Creating a 'social zeitgeber' to synchronize family emotional rhythms: A new therapeutic approach in child and adolescent psychiatry.

A family can be viewed as a system respecting the principle of homeostasis and therefore considered as a system in equilibrium or out of equilibrium, or even both simultaneously or consecutively. Within a family system, there are oscillatory phenomena and synchronization of the emotional, behavioral and relational rhythms of each member of the family system as well as synchronization of this system with others. A disruption of family synchronies, consisting of successive desynchronizations and resynchronizations, can take place in order for a change to occur. We created a mobile team for preadolescents and adolescents with psychological difficulties and their families; this mobile team enables to trigger a change by acting on the family synchronies like a 'social zeitgeber', i.e. an external factor synchronizing social and biological rhythms. The mobile team acts by disrupting the synchronies of the family system and this disruption is facilitated by a state of crisis experienced by the family. More specifically, the mobile team intervention provokes changes in the family representations associated with changes in the family emotional climate, measured by expressed emotion, due to disruptions in the synchronization of certain rhythms (desynchronization and then resynchronization of these rhythms), and could therefore be considered as a 'social zeitgeber'. It creates an experience that becomes part of the individual's and family's history and could be reactivated in the future if necessary. Finally, it allows the family and the adolescent with difficulties to reach new perspectives and representations which participates to the process of change, but also to benefit at the same time from a secure basis and frame created by the (re)synchronization of family emotions through the intervention of the mobile team following a ritualized procedure.
