The WATCH (Wellness for African Americans Through Churches) Project was a randomized trial comparing the effectiveness of 2 strategies to promote colorectal cancer preventive behaviors among 587 African American members of 12 rural North Carolina churches. Using a 2 X 2 factorial research design, the authors compared a tailored print and video (TPV) intervention, consisting of 4 individually tailored newsletters and targeted videotapes, with a lay health advisor (LHA) intervention. Results showed that the TPV intervention significantly improved (p < .05) fruit and vegetable consumption (0.6 servings) and recreational physical activity (2.5 metabolic task equivalents per hour) and, among those 50 and older (n = 287), achieved a 15% increase in fecal occult blood testing screening (p = .08). The LHA intervention did not prove effective, possibly because of suboptimal reach and diffusion.
