These unusual persons have been given a variety of names: schizoids, schizoid psychopaths, and the condition called schizoidia or schizophrenia-spectrum illness (Kahn, 1923; Planansky, 1966). With recent developments in family and adoptive studies of schizophrenia which have indicated a genetic factor playing a causative role, the schizoid state has assumed more importance, especially in estimating the type of inheritance (Heston, 1970). Furthermore, the schizoid state is of considerable interest from a clinical standpoint since it may represent a \u2018forme fruste\u2019 of schizophrenia, and as such a study of schizoids from the point of view of the factors which may have prevented a full-blown schizophrenic process would be of great interest.<\/jats:p>","DOI":"10.1192\/bjp.122.6.679","type":"journal-article","created":{"date-parts":[[2008,8,12]],"date-time":"2008-08-12T22:35:43Z","timestamp":1218580543000},"page":"679-685","source":"Crossref","is-referenced-by-count":13,"title":["Toward a Definition of the Schizoid State: Evidence from Studies of Twins and Their Families"],"prefix":"10.1192","volume":"122","author":[{"given":"Remi J.","family":"Cadoret","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"170","published-online":{"date-parts":[[2018,1,29]]},"reference":[{"key":"S0007125000057007_ref22","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1971.01750110034006"},{"key":"S0007125000057007_ref21","volume-title":"Clinical Genetics in Psychiatry","author":"Mitsuda","year":"1967"},{"key":"S0007125000057007_ref2","first-page":"1","article-title":"\u2018The family in the pathogenesis of schizophrenic and neurotic disorders.\u2019","volume":"42","author":"Alanen","year":"1966","journal-title":"Acta Psychiatrica Scandinavica"},{"key":"S0007125000057007_ref4","unstructured":"Essen-M\u00f6ller E.
