Abstract: Background　Accurate and effective evaluation of individual health belief characteristics is the premise of effective intervention.Mature scales for evaluating health belief of hypertension，breast cancer and other diseases has been developed in China.As a common malignant tumor，colorectal cancer is a national focus in terms of prevention and control.However，there is no reliable，valid and mature Chinese evaluation scale for health belief of colorectal cancer.Objective　To introduce and translate Colorectal Cancer Health Belief Scale and examine its reliability and validity in Chinese population in order to provide an effective scale for measuring the health belief in patients with colorectal cancer in China.Methods　According to Brislin translation model，we translated the English Colorectal Cancer Health Belief Scale into Chinese version following the forward-translation and back-translation and the Chinese version of Colorectal Cancer Health Belief Scale was cross-culturally adjusted by expert review and a pilot study.A total of 200 relatives of patients with colorectal cancer from the Department of Colorectal Surgery，Cancer Center of Sun Yat-sen University in 2017 completed the scale and we tested its reliability and validity.Results　Six dimensions （36 items），the severity of colorectal cancer，knowledge of the susceptibility to colorectal cancer，the benefits of colorectal cancer screening，the obstacles in colorectal cancer screening，health motivation and self-efficacy of colorectal cancer screening，were included in the Chinese version of Colorectal Cancer Health Belief Scale.The Pearson correlation between item and total score of the scale ranged from 0.349-0.726.The content validity index of the scale （S-CVI） was 0.98.Content validity index of each item （I-CVI） ranged from 0.84 to 1.00.Six common factors were abstracted by principal component analysis and they explained 66.645% of total variance，and each item had a high rotated component matrix （>0.400）． The test-retest reliability was 0.848.The Cronbach's α coefficient of the total scale and its dimensions were 0.881 and 0.801-0.944，respectively.Conclusion　The Chinese version of Colorectal Cancer Health Belief Scale has been proved to be reliable and valid.It is a valuable tool for evaluating health belief of colorectal cancer in mainland China.
