Cross-cultural rating of satisfaction with cancer care.

Abstract

e17613 Background: Accurate evaluation of patient satisfaction is an important dimension of quality of cancer screening and treatment. We applied ordinal logistic regression to assess uniform, non-uniform and total Differential Item Functioning (DIF) for the Patient Satisfaction with Cancer-related Care (PSCC) measure items in English vs. Spanish speaking cancer patients. Methods: The sample included 18 to 86 years old patients who completed the PSCC in English (N = 1067; 82.5% female) and Spanish (N = 229; 100% female 100%). We used total scale score and latent satisfaction estimate separately as matching variable to assess uniform, non-uniform, and total DIF for the PSCC items using ordinal logistic regression analysis. We used language as the grouping variable, i.e., the English speaking group is the reference group and the Spanish speaking group the focal group. Results: Using the total scale score (TSS), we found uniform DIF for 10 out of 29 PSCC items. For example, item 1 showed uniform DIF (χ2 = 5....
