Objectives. This study aims to evaluate the psychometric properties of the Slovak version of the SciPop scale, designed to measure science-related populist attitudes. It seeks to explore its factor structure and investigate its relationships with external variables such as political populist attitudes, trust in science, distrust of experts and perception of science. Sample and settings. Data collection was conducted in August 2023 through an online panel of a local research agency. Ethical approval was obtained, and informed consent was secured from 643 Slovak participants. Quota sampling ensured demographic representation based on gender, age, education, and regional affiliation. Statistical analyses. Factor structure was examined using MIMIC model with ML estimator in the R software. Measurement invariance across gender, age and education groups was assessed. Correlations with selected constructs were examined. Results. The findings indicate that the Slovak version of the SciPop scale exhibits robust psychometric properties, including a four-dimensional factor structure and measurement invariance across gender, age, and education. Significant associations of science-related populism with political populist attitudes, trust in science, distrust of experts, and perceptions of science were confirmed. Limitations. Limitations include the use of an online sample, which may not fully represent certain population groups, and reliance on self-report measures. To ensure the scale’s stability and generalizability, further validation on diverse datasets and test-retest reliability assessments are recommended.

Ciele. Výskum populizmu posledné desaťročie napreduje, čoho znakom je navrhnutie niekoľkých škál na meranie populistických postojov. Žiadna z nich nebola overená v podmienkach Slovenska, kde sú populisti dlhodobo súčasťou koalície aj opozície. Cieľom tejto štúdie bolo overiť psychometrické vlastnosti štyroch škál populistických postojov, ktoré sa často používajú a overujú v medzinárodných výskumoch, na slovenskej vzorke. Participanti a postup výskumu. Dáta 832 resondentov, získané pomocou online panelu v novembri 2021, boli analyzované pomocou softvéru R. Výskumná vzorka bola reprezentatívna z hľadiska distribúcie pohlavia, veku, úrovne vzdelania a príslušnosti k regiónom Slovenska. Štatistická analýza. Pôvodné škály boli testované pomocou exploračného súboru dát (N = 416). Modifikované škály boli overené pomocou konfirmačného súboru dát (N = 416). Výsledky. Výsledky ukázali, že pôvodné škály nezodpovedajú dátam. Po niekoľkých úpravách však boli dve škály validované na slovenskej vzorke. Škály boli invariantné pre pohlavie, vek a dosiahnuté vzdelanie. Limity. Možným nedostatkom validovaných škál populistických postojov je nestabilita pri predikcii volebného správania, ktorá je diskutovaná v kontexte výsledkov iných štúdií a tiež v politickom a kultúrnom kontexte Slovenska.

Objectives. Research on populism has progressed over the last decade and several scales have been proposed to measure populist attitudes. None of these has been validated in the context of Slovakia, where populists are a long-term part of both coalition and opposition. This study aimed to verify the psychometric properties of four populist attitudes scales that are frequently used and verified in international research, on a Slovak sample. Participants and setting. Data of 832 respondents collected using an online panel in November 2021 were analyzed using the R software. The research sample was representative according to the distribution of gender, age, education, and regions in Slovakia. Statistical analysis. The original scales were tested using an exploratory dataset (N = 416). The modified scales were verified using a confirmatory dataset (N = 416). Results. The results showed that the original scales did not fit the data. However, after several modifications, the two scales were validated on the Slovak sample. The scales were invariant across the gender, age, and educational groups. Limits. A possible shortcoming of the validated populist attitudes scales is the instability in predicting electoral behavior, which is discussed in connection with the results of other studies, and the Slovak political and cultural context.
