Factors affecting the family support system of patients with schizophrenia: a survey in the remote island of Tsushima

Possible support for home-cared schizophrenic patients and their families was investigated on Tsushima, one of the many isolated islands in Japan. The psychopathologic symptoms of the patients were evaluated using the Brief Psychiatric Rating Scales (BPRS), their social adjustment using the Psychiatric Disability Assessment Schedule (DAS), mental states of the families using the General Health Questionnaire (GHQ), and the quality of life (QOL) using the Life Satisfaction Rating Scales (LSR). The family support systems for the patients were evaluated with regard to: (i) family support for the patient's daily life (FS), (ii) hardships of family life caused by living with the patient (HF), and (iii) empathic attitude of the family toward the patient (EA). Psychotic symptoms of schizophrenic patients were closely related to the mental state and QOL of their families. Family support was significantly correlated with HF and EA. Moreover, the family support system was shown to be related both to the psychotic symptoms of the patient and the mental state of the family. These results suggest that an approach to improve the family support system for the patient may exert positive effects on the patient's psychotic symptoms and his/her social adjustment. We also consider that intervention by a public organization is necessary to improve the family support system on islands.
