The present research aimed to develop the Gender Ideology Belief Scale (GIBS), a new measure designed to assess negative attitudes toward gender ideology as a coherent ideological construct.</p>Methods<p>Across two studies involving Italian participants (total N = 595), the GIBS was developed through a multi-phase process including literature review, analysis of public anti-gender discourse, item generation, expert evaluation, and psychometric testing. In Study 1 (N = 332), exploratory factor analysis was used to identify the most suitable items and examine the latent structure of the scale, whereas in Study 2 (N = 263), confirmatory factor analysis was conducted to test the factorial structure and assess reliability, construct validity, and criterion validity.</p>Results<p>The exploratory factor analysis supported a three-factor solution reflecting conspiratorial beliefs, resistance to gender-inclusive education, and adherence to traditional family values. Confirmatory factor analysis supported a second-order structure in which these three dimensions loaded onto a broader gender ideology factor, and the final 14-item version of the scale demonstrated acceptable reliability and associations with right-wing authoritarianism, sexual prejudice, and conspiracist beliefs.</p>Discussion<p>The GIBS provides researchers with a new instrument for examining opposition to gender ideology as an organized belief system rather than as an isolated attitude. By offering a multidimensional measure of anti-gender beliefs, this scale may support future research on cultural backlash, ideological resistance to social change, and the psychological dynamics underlying contemporary conflicts over gender and diversity.</p> 2026-09-16T05:37:20Z Dataset Dataset 10.3389/fpsyg.2026.1931745.s001 https://figshare.com/articles/dataset/Supplementary_file_1_Unmasking_the_anti-gender_mindset_development_and_validation_of_the_Gender_Ideology_Belief_Scale_docx/33829066 CC BY 4.0
