Shayna Egan, Mary Lynn Cala, Alp Tutuncu, Aisling Ryan, Brooke Witherspoon, Daniel Serrano and Chris Evans will be presenting several posters at the 22nd Annual ISPOR meeting in Boston in May. For this ISPOR we decided to skip the traditional posters, presentations and workshops on instrument development and validation work and present some methodological work we have been conducting which we hope will advance the field some. The topics included:
- Proximal versus distal impacts of disease: drivers of bothersomeness ratings in patient-reported outcomes studies.
- What is being measured in patient-reported outcome measures? Symptom questions may often reveal impact answers.
- Are patients’ responses to five point verbal descriptor scales and visual analogue scales replicate measures? An experimental manipulation.
- Pain assessment: a myriad of techniques to measure pain severity – does it matter which one is used?
