Non-heterosexuality is actually computed out of several variables you to definitely inquired about the fresh new power of being interested in individuals of a comparable plus the reverse sex (anchored having “no way” – password 0, and you can “seriously yes” – code 100; i meant to exclude one victims that would behave that have “0” into each other scales however, no eg topic participated in the study).
