Abstract

This study reports the results of two meta-analyses investigating the effects of political variables on environmental concern. Political party affiliation was found to have a substantial impact on environmental concern, ρ = .22, and the effect of political ideology was even stronger, ρ = .38. Both effects could also be corrected for error of measurement and restriction in range, yielding corrected effect sizes of ρ’ = .35 and ρ’ = .54, respectively. Moreover, both effects were found to be moderated by the educational level of the sample, the measure of environmental concern employed, and the year in which the study was conducted.
