Measurement of climate change anxiety and its mediating effect between experience of climate change and mitigation actions of Filipino youth

Eco-anxiety, climate change and the 'bottom billion': a plea for better understanding

Climate change poses enormous, rapidly increasing risks to human well-being that remain poorly appreciated. The growing understanding of this threat has generated a phenomenon often called 'eco-anxiety'. Eco-anxiety (and its synonyms) is best documented in the Global North, mostly among people who are better educated and whose reasons for concern are both altruistic and self-interested. However, the populations who are most vulnerable to climate change are disproportionately poor and live in the Global South, where evidence for eco-anxiety (or climate) anxiety is limited, especially among those who have been called the 'bottom billion', approximately the global population's poorest decile. Here, I postulate reasons for this research gap as both ethical and practical. Additionally, the bottom billion experience many disadvantages, some of which plausibly lower their recognition of anthropogenic climate change. These disadvantages include nutritional and health factors that can reduce learning capacity, even if access to formal education exists. Many in this population have limited or no electronic access to information. Furthermore, the relationship between the stresses faced by such populations and climate change is often indirect, potentially also disguising recognition of the role of climate change. The world is characterised by many distressing forms of inequality, one of which is the effective 'invisibilisation' of the bottom billion. This group faces many challenges; some of these may exceed climate change as rational causes for anxiety. However, it is here argued that policy makers should act on their behalf, irrespective of evidence that they experience eco-anxiety.

Measuring young individuals' responses to climate change: validation of the Slovenian versions of the climate anxiety scale and the climate change worry scale

Introduction

While increasing awareness of climate change is needed to address this threat to the natural environment and humanity, it may simultaneously negatively impact mental health. Previous studies suggest that climate-specific mental health phenomena, such as climate anxiety and worry, tend to be especially pronounced in youth. To properly understand and address these issues, we need valid measures that can also be used in non-Anglophone samples. Therefore, in the present paper, we aimed to validate Slovenian versions of the Climate Anxiety Scale (CAS) and the Climate Change Worry Scale (CCWS) among Slovenian youth.

Method

We conducted an online survey in which 442 young individuals (18-24 years) from Slovenia filled out the two central questionnaires and additional instruments capturing other relevant constructs (e.g., general anxiety, neuroticism, and behavioral engagement).

Results

The confirmatory factor analyses results supported the hypothesized factorial structure of the CAS (two factors) and the CCWS (one factor). Both scales also demonstrated great internal reliability. Moreover, the analyses exploring both constructs' nomological networks showed moderate positive associations with similar measures, such as anxiety and stress (convergent validity), and very weak associations with measures they should not be particularly related to, such as narcissism (discriminant validity). Lastly, we found that the CAS and, even more so, the CCWS have unique predictive value in explaining outcomes such as perceived threat, support for climate policies, and behavioral engagement (incremental validity).

Discussion

Overall, Slovenian versions of the CAS and the CCWS seem to be valid, reliable, and appropriate for future studies tackling young individuals' responses to climate change. Limitations of the study and areas for future research are discussed.

Eco-anxiety and environmental sustainability interest: A secondary data analysis

Climate change is an increasingly important global concern, requiring urgent action. To achieve environmental sustainability, identifying the predictors influencing individuals' actions is necessary. Individuals with negative psychological responses to climate change, such as eco-anxiety, are more likely to engage in pro-environmental behaviour. However, eco-anxiety and other perceptions associated with climate change and sustainability can differ based on an individual's unique background. Therefore, this study aimed to identify potent predictors of individuals' environmental sustainability interest and examine the impact of eco-anxiety on environmental sustainability interest. Data from 459 South Korean adults (19-65 years) were included in this secondary analysis. Eco-anxiety, climate change risk perception and future event cognition were assessed by the Climate Change Anxiety Scale, the Climate Change Risk Perception Inventory and Future Event Questionnaires, respectively. Multiple linear regression analysis showed that eco-anxiety was the most potent predictor of environmental sustainability interest, followed by climate change risk perception, age 60-65 years, future event cognition and age under 30 years. Considering that eco-anxiety is the most potent predictor of environmental sustainability interest, mental health nurses should assess patients' eco-anxiety level and help them recognize and manage their anxiety levels appropriately. Age-specific approaches should be considered for interventions to enhance environmental sustainability interest. Further studies are needed to determine the cut-off anxiety level that influences the positive impact on environmental sustainability interest and to develop programmes to manage eco-anxiety.

Anxiety in response to the climate and environmental crises: validation of the Hogg Eco-Anxiety Scale in Germany

Background

As the climate and environmental crises unfold, eco-anxiety, defined as anxiety about the crises' devastating consequences for life on earth, affects mental health worldwide. Despite its importance, research on eco-anxiety is currently limited by a lack of validated assessment instruments available in different languages. Recently, Hogg and colleagues proposed a multidimensional approach to assess eco-anxiety. Here, we aim to translate the original English Hogg Eco-Anxiety Scale (HEAS) into German and to assess its reliability and validity in a German sample.

Methods

Following the TRAPD (translation, review, adjudication, pre-test, documentation) approach, we translated the original English scale into German. In total, 486 participants completed the German HEAS. We used Bayesian confirmatory factor analysis (CFA) to assess whether the four-factorial model of the original English version could be replicated in the German sample. Furthermore, associations with a variety of emotional reactions towards the climate crisis, general depression, anxiety, and stress were investigated.

Results

The German HEAS was internally consistent (Cronbach's alphas 0.71-0.86) and the Bayesian CFA showed that model fit was best for the four-factorial model, comparable to the factorial structure of the original English scale (affective symptoms, rumination, behavioral symptoms, anxiety about personal impact). Weak to moderate associations were found with negative emotional reactions towards the climate crisis and with general depression, anxiety, and stress.

Discussion

Our results support the original four-factorial model of the scale and indicate that the German HEAS is a reliable and valid scale to assess eco-anxiety in German speaking populations.

Measuring negative emotional responses to climate change among young people in survey research: A systematic review

BACKGROUND

Climate change is a threat to the mental and emotional wellbeing of all humans, but young people are particularly vulnerable. Emerging evidence has found that young people's awareness of climate change and the danger it poses to the planet can lead to negative emotions. To increase our understanding about this, survey instruments are needed that measure the negative emotions young people experience about climate change.

RESEARCH QUESTIONS

(1) What survey instruments are used to measure negative emotional responses to climate change in young people? (2) Do survey instruments measuring young people's negative emotional responses to climate change have evidence of reliability and validity? (3) What factors are associated with young people's negative emotional responses to climate change?

METHODS

A systematic review was conducted by searching seven academic databases on November 30, 2021, with an update on March 31, 2022. The search strategy was structured to capture three elements through various keywords and search terms: (1) negative emotions, (2) climate change, and (3) surveys.

RESULTS

A total of 43 manuscripts met the study inclusion criteria. Among the 43 manuscripts, 28% focused specifically on young people, while the other studies included young people in the sample but did not focus exclusively on this population. The number of studies using surveys to examine negative emotional responses to climate change among young people has increased substantially since 2020. Survey instruments that examined worry or concern about climate change were the most common.

CONCLUSION

Despite growing interest in climate change emotions among young people, there is a lack of research on the validity of measures of such emotions. Further efforts to develop survey instruments geared to operationalize the emotions that young people are experiencing in relation to climate change are needed.

Climate-friendly food-choice intentions among emerging adults: extending the theory of planned behavior with objective ambivalence, climate-change worry and optimism

Climate-friendly food choices are still relatively rarely addressed in studies investigating climate engagement, particularly among young people. To address this research gap, we conducted a questionnaire study with senior high school students (N = 474). Our overarching theoretical framework is the Theory of Planned Behavior (TPB), which we extended with emotional factors (climate-change worry and optimism) and attitudinal ambivalence. We found that all factors included, except for optimism, correlated with the food-choice intentions. In multiple regression analyses, worry was the second strongest predictor, after attitudes. Moreover, a measure of objective ambivalence moderated the correlation between attitudes and intentions by weakening it. The results support the validity of using the TPB model when explaining intentions to make climate-friendly food choices among emerging adults. However, our results suggest that it is also important to consider emotions-in this case climate-change worry-and the existence of conflicting evaluations about choosing climate-friendly food.

Empirical evidence for climate concerns, negative emotions and climate-related mental ill-health in young people: A scoping review

BACKGROUND

Climate change represents a serious threat to human health, including mental health, due to both the traumatizing effects of extreme climate events and the psychological effect of worry about climate change.

OBJECTIVES

This scoping review aims to search the literature for original research investigating mental health and climate-related negative emotions in young people. Findings will help to understand the current landscape, gaps in the literature, and provide recommendations for future youth mental health research and practice.

METHODS

A scoping review of the literature examining negative emotions associated with climate change in young people was undertaken. Studies published prior to March 2022 were included if they examined mental ill-health (e.g., symptoms of depression or anxiety) or negative emotions (e.g., distress, worry, concern) associated with the threat of climate change.

RESULTS

Of 3939 articles screened, 26 met the inclusion criteria. Together, studies show that young people are worried about climate change. Negative emotions about climate change were correlated with symptoms of mental ill-health. Studies also explored coping strategies young people use to manage their distress caused by climate change.

DISCUSSION

The limited literature in this area indicates a key gap in youth mental health research. While available evidence suggests that young people are concerned about climate change, more research is needed on the relationship between climate-related negative emotions and mental ill-health. Clinicians should assess for and address climate-related negative emotions in young people. Mental health leaders are urged to advocate for actions to mitigate the mental health impact of climate change.

Climate Change Anxiety Assessment: The Psychometric Properties of the Polish Version of the Climate Anxiety Scale

The Climate Anxiety Scale (CAS) is a 13-item questionnaire for assessing climate anxiety (CA) as a psychological response to climate change. The CAS consists of two subscales, namely, cognitive impairment and functional impairment. This study aimed to validate the Polish version of the CAS. The sample included 603 respondents (344 females, 247 males, and 12 non-binary), aged 18–70 years (M = 25.32, SD = 9.59). Based on the exploratory factor analysis results, we proposed a 3-factor solution (i.e., intrusive symptoms, reflections on CA, and functional impairment), which seems to be theoretically more consistent with the content of the CAS statements. The confirmatory factor analysis showed that the original 2-factor solution and the 3-factor one had a satisfactory and a good fit to the data, respectively, as well as both were invariant across different gender, age, and educational level categories. Despite the fact that the 3-factor solution had the best-fit indices, we recommended to examine the CAS structure in different samples and use the overall CAS score in cross-cultural research. Cognitive and functional impairment subscales were positively correlated with personal experience of climate change, behavioral engagement, environmental identity, and environmental motives, but they were negatively correlated with climate change denial and sense of safety. The CAS subscales were correlated with depressive symptoms, but contrary to expectations, they were not associated with anxiety symptoms and any cognitive coping strategies. The Polish version of the CAS has satisfactory psychometric properties. Overall, we reported low CA levels in the Polish sample. Women and younger people experienced higher CA.
