The patients were divided into two groups: group I, with 20 patients showing positive result in the questionnaire, and group II, with 20 people showing negative result in the questionnaire. Colonoscopy was considered positive when presenting neoplasm or its precursor. the result was statistically analyzed by Fischer's exact test and sensitivity calculation. Results: The results showed 14 positive and 26 negative colonoscopies. Group I had 9 positive and 11 negative colonoscopies and Group II, 5 positive and 15 negative (p=0.20) colonoscopies. The questionnaire presented sensitivity of 64.2%. Conclusion: The use of this questionnaire based on signs and symptoms of CCR alone was not effective in CCr screening.
