Non-heterosexuality is actually computed out-of several variables that asked about the fresh strength of being attracted to folks of an equivalent together with opposite sex (anchored that have “no way” – code 0, and “surely yes” – code 100; we designed to prohibit people victims who respond which have “0” on both balances but zero such as subject participated in the latest study). Non-heterosexuality is addressed as the a digital variable which have step 1 equal to becoming sexually interested in people of the same sex for the same or higher power rather than people of the opposite sex.
From inside the heterosexuals, i assessed what amount of sexual lovers of common sex due to the fact number of sexual partners of your opposite sex inside the past 12 months (nine kinds: “0” – password 1, “1” – code 2, “2” – password 3, “3” – code cuatro, “4” – password 5, “5–6” – code six, “7–9” – code 7, “10–19” – code 8, “20 or higher” – code nine).
