Measures of Interobserver Agreement and Reliability

Measures of Interobserver Agreement and Reliability, Second Edition covers important issues related to the design and analysis of reliability and agreement studies. It examines factors affecting the degree of measurement errors in reliability generalization studies and characteristics influencing the process of diagnosing each subject in a reliability study. The book also illustrates the importance of blinding and random selection of subjects.

New to the Second Edition

• New chapter that describes various models for methods comparison studies
• New chapter on the analysis of reproducibility using the within-subjects coefficient of variation
• Emphasis on the definition of the subjects’ and raters’ population as well as sample size determination

This edition continues to offer guidance on how to run sound reliability and agreement studies in clinical settings and other types of investigations. The author explores two ways of producing one pooled estimate of agreement from several centers: a fixed-effect approach and a random sample of centers using a simple meta-analytic approach. The text includes end-of-chapter exercises as well as downloadable resources of data sets and SAS code.
