There has been very little research exploring the relationships among perceptions 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 history of breast cancer. Knowledge of breast cancer risk factors was very poor and correlated weakly with perceptions of risk and concern. In attributional analyses, acknowledging one's family history status was the strongest predictor of perceived risk only among women with a family history. Women with a family history of breast cancer expressed greater interest in genetic testing 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 genetic testing, and this relationship was not moderated by family history status. Attributions of risk and knowledge of breast cancer risk factors generally 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 of risk factors and attributions of risk are not directly related to interest in genetic testing; and (c) concerns, rather than beliefs about one's risk, are more powerfully related to interest in genetic testing, independent of family history status.
针对有和没有乳腺癌家族病史的非裔美国女性,探究她们对患乳腺癌的认知、担忧与乳腺癌基因检测兴趣之间关系的研究非常少。本研究分别对130名有乳腺癌家族病史和136名无乳腺癌家族病史的非裔美国女性的这些问题进行了探究。有家族病史的女性报告称,她们感知到的乳腺癌风险和担忧程度高于没有乳腺癌家族病史的女性。对乳腺癌风险因素的了解非常匮乏,且与风险感知和担忧的关联较弱。在归因分析中,只有在有家族病史的女性中,承认自己的家族病史状况才是感知风险的最强预测因素。有乳腺癌家族病史的女性比没有家族病史的女性对乳腺癌易感性基因检测表现出更大的兴趣,不过总体而言检测兴趣都很高。对乳腺癌风险和担忧的感知增加与对基因检测的更大兴趣相关,且这种关系不受家族病史状况的调节。风险归因和乳腺癌风险因素的知识通常与检测兴趣无关。总体而言,这些结果表明:(a) 有家族病史的非裔美国女性更担心且确实认识到自己患乳腺癌的风险更高;(b) 风险因素的知识和风险归因与基因检测兴趣没有直接关系;(c) 担忧而非对自身风险的信念,与基因检测兴趣的关联更为密切,且不受家族病史状况的影响。
