An exploratory study of a new psychological instrument for evaluating sustainability: The Sustainable Development Goals Psychological Inventory

The psychometric properties of the Sustainable Development Goals Psychological Inventory (SDGPI) are verified, by employing quantitative and qualitative approaches, in order to obtain a thorough comprehension of the self-perceptions of the sustainable development goals by the Italian participants in this research. The reliability, dimensionality, and aspects of concurrent validity were tested for the SDGPI. Three unidimensional factors (interest, motivation, and self-efficacy) were shown to be prevalent using exploratory factor analysis. Furthermore, the SDGPI showed adequate concurrent validity and internal consistency in the present study. To broaden the quantitative findings, responses to open-ended questions were analyzed. The results suggest perspectives for future exploration and actions regarding the psychology of sustainable development and sustainability.
