Hypothesizing--circularity--neutrality: three guidelines for the conductor of the session

This paper presents the results of our research focused on individuating and elaborating principles and methods that we have found highly productive in interviewing the family.

Our purpose is to aid the therapist in stimulating the family to produce meaningful information, which is indispensable to the therapist in making a therapeutic choice.
