PRIMARY outcome

Population: Intention to treat

SECONDARY outcome

Timeframe: Immediate post-intervention study visit

Knowledge was assessed at baseline (pretest) and at the time of the exit survey (posttest) based on responses to a 12-item questionnaire (True/False/Don't know) that inquired about CRC risk factors, the rationale and goals of screening, and age at which screening should begin. Cumulative knowledge scores (range, 0-12) were derived by summing correct responses to the 12 individual knowledge questions.

SECONDARY outcome

Timeframe: Immediate post-intervention primary care provider (PCP) visit

Patient satisfaction with the decision-making process (SDMP) was assessed using the validated 12-item Satisfaction with the Decision-Making Process scale. Five ordered response categories were used for each item. Each response was assigned a point score ranging from 1 for "strongly disagree" (or "poor") to 5 for "strongly agree" (or "excellent"). A cumulative score was calculated based on the summed response scores for each item (maximum score = 60). Mean item substitution was used to impute missing data.

SECONDARY outcome

Timeframe: Immediate post-intervention study visit

Screening intentions were also assessed as part of the posttest. Subjects were asked how sure they were that they would schedule an appointment to get screened for colorectal cancer and how sure they were that they would complete the screening test they scheduled. An ordered 5-point response frame was used ranging from 1 for "not at all sure" to 5 for "completely sure".
