Variables related to sexual prejudice among Mexican health science students

AbstractBackgroundThe stigmatization and discrimination of non-heterosexual persons is a reality in some institutions of the Health Services, and among health sciences students.ObjectivesTo describe and predict the level of sexual prejudice in health sciences students, taking into account a set of qualitative and numerical variables on socio-demographic data, sexual life, social life, university (private or public) the student's major (medicine or psychology), and clinical aspects.MethodologyA socio-demographic and life-history data questionnaire, an 8-item homophobia scale and a 16-item internalized homonegativity scale were applied to a non-probabilistic sample composed of 231 health sciences students. The predictive models were estimated by analyses of multinomial and ordinal regression.ResultsTwelve percent of participants exhibited an attitude of open rejection towards non-heterosexual persons (including 0.9% who exhibited extreme rejection). Non-heterosexual orientation, having non-heterosexual friends and acceptance of one's own homosexual desires were variables associated with lower levels of open rejection towards non-heterosexual persons. Only the two latter variables were significant predictive variables; they explained 21% of the variance in the ordinal regression model and 27% in the multinomial regression model. The percentage of the correct classification of cases of acceptance was high but the percentage of the correct classification of cases of rejection was low.ConclusionThe level of open rejection towards non-heterosexual persons is low. An exclusively heterosexual identity, affirming not to share aspects of the sexual sphere and not having personal contact with the stigmatized subject are determinants of open rejection. There exist other variables that were not taken into account in this study, as is deduced by the high percentage of unexplained variance
