This research was aimed at the analysis of treatment-programs offered by 13 wards of a hospital for mental health care and the characteristics of the 264 chronically mentally ill, receiving these treatments. Treatment-programs were found to be rather homogeneous where as patient characteristics showed considerable heterogeneity in both psychopathology and social functioning.

Among the results it was found that the treatment-programs in general, were not grafted upon the requirements of individual patients. As suggested in former reports a `homogeneity approach', which usually characterizes the policy of hospital care for the chronic mentally ill, may be held responsible for the less then optimal professional care.
