Concordancia entre dos formas de investigar la orientación sexual en adolescentes de Santa Marta, Colombia

Since sexual minorities are victims of discrimination, it is possible that teenagers do not accurately report their sexual orientation. There are differences in the frequency of non-heterosexual behavior according to the way it is investigated; however, concordance between these ways has not been explored yet. The objective was to establish the concordance between two ways of researching sexual orientation among students at Santa Marta, Colombia. In this survey, 3575 students participated, 57% were girls, with a mean age of 13.6 (SD=1.9), and mean scholarship, of 8.2 years (SD=1.6). Sexual orientation was established by means of direct and indirect questions. Cohen's kappa showed concordance beyond chance. Observed concordance reached 76.8%, and Cohen's kappa, 0.368 (95% CI 0.337-0.399). Concordance between the two ways of asking about sexual orientation was found to be low. Investigation of sexual orientation should include research objectives and result implications as criteria.
