Measuring biospheric values: Italian adaptation of the GREEN scale

Climate change is requiring people to shift toward more sustainable lifestyles. Although the contri-bution of behavioral sciences in sustainability domains is growing, validated instruments to measure biospheric values are still few, especially in Italian. The present study aims to test the psychometric properties of the GREEN scale in Italian, by adopting the best practices suggested by the contemporary view of validity. Data was retrieved from a representative sample of 1,002 Italian individuals, split into two subgroups. Both exploratory and confirmatory factor analyses supported the original factorial struc-ture of the scale and the measurement invariance showed that this structure is equivalent across genders. Furthermore, convergent, discriminant, and criterion-related validity evidence demonstrated that the measure is associated with universalism, connectedness to nature, and daily pro-environmental behav-iors, respectively. Collected evidence suggests that the GREEN scale is a valid and reliable measure for biospheric values.
