Four single-item scales measure physical and emotional attraction to the same and opposite sex independently — no composite score, just four separate profiles.

Is sexual orientation just "same" vs "opposite"?

The Shively SSO doesn't think so. It breaks orientation into four independent threads: physical attraction and emotional connection, each rated for same-sex and opposite-sex separately.

Shively & DeCecco (1977) published this model decades before "romantic orientation" became a common term. The core idea: who you're physically attracted to and who you form emotional bonds with aren't necessarily the same thing.
