Relationships, according to New York psychiatrist Daniel Casriel, require communication on three levels: the emotions, touch and words or symbols. Casriel devised this test of "factors in a relationship" partly as a way of allowing people to determine how they see themselves as a couple.

Without consulting one another, partners can score each other on these factors:

* Sensuality (your pleasure in how your partner looks, feels and smells to you), 0-4.

* Sexuality (your pleasure in how your partner satisfies you sexually), 0-4.

* Intellectuality (how much you appreciate communicating ideas to each other), 0-4.

* Emotionality (how well you can share emotions), 0-4.

* Friendship/trust (on your side and there for you when you need them?), 0-4.

* What's been built together (home, family, the things that take time), 0-5.

Add the scores together, then multiply by four. Casriel's interpretation of scores: 0-25 bad, 26-50 poor, 51-70 fair, 71-85 good, 86-100 excellent.

If both people in the relationship are willing to work to improve, the score can increase by 16 to 24 points, claims Casriel, but the test will mean different things to different people. If one partner, for example, rates sexuality 0 and the other rates it 4, their sex life is probably a problem area.
