40 acute schizophrenic in-patients were examined using a rating scale (AMP-system) and a self-report questionnaire (APZ) immediately after their admission and on average 7 weeks later. The aim of the study was to clarify the usefulness of self-report questionnaires in schizophrenic patients. There were four groups of subjects: 1. Patients, who filled in the questionnaire immediately after admission, 2. patients, who did not at this phase of their illness, 3. patients, who filled in the form 7 weeks later during remission and 4. patients, who did not. The main questions were: --Are their any differences in the psychopathology between testable and untestable patients immediately after admission resp. during remission 7 weeks later? --How do the psychiatrist's ratings and the self-ratings correlate in different phases of the illness? If was found that the degree of psychopathology correlated negatively in the acute state with the capacity to perform a self-rating. Seven weeks later during remission this correlation could not be found anymore. Motivational variables of staff and patients in influencing the testability are mentioned. It is also shown that there are selfreports and rating-scales. The correlations are different during the two phases of the illness.
