  2. a adjusted for age, gender, marital status, education, economic status, trait anxiety, bowel symptoms, family history of CRC, and past FOBT screening. b correct vs. else. c yes vs. not.
  3. For the scales, the OR estimate the change in odds of intention that is associated with a change of one scale point.
  4. The OR described the associated of each psychosocial variable and intention respectively.
