Reliability and Validity of Amharic Version of EORTC QLQ-C 30 Questionnaire among Gynecological Cancer Patients in Ethiopia

<div><p>Background</p><p>Cancer is a growing public health problem worldwide. The focus of cancer treatment, in addition to curation, is improving the quality of life (QOL). This study aimed to assess the reliability and validity of Amharic version of European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) among gynecological cancer patients in Ethiopia.</p><p>Methods</p><p>A facility-based cross-sectional study was conducted using the Amharic version of EORTC QLQ-C30 on 153 gynecological cancer patients in Tikur Anbassa Specialized Hospital (TASH), Addis Ababa, Ethiopia. Descriptive statistics, correlation analysis and multivariable linear regression were employed in statistical analysis.</p><p>Results</p><p>The Amharic version of EORTC QLQ-C30 had a Cronbach’s α value of 0.81. The internal consistency for each domain of EORTC QLQ-C30 was also acceptable (Cronbach’s α >0.7) except for cognitive function domain (Cronbach’s α = 0.29). Stepwise multivariable linear regression analysis showed that emotional functioning (p<0.001), fatigue (p<0.001) and social functioning (p = 0.004) were the determinative scales of EORTC QLQ-C30 on global health status (GHS). The clinical validity test (Known group validity) showed that there were significant differences in score for twelve out of 15 domains, between surgery and radiation scheduled patients. All items of emotional function, role function, fatigue, and GHS meet the discriminate validity criterion.</p><p>Conclusion</p><p>The Amharic version of EORTC QLQ-C30 found to be reliable and had an acceptable validity to assess the QOL for gynecological cancer patients. We recommend further work on the validity and responsiveness of the EORTC QLQ-C30 with stronger design.</p></div
