Using wife battering as a representative presenting problem, this paper presents an interactional, systematic framework of the therapist's management of clients who are involved in life-threatening situations, e.g., cases including suicidal threats, drug abuse, alcoholism, or child or spouse abuse. Several linear-causal theories of addressing wife-battering are discussed in detail including the victim-agressor model and the cybernetic or negative feedback/homeostatic model. Common shortcomings of each theory as models for treatment are identified. A systems approach to intervention and treatment is proposed and illustrated with a detailed discussion of how the interactional systems model might work in treatment with an abused wife. This systems approach to treatment for abuse is illustrated in a case example providing initial client presentation of problems and the intervention strategies used. Implications for a wider application of this systems model of intervention are discussed. (PAS)
