Personality variations in healthy relatives of schizophrenics.
A familial relationship between schizophrenia and schizotypal personality disorder is widely acknowledged; the familial relationship between schizophrenia and the broad continuum of schizoid personality variation is less clear. In a comprehensive family study healthy relatives of schizophrenics were compared by self rated personality features with relatives of unipolar depressed patients and with relatives of controls. The dimension of schizoidia was not able to distinguish the groups of relatives. However, relatives of schizophrenics (in particular male relatives) scored higher on 'normalized' personality dimensions such as 'rigidity' and 'neuroticism'. Healthy relatives of probands with unipolar depression revealed a similar deviant pattern.
