Abstract
Background: Despite being a widely used generic measure of health-related quality of life worldwide, there is limited evidence on the psychometric properties of the EuroQoL Five-dimensions five level (EQ-5D) among cervical cancer patients in Ethiopia.
Objective: To evaluate psychometric properties of the Amharic version of EQ-5D among Ethiopian cervical cancer patients.
Methods: A longitudinal survey of cervical cancer patients receiving treatment at two Ethiopian tertiary care facilities was conducted from March 2022 to July 2023. Participants completed the EQ-5D and the European Organization for Research and Therapy of Cancer (EORTC QLQ-C30) at baseline and after three months on treatment. Effect size and standardized response mean were used to assess responsiveness. Anchor-based and distribution-based methods were used to calculate the minimal clinically important difference (MCID). Minimal detectable change (MDC) ratios were computed at the individual and group levels. Statistical significance was determined at p < 0.05.
Results: Three hundred seventy-one patients completed the survey at baseline and follow-up with a mean age of 49.72 (10.80) years. The majority (268,73%) of the patients had early-stage cancer. The EQ-5D index and EQ VAS scores respectively improved by 0.04 and 7.0 post-treatment.The physical domains of EORTC QLQ-C30 had showed high correlation with physical dimensions of EQ-5D (r > 0.6) and the instrument showed good discriminate validity between patients with different health states. The effect size ranged between - 0.12 and 0.60 for the EQ-5D index value and - 0.12 to 1.16 for the EQ VAS, indicating small to large responsiveness. The average (range) MCID value of the EQ-5D index was 0.10-0.15. The findings showed that MCID to MDC ratios at the group level were more clinically meaningful than the individual level.
Conclusion: The EQ-5D effectively detected changes and discriminate patients with different levels of health. While group-level MCIDs were established in this study, further studies are recommended to prove its usefulness at the individual-level.
期刊介绍：
Health and Quality of Life Outcomes is an open access, peer-reviewed, journal offering high quality articles, rapid publication and wide diffusion in the public domain.
Health and Quality of Life Outcomes considers original manuscripts on the Health-Related Quality of Life (HRQOL) assessment for evaluation of medical and psychosocial interventions. It also considers approaches and studies on psychometric properties of HRQOL and patient reported outcome measures, including cultural validation of instruments if they provide information about the impact of interventions. The journal publishes study protocols and reviews summarising the present state of knowledge concerning a particular aspect of HRQOL and patient reported outcome measures. Reviews should generally follow systematic review methodology. Comments on articles and letters to the editor are welcome.
