As a Narrative therapist, I am intrigued by the concept of "rescuing the said from the saying of it" (David Newman, 2008). This means making an effort to capture, through written documents, any significant ideas, thoughts, questions or stories we discussed. I then send this document to clients following our sessions. (Please note that time constraints can at times affect the frequency and length of these documents.)
People have indicated that this practice allows them to know they have been heard (or gives them the chance to correct my understanding if they have not!), and is helpful in teasing out problems so that they can be dealt with in greater clarity.
