Multidimensional Scale of Sexuality (Berkey MSS)
45 items — 9 sexual orientation categories, True/False
Are traditional labels too limiting? The Berkey MSS (1990) maps your sexual orientation across 9 categories × 5 content types (Sexual Attraction, Erotic Fantasy, Sexual Behavior, Arousal to Erotica, Emotional Factors) — giving you a richer picture than a single label. 45 True/False items, about 10 minutes.
How do you understand your sexuality?
The Multidimensional Scale of Sexuality (Berkey MSS) measures sexual orientation across multiple dimensions: attraction, behavior, identity, and fantasy. It recognizes that sexuality is complex and can't be captured by a single label.
The dimensions of sexuality
- Sexual attraction — who you're drawn to
- Sexual behavior — who you've been with
- Sexual identity — how you label yourself
- Sexual fantasy — who you think about
About this scale
The Berkey MSS was developed to capture the complexity of sexual orientation. Research shows that these dimensions don't always align — someone might be attracted to one gender, have sex with another, and identify differently.
This assessment helps you understand your sexuality across multiple dimensions. Use it to think through how you experience your sexuality.
Sexual orientation exists on a spectrum and can be fluid over time. There are no right or wrong answers — only what's true for you.
