Abstract
The measurement of pro-environmental behaviours is essential to promote the development of sustainable lifestyles, especially within school education. However, there are few such instruments designed specifically for the adolescent population in Spanish and adapted to Latin American contexts. The study presented in this article has drawn on the General Environmental Behaviour Scale for adolescents to design a new scale to measure pro-environmental behaviour among Chilean teenagers. Data were collected from four samples of Chilean teenagers ( n s = 181, 753, 529 and 585) to study the psychometric behaviour of the instrument using a mixed methodology, generating evidence of validity based on content, response processes, internal structure and relationship with other variables. The final scale has 34 items and encompasses dichotomous and polytomous items. It has a one-dimensional structure, with a reliability of .90. Therefore, in this article, we present a relevant tool, with valid interpretations to measure pro-environmental behaviours among Chilean teenagers, and discuss the scope and limitations of the instrument.
