[Possible interferences in planned and unplanned transitions between single and family therapy].

Especially therapists trained for diagnostic and therapeutic work with individuals who are working in an area where they are compelled to include the patient's relatives into the therapy must be careful of the consequences resulting from a possible blending in with systemic epistomology. With the example of a diagnostic interview it is demonstrated where these various parameters differ and what they have in common and where their specific influence upon the therapeutic effect lies. This is considered a necessity with regard to avoiding adverse interferences.
