Validación de la prueba de homonegatividad internalizada en el departamento de Nariño (Colombia).

This study focuses on analyzing the psychometric properties of the Internalized Homonegativity Test among homosexual individuals in the department of Nariño (Colombia), aiming to develop a relevant and adapted instrument for gender and sexual orientation studies in the region. It employs a quantitative instrumental cross-sectional design with a sample of 161 participants, including both gay and lesbian individuals from 25 municipalities in Nariño. Participants' ages ranged from 15 to 87 years, selected through convenience sampling using the Snowball method. The Internalized Homonegativity Test, the Homosexual Sexual Orientation Recognition Scale, and a SociodemographicGenerational Questionnaire were administered. Exploratory and confirmatory factor analyses, correlation and hypothesis testing, and calculations of Cronbach's Alpha and McDonald's Omega were conducted using JASP V 0.17.1 software. The results indicate that the instrument exhibits a unifactorial structure explaining 56.4 % of the common variance in the data and adequate internal consistency, with reliability values ranging from 0.828 to 0.894. These findings support the scale's reliability for measuring internalized homonegativity in the studied context. [ABSTRACT FROM AUTHOR]
