The project included 177 participants; specifically, the sample comprised 39 homosexual, 15 bisexual and 31 heterosexual women, and 56 homosexual, 5 bisexual and 31 heterosexual men. Results.

There were no significant differences in the perception of maternal attitudes between homosexual and heterosexual men. The study showed significant differences in the perception of paternal attitudes in terms of the Inconsequential Attitude Scale between homosexual and bisexual women (p=0.023) and between heterosexual and bisexual women (p=0.035).
