Spanish translation and validation of a hybrid, health‐related quality of life questionnaire for chronic esophageal conditions: NEQOL‐S

Abstract

Background: Chronic esophageal conditions (CEC) are associated with significant disease-related burden, disability, and costs. Health-related quality of life (HRQOL) constructs are intended to capture the physical, mental, social, and emotional aspects of a patient's life and how health status impacts these domains. The Northwestern Esophageal Quality of Life (NEQOL) can be used among esophageal diseases while maintaining sensitivity to specific conditions. We aimed to translate, cross-cultural adapt, and validate the NEQOL into Spanish.Methods: After language and cross-cultural adaptation, the NEQOL was applied to an outpatient clinic-based population in a single tertiary center. We analyzed the internal consistency, construct, criterion validity, and test-retest reliability of the questionnaire. The criterion validity was tested against the SF-12 questionnaire. Key Results: After completing the translation process, no item was considered problematic. A total of 385 patients were included in the validation study. The internal consistency (Cronbach's alpha) for the total NEQOL-S score was 0.89. The NEQOL-S questionnaire showed moderate test-retest reliability (ICC = 0.828; 95% CI 0.755-0.881; p < 0.001). Criterion validity showed good coherence when correlated with the SF-12 survey (R 2 = 0.538; 95% CI 0.491-0.585, p < 0.001). Conclusions and Inferences:The translated and cross-culturally adapted NEQOL-S showed good psychometric properties that allow its use in Spanish-speaking patients suffering from CEC.

Influence of pelvic floor disorders on quality of life in women

“…On the other hand, although a clinical evaluation of pelvic floor dysfunction was not carried out through clinical diagnostic means, the instruments used were questionnaires validated ( 35 , 37 ) in a population similar to that of our study and are widely accepted on an international level as instruments to detect possible pelvic floor dysfunction ( 41 – 43 ). Likewise, all the other instruments used to measure the different parameters have been validated and previously used in a population similar to that of this study ( 39 , 44 – 46 ).…”
