This clinical trial studies how well PreView, preventive video education, works in increasing rates of breast, cervical and colorectal cancer screening, improving participants' stage of change with respect to age appropriate cancer screening and increasing patient-provider discussions about prostate cancer screening.



  1. To determine the extent to which PreView increases the likelihood that primary care patient participants will receive mammograms, pap tests, colon cancer tests or prostate specific antigen (PSA) testing discussions with primary care physicians compared with participants who receive usual care.

II. To determine the extent that PreView increases participants' readiness to be screened for breast cancer, cervical cancer or colorectal cancer (CRC) compared with usual care.

III. To determine the extent that PreView increases the likelihood that PSA testing will be discussed in primary care physician visits compared with usual care.

OUTLINE: Patients are randomized into 1 of 2 groups.

GROUP I: Patients complete PreView, the Video Doctor plus Provider Alert, over 45 minutes on an iPad in the waiting room before a doctor visit.

GROUP II: Patients watch a video about healthy lifestyles including information about exercise and healthy eating over 45 minutes on an iPad in the waiting room before a doctor visit.
