Trial Outcomes & Findings for Educational CD-ROM Compared With Standard Informed Consent for Patients With Colorectal Cancer or a Family History of Colorectal Cancer (NCT NCT00450424)

NCT ID: NCT00450424

Last Updated: 2014-09-05

Results Overview

10-item true/false MSI knowledge survey developed by the oncologists on trial. (e.g., "Microsatellite Instability is found in every person that has had cancer."; "Microsatellite Instability may be caused by a permanent change in a gene that is inherited from a person's mother or father."). Participants can score anywhere from 0 (no questions answered correctly) to 10 (all questions answered correctly).

CD-ROM Condition
Participants who are randomized to the CD-ROM condition will complete the baseline interview and then meet with the health educator who will provide the participant with the standard MSI consent form and provide a brief, standardized explanation of the MSI test. At that time, the participant can ask any questions s/he wishes to ask. Next, the participant will be provided with the CD-ROM to view on a laptop computer in the clinic. Participants will also be given a copy of the CD-ROM to take home and keep for future reference. The CD-ROM patients will sign (or not sign, if they do not consent or wish to think further about the decision) the consent form after this discussion.
Standard Consent Condition
Participants in the Standard consent condition will complete the baseline interview and then meet with the study health educator who will provide the participant with the standard MSI informed consent form and provide a brief, standardized explanation of the MSI test. At that time, the participant can ask any questions s/he wishes to ask. The patients will either sign (or not sign, if they do not consent to have the test, or wish to think further about the decision) after this discussion. Participants who have further questions will be referred to either the attending physician or the genetics counselor.

SECONDARY outcome

Timeframe: at enrollment and 2 weeks after enrollment

Participants completed a baseline survey upon enrollment to the trial. 2 weeks after baseline, they completed a follow-up survey (assessed at both baseline and FU). Differential impact of CD-ROM on satisfaction with MSI test decision, difficulty making decision \& decisional conflict; attitude; general \& cancer-related distress; discussions with family about MSI test \& familial colorectal cancer risk were measured.

SECONDARY outcome

Timeframe: at enrollment and 2 weeks after enrollment

Participants completed a baseline survey upon enrollment to the trial. 2 weeks after baseline, they completed a follow-up survey (assessed at both baseline and FU). Impact of demographic factors, disease/family history characteristics, family support, and cancer-related distress on satisfaction with and completeness of the informed consent process was measured
