“…However, not all studies support these differences, as a number of studies demonstrate that either there are no gender differences in environmental concern (e.g., Alibeli & White, 2011;Arcury & Masculinity, Femininity and Attitudes / Masculinidad, Feminidad y Actitudes 285 Christianson, 1993; Hayes, 2001;Olofsson & Ohman, 2006;Wiidegren, 1998) or that men present greater concern (e.g., Arbuthnot, 1977;Arcury, Scollay, & Johnson, 1987;MacDonald & Hara, 1994;McEvoy, 1972). Therefore, the results obtained up until now have been somewhat contradictory and inconclusive (Arcury et al, 1987;Hayes, 2001;Hines, Hungerford, & Tomera, 1987;Mohai, 1992;Van Liere & Dunlap, 1980). One possible explanation for this disparity of results comes from one of the theoretical frameworks that attempt to explain the gender differences in proenvironmental attitudes and behaviours, namely the Theory of Gender-Role Socialization (Bem, 1974;Eagly, 1987;Unger & Crawford, 1996).…”
