Bold numerals denote statistically significant values with p<0.05.
Concern about breast cancer was dichotomized into “very concerned” about getting breast cancer vs. “somewhat/a little/not at all” concerned.
All models controlled for race/ethnicity, age, marital status, level of education, language of interview, insurance status, study site, number of comorbid conditions, and correct perception of risk. Multivariate models only controlled for any blood relative with breast cancer for average risk women, as the Gail, BCSC, and RST models all incorporate family history of breast cancer.
This variable was only examined in average risk women as the Gail, BCSC, and RST models all incorporate family history of breast cancer.
Average risk women who responded that their lifetime risk was the same or lower than other women of the same age were considered to have correct perception of their breast cancer risk, as were high risk women who responded that their lifetime risk was higher than other women of the same age.
