Studying environmental identity is crucial for understanding diverse relationships between people and the natural world, which has direct implications for fostering pro-environmental attitudes and behaviors. The aim of this research was to adapt the Ecological Identity Scale into Serbian and examine the psychometric characteristics of the adapted version in comparison to the original version, using a sample of participants from Serbia. The sample consisted of 146 participants (Mage = 34.21, SDage = 13.41, Min = 18, Max = 67), of whom 66.4% were female. To assess the construct validity of the adapted scale, confirmatory factor analysis was conducted. The results indicate that the same number of dimensions showed in both the original and adapted versions of the scale (sameness, differentiation and centrality). The assessment of convergent validity, conducted by comparing the scores obtained on the Ecological Identity Scale with those from the Revised Ecological Identity Scale and the New Ecological Paradigm Scale, supports the scale’s convergent validity. The nomological network of the adapted version was examined by calculating correlations between the Ecological Identity Scale scores and measures of self-transcendence and self-enhancement, with the results largely supporting its equivalence to the nomological network of the original scale. The internal validity of the scale was assessed through the relationships between its measures, and the results support this aspect of validity. The scale demonstrated satisfactory internal consistency reliability in the current sample. Despite the study’s limitations, the adapted version of the scale can be used for assessing ecological identity with some caution and primarily for research purposes to allow for potential modifications of the instrument.
