PSYCHOMETRIC PROPERTIES OF THE SPANISH VERSION OF BREAST CANCER AND LYMPHEDEMA SYMPTOM EXPERIENCE INDEX

Abstract

Background: Lymphedema is a common late and chronic adverse effect of breast cancer treatment. This study aimed to translate and evaluate the psychometric properties of the BCLE-SEI Spanish version with Spanish-speaking breast cancer patients. Method: 286 patients were recruited (2018 to 2020), from the Hospital Universitario Central de Asturias. Data analysis included descriptive statistics; internal consistency and test-retest reliability; principal component analysis and exploratory factor analysis; average variance extracted; and receiver operating characteristic curves. Results: No semantic modifications to items were needed. The scores of the instrument demonstrated excellent internal consistency (Cronbach’s alpha = .95-.97; McDonald’s omega = .96-.98) and test-retest reliability (r = .78-.87, n = 29). A significant difference was observed between the lymphedema group and non-lymphedema group (p

Antecedentes: el linfedema es una complicación tras el cáncer de mama. El objetivo fue evaluar las propiedades psicométricas de la versión española BCLE-SEI en mujeres diagnosticadas de cáncer de mama que hablaban español. Método: participaron 286 pacientes (2018 a 2020) del Hospital Universitario Central de Asturias. El análisis de datos incluyó estadísticos descriptivos; consistencia interna y fiabilidad test-retest, análisis de componentes principales y análisis factorial exploratorio; varianza media extraída; y curvas de características operativas del receptor. Resultados: no se necesitaron modificaciones semánticas en los ítems. El instrumento demostró excelente consistencia interna (alfa de Cronbach = 0,95-0,97; omega de McDonald = .96-.98) y fiabilidad test-retest (r = 0,78-0,87; n = 29). Se observaron diferencias significativas entre grupos linfedema y sin linfedema (p
