You can also find information about about PROMIS-Ca in the PROMIS Scoring Manuals such as PROMIS Fatigue. You can find PROMIS Scoring Manuals here: www.healthmeasures.net/index.php?option=...le&id=180&Itemid=994
PROMIS-Cancer (PROMIS-Ca) measures (Physical Function, Fatigue, Pain Interference, Depression and Anger) were developed under the PROMIS Cancer Supplement (CaPS) grant from NCI. The measures are highly similar to PROMIS measures. Some banks include unique items. In rare instances, a shared item uses different item-level calibrations in each bank.
- PROMIS-Ca Bank v1.1 - Physical Function contains 45 items, 33 of which are also in PROMIS Bank v2.0 - Physical Function.
- PROMIS-Ca Bank v1.0 - Fatigue contains 54 items, all of which are from PROMIS Bank v1.0 - Fatigue.
- PROMIS-Ca Bank v1.0 - Anxiety contains 22 items; 20 items from PROMIS Bank v1.0 - Anxiety, and 2 items unique to CaPS in which cancer specific calibrations were used: EDANX09 & EDANX39.
- PROMIS-Ca Bank v1.0 - Depression item bank contains 30 items; 23 items are from PROMIS Bank v1.0 - Depression and 7 items unique to CaPS in which cancer specific calibrations were used: EDANG09, EDANG29, EDDEP02, EDDEP12, EDDEP16, EDDEP38 & EDDEP55.
- PROMIS-Ca Bank v1.1 - Pain Interference contains 35 items; 32 items from PROMIS Bank v1.1 - Pain Interference v1.1 and 3 items unique to CaPS in which cancer specific calibrations were used: PAININ4, PAININ15 & PAININ30.
PROMIS-Cancer (PROMIS-Ca) measures were developed by having content experts review the adult PROMIS item banks for anxiety, depression, fatigue, pain interference, and physical function. Items were selected through expert consensus and informed by focus groups and cognitive interviews with cancer patients. Multidisciplinary clinical input was obtained to ensure content coverage and the relevance of PROMIS items to patients’ cancer and/or cancer treatment experiences. Items’ psychometric properties were reviewed when applicable. Next, calibration testing was conducted with cancer patients with different diagnoses and treatments. Data were analyzed to identify if items performed differently in people with cancer than people with other chronic conditions or in the general population. In most cases, PROMIS calibrations (“PROMIS Wave 1”) were retained. In rare cases where differential item functioning was identified, calibrations for that item were revised for when that item is used in the PROMIS-Ca item bank. For items that exist only in a PROMIS-Ca item bank, new calibrations were created by using a fixed parameter linking strategy. This set of calibrations is named “Cancer” in the HealthMeasures Scoring Service and Assessment Center.
A fixed parameter linking approach was taken because of the additional analyses that were conducted to evaluate the differences between the PROMIS item bank and the PROMIS-Ca item bank. The 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, www.prosettastone.org/ ), 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 general population PROMIS calibrations when assessing individuals with cancer.
