Climate change perception scale: Adaptation and psychometric properties in the Indonesian context

One of the crucial factors in changing behaviour towards pro-environmental actions is climate change perception. The latest measurement tool for assessing this variable is the Climate Change Perception Scale (CCPS). However, CCPS has not gained widespread adoption and usage across different cultures, including Indonesia, and no analyses have been conducted to adapt and validate CCPS in the Indonesian context. Therefore, this study aimed to adapt, validate, and assess the measurement tool's consistency in Indonesia's cultural context. To investigate the instrument's psychometric properties, two studies (n = 358, 415) were conducted in Indonesia to provide evidence of the internal consistency, convergent validity, and predictive validity of CCPS. The results of a confirmatory factor analysis (CFA) showed that the Indonesian version of CCPS, which consists of 15 items, with three for each dimension, accurately and reliably measured perception of climate change. CCPS also demonstrated good convergent validity, as indicated by the significant correlations with a nature relatedness (r = 0.425, p < 0.01) and biospheric value (r = 0.341, p < 0.01) construct. Furthermore, it exhibited predictive validity by predicting pro-environmental behaviour, β = 0.243, b = 0.176, t(413) = 5.10, p < 0.01. However, the Indonesian version of CCPS still needs to be tested and confirmed through various studies, considering the poor validity of the temporal dimension and the weak factor loading of the consequence dimension in Study 2.
