In classical compulsion, there is an underlying conflict: frowned-upon impulses—whether sexual, rivalrous, or self-assertive—clash with a conscience that is experienced as alien and directed against one’s own self. Reaction formation and affect isolation— Transformation into its opposite; separation of thought and feeling – as well as denial keep this conflict unconscious. These are defense mechanisms.
The situation is different in cases of severe structural disorders. Here, the ritual provides stability and protects against a sense of inner disintegration. Interpretations that focus on conflict can then have a destabilizing effect. What is needed are supportive interventions that strengthen structure.
This distinction determines the course of treatment, and it also determines the prognosis: The first form can be treated much more successfully using psychodynamic methods than the second.
