Reliability and Validity of Chinese Version of Illness Cognition Questionnaire in Women with Breast Cancer / 中国康复理论与实践

ABSTRACT

Objective To test the reliability and validity of Chinese version of Illness Cognition Questionnaire(ICQ)in women with breast cancer. Methods From October,2016 to May,2017,297 women with breast cancer were investigated with the Chinese version of the ICQ and Brief Illness Perception Questionnaire(B-IPQ).The reliability and validity of the Chinese version of ICQ were tested. Results The Cronbach's α of three subscales of ICQ(helplessness,acceptance and perceive benefits)were 0.855,0.857, 0.878,and the test-retest reliability of three subscales were 0.946,0.963,0.901(P<0.001).A confirmatory factor analysis was tested,χ2/df=2.500,SRMR=0.063,CFI=0.920.The factor load capacity of each subscales was 0.37 to 0.84 and the correlation of helplessness,acceptance and perceive benefits was-0.49 to 0.81(P<0.001).The correlation coefficient of criterion-related validity of the helplessness subscale of ICP with B-IPQ was 0.727(P<0.001). Conclusion The Chinese version of ICQ has good reliability and validity,which is a valuable research tool in clinical studies of psychological cognition of patients with breast cancer.
