This study aimed to compare the level of attitudes toward homosexuality among nurses in Taiwan between 2005 and 2017 and with various demographic characteristics, as well as the roles of demographic characteristics in the changing trend of attitudes toward homosexuality between 2005 and 2017. This survey study recruited nurses from three hospitals in 2005 (Survey 2005, = 1176) and 2017 (Survey 2017, = 1519). Participants' four dimensions of attitudes toward homosexuality, including condemnation, immorality, avoiding contact, and stereotypes, were assessed using the Taiwanese version of the Attitudes Toward Homosexuality Questionnaire. The results demonstrated that nurses in 2017 exhibited lower levels of avoiding contact with lesbian and gay patients and stereotypes toward homosexuality but higher levels of condemnation of gay and lesbian individuals and perceptions of gay and lesbian individuals as immoral than did nurses in 2005. Age moderated changes in some dimensions of attitudes toward homosexuality from 2005 to 2017. The need to develop training programs aimed at improving not only the quality of nursing skills but also their negative attitudes regarding homosexuality is urgent.
