健康素养是指获取、理解、评价和应用健康信息的个人能力，以便在日常生活中做出正确的决定。本研究的目的是开发和评估一种测量青少年健康素养的工具（青少年健康素养测量- helma）的心理测量特性。本研究由定性和定量两个阶段组成，于2012-2014年在伊朗德黑兰进行。在研究的定性部分，对4所高中的67名15-18岁的青少年进行了深度访谈，以产生调查的初始项目池。然后通过专家小组审查评估项目的内容效度（n = 13），并通过采访青少年（n = 16）来评估面部效度。在研究的定量部分，为了描述量表的心理测量特性，对效度、信度（内部一致性和重测）和因子分析进行了评估。在定性阶段产生了一个由104个项目组成的项目池。在考虑内容效度后，这一数字减少到47项。在定量阶段，582名15-18岁的青少年参与了研究，平均年龄为16.2岁。51.2%的参与者为女性。主成分因子分析共加载8个因子，占观察方差的53.37%。信度通过α = 0.93得到认可，每隔两周重新测试一次表明该量表具有适当的稳定性（ICC = 0.93）。最终通过的问卷共有44个项目，分为8个部分。这些章节的标题是：获取、阅读、理解、评估、使用、交流、自我效能和计算能力。青少年健康素养测量（HELMA）是衡量15-18岁青少年健康素养的有效和可靠工具，可用于评估青少年不同水平的功能性、互动性和关键性健康素养。
Health literacy refers to personal competencies for the access to, understanding of, appraisal of and application of health information in order to make sound decisions in everyday life. The aim of this study was to develop and evaluate the psychometric properties of an instrument for the measurement of health literacy among adolescents (the Health Literacy Measure for Adolescents-HELMA). This study was made up of two phases, qualitative and quantitative, which were carried out in 2012–2014 in Tehran, Iran. In the qualitative part of the study, in-depth interviews with 67 adolescents aged 15–18 were carried out in 4 high schools to generate the initial item pool for the survey. The content validity of the items was then assessed by an expert panel review (n = 13) and face validity was assessed by interviewing adolescents (n = 16). In the quantitative part of the study, in order to describe the psychometric properties of the scale, validity, reliability (internal consistency and test-retest) and factor analysis were assessed. An item pool made up of 104 items was generated at the qualitative stage. After content validity was considered, this decreased to 47 items. In the quantitative stage, 582 adolescents aged 15–18 participated in the study with a mean age of 16.2 years. 51.2% of participants were females. In principal component factor analysis, 8 factors were loaded, which accounted for 53.37% of the variance observed. Reliability has been approved by α = 0.93 and the test-retest of the scale at two-week intervals indicated an appropriate stability for the scale (ICC = 0.93). The final questionnaire was approved with 44 items split into eight sections. The sections were titled: gain access to, reading, understanding, appraise, use, communication, self-efficacy and numeracy. The Health Literacy Measure for Adolescents (HELMA) is a valid and reliable tool for the measurement of the health literacy of adolescents aged 15–18 and can be used to evaluate different levels of functional, interactive, and critical health literacy in adolescents.
