Of 2,641 eligible patients aged 18 years and older who were approached, 1,754 completed surveys, for a 66.4% response rate. A total of 240 Spanish language questionnaires were completed, and 60 were completed as a whole or in part as an interview. In those practices with Spanish-speaking patients, data collectors were fluent in Spanish. Of the 1,754 respondents, the 467 women and 257 men who were aged 50 years and older were analyzed. Seven primary care practices were represented in this sample, with 16 to 180 participants from each practice.
The mean age of respondents was 62.2 years (range 50 to 95 years), and 64.5% of the respondents were female (sex not reported by one respondent) (). Black (44.1%) and white (45.7%) participants were equally represented, with other races accounting for 10.2% of the total. Although participants were asked to select one or more racial group from a list, every participant marked only one race.
Characteristics of the Participants (n=725)
Distribution of Survey Responses
Almost 40% of the participants reported feeling unsure about what to do about cancer screening tests (16.1% strongly agree, 22.6% agree); a similar number disagreed with this statement, and 16.3% neither agreed nor disagreed (). Most participants reported they knew the benefits of cancer screening (43.2% strongly agree, 33.2% agree), and more than half stated they knew the risks (27.3% strongly agree, 29.8% agree). Nearly 70% of the participants reported they had made informed choices about cancer screening. Most said their regular doctor asks for patient input regarding cancer screening tests (39.9% definitely yes, 40.7% yes). However, fewer patients reported that their doctor gives them some control over these tests (22.0% definitely yes, 28.7% yes, 19.4% definitely no). After adjusting for practice site, no statistically significant differences were seen in the trend of odds for responses from women compared to men.
Survey Responses in Women (n=467 total) and Men (n=257 total) Aged 50 and Older
Differences by Sex and Race
In the multivariable analysis of survey responses ( and ), men had greater adjusted odds than women of reporting they did not know the benefits of cancer screening (1.46, 95% CI=1.08, 1.99). Sex was not significantly associated with a difference in any other response item.

Table 3 B
Patient Characteristics Associated With Survey Responses in Multivariable Analyses, Adjusted Odds Ratios (n=592 to 656)
Black respondents had greater adjusted odds than white respondents of reporting they did not know the benefits (1.70, 95% CI=1.23, 2.36) or risks (1.38, 95% CI=1.00, 1.90) of cancer screening tests, had not made informed choices about these tests (1.50, 95% CI=1.09, 2.07), and that their doctor did not give them some control over their cancer screening tests (1.57, 95% CI=1.12, 2.20). Non-black/non-white women reported responses similar to black women regarding the risks of, and whether their doctor would give them some control over, cancer screening tests.
Differences by Education and Self-rated Health
Respondents with more education (associate degree and above versus less than high school education) reported greater adjusted odds of not feeling unsure about their decisions about cancer screening tests (2.05, 95% CI=1.32, 3.17) and lower adjusted odds of feeling they did not know the benefits of cancer screening (0.41, 95% CI=0.26, 0.64) (). No statistically significant associations were found between self-rated health and the outcomes in the adjusted analysis.
