Abstract

Introduction

This study aims to develop and validate a psychometric tool—the Climate Change Perceptions Scale for Health and Related Professionals and Students (CCPS-HARPS)—to assess the perceptions of health professionals and students regarding climate change and its impacts on health, and to evaluate its reliability and validity.

Methods

A sequential exploratory mixed-method approach was utilized for the development and validation of CCPS-HARPS. The process included an extensive literature review, expert consultations, and iterative feedback. The initial scale, comprising 37 items, was reduced to 30 items after qualitative analysis. Content validity was assessed using the Lawshe technique, and the final version included 29 items. The scale was pilot-tested among health students at İzmir Democracy University. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to evaluate construct validity, and internal consistency was determined using Cronbach’s alpha and McDonald's omega coefficients.

Results

The sample included 304 valid responses. The Kaiser-Meyer-Olkin (KMO) measure was 0.937, and Bartlett's Test of Sphericity confirmed the data's suitability for factor analysis. EFA revealed a three-factor structure (Awareness and Consciousness, Experiences and Effects, and Health and Climate Change) that explained 50.96 % of the total variance. CFA supported the three-factor model with excellent fit indices (RMSEA = 0.045, SRMR = 0.054, CFI = 0.995). Internal consistency was high, with Cronbach’s alpha and McDonald’s omega values exceeding 0.90 for the total scale.

Conclusion

The CCPS-HARPS is a reliable and valid instrument for assessing climate change perceptions among health professionals and students. It addresses the gap in tools tailored for healthcare-related fields and can inform educational strategies to enhance climate change preparedness. Further studies are recommended to explore its applicability across different cultural and educational settings.

气候变化感知量表（CCPS-HARPS）的编制、信度和效度

摘要本研究旨在开发并验证一种心理测量工具——卫生及相关专业人员和学生气候变化感知量表（CCPS-HARPS），以评估卫生专业人员和学生对气候变化及其对健康影响的感知，并评估其信度和效度。方法采用顺序探索性混合方法对CCPS-HARPS进行开发和验证。这一过程包括广泛的文献回顾、专家咨询和反复反馈。最初的量表有37个项目，经过定性分析，减少到30个项目。使用Lawshe技术评估内容效度，最终版本包括29个项目。该量表在İzmir民主大学的卫生专业学生中进行了试点测试。采用探索性因子分析（EFA）和验证性因子分析（CFA）评估结构效度，并采用Cronbach 's alpha和McDonald's omega系数确定内部一致性。结果共收集有效问卷304份。Kaiser-Meyer-Olkin （KMO）测度为0.937，Bartlett球性检验证实数据适合因子分析。全民教育揭示了一个三因素结构（意识和意识，经验和影响，健康和气候变化），解释了总方差的50.96%。CFA支持三因素模型，拟合指数很好（RMSEA = 0.045, SRMR = 0.054, CFI = 0.995）。内部一致性高，总量表的Cronbach’s alpha和McDonald’s omega值均超过0.90。结论CCPS-HARPS是一种可靠、有效的评估卫生专业人员和学生气候变化认知的工具。它解决了为卫生保健相关领域量身定制的工具方面的差距，并可为加强气候变化防范的教育战略提供信息。建议进一步研究以探索其在不同文化和教育环境中的适用性。
