Validation of the arabic version of the eortc QLQ-C15-PAL questionnaire in cancer patients

Article type: Published abstract


Introduction: Introduction: Quality of life is an important outcome in cancer care and needs assessment by a valid questionnaire. Objectives: Evaluate the psychometric properties of the Arabic version of EORTC QLQ-C15-PAL Methods: A cross sectional study of a convenient sample of inpatients with cancer. Results: 170 patients completed the questionnaire. Cronbach's coefficient met the 0.7 alpha criterion. Confirmatory Factor Analysis met the goodness of fit criteria; GFI, CI, NFI and NNFI>0.90 and RMSEA<0.06. All item-scale correlation coefficients exceeded the set value of 0.40, indicating satisfactory convergent validity. In terms of discriminant validity, all items in the questionnaire showed a higher item-scale correlation more than item-other scale correlation, except for items 1 and 2 (physical function scale) showed a higher correlation with fatigue. 86.4% correlation tests were successful in terms of item discrimination. Construct validity was tested by item inter scale correlation coefficient. All constructs had correlation coefficient <0.70. The strongest correlation were found between physical symptoms and fatigue (r=0.60). Known group method analysis was used to compare scores of patients who had metastasis and who did not have metastasis. Significant differences (P value <0.05) were found in all scales except item 9. Age groups were compared and showed significant differences for physical function, fatigue and global score of quality of life. Conclusions: Arabic version of the EORTC QLQ-C15-PAL is valid and reliable. (Table Presented).
