Our October speaker is Dr. David Cella, who is on faculty at Northwestern University.
The measurement of health related quality of life (HRQL) has become an important and at times essential component of clinical trials and clinical effectiveness research. Historically, HRQL measures, or what have more recently become referred to as patient-reported outcomes, have been developed and validated using classical psychometric approaches that rely upon factor analysis and correlational methods. More recently, HRQL measures have been constructed to take advantage of a family of logistic regression methods typically referred to as item response theory (IRT). For over 30 years, IRT applications have dominated educational testing and played an important role in personality assessment. About 10 years ago, the health outcome measurement community took notice of some of the unique advantages offered by including IRT, item banking and its applications in the development and validation of health status assessment. This presentation will describe the introduction of IRT applications into HRQL assessment, illustrating improvements in precision and flexibility in assessment options. Emphasis will be placed on large NIH commitments to item banking and standardization of assessment, such as the Patient Reported Outcomes Measurement Information System (PROMIS), Neuro- QOL, and the emerging NIH Toolbox.
