Validating a measure for eco-anxiety in Portuguese young adults and exploring its associations with environmental action.

BACKGROUND: Worsening environmental conditions may amplify people's emotional responses to an environmental crisis (eco-anxiety). In Portugal, young people seem to be especially concerned about climate change. However, this phenomenon needs to be interpreted using accurate instruments. Thus, this study aimed to validate the Portuguese version of the Hogg Eco-Anxiety Scale (HEAS) in young adults and examine the associations among eco-anxiety, sociodemographic characteristics, and pro-environmental behaviours. METHODS: A survey was administered to 623 Portuguese university students aged between 18 and 25 years. The survey included our Portuguese translation of the HEAS (obtained through a back-translation and pretesting process), a sociodemographic assessment, and questions related to pro-environmental behaviours. Confirmatory factor analysis was conducted to assess the construct validity of the Portuguese version of the HEAS, and global fit indices were used to assess whether the original four-dimensional structure of the scale was reproduced. The reliability of the Portuguese version of the HEAS was evaluated by Cronbach's alpha and the intraclass correlation coefficient. Measurement invariance examined sex differences in scale interpretation. Linear regressions were used to detect whether sociodemographic variables predict eco-anxiety and whether eco-anxiety predicts pro-environmental behaviours. RESULTS: The factorial structure of the original scale was replicated in the Portuguese version of the HEAS, showing good internal consistency, reliability over time and strict invariance between men and women. A higher paternal education level predicted greater eco-anxiety in children. Two dimensions of eco-anxiety-namely, rumination and anxiety about personal impacts on the environment-predicted higher engagement in pro-environmental behaviours. CONCLUSIONS: The translated scale is an appropriate tool to measure eco-anxiety in the Portuguese context and should be used to collect evidence to drive environmental and health policies. An individual's education level should be considered a determinant of their emotional response to environmental conditions. Importantly, eco-anxiety can act as a protective emotional response to preserving the planet.

Validation of the Argentine version of the epistemic trust, mistrust, and credulity questionnaire.

Epistemic trust refers to the trust in communicated knowledge, specifically an individual's ability to regard knowledge conveyed by others as meaningful, relevant to oneself, and applicable to other contexts. This area has received considerable attention in recent psychological literature, though predominantly from a theoretical perspective. The main objective of this study was to test the factorial validity of the Epistemic Trust, Mistrust, and Credulity Questionnaire (ETMCQ) on an Argentine setting. Based on two studies (Study 1, n = 1018; Study 2, n = 559), the factorial structure of the instrument and its internal consistency were examined (S1 Appendix). In the second study, the factorial structure was confirmed, test-retest reliability was analysed, and associations between epistemic stances and sociodemographic variables, hypomentalisation, attachment styles, childhood traumatic experiences, and anxious-depressive symptomatology were explored. A satisfactory three-factor solution with 15 items and residual correlations was found in both studies, with stable scores over time. Significant positive correlations were found with anxious and fearful-avoidant attachment, hypomentalisation, childhood traumatic experiences, and psychopathological symptomatology. Post-hoc analysis revealed that, on the one hand, gender acts as a moderator in the relationship between hypomentalisation and epistemic mistrust. On the other hand, economic level and educational level moderate the relationship between hypomentalisation and epistemic credulity. Measurement invariance across gender was tested and found satisfactory, with significant differences subsequently observed in the epistemic trust factor. In conclusion, the Argentine version of the ETMCQ provides an empirical measure for use in non-clinical samples. Its application could facilitate clinically and theoretically relevant findings.

Mental health during ecological crisis: translating and validating the Hogg Eco-anxiety Scale for Argentinian and Spanish populations.

BACKGROUND: Eco-anxiety is increasingly recognized as a shared experience by many people internationally, encompassing fear of environmental catastrophe and anxiety about ecological crises. Despite its importance in the context of the changing climate, measures for this construct are still being developed in languages other than English. METHODS: To contribute to global eco-anxiety research, we translated the Hogg Eco-Anxiety Scale (HEAS) into Spanish, creating the HEAS-SP. We validated this measure in samples from both Argentina (n = 990) and Spain (n = 548), performing measurement invariance and confirmatory factor analyses. Internal consistency of the scale and score stability over time were investigated through reliability analyses. Differences in eco-anxiety across sociodemographic variables were explored through Student's t-tests and Pearson's r tests. RESULTS: The four-factor model of the HEAS-SP comprising affective and behavioural symptoms, rumination, and anxiety about personal impact demonstrated excellent model fit. We found good internal consistency for each subscale, and established measurement invariance between Spanish and Argentine samples, as well as across genders and participants' age. Spanish participants reported higher scores on the affective symptoms and personal impact anxiety factors compared to the Argentinian sample. Also, men reported lower levels than women on the subscales of affective symptoms, rumination, and personal impact anxiety. It was found that the relationship between both age and personal impact anxiety and age and affective symptoms varies significantly depending on the gender of the individuals. Younger participants tended to report higher scores on most dimensions of eco-anxiety. CONCLUSIONS: These findings enhance the global initiative to investigate, explore and therefore comprehend eco-anxiety by introducing the first valid and reliable Spanish-language version of this psychometric instrument for its use within Spanish and Argentinian populations. This study augments the body of evidence supporting the robust psychometric properties of the HEAS, as demonstrated in prior validations for Australian, Turkish, Portuguese, German, French, and Italian populations.
