Intervening in Family Systems with Observer Messages*

This article presents an approach to family therapy in which a group of observers becomes part of a therapeutic team by introducing strategic messages into the sessions. The observers, who operate from behind a two-way mirror, are thus able to effect change in both the family system and the therapeutic system consisting of family and therapist. Messages are described in terms of five components: function, target, timing, content, and delivery. Some guidelines for effective team functioning are given and three examples illustrate the approach. Finally, implications for training are discussed.
