Abstract

OBJECTIVE

The study was intended to develop and validate a health literacy test, termed the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA), for the Spanish-speaking population.

STUDY DESIGN

The design of SAHLSA was based on the Rapid Estimate of Adult Literacy in Medicine (REALM), known as the most easily administered tool for assessing health literacy in English. In addition to the word recognition test in REALM, SAHLSA incorporates a comprehension test using multiple-choice questions designed by an expert panel.

DATA COLLECTION

Validation of SAHLSA involved testing and comparing the tool with other health literacy instruments in a sample of 201 Spanish-speaking and 202 English-speaking subjects recruited from the Ambulatory Care Center at UNC Health Care.

PRINCIPAL FINDINGS

With only the word recognition test, REALM could not differentiate the level of health literacy in Spanish. The SAHLSA significantly improved the differentiation. Item response theory analysis was performed to calibrate the SAHLSA and reduce the instrument to 50 items. The resulting instrument, SAHLSA-50, was correlated with the Test of Functional Health Literacy in Adults, another health literacy instrument, at r=0.65. The SAHLSA-50 score was significantly and positively associated with the physical health status of Spanish-speaking subjects (p<.05), holding constant age and years of education. The instrument displayed good internal reliability (Cronbach's alpha=0.92) and test-retest reliability (Pearson's r=0.86).

CONCLUSIONS

The new instrument, SAHLSA-50, has good reliability and validity. It could be used in the clinical or community setting to screen for low health literacy among Spanish speakers.

摘要

目的

本研究旨在开发并验证一种针对讲西班牙语人群的健康素养测试,即西班牙语成人健康素养简短评估(SAHLSA)。

研究设计

SAHLSA的设计基于医学成人识字率快速评估(REALM),这是已知最易于实施的英语健康素养评估工具。除了REALM中的单词识别测试外,SAHLSA还纳入了一个由专家小组设计的多项选择题阅读理解测试。

数据收集

SAHLSA的验证涉及在从北卡罗来纳大学医疗保健门诊护理中心招募的201名讲西班牙语和202名讲英语的受试者样本中,对该工具与其他健康素养工具进行测试和比较。

主要发现

仅通过单词识别测试,REALM无法区分西班牙语人群的健康素养水平。SAHLSA显著改善了区分度。进行了项目反应理论分析以校准SAHLSA并将该工具精简至50个项目。由此产生的工具SAHLSA - 50与另一种健康素养工具成人功能性健康素养测试的相关性为r = 0.65。在控制年龄和受教育年限的情况下,SAHLSA - 50得分与讲西班牙语受试者的身体健康状况显著正相关(p <.05)。该工具显示出良好的内部信度(Cronbach's alpha = 0.92)和重测信度(Pearson's r = 0.86)。

结论

新工具SAHLSA - 50具有良好的信度和效度。它可用于临床或社区环境,以筛查讲西班牙语人群中的低健康素养情况。
