Non-heterosexuality are computed off a couple of parameters you to definitely asked about the new strength to be keen on folks of the same and the reverse sex (anchored having “absolutely not” – code 0, and you may “absolutely yes” – code 100; we designed to prohibit one sufferers who would work with “0” to the each other scales but zero for example subject participated in brand new study). Non-heterosexuality are addressed because a binary variable having step 1 equal to being sexually keen on people of a similar sex to your exact same or even more strength than to individuals of the exact opposite sex.

In heterosexuals, i reviewed how many sexual couples of your prominent sex while the number of sexual couples of your own contrary sex within the during the last seasons (nine kinds: “0” – password step one, “1” – code 2, “2” – password step 3, “3” – code cuatro, “4” – password 5, “5–6” – password six, “7–9” – password 7, “10–19” – code 8, “20 or higher” – password nine).
