Abstract

Aim

This study aimed to translate the Environmental Health Literacy Scale (EHLS) into Turkish and assess its construct validity and internal consistency.

Methods

This research employs a methodological design. The research was conducted during the 2022–2023 academic year with a sample of 500 students from the Faculty of Health Sciences. The data were collected via the introductory information form, the EHLS, and the Environmental Awareness Scale of university students. Subsequently, the data were transferred to the IBM SPSS Statistics 23 and IBM SPSS AMOS 23 software programs. Upon evaluation of the research data, frequency distributions for categorical variables and descriptive statistics for numerical variables were provided. Content validity was evaluated through the acquisition of expert approval. Confirmatory factor analysis was employed for scale validity, while Cronbach's α, test–retest and parallel form analyses were utilized for reliability.

Results

The content validity index of the scale was determined to be 1.00. The scale is constituted of four discrete scales (general, food, air and water), each comprising three dimensions. In consideration of the fit indices, specifically the χ²/df, GFI, TLI, IFI, CFI, RMSEA and SRMR, it can be concluded that the general, food, air and water scales are deemed acceptable. Cronbach's α coefficients for the scales were found to be 0.70, 0.81, 0.83 and 0.79, respectively. In the parallel form analysis, a statistically significant positive relationship was identified between the scales.

Conclusions

The findings of this research indicate that the scale is a reliable instrument for assessing the environmental health literacy levels of undergraduate students enrolled in health sciences programs. It is anticipated that the scale will contribute to the advancement of environmental health literacy awareness.

土耳其版环境健康素养量表的效度和信度。

目的：本研究旨在将环境健康素养量表（EHLS）翻译成土耳其文，并评估其结构效度和内部一致性。方法：采用方法学设计。这项研究是在2022-2023学年进行的，样本是来自健康科学学院的500名学生。本研究采用介绍信息表、环境调查问卷和大学生环境意识量表收集数据。随后，将数据转入IBM SPSS Statistics 23和IBM SPSS AMOS 23软件程序。在评估研究数据后，提供了分类变量的频率分布和数值变量的描述性统计。通过获得专家认可来评估内容效度。效度采用验证性因子分析，信度采用Cronbach’s α、重测、平行形式分析。结果：确定量表的内容效度指数为1.00。该量表由四个独立的量表（一般、食物、空气和水）组成，每个量表由三个维度组成。考虑到拟合指标，特别是χ2/df、GFI、TLI、IFI、CFI、RMSEA和SRMR，可以得出结论，一般尺度、食品尺度、空气尺度和水尺度是可以接受的。量表的Cronbach’s α系数分别为0.70、0.81、0.83和0.79。在平行形式分析中，量表之间存在统计学上显著的正相关。结论：本研究结果表明，该量表是评估健康科学专业本科生环境健康素养水平的可靠工具。预计该比额表将有助于提高对环境卫生知识的认识。

期刊介绍： The Journal of Evaluation in Clinical Practice aims to promote the evaluation and development of clinical practice across medicine, nursing and the allied health professions. All aspects of health services research and public health policy analysis and debate are of interest to the Journal whether studied from a population-based or individual patient-centred perspective. Of particular interest to the Journal are submissions on all aspects of clinical effectiveness and efficiency including evidence-based medicine, clinical practice guidelines, clinical decision making, clinical services organisation, implementation and delivery, health economic evaluation, health process and outcome measurement and new or improved methods (conceptual and statistical) for systematic inquiry into clinical practice. Papers may take a classical quantitative or qualitative approach to investigation (or may utilise both techniques) or may take the form of learned essays, structured/systematic reviews and critiques.
