Reliability and Validity of the EORTC QLQ-CIPN20 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20-Item Scale) among Thai Women with Breast Cancer Undergoing Taxane-Based Chemotherapy.

Objective: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20-item scale (EORTC QLQ-CIPN20) is the common method for determining taxane-induced peripheral neuropathy (TIPN) symptoms. However, there have been no studies on the psychometric properties of the Thai Version of EORTC QLQ-CIPN20. The aim of this study was to evaluate the test-retest reliability, concurrent validity, and contrasting group validity of the Thai Version of EORTC QLQ-CIPN20 among women with breast cancer who received taxane-based chemotherapy.
