Measure
Preference-tailored (PT) Intervention
Standard Information: A computer based educational overview of CRC and CRC test options was presented to the subject. The subject was given a handout with a brief description of each of the screening options and which included the test that they have chosen as their preferred test. The subjects were asked to take this handout to their upcoming clinic appointment and to discuss the screening options with their care provider. Preference-tailored Information: A preference elicitation exercise generated a list of the three top attributes for the subject and the CRC screening test most consistent with these attributes. Subjects were provided with a handout to take to their clinic appointment as were the Standard Information group, but with the addition of a listing of their top attributes and the test most consistent with their top attributes.

Usual Care
Due to budget and time constraints this group is not powered as a true study arm but is being used to assess the impact of our baseline physician information letter and to control for any other interventions of system-wide initiatives that may have occurred during the study timeframe and impact rated of CRC screening.

Outcome measures measuring decisional satisfaction using 7-item scale categorized into low, moderate, high. Decisional satisfaction is a measure that was first developed by Margaret Holmes Rover and colleagues (Med Decis Making. 1996 Jan-Mar;16(1):58-64) to assess the perspective of a patient involved in a medical decision with the decision making process. The measure includes questions related to overall satisfaction, and satisfaction with the amount of information received, involvement in, degree of consistency with values, and time to make the decision. The measure includes 5 questions each on a 5 point scale where higher scores = higher satisfaction. When scaled into one overall measure of decision satisfaction, lower scores = lower satisfaction and higher scores = higher satisfaction.
