HTH RS M *727 / Theory and Practice of Measurement

3 unit(s)

Principles of subjective assessment in topic areas ranging from educational evaluation to patient-based measurement of health attitudes or health status. Discussion includes: principles and methods of constructing rating scales and approaches to assessing the measurement properties of such scales. Special emphasis on assessment of reliability and validity-various forms of reliability (test-re-test, interobserver, split-halves), distinction between reliability and agreement, and indirect methods to assess validity of an instrument in the absence of a “gold standard.” Advanced topics in generalizability theory will be introduced. Format is that of lecture, plus small group discussion.
