Thesis (D.S.N.)--The University of Alabama at Birmingham, 2001.

In the United States breast cancer is the second leading cause of death from cancer in women and the most frequently diagnosed cancer in women. Advances in genetic science have lead to the discovery of specific genetic mutations that lead to early onset breast cancer and are thought to account for 5% to 10% of all breast cancers. Guided by the Health Belief Model, the descriptive correlational study examined predictive relationships among perceived risk of having an altered breast gene, perceived susceptibility to breast cancer, perceived seriousness of breast cancer, awareness of genetic testing, perceived benefits and limitations of genetic testing, knowledge about inherited breast cancer and breast cancer gene 1 (BRCA1) and breast cancer gene 2 (BRCA2), family history of breast and ovarian cancer, risk factors for breast cancer, health motivation, age, race, and intent to obtain genetic testing. A multilevel purposive sample of 270 women was used. A composite questionnaire using the Health Belief Subscales (Champion, 1993, 1995), National Center for Human Genome Research Cancer Studies Consortium Scales (Lerman, Daly, Masny, & Balshem, 1994; Lerman, Kash, & Stefanik, 1994; Lerman, Seay, Balshem, & Audrian, 1995), and the Myriad Family History Questionnaire (Myriad Genetics, 1999) were used for data collection. Multiple regression analysis revealed that perceived susceptibility to breast cancer, intent to obtain genetic testing, and the number of first degree relatives with ovarian cancer were predictors of perceived risk of having an altered breast gene, explaining 29% of the model. There were multiple significant correlations among other health belief variables including awareness of genetic testing with knowledge and age (r = .41 and r = .21, respectively, both at p < .01), perceived susceptibility to breast cancer with perceived seriousness of breast cancer, perceived barriers to genetic testing, first degree relatives with breast cancer, first degree relatives with breast cancer less than age 50 years old (r = .29; r = .25, r = .28, r = .21 respectively, all at p < .01), and benefits and barriers to genetic testing (r = .46, p < .01).
