Psychometric Methods for Developing and Evaluating Rating Scales: Why I Do What I Do
sponsored by ??

Speakers:
Sandringham Suite
Although classical test theory, generalizability theory and modern psychometrics (including Rasch analysis and IRT) are commonly
discussed in ISOQOL meetings and publications in our journal, Quality of Life Research, the appropriate use of these
different methods has not been discussed in a major forum within ISOQOL. To allow members to learn about the strengths and
appropriate use of each of these models for psychometric analysis, session chairs Jeremy Hobart and Stefan Cano will lead what
promises to be a lively session with some of the world’s experts in each of these methods answering the question “Why I Do
What I Do”.

Rating scales play a critical role in shaping health care and health outcomes. Several psychometric methods are used to develop
and validate health rating scales. Each has its strengths and no method is fully adequate to address all the requirements of
rigorous psychometric validation. Session chairs Jeremy Hobart and Stefan Cano invite experts in each of these methods to
present and discuss “Why I Do What I Do”. Invited speakers include leaders in the application of the following methods to patient
reported outcome data:
• Generalizability Theory
• Item Response Theory
• Rasch Measurement
