Abstract

Background. Although colorectal cancer is the third most common cancer in women, little is known about predictors of adherence to screening.

Methods. A randomly selected sample of 202 predominantly low-income and African-American women were interviewed. Knowledge of, attitudes and beliefs about, and practices related to flexible sigmoidoscopy (FS) screening were assessed.

Results. The majority of participants were in the precontemplation stage of adoption (56%). There were significant differences by stage of adoption for FS beliefs, FS barriers, risk of developing colorectal cancer, worry about getting colorectal cancer, and physician recommendation to get a FS. Predictors of adherence to FS guidelines were perceiving fewer barriers to getting a FS and having a physician recommend a FS.

Conclusion. Seventy-two percent of the women in this study were nonadherent to FS screening guidelines. Psychosocial factors play an important role in screening for colorectal cancer. Ways of reducing barriers and increasing physician recommendations should be explored.

      The most frequently examined psychosocial factors were perceived barriers (n = 7) (Tang et al., 2001; Power et al., 2008; Sutton et al., 2000; Wardle et al., 2005; Whitaker et al., 2011; Brenes and Paskett, 2000; Rawl et al., 2004), perceived benefits (n = 7) (Power et al., 2008; Sutton et al., 2000; Wardle et al., 2005; Whitaker et al., 2011; Janz et al., 2003; Lewis and Jensen, 1995; Senore et al., 2010), perceived risk (n = 9) (Tang et al., 2001; Power et al., 2008; Sutton et al., 2000; Wardle et al., 2005; Ko et al., 2005; Lewis and Jensen, 1995; van Dam et al., 2013; Kremers et al., 2000; Senore et al., 2010; Brenes and Paskett, 2000), attitudes towards medical tests (n = 3) (Power et al., 2008; Sutton et al., 2000; Senore et al., 2010), anticipated regret (n = 2) (Power et al., 2008; van Dam et al., 2013) and receipt of a physician recommendation to have the test (n = 2) (Lawsin et al., 2007; Taylor et al., 2003). Those most frequently positively associated with FS screening use included lower perceived barriers (n = 7/7, 100%) (Tang et al., 2001; Power et al., 2008; Sutton et al., 2000; Wardle et al., 2005; Whitaker et al., 2011; Brenes and Paskett, 2000; Rawl et al., 2004), higher perceived benefits (n = 5/7; 71.4%) (Power et al., 2008; Sutton et al., 2000; Wardle et al., 2005; Whitaker et al., 2011; Lewis and Jensen, 1995), higher perceived risk (n = 2/9; 22.2%) (Janz et al., 2003; Kremers et al., 2000), receipt of a recommendation from the clinician to have the test (n = 2/4; 50%) (Lawsin et al., 2007; Taylor et al., 2003) and positive attitudes towards medical tests (n = 2/3; 66.7%) (Power et al., 2008; Sutton et al., 2000). Other psychosocial factors found to be positively associated with FS screening use at least once, included: lower perceived test pain (n = 1/1; 100%) (Lewis and Jensen, 1995), higher consideration of future consequences (n = 1/1; 100%) (Whitaker et al., 2011), higher acculturation (n = 1/2; 50%) (Tang et al., 2001), higher knowledge of FS screening (n = 1/1; 100%) (van Dam et al., 2013), receiving a recommendation to have the test from a family member (n = 1/1; 100%) (Walsh et al., 2004), having previously thought about getting the test done (n = 1/1; 100%) (Walsh et al., 2004) and positive attitudes towards CRC screening tests (n = 1/1; 100%) (van Dam et al., 2013).

      This assumption is indirectly supported by a number of studies that have demonstrated that PCP-conducted screenings result in higher compliance as a result of PCPs' ability to better educate their patients, to have already established trust with the patient, and to leverage electronic health records for timely prompting (Levy et al., 2006; Lewis et al., 2000; O'Malley et al., 2004; Rogge et al., 1994; Stone et al., 2002; Wilkins et al., 2009). Lack of physician recommendation for CRC screening has been cited as a major contributor to low CRC screening compliance (Brenes and Paskett, 2000; Lewis and Jensen, 1996). We contend that PCPs who are able to perform FS or colonoscopy would be generally more aware of recommended screening protocols and would be more likely to recommend CRC screening to their patients.

      Alternatively, it is also possibly due to the heterogeneity in both conceptual and operational definitions of the construct in these studies. Out of the seven studies, three studies used one single item to assess worry of getting CRC on a 3-point or 4-point Likert scale (Brenes and Paskett, 2000; Costanza et al., 2005; Sutton et al., 2000), one study use nine items to assess nine different aspects of fear, one item for each aspect of fear being measured (Bynum et al., 2012), one study used four items to assess fear of CRC in four different situations (Kremers et al., 2000), while the remaining two did not provide information on how the fear construct was operationalized (Kelly and Shank, 1992; Myers et al., 2007). Apparently, the present instruments for measuring fear of colorectal cancer may not be adequate when assessing the construct.
