The purpose of the study was to clarify the attitude of patients with schizophrenia and paranoid psychoses towards hospital personnel and treatment procedures during the two pre-suicidal months. The study was carried out on subjects from south Finland who had committed suicide during a three-year period and had been treated under these diagnoses. The controls included suicides who had received psychiatric treatment for other reasons. A questionnaire was issued to ascertain the opinions of the doctor last in charge of the patient and other personnel. Both groups answered independently, and the opinions given were almost the same. Both groups stated that during the last pre-suicidal months the patients with schizophrenia and paranoid psychoses had shown a more negative or indifferent attitude towards personnel than the controls, and their attitude towards medication had been clearly more negative. Among them there were considerably more patients who had ceased to request support or attention. Thus these patients had developed a degree of despair which manifested itself in a negative attitude towards personnel and treatment.
