RT Journal Article SR Electronic A1 Lenghart, Daniel A1 Čerešník, Michal T1 Psychometric properties of the Discriminatory tendency towards sexual and gender minorities scale (DT-SGM-18) in online sample of slovak adults JF Diskuze v psychologii YR 2025 VO 5 IS 2 SP 1 OP 9 DO 10.5507/dvp.2024.002 UL https://diskuzevpsychologii.upol.cz/en/artkey/dps-202302-0001.php AB The aim of study was to validate the psychometric properties of the newly constructed Discriminatory Tendencies toward Sexual and Gender Minorities Scale (DT-LGBT-18). The research was conducted through a quantitative methodology that consisted of two questionnaire methods. The first method was the Discriminatory Tendencies Towards Sexual and Gender Minorities Scale (Lenghart & Cherry, 2022a), which is a compilation of items from foreign methods (Hill & Willoughby, 2005; Hoffarth et al., 2016; Morrison & Morrison, 2002). The Prosocial Tendencies toward the LGBTQIA+ Community (Lenghart & Cheresnik, 2022b) method was used in the context of validation. The research population consisted of 2019 adult Slovaks whose mean age was 27,33 (SD = 8,07). The results of the study show that the author's instrument is suitable for use in measuring dsicrimination tendencies towards selected sexual and gender minorities in the territory of the Slovak Republic.
