Abstract
Health related quality of life (HRQOL) is an important outcome in cancer care and needs assessment by a valid questionnaire. HRQOL questionnaires need to be validated after translations to other languages and cultural settings. The purpose of this study is to evaluate the psychometric properties of the Arabic version of the European Organization for Research and Treatment of Cancer Quality of Life 15 items Questionnaire for Palliative Care (EORTC QLQ-C15-PAL).This is a cross-sectional study of a convenient sample of inpatients with cancer.One hundred seventy-five patients completed the EORTC QLQ-C15-PAL questionnaire. Cronbach’s alpha coefficient met the 0.7 alpha criterion. Confirmatory factor analysis met the goodness of fit criteria; goodness-of-fit index (GFI), comparative fit index (CFI), normed fit index (NFI) and non-normed fit index (NNFI) >0.90 and root mean square error of approximation (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 than item-other scale correlation, except for items 1 and 2 (physical function scale) that showed a higher correlation with fatigue. Construct validity was tested by item inter scale correlation coefficient. All constructs had correlation coefficient <0.70. External validity was tested by comparison of scores of patients who had metastasis and who did not have metastasis. Significant differences (P value <0.05) were found in all scales except for nausea. Age groups were compared and showed significant differences for physical function, fatigue, and global score of HRQOL.The Arabic version of the EORTC QLQ-C15-PAL is valid and reliable.
