To assess a genetic counseling intervention measuring the distress, cancer risk perception, anxiety, worry and level of knowledge in people with familial history of breast cancer.
One group pre- and post-test design. A total of 212 individuals completed a baseline questionnaire, 88.6% completed a second questionnaire one month later and 75.4% six months later.
Counseling intervention significantly increased the knowledge level of the individuals who received genetic education and significantly decreased the cancer worry levels. Persons with low perception of their cancer risk also had low worry levels. There were no significant changes over time in cancer risk perception or in quality of life.
Counseling in a high risk population seems to decrease cancer worry and to increase cancer knowledge thus enabling a counselee to take well-informed decisions. Furthermore, according to our results, such interventions do not increase anxiety and do not modify the quality of life, but do not adjust their cancer risk perception.
Providing individuals at increased risk of breast cancer genetic services seem to enhance their understanding of breast cancer without causing adverse psychological effects or changes in their quality of life, and it could improve their preventive behaviours.
评估一项遗传咨询干预措施,以衡量有乳腺癌家族史的人群的痛苦、癌症风险认知、焦虑、担忧和知识水平。
采用单组前后测设计。共有 212 名个体完成了基线问卷,88.6%的个体在一个月后完成了第二次问卷,75.4%的个体在六个月后完成了第二次问卷。
咨询干预显著提高了接受遗传教育的个体的知识水平,显著降低了癌症担忧水平。低癌症风险认知的人也有较低的担忧水平。癌症风险认知或生活质量在时间上没有显著变化。
在高危人群中进行咨询似乎可以降低癌症担忧,增加癌症知识,从而使咨询对象能够做出明智的决定。此外,根据我们的结果,这种干预措施不会增加焦虑,也不会改变生活质量,但不会调整他们的癌症风险认知。
为有乳腺癌遗传风险的个体提供服务似乎可以增强他们对乳腺癌的理解,而不会产生不良的心理影响或改变他们的生活质量,并且可以改善他们的预防行为。
