“…Weinstein (1984) concluded that although absolute and comparative risk estimates were moderately intercorrelated and equally associated with objective risk factors, each assessed different aspects of people's risk-related cognitions. Similarly, Rowe et al (2005) found that although absolute and comparative measures of breast cancer risk were moderately intercorrelated, only the comparative measure was associated with health locus of control. We reasoned, therefore, that each of these definitional approaches reflects a necessary yet somewhat independent component of how people think about disease risk.…”

As is true for many behavioral theory constructs, no consensus exists on how best to measure perceived risk; therefore, it is unclear whether different measures of disease risk perception are conceptually equivalent and whether such measures are equally appropriate for people with different objective disease risk. To investigate these issues, we used four commonly utilized risk perception items (measuring beliefs about personal risk, others' risk, disease prevalence, and mortality) to assess susceptibility to cardiovascular disease, breast cancer, and lung cancer among 454 younger (ages 18-25) and 169 middle-aged (40-64) women. We examined age- and ethnicity-related differences in participants' responses to the items. We also used structural equation modeling to test whether these items reflect a multidimensional, disease-specific latent construct of risk perception; and to test whether consistency exists in participants' disease-specific risk perceptions. Despite differences in responses to individual items, hypothesized models of perceived risk fit both age groups, suggesting that risk perception can be conceptualized in younger and middle-aged women as a multidimensional construct that is specific to disease yet reflective of global risk-related beliefs.

“…Similar types of items have been used in prior research to evaluate certainty about one's breast cancer risk. 24 Responses to these items were re-coded into dichotomous variables based on the distribution of responses (e.g., at risk vs. not at risk and more certain vs. less certain). We used the breast cancer worry scale to evaluate cancer-specific worry.…”

Purpose: This study evaluated rates of BRCA1 and BRCA2 (BRCA1/2) test result acceptance among African American women and identified determinants of test result acceptance. Methods: Acceptance of BRCA1/2 test results was evaluated among 157 African American women at high and moderate risk for having a BRCA1/2 mutation who were offered genetic testing as part of a clinical genetic counseling research program. Results:Twenty-two percent of women received BRCA1/2 test results. Test result acceptance differed between women with Ն10% prior probability of having a BRCA1/2 mutation (34%) and those who had a 5% prior probability (8%). Among women with Ն10% prior probability, test result acceptors were most likely to be married (OR ϭ 5.29, 95% CI ϭ Recently, epidemiological studies have shown that the prevalence of BRCA1 and BRCA2 (BRCA1/2) mutations range from 16 -28% among African American women who have a personal and family history of breast and/or ovarian cancer suggestive of hereditary disease. [1][2][3][4] If found to carry a BRCA1/2 mutation, women have an estimated 60 -80% lifetime risk of developing breast cancer and a 10 -45% lifetime risk of developing ovarian cancer. [5][6][7] Because of the excess rates of breast cancer mortality among African American women, 8,9 participation in genetic counseling and testing may be beneficial to women at increased risk for hereditary cancer to increase knowledge about cancer risks and options for risk reduction. Efforts are now being made to enhance access to genetic counseling and testing for BRCA1/2 mutations among African American women at increased risk for hereditary disease. Recent research has shown that as many as 50% of African American women may participate in genetic counseling for breast cancer susceptibility, 10 but little is known about rates of acceptance of BRCA1/2 test results or determinants of test result acceptance.To address this gap in our knowledge, we evaluated rates of BRCA1/2 test result acceptance among African American women at increased risk for hereditary breast and ovarian cancer and identified sociodemographic, clinical, and psychological barriers and facilitators to receiving genetic test results. Because prior studies have shown that cancer-specific worry may influence decisions about participating in genetic counseling among African American women 11 we were interested in exploring the relationship between BRCA1/2 test result acceptance and cancer-specific worry. Other reports have shown that many African American women would want to have genetic testing to be reassured about their cancer risk 12 ; however, it is possible that women who are uncertain about their risk of developing cancer may be most likely to receive test results to better define their risk of disease. Thus, we were also interested in determining whether certainty about one's risk of developing breast cancer is associated with genetic test acceptance. Since previous research has shown that responses to education about hereditary breast cancer and genetic testing may diffe...

“…Even when accurate medical information was available, health beliefs were still based on family legacies! Overall, compared to women with no familial risk, those with a risky family profile view breast cancer as a more salient threat and see fewer hindrances to and more benefits in early detection measures 12,19,23,[26][27][28][29] (but see another study 25 ). This raises the question as to whether interactions between health beliefs are overshadowed by family history.…”
