The aim of this study was to investigate whether a self-report measurement instrument (the Brief Health Literacy Screen, BHLS) correctly identifies healthcare consumers with inadequate health literacy. The yardstick for assessing the tool was the Newest Vital Sign (NVS).
The study used baseline data from the Västerbotten Intervention Programme - VIsualiZation of Asymptomatic Atherosclerotic disease for Optimum Cardiovascular Prevention (VIPVIZA), a randomized controlled trial that is nested within the Västerbotten Intervention Program (VIP) in Sweden. Our analyses were computed on a subsample of 460 persons who underwent the measure of both health literacy scales. ROC analysis was used for the crucial computations.
The potential of the BHLS to identify healthcare consumers with inadequate health literacy remained unsatisfying for the complete sample, but reached an acceptable level for women and persons with only basic education.
The relationship is somewhat weaker than in comparable research in various other European countries. The differences might partly have been caused by the use of self-perception questions. Self-delusions, invariably a part of self-perception, may have affected the respective measure.
Caution is advised when patients' health literacy is assessed by only a few questions for self-report.
本研究旨在探讨自报测量工具（简短健康素养筛查工具，BHLS）是否能正确识别健康素养不足的医疗消费者。评估工具的标准是最新生命体征（NVS）。
本研究使用了瑞典 Västerbotten 干预计划 - 无症状动脉粥样硬化疾病可视化以实现最佳心血管预防（VIPVIZA）的基线数据，这是一个嵌套在 Västerbotten 干预计划（VIP）中的随机对照试验。我们的分析是基于接受了两种健康素养量表测量的 460 名参与者的子样本进行计算的。ROC 分析用于关键计算。
对于整个样本，BHLS 识别健康素养不足的医疗消费者的能力仍不令人满意，但对于女性和仅接受基本教育的人来说，其能力达到了可接受的水平。
与其他欧洲国家的类似研究相比，这种关系稍弱。差异的部分原因可能是使用了自我感知问题。自我错觉，总是自我感知的一部分，可能会影响各自的测量。
仅通过自我报告的几个问题评估患者的健康素养时应谨慎。
