The adolescent's experience of divorce needs to be understood within a developmental and systemic framework. Problematic or symptomatic behaviour in teenagers from separated families often reflects on the family's difficulty in managing the transition to a new and different family organisation. The type of problem or symptom presented is shaped partly by the developmental characteristics of the adolescent period, as well as being indicative of unresolved problems within the broader family system. Problem resolution can often require the involvement of both separated parents and their children in a conjoint interview, in which case a strategic family therapy approach can be particularly useful. A strategic approach offers the therapist clear guidelines regarding the focus and process of the interview, and assists the therapist to be in charge whilst remaining neutral in the sense of not allying more with one side or another. Case illustrations are included of a strategic approach with teenagers and their separated families.
