Abstract
BACKGROUND: Colorectal cancer (CRC) screening decision aids can inform patients about CRC screening benefits, costs, and procedures. Patients who receive the decision aid report wanting to share the information with their families and friends. We evaluated a CRC screening decision aid on Hispanic patients' communication to their alters and whether patient-alter communication leads to alters' CRC screening intention. METHODS: We conducted a one-arm pre/post study of Hispanic patients and their alters; patients (n = 42) and their alters (n = 19) were recruited from a clinic site in Yakima County, Washington State. Patients viewed a CRC screening decision aid at the clinic site. Survey data from patients and alters were collected via telephone including patients' communication with their alters about CRC screening after viewing the decision aid and alters' intention to be screened for CRC after talking to the patient. RESULTS: Most participants reported sharing CRC information with their alters after viewing the decision aid, and most alters confirmed they had received CRC information from participants (68%). The decision aid was associated with participants' own intention to undergo CRC screening and with alters' intention to be screened for CRC using a fecal occult blood test (p = 0.014) and sigmoidoscopy (p = 0.011). CONCLUSIONS: Patient decision aids have the potential to increase CRC screening behavior beyond the decision aid recipients to their social network.
