Little is known about the impact of risk assessment tools on decision-making by patients and clinicians. In particular, even though the NCI Colorectal Cancer Risk Assessment Tool is one of the most prominent risk assessment tools available, no study has quantified its usability or impact on decision-making or uptake of screening. In this study, we will measure patients' satisfaction with the NCI CRC RAT, their perception of its usability and helpfulness, and its impact on their decision-making and behavior. In addition, we will assess the impact of adding information about their chance of having an advanced adenoma.

Condition Intervention
Colorectal Cancer
Behavioral: Patient views NCI CRC RAT
Behavioral: View presentation regarding current chance of having an advanced adenoma

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Patients' Opinions and Responses to the National Cancer Institute's Colorectal Cancer Risk Assessment Tool

Primary Outcome Measures:
  • Satisfaction with NCI CRC RAT [ Time Frame: 1 day ]
    19 Likert-scale questions regarding usability of and satisfaction with the questions asked by the website to assess individual risk and the information provided

  • Perceived risk of developing CRC [ Time Frame: 1 day ]
    Six Likert-scale questions regarding the subject's perceived risk of developing CRC in next 5 years, 10 years, and lifetime, and compared to others of same age and gender.

  • Intent to be screened within six months [ Time Frame: 6 months ]
    Three multiple-choice questions regarding intent to be screened in next six months in general or with colonoscopy or stool testing. (Answer options: Definitely, Probably, Probably not, and Definitely not)

  • Stage of readiness to screen [ Time Frame: 1 day ]
    Measure calculated from patient's answers on 5 multiple-choice or Likert-scale questions

  • Preferred CRC screening test [ Time Frame: 1 day ]
    Answer on a single multiple choice question, offering options of colonoscopy, stool test, or other.

Secondary Outcome Measures:
  • Uptake of CRC screening [ Time Frame: 6 months after intervention ]
    Phone call follow up and check of medical record.
