SAMBO-14: A tool for measuring satisfaction of cancer patients receiving ambulatory chemotherapy

Abstract

Purpose: Design and validation of an instrument measuring the satisfaction of patients receiving ambulatory cancer therapy in a day hospital. Methods: Descriptive cross-sectional study involving the administration of a questionnaire to a sample of 148 cancer patients seen in an ambulatory setting at Hospital Costa del Sol, Marbella (Spain). The validity, internal consistency and reproducibility of the instrument’s items were analysed. Results: In the item-scale correlation, the coefficients obtained were above the adequacy threshold of 0.30. Results showed that the principal components factor analysis was appropriate based on a KMO value of 0.91 and a p<0.001 for Bartlett’s sphericity test. The internal consistency analysis established Cronbach’s alpha coefficients >0.70. A test-retest analysis revealed absolute percentage agreements greater than 90% for all items and kappa point estimates ranging from 0.52 to 0.93. Conclusions: The results obtained show that the questionnaire is, a priori, a reliable and valid instrument for use in Spanish language.
