Women with breast cancer experience a wide spectrum of symptoms after diagnosis and treatment. Symptoms experienced by this specific population might not be fully assessed using available traditional Chinese-language symptom measures.
The aim of this study was to examine the latent constructs and psychometric properties of the Chinese Breast Cancer Prevention Trial (C-BCPT) Symptom Scale.
Two hundred women with breast cancer were recruited in Taiwan. Psychometric properties, including construct validity, internal consistency, and test-retest reliability, of the C-BCPT Symptom Scale were tested after translating the original instrument.
A 21-item C-BCPT Symptom Scale, with 7 extracted factors accounting for 72.26% of the total variance, resulted from an exploratory factor analysis. Construct validity was confirmed by significant correlations between scores on the C-BCPT Symptom Scale and the Taiwan-version Short Form-36 Health Survey (r = -0.49 to -0.53)/Greene Climacteric Scale (r = 0.81). Reliability coefficients for the overall scale/6 extracted factors (Cronbach's α = 0.72-0.88) and test-retest reliability (intraclass correlation coefficients = 0.77-0.94) of the translated instrument were satisfactory, whereas 1 reliability coefficient for 1 extracted factor was inadequate (Cronbach's α = 0.57).
An interpretable structure with preliminary acceptable psychometric properties of the C-BCPT Symptom Scale was obtained; the C-BCPT can help traditional Chinese-speaking healthcare professionals perform adequate assessments of the symptoms experienced by women with breast cancer.
The C-BCPT Symptom Scale can be used in clinical practice and research to assess symptoms experienced by this specific population or effects of related interventions.
乳腺癌患者在诊断和治疗后会经历广泛的症状。使用现有的繁体中文症状测量工具可能无法充分评估这一特定人群所经历的症状。
本研究旨在检验中文乳腺癌预防试验（C-BCPT）症状量表的潜在结构和心理测量特性。
在台湾招募了 200 名乳腺癌患者。在翻译原始工具后，对 C-BCPT 症状量表的心理测量特性进行了检验，包括结构有效性、内部一致性和重测信度。
通过探索性因子分析，得出一个 21 项的 C-BCPT 症状量表，7 个提取因子可解释总方差的 72.26%。结构有效性通过 C-BCPT 症状量表得分与台湾版简易 36 健康调查（r = -0.49 至-0.53）/格林绝经量表（r = 0.81）之间的显著相关性得到确认。翻译后仪器的总体量表/6 个提取因子（Cronbach's α = 0.72-0.88）和重测信度（组内相关系数= 0.77-0.94）的可靠性系数令人满意，而 1 个提取因子的 1 个可靠性系数不足（Cronbach's α = 0.57）。
获得了 C-BCPT 症状量表具有可解释结构和初步可接受的心理测量特性；C-BCPT 可以帮助讲繁体中文的医疗保健专业人员对乳腺癌患者所经历的症状进行充分评估。
C-BCPT 症状量表可用于临床实践和研究，以评估特定人群所经历的症状或相关干预措施的效果。
