Alternative forms of living had their origin in the 1968-movement, which opposed directly the family. Meanwhile, this critical impulse has born many divergent forms of alternative living. Some of them have a family-analogue character together with a critical intention towards families. Thus, they are called here "Anti-Family-Families". They meet difficulties which can neither be understood by clinical theory of neurosis nor by a theory of family dynamics alone; a reconsideration of cultural and societal change must be included. This influence of change on therapeutic process is an unanswered challenge for the family therapist, who meets the influence of alternatively changed family life even in the treatment of "normal" families.
