Background We provided preliminary psychometric data for the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire–Head and Neck Module, updated version (QLQ-H&N43) from a group of Serbian laryngectomized patients. Methods The study included 170 subjects. The QLQ-H&N43 is a 43-item questionnaire, with 12 multi-item scales and 7 single-item symptom scales. All subjects also completed the Quality of Life Questionnaire-Core 30-questions (QLQ-C30). Results Good internal consistency (Cronbach's α of above 0.7) was found for 5 of the 7 scales. All QLQ-H&N43 scales correlated negatively as predicted with all QLQ-C30 functioning scales. The correlations wi…
International validation of the revised European Organisation for Research and treatment of cancer head and neck cancer module, the EORTC QLQ-HN43
2019
Background: We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ-HN43). Methods: We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test–retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known-group comparisons. Results: Cronbach's alpha was >0.70 in 10 of the 12 multi-item scales. All standardized factor loadings exceeded…
