An integrative model of environmentalism has been presented by Stern (2000) which includes not only attitudinal variables, but also personal capabilities, contextual (interpersonal) and social structural variables. It is supposed that different varieties of environmentalism (types of ecological behavior) are associated with a specific set of determinants. This approach regards environmentalism as a joint product of social structural, socialization and social psychological processes. Dietz et al (1998) have made the first effort to assess inductively the relative impact of various social structural and sociopsychological factors in shaping environmentalism, using regression analysis of the data from a representative national sample. In general, social psychological variables appeared to have greater explanatory power than social structural variables, but their effect varied for different indicators of environmentalism (self-reported behavior and environmental beliefs). Our study will follow the same logic.
