The aim of this study was to modify and test the Chinese version of the Revised Illness Perception Questionnaire to measure the illness perception of breast cancer-related lymphedema among breast cancer survivors. Before the investigation, identity and causal subscales were modified and the wording of the remaining scales was also adjusted. The psychometric properties of this instrument was evaluated using the technique of explore and confirmatory factor analysis. Data from 203 breast cancer survivors was entered into factor analysis. Five causal factors were extracted after removing one item, accounting for 68.02% of the variance in total. An acceptable fit with the data for the proposed seven-factor model was obtained after eliminating three items and resetting seven error covariances. The Cronbach's α values and composite reliability coefficients were acceptable. This measurement is reliable and valid for measuring illness perceptions of breast cancer-related lymphedema in Chinese breast cancer survivors. It could be helpful for further studies that examine the effect of illness perceptions on health-related behaviours, such as lymphedema risk-reduction behaviours in the Chinese cultural context.
本研究旨在修订并测试中文版修订疾病认知问卷，以测量乳腺癌幸存者对乳腺癌相关淋巴水肿的疾病认知。在调查之前，对身份和病因分量表进行了修订，并对其余分量表的措辞进行了调整。使用探索性和验证性因素分析技术对该工具的心理测量特性进行了评估。将203名乳腺癌幸存者的数据纳入因素分析。剔除一个项目后提取出五个病因因素，占总方差的68.02%。在剔除三个项目并重新设定七个误差协方差后，所提出的七因素模型与数据拟合良好。克朗巴赫α值和组合信度系数均可接受。该测量方法对于测量中国乳腺癌幸存者对乳腺癌相关淋巴水肿的疾病认知是可靠且有效的。它有助于进一步研究疾病认知对健康相关行为的影响，例如在中国文化背景下的淋巴水肿风险降低行为。
