The aim of this study is to determine whether the frequency of using ethical codes of university students differs according to gender identity and sexual orientation variables. The sample of this descriptive study consists of 200 university students from various universities and departments. Ethical Worldview Scale developed by Walker and Jensen (2016) and adapted into Turkish by Dost Gözkân (2016) was used for data collection. The results of two-way multivariate analysis of variance denoted that subcategory points differed significantly with respect to sexual orientation, did not differ significantly with respect to gender identity and the interaction effect of gender identity and sexual orientation was not significant.
