One suggestion is to divide note taking into 3 sections: speaker, content, process observations.

Be alert for expressions, body movements, interruptions, topic changes, and times that one family member disconfirms another by ignoring, changing the topic, disparaging the speaker, or bringing in a third party.

• . Who sits close to whom?
• . Who's farthest away from whom?
• . Does this proximity and distance reflect the level of verbal involvement between members or not?
• . Who talks to whom?
• . What is the emotional climate in the family, what they talk about and the way they interact during periods of calm versus periods of tension?
