Résumé
Objectifs Des données révèlent que les personnes croyant à l’existence d’un lien entre les changements climatiques et la pandémie de COVID-19 sont plus susceptibles d’avoir des préoccupations pour l’environnement et d’adopter des comportements proenvironnementaux. L’objectif de l’étude est d’évaluer la structure factorielle et les propriétés psychométriques d’une courte échelle à 5 énoncés évaluant la croyance de liens entre les changements climatiques et la COVID-19 chez les adultes québécois.
Méthode Deux enquêtes en ligne ont été réalisées en mai-juin et en octobre 2021 auprès de respectivement 11 321 et 10 368 résidents adultes du Québec. Des analyses factorielles exploratoires et confirmatoires ont été utilisées afin de vérifier si les données collectées correspondent à une structure unidimensionnelle. Les validités convergente et divergente ont aussi été évaluées. La fidélité des scores de l’échelle a été estimée à partir des coefficients lambda 2 et oméga total.
Résultats Les résultats soutiennent la présence d’une structure unidimensionnelle. Plus spécifiquement, l’analyse factorielle confirmatoire consolide cette position, mais en considérant 2 covariances d’erreur dans le modèle. De plus, l’invariance de la mesure est établie pour le genre et la présence ou non d’un trouble dépressif. Les résultats des validités convergente et divergente appuient également la pertinence de l’utilisation de cette nouvelle échelle. Les valeurs des coefficients de fidélité sont excellentes et suggèrent que le degré de précision de la mesure est élevé.
Conclusion Les résultats confirment l’existence d’une structure unidimensionnelle pour l’échelle de croyance quant aux liens entre les changements climatiques et la pandémie de COVID-19. L’unidimensionnalité de l’échelle, les autres propriétés psychométriques évaluées, ainsi que l’invariance soutiennent son utilisation chez les adultes québécois. Dans un contexte où les changements climatiques s’accélèrent et que la possibilité que d’autres pandémies surviennent, cette échelle représente un outil de mesure précieux pour évaluer la croyance en la présence de liens entre les 2 phénomènes.

Abstract
Objectives Data reveal that people who believe in the existence of a link between climate change and the COVID-19 pandemic are more likely to be concerned about the environment and to take pro-environmental actions. The objective of the study is to evaluate the factorial structure and psychometric properties of a short five-item scale assessing the belief in the links between climate change and COVID-19 among Quebec adults.
Methods Two online surveys were conducted in May-June and October 2021 with 11,321 and 10,368 adult residents of Quebec, respectively. Exploratory and confirmatory factor analyses were conducted to assess whether the collected data conformed to a unidimensional structure. Convergent and divergent validity were also assessed. The reliability of the scale scores was estimated from the lambda 2 and total omega coefficients.
Result The results support the presence of a unidimensional structure. More specifically, confirmatory factor analysis consolidates this position, but by considering 2 error covariances in the model. Furthermore, measurement invariance was established both across gender and based on the presence or absence of depressive disorder, supporting the generalizability of the scale across these subgroups. The results of convergent and divergent validity also support the relevance of using this new scale. The reliability coefficient values of the scale scores are excellent.
Conclusion The results confirm the existence of a unidimensional structure for the climate change and COVID-19 belief scale. The unidimensionality of the scale, the other psychometric properties evaluated, as well as the invariance support its use among Quebec adults. The use of the total score of the 5 questions is therefore appropriate. In a context where climate change is accelerating and the possibility of other pandemics arises, this scale represents a valuable measurement tool for assessing the belief in links between the 2 phenomena.
