Description
Summary:Background and objectiveAssessing the impact of chemotherapy-induced nausea and vomiting (CINV) on the quality of life (QoL) of cancer patients is critical. However, there is a dearth of specialized assessment tools designed specifically for pediatric cancer patients. The aim of this study was to develop and validate the Pediatrics Functional Living Index-Emesis (PFLIE) as a patient-reported outcome measure (PROM) to assess the impact of CINV on QoL in pediatric patients. This study was approved by the Institutional Review Board of Sun Yat-sen University Cancer Center (Approval No. B2021-113-01) and was conducted in accordance with the Declaration of Helsinki.​Materials and methodsThe reliability, content validity, structural validity, and concurrent validity of the PFLIE were assessed through two rounds of Delphi expert consultation and a questionnaire survey of 90 pediatric cancer patients receiving chemotherapy at a tertiary care hospital cancer center in China.ResultsThe PFLIE consists of two domains: nausea (10 items) and vomiting (10 items). The content validity index (CVI) for both the nausea and vomiting domains was 0.933. The Cronbach’s alpha coefficients for the total scale, nausea domain, and vomiting domain were 0.964, 0.928, and 0.943, respectively. Item-domain correlations were stronger for the PFLIE (r = 0.678-0.882) across domains compared to across-domain correlations (r = 0.493-0.780), suggesting that the PFLIE has acceptable construct validity. In addition, the PFLIE demonstrated acceptable concurrent validity.ConclusionsThe validity and reliability of the Chinese version of the PFLIE are reliable and valid. The tool can help healthcare providers effectively identify and manage CINV symptoms, thereby improving the QoL of pediatric cancer patients. In low- and middle-income countries (LMICs) with limited resources, PFLIE can be used to improve the management of CINV and to ensure that pediatric cancer patients receive adequate care despite inadequate healthcare infrastructures.
