目的 确认使用语音触摸屏技术的健康素养评估 (Health LiTT) 测量的健康素养分数与认知能力和教育之间的关联。为了确定这种关联是否因认知任务而异。方法使用 Mini-Cog 测量认知障碍，该工具结合了延迟单词回忆任务 (WRT) 和时钟绘制任务 (CDT)，以得出正常与认知障碍的总体分类。参与者是从为服务不足的患者提供护理的初级保健诊所招募的。结果参与者 (n= 574) 主要是非西班牙裔黑人 (67%)，平均年龄为 46 岁，50% 没有健康保险，56% 受过高中或以下教育，21% 的认知障碍筛查呈阳性。在调整其他变量（包括种族/民族和身体健康）后，总体认知能力和教育与健康素养显着相关。我们观察到 CDT 与健康素养之间的关联性比 WRT 与健康素养之间的关联性更强。结论通过确认假设的关联性，本研究为 Health LiTT 的有效性提供了额外的支持。实践意义 Health LiTT 是一种可靠且有效的工具，研究人员和临床医生可以使用它来识别可能难以理解健康信息的个人。
ObjectivesTo confirm the association of health literacy scores as measured by Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT) with cognitive ability and education. To determine whether this association differs by cognitive task.MethodsCognitive impairment was measured using the Mini-Cog, which combines a delayed word recall task (WRT) and a clock drawing task (CDT) to yield an overall classification of normal versus cognitively impaired. Participants were recruited from primary care clinics that provide care to underserved patients.ResultsParticipants (n= 574) were predominantly non-Hispanic black (67%) with a mean age of 46 years, 50% did not have health insurance, 56% had a high school education or less and 21% screened positive for cognitive impairment. Overall cognitive ability and education were significantly associated with health literacy after adjusting for other variables, including race/ethnicity and physical health. We observed a stronger association between the CDT and health literacy than between the WRT and health literacy.ConclusionBy confirming hypothesized associations, this study provides additional support of the validity of Health LiTT.Practice implicationsHealth LiTT is a reliable and valid tool that researchers and clinicians can use to identify individuals who might have difficulty understanding health information.
