Here are two sample quizzes created by Gottman that help couples to assess where they are in their relationship, and if it may be in trouble. The first quiz, How Well Do You Know Your Partner?, the level of friendship in a marriage is evaluated. According to Gottman, friendship is one of the most important elements in a successful relationship.
The Bids for Connection quiz examines how often bids, or the fundemantal elements of emotional connection, are shared between a couple. Examples of bids for connection may include eye contact, a touch on the arm, or a simple smile.

Your score for questions 1-3:
Scores below 8 mean that you are direct in your relationship. This is great news for your relationship, because you have the ability to state clearly what you need from this person. If your score is 8 or higher, you may be too reticent in bidding. The other person in your relationship may feel as if they have to be a mind reader to understand what you need.

Your score for questions 4-6:
Scores below 8 mean that you are not overly forceful in expressing what you need from this person. Your relationship benefits from this quality of yours because it's easier for the other person to hear and understand what you need. If your score is 8 or higher, you may be expressing so much anger in your bidding that you are turning this person away. Maybe this is because of past frustrations, or maybe it is the way your personality is.

Your score for questions 7-9:
If your score is below 8, this means you have a high level of trust in your relationship. If your score is 8 or higher, this reflects a problem with the level of trust in your relationship. You may need to do more to win this person's trust. Some people accomplish this by concentrating more on responding to the other person's bids, rather than trying to get the other person to respond to you.
