--- - |2+ Objectives We developed and validated the POPulist ORientation (POPOR) Scale (composed of six five‐category items), operationalizing populist orientation as a unidimensional construct composed of six facets: (1) anti‐economic, financial, and intellectual establishment attitude; (2) anti‐political establishment; (3) conception of the people as a homogeneous and virtuous entity; (4) consideration of the people as legitimated to take part directly in political decision‐making processes; (5) need for a strong leader; and (6) loss of relevance of the traditional ideologies. To prevent response bias, we gave the POPOR Scale a forced‐choice format and a balanced structure. Method We surveyed a quota sample of 1,348 Italians extracted from the general population and analyzed the structure of the scale and its convergent validity via confirmatory factor analysis. Results The POPOR Scale showed a unidimensional structure and a good convergent validity. Supplemental analyses showed its structural invariance across gender, age, education, and area of residence. - 'Social Science Quarterly, Volume 100, Issue 6, Page 2148-2167, October 2019. '
