焦虑敏感指数—3中文版在乳腺癌患者中的应用

Reliability and Validity of the Chinese Version of Anxiety Sensitivity Index-3(ASI-3) in Chinese Women with Breast Cancer

目的:评估焦虑敏感指数-3(ASI-3)中文版在乳腺癌患者中使用的信度和效度。方法:用焦虑敏感指数-3(ASI-3)和汉密尔顿焦虑量表(HAMA)对676名女性乳腺癌患者施测,初测两周后,从原样本中随机抽取50名女性进行重测。结果:全量表的Cronbach’sα系数为0.94,3个分量表的Cronbach’sα系数在0.91-0.93之间;全量表的重测信度为0.86,3个分量表的重测信度在0.67-0.80之间;全量表条目间平均相关系数为0.49,3个分量表条目间平均相关系数在0.64-0.69之间。验证性因子分析各指标:CFI(0.941),NFI(0.929),TLI(0.929),RMSEA(0.083)均符合测量学要求,支持量表三因素模型的理论构想。焦虑敏感指数得分与焦虑症状之间显著正相关。结论:ASI-3具有很好的信度和效度,是评估我国女性乳腺癌患者焦虑敏感的可靠工具。

Objective： To assess the reliability and validity of the Chinese version of Anxiety Sensitivity index-3 in Chi- nese women with breast cancer. Methods： The ASI-3 and HAMA were administrated to 676 women with breast cancer, and two weeks later, the ASI-3 was retested among 50 women sampling from the original sample. Results： The Cronbach＇s ct coefficient for the total scale was 0.94 and for the three subscales were ranged from 0.91-0.93; The two-week test-retest coefficient was 0.86 for the total scale and were from 0.67-0.80 for the subscales; The mean inter-item correlation coeffi- cient for the total scale was 0.49, and for the three subscales were ranged from 0.64-0.69. Results of confirmatory factor analysis such as CFI（0.94）, NFI（0.929）, TLI （0.929）, RMSEA（0.083） confirmed the original three-factor model. Conclusion： The ASI-3 has good psychometric quality, which can be applied to assess anxiety sensitivity in Chinese women with breast cancer effectively.
