Measuring Environmental Perceptions Grounded on Different Theoretical Models: The 2-Major Environmental Values (2-MEV) Model in Comparison with the New Ecological Paradigm (NEP) Scale

Our study examined the two-dimensional nature of the Two Major Environmental Values model (2-MEV) in comparison with the New Ecological Paradigm (NEP) scale's unidimensional construct. The latter places respondents on a continuum from a bio-centric to anthropocentric worldview, where an individual can either have a pro-environmental (bio-centric) or an anti-environmental (anthropocentric) perspective, but not both. On the other hand, the 2-MEV treats biocentrism (Preservation, PRE) and anthropocentrism (Utilization, UTL) as two separate and not necessarily related components. The model allows us to place individuals into one of four quadrants, rather than on either end of a continuum, allowing an individual to have a bio-centric and an anthropocentric worldview at the same time. Students' environmental perceptions were measured using the NEP and 2-MEV questionnaires. As predicted, high preservation/low utilization scorers preferred a biocentric worldview on the NEP; similarly, low preservation/high utilization scorers preferred an anthropocentric worldview on the NEP. However, the NEP failed to differentiate between the high preservation/high utilization and low preservation/low utilizations scorers. Both of these groups of students, while on different quadrants on the 2-MEV, cluster together in the middle of the unidimensional NEP. Evidence suggests that the NEP may not fully explore all dimensions of environmental perceptions.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
