|Bogner, FX; Wiseman, M: Adolescents' attitudes towards nature and environment: Quantifying the 2-MEV model, The Environmentalist , 26, 247-254 (2006)|
A questionnaire battery designed to measure the factors Utilization (U) and Preservation (P) in the field of adolescent environmental perception was administered to 467 German secondary school pupils. Maximum likelihood factor analysis yielded the two hypothesized orthogonal factors U and P; we labelled this scale the 2-MEV model, i.e. the 2 factor Model of Environmental Attitudes as dispositions. These analyses provide a basis for the construction of a questionnaire specifically designed to measure U and P. Confirmation of this factor structure was examined by comparing the factors extracted from two independent pseudorandom subsamples selected from the original sample.
