In this article, a model of quality assurance for inpatient psychother
apy is discussed, which was developed in cooperation between researche
rs and clinicians. This model is based on the concept of internal qual
ity assurance with external help. The Heidelberg Model of Active Inter
nal Quality Assurance has three elements: (1.) a QA-Inventory for rout
ine monitoring; (2.) rules for evaluating the outcome of every patient
and (3.) a feedback model for communicating the results to the therap
ists (quality circles). The focus of this model is the recognition of
problematic results. It is mainly these results that will be discussed
in our quality circles, where the outcome of treatments from the pers
pective of the inventory and of the therapists are discussed. This fee
dback model and the quality circles will be explained with three examp
les of patients. The Heidelberg Model of Active Internal Quality Assur
ance will be seen as the basis of a concept of Quality Assurance, whic
h is aimed at assuring and improving the quality and rationality of th
e psychotherapeutic service.
