Process evaluation is essential to understanding and interpreting the results of randomized trials testing the effects of behavioral interventions. A process evaluation was conducted as part of a comparative effectiveness trial testing a mailed, tailored interactive digital video disc (DVD) with and without telephone-based patient navigation (PN) to promote breast, cervical and colorectal cancer screening among rural women who were not up-to-date (UTD) for at least one screening test. Data on receipt, uptake, and satisfaction with the interventions were collected via telephone interviews from 542 participants who received the tailored interactive DVD (n = 266) or the DVD plus telephone-based PN (n = 276). All participants reported receiving the DVD and 93.0% viewed it. The most viewed sections of the DVD were about colorectal, followed by breast, then cervical cancer screening. Most participants agreed the DVD was easy to understand, helpful, provided trustworthy information, and gave information needed to make a decision about screening. Most women in the DVD+PN group, 98.2% (n = 268), reported talking with the navigator. The most frequently discussed cancer screenings were colorectal (86.8%) and breast (71.3%); 57.5% discussed cervical cancer screening. The average combined length of PN encounters was 22.2 minutes with 21.7 additional minutes spent on coordinating activities. Barriers were similar across screening tests with the common ones related to the provider/health care system, lack of knowledge, forgetfulness/too much bother, and personal issues. This evaluation provided information about the implementation and delivery of behavioral interventions as well as challenges encountered that may impact trial results.

Two interventions to promote cervical, breast, and colorectal cancer screening among rural women who were not up-to-date (UTD) for at least one screening test were evaluated by rural women who received them as part of the randomized trial. Participants who received the tailored interactive digital video disc (DVD; n = 266) or the DVD plus telephone-based patient navigation (PN; n = 276) were interviewed by phone about their engagement and satisfaction with the interventions. All participants reported receiving the DVD and 93.0% viewed it. Most agreed the DVD was easy to understand, helpful, provided trustworthy information, and gave information needed to get screened. Almost all women in the DVD+PN group, 98.2% (n = 268) talked with the navigator. The most common cancer screenings discussed with navigators were colorectal (86.8%), followed by breast (71.3%) and cervical (57.5%). The average length of encounters with the navigators was 22.2 minutes; navigators spent 21.7 additional minutes on coordinating activities. Barriers discussed were similar across screening tests. The most common were related to the healthcare provider/system, lack of knowledge, forgetfulness/too much bother, and personal issues. This study provided important information about receipt, uptake, and satisfaction with two behavioral interventions, along with challenges encountered that may impact results.
