's Concordance Correlation Coefficient values?
-1 to 1, with 1 indicating perfect agreement
When is Percentage Agreement commonly used?
For binary outcomes
What does the ICC assess?
Reliability of measurements taken by different raters
What is the interpretation of Youden's J ranging from -1 to 1?
'Perfect test performance (perfect sensitivity and specificity)'
What type of data is Krippendorff’s Alpha commonly applied to?
Qualitative data in content analysis or coding in qualitative research.
In what context is Lin's Concordance Correlation Coefficient useful?
Assessing how closely measurements agree and how far they deviate from a perfect correlation.
What does Percentage Agreement calculate?
The percentage of agreement between raters.
What does the ICC formula MSB+(k-l)MSW assess?
Between-group variability relative to within-group variability.
What does Youden's J statistic indicate when it ranges from 0 to 1?
Better diagnostic test performance.
