Summer School in Applied Psychometrics From the website: Date: Monday, 12 September to Friday, 16 September Location: Peterhouse College, Cambridge Time: All Day Event "Health-related quality of life (HRQoL) is a popular and rapidly evolving area of psychometric research that builds on a long-standing methodology of self-report questionnaires. Today the assessment, analysis and interpretation of these questionnaires and of Patient-Reported Outcomes (PROs) rely upon a variety of modern psychometric methods that might be beyond the typical methodological/statistical training that researcher of related disciplines receive. This Summer School will cover the fundamentals of psychometric test theory as applied to HRQoL and PROs, with particular emphasis on latent trait/ Item Response Theory (IRT) models and methods, and will include practical sessions and data from real-world applications trials and cohort studies. The Summer School is supported by the ESRC RDI (Researcher D...

Cognitive interviewing in the evaluation of fatigue items: Results from the patient-reported outcomes measurement information system (PROMIS). Quality of Life Research. 2008 Oct 12. [Epub ahead of print] Department of Neurology, HSC T12-028, Stony Brook University, Stony Brook, NY, 11794-8121. OBJECTIVES: Cognitive Interviewing (CI) is a technique increasingly used to obtain respondent feedback on potential items during questionnaire development. No standard guidelines exist by which to incorporate CI feedback in deciding to retain, revise, or eliminate potential items. We used CI in developing fatigue items for the National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) Roadmap initiative. Our aims were to describe the CI process, formally evaluate the utility of decisions made on the basis of CI, and offer suggestions for future research. METHODS: Participants were ...
