Abstract

Background and aim
Climate Change (CC) is a worldwide concern with important consequences for Public Health. A more sustainable and responsible way of living is necessary in order to reduce CC consequences, and adequation to this is directly related to risk perception and knowledge about the phenomenon. The aim of this study was to validate a questionnaire to measure the knowledge of Italians on CC and its consequences.


Material and methods
The questionnaire was administered online to high school students, their parents and teachers that were participating to a meeting at Sapienza University. The questionnaire contained a sociodemographic section and 19 questions on causes and consequences of CC and ways to fight it. The statistical analysis was performed with Statistical Package for Social Sciences (SPSS) version 25.


Results
Sixty-four individuals answered the online questionnaire. The analysis of internal consistency was performed by 12 dichotomous variables that measured the knowledge level on CC. The analysis showed a standardized Cronbach’s alpha equal to 0.39, corresponding to a low reliability. When females were excluded, the alpha value rose to 0.497, and ascended to the reliable value of 0.639 when refining the selection of the included questions.


Conclusion
The Cronbach’s alpha value found showed a low reliability but achieves acceptable levels when considering only males and excluding some of the initial questions. Future studies should be performed in order to highlight the reliability of this tool to assess the knowledge about CC among the population
