HealthMeasures replied the topic: Should I use a PROMIS or a PROMIS-Ca Measure?
PROMIS and PROMIS-Ca measures produce slightly different scores. This difference was determined to be so small that comparing scores from a PROMIS measure and PROMIS-Ca measure is acceptable. Because the PROMIS measures have demonstrated validity across diverse patient populations, are linked with other PRO measures (i.e., PROsetta Stone at
), and have continued to be improved through item bank expansion (e.g., PROMIS Physical Function item bank v2.0), it is recommended to use the PROMIS measure with general population calibrations when assessing individuals with cancer.
