Participants in the National Surveys of Colorectal Cancer Screening Practices have
included primary care physicians (in general practice, family practice, internal
medicine, and obstetrics/gynecology), specialty physicians (gastroenterologists, general
surgeons, and diagnostic radiologists), and health plan medical directors. Questionnaires
have been administered by mail, telephone, fax, or the Internet. Statistical analyses have
included descriptive statistics, contingency tables, and logistic regression. Sampling
weights are applied to permit generalization of results to the US population.
