Abstract

The aim of this study is to evaluate the psychometric properties and factorial invariance of the Climate Change Attitude Scale (CCAS). Based on Planned Behavior Theory, the scale measures both beliefs and behavioral intentions towards climate change. The original instrument consists of 15 items, using a five-point Likert response format. It was applied to a non-probabilistic sample of 800 Chilean participants. After translation and review, the scale demonstrated adequate content validity. A Confirmatory Factor Analysis (CFA) validated the instrument's suitability, which was adjusted to 13 items while maintaining its original two-factor structure. The invariance analysis confirmed that the bidimensional structure is not affected by gender. Evidence was found of convergent and discriminant validity, as well as adequate reliability in both dimensions. In conclusion, we support use of the Spanish version of the CCAS in Spanish-speaking communities, thus strengthening climate change research in the region from a psychosocial perspective. © 2024 Universidad Catolica del Uruguay.
