Measurement of attitudes toward lesbians and gay men in students of health sciences from northeast mexico

The aims of this paper were to describe the distribution of the Attitudes Toward Lesbians and Gay men scale (ATLG; Herek, 1984), estimate the percentages of rejection, and provide evidence regarding its concurrent validity. An incidental sample of 452 undergraduate students of health sciences was collected. The distribution of ATLG total score fitted to a normal distribution. The percentage of rejection was 18% (including 3% extreme rejection). The correlation between the ATLG total score and a homophobia scale was positive and with a large effect size. Male participants showed higher scores of open rejection toward gay men than female participants. The means of ATLG total score were higher in heterosexuals than non-heterosexuals, and in persons not having homosexual friends or relatives than in persons who did have, and in students who had started their couple sexual life than in those who had not. Hence, validity evidences were found. It is recommended the use of ATLG scale in Mexico.
