中文版改良疾病感知问卷的修订及其在乳腺癌患者中的信效度检验

Revision of Chinese Version of the Illness Perception Questionnaire- Revised and Its Reliability and Validity Test Among Breast Cancer Patients

目的探讨修订的中文版改良疾病感知问卷(IPQ-R)在乳腺癌患者中的适用性,并检验其信效度。方法采取方便抽样法,选取2013年4月—2014年2月中山大学附属肿瘤医院收治的213例乳腺癌患者,进行中文版IPQ-R测量,对中文版IPQ-R的症状识别维度和病因维度进行修订。选取30例患者3周后进行问卷的重测,进行信效度检验。结果修订的中文版IPQ-R在乳腺癌患者中具有较好的信效度:该问卷各维度(除症状识别维度)的Cronbach'sα系数均大于0.60;重测信度的ICC值均大于0.50;症状识别维度各条目的条目水平的内容效度指数(I-CVI)值均大于0.80,病因维度各条目的 I-CVI值均不低于0.78;病因维度的探索性因子分析显示各条目的因子负荷均大于0.40。结论修订的中文版IPQ-R在乳腺癌患者中具有较好的信效度,可以作为乳腺癌患者疾病感知的测量工具。

Objective To investigate the applicability of the Chinese version of the Illness Perception Questionnaire-Revised（ IPQ-R）among patients with breast cancer and test its reliability and validity. Methods Using convenience sampling method,enrolled 213 patients with breast cancer who were admitted into the Affiliated Tumor Hospital of Sun Yat-sen University from April 2013 to February 2014. Evaluation was conducted using the Chinese version of IPQ-R. Symptom recognition dimension and cause dimension in the Chinese version of IPQ-R were revised. Then selected 30 patients to undertake IPQ-R evaluation again three weeks later. Results After revision,the Chinese version of IPQ -R showed superior reliability and validity;the Cronbach＇s of all the dimensions（ except recognition dimension ）was above 0. 60;the ICC of test-retest reliability was above 0. 50;I-CVI of each item in the recognition dimension was above 0. 80,and I-CVI of each item in the cause dimension was not lower than 0. 78;the exploratory factor analysis showed that the factor loading of each item in cause dimension was greater than 0. 40. Conclusion The revised Chinese version of IPQ-R is superior in reliability and validity among patients with breast cancer and could be employed as the measuring tool for breast cancer patients＇illness perception.
