To assess the impact of numeracy and health literacy on client's ability to learn information orally communicated during a BRCA 1/2 genetic counseling session.
Fifty-nine videotaped simulated genetic counseling sessions were shown to 246 analogue clients (AC) recruited to imagine themselves as the client in the genetic counseling session. AC numeracy, genetic literacy, state and trait anxiety, and decisional conflict were assessed. The primary outcome was AC learning about BRCA 1/2.
Health literacy and numeracy were moderately correlated, and each independently predicted learning. Higher numeracy was associated with higher knowledge scores only among ACs with adequate literacy. Decisional conflict was not related to literacy, numeracy, or knowledge acquisition. It was, however, inversely related to state anxiety so that the higher post-session state anxiety, the lower the AC's decisional conflict.
Numeracy and health literacy are associated with learning of orally communicated information during genetic counseling. It appears that numeracy can facilitate learning for literate subjects; it does not, however, make any difference in learning ability of clients with significant literacy deficits.
Numeracy plays an important role in client's ability to learn information communicated during medical sessions, especially among clients who are otherwise regarded as literate.
评估计算能力和健康素养对客户在接受 BRCA1/2 基因咨询期间通过口头交流获取信息能力的影响。
246 名模拟客户（AC）观看了 59 个录像模拟基因咨询会议，这些模拟客户被要求想象自己是基因咨询会议中的客户。评估了 AC 的计算能力、遗传素养、状态焦虑和特质焦虑以及决策冲突。主要结果是 AC 对 BRCA1/2 的了解。
健康素养和计算能力呈中度相关，并且各自独立预测学习。较高的计算能力仅与具有足够素养的 AC 较高的知识得分相关。决策冲突与素养、计算能力或知识获取无关。然而，它与状态焦虑呈负相关，因此，咨询后状态焦虑越高，AC 的决策冲突越低。
计算能力和健康素养与基因咨询期间口头交流信息的学习相关。计算能力似乎可以促进有素养的受试者的学习；然而，对于有明显素养缺陷的客户，学习能力没有任何区别。
计算能力在客户在医疗过程中获取信息的能力方面起着重要作用，特别是对于那些被认为有文化素养的客户。
