我们评估了关于乳腺癌易感性基因检测的心理社会后果信息对人们对基因检测的兴趣和信念的影响，以及这些影响是否会因癌症担忧程度或感知到的癌症风险程度而变化。在一项实验研究中，女性（N = 180）被随机分配阅读四种信息中的一种，这些信息包括标准信息以及关于心理社会优势、潜在劣势、优势和劣势的信息，或者没有额外的信息。仅获得标准信息的妇女比获得额外的优势、劣势或优势和劣势信息的妇女更有兴趣进行基因检测。对癌症的担忧（而不是感知到的风险）预示着更大的兴趣和对检测好处的更积极的信念。认为考试会导致情绪困扰的信念与担忧呈正相关，与风险认知负相关。
We assessed the impact of information about psychosocial consequences of genetic testing for breast cancer susceptibility on interest in and beliefs about genetic testing, and whether these effects vary by levels of either cancer worry or perceived cancer risk. Women (N = 180) in an experimental study were randomly assigned to read one of four messages consisting of standard information along with information about either psychosocial advantages, potential disadvantages, both advantages and disadvantages, or no additional information. Women receiving only standard information reported higher interest in obtaining genetic testing than did women who received additional information about advantages, disadvantages, or both advantages and disadvantages. Cancer worry (but not perceived risk) predicted greater interest and more favorable beliefs about the benefits of testing. Beliefs that testing causes emotional distress were positively associated with worry and negatively associated with risk perceptions.
