Relationships among breast cancer concern, risk perceptions, and interest in genetic testing for breast cancer susceptibility among African-American women with and without a family history of breast cancer
Im. Lipkus et al., Relationships among breast cancer concern, risk perceptions, and interest in genetic testing for breast cancer susceptibility among African-American women with and without a family history of breast cancer, CANC EPID B, 8(6), 1999, pp. 533-539
There has been very little research exploring the relationships among perce
ptions of, and concern about, getting breast cancer and interest in genetic
testing for breast cancer among African-American women with and without a
family history of breast cancer. This study explored these issues among 130
and 136 African-American women with and without a family history of breast
cancer, respectively. Women with a family history reported having greater
perceived breast cancer risks and concerns than women without a family hist
ory of breast cancer. Knowledge of breast cancer risk factors was very poor
and correlated weakly with perceptions of risk and concern. In attribution
al analyses, acknowledging one's family history status was the strongest pr
edictor of perceived risk only among women with a family history. Women wit
h a family history of breast cancer expressed greater interest in genetic t
esting for breast cancer susceptibility than women without a family history
, although interest in testing was high overall. Increasing perceptions of
breast cancer risks and concerns were related to a greater interest in gene
tic testing, and this relationship was not moderated by family history stat
us. Attributions of risk and knowledge of breast cancer risk factors genera
lly were not related to interest in testing. Overall, these results suggest
that: (a) African-American women with a family history are more concerned
about and do recognize their greater risk of breast cancer; (b) knowledge o
f risk factors and attributions of risk are not directly related to interes
t in genetic testing; and (c) concerns, rather than beliefs about one's ris
k, are more powerfully related to interest in genetic testing, independent
of family history status.
