虽然成人功能性健康素养短期测试（S-TOFHLA）被广泛使用，但在特定的健康素养（HL）维度（如算术）中，对健康素养（HL）低的个体的错误识别是一个问题。我们通过两个额外的数值测量来检查在S-TOFHLA上评分为“足够”HL的个体被认为具有低HL的程度。年龄在45-75岁之间的讲英语的成年人从美国的一个大型城市学术医疗中心和一个社区食品银行招募。参与者完成了S-TOFHLA，主观计算能力量表（SNS）和图形素养测量（GL），这是一种客观衡量一个人解释图形数字信息能力的方法。既定的分界点或中位数分裂分类参与者，并具有高和低的算术。参与者（n = 187），平均年龄为：58岁; 63%的女性; 70%的黑人/非洲裔美国人;和45%有高中学历或更低。在那些谁得分“足够”的S-TOFHLA，50%得分低的SNS和40%得分低的GL。S-TOFHLA与SNS总评分之间的相关性为中度（r = 0.22，n = 186，p = 0.01），而S-TOFHLA与GL总评分之间的相关性较大（r = 0.53，n = 187，p ≤ 0.01）。研究结果表明，S-TOFHLA可能无法捕获个人的HL在计算的维度。需要努力开发更全面、更实用的策略来识别低HL患者，以用于研究和临床实践。NCT 02151032（回顾性登记：2014年5月30日）。
Although the Short Test of Functional Health Literacy in Adults (S-TOFHLA) is widely used, misidentification of individuals with low health literacy (HL) in specific HL dimensions, like numeracy, is a concern. We examined the degree to which individuals scored as “adequate” HL on the S-TOFHLA would be considered as having low HL by two additional numerical measures. English-speaking adults aged 45–75 years were recruited from a large, urban academic medical center and a community foodbank in the United States. Participants completed the S-TOFHLA, the Subjective Numeracy Scale (SNS), and the Graphical Literacy Measure (GL), an objective measure of a person’s ability to interpret numeric information presented graphically. Established cut-points or a median split classified participants and having high and low numeracy. Participants (n = 187), on average were: aged 58 years; 63% female; 70% Black/African American; and 45% had a high school degree or less. Of those who scored “adequate” on the S-TOFHLA, 50% scored low on the SNS and 40% scored low on GL. Correlation between the S-TOFHLA and the SNS Total was moderate (r = 0.22, n = 186, p = 0.01), while correlation between the S-TOFHLA and the GL Total was large (r = 0.53, n = 187, p ≤ 0.01). Findings suggest that the S-TOFHLA may not capture an individuals’ HL in the dimension of numeracy. Efforts are needed to develop more encompassing and practical strategies for identifying those with low HL for use in research and clinical practice.
