Validity and Reliability of a Tool for the Identification of Consumer Attitudes Toward the Access to Freshwater in Households in the Context of Sustainable Development

The global water situation is deteriorating not only due to the progressing climate change but also to irrational consumer behaviors, which are driven by attitudes. Given the above, it seemed essential to identify attitudes toward the issue of access to freshwater in households, considering sustainable development guidelines. The aim of this study was, therefore, to develop a research tool for the identification of respondents’ attitudes toward this problem and then to determine its validity and reliability. The object of the study was an original questionnaire serving as a research tool for identifying the specified attitudes. The data required for this study were acquired through a critical review of the literature and a questionnaire survey method. The study was conducted in one of the Polish urban agglomerations using the Paper-and-Pencil Interviewing (PAPI) technique. An in-depth analysis of the validity and reliability of the tool, carried out using a statistical procedure, confirmed it to be a viable means to identify these attitudes in Poland. Therefore, there are reasonable grounds to assume that, following the application of the procedure presented in this manuscript, the developed tool may also be used to identify the specified attitudes when implemented in a different population.
