- Adaptation of the eco-anxiety scale to adult Portuguese native speakers: a validity and reliability studyPublication . Ferrajão, Paulo; Torres, Nuno; Martins, Amadeu QuelhasEco-anxiety is a multidimensional construct that includes emotional, behavioral and cognitive manifestations related to potential environmental calamities. There is a need to adapt and validate measures that evaluate eco-anxiety into Portuguese using a multi-trait approach. This study examined the psychometric properties of the Hogg Eco-Anxiety Scale (HEAS) in adult Portuguese speakers (18–83 years old). Data were collected on the Portuguese adaptation of the HEAS, environmental identity and psychological symptoms, and sociodemographic data. The construct validity of the HEAS was subsequently examined through exploratory and confirmatory factor analysis. The factorial structure of the original scale was the best explanation of the sample data. The scale showed good internal consistency and presented measurement invariance for both sex and age groups. The global score of the HEAS and the dimensions of emotional and behavioral symptoms were moderately associated with clinical symptoms. Females and younger participants presented higher levels of eco-anxiety apart from rumination symptoms. The results suggest the suitability of the HEAS as a valid measure to evaluate the different signs of eco-anxiety among adult Portuguese native speakers.
- Adaptation of the Revised Environmental Identity Scale to Adult Portuguese Native Speakers: A Validity and Reliability StudyPublication . Ferrajão, Paulo; Torres, Nuno; Martins, Amadeu QuelhasEnvironmental identity is a dimension of personal identity that reflects an individual’s sense of connection with nature and personal view of nature as part of her/his identity. There is a need to adapt and validate measures that assess environmental identity, namely in Portuguese. This study analyzed the validity and reliability of the Revised Environmental Identity Scale (Revised EID) in a sample of native speakers of Portuguese from 18 to 83 years old. The survey included the Portuguese translation of the Revised EID, measures of eco-anxiety, adult attachment, affective neurobiological systems, psychological symptoms, and sociodemographic information. Exploratory and confirmatory factor analyses were conducted to assess the construct validity of the scale. It was tied to a two-factor solution (Connectedness with Nature and Protection of Nature) found in prior research. The Revised EID was positively related to feelings of anxiety about personal impact on climate change and positive emotional systems (SEEKING, CARE, and PLAY). Older participants reported higher levels in the overall environmental identity score and the Protection of Nature factor. The results indicate that the Revised EID is an appropriate measure to assess environmental identity in adult Portuguese native speakers and should be used to conduct cross-cultural studies to drive environmental and health policies.
