Transcultural adaptation of the user satisfaction scale to the health service: Brazilian version of the EORTC IN-PATSAT32 questionnaire

Abstract

Objective To describe the cross-cultural adaptation and psychometric properties of the Brazilian version of the INPATSAT32 questionnaire. Methods The questionnaire was applied to 328 patients in a public hospital, and the retest was performed with 86 patients, approximately 1 week after the test. Psychometric analyses were performed to evaluate the structure, reliability, and internal consistency of the questionnaire. Results The adapted questionnaire presented high sensitivity and the intraclass correlation coefficient (ICC [8) indicated strong convergent validity and discriminant properties of the instrument, as well as high internal consistency (Cronbach’s a[0.8). Exploratory factor analysis divided the questionnaire into five dimensions: satisfaction with a multidisciplinary team (a = 0.953, kp = 0.61, ICC = 0.953), doctors (a = 0.993, kp = 0.817, ICC = 0.966), therapeutic (a = 0.946, kp = 0.869, ICC = 0.972), hospital structure (a = 0.97, kp = 0.87, ICC = 0.947), and hospital discharge. Conclusion The results indicated that the Brazilian version maintained its psychometric properties when used in a heterogeneous population and with different diagnoses and stages of treatment for cancer.
