The principal objective of this research is to test the factorial structure of the New Ecological Paradigm scale on a population of men and women residing in France. The tested model is a second-order factorial model. This factorial structure is evaluated on two separate samples to test the stability of the solution (a first sample of 253 participants, diversified in terms of age and socioprofessional category, and a second sample of 266 students). The results confirm the existence of a second-order factorial structure in which environmental beliefs, measured based on 13 items taken from the New Ecological Paradigm scale, would constitute a homogeneous system of beliefs supported in five distinct dimensions.
