Abstract: | This typology of families is composed of five family systems named “Two Against the World”, “Children Come First”, “Share and Share Alike”, “Every Man for Himself”, and “Until Death Do Us Part”. Each may occur as a pure form but mixtures are common. Variables such as purity of the system, timing of the emergence of a system and the family's flexibility in shifting from one system to another determine outcomes for sickness or health. The therapist's ability to recognise these systems gives coherence to family therapy and improves its effectiveness. |
