Resum
The empirical study of negative attitudes toward gay and lesbian
people (homonegativity) is a way to understand the reason for its
prevalence. The aim of this study was to examine the psychometric
properties of a Spanish version of the Attitudes Toward Lesbians
and Gay Men Scale (ATLG). A total of 359 undergraduate students
were recruited from two different cities in Colombia, South
America. Participants’ attitudes toward gays and lesbian people
were assessed using the ATLG Scale and the Homophobia Scale;
anxiety was measured using a short version of the Zung Self-Rating
Anxiety Scale. Internal consistency analyses have shown that the
ATLG Scale is a reliable measure of homonegativity in a Colombian
sample. In addition, principal components analyses, as well as convergent
and divergent validity analyses have confirmed that the
ATLG Scale is a valid and reliable measure of homonegativity in the
Colombian context and support its use as a research instrument.
