Before-and-after changes in outcome measures across treatment groups

SCORE	CONTROL GROUP (n = 95)		INTERVENTION GROUP (n = 103)		P VALUE*
	MEAN (SD) CHANGE	MEDIAN (RANGE) CHANGE	MEAN (SD) CHANGE	MEDIAN (RANGE) CHANGE
	Intention to be screened†	0.07 (0.6)	0 (−1 to 2)	0.13 (0.7)		0 (−1 to 2)	.58
Risk‡	0.08 (0.6)	0 (−2 to 3)	0.08 (0.7)	0 (−4 to 3)	.48
Risk relative to others‡	0.04 (0.4)	0 (−1 to 2)	0.11 (0.8)	0 (−4 to 4)	.65
Worry§	0.07 (0.4)	0 (−1 to 3)	0.05 (0.4)	0 (−1 to 2)	.46

^*Mann-Whitney-Wilcoxon test was used.

^†The intention score was the average of responses to 2 items: I intend to undergo colorectal screening (completing fecal occult blood tests, flexible sigmoidoscopy, or colonoscopy); and I do not intend to go through colorectal screening (fecal occult blood tests, flexible sigmoidoscopy, or colonoscopy) (reverse coded). These items were measured using a 4-point Likert scale from strongly disagree (score of 1) to strongly agree (score of 4).

^‡Participants were asked about their perceived absolute and comparative (ie, self-compared with others) risk of getting colorectal cancer (score 0 to 4). Possible responses were much below average, below average, average, above average, and much above average.

^§Participants were asked, “How worried are you about getting colorectal cancer?” Possible responses were not at all worried (score of 1), slightly worried, moderately worried, and quite worried (score of 4).
