Podsumowanie	The Environmental Identity Scale (EIS) measures the degree to which individuals incorporate environmental values and ecological concerns into their sense of self—how central environmental stewardship is to personal identity and self-concept. Developed by Clayton (2003) from identity theory and social psychology, the EIS captures environmental identity as a psychological construct distinct from attitudes, values, or behaviors alone. High EIS scores indicate that individuals view themselves as 'environmental people' for whom conservation and sustainability are integral to who they are. The scale is foundational for research on sustainable behavior motivation, examining why environmental values persist and translate into behavior for some individuals but not others, and evaluating whether environmental interventions shift identity and thus self-motivated behavior change.	The Connectedness to Nature Scale (CNS) measures the degree to which individuals feel emotionally and cognitively connected to nature as part of their sense of self. Developed by Mayer and Frantz (2004), the CNS operationalizes the construct of nature connection—the felt sense of kinship, interdependence, and belonging with the natural world. The scale is widely employed in environmental psychology research, health outcome studies examining nature exposure effects, and intervention evaluations designed to strengthen human-nature relationships.
