Psychometric Properties of the Turkish Version of the Climate and Health Tool (CHAT) for Health Professionals: A Validity and Reliability Study

Climate change presents critical challenges to public health, and healthcare professionals play a vital role in addressing its effects. The Climate and Health Tool (CHAT) assesses awareness, concern, motivation, and behaviors regarding climate change and health. This study aimed to adapt the CHAT into Turkish and evaluate its psychometric properties among healthcare professionals in Türkiye. A cross-sectional validation study was conducted with 496 participants using international adaptation standards, including forward-backward translation and cognitive interviews. Confirmatory factor analysis confirmed the original five-factor structure with excellent model fit (RMSEA = .038, CFI = .971). Internal consistency was high (Cronbach's α = .886), and convergent validity was supported through positive correlations with the Carbon Footprint Awareness Scale and Climate Change Worry Scale. Measurement invariance testing demonstrated equivalence across gender groups. The Turkish CHAT is a valid and reliable tool for assessing climate-health competencies in research, education, and clinical settings.
