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 < .001) in terms of total scale, symptom occurrence (p < .001), symptom distress in the physical-functional (p < .001), and psychosocial dimension (p < .001). Principal component analysis for symptom occurrence revealed a unidimensional factor and two factors were identified for symptom distress via exploratory factor analysis, the two of which explained 45.71% and 54.77% of the total sample variance, respectively. CONCLUSIONS This study provided initial evidence to support the psychometric properties of the BCLE-SEI Spanish version.

西班牙版乳腺癌和淋巴水肿症状体验指数的心理测量学特性。

背景淋巴水肿是乳腺癌治疗常见的晚期和慢性副作用。本研究旨在翻译和评估 BCLE-SEI 西班牙语版本的心理测量特性，用于讲西班牙语的乳腺癌患者。方法从阿斯图里亚斯中央大学医院招募了 286 名患者（2018 年至 2020 年）。数据分析包括描述性统计；内部一致性和重测信度；主成分分析和探索性因素分析；提取平均方差；和接受者操作特征曲线。结果 不需要对项目进行语义修改。该仪器的分数表现出出色的内部一致性（Cronbach´s alpha = .95-.97；McDonald´s omega = .96-.98）和重测信度（r = .78-.87，n = 29） . 淋巴水肿组和非淋巴水肿组（p < .001）在总规模、症状出现（p < .001）、身体功能症状困扰（p < .001）和社会心理维度 (p < .001)。症状发生的主成分分析揭示了一个单维因素，通过探索性因素分析确定了症状困扰的两个因素，这两个因素分别解释了总样本方差的 45.71% 和 54.77%。结论 本研究提供了初步证据来支持 BCLE-SEI 西班牙语版本的心理测量学特性。和社会心理维度 (p < .001)。症状发生的主成分分析揭示了一个单维因素，通过探索性因素分析确定了症状困扰的两个因素，这两个因素分别解释了总样本方差的 45.71% 和 54.77%。结论 本研究提供了初步证据来支持 BCLE-SEI 西班牙语版本的心理测量学特性。和社会心理维度 (p < .001)。症状发生的主成分分析揭示了一个单维因素，通过探索性因素分析确定了症状困扰的两个因素，这两个因素分别解释了总样本方差的 45.71% 和 54.77%。结论 本研究提供了初步证据来支持 BCLE-SEI 西班牙语版本的心理测量学特性。
