The principles and process of a model of clinical supervision for psyc
hotherapy are presented and described through two cases. The model dra
ws heavily from Bowen's family systems theory and Peplau's theory of i
nterpersonal relations. The relationships in the client-family, client
-therapist, and therapist-supervisor systems mirror each other, and ch
anges in self-definition, and in the management of anxiety of persons
in one system catalyzes changes in parallel systems. Two cases illustr
ate the model. In the first case, anxiety needed to be raised to level
s optimal for learning. In the second case, no learning occurred until
levels of anxiety were reduced.
