Previous qualitative studies have identified themes of generativity and identity development in the interviews of environmental activists (Chan, 2009; Horwitz, 1996), suggesting their importance as motives for environmental behavior. The purpose of our study was to extend this work by identifying positive relationships between identity maturity, generativity, and environmentalism using quantitative methodologies. To explore these relationships, we designed quasi-experimental and correlational studies. We recruited 54 environmental activists and 56 comparison individuals, half of whom were youth (mean age = 22 years) and the other half midlife adults (mean age = 43 years). Sixty-three percent of our sample was female. Participants completed several environmental, generativity, and identity questionnaires. We found that activists and comparison individuals differed on the identity maturity, generativity, and environmental measures overall. Further, greater identity maturity and generativity were associated with higher environmental engagement. And generativity was found to mediate the relation between identity maturity and environmentalism. Our findings suggest that engaging in generative behaviors may be an important part of the process in forming an environmental identity and engaging in environmental actions.
