[Which factors modify drug-compliance?].

Since the extent of medication noncompliance in schizophrenic patients ranges between 50 and 60%, evaluation of factors that are associated with noncompliance has become an important issue. 197 schizophrenic patients have been interviewed with regard to numerous issues: Form and type of medication; information about side effects; attitude of patients towards illness and medication. Our data suggest that information about benefits and side effects, as well as the attitude of patients towards illness and medication play an important role in the adherence to the treatment regimen.
