“A web-based tailored health behavior intervention for African American colon cancer survivors.”

Racial disparities in colon cancer incidence and mortality, and the fact that health behaviors, such as diet and physical activity, are likely related to colon cancer prognosis, survival, and other forms of co-morbidity argue for interventions encouraging adoption of healthy behaviors in African American colon cancer survivors. However, there have been surprisingly few empirically tested health behavior interventions in this population. We will conduct a pilot study (called e-WATCH) to investigate whether a successful/effective diet and physical activity tailored intervention in churches, consisting of tailored print messages and videotapes, can be effectively and efficiently disseminated to a different group of African Americans (colon cancer survivors) and using a different delivery method (electronic technology via the internet and world wide web). Secondary aims are to determine whether this intervention results in improvements in secondary outcomes, specifically self-efficacy and social support for improving health behaviors; and to use process evaluation measures to assess the feasibility, acceptability, and potential for wider dissemination of the e-WATCH program. Eligible participants (male and female African American colon cancer survivors, n=200), 40-79 years, diagnosed with either Stage I or II colon cancer who have successfully completed treatment for their disease and who are at least 6 months post-diagnosis will be randomly assigned to receive the culturally and individually tailored intervention or the control condition. They will complete a baseline survey online (querying on diet, physical activity, demographics, and psychosocial factors), receive the WATCH tailored feedback and information, and then six months after baseline complete a second survey assessing the same health behavior and psychosocial factors as at baseline. Control participants will receive a “delayed” intervention. Process and outcome evaluation measures collected pre- and post-intervention will assess exposure, cognitive processing, use of information, and acceptability. This pilot study would inform on the potential to use the internet to a deliver culturally and individually tailored health behavior intervention in African American colon cancer survivors, on whether such a program can be efficacious in this population, and could also contribute to the understanding of how successful health promotion interventions can be modified for use in different segments of the population and for alternative channels (methods) of delivery.
