The research investigated (a) the connection between attitudes toward homosexuality and same-sex parenting; (b) the socio-demographic and socio-cultural variables linked to such attitudes; and (c) the knowledge behind these attitudes. The 223 participants completed a self-report questionnaire including the Attitudes Toward Lesbians and Gay Men Scale (revised version), an attitudes toward same-sex parenting scale, and a personal data form, and answered some questions about their knowledge of homosexuality. The results showed an association between attitudes toward homosexuality and attitudes toward same-sex parenting, and a connection between socio-demographic variables, knowledge about homosexuality and same-sex parenting, and positivity/negativity levels of attitudes.
