The goal of this study is to test a program to improve CRC screening among male and female patients over the age of 50 in 10 primary care clinics. This study will use physician surveys, focus groups and a community advisory board to finalize the content of the interventions. Five theoretical models form the theoretical framework of the study - the health belief model, social networking, minority health communications model, PEN III, and the transtheoretical model. The interventions will be directed at the clinic and patient levels, and will be tested in a randomized design. Five clinics will receive the clinic plus patient-directed interventions and 5 clinics will be randomized to usual care. The clinic intervention will consist of provider, system and waiting room activities. The individual-directed intervention will include three stepped stages for patients who have not yet been screened: (1) a tailored physician letter, easy-to-read educational materials about CRC and an FOBT information sheet and card; (2) follow-up telephone barriers counseling for patients who do not complete CRC screening after receiving the letter; and (3) in person home visits by lay health advisors (LHA) for those who do not complete CRC screening after receiving the first two interventions. Research staff will conduct a process evaluation of the interventions to identify problems in implementing them and determine the extent to which each of the components is successfully carried out. They will also examine how components of the intervention relate to the theoretical frameworks used to motivate CRC screening completion. If successful, this program can easily be adapted for use by primary care practices and clinics to improve CRC screening.
