MAKING A QUESTIONNAIRE CONCERNING THE QUALITY OF LIFE IN COLORECTAL CANCER PATIENTS AFTER SURGERY AND STANDARDIZATION OF THE SCORE

Abstract

　We developed a new instrument for measuring the quality of life in colorectal cancer patients after their operation. Factor analysis indentified five factors. Internal consistency measured by Cronbach's alpha coefficient was 0.86. Next we standardized the outcome in 89 patients,and classified that into three degrees；low,fair,and high quality of life. Although the patients with colostomy have a lower quality of life in most factors than others,they have a higher quality of life（though not significantly higher）in the factor of satisfaction for defecation and urination at 3 months after the operation.
