Reliability and Validity Research of Chinese Version of Cancer Appetite and Symptom Questionnaire

Objective To investigate the reliability and validity of the Chinese version of cancer appetite and symptom questionnaire(CASQ).

Methods CASQ Chinese questionnaire was formed using translation and back-translation, and performed on 88 cancer patients. The entry distinction of the Chinese version of CASQ was tested. Simultaneously, PG-SGA was used to assess nutritional risks of the subjects; and it was compared with CASQ as well as the validity was tested. After the first measurement, the second measurement was made 7 days later; the reliability study of both CASQ was conducted.

Results The correlation coefficient between each entry score of CASQ and the total score of the questionnaire was 0.242-0.653(P < 0.05). The result of re-test reliability coefficient showed the data were good, the result of half-reliability was 0.560, internal consistency reliability coefficient was 0.436, and the r_s value of the Chinese version of CASQ total score and the PG-SGA total score was -0.475.

Conclusion The Chinese version of CASQ is tested to be with good reliability and validity.
