Family therapy is a particularly useful mode of treatment when family dynamics and functioning are problematic. In family therapy the focus is the family unit itself. The family therapist works from an understanding that all parts of the family are interrelated and that change in one area affects the overall functioning of the whole. Oftentimes, when family members are having difficulty, there are patterns of interaction that have become destructive to the well being of the family. In working with the family, it enables the therapist to address the problems of family members by directly intervening in the context in which the difficulties occur what reinforces them. Interventions focus on addressing and modifying the obstacles which exist in the family system, helping family members communicate with one another in a productive way, and in helping them to working together toward more effective problem resolution.
