Measurement invariance of the Belief in a Zero‐Sum Game scale across 36 countries.

In this paper, we examined the psychometric properties of cross‐cultural validation and replicability (i.e. measurement invariance) of the Belief in a Zero‐Sum Game (BZSG) scale, measuring antagonistic belief about interpersonal relations over scarce resources. The factorial structure of the BZSG scale was investigated in student samples from 36 countries (N = 9907), using separate confirmatory factor analyses (CFAs) for each country. The cross‐cultural validation of the scale was based on multigroup confirmatory factor analyses (MGCFA). The results confirmed that the scale had a one‐factor structure in all countries, in which configural and metric invariance between countries was confirmed. As a zero‐sum belief about social relations perceived as antagonistic, BZSG is an important factor related to, for example, social and international relations, attitudes toward immigrants, or well‐being. The paper proposes different uses of the BZSG scale for cross‐cultural studies in different fields of psychology: social, political, or economic. [ABSTRACT FROM AUTHOR]
