Abstract
Author attempted of find out whether there were any characteristic findings in the sibling schizophrenics family(family in which more than two members of sibling were schizophrenia) including clinical features, interpersonal relationship and some of sociodemographyic aspects. Data for the sample were obtained 17 schizophrenics from 8 sibling schizophrenics families who were admilted to neuropsychiatric department EWHA Womens University Hospital from March 1st 1973 to February 28th 1983. Results obtained were summerized as follows; The members of sibling were larger in the schizophrenics families than that of normal and the first born childrens and last born childrens were affectes more frequently than subseguent ones. Sibling schizophrenics were tended to be heigh educates, no employed and low middle socioeconomic class. In the familial history, sibling schizophrenic's father proband had more frequently affectes than mother proband. Usually mother's characters were found to be over protective and active but father's were indifferent and passive. Their father and mother had mother dominent and hostile relationship. Interpersonal relationship between sibling schizophrenics had relative affective(41.2%) in the majority. Comparative analysis of the above finding showed no differences from the family in which only one child was afflicted schizophrenia.
