Contributions for modeling the psychotherapeutic process of change.

This essay is a contribution to the discussions on the modeling of the psychotherapeutic process of change. Three aspects are highlighted: an evaluation of the emergence and transformation of novelty in the narratives of the clients; the inclusion of the psychotherapist as a dialogical partner that constructs with the client her new narratives; and a tentative analysis of the meaning-making of this construction along the successive moments of the dialogical exchanges between the client and the psychotherapist. It is finally pointed out some gains in modeling the client-psychotherapist dialogical process of (ex)changes.
