    A relevant intrapersonal characteristic for understanding intentions and behavior toward environmental sustainability is the degree to which nature is important for a person’s self-definition. Clayton’s Environmental Identity (EID) scale purports to measure this construct. However, a limited number of prior exploratory studies of this measure have supported different factor structures. Hence, our initial aim was to develop an understanding of the dimensionality of Clayton’s 24-item EID scale by testing competing latent structures using confirmatory factor analysis. We analyzed self-reported data from 458 adults (Mage = 26.7 years; 81% female). Four a priori models (a first-order model, a second-order model, a unidimensional model, and a bifactor model) did not show satisfactory fit to the data. An ancillary analysis using bifactor exploratory structural equation modeling (bifactor-ESEM) indicated a bifactor model with three specific factors had a good fit to the data. The factor loadings of this model and values for bifactor indices (Omega Hierarchical and Explained Common Variance [ECV]) indicated a single mean score across all EID scale items taps into an essentially unidimensional construct and is therefore appropriate to interpret. In sum, our study provides a critical insight into the dimensionality of Clayton’s EID scale that will be valuable when applying this measure for research and intervention purposes.

    Effects of contact with nature on connectedness, environmental identity and evoked contents
    (Edições Universitárias Lusófonas, 2020) Mena-García, Antonio; Olivos-Jara, Pablo; Loureiro, Ana Luisa Cardoso Marques Teixeira; Navarro, Oscar; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Natural experiences influence identity and the way of interacting with the environment, and their effects are varied, including wellbeing and positive thoughts towards nature. This study analyses the effects produced as a result of real or virtual experiences of nature. A total of 288 people took part in this research, distributed among three experimental conditions: nature walk, images of nature and control group. Changes were registered in terms of connectedness and environmental identity, caused by the experimental conditions and differences in the free evocations generated. Connection to nature was higher among those who took part in the nature walks, related to the evocation of positive emotions, memories of social experiences in nature and pro-environmental reflections. These results are interesting for the field of environmental education and the promotion of environmental values and behaviours.
