OBJECTIVE
To evaluate the psychometric properties of a newly developed Medication Literacy Assessment in Spanish and English (MedLitR xSE).
DESIGN
Descriptive, nonexperimental, cross-sectional study.
SETTING
El Paso, TX, from December 2006 to June 2009.
PARTICIPANTS
181 English- or Spanish speaking adults.
INTERVENTION
Survey administered in two phases.
MAIN OUTCOME MEASURES
Descriptive statistics, internal consistency, confirmatory factor analysis (CFA) and fit indices, and criterion-related validity.
RESULTS
The 20-item MedLitR xSE tool showed adequate internal consistency and reliability, and CFA revealed overall good model fit. In phase 2, the shorter 14-item MedLitR xSE showed good total test reliability and correlated well with the Short Test of Functional Health Literacy in Adults. Item response theory analyses showed no language bias and a one-dimensional (i.e., one factor) model of medication literacy.
CONCLUSION
The initial and latest shorter version of the MedLitR xSE tool demonstrated good psychometric properties. This tool may provide a new option to assess "medication literacy" in English and Spanish.
目的
评估新开发的英文和西班牙文药物素养评估工具（MedLitR xSE）的心理计量学特性。
设计
描述性、非实验性、横断面研究。
地点
2006 年 12 月至 2009 年 6 月，德克萨斯州埃尔帕索。
参与者
181 名讲英语或西班牙语的成年人。
干预措施
调查分两个阶段进行。
主要观察指标
描述性统计、内部一致性、验证性因子分析（CFA）和拟合指数以及效标关联效度。
结果
20 项 MedLitR xSE 工具显示出足够的内部一致性和可靠性，CFA 显示出总体良好的模型拟合度。在第 2 阶段，较短的 14 项 MedLitR xSE 显示出良好的总测试可靠性，并与成人简易功能性健康素养测试（Short Test of Functional Health Literacy in Adults）相关良好。项目反应理论分析显示没有语言偏差和药物素养的一维（即一个因素）模型。
结论
MedLitR xSE 工具的初始和最新较短版本显示出良好的心理计量学特性。该工具可能为评估英语和西班牙语中的“药物素养”提供了新的选择。
