Researchers are assessing the reliability and validity of the National Cancer Institute’s (NCI) Colorectal Cancer Screening (CRCS) survey by administering it to 1,200 patients aged 51–74 years attending primary care practices in Houston. Participants’ answers to survey questions and data in their medical record are being compared to patients who have one or more CRCS test recorded in their medical file and those who have none. The survey will be administered by mail, by telephone, or in person, and validity will be analyzed overall, by method of administration, and by income level, education level, and race or ethnicity of the participants. The reliability of the survey will be evaluated by repeating administration 6-months later to 150 participants. The quality of responses will be assessed by examining survey completion rates; unanswered questions; method of administration; income, education, and race or ethnicity of participants; and by conducting qualitative interviews with a subset of respondents.
