Resumen
Frugality is an important psychological trait that is currently of interest as a research construct in a range of fields, from consumer behavior to financial literacy and financial well-being. Increasingly, the concept of frugality is also being linked to environmental responsibility and behavior, as the core of frugality is the reduction or minimization of resources used and consumed, an emphasis on the long-term use of purchased products, and an overall conservation of resources. For many years, researchers have used the Frugality Scale (FS), the specific research tool introduced to measure frugality in a standardized and valid way. The aim of the study was to examine the psychometric properties of FS translated into the Czech language, to evaluate the uni-dimensionality of the construct, and to analyze associations with relevant variables documenting respondents? attitudes and behavior. For this purpose, the research based on face-to-face interviews among respondents representing the 15?74 years old population of Czechia was conducted. The obtained results showed that the previously developed FS achieved very good results in the Czech environment, where the obtained scores supported the hypothesized uni-dimensional structure of the scale. The CFA results show that the tested model fits well with empirical data. Convergent and construct validity is also shown to be high. Therefore, the Czech version of the Frugality Scale can be considered a reliable and valid instrument that is recommended for further use. By utilizing the FS, researchers and practitioners gain access to a robust tool for quantifying frugality and comprehending its pertinent aspects across diverse contexts.
