We used the Health Belief Model (HBM) to explore factors associated with readiness for genetic counseling among breast cancer survivors. Breast cancer survivors meeting NCCN genetic counseling referral criteria completed questionnaires capturing demographic and clinical information and factors guided by the HBM, including health beliefs, psychosocial variables, and cues to action. Using logistic regression, we examined whether the above variables differed based on readiness group (pre-contemplators, who did not plan to make a genetic counseling appointment, and contemplators, who planned to make a genetic counseling appointment in the next 1-6 months). Of 111 participants, 57% were pre-contemplators and 43% were contemplators. Higher cancer worry was associated with increased odds of being a contemplator (OR = 2.99; 95% CI = 1.37-6.54) and higher perceived barriers to genetic counseling were associated with decreased odds of being a contemplator (OR = 0.31; 95% CI = 0.11-0.85). Those who reported a family member encouraged them to get tested were more likely to be contemplators (OR = 3.57; 95% CI = 1.19-10.70). Our results suggest key factors for predicting genetic counseling readiness include cancer worry, perceived barriers, and family influence. There is need for increased genetic counseling awareness. Better understanding of factors related to survivors' decisions about counseling can inform tailored interventions to improve uptake and ultimately reduce cancer recurrence risk.
我们使用健康信念模型(HBM)来探讨与乳腺癌幸存者进行遗传咨询准备情况相关的因素。符合 NCCN 遗传咨询推荐标准的乳腺癌幸存者完成了调查问卷,其中包括人口统计学和临床信息以及 HBM 指导下的因素,包括健康信念、心理社会变量和行动线索。我们使用逻辑回归检查了上述变量是否根据准备情况分组(未考虑者,不计划预约遗传咨询,和考虑者,计划在接下来的 1-6 个月内预约遗传咨询)存在差异。在 111 名参与者中,57%为未考虑者,43%为考虑者。更高的癌症担忧与成为考虑者的几率增加相关(OR=2.99;95%CI=1.37-6.54),而更高的遗传咨询障碍与成为考虑者的几率降低相关(OR=0.31;95%CI=0.11-0.85)。那些报告有家庭成员鼓励他们进行测试的人更有可能成为考虑者(OR=3.57;95%CI=1.19-10.70)。我们的结果表明,预测遗传咨询准备情况的关键因素包括癌症担忧、感知障碍和家庭影响。需要提高遗传咨询意识。更好地了解与幸存者关于咨询的决定相关的因素可以为制定针对性的干预措施提供信息,以提高接受率,最终降低癌症复发风险。
