  2. Abstract


The purpose of this study was to identify factors associated with colorectal cancer (CRC) screening test preference and examine the association between test preference and test completed.


Patients (n = 1224) were 50-70 years, at average CRC risk, and overdue for screening. Outcome variables were preference for fecal occult blood test (FOBT), colonoscopy (COL), sigmoidoscopy (SIG), or barium enema (BE), measured by telephone survey, and concordance between test preference and test completed assessed using medical records.


Thirty-five percent preferred FOBT, 41.1% COL, 12.7% SIG, and 5.7% BE. Preference for SIG or COL was associated with having a physician recommendation, greater screening readiness, test-specific self-efficacy, greater CRC worry, and perceived pros of screening. Preference for FOBT was associated with self-efficacy for doing FOBT. Participants who preferred COL were more likely to complete COL compared with those who preferred another test. Of those screened, only 50% received their preferred test. Those not receiving their preferred test most often received COL (52%).


Lack of concordance between patient preference and test completed suggests that patients' preferences are not well incorporated into screening discussions and test decisions, which could contribute to low screening uptake. Physicians should acknowledge patients' preferences when discussing test options and making recommendations, which may increase patients' receptivity to screening.

Recommendations from the 2010 National Institute of Health State of the Science Conference, “Enhancing Use and Quality of Colorectal Cancer Screening,” state there is a need to better understand the association between patients' preferences and the use of colorectal cancer (CRC) screening tests.1 This recommendation stems largely from the finding that national organizations endorse multiple options for the early detection and prevention of CRC.2, 3 The most commonly recommended modalities include the fecal occult blood test (FOBT), fecal immunochemical test (FIT), and colonoscopy (COL), but other tests, including flexible sigmoidoscopy (SIG), double-contrast barium enema (BE), and virtual colonoscopy (V-COL), are also considered options for screening. Although CRC screening rates have gradually increased over the past 10 years, they remain lower than those for other cancers.4, 5 Incorporating patients' preferences into physicians' screening recommendations may be a way to increase screening rates.

A number of studies have described variation in patients' preferences for CRC screening tests,6-15 and some have examined sociodemographic characteristics associated with preferences.8, 9, 11-16 Studies are consistent in reporting that stool blood testing and endoscopy (usually COL) are most often cited as the preferred options. With a few exceptions,7, 13 studies also have been consistent in reporting that sociodemographic characteristics including age, sex, race/ethnicity, and education are not associated with test preferences.9, 11, 12, 14-16

Associations between test preferences and test characteristics such as accuracy, convenience, and discomfort have also been examined.6-9, 11, 13-16 Concern about discomfort and convenience was consistently associated with a preference for FOBT,6-9, 11, 13, 14 whereas test accuracy was consistently associated with a preference for SIG or COL.7, 8, 11, 13-16 Screening-related factors such as physician recommendation and prior screening also have been examined in relation to test preferences, but results have been inconsistent.6, 8-13, 16

With the exception of Powell et al,12 very few studies have examined the associations between test preference and psychosocial factors such as perceived risk and self-efficacy, and most of the others examined only 1 or 2 constructs.6, 8, 9, 16 Only 3 studies have examined the relation between CRC screening test preference and the CRC test completed15, 17 or ordered by a physician.14 Wolf et al15 found that approximately 40% of their study sample did not receive the test they said they preferred, and Ruffin et al17 found only modest correlations between preferred test and test received. Although Schroy et al14 did not examine completion of screening, they found that 40% of the time physicians did not order the test their patient preferred.

Because psychosocial factors may influence CRC screening test preferences, which, in turn, may influence uptake of CRC screening, we examined the associations between a number of psychosocial variables and CRC test preference. We also assessed the concordance between baseline CRC screening test preference and the type of test completed.

  2. Abstract

Data from these analyses are from a 5-year randomized behavioral intervention trial designed to increase CRC screening.18 The trial was approved by the institutional review board at the University of Texas School of Public Health (UTSPH) and is registered on (NCT01084746).

Selection and Recruitment of Study Population

The study was conducted at Kelsey-Seybold Clinic, the largest multispecialty medical organization in Houston, Texas, with 21 locations. Eligible patients had received primary care at the clinic within the past year, were between 50 and 70 years old, never had CRC or polyps, had never been screened or were due for CRC screening according to American Cancer Society guidelines in effect at the time of the study,19 had not had a physical exam within the past year, did not have a prior diagnosis of Crohn's disease or ulcerative colitis, and were able to speak English.

Between January 2004 and February 2006, staff at the Kelsey Research Foundation mailed invitation letters to potentially eligible patients, who were identified monthly from the clinic's administrative database. A contact telephone number was included in the letter so that recipients could call and decline participation. Staff at the foundation telephoned patients who did not decline to introduce the study, confirm eligibility, and enroll them. Invitees were considered nonrespondents if they could not be reached after 6 calls that were made during different times of the day and on different days of the week. Contact information for interested patients was sent to the UTSPH research staff members, who conducted baseline telephone surveys. Of 1384 patients enrolled by foundation staff, 1224 (88%) completed a baseline survey; this group constituted the analysis sample for this study. A detailed description of the process of recruitment and enrollment, including a CONSORT diagram, was published elsewhere.18

Data Collection and Study Design

After administration of the baseline survey, participants were randomized to 1 of 3 study groups stratified by sex and past CRC screening status (ever screened vs overdue for screening). The tailored intervention group participated in an interactive, tailored computer program; the Web site group viewed general information about CRC screening from a publicly available Web site, Screen for Life, which is the national CRC awareness campaign from the Centers for Disease Control and Prevention; and the survey-only control group received no additional information about CRC screening. As part of the study, all participants completed a wellness visit and exam. At the 12-month follow-up, medical records were reviewed to collect CRC screening utilization data. Additional details on the intervention trial and outcome results, including factors associated with CRC screening adherence, were reported elsewhere.18


Outcome variables

The outcome used to examine correlates of CRC test preference was self-reported CRC screening test preference as measured on the baseline survey. Respondents were asked: “Now that you have heard descriptions of all 4 colon cancer screening tests, which one would you prefer to get, if you had a choice?” Responses included FOBT, SIG, COL, BE, and don't know/not sure.

The other outcome was concordance between test preference at baseline and type of CRC test received (FOBT, SIG, COL, BE) 12 months post intervention. Test received was ascertained from the clinic's medical record and administrative databases. For patients who completed more than 1 screening test during the study period, we counted the first test completed.


Because there is scant research on the psychosocial correlates of CRC test preferences, we selected variables from the baseline survey that have been shown in the literature to be associated with CRC screening.20, 21 Patient characteristics and the categories used for analytic purposes were: age (continuous), race (white, African American, Hispanic/other), sex (male/female), marital status (married/partnered, not married/divorced/widowed), employment status (employed, not employed/retired/disabled), education (high school graduate or less, some college, college graduate, postcollege education), and family history of CRC (yes, no). All participants in this study were insured; therefore, we did not include insurance status as a patient characteristic.18

Screening-related factors included prior CRC screening (yes or no), type of test received (FOBT, SIG, COL, BE), physician recommendation, stage of change or readiness to be screened, and preference for involvement in medical decision making. Prior screening was assessed with a standard set of measures.22 Patients were asked if they had ever received a physician's recommendation to be screened for CRC (yes or no) as well as whether they received a test-specific recommendation for FOBT, SIG, COL, or BE. Stage of readiness to get CRC screening was measured as precontemplation (not thinking about testing), contemplation, or preparation for action (committed to getting tested). Contemplation was measured using 3 questions: need to consider testing, think I should but am not quite ready, and think I will probably get tested. We used the 5-point Control Preferences Scale23 to characterize respondents' beliefs about how medical decisions should be made. We collapsed the scale into 3 categories reflecting a preference for a patient-based, shared, or physician-based decision.7, 24 Participants who did not respond to this question were coded as having an unknown preference.

Psychosocial factors included participants' test-specific self-efficacy, comparative perceived risk, worry about CRC, CRC knowledge, and perceived pros and cons of CRC screening. Test-specific self-efficacy was assessed with 4 items reflecting the degree to which respondents felt confident in completing each test (FOBT, SIG, COL, BE). The 4 response categories were dichotomized for analysis (very confident, confident, not very confident, not at all confident). Comparative perceived risk was measured with a single item from the 2003 Health Information and National Trends Survey (less likely, equally likely, or more likely to develop CRC compared with others my age). Worry about CRC was measured with a single item (never, rarely, sometimes, most of the time, all of the time). Knowledge was measured with 4 items (true/false). Perceived pros (α = 0.75, items = 8) and cons (α = 0.78, items = 10) for getting CRC screening were measured using validated multi-item scales with a 4-point response scale ranging from “not very important” to “very important.”25 We calculated mean scores for knowledge as well as perceived pros and cons of CRC screening.

Data Analysis

Univariable associations between baseline CRC test preference (FOBT, COL, SIG, or BE) and categorical independent variables were analyzed using chi-square contingency tables; continuous variables were analyzed using t tests and 1-way analysis of variance. Variables that were associated with test preference in univariable analyses at P < .10 were included in multivariable analyses to identify factors independently associated with preference stated at baseline. As recommended by Hosmer and Lemeshow, we used a less conservative P value (P < .10) to select variables for inclusion in the multivariable analyses in order to reduce the possibility we would exclude variables that could be important.26 We then performed a multinomial analysis using 3 outcome variables: FOBT, SIG, and COL. We used FOBT as the referent category to compare COL versus FOBT and SIG versus FOBT. We then used SIG as the referent category to compare COL versus SIG. Results were summarized with odds ratios and 95% confidence intervals. We excluded patients with a baseline preference for BE from the multinomial analysis because so few respondents indicated it as a test preference (6%). In the multivariable analyses, worry about CRC was collapsed into 2 categories (never/rarely and sometimes/most of the time/all of the time), and stage of readiness for CRC screening was analyzed as a continuous variable.

To evaluate concordance between baseline CRC test preference and type of test completed, we compared each patient's stated preference at baseline to his or her test completed by 12 months. This analysis included having an unknown preference at baseline and receiving no test by 12 months. Baseline preferences included FOBT, COL, SIG, BE, and unknown. Completion categories included FOBT, COL, SIG, and no test (only 2 patients had received BE by 12 months). Comparisons between stated preferences and test completion were done using chi-square analyses.

Description of the Sample

The mean age of study participants was 55.5 years; the sample was composed of patients who were predominantly African American or white, female, married, employed, and had at least a high school education (Table 1, columns 1 and 2). Only 7% reported a family history of CRC. Approximately half had previously been screened for CRC and were overdue, and approximately half reported that CRC screening had ever been recommended by a physician. Patients reported all CRC tests received; thus, the total number of specific tests completed or recommended exceeds the total reporting having ever been screened or recommended for screening (Table 1 footnote). About half stated that they preferred to make medical decisions themselves, whereas 40% preferred that medical decisions be shared; only 10% preferred that a physician make medical decisions. More than one third said they were committed to getting tested; fewer than 10% were not thinking about getting tested. Patients reported that they were “very confident” (had high self-efficacy) that they could complete FOBT compared with the other tests. More than half of the sample stated that they were equally likely to develop CRC compared with others their age. The majority reported that they rarely or never worried about CRC. Mean knowledge scores reflected some knowledge about CRC; mean scores were high for perceived pros and low for perceived cons of CRC screening.

Factors Associated with Baseline CRC Screening Preference: Univariable Analysis

Most patients stated a test preference: 34.7% indicated a preference for FOBT, 41.1% for COL, 12.7% for SIG, 5.7% for BE, and 5.8% did not report a preference. Factors statistically significantly associated at P<.10 with baseline test preference for COL, SIG, or FOBT in univariable analyses were family history, ever had CRC screening with SIG, physician recommendation for any CRC test, FOBT, and COL, preference for decision making, stage of readiness for CRC screening, test-specific self-efficacy for FOBT, COL or SIG, comparative perceived risk, worry, and perceived pros of CRC screening (Table 1, columns 3-6).

Factors Associated with Baseline CRC Screening Preference: Multivariable Analysis

Table 2 shows the multivariable logistic regression results for factors associated with preference for FOBT, COL, or SIG, always using the less invasive test as the referent. Because prior use of SIG was significantly associated with preference, we also included prior use of FOBT and COL in the multivariable models. Likewise, because physician recommendations for FOBT and COL were significant, we included recommendation for SIG. We did not include prior recommendation for any test (ie, “ever received a recommendation”) or for a nonspecific recommendation because of the high correlations with test-specific recommendations. The factors that remained statistically significantly associated in at least 1 of the multinomial regression models were prior use of CRC screening with SIG, prior test-specific physician recommendation, stage of readiness, test-specific self-efficacy, worry about CRC, and perceived pros of CRC screening.

Three factors were consistently and positively associated with a preference for 1 of the more invasive tests. Patients whose physicians recommended SIG or COL were more likely to prefer those tests to FOBT, as were patients who reported being more committed to screening and those who reported being more worried about CRC. Higher scores on the perceived pros of screening were associated with a preference for COL over FOBT and SIG.

Greater self-efficacy for completing a specific test was statistically significantly associated with a preference for that test. For example, those with high self-efficacy for FOBT were more likely to prefer FOBT to COL or SIG, whereas those with high self-efficacy for COL were more likely to prefer COL to FOBT or SIG. Interestingly, prior experience with SIG was associated with a preference for either of the other tests.

Baseline Test Preference and Test Utilization

Regardless of baseline test preference, most patients did not get screened.18 At the 12-month follow-up, more than 65% had no evidence in the medical record or administrative databases of receiving any CRC screening test; 9.7% had received FOBT, 22.3% had received COL, fewer than 2% had received SIG; and only 3 patients had received BE.

The pattern of association between baseline test preference and test completed was statistically significant (Fig. 1). These results were driven largely by the association between baseline preference for COL and receipt of COL. To explore this association further, we examined preference for COL compared with other tests in relation to screening at the 12-month follow-up. Participants who preferred COL at baseline were significantly more likely to complete COL by the 12-month follow-up compared with those who had a preference for any other test (χ2 = 9.98, P = .002). When we restricted the analysis to those who had been screened by 12 months (n = 448, or 34% of the sample), 51.3% (n = 215) received the test that they indicated they preferred at baseline. Of those who did not receive the test they preferred, the majority (51.9%) received COL.

  2. Abstract

Consistent with other studies, we found that most patients preferred COL or FOBT to the other CRC tests and that sociodemographic characteristics were not associated with test preferences.6-15 Collectively, these findings suggest that offering only the options of FOBT and COL would be acceptable to most patients. Moreover, the fairly even split in the percentage of patients who preferred those 2 tests supports the view that both tests should be offered to patients.

To our knowledge, ours is one of the few studies to examine psychosocial factors associated with test preference. Like Powell et al,12 we found an association between greater self-efficacy for screening with COL and a preference for that test. However, unlike Powell et al, we also found that greater self-efficacy for FOBT and SIG were associated with a preference for those tests. Powell et al also found that scoring high on the salience or importance of screening was associated with a preference for COL over other options, and we found that higher scores on the pros of screening were associated with a preference for COL. In our study, patients at a higher stage of readiness to get tested also preferred SIG or COL to other options. It may be that as patients learn about the benefits of screening and its importance in preventing CRC, they are more likely to commit to getting screened and to choose a test that, although invasive, can prevent CRC. Increasing support for COL by primary care physicians compared with other CRC screening tests may also contribute to patient preference for this option.27 In contrast, those least interested in getting screened were more likely to choose FOBT, a test that requires less planning and preparation, is more convenient to do, and is less invasive than SIG or COL.

Like 2 other studies,11, 12 we found an association between the test that a patient said the physician recommended and preference for that test. However, 1 study8 found that one third of the patients in the sample said they would adhere to their choice even if their physician recommended an alternative test. Our finding that only 10% of the patients in our sample favored having a physician make their medical decisions supports the view that although patients may value the opinions of their physicians, they want to have a voice in making medical decisions. These findings underscore the need for physicians to be aware of and consider patients' preferences when making recommendations. Our findings also support educating patients about the importance of advocating for their own preferences in visits with their physicians.

With the exception of SIG, we found no association and no consistent pattern in the odds ratios between prior screening with a specific test and preference for future screening with that test. In fact, counter to what might be expected, prior experience with SIG was associated with a preference for either of the other tests, suggesting that having SIG did not reinforce a commitment to future screening with SIG. Likewise, findings from other studies also have been inconsistent with respect to the association between prior screening and preference, with some studies finding a positive association,8-10, 16 some finding no association,6, 11, 13 and some finding different patterns depending on the test.7, 12 The lack of association between prior screening with COL or FOBT and a preference for those tests together with the positive association between physician recommendation and a preference for the recommended test suggests that prior screeners may be open to considering other test options. However, our finding that patients preferred the test that they were more confident they could complete suggests that physicians need to take patients' perceived confidence into consideration when they make a test recommendation.

Although consistent with other studies,14, 15, 17 our potentially most concerning finding was the lack of association between patients' stated test preference at baseline and the type of test they received (if any). This discrepancy could contribute to the overall low uptake of screening we observed, and future studies should investigate whether patients who do not feel that their test preferences are supported by their physicians are less likely to be adherent to CRC screening recommendations and guidelines. Recent studies have found that the extent of informed decision making for CRC screening during primary care visits is minimal.28, 29 Recent studies, including 1 conducted with a subsample of participants in this intervention trial, also have documented that primary care physicians tend to recommend COL above other screening tests regardless of a patient's expressed preference.27, 29, 30 If COL continues to be the most commonly recommended CRC screening test in primary care,27, 29, 30 educational programs that emphasize the benefits of COL may increase patients' receptivity to it, particularly if they are supported by a discussion with the provider and by systems that facilitate scheduling and completing the test.

Our findings need to be interpreted in the context of several limitations. The study setting was a large multispecialty group practice where patients have relatively equal access to all CRC tests; therefore, our results may not generalize to settings without access to all test options. In addition, the study design used to assess associations between preference and psychosocial and other factors was cross-sectional; therefore, inferences about the direction of influence cannot be made. Finally, test preference was only assessed at baseline, and it is possible that it changed after patients met with their physicians. If this were the case, it could explain why patients who preferred COL were more likely to be screened compared with those who preferred other tests and why patients who preferred FOBT received COL.

  2. Abstract

Patients at a higher stage of readiness for CRC screening, who reported more pros of screening, and who expressed more worry about CRC preferred one of the more invasive tests. Although, in general, patients preferred the test their physicians recommended, lack of concordance between patient preference and test completed suggests that patients' preferences are not well incorporated into screening discussions and test decisions. Ensuring that patients understand the benefits of screening and that they receive information about what each test entails may increase their self-efficacy and make it more likely that they will complete the test they choose.

Practice Implications

Primary care physicians need to be aware that patients' preferences for CRC screening tests differ. Assessing and acknowledging these preferences when making CRC screening recommendations could positively affect patient adherence. In addition, educating patients about the benefits of screening and providing support for completing the test they choose may make patients more receptive to CRC screening.
