Filipino Version of the M. D. Anderson Symptom Inventory: Validation and Multisymptom Measurement in Cancer Patients

Abstract Assessing cancer-related symptoms requires a brief, reliable, valid, and culturally adapted symptom screening tool. In the Philippines, cancer patients ( n =206) and community-dwelling adults ( n =170) participated in a cross-sectional validation study of the Filipino version of the M. D. Anderson Symptom Inventory (MDASI-F). Both exploratory factor analysis and hierarchical cluster analysis revealed two underlying symptom severity constructs—general and gastrointestinal symptoms—consistent with the English, Japanese, and Chinese versions of the MDASI. Cronbach alpha coefficients of 0.79 and 0.77, respectively, demonstrated acceptable internal consistency for the two factors. Known-group validity was confirmed by significant differences on MDASI-F items by performance status ( P P
