INTRODUCTION: Chemotherapy-induced nausea and vomiting is a serious complication of cancer treatment that compromises patients' quality of life and treatment adherence, which necessitates regular assessment. Therefore, there is a need to assess patient-reported nausea and vomiting using a validated scale among Arabic speaking cancer patient population. The objective of this study was to translate and validate the Functional Living Index-Emesis (FLIE) instrument in Arabic, a patient-reported outcome measure designed to assess the influence of chemotherapy-induced nausea and vomiting on patients' quality of life. METHODS: Linguistic validation of an Arabic-language version was performed. The instrument was administered to cancer patients undergoing chemotherapy in a tertiary hospital's cancer center in Saudi Arabia. RESULTS: One-hundred cancer patients who received chemotherapy were enrolled. The participants' mean age was 53.3 ± 14.9 years, and 50% were female. Half of the participants had a history of nausea and vomiting with previous chemotherapy. The Cronbach coefficient alpha for the FLIE was 0.9606 and 0.9736 for nausea and vomiting domains, respectively, which indicated an excellent reliability for the Arabic FLIE. The mean FLIE score was 110.9 ± 23.5, indicating no or minimal impact on daily life (NIDL). CONCLUSIONS: The Arabic FLIE is a valid and reliable tool among the Arabic-speaking cancer population. Thus, the Arabic version of the FLIE will be a useful tool to assess the quality of life among Arabic speaking patients receiving chemotherapy. Additionally, the translated instrument will be a useful tool for future research studies to explore new antiemetic treatments among cancer patients.
